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.

I owe it to you for having me download kernel manager.
Well with CM7 and the x99 kernal seems to give me the best battery life with the SMARTASS governor. About 20 hours with medium to heavy use.

There is no link at this point, you have to do it via kernel manager. I'd upload it but I don't want to without bc's permission.
I haven't use any other "controllers" other than the one built into cm7... can I use that or is there a prefered one to change governers and such. Thanks!

Since CM7 lets you change governors right in its settings I uninstalled SetCPU for now, in theory I would think it would cause more battery drain but I don't know for sure. But yes I just changed it right in CM7. I changed the governor to interactive and set the max cpu frequency to 1036MHz.
Gonna try this out. I love CM7 but the battery is killing me. I pray this works.
Android system & cell standby seem to be the battery use culprit. I will give this a try though but don't really think its in the kernel. Ill report back...
Sent from my PG06100 using XDA App
This kernel seems to be really good about not sucking the battery while on standby for me, that seems to be the crown jewel of it all. Right Now I am at 14 hours off the charger with 29% left.. remember I was lucky to get 8 hours most days before using this kernel.
This is off-topic, but along the same lines: which kernels gave the best battery life for Sense?
+1 OP was right I flashed this kernel and so far so good on battery life

Honestly I didn't get much difference between x99 and bcnice20's 1.5GHz kernel so either of those two. Scarykernel SUV works well on Sense if your phone can boot it too.

It seems to be true. I'm def getting better battery life. I also calibrated my battery but I've done that before without any major change. So far I have 5 hours of quite a bit of use and I'm at 71% I would normally be around 55-60% by now. I wonder what the main difference is with the kernel...

Medium use.
On my Gingerbreaded Evo-Shifted Premium XDA App.
I'm currently running miui 1.8.12 with tiamat kernel 4.0.6 and getting bad battery life. I flashed tiamat because I red it improved battery life. I have an extended battery and only getting 7 hours with light usage. I have tried several of those battery tips but not much improvement any ideas. Also tired installing setcpu from here but it won't install.

Most of us are using the 3.3.7 kernel. MUCH better than the 4.06
I will try and give that one a try then. My battery already down to 70% and its been running for only 2 hours. I figured with an extended battery I should be getting better time then what I am.
At the end of this, I wrote really good technique for conditioning your battery. It helps!

which one are you running the sbc or regular kernel. I can tell you this with an extended battery my battery life with a custom kernel is not noticeable. I do notice better battery life though with my regular battery and sbc kernel from Tiamat

SBC is the way to go. Ignore the fear mongers still holding onto 1 year old scare stories about SBC. It's lovely to NOT have that 10% drop in the first 15 minutes....

I use overclock widget and have preferred that over setcpu from day 1. I honestly can use my phone a full day of txting calling emailing and some streaming music. I also use juice defender and have it set to only use internet on specific apps. Although I do have it on wifi all day at work and home.
With this said I can last a full day on my regular battery no problems. I also have the 3500 extended and although I can do 30 hrs on it, it does seem to suck battery life faster than expected but my stock battery does not tails off as fast IMO...
stock - 18 - 20 hrs
extended - 24 - 32 hrs

Not bad, though I can get your extended battery life on my stock battery, xp. And personally I underclock, and use only the governor setting built into CM7.

I'm running MIUI 1.8.5 and that came with CM Kernel 2.6.37.6 built in....Should I be switching to a different kernel??
You don't HAVE to switch, but a lot of us get better performance out of the custom kernels
I did decide to update....I went with the same one you have....3.3.7 w/ SBC, and I see a very noticeable difference in battery life....Thanks for the suggestion!

People say the best kernel depends on your phone but how can you tell? By performance? Battery Life?
I only have tried Franco and Matr1x and both are kinda the same for me atleast and I only get 3-4 hours of screen time with minimal use, no sync apps, wifi only, brightness down mostly all the way, greenify some apps, uv -100. Im trying to find the best kernel that helps with battery life and most people say its Franco or Matr1x and I already tried both...I've yet to try Faux, Trinity, or Harshs....Help

try them. the right one will feel right to you. it will feel best overall on your device and to you. if you were given five dishes of food that youve never tried before, or heard of, what would you do to decide which is best for you. youd try them. your taste buds will let you know. but everyone else that tried would have varying opinions as to which is best for them. they are all good, but our needs and expectations and usages all vary.
^^^ This is the only answer you need...
Any other response just means that this turns into an opinion thread for best kernel.

Hi xda family
What has everyone's battery life been so far on root?
Preroot I was getting over a day with 6sot and 16 percent
Android drain.
After rooting with the eng kernel it has dipped a lot with high android system drain. Have not used amplify and greenify yet. Just been used my tweaks I did on pd7 kernel.
Thoughts?
Amplify will probably help out a lot. I've seen others reporting the battery is worse after rooting as well. Hopefully someone nails it down and posts a fix. If not, I'll see what I can do once (if) I decide to root.
Yeah I can literally watch my battery % drop after root. I noticed 46% of use is the android system. I'm also getting lots of random reboots.
You guys rooted with an EngBoot that was not intended for daily use, this is one of the side effects.
Yeah the ENG-BOOT is a terrible way to achieve root. I really hope that this tiny victory doesn't cause people to stop looking for real root. The ENG-BOOT is not meant for daily use is going to cause lots of issues, it's designed just to push fixes to the system for an authorized repair shop.
The focus should have always been on the bootloader.

Wow 46 is high. To be honest for eng kernel it's been stable. No lag and reboots for me. I am debloating and doing a few tweaks and making it settle in some more. If I can get to 4 sot I will take that.
Also I have heard if you your governor set to on demand it will cause reboots. Using interactive and been solid.

TEK knows what he's doing, so I'm sure this will at least help with battery. This, plus Amplify and BBS+ should at least help get battery close to where it was before root.

+1 it runs a lot cooler than the normal stock rooted. And way smoother without have to tweak anything with kernel. It's basically plug and play.

I'm reodining because it was suggested to do when updating to texhd 1.5
dam we got root now? I didnt even know
With all the different tweaks now available through root, the battery life is quite excellent. The only concerning thing is how hot this phone can get at times (after a reboot, gaming, downloading an app) that I may be doing great harm to my batteries life in the long run.
okay so,
the engineering kernel's default governor is performance and that's the only thing that's causing the heat issues and thus, the throttling of the CPU cores to lower frequencies resulting in lag/stuttery performance. that's all you're experiencing. thinking that apps are using more/less battery than usual is silly.
after wiping data and cache and going through the horribly slow setup process, I used kernel adiutor to change the governor back to interactive (NOT ondemand) and let the phone finish settling/syncing. after 2 days, it's back to its silky smooth performance and all-day battery. I don't see anyone experiencing anything other than symptoms of the performance governor.
btw, it took the same amount of time for my phone to stop being laggy when I first bought it. so literally all you need to do is change your governor back to interactive if you want the performance/battery life you had before, and zero heat issues. antutu scores 110k-138k depending on temperature/throttling. just like it did before. battery gets 4:30-5:30hrs SOT just like it did before.
TL;DR

I used kernel aduitor too till I found out my big core were maxed at 1500 also just like the little cores and you can't change those with aduitor.
Once I installed kernel toolkit, I confirmed it.
So I bumped up the big cores max and got much more speed back. No heat here
Food for thought.
