My dad's galaxy s2 seems to drain pretty fast. When hardly using the phone (screen time of less than 20 minutes) the phone dies after being idle for a maximum of 13 hours.
When using GSam Battery Monitor to see what is draining the battery, everything seems normal expect for 'Kernel'. 'Kernel' uses 40% up to 85% of battery out of everything running on the phone. When the phone has been on for 10+ hours 'Kernel' is using more than 2 hour cpu time.
When looking at BetterBatteryStats nothing strange shows.
When looking at Cpu Spy the phone deep sleeps a lot (60-80%) and 200 Mhz being the most used frequency after deep sleep (15-35%).
Pretty much everything seems to be fine, no apps draining the phone as far as I can see. No sync stuff draining the phone.
The only thing I noticed is that 'android system' is using the accelerometer and gyroscope for quite some time (it seems the accelerometer is always in use, the gyroscope can be in use for 30min-2 hours depending on how long the phone has been on).
For me it's not clear why 'Kernel' is using that much bettery. Looking at my HTC One X for example it almost never uses more than 9% battery (out of 100% which includes everything, radio, apps, wifi, etc). On my HTC One X 'Kernel' also almost never uses more than 25min cpu time even when the phone has been on for 13+ hours. It sounds to me that the kernel shouldn't drain the battery that much, especially when the phone is deep sleeping a lot.
I'm running CM9 RC2 (been using the CM9 nightlies before RC2, same issues). Tried other roms like NeatLite and NeatFull. Tried stock kernels from those roms, and tried other kernels as well. Same issue.
Any help is very appreciated. Thanks in advance.

ok it isn't normal that the phone die after 13hours while sleeping, however the only app that will tell you every thing about the battery drain issue will be better battery status , try it and provide us with log, you will see about each app, and know if there is any app missbehaving, but if every works as expected , i think it will be abattery issue, change it and try,
btw: with cm9 you can't use stock kernels, use aosp/aokp kerenls, stock kernels only with samsung based roms

I meant stock kernel as in the stock cm9 kernel.
I do think GSam Battery Monitor is a decent app for a global overview of what has been using the battery. When it says the kernel has been using the battery (by using a lot of cpu time), I do believe that's true. Especially since other phones in my household that aren't draining show the kernel is hardly using cpu time.
Here's a log file from BBS. Nothing strange to me, but maybe I'm looking at it wrong. See the attachment for the BBS log.
Bump, same issue. Accelerometer is also on for multiple hours. Battery drains too fast, noghing is amiss in BBS or Gsam.
i have exactly the same problem with my fathers s2.
can someone help?
michael
the same problem is with my SII & its started after I switched to AOKP JB MILESTIONE 1 ROM with Dorimanx Kernel..... Kernel CPU usgae is very high when screen is off for 5-6hrs.
Now, i have switched to Siyah kernel.... lets see if that improves the situation.

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?
Install this app:

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!
I have a stock SGS2 with a lot of widgets running. I use BetterBatteryStats and have removed the high power usage apps.
Past few days, the phone uses a lot of battery at night. Yesterday it had 32% battery and when i woke up it was dead.
Are the rest of you also seeing this much battery consumption every night ?
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
I gave up with the stock S2. Rooted it and flashed MIUI to it along with the Siyah Kernel. Now it uses only 6% for the whole night. Battery usage is so much better now.
People having issues with battery should try the siyah kernel and change governors (unless some app was draining your battery)
yeah, actually some new users will experience battery problem. however, some says that when time goes by, the problem eventually sorted out itself.
i am guessing the phone need "warm up time"
I had the same problem with stock rom. you have to remove the preinstalled useless samsung apps. then battery consumption is better.
i am now on cm7. everything is working and around 8% per night with a lot of background processes (tasker, lbe, scheduled titanium backup).
Don't always turn on wifi or data unless necessary.Turn off background sync.This should help a lot even u r using stock rom.Kill tasks with built-in task manager.Make sure useless apps are not running in background.
With these tips,my s2 with rooted stock rom and stock kernel only consumed 3% of battery all night .
i keep wifi or gprs on for instant messaging needs. The Siyah kernel and the lulz governor give amazing battery life because process runs at lower clocks instead of jumping to 1200 unnecessarily.
The stock kernels aren't too bad in my experience.
I think you will find your battery drain will be caused by rogue apps before the kernel.
Edit: why have this phone if your going to turn off gsm and data etc. May aswel turn the phone right off and have zero drain overnight.
A drain of 1-3% per hour with everything turned on is normal for me.

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Well recently I bought the Beast S3.
Now I installed this first Kernel - CF-Root-SGS3-v6.4
And CM9 rom, was working great though there's one problem the damn battery drain is like being raped evey 5-10 mins if not less I loose 1-2% battery.
Now I though it might be the Kernel so I switched to Siyah-s3-v1.5.3-CWM, no go still the same result.
I changed my Rom to CM10, same result.
Here's a Screenie of my device (In Attachments)
Could you help out a little? I've checked and not sure where is the issue, and I understand that super huge screen consumes allot of power but even if I set brightness to 0-25% I get the same result...
Most battery issues are caused by installed user apps. Install Cpu Spy for cpu deep sleep issues and Better Battery Statts for locating apps that show unusual activity`s and drain the battery.

This battery drain percentage looks normal to me.
Sometimes I lose 5% without doing anything, even if I have a perfectly cleaned rom.
Hi, guys. At the moment I am using Johnny's CM10.1 ROM and everything works as it should, however, the battery life is relatively poor. The phone does go in deep sleep mode after the screen is off, but IMO deep sleep is not very efficient. I lose about 15% battery juice over night although CPUSpy does not record any CPU activity other than deep sleeping. Also, the phone is always a little bit hotter than normal. This problem should be kernel-related as it is not present when using a different one, such as Anryl's. Does anyone else have this same problem and if you do, how did you get past it? Please post your experience here as I've already mentioned this in the official thread and got no response whatsoever.
If you have FB installed it will eat up your battery, use the android sdk to monitor cpu usage.
