So I rooted, but waiting to see some reviews on roms before I go that route (if at all). My main reason for flashing a rom would be for the kernel, and perhaps some other minor tweaks/hacks. Anyway, I fired up CPU and set the underclock to the minimum of 350mhz. Set it to interactive, and BOOM! significant instant boost to battery life. Seems to be working, but was curious if anyone has other feedback.
