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.

(I was listening to Garbage's new single hehe)

And I took this picture after I got into the house


And I just took this picture.


What could be going on?

Quickly double tap the button on the bottom.
Check which Apps you have running in the background.
Hold your finger on one until they all start wiggling. Hit the "-" sign to turn them off.

That's probably what's draining your battery.

Alternative method it to totally power off (hold top button down until you get the red scroll and shut down).... and then turn the iPhone back on again. That shuts all apps down.

Had the same thing happen to me until someone showed me.

I did all of that

Lots of good tips and ideas here..

The arrow next to your percentage means something is accessing online data.

Ask to join networks off in Wi-fi? Bluetooth off? Push off?



Also check out my reply below to properly calibrate your battery. If you have not done this it may be giving you a false reading as to what is actually left.

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

Yeah, it's media. I'm on airplane mode.

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.

Is that Reccomendation for the iPad also?

Its probably a recommendation for anything having rechargeable batteries with memory (read: most of them=)
