I need a good Rom and a kernel with the best battery life ASAP!!!!

Dude WTF. You will get a different answer each time. You.have to experiment. Each phone/user are unique. Therefore there is no one perfect.combination.

Everybody has an opinion on this. Experience has shown that each phone has differences in how well certain ROMS/Kernels work. Trust me, just try different ROMS and see which one you like and which works best on your phone.
After trying many I have settled on Myn's Warm 2.2 RLS5. It is smooth as butter and everything works well on it. I have also found Netarchy's kernels work well on my phone and give me great battery life, even with heavy usage.
Again, don't be afraid to experiment and see what works best on your phone. Always make a Nand back up before you start.

You could have used search to find any of the 6 threads a week that start up asking the same dumb question.
It's like asking "I need a car, what's the best one?"

Well, make sure you have SetCPU as fast as it will go... and ALWAYS keep wifi and bluetooth on. Set the screen to maximum brightness!
Seriously though, don't ask questions like that, nobody is going to want to help you.

Every persons experience is different man why do you ask this once a week lol. Just flash and test yourself bro its so easy a caveman can do it.

Yes, in the development section he has a thread dedicated to his under volt/over scripts. I use the more aggressive under volt scripts.

Give us some more details, when did you flash? How did you flash? Have you installed any apps lately?
My fault. Sorry. I'm running that CM7 19 VERSION. I am using the red theme from the market. I can't use juice defender simply cause it doesn't support gingerbread yet. I'm using 60676 prl. Can't even find the pri but I'm assuming it's still 1.77 unless cm came with 1.9.
Flashed it 24 hours ago. Haven't switched kernals cause I have had horrible experience with anything other than stock with myn's. I reinstalled all my apps and kik messenger is on lockdown with autostarts. So therefore it doesn't eat up partial wake time and doesn't open unless I do it manually.

Stock, until you get those issues ironed out. "Stock" sounds lame, but CM7s kernel is far from stock
After that, I use savaged-zen with much success. Though everyone will tell you that kernels behave differently with different phones. Spend a week trying a few for like 2 days at a time and see which one you like the most Also, play with the governor settings (under settings/cyanogenmod settings/performance). I personally use the SZ kernel with the "interactive" governor and find it to be the best balance between speed and battery life.
Interactive all the way man!! DATS DA BEST!

There is no best kernal... just flash and test for yourself. Some phones prefer CFS to BFS, some like heavy undervolting some don't.
Flash and try it out yourself.

Dev section, for AOSP look for the thread by viperboy. big [MOD] in the thread title.
If you wish to get it for a Sense tom, then search Caulkin.
Many kernals are undervolted already, this script makes your phone run at even lower voltages. Good luck, make a back up as you probably will boot loop a couple until you find a good stable voltage drop.

Kernel/Sense ROM question.

Hey guys, sorry if this has been asked before, I usually don't hang around the Evo 4G forums since I have a 3D. However, my wife has and Evo 4G and uses it quite a bit. Is there a kernel and or Sense ROM out that significantly increases battery life over stock? It doesn't need overclock or anything. Just stable with better battery life.
Thanks in advance!

There are many different roms and great kernels that fits great for some. I use (an example) EVOlvedroms. With that I use either more freedom kernel or chopsuey 9. Both work great for me and had excellent battery life plus stability. Check those out. Hope that helps.

Flashing a kernal from phone

I am currently running Lithid-cm's HTC EVO 4G Freedom V 0.9 (stock) kernal. I want to find a new one that is great and that I can install straight from my phone. I also could use some directions on how to do it.
TIA
Sent from my Swagged Out Stock EVO
Download your kernel of choice from phone, use some sort of file explorer app to make sure its named PC36IMG.zip and also make sure its on the root of your SD card, then turn your phone off and turn back on holding volume down or hold down power and hit reboot and see if you have a hboot option. After all that volume up when prompted then again. I haven't flashed a new kernel in a while but I think that covers it.
Sent from my PC36100 using xda premium
Aside from what he said, all the kernels for Evo are signed. They do not need to be PC36IMGs . Just wipe cache and dalvik, and flash like anything else thru recovery.

Well, I just installed it last night so it might be a few days before I notice the difference in full. As of now, It's a little snappier. It was really easy and quick to install. I was in line at Walmart and did it, by the time I had to pay I was able to use my phone again.

I can say that I have noticed about a 2% battery life increase and about a 5% performance increase. Of course I don't have a lot of apps and I use it light-normal now that I don't use Facebook. I also messed with my http and rstp and that helped with the 3g.

Why is finding a decent Rom for the Evo4G with 4G so darn hard!!!!!
What makes the Evo/Android OS so hard to incorporate into Roms?
If their are any 2.3.5 + 4.67 +4 G Roms that are worth trying let me know!!!!!!!!!!

This behavior happens due to the way in which batteries are charged. It happens on many ROMs and kernels for the 1st 10%. What is important is what happens after that. If you want to avoid it entirely the only sure-fire is to use an SBC kernel.

That makes you completely ignorant for making that statement. Yes it is harmful in the long run, and they don't include it because of that and the things that can happen to that battery that cam cause the user harm.
try swagstr SOS X, it is my daily driver and doesn't eat the battery up on mine.. You may also want to download a battery calibrator after flashing a new rom
