Unplug your device from the charger, then wipe with a dry cloth or gently shake your device (5-10 times) with the port facing downwards to release any excess moisture. Place your phone on a cloth in a well-ventilated area, or dry it with a fan.

Exposure to environments with high humidity may cause this. Try drying your device, and if your charging port is completely dry, restart your phone. Check that your device is placed directly in the center of the pad, without any obstructions in the way.
