So i purchased an iPhone SE, and the phone runs fine, it turns on, touch ID works, its completely intact, the only thing that's been changed is the original battery, however the phone doesn't charge. I plug it in and i get the lightning bolt in the battery but the phone just doesn't take a charge, more like the phone lingers at whatever percentage the battery was already at. Does this mean the logic board is damaged and i have to write the phone off, or should i replace the lightning connector board?
