As a new iPhone user, I'd like to find all the best ways to save battery life now rather than find out at a later stage I could have been doing this all along. What tips would you give me to save on battery drainage on a day to day basis? When I'm at home and not doing anything the iPhone is charging. When I'm asleep, it is not charging, but lying on my bedside table, in standby mode (as I use it as one of my alarms). Turn off wifi/3g overnight? Turn off location services? Anything else?
