I replaced the battery and phone turned on. I put it to charge and it was taking a really long time to charge and also the phone got really hot.. When it eventually charged to about 80% I disconnected it and in less then an hour and without me using it phone kept on loosing battery percentage. Eventually it turned off and now when I connect it, it does nothing at all. Battery was new and this is the second time the phone does this to the battery. what can it be? Help!
