My phone has been off the charger for roughly 3 hours and my batter is already down to 66% .. I spent about 10 minutes in the market and that's about it.
Battery status looks like this-
Android OS 70%
Display 10%
Android System 5%
Cell Standby 4%
Phone Idle 3%
Market 2 %
Any ideas on what is going on with my android OS?
*Running completely stock*
Rooted phones have a few extra options like cpu settings unvolted kernel. Stock phones-try to lower you brightness, shorten screen time out, turn off gps and bluetooth. There is a app called juicedefinder that seems to help.
check what services are running maybe?
settings>applications>running services

You can click on Android OS and get a more detailed break down of what is using up the most juice in that subset... I am betting you downloaded an app at some point that is corrupt and running non-stop draining your battery.

I clicked on it from the battery status but it only lists CPU Total, Data Sent, and Data Received. Doesn't break out what programs are doing it.
Under the running services is there a way to see the programs power usage or perhaps an app that will do this?..
On a side note my battery is now down to 30% with it's only uses since it was at 66% was taking it out of standby every once in a while to see the battery usage. Android OS is now up to 73% of the usage..
You either have a high refresh rate for data on a running service, or you downloaded a program with crappy code that doesn't kill itself when not in use.
List your installed programs.

Odd... I am on a Desire ROM, but when I open up my system battery usage, AndroidOS isn't even showing, it has a long list of apps, and appears to be in order of battery usage. I could swear AndroidOS does the same.
Download Spare Parts from the market, then click on Usage Statistics to see which apps have been running the most, etc.
I am using Task Manager to autokill apps but I feel this tool is itself eating battery no??
How do you like this ??? ...(but: no WiFi/3G used !!)
Check out the battery & hours!

Yes.
Task manager are running service(battery eaters) that monitors and closes apps in saved states(not battery eaters) and other running services. It's counter intuitive to run autokill applications because it itself, is wasting battery killing stuff that doesn't need to be killed.
Task managers that autokill are good for applications that have ****ty code and don't close themselves, or for programs that hang up.
Nothing More
If you're autokill killing services alll day long, why are you even running the services? Just run then as needed.
my display is like 65/70% of the battery use
So you are using Cyanogen ROM
Try Emo or Desire Roms it should fix display battery problems

I've tried more taskkiller programs (ATM, Taskiller, etc) and came to the conclusion, that the ONLY auto task killer which actually SAVES battery (compared to setup w/o task killer program) is Task Panel. Don't ask me why/ how, but with TaskPanel my N1 is fast en lean, battery lasts about 130% of native (w/o/ TaskPanel).
Of course, question is whether task killer necessary, but as I use lots of widgets, programs, in my experience task killing helps to keep my N1 fast..

So after some systematic disabling of apps it seems the culprit was the Touch Input that came with the HTC_IME .. After disabling that I am back up to regular battery life and android OS is only using 2% of my battery again.
Sometimes the Android OS is stuck at 70% and the battery is drained really quickly. A reboot fix it. Next time I have to check what exactly is causing that Android OS is at 70% battery usage.

just to be sure, you're using nexus one? if so, can you elaborate more on what app or service you're talking about. thanks
that's weird because i am using the HTC IME keyboard and i have touch input running too, but my display takes up 90% of my battery all the time. must have been some weird glitch.

Yes this is a Nexus One running stock ROM.
It may have just been a fluke with the version I downloaded from this forum. I am going to install the new version as soon as I get around to it. Not sure how it did it but as soon as I disabled it my battery usage went back to normal.
I was having this same issue on a MyTouch 3G running a 1.6 Rom (TheOfficial), and it appears it's a common problem on the Droid as well from some research. I was using HTC_IME. I just switched back to the default android keyboard and will see if it fixes my battery drain issue.
(My thread in the mytouch devel forum got locked for some reason, even though I consider this a legitimate concern for ROM development, since it's a rather major and hard-to-find defect.)
UPDATE: the "Android OS" task has stopped being a problem after I switch from HTC_IME, but "Cell Standby" is now taking up 50% of the battery, so the battery still drains, but slightly 30% slower.
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!
Click HERE and read the bottom part for more details.
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

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.

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.

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.
Sent from my HTC Desire using XDA App
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.

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!
I received my phone 2 dags back, and i spent most of those days setting it up. Charging it when needed and not quite keeping tabs on the battery life. The phone also used to get hot these few days amd i assumed that it must be the tedious setying up that was making it hot and dischargibg it rapidly.
Today was my first proper day of usage.
I unplugged the phone at 7am and by 12:30, it was 0%.
I'm attaching the stats.
Is this normal? What steps do i take to fix this? because this isn't something i can live with.

That's definitely not normal by any means. I was going to say something until I noticed the screen ON bar at the bottom...seems to me that it's either a rogue app or multiple rogue apps.

Not sure if you're rooted, but there's specific apps to help narrow it down, for that hopefully someone else more knowledgeable can chime in. I do know however that both Facebook and Facebook Messenger are horrible when it comes to maintaining good battery life. So an option would be uninstalling those and logging into Facebook through Chrome or any other Web Browser that you use. And now it gives you the option to notify you through the browser for new notifications.
I'd also reboot the phone once you've done that, charge to 100%, take it off the charger and reboot again and let it drain. Give it a charge cycle or two and so how it goes.
I would recommend GREENIFY app , even for non-rooted devices you can manually or even automatically force close any apps which are not necessary to remain active all the time (e.g WhatsApp and messaging apps should not be included). You'll be surprised how many apps keep running and using cpu and network resources even after you "close" or stop using them.
I join the recommendation about FB and FB messenger - same for Instagram - these are memory hogs. Your situation is absolutely not right - please report - would like to hear how you are doing.
It seems package disablers are pretty popular now for helping you disable some apps that you wouldnt otherwise be able to disable. It seems alot of peoples reasoning for disabling apps is to save battery but iam wondering how much battery is the package disabler app itself using? After all. Its constantly running in the back working to keep those apps from waking right??
First of all, once you disable the app, it is disabled forever, no need for PD. As far as how much saving you get? 3 nights ago charged phone 100% before sleep, wake up 98%, 2 nights ago charged 100% before sleep, wake up 80% left. That would be x10 higher power usage . I went to app manager and force stop about 5 apps and everything went back to normal. Some apps can be brutal on battery (not sure if by design or it crashed) and all those people complaining about poor battery, it's not the phone, it's some programs running in background. For example If I don't even have facebook account, why is facebook running on my phone? If you know what you're doing you could easily double battery life.
Iam not fully understanding your reply! Are you saying package disabler is the reason your battery life improved?

I bought but haven't really touched Package Disabler Pro.
I think its better to have 1 app controlling/blocking multiple things than having multiple apps running multiple things and wasting battery.

I run package disabler pro and it shows as 0% battery usage with 37% battery left. I don't think the app runs in the background, it just force closes the apps that you select and disables them from running, so I think it helps your battery seeing it stops other apps from using your battery.
Is there any apps in particular recommended to disable besides the obvious? When i view the list of files within package disabler. It shows some items using ram but most of them seem to have no affect on battery life and aren't intrusive in anyway so i imagine it's just not necessary to disable them. I mainly wanted to disable Knox and bixby but bixby doesn't seem to be using any battery so again, iam not sure i need to disable it.
To make quick points in simplest way:
1. For best performance, only programs that you actually use should be running on your phone.
2. Package disabler is the program to use for system files, especially now, since we have no root yet.
As far as looking at the battery statistics, they are not very reliable IMO: I had my phone discharging 2% overnight and at other time 20%, when I looked at settings/battery/battery usage they looked almost the same in both cases: Android OS, Android System, Device Idle etc. no smoking gun and yet the phone was using battery x10 more. I do not know what caused this excessive usage, but I went to APP manager and manually force stop every non system application and all went back to normal. This is not the first time this happened to me and IMO simplest solution is not to have unnecessary software running on my phone, less chance for the programs to go haywire.
My husband got a Tab A 10.1 last year for Christmas and uses it mainly for streaming music on YouTube and surfing marketplace on Facebook. While I know both apps are battery hogs, the battery drain is still unreal. Just having the tablet on the "home" screen for 5 mins will drain the battery 14%.
I have either removed or disabled all the apps not needed, have optimization setting set (says battery life is over a day haha), brightness is low and on auto, and also have an auto app kill installed to stop apps in background. Have gone through and removed background permission and set allowed open background to only 2.
Short of rooting, which I prefer to not do with the lack of options, is there anything else that I can do here? Is this a common issue with this tablet?

If you are having that kind of battery drain just on Home screen, without the music or facebook apps running, either the battery is bad or you have some kind of malware. Have you tried factory reseting the tablet? Or running malware detection app?

I have run the built in tablet scan for virus and malware threats but have not installed an independent app. I will try that though and see what happens. I will also look and see if this tablet is still not under warranty, but honestly just going a phone repair to have battery replaced might be cheaper and faster than sending back to Samsung. Thanks for the help.
