After taking my phone to the ATT Store and being told my Battery was good but they could see that my phone was having bad power outage/reboots and that ATT would not change out the battery Even though their Website said they had the service for $89 , I went to the STLiPhoneRepair where it took 15 minutes to change the battery in my phone, Since having it changed I have not have an issue with it powering off again. Best money spent $30 to have the new battery put into the phone for me
