Okay even to this day I see a lot of complaints about the Evo's battery. There is only 1 solution - the rest are fake placebo effects. If you hate your current battery life and have tried everything else then this is for you.
Requirements: Root + NAND access.
1) Root your phone. Go to xda-developers and search the Evo forums. It literally took me 20 minutes to go from stock android to rooted custom rom android - reading time included. If you cannot figure out how to root based off of the countless tutorials, then don't try.
2) Install a custom ROM and kernal. It is extremely important you install a custom kernal!!! Stock kernals have overclock/downlocking issues.
I recommend this rom:
[ROM] CyanogenMod-6 - No Sense at ALL! - V6.0.0-RC1 (07/25/2010) - xda-developers
with this kernal:
[Kernel] CM6-Snap-v5! UV/OC/Compcache - xda-developers
If you want to try something else go here and browse under ROM/kernal section: EVO 4G Android Development - xda-developers
3) Download SETCPU from xda-developers.com for FREE or support the developer by buying it from the android marketplace. Do NOT buy it right away unless you are running a stock rom.
Link to download from XDA: SetCPU for Root Users [2.0.2] This *actually* changes everything. 08/02/2010 - xda-developers
4) Stock settings are reported to work the best. Max = 998 and min = 256. I personally set the max to 500 unless I am doing heavy flash websites and min stayed 256 or less and I have gotten more than a days worth on heavy usage.
This is the ONLY permanent fix to the battery life you can do. All other methods that are used in stock (non rooted) android will only give you minimal battery increases that can fluctuate easily. The custom kernal and rom eliminate the BS apps as well as undervolt your stock vcore to give you incredible battery life.
This thread is to give a heads up. I don't want to hear any crying or complaining. In my experience rooting has been nothing but a success and very very easy to accomplish. Even if you brick it there are numerous ways to unbrick. I honestly believe the benefits outweigh the risks in this situation - prolonged battery life, 30 FPS cap removed, faster speeds, more apps, more customization, etc etc.
If you don't want to root - I don't need to hear about it in this thread. Thanks.
