Shailender Sharma , Dec 10, 2021 : Clean the USB Port - Charging problems may be caused by debris blocking the physical connections in the charging port. Dirt, dust and lint can get between the metal pins of the charging cable and charging port, preventing electricity from flowing. If this is the case, gently swab the connection port with a toothpick to remove any debris. Be careful not to damage the connector pins.
