I have a strange problem with my iphone 3g. It is charging only when is totally uncharged (flat) but after it boots up (it turns up just about 15%) it is stop charging (icon of charging disappeared). Some technician tells me it is broken (exactly he said cracked) the board of the iphone but i don't think so. It is possible to be the battery problem? Because when I changing the backplate I bend a little my battery 1 centimeter from the top.
Thank You for help.
