What to do when your Samsung Galaxy device will not charge while connected to a PC

Check your charger and charging cable

Using incompatible or damaged charging accessories may cause slow charging, charging interruptions, or charging failure.

Check the charging cable connection

If the charging cable is not connected properly, the device may not charge normally.

  • Disconnect the charging cable from the Galaxy device and reconnect it securely to the charging port.
Caution
Damage caused by user misuse or chargers outside the warranty period may require purchasing a new charger.

Check for charging cable damage

A damaged charging cable may prevent normal charging.

  • Try charging the device using another compatible Samsung charger and cable.
  • If charging still does not work, visit a Samsung service center for hardware inspection.
