Install BetterBatteryStats & let it run overnight again. You've obviously got wakelocks keeping the phone awake & causing the drain. BBS will help you identify these.
You can find it in the thread on here or on Google Play.

have installed BetterBatteryStats now.
i need to look at the "Partial Wakelocks" ? or where can i look for?
//
is there any problem? have made some screen captures !
You need to let your phone run for a reasonable amount of time to get meaningful stats from BBS (6-8 hrs/overnight in your case given the drain is happening overnight).
Edit to add - Yeah, partial wakelocks are where you need to look. Just having a quick look at those that alarm clock you're using obviously has a few, as does GTalk (doesn't mean you're actually using GTalk, this means something on your phone is/was trying to communicate with Google servers, and Facebook service as well.
I recommend having a look at the BBS thread on here & if necessary post your screen shots there. Guys who post there regularly will be more likely to be able to give you specific help than me.
Further edit to add - Don't waste time/money with 'battery calibrator software'. Everyone (should) know(s) it is not possible to 'calibrate' an SGS2 battery Also, Google have confirmed delete battery stats does exactly that - deletes battery stats. Nothing else. Has no bearing on/doesn't affect anything.
i can tell u the usual
try recalibrating ur batter through battery calibrator software wipe battery stats from cwm if u are rooted and try turning of 3g and lowering brightness
Have you tried a different kernel or cpu governor?

Currently on checkrom revolution 1.0 KI4 with hardcore's latest speedmod k2-8. Have had this phone for ard 5 months now and u can call me a compulsive flasher since I'm always flashing the latest roms, kernels and firmwares.
Throughout these 5 months, this overnight battery drain issue has been bugging me relentlessly, regardless of the firmware or rom used. Typically my phone will be off in the morning if i leave it at anything below 50% charge when going to bed. In contrast i've read of many accounts of sub 5% overnight drains that has lead me to suspect some kind of mistake on my part rather then a fundamental flaw in the design of the phone/software. Would be great if the xda community could assist by giving some insight into this matter, for in sure some of you might be/have been experiencing the same issue and might have solved it or are awaiting similar insight as well.

no its not normal. I lose 1-2% over an 7-8 hour period when im sleeping.
Install betterbatterystats and see what your wakelocks are over night. Something is obviously keeping your phone awake. The usual culprits are being signed into latitude or facebook chat.
i would suggest either change kernel or better yet change roms...kernel i would suggest ninp 2.0.5..stable and good battery life..also if you use setcpu i can provide you with frequencies so you can test it..message me so i can give them to you..regarding betterbatterystats i would not use but as skimmingstones say use it and see what your wakelocks are cause ur stats do not sound right buddy
Jeez! 40% overnight? I once had 8/9% drain overnight and got annoyed. Install Better Battery Stats first to see what apps/processes are causing the wakelocks. Then go on to change kernel and SetCPU etc for further betterment, but at first see what's going on background, with the help of BBS.
Post up screenshots of battery usage please.
My sister was loosing 40% each night turned out to be the Hotmail app not sleeping!
LOL 40 % !? your phone is the best drain phone ever :/
maybe U can set your display to low brightness and look of your phone goes to deep-sleep mode (CpuSpy)
Dude,
Try also to calibrate battery.
Look at my signature.
not normal for me lolz
Hie guys, I just woke today to see my phone was off and when I switched it on the battery was @17%, from the battery stats in settings it shows my phone switched off after 2hours of me sleeping. So what can really make a phone lose 74% battery whilst it's OFF??!!
Help me or you can paste me a link to where similar problems have been discussed.
Thanx.

Download a battery calibration tool off the market and use it, I have had this happen to me before where i would lose over 50% of battery life just by restarting my phone, and it would gradually go back up.
Also check if their are any updates for your rom and os you are running

Probably a pointless exercise since it's been proven you can't "calibrate" the battery in an S2.
I've had something similar happen, I was raping my battery with a torch app then restarted. Before the restart I had about 90%, after it was around 30%.
Could it be a sign of the battery failing? I've not had any real problems otherwise..
Perhaps you have wake locks? Purchase better battery stats or download it using the search button.
A high battery drain is often a limiting factor for a great user experience.
With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions:
- Spot drainers based on detailed information about the root cause
- Use the online Knowledge-Base to find how to reduce or remove the wakelocks
- measure the effect of actions to reduce drain
- detect changes in the awake/sleep profile and quickly find the causes (rogue apps)
I am getting some strange battery behaviour.
My device will turn itself fully off when sleeping about once a day. The power use graph often has strange jumps in it as well.
I've tried resetting battery stats but it's not made a difference.
Any ideas what could be causing it or how to fix it?
I've been having the same issue for the past few days. I've also been having a good amount of crashes. I am thinking about starting completely over: Odin back to 3.2, reinstalling CWM, and then trying the nightlies again. If that doesn't make it more stable, I may try Task 14 (HC).

Have you ever uv your device? It sounds like sleep of death.
And
If you're rooted download better battery stats from xda applications section and cpu spy from the play store to see your wakelocks and if your device is deep sleeping. Then post your bbs dump here

Well first, I would not recommend Juice Defender. I have heard that it causes the batter to drain more.
Secondly, the stats are only for not even 3 hrs. If you want a proper reading of what is draining battery it needs to be longer, if possible.
EDIT: What rom/kernel are you running? And did you do a full wipe when you flashed them?

I need an app that turns the wi-fi off when i'm not using it as I find wi-fi being creates a big battery drain. JuiceDefender has served me well for that purpose for years. Any other apps you can recommend for automatically turning off the connections?

Unfortunately 3 hours was the longest I could get before it turned itself off and the stats were lost.

I was running CyanogenMod 9 Nightlies Galaxy Tab 10.1 WIFI, then after a week switched to [ICS]Ganbarou GT-P7500/7501/7510/7511 CM9, and I am now as of yesterday on [JB][AOSP][ALPHA] Android 4.1.1 - Jelly Bean - [GT-P7510], full wipe as usual for them all, bar JellyBean where I had to return to stock first.
I've had the same power problem on them all, but i've noticed i've managed a 10hr stretch on JellyBean, so stats are attached.
Problem fixed.
I installed the Jelly Bean alpha, but it was still happening, so I drained the battery completely, then charged it fully, and that fixed the problem.
There are loads of battery threads(almost too many to get any useful info out of!) but I just wanted to check that there is not actually something wrong with my Galaxy S2 in regards to battery life so can someone please let me know what the expected battery life is when running the following:
CM9.1 Stable
CM9 stock Kernel
BVP7 modem
I have the following apps installed along with the standard gapps:
Facebook
Flipboard
BBS
CPU Spy
Flipboard
Whatsapp
Chrome
Titanium Backup
Dropbox
IMDB
Swiftkey 3
Viber
Twitter
Superuser
I have also tried the last 3 Siyah Kernels and pretty much the same battery life of about 14 hours max with between 2-3 hours of Screen on time before the battery dies to 0%!
In BBS there is about a 20% Kernel Wakelock constantly and about 8% Partial wakelock resulting in CPU Spy showing the phone never gets into more then about 82% deep sleep!
So simple question, what type of battery life are others getting with similar setups as I am starting to wonder if my S2 is actually faulty only getting 14 hours?
Thanks to all that take the time to reply...

I get 2,300 hours only of battery backup with those settings.
Actually, what's the meaning of this thread?
I think that's the average battery life with CM9, but we can't really tell cause we all have different types of usage
Did you let the kernel/rom settle so you could get the best out of it?

NO. Your phone is not faulty.
We all use our phones differently, we have different configurations etc.

You're expecting people to have the same apps and use the device the same way as you.. and then on top of that, find this thread and tell you how long their battery lasted??
I think that is VERY unlikely. Plus, there are already soo many battery threads, you just have to search for them. Good Luck.
Last I used, fb was a battery hogger. What about wake locks? Any major partial and/or kernel wake locks? The stock CM9 kernel is not so customizable, check out fluxii kernel or siyah..... 4-5 hours of screen time is possible, I'll link you to a thread that will help you save battery.
Edit: here is a thread from which I was surprised that my battery could do what I thought it couldn't.
http://forum.xda-developers.com/showthread.php?p=21851909 I followed the CM9 + siyah magic configuration.

Lots of apps that need sync don't help... betterbatterystats will also tell you if any apps are misbehaving.
Also checking the voltage of your battery to see of its faulty may prove rewarding.

I have tried the latest Siyah(with the config in the thread!) and Fluxii kernels now as well and still no where near 4-5 hours screen time!
The most I can get it about 2-3 hours screen time and about 14 hours of total battery time!
Right now after a full charge I seem to have lost 31% in 4 1/2 hours with 35 mins of Screen on time!
BBS is not really helping as it is saying i have 3% kernel wakelocks and 2% partial wakelocks but I cant seem to do anything about them after reading BBS threads for days!
I cant really believe that you have to do all this just so your phone can run for maybe 18 hours without going flat as coming from an iPhone4 I was able to get 2 days out of my phone before i needed charging so very disappointed in the S2 battery life.
Dear XDA-devs,
I have some problems with my galaxy S2, the major one is the battery lifetime.
When using the device, it drains superfast. I can not use the device for even 6 hours.
Because I can't afford to buy a new device I am looking for an solution.
I thought that it's a software problem and flashed supernexus rom but the drain is still there.
The overcharging ( 0% to 100% then taking battery out, turning off device and charging again) had no effect.
Battery drain (from marketplace) logs changes of battery status.
The log attached is a disaster.
So my question to you: How to track and solve the problem?
Thanks in advance,
Alex
I think its the kernel problem. Keep ur phone clean from unwanted apps which run in background, stop unwanted services such as wifi, lower the brightness, keep ur phone uc/uv as much as possible, try to be on stock rom as much as possible, increase the screen timeout and clean the battery. Thats all i can recommend

I dont understand the language in the attached pic, so thats not much help. All I can suggest are the usual suspects for battery drain.
Install CPU spy to check the various states in which the phone runs. Is it going into deep sleep like it should? If its not, thats your problem right there
Another thing to do is install Better Battery Stats (search the forum for the thread) and use that to check for unnecessary wakelocks. Additionally, I don't think what you mentioned (overcharging) is a way of calibrating your battery..although I could be wrong there.Instead you can use any battery calibration app, or if on siyah or dorimanx kernel, use the 'reset fuel guage chip' option in ExTweaks. else there are threads about calibrating your battery without the use of an app.
Or if none of the above works, you probably just need a new battery. Definitely not a new phone

Dear Alex,
have a look here => http://forum.xda-developers.com/showthread.php?t=1179809
It is BetterBatteryStats app thread.
BBS app is very useful to examine the battery stats and find wakelocks (prevent the phone from entering into deepsleep state) and alarms (activate the phone when in deepsleep state).
You can examine the BBS log yourself or just post your log and stat files to this thread to be checked by the "experts".
Good luck !
re
Hi HAXTREME,
thank your for the reply, the app shows the time when the battery decreases by 1%.
As you can see it loses 10% in some minutes ..
I will install the app the other poster mentioned and post results here..
thank you both.
// edit
although the wakesleeps could be a problem I would like to know why I can't use the phone permanently for some hours ..
as I remember this was possible when I bought it
Stats after tracking
Hello guys,
I have tracked the battery stats during 2 days now and it would be great if you could take a look.
Do you see something suspecious?
Do you need more information I can provide?

At the very top of your dump file you attached, it says:
Statistic Type: (3) Since Unplugged
Since 1 h 3 m 55 s
You need to let it run for longer than this after unplugging. BBS will reset stats and start a new dump file when you unplug the phone.
