I've noticed that when i flashed my SII with another Stock Kernel version than the one that came with the device battery life is much better , and no more unusual battery drain over night when in low signal areas , how is this possible considering both are stock and non modified only different versions ?
Because they're different, so they will be modified, just by samsung, not the devs here.

Hi
I am pretty much obsessed with battery life.
I have been trying few roms and I have yet to find the perfect one for me.
1) gingerbread 2.3.6 stock rom unroot
Performance wise is so so. Battery life, not what I expected
2) gingerbread 2.3.6 rooted
Tweak the CPU and does see a lot of improvement in battery life.
3) ICS stunner. 19
Great rom but I feel that the battery does drain a lot.
4) ICS cyanofree
Smoother compared to stunner but battery wise is worse than stunner
5) Gingerbread 2.3.6 rooted
Back to gb to see if there's any difference in terms of battery life. Better than the Ics
I do have a lot of my friends who are using the custom ics and their battery life is superb. I don't know why mine is bad.
6) stunner 19
Back to stunner again. Still feel the battery doesn't last. Heart pain when you have to under utilize the phone just to save the juices.
7) litening rom 1.0 (currently using )
awesome even thought that its not as smooth compare to the ics. Battery wise improved a lot but I am still searching for even better one.
Question.
Anyone using speedmod or Franco kernel before and could you share your experience especially the battery life?
By the way. The testing are based on my observation. It may differ from other people.
Appreciate it very much.

Hi there
i have my galaxy for a few wekks now and i find battery on CM9 RC2 pretty bad (underclocked and undervolted)
which rom is recommended for good battery life (and works with siyah kernel)
GPS/WIFI/MOBILE DATA/CAMERA must be working !!
thanks for your suggestions
I was using xwlpo stock, only rooted. Undervolted -25 and set cpu to 800 mhz. The governor was ondemand. The formula of amazing battery life. Now i use jelly bean which wastes battery.

No two people will ever have the exact same setup, and even if they miraculously did, the likelihood of their two phones coming out of the factory exactly the same is infinitesimal.
So a ROM that someone else experiences good battery life with, may be terrible for you or me.

Try rootbox with dm kernel. It has pretty good battery, but like previously said every user is different and therefore will have different battery life. It would not surpise me if this gets closed very quickly.
I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more
tks
It's a combination of both. The core power management drivers lie in the kernel, along with CPU frequencies, governors, and other battery life affecting things. But the ROM is what ultimately makes use of the kernel. If the ROM has certain battery draining features, then it will affect battery life negatively and vice versa. So it's really a combination of both.

buy another battery and carry it around with you
Hi, just wanted to know if i have the same application, the same usage with CM 10.1 and Stock lastest Sammy rom, which would give me more battery life ? :angel:
How much aproximatively would it be different if so ?
Samsung would be better.....10-20%
I keep reading of people using the phone while browsing for +4h of screen or surfing the web for 2h on 4G and still having 70% left of battery life.
This is all stock ROMs. From my usage this would be impossible, I'm using cm10.1 and on 3g I could probably go to 2h screen on but that's it.
I'm starting to think that maybe aosp roms don't even come close to stock ROMs (which I never tried though).
Some experiences between roms and battery life?
Yeah I agree that stock seems better than aosp based. Even using similar kernels (perseus on stock v devil on aosp)

yes.stock is better
Hi xda forum users...
I recently got cyanogenmod9 for my phone and the battery life is terrible.
Samsung galaxy gio
Moderate texting
Wifi on but turns off during sleep
No calls
No games
I really like cm9 but I also like battery life being longer

Ok I dont use ur phone so i am not sure if what i say might be accurate. From what i can see, ur phone was only supported my Samsung till android 2.3. Which probably means that your phone doesnt have a proper kernel for android 4.0.4 on which cm9 is based on. So probably the kernel being used isnt fully stable, hence ur battery life is terrible, I would suggest u stick to a gingerbread (android 2.3) ROM with a stable kernel to enjoy good battery life. It could also be that ur battery might actually be spoilt. Is there any slight bloating on ur battery?

The kernel which was compiled for the your phone might not be fully stable yet causing the battery drain. If there is a new version of that rom try updating to that and see if that fixes the problem.
