Iphone runs out of battery fast?

I keep my iphone on charge all night till its on 100% and ten unplug it and 10 minutes later it turns off so i have to plug it back in again for it to turn on and wehn it turns on it has only lost like 2%.so i'm not quite sure what's wrong and not sure if i should replace the battery?

Go to your market and get task killer and use that! If not go to the store and ask what's wrong. They'll help

I agree with the other poster about getting a task killer if that doesn't help I'd look into options on getting a new battery. Sometimes a new battery is all it needs.

  • When your 2 year plan runs out on an iPhone? Well my 2 year plan on my phone is time. I can upgrade to a new phone but i have to give the people my old phone but its really damaged. It got ran over by a truck.long story. But my question is when you give them your old phone does it cost u money if it has been damaged because i didn't pay for the full phone only for the 2 year plan.
