Im using slim bean and siyah kernel and noticed that I get battery drain. I kill for night all apps but 10percent drop in night.
Install better battery stats from Play and see what is causing the problem
I used better battery stats but it not showing what cause the problem :/ when I see that battery getting drained, I reboot phone and then it fixes :/ maybe some app it causeing it
Look for kernel wakelocks and partial wakelocks
Please provide the info from bbs so we can try to figure it out.
Depending on hnw long you sleep, 10% is less than 1.5% drop per hour which is not the least you can get but also net the worst.

I noticed 17 hours up time on his stats, and about a 20% loss, so I'm inclined to agree there, nothing too drastic at all
this is logcat from bbs and dump from both, kernel and partial wakelock. I still get drain like this.

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
Stock battery
I have done everything from Autostarts to managing my processes constantly. I played hanging with friends, got on here, and texted.
I posted an updated battery usage. I have lowest brightness, lowest image brightness, 15s timeout, etc.
i would probably switch to conservative governor vs powersave
This isn't typical battery life
I'd advice you to use better battery stats and cpu spy to se what's causing your battery to drain so quickly
Sometimes I notice "back up" in bbs, and this casus my phone to drain within a day
Hanging with friends does consume a lot of battery, but I play it too, and this does not cause that much drainage..
I have ICScrewed and with a heavy usage, my phone usually last for 1.5 ~ 2 days
With moderate call/text and idle, it lasts for 4 days.

Dang that is high! Are you sure about that? :O At medium usage /w unnamed i only get about 18 hours total. It was similar with ICScrewed too
Holy crap. I'll look into better apps. Could UnNamed be the culprit? Or the kernel?
Should I buy a new battery? The life waslike this for the few days I was stock, I think
I average around 17hr, on a good day I'll get 20h. I also recommend better battery stats, great app to see what's keeping your device from going to deep sleep.
Another great app is lbe privacy guard, you can deny certain apps and games some of the permissions they want (disabling GPS on those that really don't need it etc).
I'm on unnamed so that isn't the issue. Might be the kernel, just check the kernel wake clock in better battery stats to check. I'm on entropy's latest dd, while i do feel i got better battery life on the kernel with the latest unnamed ROM I'm not to sure if it's the kernel or something else.

I'd be curious to see your graph. My battery is dead now, but tomorrow I'm going to get on and upload Better Battery Stats to my phone. I would've paid for it on the Market, but I couldn't find it when I searched. I'm curious to see what other people think. I switched all Powersaves to Conservative. Is OnDemand bad for my CPU as it constantly trips from 500MHz to 1.2GHz? Should I consider going to 1GHz?

I have a hard time believing that. I've done everything I can to optimize my phone and reduce wakelocks and battery drain, and I still never get more than 20 hours on a good day, and that's with moderate usage.
How do you define "heavy usage"?

I agree. This is my latest battery cycle of what I consider "moderate" use
What I'd consider light usage (about 10 minutes of voice, between 5-10 minutes of cellular data, 10-15 texts, and about 20 minutes of total screen-on time) I get about 35 hours.
I have managed to almost completely drain my battery in about 4 hours though... Thanks Game Dev Story!

I realized I forgot to turn off data when I'm not using it, but I installed better battery stats and I didn't really see any wake locks. Should I try a different kernel? Any opinions on an efficient one? NOTE: I already got the yellow triangle for using the Odin way, so I'm fine with doing whatever to this phone.
I added my better battery stats shots. I guess today would be called a very light to light day.

I see two very top wake locks have kept your phone from sleeping for an hour..
That is a significant amount.
Also, use cpuspy to see how hard it's been working.
I would try to get rid of those top two wake locks...
Oh crap! I didn't see them until you brought it to my attention. That explains some of the idle drain. I'll look into CPU Spy. You guys have been so helpful!
Your kernel wakelocks had no data, probably due to BBS being a fresh install. A full charge should set a proper reference point.

If something's holding that many log wakelocks, something might be spamming a log somewhere.
I can't find anything to help with those two either. Or would seem that the keyguard might have something to do with text messages, but I can't see anything that would spam the log. Where might I be able to read this log?
Also, I'll post my CPU spy stats toward the end of the night. It's looking like it spends most of its time at 500MHz.
@wrathofnero You can remove the triangle with a usb jig. Worked for me.

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

Titanium Backup

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.

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.
hey guys
I am having a lot of problem with custom ROMs. please help.
Every custom ROM i install, after the very first charge cycle the ROM lasts extremely good for one full day with my complete usage as well. but as soon as the second charge cycle is finished it doesn't even last 4 hours whether i use or not.
I install only the regular apps and hardly 5-6 of them.
please post your valuable advises and suggestions.
would help
thank you
You need to recalibrate your battery dude.
Let your battery die.
Then with your phone off charge to 100%.
Then remove battery for 5 minutes to reset fuel gauge chip.
Replace battery, turn on phone and enjoy

still the same problem
but when on stock ROM, the battery runs all good.
That's because battery 'recalibration' (at least these batteries) is voodoo nonsense
It sounds like a process(es) is causing wakelocks which is causing excessive drain when the phone is idling (from what you've described).
Get BetterBatteryStats from Google Play, then read the BBS thread on here (search for it; if you can't find it, you can access it from within the app from memory). That should give you some clues to help you track down what's causing the drain. If you're still stuck, you should be able to post stats/screenshots to the BBS thread & I'm sure people who post there regularly should be able to help you.
I disagree with your statement about battery calibration being nonsense.
Do some research into the battery gauge chip in the S2 dude, resetting it definitely works
You're right though it could definitely be wake locks too

I used to have a similar behavior. I bought BBS and found that viber was having many wakes, uninstalled it and things were better. Google services sometimes also drains battery, deactivate wifi and data and verify if battery drain continues.

Maybe you are right. ill look into it
You can try GSam Battery Monitor:
https://play.google.com/store/apps/...?t=W251bGwsMSwxLDEsImNvbS5nc2FtbGFicy5iYm0iXQ..
It is easier to find an application that consumes juice in GSam BM than in BBS. BBS is very good but more difficult. I think your problem is beeing made by bad application that sucks energy.
You can also try CPU Spy to get known if your device goes into deep sleep mode.
Try turning of location services. It will help but there must be something else too. Did you try CPU spy which shows how much time your phone is in deep sleep when not in use?

I've been having really horrible standby time lately, like 4-5% going down overnight. Didn't take big notice of it since I used GSam to monitor battery drainage and everything looked normal in there with no wakelocks or anything. But just got myself Better Battery Stats to check out and confirm, got rid of GSam and bam, I've lost like 1% max overnight!
So if anyone has this installed an experience battery drain, I would highly recommend to get rid of it. BBS is worth every bloody penny.
