My gf has a Thunderbolt and she has been having problems with the battery life, it usually does not last her an entire day. She has done the standard things like throttle the sync settings, adjust the display, turn off 4G and GPS. I was wondering if there are some other ways to help out battery life? How is the life while rooted and is there any easy root options on the horizon? I just looked at the rooting process for the Thunderbolt and it looks somewhat long. Any suggestions?
