ROM & Kernel with the best battery life?

Hi, so far the only rom I have used is CM6, and the battery life is just absolutely terrible. Maybe its just my nexus, maybe not, point is I want a new ROM.
A ROM that you guys have tried and decided to stick to.
Battery life is VERY important to me.

Try IntersectRaven's CFS kernel, best I have found for CM
For ROM try Enomther, battery life pretty good on that one

I had been using CM 6 for a while and just recently switched over to Enomether's latest TheOfficial ROM. The battery life is now DRAMATICALLY better. Just looking over the Juice Plotter graphs shows that the standby time overnight is almost flat. Say 3-4% drop every 3 hours or so. With CM6, the battery level is on a constant and steeper decline, even when not in use. I didn't take any records, but my N1 on CM6 would be down to ~45-50% overnight if I forget to plug in the charger (from full). I heard that SetCpu will help, but I don't think it worked out for me.
Enomether has its own CPU Governor and while it doesn't offer as many features as SetCPU - the ROM's default settings work well right out of the box - no tweaking is needed really for the CPU governor.

I too was having really poor battery life with CM6, losing about 50% within 8 hours after charge, without even using the phone much! I'm trying out other roms right now just for fun. I'm using Evil's Nxsense but with the kernal posted by Autinhyeu (post # 8541 in that thread). So far seems to be holding battery extremely well. About 5 hours since charge and about 90% battery.

LeoFroYo Rom is pretty good with battery

try the leofroyo rom latest beta. i get great battery in standby with the stock kernal that it comes with. 2.5 hrs per 1% battery. typically in a day making calls and using the internet, i lose about 30%-25% battery. not too bad.

cm sucks when it comes to battery life in my experience. i tried the 6.0 version when it came out (first stable release) and battery life was horrible.
5 hours since charge? only standby or some usage?

That was mostly standby with setcpu profile setting cpu to minimum when the screen was off. But even with those same settings on CM6 my battery would be about 70% after the same amount of time.
I just reflashed cm6 but with that other kernal so I'll see how well it works today.

MIUI has the best battery life of any ROM I've used on my N1.. idle drain of about .5% / hour when using pershoot's kernels from droidbasement.

I'm using shadow rom2.1 stripped down and I get about 16 to 18 hours usage.

I'm using CM6 and my battery life is great. I got rid of my Seidio extended battery to get an Otterbox case and the stock battery on CM6 is awesome.
My phone has been off the charger since before 1pm and now at midnight its on 46% and thats with heavy use of Angry Birds, text, emails and web browsing !

My battery life is also acceptable on cm6. Not amazing but acceptable. Then again I put mine in airplane mode overnight and get about a 4% drain, which I kind assume might be something to do with my Widgets.

Okay, so I decided to try one of these two ROMs:
Enomther
LeoFroYo
not sure which one yet, and not sure what kernel to use with the ROM I choose.
I hate switching ROMs cuz of the wiping and restoring and all that crap.

Rodrigo's miui is the best I've seen.
Easily lasts the whole day

do you guys know if the leofroyo rom will work with slcd nexus w/ updated HBOOT??
i posted in the leofroyo rom thread, but no replies yet. itching to give it a shot.
cm6 is eating battery like crazy!

rods miui has amazing battery life It lasted two days for me on release 1.3 I think he is on 1.5 now

dont see why not! give one of the betas ago!

What ROM offers the best battery life.

I am running Syndicate/Froyo right now and the battery life only seems slightly better than stock did.
I did calibrate the battery too.
I keep reading about these poeple with 30 hours of battery life.........what are you guys using.
I am thinking of trying out EE but this ODIN stuff looks confusing

I recommend Nebula Rom. Super fast, stable, and I usually get about 12-18 hours depending on what I do.

That what get now

The 30+ hours are on custom 2.1 rom/kernels.....since 2.2 was a leak there is no source code for the devs to tweak to get insane battery life. But, for me, froyo has given me about 20-30% better battery life vs stock 2.1 and since custom 2.1 roms pretty much doubled my battery life so if they can do the same for froyo it will beawesome

[Q] best rom and kernal for battery life

i am sure there is a thread on here already for this but i can't seem to find it i am looking for the best kernal and rom combo with the ultimate battery life with also o.c. supportive as well i am wondering what is it that i can do or flash i am currently running g.b. stock rom with a cynobenmod kernal i am wondering what everyone else best experience is also batteries ext. does anyone have a great cheap battery that extended there life on the evo i use tethering about 5 hours a day and i really need that to work to last all day and making 6-7 phone calls thorugh out that day just so you know i am using a evo 4g

if you don't mind AOSP-based ROMs, try Deck's ROM ([6-21-11][ROM] gingerbread-evo-deck [1.2][2.3.4 Stable] - xda-developers) and then flash a Tiamat kernel (I've been using the latest and its been great) ([Kernel][AOSP] Tiamat | 2.6.38.8 | 6/6/11 -xda-developers). You can also try viperboy's undervolt mod [MOD]viperMOD for AOSP Kernels - v3 beta RC2.4 |Updated 6.14.11|*App in Progress!* - xda-developers on top of the kernel...helps out with battery life. Try the -100mv first then step down gradually till your phone is stable again

I agree with cg about decks and viperboys script. I personally get better battery life and performance with savagedzen. Also try underclocking down to 691....I do and notice no slowdown.

I have been using MikG v2.15 and battery life has never been better. Also it is far more stable than the custom kernels with voltage tweakers in my experience.

+1 to what Ronnie said. I like leaving as much stock as possible. I am running MikG 2.2 and never have to worry about a charger.

I've used MikG, Synergy, KingsROM, etc. (essentially all of the GB Sense-based ROMs that were 2.1/3.0 hybrids). And yea MikG had the best battery life compared to the others but I would only get maybe 12 hours out of it. What are your settings??

I'm with the Deck's crowd here. I use Deck's with Tiamat 3.3.7 (too lazy to try the newer versions), and I don't usually hit 50% battery life till about 18-ish hours off charger with constant texting/Tweetdeck/push notifications and a few phone calls.

I am not using any special settings or tweaks. Using Google sync to access 4 email accounts, etc. Also I unchecked the Always On Mobile Data setting.
It has been 100% stable - no stalls, connectivity issues, or anything like that.
Nice thing about MikG is that it uses Sense.

Decks and the latest tiamat sbc w viper boy....2600 mah battery I'll get 40hrs

Try MIUI's newest release...not sure what it is off the top of my head. Definitely the best battery life I've ever gotten. Get a solid 15 -16 hours with medium to heavy usage. (fbook,youtube, calls, texting, web browsing, downloading).

Im with you - Im on MikG now I love the ROM but I do not even get 12 hours with a 3500 mah battery. That is on a heavy usage day on low usage days I get 18 houirs. Not horrible but not good. Was actually looking for a sense based ROM with better battery.

Cyanogenmod 7 with tiamat kernel, stable version gives me great performance and stability and GREAT battery life.

Check my sig for my setup, I am currently using my AOSP setup. I get at least a day with heavy usage, stock battery. I use Juice Defender too, it seems to work well, especially with AOSP ROMs.
Radios matter too, if you have high Android System usage or cell standby, flash some new radios.

The same here, just swtched to Bali 1.2 1.2GHz two weeks ago. Overclocked but undervolted using 3500mah battery. It lasts for 36h light, and 14h heavy usage..

Just about any of the major Froyo ROMs with a UV kernel (Bali, Overstock or Trigger UV versions) will give great battery life. Even the 2.2.1 versions (though I'm not sure what advantage that .1 gives)..
However, don't believe anyone when they say you can get "great" battery life on CM7 or ported GB Roms. It just ain't so. Yes, there have been improvements on those Roms, but you'll still get half the life of a Froyo ROM or worse no matter what you do. Stick with Froyo if battery matters at all to you.

thank you. i'll check those roms you guys recommended.
now i'm on biffmod 1.3
i like the look of it.

Be careful who are you calling **** kido!!! I've tried most of the roms, kernels and modems out there and telling me that you have over 50% left after more than 24h usage with 3-4h internet browsing and 1h gps navigation sounds like a joke. I've been playing with my Vibrant a year and I know how much you can really get from the device.

Currently on Nextgen V2 with Immortality. Currently giving me 5 hrs GPS active, screen on with wifi on.
I've been able to replicate such life with other TW ROMS like 1.3.2_test and TARD with Bali 1.8.8 UV.
I haven't had much the same success with the Dragonmodz and Overstock UV kernels.
The Bali and Immortality kernels are the ones for me for now.

interesting discussion. apart from the samll fight.
i'll check this out and hope to get to a rom with good battery life.

If you try Immortality 2.2 Kernel, use setCPU to undervolt. My set up is below (just a Reference since every CPU has different capability).
Stock KB5 with Immortality 2.2 Kernel
Max Freq: 800Mhz
Cpu Governor: Conservative
800Mhz || -100mV
400Mhz || -125mV
200Mhz || -150mV
100Mhz || -350mV
Phone runs smoothly and no Sleep of Death. The Back Cover stays COOL when doing web browsing, youtube, or playing game (Avatar SD Version does make the back cover warm up a little bit, just a little bit). No more burning up while charging. Battery life is Phenomenon.

Which is the best battery-friendly ROM? 20.09.2011

Guys, i really like the swiftdroid ROMs but they are all battery drainers.And i cant be at home all day or at work and charge my GT540 all day. Seriously it isnt alive more than 1 day.So want to learn which rom is the best battery saving.

try 2.1 Rom ,they have a good battery life

It all depends on the conditions. Swiftdroid does use more battery life. Try to go for something lite.

2.3 is power hungry and very fast, 2.1 has very good battery life but not so fast
so..... 2.2!!!!!! stable fast good battery life!
i recommend project utopia

Get Utopia. You'll get the speed of 2.3 and battery of 2.1!
