What's the best battery rom and kernel that doesnt sacrifice performance ? Thanks!
I'm currently trying DU, but I'm not a huge fan of it. I would recommend Pure Nexus ROM as the best ROM, and I'm going to go back to is as soon as I can.
For kernels, I've used ElementalX, Jolla, and Phasma, and they're all about the same. It more depends on what CPU Governor/Profile you use that will get your the best battery life.
I found out Tesla rom + EX as the best battery friendly combo, try it
Questions like that are not allowed on XDA because all devs are hard working on our devices and saying this is better than this is not friendly for devs !
And there's no rom based on battery ... Only franco kernel is based on battery.
I'm also current using Pure Nexus, ElementalX Kernel with Hawktail 1.2 as my CPU Gov. Though i'm currently testing it out, i got a full 5 hours SOT, this includes watching vids from Youtube, playing games (30 mins) and mostly browsing in Facebook. I didn't also let my phone to go idle on screen off as i'm testing out how many hours i can get without turning off the screen. My brightness level is 25% without ambient settings. I'll post a complete review tomorrow as i'm testing now the ROM with my usual daily tasks. But so far, the ROM is so great and i can't feel any overheat, which happens to me from the stock ROM.

Hey all, I was wondering if anybody had any suggestions for a kernel that is good for battery life. I am running the stable release of CM7 and I have the OEM extended battery (came with the phone when I bought it) and I currently can get about 1.5 days of moderate use (wifi turned on whenever available, frequent twitter/facebook/foursquare updates, heavy texting/emailing and moderate web browsing) but I am always open to new options for improved battery life.
The kernel I have now is underclocked by about half and I find that helps a lot (if I remember correctly, it is the stock kernel).
Best kernel in my opinion for AOSP is Tiamat: http://tiamat-aosp.com
I am somewhat new to the non-stock rom/kernel game but have the latest version of incredikernel with CM7 stable and really like the combo so far
The stock CM7 kernel had lower wifi performance for me with Incredikernel it is back where it should be

Agreed. Incredikernel FTW.
Flash the lower voltages to get even better battery life. If your phone can take them without rebooting often then you'll get a significant increase in battery life while maintaining the same CPU power.
2.6.37.6-incredikernel is working phenomenally for me
Incredikernel is the best I've found on any aosp rom. Awesome battery life.

Curious, is there a guide or instructions on how to flash the lower voltages. I've checked out Chad's thread and it confuses me.
Incredikernel FTW
I went with Incredikernel. So far so good, it's been off the charger for about 13-14 hours now and it's at 82% battery. Wifi and GPS both turned on with a decent amount of texting/email checking and a little web browsing. It is underclocked about half way with SetCPU and still very snappy and responsive. Definitely happier with my phone than ever before.
Incredikernel is what my friend uses and he loves it.
Also wanted to add I have heard good things about Tiamat as well, another one you couldnt go wrong with.
Been playing with many combinations of ROM and kernel yet seems no matter what I try battery life is poor. Right now running coreDroid 1.3.3 with latest Franco kernel seems so so with slight under voltage settings within setcpu. So what is everyone else opinions? Thanks for feedback!

My best combination has come from AOKP Milestone 3 and Faux's 12u kernel. Usually get 16-20 hours with light/mod usage during the day and heavy usage in the evenings.

Best battery life I've seen yet is the stock 4.0.4 release w/ the kernel that comes with it. I get 4-7 hours with mod-heavy usage and 14-16 hours of light-mod usage.
I get 2-3 hours using Franco's kernel. Really not great. I should look around for a better kernel to suit my usage.

Jeez you use your phone a lot. I'm on kang 1/31 with faux's kernel. I use my phone for the commute to work and turn off lte when I get there. Mostly music and reading. I have it underclocked at 1060mhz and running under performance governor, it helps me check my phone and send out texts at work faster. Then at night I flip on lte again and a lot of the times go out. I don't think 15 hrs is too bad.

best battery life i had was 36 hours with moderate usage. no lie.
aokp b17 + francos 13.1, smooth and amaziiiiiing battery life. if i wasn't a flash junkie, i would be sitting on that right now.
I'm a little confused by your post. Are you developing a kernel or a rom? Either way looking forward to the release.

I mean screen on time!
I got 42 hours without charging the phone yesterday, with 2 hours 40 minutes screen on time. I was using it very sparingly over the period though.
If we you want this thread to be useful we need to make sure all posts at least state screen ON time. Even then there are so many other factors:
Screen On Time
Total Up Time
GSM/LTE
ROM
Kernel
Kernel Freq
Kernel Governor
Screen Brightness (Avg)
WIFI state
BT State
etc
Okay so I'll start...
Screen On Time - 3-4hrs
Total Up Time - 14 to 25hrs
GSM/LTE - GSM
ROM - AOKP 22
Kernel - Franco 16.2
Kernel Freq - 700/1000
Kernel Governor - Turtle
Screen Brightness (Avg) - <40%
WIFI state - On
BT State - Off
Clarify Battery Life Info
I am not developing anything. I am just wondering what people that flash different kernels and roms have experienced and settled on as far as best battery life. In my sig there is the one I currently use. I actually have been trying franco kernel lately and that seems to be slightly better. Its tough to tell since I try to plug in the phone as often as possible either to outlet or my laptop. Does that help clarify what I am curious about??
hey guys, i am looking for a kernel that will save me on battery. i am running zombie 4 rom. it says it runs the dark x kernel. i don't need to be running at super speeds but i don't want screen freezes either. i just want to be able to play my satellite radio without the phone draining 3 percent every 5 min or so. any help would be great.

I would be interested in this as well. Currently I am Rooted and have tried a few ROM's but haven't found one yet that doesn't have some bug or another. {Granted, I haven't tried them all} Tried one ROM that really distorted my custom made Wallpapers, which is a big deal to me. So... yes, any info on a better battery life Kernel would be welcome.
Currently I am not a "heavy user" on the phone. Talk - Text - You Tube occasionally... that's it. Constantly looking for better ways to improve this already amazing phone.
Eugenes kernel has given me great battery life. Either get down with Eugene's Macnut ROM which already has it or search for it under the general section under the bounty thread for Eugene. Its in page....58?
Keep in mind that the "beta" kernel does not have bln support but works just fine so long as you use the lionheart governor.
If you can't find the bounty thread then I'm sorry for you.
Synergy kernel has been awesome on battery for many.

I second just using macnut rom. I've tried em all, and his always gets the best battery life (for me).
I also undervolt via system tuner pro so that I'm at 1137 at 1.51

How you use your phone determines the best way to get the best battery life. Basically there are two ways to save battery: cutting power when not in use and delivering less power to the processors.
If you use your phone intermittently throughout the day for texts or calls, you'll get the best battery results from kernels/ROMs/apps that cut unnecessary functions when you're not using the phone. For example, juice defender cuts your wifi and mobile data when your screen is off and reactivates it every 15min (can be configured otherwise) to check for notifications. Darkside's Digital Warfare utilizes something called "deep sleep" which actually completely turns off your processors when the screen is off, but keeps the basic cell radio on so if you receive a text/phone call it will wake up the processor. These functions have the largest and safest impact on battery life.
If you're constantly using your phone and you want better battery life, you basically only have one option: undervolting. This is essentially supplying less power to your processors, which can be done through system tuner. It's not a free ticket, however; if you undervolt too low then at higher frequencies (playing games, etc.) your processor will become unstable and your phone will randomly reboot. If you encounter this, then don't undervolt that much and up the voltage to the last safe level. Just for reference, undervolting by 50mV is usually considered safe and undervolting past 100mV usually results in boot loops. But how far you can actually undervolt depends on your individual phone hardware, there's no universal answer. Make sure to not set your undervolt settings to set at boot until you find a stable voltage. Otherwise, you'll be forced to restore a nandroid if you encounter a bootloop.
TL;DR
If your phone already lasts a day and you want it to last 2-3 days, look into ROMs/kernels/apps that cut unnecessary functions when not in use. Most effective way to extend battery.
If your phone lasts 8 hours and you want it to last a day because you're a heavy user, look into undervolting with system tuner.

stock rom. Just download a battery manager from the Market.
What's your favorite kernel, considering battery life, speed, OC/UV options, and stability? I've been alternating between leankernel and franco.kernel and can't decide which I prefer. If you choose other, specify what your favorite is!
Trinity and lean are my favourites
Trinity... lean was also good for me...

I am using the kernel that come with CM9 beard off of Linux and I love it, I am getting better battery life using this than Franco's, but I'm not sure if you can just the kernel, I think you need to be on the ROM as well...

i've tried lean,franco,glados and trinity..
both lean and trinity are my favorite, but for now i think i'll stick with lean
trinity for smoothness and super fast kernel
lean is for fast kernel + good batt
the latest trinity kernels...ofv and flatline are equal and in some cases better batt life then lean...without sacrificing performance...
I just recently purchased a Galaxy Nexus and have only tried out Franco Kernel. I get an average of 3.5 hours screen time while underclocked. After I record some accurate results, I think I'll switch to Lean Kernel in order to see which Kernel gives me the best battery life.

My thoughts exactly, although I've had my GNex for over 2 months.
Why not try both yourself for a while? Just flash them and see what suits you best... For me I started with Franco and just sticked to it as it works perfectly for my needs but I can't compare the both.
Tried Franco kernel, 17.2 give me the best battery life with slightly more than 3.5 hrs on screen time, for M1 and M2, can only last slightly less than 3 hrs on screen. Anyone also experience this?
Anyone here tried GlaDos kernel and have any reviews?
GLaDOS review
GLaDOS has both speed and good battery life. It's more or less based off the theory that processing stuff at higher speed will allow your phone to get more quickly back to sleep (not the same as "Deep Sleep"; the C4 rest state happens concurrently, even when you're on 1200 mhz).
But the only way to see if this pans out is to use it. You should try it with your daily usage and see if it works for you.*
For example, I find it has the best battery life for playing music with screen off (3% per hour speakerphone, 5-6% on bluetooth) and matches [or beats] the others for stress-usage (screen on, 8-10 apps in background gets around 20%). I haven't tried intermediate usage, because frankly, I don't use only a few apps when I'm using, so that's a gap to fill I guess. Note: streaming music is apparently a problem, judging from recent reports.
*Use BetterBatteryStats or an app with series history; the graph should become linear partway and that's when you know to take numbers.
Yeah but how do you backup your default kernel?
I just installed Franco kernel, why would one install lean kernel? what's the difference between two anyway?
I think the answer to this question is, 'it depends'.
I think the ROM/Kernel combination has an impact on performance and battery life.
For example: previously while running bixie's stock and AndroidME, I had great performance with Trinity. However, on AOKP, trinity delivered poor battery life. With AOKP, I found Franco to be a better match.

OK, you're right I didn't really gave you enough information on my end)
I'm using stock Jelly Bean 4.1.1 OTA, I did rooted my phone so that I can install different kernel
I'm using few social (facebook,google+,foursquare,etc) apps, some messengers (what'sup,kik,google voice)
as far as data goes I'm using Juice Defender and that helps me a bit with my data on/off
but what _REALLY_ kills my battery is screen, in the best case scenario I was able to archive a little over 2h of screen time and in most cases it's ~1:30h
i'm using standard battery in my phone.
my goal is _SOMEHOW_ increase screen time
that's why I'm trying out franco kernel)

Hi
Im going to summer camp and I can be long time without power. So I need best rom, kernel, and maybe radio for my Desire hd. I need rom with camera. Plz tell me wich compilaton have best battery life.
My 1st post, sorry for my bad english
In before someone scolds you for not searching
Radio is subjective to area.
A rom with great battery life without changing anything could be either black ice or gb rd miui. Both are close in battery life, and from all the roms miui has the best cam in my opinion.
Unless you are willing to buy a cam from the market.
Your best option is to test a few roms out for a few days. Get additional batteries cause no rom will go beyond a day with heavy use. On standby you would get two days, maybe more.
Edit: however I've seen some screenshots here and there of people with crazy bat stats. A few, but there are a few.
You can also look into v6 supercharger, there may be something there for you.

I use Cyanogenmod 7.2.0-RC2 with LordModUE 8.9b7-CFS kernel, and it has a really great battery life.
My radio is 12.65.60.29U_26.14.04.28_M
I have set cpu governer to smartassv2, with min frequence to 122MHz and max to 1152MHz.
With these settings, the ROM runs smoothly without any lag, and I get about 24h of battery life if I use the phone normally: music (2h), call (1h), internet (?), GPS+Endomondo app (~1h30), Wifi (1h)
