Why does the cooling down popup appear on Galaxy device

Last Update date : Oct 10. 2021

When you use features or applications that require more power or use them for extended periods, your device may temporarily heat up due to increased battery consumption. When the device heats up, your phone will display a message that says "Device cooling down" and will automatically change settings to prevent damage from overheating.

Be sure to check if your device's software and related apps are updated with the latest version. Please check how to update your mobile device's software in the following order. 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions. 

Stop using your phone.

If you receive the "Device cooling down" message, put your phone down and do not use it until it has cooled sufficiently.


Let your phone cool itself down.

The phone will automatically change these settings to prevent overheating:

  • Screen brightness may be reduced.
  • Running apps may be closed.
  • Overall performance may be limited.
  • Wi-Fi and cellular networks may be disconnected.
  • The Camera app may stop or close with the message "Exit Camera. Battery temperature too high."
  • Charging may stop.

This is a normal operating condition to prevent damage to the device. Wait for the device to cool down and then begin using or charge the device again.

Do the following when the device heats up:

  • Keep the device updated with the latest software.
  • Conflicts between running apps may cause the device to heat up. Restart the device.
  • Deactivate the Wi-Fi, GPS, and Bluetooth features when not using them.
  • Close apps that increase battery consumption or that run in the background when not in use.
  • Delete unnecessary files or unused apps.
  • Decrease the screen brightness.
  • If the device overheats or feels hot for a prolonged period, do not use it for a while.
