ROM for best battery life !!! - Galaxy S II General

It has been some time since we have talked about a ROM to have the maximum battery life..
With normal usage through the day that includes data, music and talktime..
Everyone please write the ROM they think provides the best battery life.
Cheers.

It's against forum rules to suggest ROM's. Here's the post stating such rule:

Best battery life possible? Ultratoxic, Gingerbread ROM. Best battery ICS ROM? Slim ICS. Siyah kernel for both, plus you can undervolt more aggresivly on Gingerbread. So basically, the less resources and **** there is, the less the phone has to worry about.

I think I have seen some posts related to the same so there shouldn't be a problem.

the best rom?

I currently have darky's rom 3 installed and right now im kinda disappointed as the only real difference i've noticed is loss of battery life its dropped around 25% for no apparent reason. So i was wondering what kind of roms you guys have installed and what benefits are you getting from them? im thinking of taking away darkys and replacing it with new one, failing that i will just remove it altogether.
They all the best to each person who uses that Rom as every rom usage will be different from person to person.
the question is Which Rom is BEST FOR YOU??
try them all and choose whats best for you... we have different taste and preference... Enjoy your Journey
Depends on whether you still want Samsung features or just pure ics like cm9. I'm currently using slim ics debloated and 450mb of free ram.
I love checkrom since the galaxy s 2, it's awesome on the galaxy s 3. Very fluid with awesome battery life.

I'm not sure you're going to be significant gains in battery life with CM10 in its preview stages (I certainly haven't, and i'm quite conservative), but i've been using Siyah 1.3.8a since the latest preview build and it's brought improvements across the board for me, most notably in speed & audio.
To be honest, I wasn't overly taken back with the animations & 'Project Butter' thus far but that's all changed with the introduction of Siyah! : )
Closed, "best" anything threads are unwelcome.
Also there is a damn CM10 discussion thread, use it.

GB ROM vs. CM10 ROM on battery life?

Someone said that the Touchwiz 4 or GB ROM is better on battery life then CM1? Is that true?
Sent from my SPH-D700 using xda app-developers app
Battery life depends on many factors.
Try all the available roms for yourself. Anyone can give you an answer, but that doesn't mean it applies to your specific device and battery combination. With regard to battery life and custom roms on any device ... YMMV (your mileage may vary).

Exactly this... there are so many factors on battery life that comparing battery life from one person to another is pretty pointless... but trying the roms out on your phone is a good way to test because you will mainly use your phone the same regardless of the rom you use... so the only way to really tell what is going to have better battery life for you is to flash the roms and try them all out for a few days each....

Thanks . Someone said it depends on the software. But Idk. I only tried CM9 and CM10 because I always loved ICS and JB.

GB Roms definitely have better battery life. Stock touchwiz fc09 rooted running shadow kernel gives a whole days worth of charge with 2 hour screen time. On cm20 you can watch the percentage drop as you use it, doing that on stock fc09 is like watching water boil lol. It also charges faster. 1 percent about every minute.
Of course, YMMV but this is my personal observation. I'm running cm10 cuz I like jb, but once they fix battery drain it'll be great. I know its possible cuz the battery lasts a lot longer on the night lies than the first unofficial and official preview builds.

My general experience is the same but on cm10. I typically get 3 hrs screen on time, 20-30 minutes of calls, 20 texts or so, usually an hour of game time...and about 18 hours total up time...and I am at around 15% at the end of the night. That was with the 1012 nightly. So it is definitely a YMMV thing! This is on a epic touch 1800 battery.

I haven't messed with my phone in forever. I currently have a CM7 nightly running on my Epic. Can I just flash a CM10 nightly or will I need to do something first? Like update clockwork mod or flash a different kernel <-- you can see my ignorance showing here.

I was running CM9 when I flashed CM10. I think you can just flash it but I am kind of a newbie. Just do a bit more research. And if you flash cm10, you have to odin back to stock, root, and then flash another ROM you want to flash something besides CM10.

When I jumped from CM7, I went to mounts and storage and wiped everything in there except /sdcard. Then I flashed the ROM and appropriate gapps, and all was fine

If you want to stick with CM10, I've found that the SimplyCM10 kernel actually helped with battery life. YMMV, but I was draining 1800mAH in ~10 hours and it's >12hrs the last couple of days.

I have 1500 mAh and I go to school with 100%, come home with about 40-20% and to me, that's unacceptable. I never flashed kernels because I never thought they really did anything.
Sent from my SPH-D700 using xda app-developers app
If battery life is a major concern for you, then probably avoid CM9 and CM10. But what you get in trade-off is amazing performance and features that only Jelly Bean has. I have a charger or two at home, one in the car and one at work.. plus a couple extra batteries for emergencies. So having the battery last 'all day' just doesn't mean much in my case.
I'm not too concerned with battery life, cause I have 2 stock 1500mAh batteries, and I usually carry around a usb cord in my backpack just in case.

Best kernel for battery life?

Hi all
I'm currently running Cyanogenmod with faux's kernel and getting pretty good results, just wondered what other people are using to get great battery life?
Thanks in advance
Sam

No such thing as a best kernel. Some phones like certain kernels more than others. Experiences vary.
If you're looking for kernel suggestions I'd go with Franco or Trinity by morfic (Google to find his kernel as it isn't on xda).
Sent from my Nexus 4 using xda premium
This is really subjective and is something you would need to test out on your own to get any solid answers since there's so many factors that could affect the outcome.
Thank you but it was just to see what others recommend. I've heard good things about the matrix kernel
Sent from my Nexus 4 using xda app-developers app
Also when using those kernels download the app trickster mod it'll let you customize the kernel settings but don't touch anything you don't understand because you might mess something up. Franco and morfic have paid apps that customize their kernel but trickster is a free alternative until you commit to one kernel

Franco or Matrix...But while using Franco Ive seen a big difference in battery and thats just my experience with it but like the others say just try em out and see wats best for you my friend..

Agreed. Franco really knows what he's doing, no offense to the other developers. Morfic is another good developer.
Wasn't a huge fan of matrix on the Nexus S. Just my personal opinion (don't attack me because I prefer one kernel over another!)

Nothing against math kid but (not saying he does this) but there are some shady developers or Rom cookers who say they added their secret special tweaks to boost speed or performance. I don't believe it because it's placebo. If there's no proof in the source then it doesn't exist.
Franco actually says what he did, and you can see it in the results. Plus he's very adamant about replying to feedback as long as it's not a silly question like "can I under volt using this kernel???" There's a reason why he has 20k thanks
But either way enough of my rant. Hope op finds a kernel he likes. I'd start using the most popular kernel out there and use it for a couple of days. If you aren't satisfied then try another. Satisfied but want to see if you can do better? Go ahead and try. They're all free anyways, the beauty of xda

Franco doesn't support undervolting because,
I answered that the last page. UV comes when I think its a good time for it. I do my own thing, not follow what other people do on their kernels.

I really don't care much about undervolting, I think in the end its more placebo than anything. Sure it might help a little bit, but not as much as users think it does. Aggressive cpu frequency management, core management, now thats where true savings come from in my opinion.

I don't really undervolt my phone and have pretty good battery life as it is. I didn't undervolt on my Galaxy Nexus either because it had something called Smart Reflex undervolted for you when necessary. more info @ http://www.ti.com/dsp/docs/dspcontent.tsp?contentId=52746#a18
---- Franco isn't saying that there won't be UV support but as of right now he's focused on other things and will add it when it becomes more stable. And I agree with him on the second part about there are other parts of the kernel that can be worked on to have better battery life rather than just having people UV as the solution (for now).
Edit: there's a reason why his thread on GN has Views: 4,859,042 http://i128.photobucket.com/albums/p163/gbd270/views_zps2644eff7.jpg
Even there's no UV on his r14, this kernel is very stable and I've a (very) good battery life
I really appreciate all your responses, so what settings do you recommend for best battery life on Franco's kernel?

If takes a couple of recharges for the kernel to come into effect. Have to give if a few days for your phone to get used to it.

The only real flash and forget kernel is IntersectRaven's. Bare bones and full of awesome. Faster than stock kernel, and better battery life. Also stable as a rock. My last up time was 100+ hours.

Go to Original Dev forum and look for kernel thread on the first page, that's your answer.
