Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?
might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

So I don't think I can blame it on that.
Do you have any exchange sync on your phone?

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

System panel paid version with monitoring enabled is the best for tracking apps using CPU.
OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??
Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.
1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.
I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.
You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.
im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?
It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.
GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.
It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....
Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything
Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I stumbled across this post and tried that fix. I'll check back in later to see what it does.
I was wondering if anybody else had this issue or had any suggestions.
Battery life is normally great on the tablet, except every once and a while it gets stuck awake overnight. There doesn't seem to be a 3rd party app that is holding it awake, as Android system and OS is what's using most of the battery.
As you can see in the screenshot, Doze works fine and barely any better is drained, I used it briefly, came home from work and half the battery had been drained.
Thanks for the help
Not sure if it's normal but mine does the same.

I've seen a 30ish % drain sitting overnight a couple of times over the past 2 weeks. Can't seem to find a rhyme or reason for it.
I can't imagine it being "normal" since, with Wifi set to off while sleeping that the device should drain that much.
It's odd and happens randomly, I'm on the same page as you bluestang.
It happened to me once, at night it wastes a 15% battery.
I changed in wifi advance options to not maintain WiFi always awake, only in charge.

That's the setup I have though - so I get no notifications or anything when it's not on. Yet something is still keeping the device up.
I have *exactly* the same problem with an all new device, and with nothing but a game installed on it. After a reboot, if I let the Pixel C right there for a night, then it only drains ~3/4%.
Then I play the only game I have for 5 minutes, and let the device again for a night => it now wastes a 20% battery!
No idea what's going on... "Android OS" appears first in the list of app, but this does not help me so much to find what is actually happening...
The issue still appears even after a full reset of the system (I'v tried, without success).

Exactly. If I reboot the device and let it sit, doze works fine, the second I open an app, use it and put the tablet down, something hangs and keeps it awake. Always Android OS that is keeping it awake as well...
I have this issue too. Are you guys on xceed Kernel?
Whats really interesting even better battery stats Shows no culprit.
I'm on the stock-just-reset-again last version of the system.

I'm on stock - not even rooted
I'm on stock MM here as well.
Also, not sure if it a coincidence or not, but I changed this and haven't seen overnight battery drops anymore. In Settings>Location I changed the Mode from High accuracy to Battery saving. Since the Pixel C doesn't have GPS device, then why use it.
Like I said, not sure if it a coincidence, but battery life has been great overnight since.

So last night, I rebooted before I went to sleep, but overnight the battery drained from 85% down to 57% in about 8 hours.
I decided to check my location settings as per your post and found it was set to high accuracy, so I changed it to "Battery Saving".
I did nothing else(no reboot) until I checked my battery now about 3 hours later, it has only dropped by a further 2%.
Looking at "Battery Monitor Widget Pro" history statistics, it is clear to see that overnight the battery was draining considerably more.
It takes readings every 10 minutes and was showing between 450 and 275 mA being used every 10 minutes overnight.
Since I changed the location settings, most of the time it is 15mA with occasional jumps up to a max of 297mA.
Although this could not be classed as conclusive proof, it does seem to have had an effect, I will keep monitoring it to see how it goes.
Yep, I change that setting on the 19th or 20th and haven't seen any major drains overnight.
I think I may have found a winner with that little tweak
So far so good for me too. I don't know if it is related to the GPS settings, but no more inconsistent major drains so far.
if location services is on it can drain a good deal
Just to add that I had exactly the same issue on stock 7.1.2, tablet was staying awake and draining. Reduced location precision and now only a 2% drain during an 8 hour sleep which is a massive improvement.
Hey everyone,
So i have a stock HTC 10, no custom rom or whatsoever and the battery drain suddenly got very bad. Android OS is on 49% and Android system on 28%. Battery drained 8% over the last hour with 3 mins SOT. I've set back the phone to factory settings and didnt install anything back on it, turned stuff like the GPS location to power saving mode but nothing seems to help. Tons of forum posts also didn't help. I don't want to put a custom ROM on it for now, so i can always send it back to HTC.
One thing that i keep noticing is my CPU usage. Im checking this with the stock android CPU checker and the load is 12.13/13.28/13.68 with only the systemui active. I have forced all apps to stop once but there was no solution. This problem is occuring since mid august. Hopefully somebody is known with this problem.
Edit: running wakelock detector atm

I experienced something similar, funnily enough it was the charger cable causing it. Not sure how or why but as soon as I swapped from the faulty HTC official cable to another cheaper cable the drain stopped. Worth a try

I tried another cable, didnt solve the problem unfortunately.
I'm having a very similar issue. Battery drains way quicker in the last few months (20% in 30 minutes) just from web browsing. A factory reset didn't help me either.
I'm trying safe mode now to see what happens (hold the power button, then tap and hold the "power off" option).
