My battery life is for some reason very bad. I'm able to completely empty it in a matter of hour just with moderate usage... I had this problem before, solved it with Nandroid restore...
Now I'm running CM9 nightly (1/july/2012) with Siyah 3.3.2. When I disconnect it from charger, it almost immediately starts to empty.
I've tried to wipe battery stats and resetting fuel gauge chip when on 100%, but to no avail...
Can anyone help me?

Anyone?

Try flashing a different kernel but tbh it shouldn't drop that fast... Have you tried using a different battery?

Well, do you have experience with other kernels like Fluxxi or Dorimanx? Maybe it would be better with one of those...
And I havent tried a different battery because I dont have a spare one.

First, you may install Betterbatterystats, so it's easier to understand apk consume battery in the background.
Then you may install the new kernel siayh, the 3.4.1, it seems more parsimonious.
Finally install EXtweaks, excellent utility to set various parameters of the kernel.

No its not normal. It should gradually creep down not that steep drop. KI8 battery life is great... Among the other benefits. Someone with more knowledge may be able to explain whats causing that sudden drop. May be a faulty battery.

Man that is savage battery drain. Try something like smaberg's KI8 Rom with siyah kernel, I'm getting amazing battery life with that combination. Siyah also has some good advice on improving battery life.

Did you wipe your battery stats when flashing the ROM? If not, boot to CWM, wipe battery stats, charge to 100% and then drain that battery.
Goin to try that battery reset.
UPDATE: So I did battery reset but the phone has gone crazy. It suddenly started to automaticly switch to flight mode when I turn the screen on

Can anybody help? Where is the problem? I have only root and oficial cwm 4.. Thats all.

Have you tried changing governors?
Edit: so im little bit excited yet... Stock ginger roms are slow and have lags, custom roms are fast but they have some bugs - is here some normal choice? Maebe im going to flash back stock old froyo only with root and it will be all...
Adeclipse: On stock rom can I only use for example setcpu but dont any change... All the same... Even cpu spy showing all without change... I think that there is some problem with undervoltage...

Battery mod incorrectly shows battery is at 100%

I flashed a battery mod a few days ago, but today I've noticed that after over an hours use the battery was still showing 100% and I knew it couldn't be right so I checked the battery settings and it is on fact 91%
Why has this happened? I know I can restart my phone to correct this but I just want to know why it's showing 100 incorrectly because it could happen again and I'll think I have more battery power than I actually have.

When I restarted it now shows 85% when I in fact have 88% (shocked at how nearly 5% gone after a restart)

Can you give a link to the thread where you take the battery mod?
First guess: it only include the png file but not the modified xml file to make your phone using them...
I downloaded it from the 'Omega Files' app. It's the 'Mixed Theme' battery mod.
Sent from my GT-I9300 using xda premium
Should work if you use Omega rom but may not work properly on another rom
Which rom do you use?
I use ARHD but others had confirmed it working fine on this rom.
Can you recommend any others?
Sent from my GT-I9300 using xda premium
I still use stock rom so I can't recommend a custom rom as I have not use them...
You should post your issue in ARHD thread: if some peoples have managed to make your mod work with this rom, they probably could help you to find the issue...

Battery drain and high CPU usage problem

I have battery drain problem. All i did now is: full wipe/full format (system, cache, preload etc.)/back to newest 1-file 4.1.2 stock XEO ROM.
Nothing changed, all i can see is that my CPU is 100% usage, what is the problem?

my friend try to flash custom kernel like dorimanx 8.40 u get root plus u can oc uc uv if u need and phone shouldnt overheat plus u can try custom rom .
Sent from my GT-I9100 using xda premium
Tried all stock ROMs (excepting Android 2.3) and nothing changed, my phone gets overheated. May it be hardware problem? If yes how to repair it? My phone turns off my hands several times and maybe that's the cause.
first try custom rom stock or cm with custom kernel like dorimanx. if this dnt help try with different battery if this snt help could be motherboard problem. but first try flash dorimanx kernel on ur rom and check how phone behave

What ROM do you use? I recomend you use shostock3 v4, with jeboo kernel for me this rom and this kernel are the best combination to save battery.
Sent from my SGH-I777 using xda app-developers app
Before changing rom's, you need to install Better Battery Stats and find out exactly what's draining so much. Chances are if it's a rouge app and you inadvertently re install it on a new rom, you'll continue to have the same issues. Best to find the current cause before taking drastic measures.
Mine did this. Media sever was running wild. Check if that is the cause.

i was using shostock3 v4 itself with AJK kernel. flashed jeboo kernel and it turned out fine. BTW no apps was eating battery..looked like kernel problem to me...its SOLVED for now. thx guys
