So I've been having some massive drain since I've flashed slim bean. I ran battery calibration, that didn't seen to help. So I checked my battery settings and this is what I saw

What I can see is wifi on battery drains from wifi alarm on polls for times. Also Facebook apparently has instant notifications on and avast looks like it is checking on Facebook. That means 2 active apps running on wifi with clock running so system isn't going to sleep. Try limiting Facebook checks and do manual checks for between times that it checks. Smartwifi toggle app is also good as if you leave wifi area wifi shuts down saving battery. Alarm well not much goes on there but will wake device to make sure your alarm is accurate.
As a side note I am down to about 1% drain per hour on slimbean overclocked to 1612

I have always found the battery life to be poor but I have come to accept this device has a large screen and great processing power etc!
My UK phone is rooted on the latest ICS and has various apps frozen with titanium backup manager! It use to be in deep sleep mode for about 68% of the time but since 2 days ago cpu spy says it hasn't been in deep sleep mode! I have installed various apps that kill running apps but the phone fails to sleep!
Any ideas why it isn't sleeping, just sits at 200mhz!

AudioOut_1 and alarm manager appear as wakelocks in Better Battery Stats app!

Go to Settings -> Sounds -> Go to the bottom -> disable touch sounds. (Better if you untick all 4 options). Reboot. Leave phone for 10 mins. Check CPU Spy. :good::highfive:
Thanks for the reply, I did that when I first got the phone! Just checked and all the boxes are un-ticked!? Any other ideas?

Turn off custom power saving mode.. Check after that.. I faced issues with these two.. Sometimes even l2_hsic goes crazy and drains the battery.. Check that too.
Thanks, again this setting is disabled on my phone! Still sitting at 200mhz! Though the battery doesn't seem to be draining as much!?

hello sir..
hmm since i read that you installed various apps that kill running apps, maybe that is cause to kernel wakelock since your system always working to searching what app running and killed it in various time you set
..many system app that switch back on like google app no matter you turn off except you log out your account
or maybe you can try one off the famous airplane metode which is
- switch your phone to airplane mode
- turn off your phone and pull out your battery (until 10 sec or more)
- put again your battery and turn on your phone
- after complete reboot let it for a while then turn off the airplane mode
I had the same problem with audio_out one but only in imilka's paranoid Android.. Couldn't fix it in any way so left the rom..
the reason taskkillers are disputed is because memory works different on android. It reloads certain stuff afterbkilling it, causing a cycle of killing and reloaded that can cause more drain than is intended to safe

Recently, I switched from Oat's Light n' Tasty to CM9 nightlies (currently on 20121202) which I flashed with CWM. I have noticed that the battery drains significantly faster with CM9 when the device is asleep. Looking at better battery stats I found that ath6kl_wow seems to be the culprit, which was reinforced with GSam which reported that 89% of the battery was consumed by wifi. Any ideas of what may be the problem or how to resolve the battery drain?
Thanks.
Have you gone into the advanced WiFi settings and set it to sleep when the screen is off?
Additionally you could try increasing the WiFi scan interval in the build.prop

I want to be able to get notifications from the device, so ideally i wouldn't want the wifi off when the screen is off. I haven't edited the wifi scan interval yet, any recommendations on a time i should enter into build.prop?
You could try 180, but if you are always connected it won't make a difference.

Any kernel which gives good battery backup on cm 10.0.0?
Sent from my GT-I9000 using xda app-developers app
before changing kernel i'd start with uninstalling unnecessery aps with Titanium Backup (or other app) and playing with autostarts (switching off autostart of apk)
And change your guvernor from ondemand to smartass. Check for few days is there a difference. If not - i'd recommand semaphore kernel 2.6.5
That was cool

Thats what I did to extend battery life (I'm using CM 10 Beta 1 by Ivendor, great Rom)
-used BetterBatteryStats to identify partial wakelocks, which kept the phone from going to deepsleep. So I installed Google Maps because it always did background work and I dont need it anyway. I also deactivated Google Now.
-decreased screen brightness to the minimum, because display drowns the most energy. The minimum setting is bright enough for me.
-Yesterday I discovery the app Toggle2G, which switches automated to 2G when phone is locked and back to 3G when I enable the display. 3G is also very battery drowning
Today my phone is about 5 hours unplugged and I only needed ~4%
Of course things like gps, bluetooth and wlan (which I dont need at the moment are off)
Use betterbatterystats, find out what your partial wakelocks and alarms are. Look for any apps using too many. This is the best way to improve battery life.

Hi,
I changed the setting to turn off Wi-Fi when the tablet is in sleep mode. However, when I check my battery usage, it indicates that Wi-Fi is on almost 100% of the time.
Can I do anything to fix this?
Try better battery stats available here at XDA. Although it's designed to help you find out what's using your battery, the info the app produces will show you what programs are running the most. Odds are one of those uses wifi and that's what's keeping it on during sleep. Just remember that you'll need to be on battery and not plugged in or docked to gather the app usage info.

Definitely an app keeping wi-fi awake. I have mine set to never turn off during sleep and I only lose 3-4% overnight. Wakelock Detector is another app that can identify which apps are keeping wi-fi active.
Thanks, I'll try to see if these apps can diagnose the problem.
So far with testing battery on all roms, including stock, the phone hardly ever goes into deep sleep. Here is what I have so far on bell stock with arrrgh's kernel.
All roms seem to have the wake spasms.

Do you use Facebook or social media apps? They're known for keeping phones from entering deep sleep. I could speculate more, but only because there are quite a few apps out there that can give the problems you're having. Usually ad heavy apps.
PAC, with just the rom and gapps, has no issues with deep sleep. Carbon didn't either. Wasn't on carbon for very long, but the stats reflected my screen off times. I'd post a screenshot, but its been on the charger since boot, and they don't deep sleep when charging.
I do but I honestly expected smart actions' data limit to prevent that. Would turning their sync off fix that?
Edit: just tried disabling Facebook sync and still have wake spasm.
Edit 2: just bought better battery stats and over a 1 hour 43 minute period, 46% was deep sleep. What does the awake bar in battery stats in settings mean then?
