Hi all
I was wondering why battery usage graph says phone has been once and while "awake" though "screen on" says it has been off?
What does that awake graph tell you actually? That S2 has been doing something behind the scenes or what?
I have the EXACT same issue but have yet to find a solution (though, I am on the Nexus S 4G)! I think this is what is causing me unnecessary battery drain since I am assuming that the blue bars associated with Screen On and Awake should correspond almost exactly.
While I know this post has not been helpful to you, I just wanted to tell you that you aren't alone. Hopefully someone will help us out soon.

same here, waiting for solution
A app has awoken the device from deep sleep, that's why it appears.
A phone can be awake while the screen is off. Some widgets may run/update in background. So its common, I don't see a problem in that.

Is there a way to check which app keeps the phone awake? I'm having this issue aswell, causing a battery drain sometimes.

Having the exact same issue with SGSII Litening ROM 2.2 on 2.3.4 KG1
Tried canceling Facebook&Twitter widgets and refresh rate
Disabled any dynamic widget
Disabled Live Wallpaper
Removed Skype
Removed TalkBox
and still no good, my phone wakes up for short intervals while screen is off and no use
must find a solution
I've had the same problem and was mad that what really kept running on background. But after I start using ATK it is almost gone. This is mine after 23 hours, before ATK it was a different story.

ATK didn't work out for me.. i used ATK Pro
I just found out that during idle(screen is off) the processes: 'suspend' and 'events/0' are waking the phone once in a while and using CPU
Does anybody know this type of problem?

I had the same problem and solved it.
I had the Location Services enabled. Disabled those and now it doesn't wake up when screen is off.
Hope it helps... It worked for me
Good Luck

I was wondering if anyone could give me some insight here.
I've noticed horrible battery life, and constant 200 - 600ma current draw. My awake time is absurdly high too. Then all of a sudden last night I noticed it was only pulling 50ma, and the awake time was staying low. Nothing had changed, no app updates, nothing at all. It just suddenly stopped having a wake-lock. Then this morning it went back to being wonky. So I finally gave in and did a hard reset, everything back to stock, installed just one app, battery monitor widget, turned on airplane mode (I thought maybe weak signal was a factor) and left the phone alone for a few hours. When I got back to it, the entire time it was pulling between 360 and 450ma, and the awake time matched the uptime (well, only off by a few minutes). To reiterate, this was with the radios off, and a fresh hard reset.
I really don't know what else to do.
I should mention this same behavior was exhibited on my first Evo3D that I swapped for a broken vibrator motor, so I don't think this is a hardware fault. Actually back then I thought it was normal, so I didn't think about it much, but then I got to thinking it's not normal for an idle phone to die in 8 hours with airplane mode on and no activity...
Thanks for any ideas!
Try downloading an app called CPU Spy and make sure you're phone is going into "deep sleep". If it isn't, I would start going through the apps through process of elimination by uninstalling each one and resetting the timer each time on CPU Spy.

Thank you, I'll mess around with that, but I think you have missed my point...this is happening with 100% freshly reset stock, so there is nothing to uninstall. The only thing is I haven't taken the .7 update, which might have a bearing on it.

Gotcha. Well, give CPU Spy a go. Also, I would download Juice Defender from the Market. I've noticed a significant increase in battery life since I started using it.

Nice app. I let it run for about an hour, it showed something like 7% sleep, 70% 384 MHz and the rest was 1188. I uninstalled the only thing, Battery Monitor Widget, then reset CPU Spy's stats and waited another hour...now it's 97% sleeping, 2% 384, 1% 1188. Looks like BMW was the problem. Thanks for the app suggestion.
Any kind of monitoring app will drain your battery more.
Locked & Loaded
Battery monitor widget doesn't show accurate readings yet. The guy that made it emailed me and said it should be fixed in one of the upcoming updates.

I'm with you on this, I think you're into something. I've seen the same behavior too a few times. Some days I'd be surprised on how good my battery life has been and some days I'd get pissed.
The other day mine was drawing like 400ma without doing anything (looking at the history of battery monitor widget). So, yes, I agree with you. Something funky is going on.

Did you also apply the OTA? I was having wake lock issues before applying the OTA and now that I did, the phone hardly drains over night after being unplugged.

Good to know. I have the two OTAs also. I uninstalled Battery Monitor Widget and I have noticed that it is draining a lot slower. so like the OP mentioned. I think that was the culprint. I will keep checking the next couple of days.
I noticed that too. Since the drainage ratings are incorrect... there is no reason to use it.

No. I mean Htc Sense sync. Turned that off and it fixed it for me.
I have tried everything. I tried various ROM's, SpeedMod kernels T27, T29, T32, and T39, and the stock ROM, and NOTHING is working! I cleared out my Dalvik and cache partitions obviously, and I caliberated the battery. Nothing is working!
I used the phone for 8 hours today, and the battery dropped to 50% in those 8 hours. I had the display on for 1 hour and 30 minutes, browsing Tapatalk and the internet. I made no phone calls at all. Besides that I listened to music for 45 minutes, but that's it. The rest of the time it was on standby in my pocket. This is running Lite'ning ROM v6.1 and Speedmod Kernal T39. However, no matter what combination of kernels and roms I try, the drain is pretty similar.
I have the stock android weather and news app set to update every 3 hours, and K9 Mail to fetch new mail every 15 minutes.
This is with Wi-Fi off, GPS off, and bluetooth off.
What could be affecting my battery so much? Is there any information I should post here from my phone so you guys could see what is causing this? I can't even use my phone for one day without the battery completely draining.
Well, you problaby already knew this, but the real life-sucker in the SGS II is definately it's screen. Get the brightness down low and make the screen timeout after 15 seconds so that you don't waste any unecessarily battery.
Can't help to much otherwise, just got my SGS II a week ago, still getting to know it myself. But hope that helps abit anyway.
There may be other apps synching in background. In my case fluent news trend to hang around. Check if every app is doing background work.

I can assure you mine is worse, drops to 50% in 6-7 hours, but as the other person has stated, the screen is the culprit, when I used the phone longer than you, I would expect worse battery life.
Gosh how I wish this phone was equipped with more energy-efficient, less bling bling screen. SAMOLED+ is only good for show-off, which I usually don't do.
Theres an app called betterbatterystats on the xda forum. Use that and see whats draining your battery, especially in the wakeloks department.
Updated Facebook? It's raping batteries so hard it should be on the 6 o'clock news tomorrow night. Or, you know, pretty much anything these guys say here.
Try to use Betterbatterystats and see partial wakelocks and cpu spy to see if you have any problem with deep sleep! Also take a look to battery usage and the percentage of Operating System Android

i definitely agree with this. i unticked the auto adjust brightness, and i set the screen brightness to the lowest value at all times (it's super amoled anyway, the screen is still visible even at the lowest settings).

Make sure you sign out of facebook chat. I had a funny feeling that the chat was keeping my phone awake. Turned the chat off and I have had excellent battery life since.

First of all I think you are wrong when you say OLED uses more power than LCD. Remember how these screens work, LCD lets light go through and is completely back-lit all the time while OLED screens emit light from pixels that are not black.
On the other hand, the real problem with SGS2, in my opinion, is the reason phone never goes to sleep. If you take a look at screenshot I attached you'll see that screen on my phone was not on all the time but battery drain continued. Also, "awake" bar is full meaning phone never got the chance to go to sleep.
I have no clue how to fix this, maybe someone with more experience can help. I use to have HTC Hero on which I could turn off "Always on" in network settings and get phone to sleep often and save battery that way.

Open up the facebook app, press on 'News' at the top left of the screen (to go to the facebook app main menu), press Chat.
At the chat screen, press the menu button on your phone, and select log out.
If you ever accidentally go into chat again it will log you back in. Just remember to always log out again. Do not use the back/cancel to get out of the chat screen.

Display drain about 1% every 4 minutes of browsing, this is in your case 22,5% .
Every 15 min email checking and the automatic update checking from other apps does the rest. There is nothing suspicious with your battery drain.

Bad apps?
I've had bad battery drain for the last week.
I've rooted, romed, unrooted, changed every setting I could. Nothing has really worked. I'm was losing between 5-10% an hour.
Then I just wiped everything and re-installed the stock 2.3.3 firmware and started re-installing apps an hour at a time.
Battery burn was going good about 1% an hour installing about 5 apps in an hour until I installed TM World Clock.
Within an hour I had a 10% battery decrease and Watchdog saying that Event/0 and Suspend were consuming the 90% of the CPU. I uninstalled...it went back to a 1% and hour battery drain for 3 hours.
Re-installed TW World Clock to see it was a fluke. Within 10 min. the phone dropped 2%. and Watchdog started sending warnings for Event/0 and Suspend again.
There might be certain apps that aren't allowing the Galaxy S2 to go into a deep sleep...explaining why the problem is so random among different owners pending on installed apps.
In BetterBatteryStats, under Other and Since unplugged, the no or unknown signal has been going on since the start of BetterBatteryStats. What does this mean? Is this draining any battery? I am getting perfect 3 bar signals.

It's just an issue with the app. Nothing to worry about.
But Remember: Task killers and battery stat apps drain battery charge

I noticed my S3 drains about 10% battery overnight. I dont think this is normal. Wifi and 3g are off, it just lies there by my bed doing nothing. Ive restarted it and no help.
Cell standby shows 41% usage. Is that right?
The 2 red circles in the screenshot show when my phone is idle just lying there.
Any help?
We need more information. What apps run? have you remove/freeze bloatware. Are you rooted? what rom are you on?
I'm going to run this based on speculation perhaps side effects of rooting your phone? I know there is no conclusive evidence of this but a hypothesis as such. My apologies if you aren't rooted.

why would rooting your phone create battery drain?
OP the standard answer is to install better battery stats and check it again to see what those wakelocks are. Once you find out why your phone is waking up you can do something about it.

install better battery stats and find what causes wakelocks......as above post!
Sent from my GT-I9300 using xda premium
thanks for the replies everyone, Im using the latest stock firmware... no rooting here...
Installing better battery stats as we speak and see what they say...
GSam Battery Monitor and / or BetterBatteryStats would be the first place as mentioned already.
I was able to find what was causing me most issues. It was some Calender storage and Google syncs (bookmarks, contacts etc) even though I didn't have them activated.
Anyway, after freezing them I now only lose 2-3% overnight. That is with gmail push, email sync every 4 hours and about 7 or 8 other Widgets updating every few hours. Mostly noticed a massive improvement when I flashed the latest siyah kernal.

I don't know but I get the feeling that rooting various phones might have hidden side effects as such, rooting your phone is still evolving as of today. There are still alot that the general doesn't know hence there are always new things about rooting although I might not be knowledgeable in that department. However is it possible to unroot your phone? rather revert it to stock? try doing that and see if there are any differences.
I have been encountering this problem since stock rom too. I m now using cm9 rom now. Battery falls rapidly from 40 to 0 evn on normal usage or during sleep. . I attached edited screen shot., please solve my problem.
It seems like a battery problem, not ROM.
what about battery.prop ?? i dont know about it. But some where i saw it helps for battery calibration. Is that true?

it is most probably an app which is causing this. just look at the image u attached. see the "Awake" bar and "Screen on" bar at the end. your phone was awake even when the screen was off for quite a while....both the Awake and Screen on bars should be very similar...else it implies an app is running in the background when the screen is off !!
thank you all for your concerns.
