We have received an iPhone 7 plus with charging issue and it would not charging with any USB cable and it was draining the battery so quickly.
On this iPhone 7 we’ve repaired broken data line on a second layer of the logic board after the customer tried to replace the LCD screen and accidentally used the wrong screw on the wrong screw hole and after that, because the screw was long it damaged the logic board and broke the touchscreen connectivity data line between CPU to LCD connector and because of that touchscreen wasn’t working at all. so we fixed the broken data line and touch screen starts working again.
