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.

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.

Best rom for battery life?

Does anyone know the best fully functioning rom with the best battery life?
(Sense or AOSP)
Thanks in advance!

CyanogenMod 7 with tiamat kernel gets pretty good battery life. The kernels tend to have mor eaffect on battery life then the roms themselves.

Thanks!
And for some reason my gf's EVO is dying really fast. I mean it drains 1% every 5 mins.
I replaced the battery and still the same thing. It's running CM7.

Try MIUI with Tiamat 3.3.7 SBC

Sounds like she might have 4g running all the time. Or maybe she might be updating/refreshing her background data to often. Only use 4g to down load big files or steaming vedio. Check her 4g connection and turn off or her sync rate set it to every 3 hours or more. If one or both are the culprit then she'll see a big improvement.
I run EVO Deck rom with cyanogenmod love it. And every thing works.
Hope this helps

I figured I'd chime in because you said you wanted a fully functioning ROM. CM7 and Deck had always yielded the best battery life for me with the last rev of the Savage Zen Kernel, but if you're like me and are very anal about the phrase "fully functioning" then it should be noted that the AOSP ROMs don't have 720p video recording. If that doesn't bother you than CM7 or Deck all the way.
That said i'm running TommyTomato's Classic ROM with the Freedom Agressive kernel and I'm getting 25+ hours on a charge which puts it on par with any AOSP ROM/kernel combo I've run. Might be able to get a little better on AOSP, but I'd say that's pretty damn good and it's fully functioning as in EVERYTHING works 100%.

4G is never on, Background data is unchecked, Email is set to manual sync, brightness is dimmed, no wifi. I feel as if I've done every battery saving trick in the book.
But I realized yesterday that I had SetCPU at 700mhz to save battery. I uninstalled it and the battery life wasn't dropping so rapidly. I can't say that was the issue. I'll have to run a few more test.

I will definitely try that combo and see what happens. I always flash roms but never kernels, to scared haha.

I get better battery on drews ICS ROM Than any from I've run in a year. I use it as a daily, it isn't completely fully functioning though, as 4g doesn't work and video is iffy.
That said, after I updated to latest radio, my battery is dying much faster........did you do the radio update ?

If you're flashing ROMs, you're already flashing kernels. Don't fear the kernel flash. Tiamat Lee on CM7 or Deck's is where it's at.

I meant interchanging kernels with custom roms.

I'm on Tommys Classic Supermagic,running the Hard to kill battery calibration script from Zepplins thread and i'm getting the best battery life i've had on any other rom and i've used this script with about 10 different roms,from AOSP to Sense 3.0,wont run 3.5 because of bugs and no 4G,after a full charge with alot of phone calls,texts and surfing,i held a charge for 4 days,it was 67% on the second day and actually died on the forth AM.

I'd definitely do a comparison between screen-on and awake time.
If you don't know this, you can access it through Settings > About Phone > Battery Use/History/Etc. See if the bar graphs of screen-on match awake. If you see a long bar under awake, but not a matching one under screen-on, you probably have a process or app that is stuck and needs to be removed/re-installed or have it's data cleared.
Note: it's normal to have some awake time that doesn't match screen on as apps/processes still have to perform there activities even with the screen-off, however, it shouldn't be a ton.
The best app out there to study this IMO is betterbatterstats. Hope this helps! Cheers!

Battery drain fixed on my Vibrant!!!

After flashing numerous ICS ROMS lately, I always seemed to have one major complaint. No matter which on I tried my Battery wouldnt seem to last more than 8 hours or so. Well, so far it's gone down only 6% in the last 6 hours with moderate use. here's what I've done (on Doc's Master ICS v5 Final, icyGlitch v14 b5).
***if anyone already has this listed somewhere, I apologize. I tried to find a post telling what to change and i couldnt so this is what i came up with***
1. set min/max cpu to 400/1000
2. use glichassV2 scaling gov
3. ns tools: active scheduler set to fiops
And I must say, Doc's Master V5 has easily got to be the BEST all-round ROM I've tried BY FAR!!! Vibranturk has damn near perfected this stuff.

Don't know if this is going to help, but appreciate you posting it. I have decent life on AOKP Build 26 with icy Glitch v14b5 with CPU set to 100/1300, Glitchassv2, default scheduler, and the 1800mAh battery. But if this helps squeeze a little more out, then all the better. Right now I get about 12 hours with moderate usage.
Sent from my rough sketch of a Vibrant on a brick.

I'm running TeamHacksung's build 16 and the main thing I've done for battery life is to customize the screen brightness levels. I had battery drain issues on it the first time I flashed, but I think it was because something I had done. I odin'd back to stock and reflashed CM7 then the TH 16, everything has been really smooth. I'll have to try out the changes you mention here to see how it goes... I'd love to be able to get the same or better battery life and more performance.

well, i made it to 12 hours. but about a solid hour and a half of that was playing Need for Speed Hot Pursuit so i imagine w/o that i couldve got quite a bit more life out the charge.
I had to turn the deep idle off when it came time to charge or it wouldnt charge correctly. and, for some reason it keeps saying that its 100% charged after just a short time. after a reboot the real percentage shows up.

You guys are on GLITCH kernel im guessing to get Glitchass v2 governor?
I shall try this for Euphoria today.

Can't believe i'm saying this but it truly does work. Usually after school my battery would go to a crawl to about 20% today it stayed up about 50% REALLY fantastic standby life.
Thanks OP

x66, if you want to get even better battery life, go into the display settings, in the Backlight settings, and you should be able to edit the 'Other Levels'... Bring those down a bit if you haven't already and you'll get even better battery life as you won't be using as much juice on your screen. Has worked out really well for me.

Ok, so i tried the op's settings, and i unplugged 3 hours ago, and I'm still at 100%.... I dunno if it's a battery reading bug, but if it's not...wow!
Also, since doing this tweak, i got an upload speed boost....i dunno if it's related..

Edit...it was a reading bug....it was a battery reading bug...i was actually down to 50....but the speed tests....still dunno how i got such high upload speeds.

CM9 Battery life

First of all, I want to thanks every developer whom make ours Evos looks like a new phone.
I have been using mikg since I rooted my 2 Evos. I tried cm7 and I went back to mikg because the sence. I used cm9 for 2 days and is so amazing. I do like it way more, even without 4g. It is so smooth, just the best ROM I ever tried. But, there is always a but, since cm9 is an AOSP I expect better battery life. In 2 hrs went from 95% to 15%. Today in the morning went from 100% to 75% in half Hour. So I had to went back to mikg cuz I have more than 24 hrs w/o charging. I tried to find some trick or any scrip or something to get better battery life but I did not find anything.
Please I will really appreciate any help on this.
Thanks!!!

Have you tried to flash the Mason SBC kernel with it? I think the cm9 port has a mason kernel baked in but it doesn't have SBC. I've been running the Mason I .15rc3 kernel with it and battery life has been great. Also, give the rom+kernel a few days to settle in before passing judgement on battery life. I've found that after giving a fresh install of a rom/kernel a few days the battery life will improve.

Yea try it out and let us know. Just remember, with SBC kernels, you want to let the phone charge for about another hour or so after it reports that it is fully charged in order to get the full SBC effect.

I get your advise and I have to tell you that I notice the difference in just 10 mins. Now we are talking about. I was off today so I decide to play with my Evo to test this kernel, I spend almost 5 hrs(straight) between playing with settings, browsing the internet, setting some apps and watching videos from the internet(2 hrs maybe) and I'm on 20% right now. I think that's pretty good. Thank you for the advice!!!

CM9 comes with a MANSON kernel, but in not the same one. The one that I flashed is the "I 15r3", means that is the 3rd released candidate so is not a final version yet. I'm not sure whats the one that comes with cm9, but I think is a basic version of Manson Kernel made for cm9.
Remember this are electronic devices, maybe whats works for me don't work for you and vice versa. This is a great example. The cm9 stock kernel works great for you, I didn't get the same as you, but I get it with another kernel.
