When phone is off and I plug it in to outlet the phone turns on instead of charging
What sticks out to me is that your battery status says "Not charging" Instead of discharging. I feel like your phone may recognize that the charger is plugged in, but may have some error in the battery/phone itself. I feel like your phone may just be translating the charger power directly into the phone itself, and is not able to charge the battery. If this is the case, it IS a hardware issue. Sorry that there isn't much you can do.
