CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!

All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.
People are mislead about what works and what is not. I just want to help.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Could you pinpoint some apps? I will update the OP to keep track of possible culprits so that others will avoid triggering this problem. Thanks!
I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!
I'll give it a go! thnx
Active Widgets: WeatherBug Elite, 3G Watchdog, BatStat and Calendar.
Apps: All from above plus Twitter, Titanium Backup, Facebook, Twitter, Tapatalk, Camera360 Ultimate, Root Explorer, Foursquare.
Mostly I use the Twitter client and the browser. Location services are disabled.
It is hard to figure out from the above apps or which is the most probable suspect. Just incase the problem recurs on your phone, dial this: *#*#4636#*#*, Go to Usage statistics and Battery Information and please report back (include also information on the Battery Use in Settings).
I hope we can help others avoid having this problem until there is a fixed solution.
Thanks!
Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.

You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)

Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger
Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!
Bear with me. If you are an expert on android maybe you can help me out here. First off, I have researched the crap out of this problem and still been unable to fix it, so YES, I did search before making this thread.
I am on a stock, rooted Verizon Galaxy S4. I have been watching my battery consumption carefully via the integrated battery settings menu, battery stats plus and wakelock detector apps. Mainly, there is a program or set of programs that typically is called "Google Services" that according to the integrated battery menu is consuming anywhere between 20-45% of my battery, sometimes more than the screen on time! My battery life is around 48hrs with 10hrs screen time but that is on the massive zerolemon 7500mah battery which I just bought, so I am not sure if that is above, below or just average (i.e. I have no real standard by which to judge).
Like I said I have read probably every thread about this problem with remedies such as; disable location, turn off google now, turn off google maps reporting, uninstall updates for google play/google play services/google framework settings, turn off google sync etc. I have tried them ALL, none seem to work. I have a feeling the issue is perhaps more in depth and above my head.
It gets more complicated. Although the stock android integrated battery menu reports it as using a massive amount of battery, the other two apps I mentioned above do not even report it, or at least not under a name that I regonize (perhaps that categorize it under a different process?). Under them screen time is by far the highest consumer.
So what to make of this? Is it a false report that the stock integrated android battery menu is reporting, and thus something to disregard? I doubt that because there are many other threads out there of people with the same problem and questions I have. But It's also not like my battery drains within hours. For instance, today I have been off the charge for 12.5hrs, with 3hrs and 40min of screen time and have 63% remaining on the 7500mah zerolemon extended battery.
If you can help, please do. If this is indeed a major drain I would really like to fix it.

Yes that seems to work, but it's not really a "fix" as now I cannot use the location feature of many of my apps. Basically traded one problem for another, albeit lesser one.
I'm still trying to figure it out as since last update (MEA firmware) , my phone is heating a lot.
I had this problem with data connection on, I had this problem in airplane mode, but not strangely with having connection to wifi.
I also observed that google services and android system is consuming most of the battery. earlier when I used to get 8-10% consumption in full use in an hour, now, 8-10 % is consumed within 30 mins.
No tweaks are working. Frozen a bunch of apps but the problem is still there.
Just now I've uninstalled fileexpert HD , as "greenify" told me that since last 20 minutes my phone is on, it has taken 250+ wake locks.
I'm charging my battery to full to check if that solves my problem.
will try to disable location services and report back on the results.
Bump
Have the exact same problem, before the latest firmware my phone had awesome battery life, and now the battery goes from 40% to zero in just a few hours without any app running when I'm sleeping... it's horrible. Same problem with my wife's S4 since the latest update... It absolutely sucks.
Hi All,
I've attached a screenshot of the battery settings, my screen-on-time at this point was 1h48m - it seems to not be able to calibrate at all and drops and rises as it feels. I unplugged my phone this morning when the alarm went off and snoozed myself for a few hours, the phone was off when I woke up, when I turned it on it was at 66%
I've reloaded my ROM (MIUI v5) and it doesn't seem to have made a difference. Is it my battery dying or is it the ROM? I haven't seen anyone else using MIUI have these issues.
Any advice? Should I think about replacing the battery?
Seems really bad and battery problems really gets fustrating at times..
Check if you have any apps you recently installed that might be causing the drain (Games tend to stay in background hogging batteries)
Reflash your rom if possible, with a full wipe to be assured of no rogue apps.
If the problem persists, then it might be due to a worn out battery. Replacing the battery usually solves most problems :good:
You can see my battery stats here: http://imgur.com/a/5y9pY
I don't currently have a SIM on my Nexus 7 32GB 3G, so it's constantly on Airplane mode. However, these times are really weird, especially when I only use it about an hour or two a day nowadays. Is anyone able to point me in the direction that I need to go to find out the root cause of this battery drain?
Running CM10.2.1. Previously this battery statistics were also observed when I was running ParanoidAndroid.
Any help is greatly appreciated. Thanks!
You need to see and post if you want, the times waking device and time held awake screens from Gsam. They are the screens that should show the culprit.
Found it.

Googled about it and found this to be a widespread issue... was not able to find a solution to it though. Any recommendations?
This thread has some talk on that wakelock...

I have this issue and have spent the last 2 days trying to fix it to no avail. I'm wanting to start a fresh to resolve it which means wiping internal storage of music/photos etc. One question though, what's the best way of doing this to them install a fresh ROM?
Is this being reported by GSAM with the root plugin, or another battery monitor?
Also, are you on stock, or another ROM?
I have noticed my top app battery drain by far is the Mediaserver - however my battery life doesn't seem to be suffering unduly.
I'm wondering if it isn't actually to do with the indexing that the System (mediaserver) performs but the "Audio On time". If you view the details of the apps power usage in GSAM it shows quite a high number for "Audio On". About the same as my SoT. I have no idea if this is expected/normal behaviour (ie whenever the phone is awake the process turns the audio on) and is a red herring or if this is in fact an issue with it activating some audio functions even when nothing is playing.

Yes it is and it's making me go mad! I might uninstall it if this is the case. Has anyone else reported the issue if it is one?
