What to do if your Samsung Galaxy device turns off unexpectedly
It can be inconvenient and frustrating when your Galaxy device powers off unexpectedly, especially if you are in the middle of using it. Follow this guide to identify what is causing your device to shutdown and how to keep it from happening again.
1. Close apps that consume the most battery
If your Galaxy device is low on battery, apps that require more power may force it to power off unexpectedly.
- Close apps
Step 1. Tap the Recents button.
Step 2. Swipe up on the screen to close an app.
- Set Background usage limits
Step 1. Open Settings > Tap Battery.
Step 2. Tap View details.

Step 4. Tap the switch to enable Background usage limits.
Note: Updates and notifications may be delayed if you enable Background usage limits.
2. Check the Power or Side buttons
- Remove any case or accessories that may cover the device buttons.
- Pressing a certain key combination for more than 5 seconds will power off the device.
- Check the Power or side buttons to ensure they move smoothly. When you press the buttons, you should hear a small but distinct clicking sound.
- If a key is jammed, it may cause the battery to drain quickly by frequently turning the screen on and off.
3. Charge the device with a Samsung charger
To avoid power and charging issues, it is recommended to use an original Samsung charger and USB cable to charge your Samsung Galaxy device.
The Auto restart feature helps to keep your Samsung Galaxy device in good running condition by restarting your phone periodically. It can be enabled and disabled as needed and will only occur when the device is not in use.
Step 1. Open Settings > Tap Device care.
Step 2. Tap Auto optimisation.
Step 3. Tap Auto restart.
Step 4. Tap the switches to enable or disable the Auto restart feature and set a schedule.
1. Open the power menu.
- On devices with a standard Power key, press and hold the Power button until Safe mode is displayed.
- On devices without a Power button, please follow the instructions below:
Step 1. Swipe down on the screen twice to open the Quick panel > Tap the Power icon.
Step 2. Long press the Power off button.
Step 3. Tap Safe mode.
2. Use the phone to determine if the issue has been resolved. If the phone operates normally, then a recently installed app is most likely the cause of the issue.
- If the issue is resolved while in Safe mode: you should uninstall recently installed apps.
- If the issue remains while in Safe mode: you may need to make an appointment with a Samsung Service Centre.
3. Restart the device to return to normal operating mode.
