my droid mini will not hold a charge and will only turn on for a limited time it is extremely frustrating and i have taken it to the store and they say there is nothing they can do i am extremly insulted i pay my bill along with a lot of money for my phone now the phone gets really hott while charging which makes me assume that it is the battery now anyone with a mini knows that you cannot ruin the battery because the back of the phone does not come off is there anything that can be done about this without costing me more money
