I'm running Myn's Warm 2.2 RLS 5 with netarchy-toastmod 4.3.4-cfs-havs-more sbc kernel. Along with the Overclock Widget, I've been able to easily get over 17+ hrs with very moderate use out of my Evo. My question is regarding undervolting. I've done some research and have 3 questions: undervolting is done via a new kernel which would mean I would have to discard my existing kernel, correct? For Sense based Roms, what would be a good undervolting kernel? Why would anyone want to Overvolt? Thanks!
