Viewing Usage Statistics
Awareness of how you use your iPhone and knowing how long your 
battery typically
lasts can help you improve its battery life. You can view your iPhone 
usage statistics
by tapping the Settings icon on the Home screen and choosing 
General > Usage. Under
the "Time since last full charge" heading you'll see two items:
  Amount of time iPhone has been awake and in use since the last full 
charge. The
phone is awake when you're on a call, using email, listening to 
music, browsing the
web, or sending and receiving text messages, or during certain 
background tasks such
as auto-checking email.
  Amount of time iPhone has been powered on since its last full 
charge, including
the time the phone has been asleep.
