So I'm pondering doing a reset to my phone to see if it helps with my battery life. My questions are: -Do I just do a factory reset, the option that can be found under settings? I saw someone war post a way to do a reset (master reset? I dunno). It involved typing in #'s and *'s. -Would I need to take out my SD card? -Anything else I'd need to do/know b4 I do this? Thanks a bunch!
