Galaxy S6 Not Charging: Battery, Charger & USB Issues Explored - Possible Solutions

Hello, when connecting the charger from the phone there is no reaction. The phone currently has batteries charged in a few%. The charger is 100% efficient. However, after switching off the phone and attempting to charge, the battery symbol appears on the display for a few seconds, then the backlight of the keys will flash and that's all. The phone is still not going to be charged. Is the battery damaged or maybe it's a software issue? Please help. Thank you very much and best regards.

edit:
I would also like to add that the problem is identical when I try to load a computer via a USB port. The telephone does not communicate with the computer.

Micro USB socket for replacement. The exchange is not easy because you need to download the display.

But I will also add that I can not charge it with an induction charger, with my second galaxy s7 charging with no problem

edit:
Problem solved. After several tests, he detected an induction charger. USB charging also started working. I have no idea what the reason was, someone can explain to me how to verify it?
