Loc: Teetering between IL and AZ
When I left the house to go to school this morning the battery was at 94%. When I got off of the bus and into school it was at 72%. This is through a half hour bits ride with nothing being done on the iPhone but listening to music.
Its also getting really warm, so I decided to turn of location services before I left to see if it would help. It didn't, so before class started I turne on airplane mode. The battery stayed at 72% for the remainder of te school day.
When I got on the bus at 3:10 I turned off airplane mode. I took this picture 15 minutes later to show how much the battery dropped.
Isn't that a different arrow? I'm pretty sure it's for media playback. And the iPhone itsself is getting pretty warm. I had to take the case off
That's right, it's media playback.
Follow these instructions to calibrate the battery and see how that goes.
Running it down till it shuts off then recharging it to 100% helps to calibrate the little computer chip in the battery so you know better exactly how much battery life is left.
Apple recommends doing it once a month, also any time you charge it letting it sit in the 100% charged state for at least 20 minutes or so will give you more battery run time. It does a trickle charge sort of thing at the end.
BTW when you run it down till it shuts itself off it takes a few minutes, 5 or so, to turn itself back on. The battery needs to get to a certain charge level before it will reboot.
