Can someone please explain to me in detail what exactly "awake time" and "up time" mean?? I am sooo confused. I unplugged my phone at 6:20am today with a full charge and it is now 9:52am. I have been running Pandora since 7am consistently. My battery is almost under halfway with bars..my uptime is 45:12:40 and my awake time is 16:07:05 (36%) ...anyone assist?
