I've seen scattered discussion about this in various threads, but I thought it would be nice to have one thread where we can discuss ways to wring out more battery life without sacrificing performance. Jrummy built a hell of a ROM here, so we're really just guilding the lily, but why not, right? I switched - just because I could, really - from Chevy's ULV 1g to P3's LV 125-900 and battery life went horribly wrong. I lost 50% of the battery in four hours of light usage with the screen mostly off! Switched back and battery life got much better. I guess the first question is, which kernels have you found to be the absolute best balance of power, speed and battery life? And next, are you using the new SetCPU and if so, what profiles are you using?
