Quick answer

Your Motorola has detected moisture and disabled the USB port for safety, so charging or USB connections stop. Unplug it immediately, shake it gently with the port facing down to remove excess liquid, and let it air dry completely before trying again.

Safety first

Stop and check this first

  • Do not put objects into the port to dry it and do not heat the phone to speed up drying.
  • Do not connect a charger until the phone has air dried completely; Motorola says to unplug immediately and let it dry before trying again.

Safe checks you can perform

  • Unplug and remove excess liquid
  • Let it air dry completely and try again
  • Restart and test another cable or computer

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Motorola support if the port stays disabled
  • Do not attempt this professional task: Liquid damage assessment at authorized service

What it means

Motorola's user guide for the motorola edge 2026 says that if the phone detects moisture, it will disable the USB port for safety. Charging and USB connections such as file transfer stop until the port is dry. Motorola's steps are to unplug the phone immediately, shake it gently with the port facing down to remove excess liquid, and let it air dry completely before trying again. Other Motorola models may describe it differently in their own guide. Disabling the port is a protection; it does not prove the port is damaged.
