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

Using CM7? You must read this.

Ok guys. I have to admit, I was about to give up on CM7 due to battery issues and what seemed to be memory leaks progressively making my phone lag more and more throughout the day. I have found something some of you may not be aware of and I wanted to share this amazingly helpful kernel with you.
Using x99, Scary, and stock kernels regardless of governor I seemed to maybe get 8 hours of battery life with moderate to heavy use. I am proud to say, using bcnice20's kernel I have had my phone on for 9 hours with 60% battery life today. This is incredible, even with lighter use on the other kernels I had NOWHERE near this amount of battery left.
Most of you may not have seen this kernel because it isn't posted. (as far as im aware) Let me help you out. First, go into your Market and download Kernel Manager. There is a lite version in there that is free. If you have an extra buck or two donate to the developer for making a neat app where you can download kernels in a convenient place by downloading the pro version.
What you will be downloading is called bcblend SIO tinyRCU kernel. I have not true VR tinyRCU kernel yet. Not sure what the differences are, if someone could elaborate that'd be appreciated.
Regardless, I find the sweet spot for this to be at 245MHz min and 1GHz max on Interactive governor to work really well. The phone does not seem to get laggier throughout the day and consistently performs well, snappy, and just way better than the other kernels. (No offense to x99 and Scary, I appreciate all you've done!)
Give it a try and let me know if you all have similar results! I have heard that AOSP gets less battery than Sense ROMs from people on this very forum, and this may be the kernel to put that little debate to rest.
Oh, and be sure you have the latest CM7. I am on 7.0.2.1 trying this out.

I have been using the x99 kernal and i have about 1 d and 12 hrs with about 45 % left.. I also have the calibrator apk from the market so it wipes the battery stat when im at 100%. and various other apps that deal with the speed of the sd card and what nots. So, me coming from the Hero is very happy with this phone...
Thank you for sharing your findings... THIS IS SO AWESOME !!!!!

That's amazing battery life. I can't seem to get that great of battery life on CM7 as compaired to stock sense roms. What calibration app are you talking about exactly? There are a few on the market.

[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.

Best Setup/Kernal for Battery Life

I'm wondering what others have experienced as being the best setup for battery life on the N1? I'm running Cyanogen 7.1 RC1 and haven't been that happy with the battery performance.

Latest CM nightly with juice defender ultimate nets me about 36 hrs normal use.

I've been using CM7.1 RC1 for a few weeks now... battery life did seem pretty weak but I then tried out JuiceDefender Ultimate. It actually made the battery life worse, which didn't make any sense... I gave the beta a try and it practically doubled the battery life right off the bat. I'm currently using the stock Aggressive settings for the beta so I'm assuming I could do better if I did custom settings.

ss4n1 with any kernel that works with it

Yeah, SSN1 is nice, but I have tried almost every kernel out there with a multitude of voltage settings and I have yet to see one that gets better battery life than the current CM7 one. I am not sure if the one they use for nightlies is different than the RC, but it is very very impressive for battery life. It doesn't have any fancy add ons or governers it is just low voltage and no frills.

Interesting when i use ss4n1 on top cm7 with slight uv and smartass or interx I yield way better batt

Interesting, last time I tried to run it over that kernel I didn't think it was working. No matter how far I undervolted it it kept running, usually if you push it that far it will freeze. I will try again when I get a chance. Were you using the scrip itself or ckz tools?

Am running CM 7.0.3 with Tiamat 4.06. Tiamat increased my battery life a little. I installed JuiceDefender and battery life by the end of today will be more than double what I saw on 7.0.3 w/o Tiamat. ++1 for JuiceDefender

I haven't tried SS4N1 yet. I'll be trying it with MIUI.

Try using the stock CM7 kernel with Juicedefender, I think you will see a significant gain again. Tiamat makes a nice kernel, but it is not known for good battery life.

Try using the stock CM7 kernel instead, I think you will be pleasantly surprised at the additional increase in battery life. Tiamat makes some really nice kernels, however they are not known for good battery life.

U have to use the script czk tools is just a gui

Not anymore, ckztool now includes an updated script as part of the program, check out the thread. He updated it about a month ago. It is nice cause you don't have to reinstall the script everytime you flash a new rom or an update. It installs the script each time you open and activate the program.

Get an extra battery from ebay for $5 (and charger $8) and keep that with you.
Beats any software tweak

If you don't mind carrying a battery around;-)

Just installed latest version of SuperOSR, new kernel combined with Incredicontrol to undervolt is producing pretty amazing results. It is a very cool Rom on top of it too.

Battery Life on different ROMs

So after toying around with a large number of the ROMs on the Aria, I've found a couple things:
The gingerbread ROMs, including CM7, always suck my phone dry the fastest. I'm trying to get ~2 days out of it, but it just doesn't happen. With setCPU and some different profiles, along with minimal usage (~30 minutes talk time/day, maybe 30 minutes on the internet, and pretty much everything off, and maybe an hour of music) I get down to 30% or lower by the end of the day.
The GingerSense ROMs are the worst; I rarely make it through a full day with the same stats described above.
However, I've been running Liberated Aria (a FroYo ROM) for the last week and I've found it to be spectacular in terms of battery life. I'd go to bed and set the phone down with 60% battery; wake up and it's at 55%. Gingerbread would never let me go through a night without taking at least 10% of the battery.
So that's what I've found. What are your thoughts?

I haven't used any of the CM* ROMs but I have used the liberated brand ROMs. As you have found out, if you want a sense based ROM, GenePoole's Liberated 2.2.2 is the way to go. With out a doubt it is the most polished ROM with spectacular battery life. If you use it in conjunction with the Set CPU program to dynamically underclock and overclock your phone, you can't go wrong. You will get ~2 days of battery life.
I'm not sure why it isn't included in the ROM list in the pinned guide... It's the evolution of liberated 2.2, which, should be depreciated in all honesty. There is no reason to use liberated 2.2 instead of 2.2.2.

Well, 2.2 does have a much cleaner look to the status bar, and is more customized than 2.2.2 is. Also, I've run into less problems on 2.2 than I have on 2.2.2, and although it's not a big deal, it's the small things that I've seen that make me happy about 2.2 versus the later variant.

I must have misread your original post. I thought you were using 2.2.2 instead of 2.2.
Anyway, based on my own personal testing, 2.2.2 has better battery life than 2.2, so that's why I used it. But, I never really ran into any real problems on either ROM.
This place has sure got quiet in the last couple of months...

I found CM 7.2 stable to be pretty good with battery life. With moderate usage, I would get about a day and a half out of it. This was much better than earlier versions of CM7 and all CM6 ROMs. I have had the same experience with GingerSense. Never used Liberated or FR008 ROMs.

I am waffling between the two, but 2.2 has seemed nicer to me, especially the deodexed version; is there a deodexed 2.2.2?

Not sure if there is or not, I haven't really been following the dev progress since I broke my phone in January.

I think it's just an Android issue coupled with ancient battery technology. Battery life between ROMs has been abymsal, regardless of tweaks. Personally, I am a CM fan, so I've been using it almost exclusively since version 6. Liberated Aria is a great ROM for those who like Sense, but it doesn't do anything CM cannot (excluding the obvious). FWIW, I have found that the typical "tweaks" (brightness, syncing, vibrate, etc) help here and there, as well as underclocking your kernel. V6 SuperCharger also provided good results, but I recommend that regardless of your ROM.
