Weird charging behavior of my iPad pro
Recently, I found weird charging behavior of my iPad pro(9.7, 256, cellular model, iPadOS 14.3).
My iPad doesn't start to be charged when the screen is on.
The indicator icon on the screen says that it is charging but I measured that the current was 0 amp!
Only after the screen is off, real charging begins with proper current.
Then I can turn the screen on with my iPad being charged.
DFU/restore didn't make any changes.
neither did Hard reset.
Is it OS problem?
