Battery Drain. Help!

I have experienced it a couple of times in the 8 months or so I have had my Captivate (Galaxy S). One time it was due to a rogue application that was using heaps of CPU. Using OS monitor I discovered that an app/process had a load running consistently up at 50% or more.
Uninstalled the app, problem solved. For months I was getting 48-60 hours out of a single charge, which was absolutely brilliant.
Now I have a new battery drain, and it's proving very difficult to find. Checking OS monitor didn't help. No app sticking out like dogs balls hogging CPU this time.
I tried the advice in this thread;
http://forum.xda-developers.com/showthread.php?t=937080(preview)
Gone through it from end to end, and the battery drain is still there. The thread tells me I should be using roughly 1% per hour while on standby. Current widget tells me I am using 1% about every 5-8 minutes, which gives me 8-12 hours of battery life.
I have gone back and uninstalled a heaps of apps I no longer use, as well as uninstalling apps that I installed around the start of the time I noticed battery drain began. No good.
Checked all my settings, even experimented with turning off background sync (which I dont think is the problem, as I had it on when I was getting 2+ days of battery life), no good.
Using Titanium Backup, I went through and began "freezing" a couple of apps at a time, thinking I could find the application causing it that way. I sorted my apps by install date and started going back in time 2 or 3 apps at a time. No good.
However, I think I may have found a clue...
The other day, I turned my phone onto Flight mode, I can't remember why now. Anyway, I realised a few hours later that I forgot to turn Flight mode off. Looked at my battery and noticed, it had hardly dropped at all! Weird. As far as I can tell, I have the phone set up the way I did when I had great battery life. In some cases, I have even tried doing things I did not do when battery life was good (turning off background data, wifi etc). I still can't pinpoint the problem.
Who else has experienced battery drain on Android? What did you do to combat it? It's just frustrating knowing what my phone and battery are capable of and not being able to achieve it!

I have has that a couple of times too. The only way I have found to make it stop when it starts is to do a reboot. Like you it doesn't appear to be any specific app, the os is just eating battery. Once I reboot its great again. Hope this helps

Well from a lot of different articles I have read, having a weak signal around you can cause a drain on the battery. The fact that the phone has to try to grab the signal harder than it should on top of getting then losing and having to re acquire the signal drains the battery.
I haven't done any tests myself but I find that I get great battery life when using the phone heavily while at home on the wifi network.

Nah it's not that easy unfortunately. It's a problem I have had for a couple of months now. There has been many reboots in that time, none have solved the drain.
The only thing that did was putting the phone into airplane mode, which then make it a nice-looking paperweight.

It may be that, but I don't think so. As I said, I had great battery life using this ROM, and in the same locations as I do now with terrible battery life. I haven't moved, I still use the phone where I did before.
Cheers for the responses anyway guys. I appreciate it.

Google maps is a known battery drain even if not using it thanks to latitude trying to determine where you are. I would try freezing or uninstalling Google maps.

Thank you so much! It appears you are right. I "froze" Maps using Titanium Backup, and for 40 minutes my battery has been steady at 24% while on standby. Brilliant! Usually in that time I would drop 3-5%.
Now, the next question. How do I stop it? Does this mean I can no longer use Maps? I don't even use Latitude, but I see no option to uninstall it anywhere. Everything in it is turned off.
Not sure how to proceed from here. I do use Maps from time to time and would like to keep them if I can.

Just un-freeze it when you need it.

One thing that I did was start resetting my phone right before bed to terminate all the programs that I used through out the day.

I have just upgraded to Serendipity 7, we'll see if that fixes the problem. If not, I may have to freeze Maps while not in use.

Well, after a battery calibration I am now getting 24-30 hours with moderate use. A long way from the 48-60 hours I used to get, but a lot better than the 10-12 hours of recent times. So I am half as well off as I was 3 months ago, but twice better off than I was a week ago.
Happy enough for now. Just wish I could pinpoint how I was getting that great battery life before!

[Q] Horrible battery on 4.3 sense roms?

Has anyone else had this problem? since upgrading to a 4.3 sense based rom (tried 3 different roms), my battery life has become horrible..i can barely get 2 hours of screen on time whereas i used to get 4+ on 4.2.2 roms.
i know alot of people have said that 4.3 improves battery, but it hasnt for me, its done the opposite.
also has anyone noticed strange heating up of the device? for example in asphalt 8 the device thats slightly hot and then cools down while playing. but in games like candy crush or zynga poker the device continuously gets hotter and hotter..
tips/fixes/stories anyone?

Mine has been really good. Like, 3-4 hours screen time good. When I'm on wifi (N only, G wifi drains a lot) my battery percent just flatlines on the graph until I pick up the phone again. Sounds like a rogue app since I don't have this issue. I run ARHD 20.1.

did you upgrade your firmware to 4.3 ( 3.09.401.1 ) also ?
met few guys who had the same problem and upgrading FW helped.
good luck

I'm running arhd 20.1 aswell. And I would LOVE to see that happen again, my battery drains around 10% overnight, and I'm a really late sleeper, so that means in 5 hours it's lost 10% on standby..and it's weird cause WiFi shuts off after about two hours,so I know that's not causing the problem.
App usage shows android system as the app using the most battery. When I check in the morning it shows android system and kernel to be the top two users.
Could it be a radio problem? I've seen a decrease in signal since ive upgraded to the 4A.17 radio from firmware 2.24.
I'm thinking about flashing the minsense Rom or even a ge rom and see if that helps the problem.
It doesn't seem to be a rogue app cause I actually have less apps then I did on 4.2.2, and none that are new..

I'm still running the current T-Mobile firmware, not 3.x. (I'm still S-ON with hboot 1.44) Thought that was worth noting.
Have you tried putting the phone on WCDMA/GSM auto instead? If your LTE signal is weak (or any kind of signal is weak in general) I see this phone's battery life usually take a nose dive. It has so far from my testing saved me a ton of battery to switch the phone manually into GSM only when I'm inside a building at work to get more bars, then switch back to LTE auto when I leave. Try leaving it on overnight on different radio settings, and with and without wifi. It could be a cell radio drain. And btw get GSAM battery monitor, the stock stats don't seem right to me. Android System being high in the HTC battery stats tells you nothing really from what I'm seeing so far.

the funny thing is i dont have data, since i get wifi wherever i am. i also think its a radio problem though, my gsm signal never seems to be full, and people constantly tell me on the phone that they cant hear me. so what im doing (right now) is flashing a ge rom, specifically sinless rom, then im going to flash the new ge radio, 4A.18, and see how that plays out, prolly going to flash a 4.3 kernel aswell so i can uc to 162mhz or whatever the value is.
i seriously believe its the radio+lack of kernel on 4.3 sense roms that are causing this problem for me. so once this is all done ill test it for the rest of the day and see how it goes. thanks so much for your help

If you don't use any apps, of course system uses the most.
You need to check for wakelocks. If you have unexpected battery drain, it's likely that the phone is not sleeping properly, i.e., being kept awake. Betterbatterystats, gsam, wakelock detector etc.
What was the change in signal attenuation, or are you just saying the the display bars are different?

i use apps, just nothing new compared to when i was on 4.2.2.
and no wakelocks according to gsam, i lost 20% overnight (7 hours)
i dont get what it is. i upgraded the radio to 4.19 now, but for the signal issues, it included lower bars, bad audio in calls, and random loss of wifi.
i removed basically every app, besides some essentials like facebook, whatsapp, and a few others.
i tried switching to an ge rom, but i just cant stay on it for too long, vanilla android is so plain compared to sense.
so the last thing i can think of, is a rom known for its battery life. not asking for a comparison, just your opinion in which rom gives the best battery on 4.3. any suggestions?

Charge your phone up all the way, put it in airplane mode, and unplug it for an hour then don't touch it. Then post your battery percentage. If it isn't still 100 or 99 then you have a more severe problem that actually relates to the battery itself.

Show us a graph of your signal strength from GSAM, and show us a screenshot with how many bars you have. At least you know now that the battery is definitely not shot. It is probably mobile data related...hmm did you ever try letting the phone sit with mobile data disabled as well? It should drain almost as minimally as airplane mode.

So wait, your signal is really good but your phone drains like crazy, and while you're on WiFi? Okay, what wifi router are you using and is it G or N and is it dual band?

its absurd i know..its already down to 93% with 9 minutes screen on..
and its a dual band router, im normally connected to the 2.4ghz band, and its with wireless ac, which the one supports. Which is weird cause i thought ac improved battery life..
edit: im an idiot, wireless ac only works on 5ghz bands, but that still doesnt explain the drain on wireless n..as my previous router was also wireless n

Have you tried 5 ghz N by forcing the router or your phone to operate only at N speed? I use a TP-Link dual band N router and I remember seeing s drain of about 4 percent overnight for 8 hours of full idle with full sync.

I have tried with both 2.4ghz n and 5.2ghz ac, same problem persists
Awake is 3x screen on, I don't think that's normal, somethings keeping the phone awake much longer

so ive done a bunch of other tests, and i can confirm its wifi thats causing this massive drain, not wakelocks, not roms, or anything else.
when the phone is left with wifi on, but not being connected to any network, battery drain is minimal overnight.
its the same on both 2.4ghz and 5ghz bands, so it this a router problem? if so, do you know any tips that could fix it?

Do you have "Best wifi performance" checked? That seems to eat battery.

i have no option for best wifi performance, just "wifi optimization". i found the problem, it has something to do with my new router and its bad compatibility with android devices. the phone seems to be awake 2x the screen on time and the main culprit is "wlan_rx_wake" wakelock

Battery drain on HTC caused by Google Play Services

Hey everyone. I have a little problem. A few months back, I converted my stock HTC One to stock GPE and I have been having constant battery drain from Google Play Services. I was under the impression that the battery drain was fixed with the latest update, but I updated and my battery life is STILL horrible. I have wiped my phone and the problem still persists. Should I go back to stock? I really don't want to, but I've already backed up all my data, so it isn't a big issue.
If you need more information, please PM me ASAP. I really want this problem fixed.

Me too. Same story, same result. I've been trying various things for a few days now. Haven't figured it out either.

For me I'm on HTC Sense 4.4.2 and google play services only makes up 3% of my battery drain. But I have noticed battery drain.

Anyone? Should I just reflash the GPE RUU or go back to Stock? It's been a while since I've done either.

This has been a problem for a lot of KitKat devices. What I do is get App Opps and disable all "Keep Awake" and "Location" permissions for Google Play Services and all other apps that I know don't need those permissions. After that I get much more reasonable battery life. Give it a try.

I've been struggling with this for a couple weeks, trying something different after each charge. The results are always the same (horrible). I've turned off a lot of stuff trying to troubleshoot this. No one thing has emerged as a likely culprit.
Today I concluded the battery drain is worst when away from WiFi. If I am at home all day I can get over 3 hours of screen on time. If the phone spends the day away from my WiFi access point, I cannot get more than 2 hrs.
Just to be clear, this means while I am out and about, I burn through a full charge in 8-10 hours, of which the screen may be on for as little as 1 to 1.5 hours. This is not normal.
Anyway, this sounds like a radio issue somehow. Guess I'll experiment with that next.

Oh I completely forgot something important. Turn off the "Scanning always available" option under Advanced WiFi settings. That's a major battery hog.

Yep, tried that. Even checked repeatedly to make sure it did not turn back on spontaneously (which I and others have observed). Tried different launchers, clearing caches, using battery saving location mode, disabling location reporting, disabling wifi, disabling GPS, tons of different things.
Haven't gone as far as disabling Google Now since I actually use it.
Mostly now I'm looking at why I have good battery life at home and horrible battery life away from wifi.
There a lot of food for thought (some parts more nutritious than others) at http://www.reddit.com/r/Android/comments/1u8alp/guide_to_fixing_google_play_services_battery_drain/

TMO NEXUS 6 Battery life since newest update

My device is unrooted
Everything was going great until the newest update that came last week. Since this my battery life has gone down hill fast. I feel like I'm back on my G1.
I have two questions is anyone else having this issue at all?
My other question is all my previous phones have had SD card spots so when I reset myphone all my pictures are stored there. If I reset myphone do I lose all my pictures?

Battery life has been good for me on that build and the recent fi build as well. Do you have a secondary battery meter like better battery stats? There is no sd card in the phone so yes that would be lost.

of course you can check why your battery times have dropped.. like maybe a stuck process or a certain app draining battery. im nearly 100% sure its not because of the update, but it can be user related. your signal quality could be worse as well, which will also drain battery faster.

why not use an auto photo backup app like picasa or similar?
you really should be doing this regardless. countless times people have come on here all frantic because something happened to their device and they lost all pics needlessly.

When I feel my phone getting hot or I notice the drain is going on I turn off my phone let it set to cool down or I just straight up restart it.
I live a pretty routine based life, Work, Church, Gym, Home.... So my signal life hasn't changed. My usage hasn't gone up or down....but my battery has since that update.
I do have battery apps to keep an eye on things. Display is number (of course) and number 2 which isn't normal is Android OS.

well, what ive found out iver the years that im with android is that battery apps are pointless, and end up using your battery. just check you regular battery usage/stats. nobody uses their phones the exact same way every single time, its impossible. and when you are out, walking around, or driving, your signal quality will change, constantly. and apps, many times they will get a process stuck, and drain much more battery than normal. and then there is google play services, that will occasionally drain lits of battery, especially when its updating itself. in reality, there are numerous other reasons, besides the update, that will make you battery drain quicker. too numerous to list, lol.

my battery also has been going deep underground after last security update! nothing changed in the usage or the number of apps that i keep installed, so the suspect that the drain depends on the update in my opinion is becoming more and more real.
i also keep checking battery's stats and there isn't any anomaly or discrepancy compared to pre-update's stats.

I am in the same boat. I was using about 2-3 percent an hour before the security patch. But since the patch dropped I've been averaging about 10 percent an hour. I have to recharge at least once in the middle of the day. None of my apps changed.

Same here, noticeable difference in battery performance since last weeks update. Only change to apps is I am now using Google fit since last week, thought it was that but battery stats say otherwise.

So last night I backed up all my pictures on my computer and the cloud. Tonight I will reset my phone before bed Ill have a better idea of what it will do tomorrow. It kinda stinks because I have this zooper/launchy/popup widget masterpiece going on my homescreen
Ill report back....

I have noticed the same issue since the OTA patch. Reminded me of my old Galaxy S where it would not go into deep sleep after being unplugged at a full charge without a reboot. I've gone without a reboot and with rebooting since the update and my phone is much better off after a reboot. About 7% per hour lost without compared to about 3-4% per hour lost with a reboot. Pretty consistent usage on a daily basis. Just my personal observation. I'm on AT&T though.

I got better battery life after the update... But then it went back to normal. I was being about 30 to 45 minutes extra SOT but now I'm back to my average times of 4-4:15 hours

Take this for what it is.... I wake up at 545 grab my phone since the update by the time I get to work 7am it would be 96 or below.... I reset my phone last night and the phone seems back to normal at 99%-98%when I sit at my desk..... All apps reloaded and working before bed.....

My N6 is worse off for battery too after OTA update of last week. Seems like Google Services has just gotten a lot more aggressive doing what it is supposed to be doing. I hope Marshmallow will fix this.

Well, mine also loses a lot per hr...and it alsways is the cell interface that is being kept awake over hours of time during a day.
Mainly email and Google services are the apps sucking it off...
Any ideas?

Factory reset and back to normal so far.

5.1.1 Battery Drain

Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?

Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.

I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.

There is something wrong with your phone or app. I have about 100 apps. No problem here.
This is the international version of the phone

Or it's something to do with the AT&T version of the firmware as yours is an international version and not having issues.

Battery drain issue is related to the AT&T 5.1.1 firmware.

Complaint to att to stop messing with a perfectly fine phone. I haven't turned anything off and that's my idle time.

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).

How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.

Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.

Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.

Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.

I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.

Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.

So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.

I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.

I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.
