for best battery performance, If you want to use sense ROM then use ARHD with Stock Kernel{ usually get more than a day's battery and more than 3 hours screen time} or Maximus ROM with franco or faux kernel{ some people reprted 4 to 5 hours of screen time } though have not used MAximus ROM myself...
Use faux or franco kernel with CM10 or AOKP ROM
these custom kernels improve performance as well as battery life
At present i am using CM10 with franco kernel with more than a day's battery and 3hours+ screen time
Sonn gonna try again Trip's CM10 and his new 3.1.10 kernel

In my personal experience for best battery life use a Sense ROM (Stock or modified = ARHD, ViperX etc..) with stock Kernel. Have tried a couple of AOSP JB ROMS few weeks back but battery life was not as impressive as on sense. Standby times on sense ROMs are fantastic.

My recommendation is ARHD with stock kernel

ViperX 2.0.1 with stock kernel. Just wow, just wow.
Sent from my now amazing HTC One X thanks to TeamVenoms ViperX rom

For some reason Sense ROMs do better when it comes to standby battery life, or so I've read.

I guess he meant saying battery life on viperx 2.01 is very very good

I'm intrested how long it means :silly:
smidgeox Can You say something about battery life?

Well I am using viper 2.0.1 with stock kernel and game kinda lags. Can anyone suggest a kernel with viper Rom which will give Me optimum battery life.

Sorry, haha i was that happy with it
With ViperX 2.0.1 i've once got near 5 hours screen on time with i'd say constant use (however i should add that i had the brightness quite low)
Also i've once got 26 hours out of it that's obviously with standby/sleep

Man, just stop it. You can't get like a week of battery life out of this. And you are expecting a kernel with better performance but also with better battery life?

You want non-laggy games yet you want optimum battery life....? Whatt..??

All I meant was a good kernel with decent battery with 3.5 hrs of screen on. I don't live in a lala land that I would ask for 5 hrs of screen on.

TBalden's CM9 beta 5 with his kernel with the multitouch fix. Best battery life ever.

Until HTC releases the 2.17 source, we're stuck with the current batch of custom kernels. With no new source, devs really can't do too much.

What ROM/Kernel do you use for best battery life?

Hey all,
Just wanted to see which ROM/Kernel everyone is using. I'm looking to get the best battery life I can. I'm currently using Sammy but I've heard that the stock kernel is good as well? I'd love to hear everyone's recommendations and suggestions.

I'm using the current AOKP (actually i haven't installed the update from today yet) as well as the latest Ktoonez's KT747 kernel and have nothing but great things to say about the battery life. The KT747 also comes with Ktweaker for overclocking and undervolting which when balanced properly can increase performance all the while actually improving battery life.

Kernal

Hey guys I'm new to galacy s3 n new to Samsung. I just got rooted and now I'm trying yo settle down.. but I still need a kernal.
I'm looking for battery life and performance. What kernals do you recommend?.. thank you for the help
*Sent From My WickedBlueGs3!*

You need to give more info, what are you running I see in your sig wicked so I assume Evil's Wicked rom. Like I tell everyone else, a kernel is something you need to tinker with your self. Some settings that I use may cause your phone to not even boot up. Make sure you flash the proper kernel that is for a 4.1.1 touchwiz rom and play around with settings from there.

I've read that this kernal boots at 1.9Ghz and that it causes the phone to overheat. Which can end up killing your battery in general.. im at 23% with stock kernal after 13.5 hours. Which extremely good consider I used to get maybe 6 hours on the HTC rezound.. But if I can improve it that would be EVEN BETTER lol that's why I'm looking for a kernal.

Also the kernal that came with the rom does not allow undervoulting.. :/

KT747 Questions!

Hi all, i am currently running tasks aokp rom (latest). I am on underwear and wanted to get KT747, hearing a lot about it! So I have a couple of question!
1) Is the aosp version for aokp as well?
2) How is the battery life if combined with tasks?
3) which governer would be the best for a noobie like me?
4) How is the battery drain on idle (how much percent per hour)?
5) I read that if I flash this kernel and try to go back to rom I have to reinstall the wifi and Bluetooth drivers, How can I do this (what are the steps in case this does happen, so I know before hand)?
Thanks in advance!

You should spend a few hours reading in this thread.

1.) Yes
2) Battery life and kernel performance/response will always be device dependent and vary dramatically from device to device.
3) If you're using KT's kernel, I suggest using his governor, Ktoonservative. KT even shared his own setting recommendations in his thread.
4.) Idle battery will again vary between device and settings, but to give you an idea, I had about 10hrs of battery time , 1hr15m screen and was at 67%. So, in my personal experience, battery life is phenomenal.

What do you mean by stock? Your custom ROMs stock kernel or stock as in TW stock?

So if I flash the stock rom, its taken care of!? I'll check to see once more. Also can I get the kernel and not mess with any of the setting and still be fine? Like keep it all default?

Keep it default meaning what the kernel governor, scheduler and voltages, etc are when freshly installed? If so, yes. Though the beauty of the kernel is the customization and control.
