as the title says
best kernel for maximum battery life
There is no best. You have to try all. But for my usage Franco is best. For your case this might be different.

Im looking to flash a new rom and im wondering which rom as the best battery life. i currently have cm7 but i get horrible battery life.
every phone is different, some say CM7 gives better battery life, but my experience shows that the stock based ROMs last longer. So basically you have to try to figure it out.
I have found using Faux's latest kernel (23), undervolting and setting the governor to powersave, I have been getting good battery life with CM7.
I am currently using Ligux and am happy with my battery life (~12hrs).
Neutrino EE has given me the best battery life so far. Make sure to calibrate your battery after flashing.
So I've been trying various combinations and I have not gotten any "good" battery life out of any? Any suggestions?
ICS roms conserve battery in my opinion. (They all usually come with a kernel that is required)
^ agreed i seemed to get pretty good battery life from clean rom and there seems to be only the stock kernel for that and an OC one
Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share
I have been using MeanRom and MikVirgin off and on. I like MikVirgin alot better, and want to use it full time, but the battery life is terrible. MeanRom makes my battery last at least twice as long, but I get worse reception. I read somewhere that the great battery life has something to do with turning off one of the cores while the screen is off. I'm not an expert, but i think that is a kernel issue.
Is there a kernel that I can use with MikVirgin that will give me battery life similar to MeanRom?
That's a relatively hard question to say which kernel gives good battery life. Because no one kernel by itself can save more battery life than the other. Some do handle the tasks and compliment the CPU better than others. It all boils down to how your kernel is set up, what governor you use when your screen is on. What frequencies on and off, overclocking the CPU drains battery quickly. Having both cores online and one off when screen off. What I/o scheduler in combimation with a governor. It really depends on how you use or phone to best suit your needs, not one combination is best. While maintaining good battery is a must sometimes you end up sacrificing from performance and your phone suffers with lags. From these experiences I have found that the cool kernel and the forbidden kernel give good balance and stability in most sense roms. Along with meanrom and common sense. Those two roms I have found to give good bettery life. You just got to experiment. While one combimation of Rom, and kernel work for one persons EVO may not be the same on another persons.
What is the best custom rom for both battery life and performance nowadays?
