Hi I have strange problem with my ip5s. It is working flawlessly until i plug it into charger. Then it starts to restarting. Even unplugging doesn’t help. Only when I leave it untill it will be 100% charged and then i force reset, it will start working normally again. Any idea?
Unless the battery is in a very poor condition it sounds as if the logic board charging circuit got damaged. Did you use a non original charger or was it plugged in a car charger ? If that’s the case you possibly need the phone to be taken care by someone experienced in logic boards repairs.
