Why won't my iphone 4s Charge WHEN! ITS ON! BUT charges when OFF?

Its also not being sensed when put into usb, is as if when the phone is ON it loses charing ability and USB ability.

It is possible that the battery is broken.

Take it to an Apple store for service.

  • Why does my iPhone 4 charge only when its off? I had my iPhone 4 for a year and a half. It's really cracked bad! I never had any problems with it charging but all of a sudden it stopped charging when its on, but when its off it charges. Could it be over heated cause I charge all night lots of times? It's not water damaged. I changed the charger, and the charger isn't the problem.
  • My iphone 4s won't charge on wall but charges only connected to computer? I got an iphone 4s which is used. I bought a charger today but the iphone doesn't charge on wall. Only in the pc.
  • My iphone 4s charger only charges when its off? I'm trying to charge & put music on my iphone but the thing is the charger only works when the phone is off and its on the wall. But i try doing the same method on my laptop but it wouldnt work.
  • Iphone only charges when its off/dead? So i have the iphone5c and starting yesterday when i plug it in to charge the phone it won't unless i turn it off and its dead but once it gets to 4% it will stop charging. it might be the cord since my cat chewed it but it still charges when off and it worked since before yesterday. Also I plugged it into the computer and it just said not enough power or whatever and i googled this and everyone said to reboot/reset it but i can't since theirs not enough charge to.
