How can I track down my battery drain?

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.

We have got the same problem with Galaxy Note 3, stock rom, rooted. At some point in the night, this *overflow* starts to keep the phone awake and uses 40% of battery in less than 3 hours.
There is no widget on any homescreen.

Better Battery Stats or Wakelock Detector will help you to figure out what app(s) are causing it.

Unfortunately Wakelock Detector doesn't show anything uncommon. I deinstalled Spotify and Quizduell Premium, rebooted the phone again - and the problem seems to be gone.
This really is strange behaviour and Android should by now be able to find out those problems by itself. This reminds me of Windows, which after over a decade still struggles with problems and you have to install tools to solve them - or reinstall the whole system.

Hi, I know this is an older thread but I've been having the same problem recently and I tried to Google a solution to the problem and found this thread. I too have had high battery drain from Google Services. The phone is basically awake at all times. GSAM Battery Monitor lists *overflow* as the main culprit.
I have location services turned off and I turned off syncing of all accounts except for Gmail. I uninstalled all updates to Google Services and any apps associated with it. I have rebooted the phone multiple times. I'm pretty sure I've tried every battery saving tip I can possibly find and nothing seems to solve the problem. Every now and then I'll get a day of amazing battery life and think my problems are behind me; then it will go back to the same terrible battery life without me changing any settings or changing the way I use the phone.

Major battery drain from kernel wakelock

Hi,
I'm getting a major battery drain from a kernel Wakelock, and I cannot figure out how to fix it. I've tried reinstalling the ROM, to no avail. Using Eclipse.
Screenshot from BBS attached.
Sent from my Galaxy Nexus using XDA

I have the exact same 7 causing all kinds wakelocks over the last week. I've tried everything to try and figure out what the hell is causing it to no avail. If you figure it out, please let me know! I'm begining to think it was an update to an app that started causing this to happen (even though no apps are shown)

try disabling autosync and see if it works,non gsm version?

Nothing set to sync

Power manager service is a combination of all wakelocks in userland, meaning it combines all wakelocks caused by you (music, phone calls...etc), the others (minus alarm rtc which I'm not sure of) are all related to having the phone USB mounted which I'm assuming you have.

I don't know what USB mount means, but why would there be a wakelock for usb when the phone is not connected to a usb cord?
Also, I've tried turning off sync, and the phone still has severe drain. It randomly fluctuates between losing less than 1%/hr to 6%/hr+, even when the phone is idle and sitting in the same place. I've noticed that there are quite a few times when the phone is awake, even though my screen is off and I'm not using it.
If this is an app causing the problem, how do I diagnose the issue? Shouldn't it be showing up in "battery" under settings or as a specific wakelock in Better Battery Stats. I used to easily get 2 hrs of screen time on CDMA LTE, but now I'm lucky if I can get 80 minutes.
I thought it might be the battery itself, so I went out and bought a new one. That was a waste - same issue.
Any insights?

Still can't figure this out. Anyone?

I think I finally fixed my issue. I don't know exactly what it was but it had something to due with the following: Open Latitude and sign out (apparently I was logged back in after the last maps update), kill facebook everytime I close it (keeps way too many services open even though I don't have it to sync), enabled and disabled sync, bt, gps, 4g, uninstalled voodoo mods, re-disabled maps from autostarting, made sure I was logged out of talk, and also logged out of google +, some combination of the above fixed it for me.
I'm willing to bet it was a combination of maps, talk, latitude, and facebook since I tried most of the other things prior to the above. I updated maps and facebook the same day so it could be either of those.

None of those are the issue for me. I completely switched out my ROM and went down to a barebones number of apps. Still having a major issue with the exact same kernel wakelocks. I literally did not touch my phone overnight, and it still lost quite a bit of battery.
How come nobody seems to know what the wakelocks mean from my screenshot posting? This is impossible to diagnose.
Sent from my Galaxy Nexus using XDA

having the same issue. My battery life would be nearly ideal without this wakelock and the "modem_usb_gpio_wake" problem using up the battery. Using AOKP build 35 with lean kernel

Is this not the correct forum to post in? This question has been asked numerous times with the Galaxy Nexus, but nobody had given a solution.
My phone drain is terrible with these kernel wakelocks, but nothing fixes it. I've tried numerous other kernels with the same result. I've killed all my apps. I'm stumped.
What could possibly be causing this out of the blue?

[HELP] Multipdp Wakelock !

I am getting very haigh wakelock (Multipdp , l2_hsic) which is draining my battery , I changed kernals and ROMs , desabled and enabled fast dormancy , Reset factory settings , Full wiped but nothing could help to solve this problem.. is there any solution I can see my betterbatterystatus showing 3 HRS awake while I used the phone (SCREEN ON) only for 1.30HRS
can anyone help?

These wakelocks has to do with 3g and data connection, and will probably be high if you have poor reception or have a lot of data activity when screen off. Not necessarily indicating that something is wrong. Post bbs screenshot of wakelocks from a full cycle please.

Here's my bbs log. Even I'm suffering from this multipdp wakelock.
Bdw I've galaxy note and i reached this thread via a google search. But I guess this wake lock is independent of device.

There are a lot of threads addressing this issue. But all of them end up with a question and no answer after a few messages. I'm also suffering from this wakelocks since many years and it seems most people have given up on this - like me. Just every now and then when this wakelocks appear to have held the phone awake for about 20% of all the time they pop up to my mind again. Realizing that there still is no solution and no one seems to care about ..

Battery drain, wifi not turning off?

I've noticed lately my battery life has plummeted. When I get to work, I turn off wifi, and even after very light use throughout the day, 9-10 hours later it will be giving me the low battery warning. I checked the Battery screen, and noticed the Wifi bar is solid blue the whole day as seen in the attached picture. If I am reading this screen correctly, wouldn't that be an indication that wifi is actually on all day? As you can also see in the screenshot, the wifi logo is not on at the top, showing I do in fact have it turned off. Do I have a problem? Does anyone else know about this issue and have a fix for it, if it is in fact a "issue"?

Go in to your WiFi settings, hit your menu button and hit advanced. Uncheck "always allow scanning"
Sent from my SM-N900T using Tapatalk

Thanks, doing that this morning and will check the battery screen in a couple hours.

OK, that seems to have taken care of the wifi appearing to be on in the battery stats. I will wait until later today to determine if that was the cause of my battery draining quicker. I know there were a few new apps I installed around the same time, and I may have to start digging through those too.

Are u in an area that has low lte strength. If its switching between LTE and hspa+ that is tough on battery. Or location settings, or random apps running in the background. Grab BBS and see what is eating up the battery, wake locks apps etc. Their is am Xposed module that dispatches of wake locks if that is your issue. But I'm guessing its one of your apps or signal.

Go in to your mobile network settings and change the network mode to wcdma/GSM instead of lte/wcdma/GSM if you're always switching between lte and 4g. Try that at least.

if possible grab WiFi at work, and use only that and I bet your battery significantly improves. then when u leave, hop back on normal data and see if that helps

Well, I've tried the setting the mode to not include lte, still getting pretty quick battery drain. There is no usable wifi here due to the level of security my facility enforces. Anything I can have BBS export to have you fine folks take a gander at and see if you find anything relevant?
