I have reached a point of frustration that I can hardly bear anymore.
If I remember correctly, it all started last year around Halloween when I first tried out NewMaclaw's CM11 port. I was dissatisfied with the unusually high battery drain and soon returned to stock where everything went back to normal for the following months. Due to my banking app requiring at least Android 4.3, I started experimenting with the available ROMs again in April. Since then my battery life has never returned to an acceptable state again. It doesn't matter what ROM I use, I would never make it through the day.
I always blamed it on the custom ROMs because after returning to stock for the first time, the battery life was decent again. Due to the suspicious behavior of my battery lately, like dropping or gaining several percent at once upon connecting or disconnecting the charger, I went back to stock for the second time the other day, to determine once and for all whether there was something faulty about the battery. And I thought I would have confirmed just that when the battery drained just as fast on stock. So naturally I ordered a brand new battery (manufacturing date May 2015), and hoped for satisfaction at last.
But this phone is just merciless and continues to punish me for reasons that completely elude me. The first day on stock after a full charge, the battery lasted for a mere 23 hours on stand by in AIRPLANE MODE!!! WiFi was enabled, but only for being able to receive text messages on surespot. No other push services were installed. After the second full charge, I flashed the latest CM11 and instantly noticed that the crazy draining hadn't changed. As a final act of despair, I did an advanced wipe to delete everything on the phone except the external SD card. Of course the effort was meaningless, I was down to 16% after only 11 hours with a screen on time of 2 1/2 hours. All I did was browsing with Firefox. No video or audio, just common websites. Today I did the same thing after yet another recharge, and lost 20% battery after 45 minutes. I always set the display brightness to minimum by the way.
So if it's not a faulty battery, then what the heck is it that prevents the battery from operating normally?!? I really tried everything in the process - flashing several different ROMs, going back to Stock, disabling the location and wake up features of Google Play Services, buying a new battery. What else can cause such ridiculous battery drain, and why did it not occur before I started flashing?
Hello, have you tried to debug which apps and kernel wakelocks eats most battery? Try to install betterbatterystats: http://forum.xda-developers.com/showthread.php?t=1179809. That might give you some hint what eats your battery.
Thanks for replying. I don't think it is any particular app since the drain occurs even while on TWRP and right after flashing before having installed any apps. It is also the same whether I browse the web with Firefox mobile or send and receive messages with surespot which are the apps that I primarily use most of the time. I'll give your battery stats a try anyway.

Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?

I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.
Okay, so.. I have a Samsung Galaxy Exhibit II 4G.
I have it rooted with the root stock from this thread.
With that said, I've had this phone rooted for several months now. Since January or so. Over the course of that time, the phone has run without fault for months. Recently, I've had issues with my battery draining (as well as charging) far more quickly than it used to. I assumed this was an issue with the battery, because there was a slight bulge in it, so I bought a replacement battery that came yesterday. I charged it full (until the phone said it was 100%), from about 5% charge. It took the normal time (as the phone did when it was new) to charge, of just over 2 hours. It died almost completely about 2 1/2 hours later. Currently, I have my phone charging and it's at right around 90%, after just over an hour of charge from 20%. It used to take far longer to both charge, as well as die. What the Hell is going on?
Just a few notes:
This is not the result of heavy usage (for power drain). I say this because even as the phone was idle while I slept, it died on its own accord sometime throughout the night.
My bluetooth, WiFi, and GPS are almost always off, unless I'm using one of them for some purpose, and I haven't used any of those things since the new battery was installed.
There are no applications running in the background, aside from Facebook. I know this because I'm using Advanced Task Killer to kill everything, and it keeps showing Facebook as if it's opening itself for some reason. This is another issue I'm concerned with, so if anyone knows why or how to remedy this, I'd be appreciative of knowing. Otherwise I'm likely to just delete this unnecessary application.
This is not an issue where the phone is reading an incorrect charge over an extended period. It literally is dying and charging faster than normally.
When the phone is rebooted, whether it be through "Restart" (app from Google Play), via the phone Power key, or removal of the battery, the phone drops around 20% battery life when the restart is complete. The absolute reverse happens (it gains 20%) when restarting with the phone plugged into an AC charger.
Is it possible that this has something to do with the root being outdated, or maybe something updated and I'm unaware? I sincerely have no idea what's going on, as this is the first phone I've ever rooted before. I'm sorry for the long post, but I wanted to give as much information as possible.
It sounds like the battery you bought may be defective. Send it back and get a different one.
Yea sounds like you bought a defective battery. Where did you buy it from? Talk to them and see if they'll send a replacement or get another one from elsewhere

Hey everyone!
I got my Note5 near launch day. I love everything about it, except the battery life.
Basically, I am not satisfied. I barely make it through the day with moderate usage. The crux of my problem is idle/standby battery drain.
This has been a problem for me ever since I got my Note5 and even for some of my old phones (M8 on Lollipop).
The Issue: I'm fine with how the battery drains when I'm actively using it. I'm not going to go into much detail about that, but I'm satisfied with how fast I seem to be killing the battery while using it. The part I'm not satisfied with is how much the battery drains when I'm not using the phone. Obviously, this must be an issue with wakelocks. When you look at the screenshot below for Android OS, it is always wake for more than 2.5+ hours in a 15 hour usage period. Now, I'm not sure if that's normal anymore. I don't remember how it was on KK, nor do I know if that's what everyone else is getting.
The Issues Cont: So yeah I have massive idle drain. (I estimated that I get about 1.5-1.6% battery drain per hour. I charged my phone up to 100% and let it sit idle overnight for a span of about 8 hours or so. It went from 100 to 91 during that time). What this means for me is that, I can use my phone less and less because while it sits in my phone, it dies quickly! On GSam, it shows that my battery discharged 38% while the screen was off! Again, I don't know if this is 'normal'. What is everyone else getting?
What I tried: I tried factory resetting. Nope. I tried reflashing the firmware, factory resetting. Nope. I booted into safe mode and left it idle overnight. Still dropped to about 92% or so, IIRC. I actually had the GS6 Edge before the Note5, but I returned it because of the ****ty battery life. Then I inserted my S-pen backward and broke the sensor in the Note5, so I got a replacement. For each instance, I always got crappy battery life. So I am doubting that this is a hardware issue. I tried minimizing the apps installed so minimize wakelocks, but it didn't seem to help.
What I want: Honestly, I just want to be able to use my phone and have it not drain so much while it's in my pocket or on the desk. I want to be able to go into a lecture for a few hours and come out with maybe 1% drain, not 3% or 4%. And I want to do this without rooting. I don't want to trip Knox, and I'm tired of rooting and spending hours tinkering with my phone to get decent battery life.
Attachments: I uploaded screenshots of almost everything I thought would be pertinent. Please have a look and hopefully we can compare results and figure out whether this is normal for a Note5 or not!

I reckom its something you are downloading is doing it. Add one app at a time and see what it does.

Yes there is something keeping your device awake. Rogue app. First guess would be that Facebook messenger app. Look in settings for your running applications, try to limit those to ones you absolutely need using package disabler. If you don't know what's OK to disable, read through the debloating guidelines thread.

Never let Facebook or Games run in the background and MOST IMPORTANTLY disable location services completely. Keep it on a toggle and turn it off until you need it. Always keep it off or Google will ping your location once every minute. It literally halves battery life.

I don't have the Official Facebook app installed.. And I almost always keep location services off, but the battery still drains as it does..
Use the smart manager app to stop certain apps from running in background and restrict background data for apps that don't need it in the mobile data settings.

My battery is amazing and I can say this as I am a battery guru and have spent countless hours trying to squeeze all the juice out of my devices, which includes eliminating wake locks. If you had root you could figure it out, without root you'll have to start un installing apps 1 at a time until it get's better. Also check your exchange accounts.
I assure you something is wrong as my battery life is the best of any phone I've had.

This probably won't be helpful at all as it is a complete shot in the dark, but perhaps you have an app that is trying to get your location continually since you have it off? Maybe try leaving location on. I never turn it off and I've been getting very good battery life on my T-mobile Note 5.

I also tried leaving location on as well. I can't really see an improvement as well. I actually only recently kept location off.

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?

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.

My phone got the update to Android 9 a little over a week ago, and since then it has been losing battery like crazy. For example, last night I left it unplugged as a test, and it lost 30-40% of battery within 6 hours (while I was sleeping). Before the update, a fully charged battery was able to last for two days, now it doesn't even manage one. The phone is often noticeably warm.
I restricted all "consuming apps" some days ago, that did not make any difference. I also tried 3rd-party apps to analyze the battery consumption, but did not find any way to figure out what consumes all the battery in the background / while the screen is off.
Using Google I found other people with the same problem, but I did not find a solution. What can I do?
I had a same kind of problem but it started a few days after a manual update flash. I had been experimenting with some root stuff (mostly magisk though so they should go away by uninstalling the modules) but could also not figure out the reason for the drain.
I also tried to reflash only system and vendor partitions, but ended with a bootloop, so I had to flash the whole firmware again. No problems after that.
I would try a factory reset if I were you.
You can also try GSam battery monitor (if you already haven't) to figure out what's happening with your phone while the screen is off and it should be sleeping.
I upgrade the XPZ yesterday to 4.41 Pie. Charge the mobile after upgrade to 100%.
The current situation looks like:
18hour active, 30 Min Display, a few calls... Whatsall, newsletter, Mail..... are running in the Background, LTE, EDGE and WiFi are always on, BT has a connection to my watch...
88% are still in the Accu. (Save mobil datatransfer is aktiv; additional the option is enabled to reduce power consumption for apps in background)
