I work for a company that manages a fleet of 1st gen iPad Airs and 6th gen iPads. I’ve recently been getting a lot of iPads returned to me because of suspecting charging issues. I think a number of these issues are due to faulty 3rd party cables/chargers. Is there a way to test a lightning port without removing the display of the iPad? I just want to test if the lightning port is drawing the correct current to charge the battery.
You can buy USB Current Ammeters and see if there is current being drawn ifixit even has one listed on its store. Regular charge current is usually in multiples of ~500mA. USB Mini Voltmeter
