I know it all depends on what you do and the settings, but I had my iphone replaced because the home bottom stopped working and I feel this iphone battery just drains. I set it up new so it cant me the restore from back up issue. I have brightness around 45% and adjust to room. Have 3 emails all with fetch every 30(one is exchange for calenders and contacts also) and have just been checking twitter every 30 mins and playing line birds for max 30 mins total so far today. Also maybe sent around 10 texts and received around 15. Unplugged it at 7:20 to leave for work and this is what im at already You guys think this is normal or should i try and get another replacement?
