Samsung phone unexpectedly powers off

If your phone's battery is running low, features or apps that need more power may force the device to shut down unexpectedly. This feature is intended to keep the battery safe.

• Remove any detachable batteries and inspect them thoroughly. Check that the battery is genuine Samsung and that there is no damage to the battery or the pins in the compartment.

• If you are unable to remove the battery, reset the device by pressing and holding the Power and Volume down keys for 30 seconds.

• Remove any covers or accessories that may interfere with the device's buttons.

• Examine the Power or Side keys for regular movement. When you push the button, there should be a small but definite clicking sound. If the key becomes stuck, it may trigger unexpected shutdowns.

Only use an original Samsung charger and USB cable.

Navigate to and click Settings, then search for and choose Auto-restart at certain periods.

To disable Auto-restart, tap the switch at the top of the screen.

Alternatively, you may keep Auto restart enabled and use the schedule to control when your phone restarts to avoid surprises.

Certain apps might cause your phone or tablet to freeze, crash, or lag. Some programs can even interfere with camera performance, create audio problems, and disrupt network connectivity.

Safe mode disables all downloaded applications and runs just the original software that came with your phone or tablet, allowing you to establish if the problem is due to an app or the phone or tablet itself.

If the problems do not emerge when in Safe mode, they are the result of a downloaded software that should be deleted.

First, open the Power menu:

• On devices with a regular Power key, press and hold the Power key until the Power menu is displayed.
• On devices without a power button, swipe down with two fingers from the top of the screen to open the Quick panel. Tap the Power icon at the top of the screen.

Touch and hold Power off until the Safe mode icon is displayed. Tap Safe mode to start your device in Safe mode. If you've entered Safe mode successfully, you'll see Safe mode displayed at the bottom of the screen.

Use the phone or tablet to see if the issue has been fixed. If the phone or tablet is operating normally, a recently installed app was most likely causing the issue.

• If the issue is gone in Safe mode: One of your recently downloaded apps was likely the cause of the problem. You need to proceed to Step 4.

• If the issue still exists: Downloaded apps may not be the cause of the problem. You may need to reset the phone or tablet to the factory setting.

One by one, uninstall any apps you downloaded just before your phone or tablet began having the issue.

After uninstalling each app, restart the phone or tablet and check if it is working normally.

After uninstalling the app that caused the issue, you can reinstall the other safe apps you just deleted.

First, open the Power menu:

• On devices with a regular Power key, press and hold the Power key until the Power menu is displayed.
• On devices without a Power key, swipe down with two fingers from the top of the screen to open Quick Panel. Tap the Power icon at the top of the screen.

Tap Power off to turn off the device. Wait until the phone or tablet completely turns off, and then press the Power key again to turn it on. See if the issue has been resolved.

• Make sure to back up your phone or tablet. All data and settings will be erased.
• Write down the username and password for the account that you used to back up your data.
• We recommend having your phone or tablet plugged into the wall charger during the reset process because it may take up to an hour.
• If you have encrypted the SD Card inserted into your phone or tablet, make sure to decrypt it before the reset. Navigate to Settings, search for and select SD, and then tap Decrypt SD card.

When the phone or tablet reboots, it will have its default factory settings. Now you will need to go through the initial setup to finish setting up the phone or tablet. The phone may require you to enter your Samsung or Google account information to complete the setup

Before installing any apps, make sure that your phone or tablet is functioning normally.
