How do you know it is fully charged if it won’t turn on? I think there’s a little of backstory that needs to be said here. What happened to the device prior to this issue; was it dropped, damaged, repaired or came into contact with water? With what little you have said, the first thing to suspect is the battery. If anything happened to the phone, then it could also be a logic board issue.
