Hey guys the reason im making this is because i have seen on other forums and even on this that alot and alot of people ask for which rom has the best battery life. So in solution i am making this poll so that people can just look at it and not have to create a thread on what rom has the best battery life and clutter up the general.
SO here are the roms
I will update when new roms come
*snapshots would help
*other roms comment
*choose 1 rom only
*why and how much would help to
Best battery life for me has been Saurom GB. 13 hours on battery, 6 hours of screen time.
On ICS, I've gotten 8 hours on battery, 5 hours screen time while on Noteworthy Beta 2. Still have some tweaking to do on ICS, I had a couple apps set to refresh every 10 minutes, so it killed my battery faster.

Guys a Search would have told you that Battery life is 99% on the user and has almost nothing to do with the rom. We could be running the exact same rom and get very different battery lifes due to the apps we use and how we have the device set up.
In the end there is not best rom. Only what works best for you.

Hi guys sorry for this thread new here so please go easy on me. Had a galaxy s2 for a few weeks now and i have to say best phone ever. Did the normal rooting and flashing roms and i have noticed recently that my battery has been going down quite a lot after a few hours. I tried roms like Villainrom, Cognition, Batista and etc which i find them very good but on my battery stats it says that i have high display usage and the percentage is like 56 - 85 and sometimes goes and stays to 91. i have since then when back to 2.3.3 stock firmware rooted it as well and i only have display percentage of only 25% which i think is normal and my battery lasts longer. I have spoken to Samsung regarding this situation and they are sending me a new battery but im just wondering why i cant flash a custom rom without having to worry about the high display % and what can i do to fix it? do i have to give it a few days for the battery to settle on the rom or shall i just stay with the stock rom for now till i get my new battery and then try to flash? sorry for the long essay i just need to find out if any one else had the same problem as i really like to use a custom rom that my normal one.
THanks
I too find it very hard on the battery with all the custom roms that I have tried out. I tried, Villain, Cogniton, LeoMar, Batista, etc..etc..etc. I have in fact tried out all the ROMs out here. Tried even different combinations of Kernel, but all only lead to the frustration when it comes to battery life. I finally tried MIUI ROM and I can say that it is giving me very good battery life compared to other ROMs.
It is interesting to note from you that the STOCK ROM has given you better battery life. Could you please tell me how long did your battery last in Stock ROM and what are the Apps that were running in it?
Install Better Battery Stats, I don't think anything wrong with the battery.
See under Wakelocks what apps/processes are going in background and causing the drain. Then take necessary steps with TB Pro.

to xdadeveloporian: thanks for your reply bk and sorry to hear that you had the same issues. like i said above i am very new to all this so apologies if i am replying with noobish comments. with wifi on and the normal widgets i had a battery life over a day. only charged it once and it still going. is that rom that you using now good?
and to ithappy sorry what do you mean by your reply i do not understand sorry. and do you guys think with a new battery it will fix my problems and i will be able to flash roms or do i have a faulty phone?
% is not important, what really matters is total time on for the display. Are you sure it isn't that the stock ROM burns more power in other areas, so the display is less? Or maybe the brightness is different? I'm not even sure how the display proportion of battery drain is apportioned - is there really a current sense integrator?
now that i have the stock rom with firmware 2.3.3 display is 30% followed by android os 15 - 19% which i think is normal into regards were i was on customs roms and the os was 15% and display 50% and over. brightness is basically at the lowest i can put it i am using touchwiz launcher and i only have two pages with widgets and nothing else. just a bit confusing thats all. i mean with custom roms the battery should be alot better not the other way round if you get me.
apologies if im not making any sense here. thanks again for all your replies it does help

I don't believe that stuff, why battery life would be better in a Custom ROM, because they added/modified some stuffs, nah. You can make a Stock ROM custom with some little modifications if you are rooted and have great apps like Root Explorer, Titanium Backup etc. I, for me, will never ever use a Custom ROM. But that's just me, don't take it any personally.
And about battery, don't see that how long are you getting with it, like- 1 day, 2 days, they don't make any sense, just keep an eye on the 'Screen On' time, if that is around or above 5 hours then you are very fine. And also keep checking that your Awake and Screen On bar is synchronized or not, if it is not then you must have something going on background, like- Latitude, Email exchange etc. which you can see under Better Battery Stats. And also, when not needed turn off, 3G, Packet Data, WiFi, Auto Sync, Background Sync and check how many apps are on Auto Sync, if not needed then modify it to Manual Sync.
Regards.

Maybe they fixed some bugs - specifically a custom kernel might have improvements or bug fixes (since there is lots of work going on here from many companies making contributions). This takes time to filter through to the official ROMs.
Maybe they removed some of the stock apps which contribute (maybe only slightly) to power drain.
Maybe the small differences in the ROM mean that existing bugs are less likely to have an impact, so even not fixing the bug it seems to have gone away.
Custom ROMs are as likely to make things worse - but if many people are affected then it is likely that someone will track down the reason.
Look all i know is that as soon as i started flashing custom roms on my phone my battery life has been going down like hell. Checking battery stats the most thing that is taking up battery life is the display being as high as 80 even 90 percent. I am not a expert on android having had an iphone all my life so when people say underclocking and other stuff its like new things to me so i do apologise for being such a noob. i do love my galaxy and i think its the best phone out there at the moment. all i need to know is if there is something that i can do to bring the display down and not to have it drain so much out of the battery..
Thanks again for everyone for replying
very niceeeeeeeeeeeeeeeeee
huh? has anyone else experience high display usage on their phones when checking battery stats?
is that from the android market i can get that app?

I didn't find anyones questions regarding the best rom for reception and battery life. I find that my phone goes into roaming mode a lot, and I was wondering if there are some roms that would replace the modem in my phone and a rom that would increase the battery life.
thank you.
Either your in an area where your service sucks or its possible you have a faulty phone. I've read complaints about some phones have horrible reception. ROMs wont improve your signal and data.
As far as battery, everyone seems to find their own method on what works best for them. Most of the roms are cooked with battery consumption in mind. Using set cpu to underclock while the screen is off is the most popular user method. Some roms have clocking settings already set to the devs liking. Youll just have to read through the development forum to find what roms have the features your looking for.
Also having low to no signal and roaming is probably the main reason your battery is draining fast.
oh I will check out some ROMs. My phone lasts about 8 hours with moderate use. I wish it lasted at least 12 hours.
What do you think the best ROM for battery life is? I've tried checkROM and wasn't too happy with it, due to the fact that the battery drained a lot while playing music - which is one of the main features I use on my Sgs2. Next I moved onto VillainROM, it just wasn't to my liking, as of now I'm on the beautiful HyperDroid-Androidmedia VXD and I'm loving it, I've noticed a fair amount of difference in battery life, 5hrs display time along with a lot of wifi, games, eveything, so I'm pretty chuffed.
I'm going to check out MIUI - but how's the battery on it? I've also heard that it isnt very stable...? If not I'll just stick to Hyperdroid .
Thank you!
I think <insert name of ROM here> is the best for battery life.
Allow the next 10 posters to fill in the gap with several different answers.
I have been able to get out around 36hrs from Gingermod v0.7. the key reason behind this was that i used to switch on data or wi-fi only when i was using it and not all the time.This drastically reduced my battery drain.For eg. i lost only 1% battery during the 8 hrs i was sleeping.
See this thread:

Pointless thread that will be closed down - there have been 15 of these threads in the last couple of weeks
You can find all this out by searching first.

Only you will find best rom as so many variables .....

I'm using Seraphim and I'm happy with the battery life. It seems to be worse than the GB ROM but I can get about 2% down every hour when the phone is idle.
I am thinking of trying different ROMs and battery life is very important to me. Which ROM will give the phone a better battery life based on your experience?
Thanks.

ah ok, im in search of a good ics battery friendly rom as well, actually downloading dag's ics "hybrid" rt now. i'll give it a go for the next couple days and post back. i was seeing about the same as you for seraphim.
In my experience, unless there's a bug, a ROM has little effect on battery life. Android is going to use a certain amount of power to run itself, and there is little that a dev can cook into a ROM to change this. Beyond the system, battery usage is from the screen, apps, and radios. If you are in an area with poor reception, and have lots of apps and widgets that frequently update in the background, this will decrease battery life.
I've used both DaGr8's Alpha II and Seraphim, and my battery drains less than 1% per hour when idling.
Guys a Search would have told you that Battery life is 99% on the user and has almost nothing to do with the rom. We could be running the exact same rom and get very different battery lifes due to the apps we use and how we have the device set up.

I want to try a rom+kernel combination that gives 10hrs+ battery life with smooth daily performance. There are many people posting threads about their awesome performance with 12hours of battery life. I don't want that much, but at least, a minimum. Of 9-10 would satisfy me. I have gone through many roms but, none of them have given me that much. I am not a heavy user.
Perhaps you might want to share with us which ROMs you have already tried, how each one performed, and how exactly you use your phone?
buddy u got beast. battery backup is same on all Custom Rom except Stock u, you can try Faust, velvet or Valcun which are different in there own way.
remove unnecessary apps and install Greenify.
dude, we get 10+ hours of SoT because we're using the phone all day long...
if you use it for 2-3 days you will just get 7+ hours because the 3+ hours will be consumed when you're idle....
