Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

Juice Defender. The free version of the app, using the default profile, should take care of this.

See how your top 3 partial wakelocks are related to alarms? Particularly the AlarmReciever. Something is regularly telling your phone to wake up at a specific time. You'll need to check/post a screenshot of the Alarms list. It could be any number of things such as apps syncing or Google Now gathering information in the background. Get that other screenshot up and I'll try to help more.
Did the S-Off; Custom Recovery; Permanent Root last night. Everything went fine, rebooted after everything was done and charged my phone to 100%.
Wake up this morning after not touching the phone for 8 hours and the phone lost 30% over night. Looking at the battery stats the Kernel (Android OS) took up 60% of the battery. Wakelock Detector is showing Google Search as a wakeup trigger 92 times.
Before this whole process I was averaging 5-6 hours of screen on time, anybody else seeing some weirdness going on with their battery life?

Nothing abnormal here... Getting the same performance as I did pre s-off
M8, nuff said.
Root and S-Off alone? No. Mods/tweaks that require root? Yes.
Can Google search be a random wakelock sometimes for seemingly no reason? Absolutely.

Install gsam and get a better idea of whats going on. I also flashed the insecure kernel thats floating around and since actually noticing back to normal use.
Questions should go in Q/A btw

No I will look around for that though and see what it's about.
I've been rooting my phones since the Thunderbolt and I'm my opinion/experience nothing is better than stock. Once I started messing with Kernels, custom recoveries, Roms, "tweaks" ect...battery seems to be affected big time. Maybe its things I do as I'm not an expert at any of this and by no means am I trying to bash on devs for the work they do but that has just been my personal experience.

FWIW I didn't experience any sort of battery drain with the temp root before we got S-Off.
root and s-off will not affect battery. Xposed modules, root apps, and other mods can. I have about 6 or so xposed modules running and I still get way, way over 1.5 days of battery life. I had 2 hours of screen on time and my phone used 55% in 1.5 days so.... its pretty good. Check to make sure google now isnt causing wakelocks, turn off location reporting and if you can, turn off google now completely. I really only used it for weather because I don't see much other functionality with it.

I haven't added any apps since running the temp root when I was getting great battery life.
I did the s-off, recovery, and root...uninstalled Verizon bloat and that's it.
Lost 30% over night last night. I drained the battery to 1% last night, turned phone off and charged to 100%, unplugged and didn't touch it....woke up to 70% battery life.

Have you tried flashing the insecure kernel yet? If not, you should and then see how your battery life is.

Clearly you have wakelock issues. Get gsam battery and wakelock detector, post your stats after your phone is idle for a few hours.

I've had both of those running since the temp. root. which screens will give you the best idea of what is going on?
I did flash the insecure kernel earlier this afternoon, and turned off google now.
If anything try a factory reset. It should definitely help.

Post the gsam home screen and the apps section. Also post the home screen of wakelock detector for kernel wakelocks
Most s-off will turn on debug process.
return s on state after you have done modes or you need many tweaks in further.

Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.
Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.
Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.
There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...
The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.
Same problem here.... Huge Android System battery drains.
I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?
Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.
Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.
Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?
To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.
I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.
I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop
Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction
As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.
I recently bought a Lefe Blade X8 (can't find any details online about this model, it was very cheap and had decent gear so I bought it) and I'm satisfied with it except one thing. Battery is draining so fast even when I'm not using it. So I checked the battery stats in the options and saw that phone never goes into deep sleep, it's always awake. Then I started the phone in safe mode to see if it was an app causing it, I left the phone running in safe mode at night and checked the stats again.
Here is the stats: (It seems I can't post the image link as a new user) %100 to %50 in 12 hours without using the phone, WiFi %22, Phone Idle %20.
It seems that I have a Wi-Fi problem, as you can see at top Wi-Fi was off all night but at the stats screen it seems like it was on.
I installed Wakelock Detector and checked the kernel wakelocks, and the biggest wakelocks were ttyC0 and EINT. I will share a detailed Wakelock Detector screenshot when I got the chance.
