How long the battery have to charge for firs time

its your battery u should get a new one

You need to replace battery. Battery is going bad and not holding a full charge. Your phone will say full charge, because battery is fully charged to the capacity that it has left. Buy these on ebay, really cheap to buy them there.

Your battery might be bad and you need a new one or your battery port is bad and needs to be replace.

it means you have a fualty battery what you need to do is get a hold of a at&t store or carrier and get a new battery and that should fix you problem
