Hey there!
I've had my 1+3T for about 8 months now, and in the past two months (or so), instead of the usual 4-6 hours of SOT, I've been only getting 1.5-2 hours.
I settled with (at the time @apascual89's, now developed by @akhilnarang) ResurrectionRemix which has always worked like a charm, but it's been acting up recently. I have downloaded wakelockDetector, BBS, and looked at CPU stats from Kernel Adiutor. Phone wasn't getting any deep sleep at all, it's been constantly running. I have been dirty flashing for months at the time, so I decided to do a full clean flash (I was encrypted at the time, so I even formatted userdata), hoping it would do something, but it didn't.. really?
After setting everything up, and waiting a few charge cycles, it went back to crap again. ~2 hours of SOT, with twice as much "awake with screen off" as screen on time. Battery was draining 2-3% per hour with no use whatsoever. See the following pictures:

}
I have given up all hope, so I turned to oneplus customer support, who advised me to install OOS 5.0, and see if that makes any difference, but as unsurprising as it may be, it does not. I'm even getting worse battery drainage on OOS than on RR.
Since the problem persists through kernel, os, and firmware versions, official and unofficial, all I can think of is it being a hardware related issue (mobo/battery malfunction?).
Do you guys have any idea as to what I should try to fix my device?
Thanks in advance,
Lada.

why not do a clean flash of oos 4.5.1/ oos5.0 has lots of bugs especially battery related. and also change your one plus 3T's battery and se if that helps. my frmd with one plus 3 had same prob like urs. we went to one plus care and asked them to format all install oos 4.1.7 and change the battery they did exactly as we said and he is happy now with his device working fine

I've flashed OOS 5.0 because I was advised to, and a friend of mine has the same setup as I do (3T with OOS 5.0 w/ Magisk), he gets 5-7 hours of SOT, whereas I still get about 2 hours.
I would've swapped out the battery already if I didn't have warranty. Since the issue isn't because of my actions, I'm hoping they'll fix my device under warranty.
Show us a picture of kernel wakelocks.
Make sure wifi always scanning and keep wifi on during sleep are both off.

Don't seem to have any screenshots from when I was still on RR, but this is what BBS and WLD tell me now on OOS:
Also, not sure how much information this one has, but "OS System" is usually the top battery consumer, with these details:
WiFi always scanning was most certainly turned off, WiFi on during sleep was on, but it never caused battery drain before.
First suggestion: The qcom_rx_wakelock is related to WiFi operation. Try disabling your WiFi for a few hours to see if the battery drain and excessive qcom_rx_wakelock issue is reduced.
We'll see where we go from there.

Did some Googling, and this may be Google's all holy knowledge of its users, but the first few pages that popped up were oneplus-related, and I found this thread, so I set my home network's IP address to static, and entered what address my router assigned my phone to.
I'll do a full charge before going to sleep, and going to leave WiFi off for the night, see if that indeed does reduce the battery drain.
If it does, I'll leave WiFi on for the next night, to see if the change of IP address helped at all.
I didn't change routers in years though, nor have I updated its firmware, so I find it extremely odd :thinking:

I had seen the router threads while checking into your issue, but I didn't want to pursue that path until we isolated that it was first a WiFi-related problem.

Yup, disabling WiFi basically reduced battery drain to 0% overnight, qcom_rx_wakelock is also nowhere to be found.
So now what? :/
Here's a crapload of screenshots:
I took these right after waking up:

Your logs look pretty similar to the ones I've taken over this time. I've got a replacement back cover on the way, I may just replace the battery as well and see if that maybe fixes things.

Well, tbh, it probably has nothing to do with the battery? I think it's either the WiFi module (if such a thing even exists, I'm not good at hardware related stuff), or something with the motherboard. If the battery itself would have issues, it would drain no matter if the WiFi is turned on or not.

Probably not, but I've seen bad batteries cause all types of having. Wonder if this issue is 3t specific, maybe something with the 821?

I think neither, some more Googling brought up posts from xiaomi's forums too.
If it were 3T specific, I think *a lot* more users would be complaining about it, so there would be an easier workaround, especially if it would be 821 specific, which tons of phones use.

@qbanlinxx - Did you test overnight with your battery fully charged and your Wifi disabled? Are you seeing a bunch of qcom_rx_wakelock wakelocks in Wakelock Detector? If "Yes" and "Yes" the chances of this being a bad battery are about zero, and maybe less than that. If you are seeing the same stuff as Lada333, you should hold off throwing your money at a replacement battery, unless you really like wasting your money.

@Lada333 - Good to see an improvement! At least we know where part of your issue comes from.
So, one of the thoughts out there on the interwebs is that the excessive qcom_rx_wakelock issue is router-related and not phone related. Do you have another WiFi source that you can connect (maybe at work, or a family member) to and see if your phone has less wakelocks? What is the make & model of your WiFi router? If it is router related, we may have options available, such as installing Tomato or DD-WRT with better firmware.
Also, have you tried setting your OP3T to turn off WiFi when the screen is off and unplugged (Settings >> WiFi >> Gear >> Keep Wi-Fi on during sleep >> Only when plugged in)? It's not a full solution, but it can help you get through the day until we get you a better solution.
An app that gets good reviews is ForceDoze. I don't use it myself, but it may help for now.
I know that it would be a bit of a pain-in-the-rear, but I have religiously been running Sultanxda's fantastic ROMs for many years now. You might want to transition to his ROM. I haven't seen this problem on my OP3T at all, and I usually lose less than 1% per hour overnight. His support is great, with frequent updates.
Sultanxda's OP3T ROM is: here.
I'll keep looking for phone-side solutions, but let's keep checking your router to see if that is the point of pain.
Cheers,
¿GJ?

This might be just me recalling information falsely, but I think no matter if I'm connected to any network or not, as long as WiFi is turned on, I'm getting battery drain. I'll make my phone forget my home network for the night, and leave WiFi on, see if it's actually the case or not. I live in Hungary, and I was given this horrible ****ing router/modem combo for my internet subscription, which is barely researchable, only results I could find were people raging on Hungarian forums of how **** it is, either way, I've had this same router (with no software updates whatsoever) long before I bought this phone, so I doubt anything has changed there at all. I believe I looked into it a while ago, and since it's basically only given out to Hungarian people, there's no custom software to run on it unfortunately (though if possible, I might look into getting a different modem/router, this one has always been a pain in the ass to use).
I have wifi always on turned off for now, but even that doesn't seem to be helping much, I just manually switched on wifi during the day when I needed it.
The app you linked is just an on-demand wakelock generator, I'm not sure what you meant by that?
Surely, I can give sultan's ROM a shot, see if it makes a difference, however a complete and full solution for me would be if I could keep using RR.
Can't tell you how grateful I am for your detailed responses, thanks for all your time and effort!
Oops, you're right - I chose the wrong app from my past installation history. App link has been corrected to ForceDoze, which you may want to include with the WiFi setting I suggested.
Regarding your router/modem situation, you may have had an update pushed by your internet provider without your knowledge. I know my ISP updates my personally purchased modem every now and then with their own firmware.
The modem/router combo may not be an issue for you (other than the cost of course). If you can get into the basic settings page of your modem/router (usually at http://192.168.0.1, or http://192.168.1.1, or http://192.168.100.1, but it could be elsewhere), you can disable the WiFi radio of the router, and just use the device as a modem and simple router. You can then take the Ethernet output of the router to a real WiFi router for some modern technology.

Some battery threads:
http://forum.xda-developers.com/showthread.php?t=978269
http://forum.xda-developers.com/showthread.php?t=1004760
updated tl;dr for most of you lately:
Your problem is probably that you flashed a new ROM or kernel recently, which causes battery stats to be very inaccurate. The most common symptom is that suddenly the battery drains like crazy, when before it just dripped. The opposite can also happen - you flash a new ROM and it seems like the best battery life ever. Until it suddenly jumps from 60 down to 10. This can happen even if you erased stats after flashing. You need a few days with your new ROM first, then you should see what your battery usage is really like. Do full charge cycles to speed up this process. (Bump charge, erase stats, drain, charge, don't bump charge or erase stats anymore, drain, charge, drain, charge, etc.) Simply put: you cannot judge battery performance after flashing a ROM. Often it can be a week or more before battery performance and battery level reporting becomes stable.[/tl;dr]
Every time a chef makes a new ROM available, or even among those using stock OS, there seems to be wildly inconsistent feedback on battery life. Many report catastrophic battery drain, while others using the same hardware/firmware/kernel/ROM say it's the best battery life they've ever gotten.
It would seem that a battery can run away on you for a variety of reasons, and flashing back, or returning to the store, doesn't have to be the first thing you do to fix it. This thread is to consolidate many of the complaints around xda about sudden battery drain, and discuss proven (or superstitious) fixes for it. This is not another discussion on tips and tweaks to extend battery life. There's a good wiki on that already. This is specifically about when you experience an unexplained dramatic increase in how fast your battery is draining, and the usual tweaks aren't having any effect.
And, in some cases, if you are experiencing battery drain associated with one of the "more interesting" issues below, you might be experiencing lag for the same reason. Please attempt all of the below to the best of your ability before making a post about battery drain or lag with a particular ROM or kernel.
We'll start with the simple.
Don't rule out your imagination or neurotic behavior as the main problem.
I hate to open with a "shut-up-noob," but this one is real. I know I've almost fallen victim to the disease of "let me turn on the screen just one more time to check the battery %." Or hours of "man this new lagfix is great watch how fast I can swipe screens and load apps over and over!" Both of which, obviously, result in more battery usage. Then there's also the case where you just installed a numerical battery meter for the first time, and watching it tick down is weighing on your psyche much harder than the previous, barely noticeable movement of the bar and making you think your battery is draining wildly. Which then can also then lead back to disease #1 in a vicious cycle of psychosomatic battery abuse.
It may just be the battery itself. Some are reporting an apparent quality control problem with the batteries. You might get a great one, or if nothing below helps you then maybe you got a dud. I can't help much there. Try reporting the problem to AT&T or Samsung. I hear AT&T is a lot better to deal with.
Check the basic battery usage stats. Settings -> About Phone -> Battery Use. This won't necessarily tell you a whole lot, it isn't always accurate, but it can give you an idea of what the system thinks is using most of the battery. Such as whether it's playing with the screen too much, or making a lot of phone calls, etc. Keep in mind... I'm pretty sure that these stats are only based on the time period listed at the top of the screen. A lot of people get confused when it shows the display using 90% of the battery. But if that's only based on the 30 seconds since you unhooked the charger, then it isn't all that confusing anymore.
Be wary of the "battery full" status. I have repeatedly found, at least in leaked 2.2 ROMs, that this alert actually goes off long before the battery is finished charging. This bug often continues even after you've done all of the other various tricks and tweaks and recalibrations. It says "100" and that the battery is full and to disconnect the charger, but when you disconnect, it instantly drops into the low 90s and drains quickly from there. Rather, if you ignore the alert and keep charging for considerably longer, it will actually be at 100 when you disconnect, and will drain slowly.

I'm quoting out the above, since I can't find the strikethrough tag. With new accurate battery mods, this isn't true anymore. Your battery doesn't need to go to 100%. It will be high-90s when you unplug, this is normal.
Drain and charge.
Sometimes the battery meter will seem to plummet, but then sit at <10 for hours before it finally shuts off. Giving a full drain may help calibrate where the "zero" really is. Run a long video, or just leave the camera up, until it shuts itself off. Then charge it back to 100%.
The bump charge (now commonly referred to as recalibrating).
Maybe your phone forgot where zero really is, or maybe he forgot where 100 really is. Here's the bump charge. Read carefully; I did it wrong for a while before I got it right. Charge the phone to 100% while it's on. As soon as it hits 100%, unplug the charger and power off. Now plug in the charger while the phone is off, and charge to 100 again. As soon as it hits 100, unplug the charger and power on. Wait until it boots completely, then don't charge this time, just power right back off. Now charge to 100 one more time with the power off. Power on and you are bump charged. Many also consider a stats wipe to be essential to this process as well. See below.
See joeybear's post (linked below) for more info on bum charges and battery stats, such as different procedures for CyanogenMod.
Erasing the battery stats (for you rooters/flashers)
Sometimes you just want your phone to forget everything he thinks he knows about his battery, and re-learn it from scratch. Your phone maintains a file with statistics on battery usage, which in turn is used to help calculate battery life at any given time. Sometimes, especially if you've been playing with ROMs, kernels, and lagfixes, the stats in the file just aren't applicable anymore to how the hardware is being used, so you get crazy battery drain.
Clockwork Recovery has a simple function to wipe the battery stats. If you can't run Clockwork, use ADB or a terminal emulator (search the market) to delete that battery stats file located at /data/system/batterystats.bin. The link at the bottom to joeybear's thread has a little more info.
The general idea is to start by trying the above - make sure it isn't your own fault or maybe just a bad battery, then drain, bump charge, and wipe stats - in that order.
There are lots of ideas about what may or may not happen when you experiment with the above. Wiping battery stats after a ROM flash that already wiped them for you is at least redundant and may even contribute to a battery drain problem. Some say you should wipe first and then drain and bump charge. Be careful about wiping stats and bump charging too much, though. Over-charging your battery will hasten its demise.
HOWEVER, if you're like I was when I first started this thread, you've seen the above recommended many times, and none of it has ever helped you one bit with an actual sudden battery drain problem.
Now for more interesting work.
Occam's razor. The simplest answer is the most likely. Battery appear to be suddenly draining faster? Well, it could be that you need to retrain your phone (or your mind) by using the procedures above. It could be that your battery suddenly went bad. A more simple answer is that something is draining your battery. Something is abusing your CPU, your memory, or your network interfaces. Try to find out what, or at least stop it even if you don't find out what. Simply looking at the stock report of battery usage isn't likely to tell you everything you need to know, though.
If you've recently flashed something, try your flash again, and this time be more aggressive. Make sure you turn off any lagfixes you've installed beforehand. Make sure you've got the most charge you possible can before flashing (see above - you want a true 100% charge immediately before flashing). Take the plunge and opt for repartitioning, data wiping, formatting, master clearing, or any other options you may have to start with a clean slate with the new ROM. Even flash stock first. Pay close attention to battery usage as you re-install apps and get your phone set up again. It may be one app in particular that was responsible.
Uninstall all task killers. Yes, uninstall. I know task killers are supposedly battery savers, but 99% of you (including me) don't know what we're doing when we get our hands on a good task killer. It is very possible you've got one service that is constantly trying to load and call home, and another that is constantly auto-killing it. If you really want to include task killing as part of your phone maintenance and battery tweaking processes, then download an app that is specifically designed and configured just for battery efficiency, not a general-purpose task killer that will allow you to hose up your Android system.
Check your background syncs. Experiment with turning them off, one at a time, and see if there's improvement. The app may have gotten confused after all your flashing and is doing something crazy as it syncs. If you isolate one that makes a difference, reinstall it or try living without it.
Live wallpapers. They actually improve your battery life, no lie. Ok, actually that is a lie. Some of them look awesome, but many users, myself included, experience a significant increase in battery drain when there's a fancy full-screen animation running non-stop on the phone. Try getting rid of them and see. There are some nice, simple, dark wallpapers that don't animate but are still pretty enough to impress the ladies at the bridge club. Live wallpapers can also create some majorly noticeable lag in your other apps, too.
Install OSMonitor. Set it to sort process by load, descending order. There shouldn't be much in the list, the OSmonitor app itself should show up near the top, at around 20%. Other apps should be in a 0% wait state or occasionally grabbing a few %. If you recognize an app sitting consistently at 50%+, that could be your problem. Make sure you know what it is first (not a critical system service) and try uninstalling it.
Is kswapd0 taking a lot of CPU? This is the memory swap / page file process. It's normal for it to be grabbing little chunks of CPU here and there, but if it's sitting at a high %, or jumping in frequently to a high %, then something's going on with your memory cache. Unistall your lagfix and try a different one. If you aren't using a lagfix, get OCLF and use it to install EXT2 and then OCLF V2+. Despite the changelogs and debates that claim otherwise, several have found OCLF to be very useful after flashing to any Froyo ROM (unless that ROM already includes a lagfix such as voodoo or stumpy's). If none of that works, your kernel may be the problem. Swap it or go back to stock.
Look at data/network usage. If you have a router or other device on your home wireless network that can give you some info, try that. Does your phone appear to be trying to send or receive an unusually high number of packets/data even when you're not doing anything with it? Also, while off wifi, watch the little green and red data icon in you notification bar (the 3G / E icon). Are they spasming green and red constantly every 2 or 3 seconds, even when you don't think you're doing much data transfer?
OSMonitor can also again be your friend here. Under "Network" you can expand each interface and look at live data transfer #s. Does one of them seem to be really active despite you not doing anything in particular with your phone right now?
If you have any of these signs of heavy data usage, go back to OSMonitor and look at Connections. Turn on DNS reverse lookups in settings. Turn on some whois. Ignore any loopback (127.0.0.1) and likely you can ignore the 1e100.com stuff, that's just Google (get it? 1x10^100). Are there any other established connections? Does the reverse lookup (the domain name) indicate what application might have the connection open? For example, if it's weather.com, that might be a Weather Channel widget or app. That one was responsible for destroying my battery one time. Use whois and similar tools in OSMonitor and on the Internet to help you figure out what your phone is connecting to. If you've got heavy data usage and an app or apps have open connections, uninstall / reinstall those apps and see if the battery drain stops.
Under-volting. Xan's Voltage Control App. There's a lot more of this going around now that there are several overclocking and undervolting kernels available. There isn't a whole lot to be said here. Different CPU clock steps can be individually adjusted to pull a little less juice from the battery. Make sure you keep them as temporary settings and do not "set on boot" until you're sure you've got a stable configuration. If you set something to a level your phone can't handle and script-save it for booting, you might not be able to boot again. Anyway, under-volting will not suddenly revolutionize your battery performance, but it can help.
Also, switching UV settings can significantly affect your battery meter after reboot. If you've recently switched UV settings and rebooted, your battery meter might suddenly show 20% more or less batterly life than before. This is simply what the meter thinks to be the case, obviously your battery did not just jump 20%.
Backlight notifications. I don't have hard data to back it up yet, but I've noticed that when a backlight notification is active, my battery starts racing to zero.
Cyanogenmod. It's available on Captivate now. It isn't stable/supported. It has a lot of debug code enabled. That means it uses more battery than it will someday when it's stable RC and debug code is commented out.
I've successfully used all of the "interesting steps" above in different cases where I had sudden battery drain and the basic steps didn't fix it. Anyone else have success with these? Any other tactics to share? Please post.
Thanks to joeybear23 for good info on recalibrating the battery.
Great info on the battery.

Ok, maybe your batteries are actually no good. Many have found theirs to be faulty and that after replacing them all is well again.
I just got a spare and the new one is great!
Maybe a batch of samsung batteries has problems and they begin to lose charge quite quickly after they have been in use a month or 2 (Or they get confused after multiple Flash's of ROMS .
Basically, I bought a cheap aftermarket battery as a spare and decided to try it in my phone today. I have made several calls and installed some apps and have played around with the phone as per normal. After 7 hours it is at 53%. MUCH better than before. With old battery it would be at 10-15% after a day at work.
Only thing different is I did install the lag fix over the Beta 5.5 to see if it helps speed.
Is it the battery or the phones software causing the problem??? Well if they have a chip in them maybe it IS the battery...???
Great read there! I haven't really been having any problems with battery life lately, but installed OS Monitor anyway just to see what was running. Nothing too out of the ordinary, as everything seems as you say it should be. OS Monitor is up there at 15-20%, android system is at another 8-10%, and system/bin/sensorserver_yamaha is running at anywhere from 7-16%. I assume this is the sensor that monitors what position my phone is in. Other than that, I don't see any other process taking more than a small slice of CPU or so from time to time.
I have done all of the suggestions before; bump charging, draining, and wiping stats, but I also feel that there may be differences since I am using a few different batteries. If I seem to get amazing battery life from a battery after wiping the stats and then using it til it dies, when I put in the next battery, it may work differently, thus screwing with the stats yet again. I have tried to not be as worried about battery life, especially since I have multiple batteries, but it's still something of interest to me.
I'll be subscribing to this thread, and look forward to reading some other users' thoughts/experiences with their batteries.
Scott -
In my own experience, putting lagfix on cog 5.5 has a huge beneficial effect on battery drain. I'm not sure yet but I believe the Unhelpful kernel uses a lot of cpu trying to manage swap unless you put an ext cache on it.
However, it's also true that you can great great life out of a new battery for the first 2 or 3 charge cycles. But a battery suddenly draining faster than normal is probably something your phone system is doing and not a bad battery.

Also, Demented, don't forget to look at antennae/network abuse, not just CPU. I once had a malfunctioning weather widget that wasn't using much CPU but was going berserk on my 3G and sucking batt juice so fast that you could hear the battery whimpering a little bit.

Some of the stuff there is valid; not sure I agree with using the task killer or the advice about leaving "Use Wireless Networks" on and GPS off. I leave both off, and when I want GPS access I turn on the GPS from the power control widget.There's no need for your Wi-Fi adapter to always be searching for networks and associating with Skyhook, etc.
Regarding leaving Wi-Fi on rather than 3G, it does make sense when you are using data. However, if the phone is idle, I doubt leaving the Wi-Fi card enabled will actually save battery life, as it will have to maintain connection with the access point (see your Wi-Fi sleep settings). I think a few short bursts of 3G download/upload when syncing, etc. will be less drain on the battery than leaving Wi-Fi enabled just for those small amounts of data that will be used when syncing. But, if you always want to be ready to browse, or do a lot of DL/UL at a moment's notice, I could see how keeping it on would be justified.
If manually syncing is acceptable to you, then by all means turn off the background data and auto syncing... personally I feel like the phone is really being limited and you have to balance utility and battery life, so I leave those options enabled.
Just some thoughts, if anyone can correct me on anything, I'm eager to learn.

I'm not really sure what you mean by that? There is no swap in use unless you add your own script to mount a swapfile.

Sorry I wasn't being very accurately descriptive there of what I've seen. I rarely know for certain what caused or fixed a battery drain issue. Thanks for calling me out on this one, because going back over my history on this it looks like I was largely mistaken in thinking your kernel had much to do with it. One of my worst experiences with battery drain, it seemed that I had some apps/widgets that just didn't work well after the kernel swap, but Cog also made some non-specific references at that time to battery issues with the kernel and that stuck in my head. Another time with a Cog ROM I believe I may have misread the changelog and I was under the impression that I was on a new Unhelpful kernel, when I wasn't. Looks like that time it was actually a stock kernel partly responsible for the drain, which makes sense. Was I totally confused thinking Cog 2.2B5.5 uses an Unhelpful kernel?
As for what I was seeing (thinking now it was actually not on your kernel), kswapd0 was going berserk on my CPU. All I know is that is generally the name of kswapd0 is referring to virtual memory management, and putting OCLF on fixed it.
Well, vm also allows clean pages that are backed by files to be "swapped" out by freeing them, without using a swapfile, because the data already exists in storage.
A release or two ago I had some battery drain issues that were resolved by reverting some config changes.
Cognition 2.2 can't use any of my kernels, the froyo leak uses a different kernel version, and we don't have Samsung's modified sources yet.

Right, which makes sense when I look back over my flashing history. DG had two versions in one changelog, and a line about re-adding your kernel to Cog 2.1.7 slipped in between some changelogs about Cog 2.2 beta releases. So I originally misread and figured that you'd somehow made a 2.2 kernel. It started draining my battery like crazy, which is exactly what happened the previous time I used an Unhelpful kernel (though again probably unrelated or only somewhat related to the kernel), and so I figured I was on to something. I was wrong. My b.
The issue that still remains is that I believe many people who flash to Cog 2.2.B5.5 (and perhaps 6), without master clearing and stocking first, end up with some odd behavior with whatever kswapd0 does (e.g., odd behavior like constantly using up to 90% of CPU for no dang reason). This is probably a cause, or the cause, of the Lagfixgate scandal and maybe Sudden Rapid Battery Drain Syndrome. And for whatever reason, OCLF fixes it.
I master-cleared and flashed 2.1 stock and then Cog 2.2B6, and kswapd0 and lag are no longer an issue even without OCLF. Battery is too soon to tell, though. Seems to be fairly normal, but not as good as some of what I used to see on Eclair with various other kernels swapped in.
Great resource here. Please keep updating! Subscribed...
Although you can't see it so well in the vid, the lagfix demo I captured also demonstrated a couple of points of battery life improvement.

With any of the 2.2 builds my cpu runs at constant 10%. We know its beta but worth looking into. Only info i have seen on my phone was android system. So im unsure what it is. Havent tore into it yet. But that was all stock with no apps installed. Even cog 6 i have the same cpu readings. So who knows.

Guess its not really 10% but up there
Just a tip. I was using latitude and wasnt getting the normal battery life i usually was when i wasnt using it.
I didnt know it was effecting it though cause you dont see it in task manager but you will in applications/running services. Anyways i signed out of latitude and battery life is back to normal.
It wont be remarkably better but it was noticeable to me. Just a tip.

How does that compare to when you're on earlier (eclair) builds? I expect there'd always be a little utilization going on.
Hello xda-developers,
I'm having some trouble with my lg optimus 4x hd, the battery is mostly drained by the android system, which doesn't normally use a lot of battery.

I'm not sure. This is more like an o4x issue. I had the same: battery usage is 60% Android system, followed by mobile stand by 18% and some more minor percentages.
My Samsung uses most power by use of the display.
So 60% is far too much.
I am trying to find out what I can achieve by rooting and freezing some apps and/or using Greenify. What I hear is that upgrading to Jelly bean causes more trouble.
Airplane mode - causes lots of baseband_xmm_power wakeups
WiFi on when not connected to router - same
Use e.g Tasker to turn on wi-fi when screen is on, and turn off when screen is off. Right now, I have baseband_xmm_power usage at 0.8%, after 16 hours of on time and about 1h 10min screen on. Try experimenting a little more! Using the WiFi>advanced>Keep Wi-Fi on during sleep is not recommended, as it causes a lot of wake locks... :laugh:
I experimented a lot and since yesterday I managed to use less than 10% while asleep. Before that it used 30% or more during the night (about 8 hours).
After disabling a number of processes I can see now that the Android system uses only 12% in stead of 60. The Android Operatingsystem even 2% only. On top is now Mobile Stand-by (42%) en Inactive phone (39%).
This is very satisfying. I did not really documented what I disabled, but now I can root my phone in order to disable things one by one permanently. Because I guess that most of the processes that I disabled will probably be active after rebooting the o4x.

@xtribas if he's still on 4.0.3 stock, this might be a different issue -- same as mine: 80% of the time a full wakelock held by "com.android.providers.settings" -- nothing seen of baseband_xmm here (though I used a different tool than BBS to check -- will switch-over to BBS next for verification).
@Mauvan mind to tell us what you changed, and how your progress / long-time effects are? As we two seem to share a similar problem, I would be very much interested in your details!

on ICS the baseband wakelock is not present... even so... revert to ICS is not an option for me...
As I did not update yet (stock JB is no option for me, as some of my apps wouldn't work well anymore -- e.g. LBE, and no, the localized Chinese "Master" is no option for me either), there's nothing to revert. But as I wrote: I clearly can see the same issue Mauvan has reported, and am just trying to figure out what that should be. No idea why some "provider settings" should need a "full wakelock" for 12+ hours between ~8am and ~21pm. Funny thing, though: deep sleep is more than the 1h difference to-be-expected, but something > 6h.
@Izzysoft: I upgraded a few days ago to JB and disabled a dozen of programs like Application Manager, Cell Broadcast, some widgets (contacts, memo etc.), Picasa uploader and stuff like that, which I don'use or force Stopping some apps (no permanent solution though).
All these tricks help a little. Yesterday the battery was almost empty after a little more than 15 hours. Not much, because it was not a day of extensive use of my phone.
At this moment I see that my battery load is 72% after 5 hours en 24 minutes.
I'll continue reading forums like this and decide this weekend if it would help to root my phone and look for more permanent solutions. I am not considering Cyanogenmod's rom because there's still no stable version. I've seen great performance improvement of this rom on galaxy s plus, so there is hope.
@Mauvan so you don't remember what you did back on 4.0.3 -- or did you start this thread when already being on JB?
Seeing your numbers, I cannot complain: ~70% is what my 4X goes back on the dock at night, after ~15..16h. Estimated battery time altogether is around 2 days for me (and yes, my device is rooted and I disabled/froze a lot of that stock crap, bloatware and mafia-ware -- e.g. the RemoteCall stuff which does not accept a "No" as answer). Still room for improvement: If I can get hold of that stupid "com.android.providers.settings" WakeLock, I should end up with 80%+ and an overall estimated battery time of 3d+, nice for a weekend in the hills

No, when I started this thread I still had ICS. However, those statistics where too optimistic. After a few hours it went down & down & down. That's why I tried JB. Seems smoother, but drains the same.
Now it's my turn to ask what crap you disabled/froze etc. and what additional apps do you use to achieve that. I would be Very Very happy if my battery time should be, let's say, 24 hours at least.
As not everything is freeze-able from Settings->Apps, I used the friendly Titanium Backup (one of the first paid Android apps I aquired, and never regret) for the remains:
Chrome
E-Mail (believe it or not: even unconfigured it consumed battery by permanently trying to do some Exchange-Stuff!)
Email-Widget
Stock News
Google Play Books
Google Play Movies
Google+
Google Bookmarks Sync (just now, as they ran their sync though I unchecked it in Account & Sync)
LG On-Screen Phone
LGSetupWizard
Live Wallpaper Picker
Maps (using Titaniums freeze/unfreeze widget on my homescreen: unfreeze+start on demand with a single tap, then freeze again with another tap. Must not run in background 24/7/365 when only needed 2-3 times a year
PC Suite Service
PC Suite UI
Remote support service
RemoteCall Service (Mafia! That's the one which did not accept a "No")
Social Networks
Android Live Wallpaper
Today Widget
SmartWorld
World Time
After that, installed Apex Launcher -- and like my phone. Except for that minor juice-sucker
thumbs up! (except I need exchange for workthings)
And did you do anything with the LG-loggings and MLT stuff (hidden menu + apk)?
HiddenMenu I just used to peak into what's available, but did not actually change anything. What I'd like to know is about the LocMgr* stuff: Name suggests a "location service". I couldn't find any information on what it really does (as LocationService usually is included with the Google Apps, this looks like a dupe to me), so I didn't dare to freeze the two. Any idea what it could be about? Or even a reference on what it really is about?
No I'm not sure what it all means and I do not like to experiment in those settings. I've read some threads about the MLT like this one and that one.
In the mean time I just rooted my JB and freezed a bunch of apps. I'll let you know the improvements (I hope!!).
I hope for both (improvements and report)
EDIT: Wow, thanks for the Linx! Read that about MLT:
I just disabled it.. lost the weird battery drain from "Android System" that I've been having lately..
Click to expand...
Click to collapse
Looks like there is my culprit, huh? I just disabled MLT -- let's see how it goes. So now, we both wait for the report of each other LOL
so far so bad
disappointing, because the first night it should be in deep sleep. But instead it consumed 35% in 9 hours. Annoying issue seems to be Cell Standby, responsible for 44% of this drain. Famous wakelock baseband_xmm_power (says BetterBatteryStats).
What I figured out is that there was still one process looking for my location. Wifi disabled in sleepmode, it tried to find access to 3g, but in my house on that place there's not enough coverage (no signal during 56% of total uptime). Might be the age of my sim card? Dunno.
This afternoon I freezed almost all apps like in this link.
Tomorrow I hope to know more.
Edit (17th May):
I rooted my O4X, I installed a root browser, Titanium Backup, SuperSU, BetterBatteryStats.
I watched and monitored. Even tested Tasker (to reduce Cell Standby wake locks). I got a new sim card to replace my (very) old one.
Yes, it improved, but too little. Last night, after so many freezes in Titanium, O4X lost 10% in 8 hours.... doing nothing.
I'm beginning to regret buying this P880. It could be a bad battery, but I doubt it. Too many issues here and elsewhere on the internet about the battery drain.
Also looked at CyanogenMod experiences. This rom gives some people issues like these.
Trade it for an S II plus?
I love pretty much everything about this phone and can't imagine it being much better. One of the reasons I bought it was for the famed battery life. Most blogs and battery tests put it at just over the Z3 and one of the longest lasting phones out there.
However, that hasn't been my experience. I'm an Android veteran and I know how to look for battery drains and what generally causes them. I'm losing a lot of battery at idle and there doesn't seem to be any reason. Nothing shows up in the battery stats. I even tried stamina mode and the results were worse. I lost 20% over 11 hours without even touching the phone. It just sat there and lost 1/5th of the battery. Not quite 2%/hr, I know, but still significant for a phone in stamina mode and not being used.
The only thing that shows up in the battery stats are the usual suspects: Android OS and Android System. I don't have a weak LTE signal or anything.
So, I'm wondering if anyone else is experiencing fairly significant battery drain, especially idle drain. My battery life isn't horrible, but it should be a whole lot better from what I was reading before I purchased the phone.
Apologies for asking obvious questions, but are things like wifi, mobile date, auto-sync, bluetooth and NFC toggled on or off? Are certain apps repeatedly appearing in the Consuming Apps list? I tend to make sure I swipe these away which has helped when I've had similar excessive battery drain, for me these are (for example) Reddit Sync and Google Docs. It is weird that they don't appear to be high in the battery usage % list though...

Wifi, mobile data, auto sync, and Bluetooth are on all the time, as they are on all of my smartphones. These are not the cause of the drain I'm experiencing. If you leave all of those off all the time, there's no point in having a smartphone. NFC is off.
As stated, there is nothing in the app drain listing to cause alarm. Nothing in the battery stats is telling me I have an issue, which is why I'm frustrated.
Fair point, though I personally toggle them on and off as needed.
How any apps do you have installed over and above those bundled? I'd try uninstalling as much as possible then reinstalling then one by one. Or a less extreme option could be to clear cache in as many apps as you can, reboot and see if the drain stops.
I have everything enabled except Google Now and I lose about 0.2% per hour when idle. Also, I believe all the folks who are reporting battery life of 2 days with 6 hours SoT must be having very low idle drain.
So greyhulk I think your experience is not the norm, but unfortunately don't know how to help. Post up some screenshots of your battery stats.

When you look a the battery History details, do you see a lot of awake time? Also look at the top 3 or 4 items in Battery usage individually, do they show high amounts of Keep awake time while the phone is idle? A wakelock or poor cell signal are the two main causes of high idle battery drain.

It's definitely not poor signal. There is a bit of wake time, but the top 3 items are screen, android OS, and Android system. The wake time on those is not significant, either.

I'm about the same. I'm getting on average 7 hours on screen daily with everything on, no stamina mode, over 70% brightness. I left my phone unplugged for the first time overnight and it drained a whopping 1%! I've had the phone for over 2 weeks now.

Sorry to hear about your battery issues, but as mentioned, that's not the norm. Not sure how much help I can be, but I can tell you your Android System and OS percentages are about 2-3 times higher than mine so that seems related to the drain, but tracking down the culprit will be tricky. Have you considered factory resetting?
---------- Post added at 06:21 AM ---------- Previous post was at 06:16 AM ----------
Here's are a couple screenshots for comparison:
when Android OS and/or Android System drain more than cell standby and phone idle you can rest assured that an app or service is draining your battery.
Many things can be disguised as Android System (/OS). It could be google now, location services, syncing of google drive, browser sync or an app running it's own service etc.
Android system and Android OS always drain 2-5% of a battery on all of my devices. However I turn on wi-fi and other stuff only when needed. Plus I have all the google services, google voice and account sync disabled.
But I wasn't happy with the battery life on my Z3c also. Cell standby, phone idle and 1-2 ours of screen time drained the battery almost in 24 ours. Maybe it was one-time occasion (I haven't had much time to test it since the phone is new), but I starting to have a bad feeling

That seems highly abnormal, I leave wifi, mobile data, and GPS on at all times, with numerous accounts syncing, yet battery life has been superb for me and many others.
It's been a few hours since I posted that screenshot from my previous comment, but my battery has dropped a mere 2% to 35% and my on screen is now at 5h20m. That's the drainage I've been typically experiencing with daily heavy usage.

Yep, Android OS and system are about twice what they should be, so that's probably at least part of the cause....

I'm not going to factory reset a phone a few days after I took it out of the box and set it up. That's ludicrous. It's set up exactly the same as several of my previous Android devices, none of which had this kind of drain.

I am seeing the same performance as you. Honestly, at the end of the day I still think the battery life is pretty solid, but not up to the legendary levels others are seeing.
Some guy said he left his phone sitting there overnight and saw a 1% drop? That is insane.
As an aside, how are you showing the Android L on screen buttons?

Factory reset is the lazy answer and should only be a last resort, especially when the device had only been active for a few days.
That would be like telling someone to format their computer every time it slows down a little.

A factory reset at the very start is the best time to do it, rather than wait weeks, months from now when it would really be cumbersome, but anyway, you do whatever you think will help. I already tried offering help and you were pretty rude about it so I'm done.

You're kidding, right? Two days out of the box, I have every account set up, all of my music downloaded, all of my apps set up, and my interface tweaked to be the way I want it. It's not any easier now than it will be three months from now. There's also the fact that the device shouldn't run this way out of the box.
Whenever there's a battery thread or a person asking for help on this forum because they have a weird drain, there are two predictable responses that will be offered almost immediately:
Turn everything off - Yes, if you toggle everything off, you'll get good battery life, but then why even have a smartphone? Most modern smartphones are capable of getting decent battery life with all radios on all the time. This is not a solution.
Factory reset - I work in I.T. If I told someone to wipe their computer every time they reported an issue, I'd be out of a job. That should be an absolute last resort. I could see it on a phone that you'd been using for months that suddenly had battery issues and you couldn't figure out what the cause was, but a phone that has been set up less than a week? Please.
These kind of offered solutions aren't helpful, yet they're always the first ones offered. It has been this way since I took it out of the box on day one. So, it either it doesn't like one of the apps I installed from the get go, or it has another issue, or is defective. I mainly posted this thread to see if others were having my experience and a few have confirmed that they are.
So, I'm sorry if you're butt hurt, but I certainly wasn't trying to be rude. I was just disregarding a solution that I predicted someone would offer that is not an option at this point (and really shouldn't be). Anyway, thanks for trying, I guess. Just please be aware that if someone comes here looking for help, they're doing so because they don't WANT to wipe their phone or turn off all of its features. They're looking for an alternative solution. Even newbies know enough to wipe their phone when things aren't working right and it's the last thing they want to hear if they ask for assistance.

Actually without having the phone in hand there is little anyone can do to tell you what is draining the battery, the suggestions given are typical of tech support help if standard things don't work. So you can either take those suggestions or do more research since you have the phone in hand and find the problem. Based on the information given there really is no magic answer to help you.
This is not another, I love this phone BUT the battery is too small.
Currently there is a massive bug affecting the T-Mobile (possibly others) Galaxy S6 (unconfirmed on edge)
Symptoms
Massive Battery Drain while Idle
Cellular Standby top Usage in Battery Stats
Random WiFi issues
Self Diagnosis
Go into Battery
Tap Cellular Standby and remember the "Total Connection Time"
Go back to "Battery" and hit refresh
Check Connection Time again
If the time increases but you are NOT using any applications, on the phone or downloading you are affected by this bug.
Fixes
Turn WiFi calling OFF
Disable VoLTE (VoLTE toggle is in the Phone App/More/VoLTE.)
Update - Turning off WiFi Calling along with disabling VOLTE appears to have patched this issue for now. You can still use WiFi like normal and turn that off and on and it shouldn't have any issues.
So lets discuss this, I have not been able to fix it. WiFi on or off, WiFi calling enabled or disabled nothing seems to correct the problem. Its as if the phone is ALWAYS on a call.
Edit- VoLTE seems to have corrected the issue somewhat. What I did is turned off VoLTE, Turned off WiFi calling and then turned WiFi off and back on. My Connection Time hasnt moved since. How long this patch lasts for, I don't know.
Mods - Please monitor this thread if you could for battery naysayers and complainers. We are out to diagnose and fix the problem, not complain about it.

Thanks for starting this thread. I have tried pretty much everything, including uninstalling/disabling most apps, turning off "keep awake" for what's left, etc. I just tried turning of VoLTE and I still lost about 2% in 15 minutes with my phone just sitting on the desk (no use). My next course of action is to try a wipe. I really don't want to take this phone back. I still think this is some sort of bug with 5.01. My Nexus 6 had battery life issues until 5.1 and now it's awesome.
Okay the VoLTE trick fixed my high cell standby drain.

I've used quite a few lollipop builds and I've noticed on just about all of them (including the s6) Google play services runs pretty high. Haven't had the phone long enough to accurately test, but I'd suggest for those seeing it run pretty high to completely disable auto update of apps. That should help limit its ability to wake up the phone.

I actually disabled wake for that app using App Ops. Nothing in Gsam or regular battery stars is telling me anything.
I just performed a wipe. If that doesn't do it, I give up.
Ok guys let me throw in my 2 cents.

that was yesterday usage. I had wifi on the whole time yesterday.
Now today usage wifi off since 100%, i have no ****ing idea why facebook is using that much, ive use it 10 mins at most.
Facebook is like a hydra when it comes to app permissions. It has the most permissions to your phone with few apps to rival it. Use an app that blocks particular functions you dont use in the facebook app (GPS, contacts, etc) and just install this (must be rooted) https://play.google.com/store/apps/details?id=com.findsdk.apppermission&hl=en
I realize it hasn't been a full days of use yet, but the Cell standby sums up the battery issue drain. I'd prefer to keep VoLTE on, and we should be able to without this being a problem. It was on, on my G3 and I didn't have such significant Cell standby battery drain. Any idea of another cause?
So, I finally caved in and wiped, even though I have had the device since Monday and battery has been bad all along. Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

For me, even without ever turning on my phone, it's syncing with breaking news apps, facebook, twitter, hangouts, gmail push, work email push, a couple online RPG games pushing me alerts and so on. My battery drain ironically isn't stemming from apps syncing and emails/alerts being pushed constantly throughout the day. It's the cell standby for me.
contributing factor?
http://forum.xda-developers.com/galaxy-s6/help/flash-lit-t3069039
Seems to be the cell standby for me too. Disabling WiFi calling and VoLTE has fixed it for now.
Is there a Samsung support channel where we could get this recognized? It seems really asinine that people are exchanging the handset for what is clearly a software defect.

VoLTE seems to be my problem for now. Disabled it. And fully charged it to 100% and its now at 75% and cell standby isn't even on the battery stats list.

So, I can't believe I'm saying this, but a factory reset totally resolved my battery issue. It was only 4 days old. I couldn't see how it could have possibly been fixed by that, but it was a last resort before returning it.
Now I have some pretty normal Battery life. I love this phone!

If you hadn't been a douche in your follow-up reply, I certainty would consider it.
Having this issue as well..after having a nice battery cycle of almost 5 hours sot I'm seeing the same thing in bbs, losing 6% an hour idle. Will try the fixes to see if it helps thanks guys
so im getting the edge on the 15th
should i factory reset it right when i get it ?
The only thing I did out off the box was take the OTA and root. Maybe the OTA set it off? I pretty much have the same apps installed now.

Somewhere earlier this year I started getting a 20% overnight battery drain. On a few nights it didn't drain, but its pretty consistent. I have tried everything listed on this forum..This drain is definitely not caused by any standard settings. I am really hoping somebody with insight into Oreo might have something new I could try. I know xda user Digisteve is going to showup and suggest more things, and that is also not going to work.
Things I've tried.
- using root to disable logd. (saw this as a process in BBS) Still drained.
- Disabling auto-sync of all accounts. Still drained.
- Turning on stamina mode at night. Still drained.
- Removed google play store, google play services framework, and all google aps - and replaced with alternative China app store. - Still drained. Not a play services problem.
- Turning off wifi, all wifi scanning, notifications of wifi networks etc. Still drained.
- Turning off mobile data and wifi - no connectivity at all. Still drained.
- Turned of location in all possible device settings,. Still drained.
- Rooted the device with Janjan method/kernal. Still drained.
- Flashed different regions. Including (Taiwan, my region, Malaysia, Germany, Swiss, HK). Still drained.
- Tried firmware verions , 179 , 205, 235, 270
- Deleting 3rd party apps. Still drained.
- Installing Gsam - checking for consuming apps. No apps listed as cause of the drain.
- Installed greenify. Tried as standard, non-rooted with adb permissions, and fully rooted. Still drained.
- Disabling various packages related to 'carrier services', qualcomm and rcs. Still drained.
- Debloated to the point that the phone had no google apps, no Xperia apps and removed tons of other apps, camera bloat, anon data, etc, all removed. Still drained.
- All built in apps replaced with a 3rd party app, including, sms, contacts, email, keyboard. Still drained.
- Installed Linage OS 15.1 Beta 5. Still drained.
- switched from 3G only to LTE only. both drained equally.. though I have worse single with LTE in my area.
I am hoping there is a better solution than throwing the phone away. Because I am pretty much at that point now. I have spent probably well over 120 hours trying to fix this, and I can't. Its at the point where I need to move on to a new device rather than waste more time.... but there are no small devices on the market now, and also no more classic xperia style devices on the market. Sony does not make the executive, classic 'Xperia' style I fell in love with anymore. I don't do round, heavy, huge phones. Very sad.
UPDATE - AUGUST 14
Now running the latest Customized German 270 firmware.
Still draining 20% per night. Check out the screen shots - clear to see I have almost no apps. No process can be seen as a battery hog in both Gsam and BBS. However Gsam screenshot shows evidence of CPU usage.
UPDATE - SEPTEMBER 13 - FOUND THE PROBLEM
Considering almost nobody had my issue, I assumed my phone must be a dud. Late August I bought a second XZ1 compact. The new phone worked for 1 day, and on the second day drained battery at 15% per night idle drain. Previously I had only tested the sim card by switching 3g,4g and disable mobile data, but never actually removing the sim from the phone. Last 2 nights I replaced my old sim with my gf sim of a different carrier. In the morning I had 99% battery remaining. No Drain!
I then downloaded an app these measures signal strength, and turns out where I sleep at night, there is is less reception. Its not noticeable just looking at the standard signal strength on your home screen, you need to check the more detailed strength in decibel millimps /dbm. I can still get good signal in most areas of my house, but the phone is having to use more power to keep the signal good. I can now reproduce the battery drain on demand. If I sleep with the phone near my bed, I get drain. But if I keep the phone in the living room, no drain. I found that connecting to wifi not a factor, since even if you use wifi for data, the phone was still holding open a connection the the cell tower.
This problem took me months, countless hours, and the expense of buying a completely new phone!!! Now I have 2 XZ1 compacts....arg.... but so happy its solved.
The important point is that if testing sim, good signal, or disabling mobile data, changing 3g 4g isn't enough. Your phone is using more power to maintain good signal.
Thank you to everyone who spend time trying to help me, digestive, proflyer, etc. Thank you guys.
At this point, I think it's highly likely you got yourself a lemon. Since you've already rooted the phone, warranty service is out of the question.
It boils down to two options:
1. Pay for a board replacement.
2. Try your luck with a brand new XZ1C. Buy it online so that you'll get the 7 days return perk (some online stores offer 10 days), keep it wrapped in its original packaging, handle with extreme care, and use it normally for a few days before your return window runs out. If you no longer get drains, congrats, and welcome to the club. If not, accept your fate, return it for a full refund, and give up on the XZ1C - understand that you weren't meant for each other and move on.
I had the same issue. Check this thread. Try that and report back.
https://forum.xda-developers.com/xp...ormal-battery-consumption-wifi-t3740495/page3
I know what you feel. I had this too, but mine went away and I only very rarely have this drain. But mine was always on Wifi. With Wifi off = no drain reported... never.
I investigated it for weeks without coming to a conclusion.
If you can, replace the phone with warranty. Worth a try. Right now in my opinion you have a hardware faulty device.
But i would say to wait for android 9. In my opinion it wont take ages to come. It will much likely come this year.

He still has drain even with WIfi Off, so that not the problem.
The only other thing I could suggest is having the battery replaced at a local repair shop. If you got a lemon battery but an otherwise fine phone, that could help.
How about remove your SIM card with wifi on for over night? Do you still experience the drain?

ONE WORK AROUND. If I reboot the phone, then unlock it so "android is starting" screen is complete. Then lock the phone, without doing anything else - The battery does not drain overnight. In light of this, what could be the solution? I know an app sounds logical, but I arlready checking my 3rd party apps, and none of them were the probably, an no battery app has ever listed an app as a drain.
Any technical or Dev person go any idea what that symptom points towards?

This does indeed sound like an app or a service gets stuck in an awkward way. You indicated in your first post that you use better battery stats, do you mind posting screenshots of the top of the summary, kernel wakelocks and partial wakelocks page (showing keeping awake services) as well as the bottom of the cpu states page (showing deep sleep time) "since unplugged" after a few hours of drain?
I have attached corresponding screenshots here for my xz1c (after more than 24 hours unplugged) as a reference (I have play services enabled and syncing both gmail and contacts and so on, no root though).

That doesnt make too much sense. Test it for at least one week before coming to conclusions.
Try this and let me know if it works
I had exactly the same issue
What i did (now magicaly works)
I did not have too many time so what I did was simple and I got a cheap replacement phone in the meantime
It seems to be beyond everything we tried
I conected the phone to the pc and did the fix with xperia companion, then I realized that everything was working as soon as I started to install the apps the problem came back, I installed a launcher (nova) and use it, drained the battery útil reach zero and fully charge it, then everything was working... Back to normal... I don't know how the issue was solved but hope it works for you
Sorry about my bad english xD

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.

Thanks didgetsteve. your probably right.... The GSAM and BBS stats were taken right after each other, maybe a gap of 2 mins. Play Services wasnt the issue though, as I tried my phone google free, and it still drained.

I agree with didgesteve, nothing jumps out by just looking at bbs (I am not familiar with gsam, so I cannot comment so much on that).
Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

I also had the drain that Dean has. But mine wasnt so agressive, I mean, some days it was there draining 30% battery over my sleep time (8hrs) and sometime it just behaved normally draining max 3% over sleep time. But still from time to time the drain come back wich is annoying as I cant let my phone with 30% battery left when im going to sleep, afraid the battery will be dead and the alarm wont wacke me up lol.
On my extensive tests, the drain only happened with wifi, but even deactivating all wifi related process (backups, syncs etc) the drain was sometimes there. Wifi wasnt the culprit with Dean, but on my tests: Wifi On = Sometimes big drain , Wifi Off = never drain.
I never managed to find the culprit of this damn drain and Im a software tester. Gsam did not show anything unusual at all. It was like Deans screenshot.
We discussed about this issue a lot here (https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8) but till this day we dont know whats triggering it.
Im curious how the phone will behave on this issue with android P.
@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?
i dont see nothing odd there

@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?

I'm sorry, but I don't think I have the knowledge to judge that. I would expect CPU usage to be low in deep sleep mode, but since the CPU is mostly sleeping, I guess any requested usage will queue up in a way that might look odd, so what you are seeing might be normal (but again, I don't actually know). I also believe that CPU power consumption is mostly related to the frequency state it is in, so deep sleep should mean low consumption (independent on cpu util %).
As I indicated in my previous post, I would sooner blame the radio chip or the battery than the CPU given your BBS screenshots.

Bro, Samsung is even worse when it comes to battery drain. Check out linus tech tips vid from a few days ago https://www.youtube.com/watch?v=n46s_iF_IV4&t=324s
My wifes side of the family all have Samsungs.... they are totally ****. The OS is bloated, ugly, laggy despite monster specs huge ram, snap 845, and battery nightmares on brand new phones exactly like in Linus's video. And there is a stupid "BIXBY BUTTON" on the phone which is a total nightmare. if your with Samsung, BIXBY will the with you, following you forever.
In other news, I replaced my Taiwan XZ1 compact with an Australian XZ1 Compact, and my drain is gone. I drained 2% last night.
There are so many build differences with the Taiwan and Australian build of the phone. Bigger microphone holes, slightly different proximity sensor design, and the plastic back is a rough matt black/gray in the AU versions, the TW version was a smoother shiny midnight black with a silver sparkle in the sun. The biggest difference was of course the battery drain.
