20 - 30 minutos
The battery would barely last 4 hours and when it got to about 35% and you used a more power intensive program it would die suddenly.
The repair was nerve racking. I was sure I would break something or fail to get it apart or back together. When I got to step 6 I broke part of the #3 connector. This is an AT&T phone so it isn't a European model. I eventually got it apart an back together and it still works. The charge only lasts about 10 hrs. Is this a result of ios5?
Here's a picture of my broken, non-opening connector.
