Not powering on with plugged in
Hi, I have a bit of an unusual one.
I have an iPhone 5c that isn't recognising the power cable when it’s powered off. If the phone is on everything works as normal, but if the phone is off, nothing.
I have tried different batteries and charging port to see if they have any affect with no success.
A bit of history, phone has had a screen replacement. No signs of moisture/water.
Original owner said they had always the apple wall plug but had used 3rd party usb cables.
My initial though is maybe a U2 ic but could do with some other input before I go down that path.
Any and all ideas welcome, thanks in advance.
Is this a good question?
