Phone only charging when turned off
Hi I have an iPhone 7 that only charges when turned off. I have tried changing Tristar twice, Tigris once but still have the same issue. When plugging into a charging cable, ITunes recognizes it but does not show a charging symbol and no amps are drawn from a USB ammeter. However, when the phone is plugged in and turned off, the usb shows a power draw of about 1 amp. I have also changed Q2101. Any help appreciated. Thanks.
