I have a i9300 and I really like this ROM, has everything i need except one thing: My battery is going out pretty quickly compared to previous ROMs i used (Foxhound for example).
I want to keep using it, so is there a good way to get better battery life? I'm using the default kernel that comes with the install because I dont know which ones would work with this ROM.
Any sugestions guys?
Thanks!

You can try to flash a Kernel that supports underclocking and undervolting of your CPU like the Temasek Kernel. Also keep an eye on what causes the massive battery drain. You can install a CPU monitoring app to see what`s using your CPU the most.
Also what do you mean by battery drain? Do you make it through the day?

It's not really a drain, but I barely get through the day.. while with the same use i would end my day with 40% with foxhound.
In the normal battery control it says its 40% android use..

Hey guys,
Since so much information is thrown around every day about battery life and dual core smartphones, I have a simple question that needs answering (probably a simple answer but I want actual clarification). Will dual core smartphone users see improved battery life performance in ICS? I thought this would be implemented in GB, but I still notice my battery tends to drain at a quick pace on medium use (I don't get the idle drain others do).
Thanks for the responses!

I don't see what a new version of OS would have to do with battery life.
What depends on the OS, is downclocking the CPU and GPU depending on hardware lock, and this is done already in Gingerbread.
At the moment you can get additional battery life using freezing bloat, using custom kernel with battery saving profiles and disabling data when you aren't using it.
I am having great battery life on my Atrix (2 days of solid use).

What do you mean by SOLID use? How long was your screen on? Are you on 4g? What apps do you run.. two days of minimal use I am assuming...

Nope, not minimal use.
Wifi on most of the time. Screen on for 4 hours. Music player on for 5 hours. Occasional GPS usage.
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 haven't been using stock ROMs for a while, and am now currently on AOKP JB, which is awesome. But I've recently had the need to be out of the house for an extended period of time, and i really need a ROM with good battery life.
So quick question, which GSM (or CDMA with GSM-patch) ROM gives the best battery life? I'm more inclined to think stock, and I've read that 676.226.3.en.EU gives really decent battery life. Or is there a better alternative?

Ive been using the simplex rom it has overclock and underclock scripts built in I have been on it for a few days and got 5hrs of screen on and 19hrs of power overclocked with 25% battery still left. Currently I am running underclocked to 1.0 GHZ to see how long Battery will last and sitting at 13hrs on battery and 4.5hrs screen on time and have 44% battery I think I'm doing well!!! No bugs yet either!!
SimpleX is for CDMA right? My bad, I should have specified that I was using a GSM phone.

i'm using magicmod rom, coupled with tasker to turn on 3g only when using data intensive apps like browser,youtube etc.. the rest of the time i have data enabled but 2g, and the battery only goes down about 2-3% a night, that's about 2-3% for 8 hours..
Hi guys, as title say, i want to know wich kernel is better for battery life..
I´m on Unlimited ROM, by mv style, wich is really awesome. I´m using Mesa Kernel, but i read that Panic Kernel is good for battery life too.. And performance is also good. So.. wich kernel do you suggest me? Is Panic Kernel more battery friendly than Mesa?
Thanks
My Phone is a Mini Pro
I have never used MESA kernel so I can't compare the two
But kernel PANIC has good battery life... Better than rage and Kamarush v3 (no offense) (just my observations)

Get battery monitor widget from market and test those kernels yourself.
It's better to yee for yourself then to blindly trust
It's easy to do, flash kernel a and leave the phone in standby during the night. In the mornign look at the battery consumption graph in BMW.
Then you take kernel b and do the same with it.
Just be sure to use the same min frequency and same governor.
EDiT:
A ROM also influences battery life. So let's say that for user B MESA has excellent batt life, for user A it might be bad.
That's why it's better to test and see for yourself

That's true....
Personally i try and aim to use a 'lite' rom + panic kernal if possible ....
But most phones give about 1 day worth of work. There are few that exceed that (ultimate? rom by mv_style)
Kernel panic has good battery life
Sent from my iphone5 using Tapatalk 2
I prefer kernel panic...in every way
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.
