I'm currently using lite'ning rom 6.1 with ninphetamine 2.1.3 kernel. the battery is better, but still drains quite a bit. I've heard people said speedmod hve better battery, while some said ninphetamine does. I'm confused ! Can anyone give me a proper answer ?

actually it depends of your own use of the device...
the best answer i thing it´s: test it and judge by your self..
both kernels are really great..
i´m using ninphetamine because speedmod still hasn´t BLN support and the battery drain its good...
but some times i spend it in two hours playing asphalt 6 lol
EDIT: also u can use SET CPU to changue the cpu freq, the user profile (conservative for example) and undervolt your device for better battery usage..

If I remember correctly, only ninphetamine support overlock rite ?

The answer is that their is not a proper answer .You have to try them all .
Kernel is not the answer to battery drain thats user apps .
Install one kernel test it for a week and so on is the only way otherwise its just rumour and poor testing .

Which kernal is good for CM7

I have been playing games on cm7 but it gets really to hot and the battery backup is also not that good. So guys which kernal can be good for CM7? ?
Sent from my GT-I9100 using xda premium
Depends on the game, but its normal to get warm/hot when playing for some time. All kernels are pretty good, so you have to just try them and see which is best for you. Have you tried downclocking the speed to 1000MHz?

nope i havent ..!
do you really need to ask what kernel is best for cm7...siyah kernel of course. Gokhanmoral as stated on his thread his kernel is compatible so why not use that
hmm. i also think Gokhanormal kernel (Syah Kernel http://www.gokhanmoral.com/gm/ ) or Speedmods Kernel (http://forum.xda-developers.com/showthread.php?t=1182498) might be good for u.

SpeedMod doesn't work on any AOSP ROM. So it won't work on CM7.

Asking which kernel/ROM/etc is best is against the rules and also it's lazy.

[Q] Battery Life with custom ROMs

Hi there,
i am new into this custom ROM stuff and i been trying few ROM and now i am on the UltimaROM 2.3.2
but Battery going down from 100 to 84 in short time
Which is the best to have more Battery
and is there anyway removing the default SMS app and use chompsms instead ?
Nothing is best here. Just keep experience yourself with different rom, kernel and tweaks to find the best battery performance for your phone.

These things depend on how you use your phone, but system and idle seem high on your list. Screen and talking are my top two. Batteries have so many variables. I would try different ROMs and kernels.

I am using the Stock Kernel but when i was installing the UltimaROM asked me which kernel do i want and had a list of kernels but where can i see what is the diff for each kernel ? i cant find such info ,

Go to page one General and you will find stickys .
Alternative is to read the kernel posts in development section .
Or even that new fangled idea google search .

I think stock kernal is probably your best bet for battery life...
Hi everyone!
1st post on xda, but I'm new in android world!
Anyway, I'm using Omega ROM v27.2 (JB)/stock kernel and I experienced some battery drain issues. After getting BBS, I didn't able to point out what was the cause.
After many readings, I found a possible solution: in advanced WiFi settings, they advised to disable "Keep WiFi on during sleep". By default it's set on "always". They advise to set it to "never" but I prefer set it to "only when plugged in". I think it's more logical!
I don't know yet if it's efficient but I'm trying this and I'll come back later to tell you.
Sent from my GT-I9300 using xda app-developers app
you could use phenomenal kernel for better battery life. it is better than stock kernel in terms of battery life but you need to check compatibility with the custom rom you choose
Foxhound Essential .2 with latest siyah kernel
Best Battery life I ever tried - I've used Foxhound, Criskelo, and Omega JB roms but the Foxhound Essential is the fastest, ram free (430mb), best battery life performance around (8hours extensive use with mobile date turned on). Try it its great! Thanks

Try latest siyah kernel - plus Foxhound Essential ver .2 - No bloatware and best battery life performance..
I flashed Phenomenal Extreme kernel yesterday but to test it properly I have to wait for Monday when I'll be at work.
I'm not a fanatic of battery life, I just want to find the right mix between performance & battery life. For now, I found the phenom extreme not enough smooth, I'll probably change it for the medium one in few days.

Get betterbatterystats and check the wake locks! The default battery stats from our phone can't allow us to deduce whether there is an issue

My best results with battery life has been with Phenomenal Extreme and VikingROM. I got about 6 hours screentime with wifi, sync, and lots of gaming. Though i think you can make almost any rom or kernel last about 5-6 hours screentime if you check your running processes and apps running in the backround.
I hv tried lots of roms
Psycho rom XXDLJ1 v 0.0.1 is one of the best
it gives u maximum performance and an amazing battary life
Though you can flash different ROMS and kernels to experiment with battery performance, most reputable ROMS like AOKP or CM10 Wong yield much difference. Too many other variables. I've heard Trinity kernel is a good one, but I just got an extended battery. I found it to be the most sure way of extending battery life.

I've tried omega Rom and phenomenal kernel but these didn't really give me any more battery.
I found the stock kernel and Rom gave me the best battery performance at around 10 hours with WiFi on and surfing internet and maybe a quick go of a game or two.

Siyah 4.1.5. and Neatrom lite works for me.
Speedmod latest GB kernel (I think it's k2-21) + checkrom v6. It's a GB though

Try this one, you'll get the best battery life anyone on here has ever had. I promise.
I use dorimanx kernel 7.11 + slimbean 2.8
In my case the battery lasts longer and it's stable and heavily customizable :good:

Seems all of them are the best. Gonna flash them all together.
The absolute best battery you can get is with Kernels that have MMC_CAP_ERASE enabled.Trust me. It might take you a while to find one but when you do, woah. Be sure to do a few data wipes after you've flashed the said kernel to get the most optimal battery life. I promise you it works, I did that and haven't needed to charge my phone for over a month now.

nice finding mate..
I would love to encourage Samsung to install this lovely kernel to all it's android line-up so we all can get benefit of life time battery life
Hi Guys,
I'm a new member so I cannot post in the Development Thread of the Super Nexus 2.0 ROM for the Galaxy S2 GT - I9100.
Galaxy S2's battery life is horrible as experienced by most people and I am no exception. So I was looking for a Good ROM with best battery life.
My search ended with Super Nexus 2.0 ROM. Its a very good and stable ROM. But its been almost a month since i installed the ROM but the battery life is almost the same as the Stock ROM. Tried some battery saver apps, but not satisfied. I would not like to change the ROM as its brilliant expect the battery life. So thinking of changing the kernel (Never done that before), so what do you guys think which Kernel is the best for Super Nexus 2.0 ROM and Battery Life.
Thanks.

Dorimanx kernel and mobile standby

I use a CM rom and recently switched to dorimanx kernel.
Since then I have seen that mobile standby is using a lot of battery something that had not been happening using CM stock kernel.
Any advice?

Its normal to have battery issues for a day or two after flashing a different kernel. Give it another day and see what happens. :good:
P.S. Next time you flash a kernel, use a kernel cleaning script before flashing. And also mention which versions of CM and Dorimanx you have now. That will help us help u better.
Yeah it happens with me as well.With 8.38,battery life was very good but with 8.39,it drains fast in standby.I'm using it for 4 days but battery life is same.
