I have seen many complaints about the battery drain on the Galaxy SIII after the update. I have had a horrible experience myself. The capper for me was today. I got to work and had not even unlocked my phone all morning but the battery was dead. When I went to battery manager it told me that 88% of my battery life was used by my screen. How is that even possible when the screen wasn't even on for the two hours my batter lasted? This is the worst update I have ever experienced. I should have known to go read reviews before I did the upgrade but I was tired and not thinking straight. Verizon and Samsung need to fix this now.
