MacBook Pro 16 2019 charging issue

• Hi,

In my MacBook Pro 16 from 2019, there is an issue while charging. The situation is that while I plug the USB-C charger, it randomly stops and starts charging. This is very annoying as the screen gets dark and there is a specific sound. Probably, this is also not good for the battery.

What I did so far was:

resetting SMC

• changing USB-C cable and charger (BTW, in the Apple store, They sold me a new charger with cable, and the problem is still there so I wasted money)

• changing electricity sockets (different rooms, different buildings, even different countries :)

• turned off battery loading in the settings

• n̶e̶w̶e̶s̶t̶ ̶i̶O̶S̶ ̶v̶e̶r̶s̶i̶o̶n̶

Nothing helped. What I can do more there?



MacBook Pro 15″, macOS 10.15

iOS is for iDevices...iPhone, iPad, iWatch etc

what exact macOS?

old issue, new issue, what changed?

You run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.
