Hey everyone
Got a Nexus a couple weeks ago after having iphones for a couple years. Loving it so far.....ICS is very polished.
Initially, my battery life was adequate. However, recently the OS is using 45% battery and the phone gets a very hot when idle (I can feel the heat in my pocket)
I did a factory reset and still the same problems.
Is anyone else coming across these issues?
An old bug cropping up again?

Can you please install Watchdog (https://market.android.com/details?id=com.zomut.watchdoglite) and let us know if it's the suspend process (which shows up in the battery meter as part of "Android OS") burning through the battery?
My phone has been on standby for about a day and has 80% battery left. However the battery consumption shows:
42% Android OS
37% Phone Idle
16% Cell Standby
- Also what is the difference between phone idle and cell standby
MY BACKGROUND APPS RUNNING ARE:
- Battery Monitor Widget (I need this on so I can tell what my battery life is easily)
- Google Services (What is this, can I kill it?)
Media (What is this app, can I kill it?)
Music (Again what is this, what happens if I kill it/should I? I never used it.)
I have the same problem. My SGN died after 7 hours without any usage.

Yup, me too. This morning, I took my phone off the charger at 98% for an hour and 15 minutes and didn't touch it. The battery had gone down to 88%, with Android OS using 64% and Android System using 14%. The phone was 'awake' for the entire period. I've had my Nexus since Wednesday and I haven't been getting great battery life. I'm hoping there's a fix for this.
Same problem here... (I testing radio UGKK7, XXKK7 and XXKK1... all with the same problem).
- Lightflow increment "Android OS" battery use.
- By using, Wi-Fi "Android OS" uses less battery.
try disable wifi when not on and unchecked "use wifi network" for location.
another thing could be some active widgets, i remember this was a problem a while back.
Note sure that this has got to do with wifi at all as I reset my phone to factory and I still have the 'Android OS' usage taking 23% of battery. I have no apps nor have I yet linked phone to my Google account.
I have read some comments to do with the Galaxy S2 which too suffered from the same problem. I remember reading something about Samsung driver implementation causing this with the S2. I will update the links when I find something conclusive. Also I have another HTC desire that has the AOSP code compiled rom and that does not suffer from this at all and it is happily sitting idle at almost 2 days with nearly 70% battery still left.

Yes, the problem was with the suspend process eating up CPU. You can install Watchdog and set it to watch non-Android processes, and that will be able to tell you which "Android OS" process is actually the one eating up battery.

Is samsung aware of this problem? We need to file complaints.

Do you have your email or anything set up to receive things instantly? That can have a noticeable impact on your battery if so
Thanks Chirality, but I assume that this is happening to all users? Samsung have seen this before so shouldn't this be fixed from the very start? Wrong person to ask this question to, but it is annoying..
Anyways I will install Watchdog like you say, but unless I can kill the 'suspend' process, I am helpless.

No, that's why I reset the phone to factory settings and the current behaviour is without any apps, or registration with google, no emails, nothing installed.

Is there anything in the logcats that could hint to a problem? Like errors or something unusual that it keeps repeating
I have the same problem with high system CPU usage. I used SystemPanel to monitor the phone (unplugged, standby mode) during my 8-hour sleep and here's the results.
The System Processes were using 49min of CPU time while the phone was idle
When I clicked on the system processes I got a list of individual processes. Anyone knows what are there kworker processes for?
When I clicked on one of the System Processes (kworker/u:1), I got its CPU usage. It was doing something almost the whole time
Finally, I should also mention that the phone lost about 7% in these 8-hour test. Seems ok but I think it would be even better when this high system CPU usage is fixed.

Hmm...Now that you asked this, I remember watching logcat output and was getting a null Notification event almost one every minute a couple of days back. I therefore proceeded to uninstall all my widgets/apps but I could not reach to a conclusive outcome.
Anyways as Chirality pointed out this post (Link) indicates a 'suspend' process issue. And this guy identified the process causing it (Link), I think!

A driver issue definitely sounds plausible but there are also a lot of things different between these two phones, especially between GB and ICS.
Watching /proc/kmsg should show something if it is an issue with the kernel

Do i need to be rooted to be able to read this?

Chrality, xHausx
I have installed Watchdog and set the settings to what you indicated. I am a bit confused around the app, so I have added screenshots to update you of the data at my end.
Do let me whether you see the issue immediately or need any further information.
My experience is somewhat the same.
Out of the box battery life seemed pretty good. After the update to fix the volume issue I started to notice that the battery would fall even when the phone was idle. Android OS was the culprit. I am now running MCR and I have the same issue.
It's not terrible battery life, but it's substantially worse than it was out of the box.
I did wonder if the problem was related to how they fixed the volume bug. Is something always running to pick up the volume bug problem and deal with it when it happens?
Just a thought.

Interesting. I've been thinking the same thing, and the annoying thing about that is the problem doesn't affect my network (T-Mobile), so I could be getting reduced battery performance for no reason! Ah well.
Hi everyone. On Tuesday I recived a brand-new One X. I applied all the updates (it was until .11). It seemed that the battery didn't last a lot, and on the stats it showed a high usage coming from Android OS.
Yesterday I applied the Sense 4.1 update from the RUU, as on some forums I've read some suggestions to do a factory reset. – I've all the default settings.
Today, it happened the same. (I attach some screenshots).
The problem isn't the usage of the screen (14% –*18minutes), instead, it shows the biggest drain as "Android OS" which had a keep-awake time of 5h 16m out of a total 6h 11m of usage.
It has drained almost 4% every minute.
I don't think that the problem is caused by any app, as I have the stock ones and WhatsApp, Flipboard, FB, Twitter, Instagram, Pocket, Evernote and Chrome, yet, I haven't really used them...
Could you suggest me anything to try to solve this battery drain problem? I checked the battery stats thread and Android OS usage is 5–6% on average.
Some app is preventing your phone to sleep, there are 2 ways to find out, start uninstalling apps untill you find the app causing the problem or better reset and install one by one
Hi,
I've further researched and I found a question on Stackoverflow – I can't post links yet – which says that by using the following command
Code:
adb shell dumpsys power
you could see what wakelocks are on the phone.
I've tried it, but it seems that there's not any wakelock:
Code:
mPartialCount=0
mWakeLockState=
mLocks.gather=
mBroadcastQueue={-1,-1,-1}
mBroadcastWakeLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mStayOnWhilePluggedInScreenDimLock=UnsynchronizedWakeLock(mFlags=0x6 mCount=0 mHeld=false)
mStayOnWhilePluggedInPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mPreventScreenOnPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mProximityPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mProximityWakeLockCount=0
mLocks.size=0:
mPokeLocks.size=0:
Should the app that created the wakelock be running, or it can also be stopped? Would work disabling an app instead of uninstalling it?
I'm not a Pro in this matter but I had that problem with every ROM I was using ARHD, IC u name it!
I found a temporary solution to that problem. Turn ur phone off for a good 10 minutes. Then u will see it go away completely to 2% or 3%.
Doing this on a 80+ charge does the trick!
I'm using the stock ROM. I will start by using BetterBatteryStats to find any deadlock.
Before using BetterBatteryStats I disabled automatic uploading to Dropbox, and I think that's what caused the big battery drain. Now, it's a very good battery life.
disable auto-sync if possible...
Android OS battery drain on unrooted HTC
I have the HTC one X and unfortunately ive been plagued by issues from day one. initially the issue was with the screen. I raised a ticket and the HTC singapore guys took like 10 days to get it replaced for me. after the 'repair', The WiFi reception wasnt great and there were tool marks all over the body..!.. i raised a ticket again, and this time they changed the stuff pretty quick. I got a new body and they claimed to change the internal boards and stuff.. Well i got my fon back the day before and the WiFi was great. But then came the next issue. The battery drain. and it was the Android OS process which was eating up by battery. I have attached some screen shots.
I read through a couple of posts in Xda and installed BBS. BBS showed a kernal wakelock which was keeping my phone awake 100%..!..
Could anybody help me resolve this issue please?. i have flagged the issue again to HTC, but im just plain tired of the cat and mouse game that i play with the service centre guys..
Also, Could this be a hardware issue or is this just a software issue?.
PS : i have tried factory Reset once and it did not help me.

Could you solve your battery issue?
Same problem here, no solution yet !!
I've noticed recently that my battery seems to be draining quicker than usual, and I haven't been able to figure out why exactly. I know people here know a LOT more about this stuff than I do, so I figured I'd see if someone could help.
I use GSam Battery Monitor, and I took some screenshots of the top drainers to see if it would mean anything to someone who knew better. When the battery started dying quickly, I installed Greenify and added almost every application to it so they wouldn't drain constantly. These screenshots are after Greenify was installed.
I'm running CM 10.1.0-RC4, with no other modifications to my system. Thanks in advance for any help!
seems that kernel is on max speed most of the time
Happened to me on the one v but it usually goes back to normal after a while
Hi there
found today that Android OS is running with 97%.
Never had that behaviour before
Tried to fix it with a reboot but stays the same
G3 is running V10h since update has been available without any problems and I do not have any new apps installed.
Very strange.
Any tips and tricks to solve that?
Funny that this high does not affect the battery duration at all, only 5% over night.
I have "Android OS" on the second place, right after the screen. Nothing to worry about. Even the slightest thing can show up as a "big resource" user if there is not happening anything markable.
Anyone else seeing 99008 showing up in your battery stats draining a decent amount of battery? Any clue what it could be or how to fix it?

I commented on what I think a likely scenario is here: http://forum.xda-developers.com/showpost.php?p=63482256&postcount=5
Maybe it's of some use or you could use adb to find out more after reading it. What you need is any utility/app that allows you to see what image is associated with whatever battery usage throws up on the screen. I think "Quick Info" is one and "GSAM" might be another. They're free. If you find the image, post it.
I think that is caused by uninstalling apps that used a significant percentage of your battery life. Did you recently uninstall anything?
Hmmm interesting I did uninstall an app or two recently one of them where showing up in the battery history I uninstalled it because I don't use it so that may be it
I have been getting the same item in my battery stats. No apps uninstalled. Very odd.
Same here. No idea what it's for. Anyone with any clues?

I used "quick connect" on my Samsung Galaxy S6 and I think this is what caused it for me.
