I got this phone brand new on Thursday and I'm already having problems with it charging. Saterday night I put it on charge then I wake up Sunday morning and it says fully charged but there's atleast half the battery missing. When I plug it in it say fully charged. Then last night I turn off when the battery was low put it on charge over night wake up this morning the screen says fully charged. I turned the phone on and it says the battery is low! What the heck is going on with this thing its only 4 days old. Did I buy a headache of a phone?
