iPhone 6s not powering on, but charging at 0.67A
Last day I’ve tried to charge my iPhone after it went completely black after consuming all its power. Surprisingly, it would not show any sign of charging and after several hours plugged to the wall, it would not power on, at all.
I tried to manually charge the battery and this sort of fixed the problem, making the phone power on, but when I tried to charge it via usb cable, it started to discharge rather than charging.
I checked the charging current with an Ammeter and it was showing 0.67A (note that my Samsung galaxy S9 is charging at 0.40A).
What would the problem be?
P.S. : I also tried to clean up the charging port.
Es esta una buena pregunta?
