Charge flex cable contact melting
I just experienced something strange and i am hoping some of you out there have an answer.
I replaced the charging port dock connector flex cable on an iPhone 6 for a customer.
After i finnished i tested if the phone was charging and that the batteri percentage actually went up. And testing was successfull. iPhone 6 Lightning Connector and Headphone Jack
I gave the phone back to the customer and 1 day after hes calling me and saying the phone is not charging. I ask him if he have tried several chargers and cables and he said yes but non of them was working.
I went ahead and opened the phone today to check what was wrong. I suspected the battery might have some issues. I opened up the phone and pryed open the battery cable and the cable from the dock connector. At first sight everything looked ok but when it took a closer look at the connector on the motherboard it looked like one of the sides of it was melted. Pictures attached.
How is this possible ?
Is this a good question?
