Hi all; I'm a recently converted lifelong iPhone user so please be gentle. I couldn't be happier with my new GS3 but i'm concerned about the battery life. It's nothing like my old iP4. 5h 05m 15s battery usage 31% Battery left usage stats: 29% screen 28% android system 15% cell standby rest = various games & apps... no single one more than 9%. This seems REALLY REALLY poor. Can someone compare this with anything for me ? I have no point of reference and I need to know if i have hardware issues or if this is what it is. Thanks!
