Under Settings->General->usage, it lists your Usage and Standy time since your last full charge. Most of the day the phone sits in my pocket on standby. However, under usage it is saying 7 hours, 10 minutes (standby is over 10 hours). Is the phone doing something when its in my pocket I don't know about? I don't understand why it'd say 7 hours. It should be more like 1 hour. Maybe.
