So, I have a droid 4. Just got ICS about 6 days ago I think, and wow. My battery. Its life span has dropped. So i've been looking into options like undervolting. I thought about romming completely, but every time I go looking for roms for the 4, I always find ports, or stuff that may or may not work. I've rooted my phone. Has been since the day I bought it. But when it comes to undervolting, i'm having a hard time finding a guide specificly to the droid 4. Any one point me in the right direction?
