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.

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.
Hey guys, I was getting terrible battery life when the phone is idle. I looked into it to see what was going on. First off, I am on the stock rooted deodex'd ROM that scrosler posted. The biggest problem was an app I installed called Light Flow Lite, it controls your LED. It had over 6 hours of wakelock today. Removed it, not worth it at all.
The second thing I found that was interesting was after that, the phone STILL wasn't hitting deep sleep. I poked around in BetterBatteryStats and didn't find anything in there that would explain that. I then ran a "top" (in terminal or adb shell, type top -m 5 -t). Everything looked normal, nothing crazy. But I turned the screen off and let it run for a few seconds. I got a massive spike in CPU (anywhere from 15-35%) for system_server with the thread "WindowManagerPo" (which is likely short for WindowManagerPolicy).
I did some searching and it turns out that there is a bug with auto rotation that causes this. Essentially, the sensors don't stop looking for orientation change when the screen is off. I found reports of this in the Nexus S forums, GS3 forums, etc. This leads me to believe it is a Samsung kernel issue, since that's the least common denominator when it comes to the phones that had this issue. If you don't use auto rotation, you probably aren't encountering this issue (but keep reading for some good info below!) But I use auto rotation, how can I fix this?
Download an app called Auto Rotate Auto Lock. This app will turn off auto rotation when your screen turns off and enable it back when you turn the screen back on. This looks like this should really help to combat this bug and it handy for people like me who like auto rotation but don't want to have battery life suffer from something as stupid as this. I have verified that my phone now does enter Deep Sleep easily, and it hadn't hit that all day!
I also recommend an app called CPU Spy Plus (XDA thread). This app shows some very valuable information about your processor. You never want to see "Deep Sleep" under Unused CPU States as this means your phone isn't sleeping and is wasting battery!
It would also be good to download BetterBatteryStats (XDA Thread). This will help you nail down battery drain that you won't see in the stock Battery graph found in Settings. Things or importance are Partial Wakelocks and Alarms.
Monitoring these apps can really help you to increase your battery life on your phone. If anyone else is having bad battery life when idle, please try this out. I'm sure this will help you Feel free to ask questions, I will try to answer them as best as I can!
I have autorotation turned on but not the face orientation sensing. I haven't noticed a significant battery loss, at 19 hours with 10 left according to battery spy, but I'll give this a try and see if it increases it any.
i'll give it a shot. i was wondering how at work it would drain 2-4% an hour but at home with a crappy signal i'd only lose 6% all night.
at work it's in my pocket and at home it's stationary.

I have noticed Google Talk drains batteries when your signed in. By default your phone will sign in. If you don't use TALK, sign-out of the app and you will see increased battery life. Your wont ping the internet as much which saves batteries.
Thanks viperboy I took your suggestion and so far it seems to be helping.
I haven't tried that app yet, however I have definitely noticed an improvement in battery life by disabling auto rotation. Thanks for the info.
THIS NOTE 2 IS SENT FROM A GALAXY WHERE SAMSUNG SPRINTS TO THE TOP, AND JELLY BEANS EAT APPLES!!!!
after a bit of troubleshooting i found that battery monitor widget pro was the cause of my drain. after removing it i went from 2 to 3% an hour to 3% overnight. this really sucks as i love the info bmw colleects. this is the only device i have that suffers drain from the app.
Thanks for the info. I have been losing % 15 battery every night while I'm asleep and was wondering why

Thanks for the suggestions. I have heard so much about the great battery life, but that has not been my experience. I had a Note 1 and I had no problems. With Note 2, the battery drains to about 1/4 after about 7 hours with limited use. I have turned off auto rotation, lowered the screen brightness, changed auto check settings for email, and don't see much difference. In addition, it seems a shame that I should have to figure out ways to use fewer functions to make battery last for phone calls, since I never had to do that before. Any ideas?
Thank you for this info. I consistently get a full days charge of of my phone but was pretty clueless when it came to what was draining my battery. I've used the rotation lock app and will report my results to see if I get even more remaining battery each day.

As viperboy mentioned, BetterBatteryStats is your friend. It really will help you figure out why your phone isn't sleeping like it should. It definitely takes some time to monitor and figure out what the readings mean to help point you to the apps or settings that're affecting your battery, but well worth it. I also like having a better understanding of how things work on my phone.
i did a double check on battery monitor widget pro and it started draining my phone again. as soon as i uninstalled it everything was fine again. this is with both cleanrom and blazer. i'll just wait til official support comes and try it again.

Have you tried the Perseus kernel? I hear the battery life is improved with it. So may be it doesn't have the rotate issue.
I've been using cpu sleeper and I easily get about 30 hours. Looks like the new apk fixed quad core. So when the phone is off it only uses one core and shuts down the other three and lights them back up when you need them.

That app is unnecessary. Pegasusq governor already does that by default. Goes to 1 core and 200mhz when screen off, at least that's how my Note 10.1 was. I assume it is the same here since the International GS3, GN 10.1, and GNII basically share the same kernel with a few minor differences.
I think I may try the perseus kernel today to see if it improves battery.. I haven't heard it does.. I just been seeing people do that benchmark stuff with it

Interesting... I have a script that reports on CPU freq and, when plugged into USB (maybe the wall charger too, didn't check), it appears that the kernel runs cpu0 and cpu3 all the time, even when screen off. With the phone unplugged, it went to using only cpu0 but didn't cap the freq. It was spending a good amount of time at the higher frequencies even though I had nothing running.

I installed the app to turn the rotation off when the screen is off so far everything good but when I get a call this goes crazy because the screen goes while in call. I know this because I have an smartwatch which it has a notification app and every message that the phone has my watch vibrates with that message and I had a call few minutes ago my watch started vibrating non stop until I hang up.

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.
I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

Mine only does that under 15% battery. Seems like its doing nothing over that.
Sent from my LG-H815 using Tapatalk
The default is under 15% and when it kicks in, i definitely notice a difference in the phone.
You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.
Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:
I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.
Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.
So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.
Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.
It saves battery

yup..i feels like the batrey saving mode is draining more batrey life than not using it..is there a solution for this ?
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.
Hi,
My mzp display consumes more battery nowadays.
Anything went wrong? Kindly suggest what needs to be done.
TIA,
Dinesh

Hi ,
What's SOT means? And what other stats are required?
Screen On Time. Show me a screen shot of the history details. You just click on the battery stats and it'll show the history details.

Hope the below screenshot is expected from me.
youre charging your phone lol... You have to show everyone a clear battery cycle. Meaning charge your phone all the way to 100 until a low percentage. Then take a screen shot. Show us the SOT and the history details. I'm guessing you have a lot of wakelocks.

Okay will take a SS n post my usage. I have not enabled any wakelocks to any app. Any way to find that?
I had a recent issue with battery drain as well. Read in 1 of the threads that it could be due to using Magisk and activating Magisk hide. Not sure if you're rooted but if so, and you use Magisk, you might want to see if that is your culprit.
In the ss the second most consuming thing is android system. Used to go to sleep and wake up with the same % but now it consumes 1-2 % at night. And that is only because of Android system that appeared a couple of weeks ago. Except from cleaning cache there is nothing else on the web , only a software reset. Anyone else with high Android system consumption?
