So just got my Galaxy Nexus on Verizon and already unlocked running stock 4.0.4 rooted. I got the extended battery (2100) and I am still kind of disappointed in battery life. I mean, even on 3G all day yesterday it lasted maybe 9 hrs. I have turned off a lot of background apps but still hasn't helped much.
Any suggestions on good rom's/kernels for the best battery life without having to sacrifice too much on the performance side?
Figure it out man.
Everyone (literally) is going to say something different here.
I'll vote Immoseon's 2.3.0 stable with stock clocks but dropped the vsels down by 100 personally.
Next guy will vote franco's.
Next guy will say popcorn.
^This man speaks the truth.
The problem with statements like "X kernal is best for all situations" is that it CANNOT be true. Kernal's will give you varying battery life depending on what you use them for. Since only you know what you do with your phone, you'll have to do some trial and error to figure out which one works best for you.
I, for example, browse fb, read some ebooks, and browse the internet randomly, I've found Franco's Kernal works best for me.
Perhaps a heavy gamer may be that to be untrue. Perhaps someone who takes lots of video/photos do not agree. But for my purposes, I am satisfied.

If the next vote is for popcorn I'll feel like a wizard

Lol yeah, another one of the "best kernel for blah blah" collection...
Adding my agreement to try them out and see. I like imoysen, but that is based on my usage.
One thing I will recommend is fully charge your phone before installing a new kernel, then wipe your dalvick and battery stats after installing. Then let it drain till it dies and fully recharge it in one go. Then evaluate your battery performance. It will give you a more accurate view of how it will perform. giving your phone a few days to settle into a kernel always helps, imo.

Hi. Can you give us some definite figures and how much better battery life you're getting (percentage or hours). I'm a new gnex owner and although I will definitely root my gnex eventually, I'm currently reading through all the threads regarding battery life.
I'm a moderate user myself - using it mostly as an e-reader with the occassional gaming, browsing, call and text. Right now I'm getting the following performance:
15% remaining at 13 hrs
4 to 4.5 hours display time
Like most users, my main concern when I root will be battery life.
Wiping battery stats does not improve battery life.

Thanks! Just the figures I'm looking for.
Hello this is my first topic that I have posted up, I am aware that there is hundreds of these same type of topics posted up, and I apologize for another one lol.
Just wanted to get thoughts from other members on these results on battery life through AOKP b37(stock kernel that comes with aokp, without touching the CPU settings)
CDMA (with extended battery)
Settings profile:
Basically followed every guide on turning off certain settings to save battery (GPS,wifi use,rotation,vibrate and etc.)
Brightness: 4O Percent
Wifi: 80-90 percent on
Few phone calls
Decent amount of texts
I know that there is a lot Rom/kernel combos and every phone will give different results, but searching through other posts I have noticed that Franco kernel give fantastic performance and battery life to many users and give recommendations to other users to use it.
To me still kinda scratching my head and uncertain if these are decent, bad or good results, and having opinions will help me understand better
PS. Sorry for grammar
Via Galaxy Nexus [LTE]
That's just fine for a CDMA Nexus. It might even be a little better.

Hello,
My main criterion in deciding which of the many custom ROMs to go with is amount of battery life improvement I will have.
I see that the AHRD rom is the most popular, but does it also have the best battery life?
Or will the battery life improvements only occur when the source code is released and the One X runs on an ICS Kernel? I am under the impression that for some strange reason, the One X is running on a gingerbread kernel.
Thanks
This should properbly be in the Q&A section.
But anyway if you want great batterylife you should try Cyanogenmod. Those are the most basic ICS roms. Without any Sense gimmicks to suck the power.
That coupled with the Franco kernel should give you good battery life.
At the moment I'm using insertcoin with bricked kernel. And i have about 30% left at the end of the day. And I'm a fairly heavy user. So I find that to be acceptable.
And sorry if my spelling or grammer sucks, I'm from Denmark, so English is not my first language

Virtually everything that is asked on this board is a question. In fact, the majority of people who visit this board come to get a question answered. So the distinction is odd to me. People ask questions within threads that have declarative sentence titles all the time.
So if I had said "AHRD ROM gives insane battery life" then I guess it belongs in the general forum. Then if someone replies that Chameleon does even better as post #2, and I reply, why is it so much better as post #3. Then I have asked a question. My point is that in every thread there are questions, whether it's post #1 or post #3 seems like an arbitrary distinction. The fact that the Q&A section is not growing very quickly suggests confusion, since I still believe that if you analyzed the content of each post, and dare I say the overarching purpose of the board, is to ask questions. Newbies also see that he Q&A section isn't nearly as well frequented, so they post in the general section.
I think that the Q&A forum and the FAQ overlap in purpose. Anyway, just my 2 cents.
Thank you though for the answers to my question. I had expected, given the Anandtech review, that the One X would have comparable battery life to the iphone 4. However, I am finding this to be anything but the case, and I recently installed AHRD (wiped battery stats, etc). When trying to run down the battery (max brightness at 550 nits and surfing over 3g), I'm dead in 2 hours. My 2 yr-old iphone 4,with a peak brightness of about 500 nits, lasts approximately twice as long under identical conditions. I am finding the One X no better than the HTC Amaze, which has notoriously poor battery life. On the positive side, the One X's battery life is not as bad as the original EVO 4G, and the One X's standby battery drain is extremely low. I shudder to think what the battery life would be like if I had a US version which has LTE.
I have not noticed any improvements with any custom ROM thus far, but it's possible that using the screen at 75% brightness is basically such a determining factor that any gains in battery life are imperceptible to me. If someone can confirm that it is possible to drain the battery if you surfed at max brightness for 3 hours continuously and that that's just the state of phones today, then I can accept that. I just want to make sure that my phone is behaving normally and that any battery tweaks, cpu undervolting, wont' make a huge difference.

None of the custom ROMs change anything to do with battery consumption. A custom kernel could help, however I have tried them all and none of them make any appreciable difference.
Browsing over 3G seems to kill battery fast, I have never been able to get more than 3 hours screen time, and most of the time it is 2 or 2 and a half hours.
Hi thanks alot for the reply. I was thought that custom ROMs were supposed to improve battery life (one of the major reasons, if not the major reason, to install a custom ROM). In fact, in most of the intros for ROMs, they say something like "excellent battery life".
But you're saying that it is at the kernel level where improvements in battery life are made?
I agree with your conclusions--each custom ROM is about the same regarding battery life, and it is possible to surf and kill the phone in 3 hours of screen time, if I want my max brightness glory and over 3g.
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

99% of the time it'll be the kernel that changes your battery life (exception being if you're running a poorly written ROM, which is unlikely). Kernels give you the ability to tweak your phone for better performance or better battery or any combination of the two, whereas ROMs more or less just change the user interface. I have gotten pretty good battery life on Tiny's kernel, so you could try that, but you could ask 20 people, and you'll get 20 different answers for the best kernel haha
Yep its said kernel affects battery. My experience over a multitude of android devices says neither have a noticeable effect on battery life. I flash kernels for other reasons, not battery life. I've always gotten similar battery life on stock setup vs any combination of ROM/kernel. Maybe SLIGHTLY less battery if the kernel was geared for performance, but never have I seen a noticeable increase in life.

Biggest battery draw is going to be the one you didn't mention. Apps. Specifically the ones that run in background syncing data all the time. Try a little experiment by going to your mobile data usage, setting a limit and then disabling background data and auto sync. You'd be surprised how much battery Google now sucks down

i was using AK kernel and my battery was dying in a matter of hours. Ive been using Trinity and I've had great battery life.

I run AOSP Rom, SuperNexus, and my battery life is fine. It all depends on how you use your phone, what apps you have, signal strength.
No two phones are alike.
Imo, TW has better battery life. Less bugs, official support =better battery life.

Battery life depends on the user in the end, I've gotten over 24 hours on both. Greenify and DS Battery Saver will help a lot.
I've always had better battery life on TW than I have AOSP.
I run only aosp roms and get 15 to 18hrs especially after lightening zap kernel I have ds battery saver set to aggressive and Greenify (thanks bilgerryan, hadn't heard of it till I saw you post about it a few weeks back), last few days I have had over 3.5hrs screen on, granted I run my screen as dim as it will go. On stock battery

Overall, tw roms have been better for me in regards to battery life. That being said, given the time to let things settle and tweak they both can be great. If you want some suggestions a to what has been the best for me, drop me a pm and I'll name names. I don't want to turn this thread into a fanboy fiasco.

I have to say there is no correct answer. I never got more than 22 hours on a stock rom. One of the AOSP ROMs I flashed netted me 30+ hours. The next flash topped at 9 hours.
I think the battery life on stock ROMs is more consistent. With AOSP you get whatever you get.
Some AOSP roms are really good about battery life. I seriously have two that I like and one gets me about 8-9 hours while the other 14-16 for the same usage. It really, really depends on a lot of factors and I can say for sure, the rom is one of them.
