HTC Evo 4g I want better battery life but I don't want the look or performance of my phone to change. Is it possible to install a different kernel only? And is the kernel what can improve battery life? My phone is rooted using the Unrevoked method if that matters. Also, if someone could tell me the info they would need to know about my phone in order to suggest a good kernel for battery life, I'd appreciate if you could let me know what details you need and how to find them. I sincerely appreciate any help anyone is willing to offer!
