Im using cm7 right now and I really don't like it in terms of battery life. What are u guys using?
the rom won't give you bad or good battery life, the kernels do. try the eclipse or kangbang kernel. also as you know keeping 4g on no matter what rom causes excess drain.
that's funny. CM7 is one of the best for battery life. have you tried out different radios? the MR2.5 worked well for me when i was on CM7. i've been switching around lately between a few of DroidTh30ry's AOSP ROMs and using the new MR3.5 radio. it's still been doing well.
in general though, i find that AOSP roms are much better on battery then Sense based ones.
[EDIT] yeah the kernal plays a big part to. i decided to switch back to CM 7 1.6.1, MR3.5(802) radio and using Tiamat's kernal.
the Imoseyon 'leankernal' does a really good job to

I'm getting excellent battery life from SkyRaider Zeus Preview on his stock kernel and the rooted 7/8 OTA radios.
Best ROM i've seen, period.
battery life is an awfully subjective topic, right up there with "best rom," "best kernel" and "best phone"
Don't forget "coolest car," "HOTTEST PORN,"AND "BEST WINE."

Amen, I totally agree with you!!
theres a lot you can do besides rom for battery life, but contrary to what is said above the rom DOES affect battery life. im on synergy and its great. but i also undervolt to 246 when screen off and run dconfig to kill apps when i get to 200mb of ram left. what ive found most affects battery life to be honest is how good your service is where your using your phone
Try this kernel

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.
In the end there is not best rom. Only what works best for you.

Not sure if it's me but figured I'd ask the community. Has anyone been getting worse battery life after flashing ICS? I came from UnNamed rom with Entropys daily driver and had about 40% after 17 hours on a daily basis (2 and a half hours screen time texting, web, XDA, etc)
Switched first to shostock 2, and ended up knocking down to 50% under 8 hours with the same amount of usage, flashed on over to phonebricker with siyah and same thing. Anyone else having similar drainage?

Someone reported having superior battery life with ICS on Shostock, Bricker or AOKP.
I, in the other hand, never have a great life on it. Considering light usage, getting 20 hrs max (where I used to get close to 48 hrs) including roughly 2 hrs screen on and 2 hrs talk time. Not great at all, but not bad, I can survive.

Exactly! I know others who all have these amazing battery stats yet for some reason I just don't. Couldn't figure it out for the life of me when I haven't been doing anything different. Was beginning to think maybe I'm just enjoying ICS a little too much and need to put the phone down..

I was getting 30+ hours a charge easily on GB if I sidestepped a few battery killers. I get nowhere near that on any of the ICS roms but it's worth every juice sucking second. I love it.

So an i777 running Gingerbread has an LDC screen and an i777 running ICS has an OLED screen?

I use phone bricker 2.7 as a daily driver and the battery life is pretty decent. The MIUI port seems to do even better (I uninstalled it because somehow it was unpredictably laggy). Might as well try those too.
I started running AOKP about a week ago and my battery life improved quite a bit over the rooted stock rom. But I never have had very good battery life out of the stock rom anyways, except for maybe day or two after a factory reset, I would have OK run times until that dreaded wakelock kept sneaking back in the picture. AOKP has been much more consistent for me and I have easily been lasting 16-18 hrs with light/medium use and atleast 40% remaining. I'm running Siyah kernel. I haven't tried any other roms.
I think I'm gonna be going back to gingerbread for about a solid week to see if it really is ICS. Used to get amazing life on GB, then switched to ICS and my battery went to hell.so I got an extended battery and all that did was basically give me close to what I got on gingerbread, so the inconsistencies are starting to bother me a bit. Maybe I'll return to ics sometime in the future to see if anything changes. It's been fun though, and there's a lot of things that I'm going to miss....Oh well

ICS VS GB
I thought Gingerbread had much better battery life so i switched to shostock 1. However, the battery life there was about the same as shostock 2. My recommendation is to severely underclock it (200 mhz) when the screen is locked. i can go for hours and only use 1 or 2 percent and the battery will be left for you when the screen is on which is when you need it. AOKP + Fluxi= awesome
Okay so I've been messing around with roms lately and I'm somewhat a flashaholic lol
But now I'm really looking for something flexible but GOOD on battery life.
What Combo is best for battery life?
such as Modem & Kernal (+ Rom)
I'm currently on this (at the moment):
Rom: MIUI V4 (360 PRODUCTIONS)
Kernel: 3.1.10-subZero-1.6 End_of_Line)) #167
Baseband Version: T959UVKA7
My battery life isn't really too special, I have wifi on, 3G preferred, auto brightness, sound on high. . .
85% - Discharging 2h 5m 30s on Battery
Any ideas on bettery battery life or is this pretty much good/normal?
also my battery isn't a samsung battery its an MYBAT 3.7V LI-ION Battery VLN-08 1200mAH . not too sure if that plays a big role in this.

I'm going to make an assumption here, and perhaps it is an incorrect one.
I've installed countless ROM's on my Vibrant, and I've had mine a VERY long time (got mine the week before the official launch...long story).
I've found no roms that match the overall battery life of Samsung 2.2 froyo based roms. It is for this reason that, though I've tinkered with practically every single gingerbread, ics, and jb rom ever released, I always go back to my personal favorite as a daily driver. Project V w/Bali 1.8.8 kernel and KB5 baseband.
My assumption is that the "black box" effect is at play. Getting the last baseband available to us (KB5) to happily play with later builds of android has always been an exercise in frustration. Sure it has been made to "work" with later builds, but given the closed nature of it it's clear it just doesn't work as seamlessly well with anything else.
My battery life with 2.2 based roms has always been way better than later android builds, often lasting twice or more as long.
Thanks for the link I'll take a look at it.
@masterotaku : Everyone says Froyo has the worst battery life ever :\ but I also believe what works for my phone may not work for yours, and I do know Froyo is a very stable rom it was the rom i ended up going back to and sticking with on my MyTouch .

Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
