I recently purchased a brand new iP5 from AT&T with contract and thus far its truly been a great experience in every category except battery life. I set up the phone with a backup of my iphone 4. My iP4 had amazing battery life, rarely going below 40% in a day and usually going a day and a half before requiring a re-up. My iP5 goes from 100% to 20% in a few hours. I use it to text, browse and listen to music but not at the same time and not for long periods of time. It gets no more use than my iP4. The only exception to this is when I'm talking on the phone. Just now I had an hour long phone conversation on 30% battery and it only dropped to 25% (which was normal for the 4) Any suggestions? I would hate to take the phone to be replaced as its otherwise a great phone but I will do it if necessary. It doesn't seem it will do me much good if it constantly needs to be plugged in! Thanks!
