6s Plus pulsed charging.
I just received a bad iPhone 6s plus board with the following symptoms:
Not recognised by PC,
Pulsed charging: 3,8V pulse then for about a second no voltage on battery connector.
The above repeats as long as i try to charge it.
When off, board draws 0,04A. Nothing heats up, no short on PP_BATT_VCC or on PP_VCC_MAIN.
When i try to power on, board draws 0,20A at 4V for about 1sec. and then back to 0,04A.
I should mention that U5101_RF is missing. I guess it should start without this?
