The basic power-off method

To turn off your Samsung phone, press and hold the Power button (usually on the right side of the device) and the Volume Down button together for a few seconds. A menu will appear on your screen with options including "Power off" or "Shut down".

Tap Power off to shut down your phone completely. The screen will go black, and your phone will stop running. On some Samsung models, you may see a confirmation message asking if you're sure — tap it again to confirm.

The power button location varies slightly by model. On older Samsung phones, it may be on the top edge instead of the side. If you're unsure where yours is, check your phone's physical edges for a slightly raised button.

Key Takeaways

  • Press and hold the Power button and Volume Down button together until the power menu appears on your screen.
  • Tap "Power off" from the menu that appears, then confirm if your phone asks you to.
  • The Power button is usually on the right side of the phone, though older models may have it on top.
  • If your phone is frozen and won't respond, you can force it off by holding the Power button alone for 10 to 20 seconds.

What happens when you power off

When you turn off your Samsung phone, all running apps close, your screen goes dark, and the device uses almost no battery power. Your phone will not receive calls, texts, or notifications while it is off. Any alarms you have set will not go off.

Turning your phone off completely is different from putting it to sleep (pressing the Power button once). Sleep mode keeps your phone ready to wake up quickly, but uses some battery. A full power-off is better if you won't need your phone for several hours or longer.

If your phone is frozen or unresponsive

If your Samsung phone is frozen and the normal power-off method doesn't work, you can force it to shut down. Press and hold the Power button alone for 10 to 20 seconds without releasing it. The phone will vibrate and the screen may flash before turning off.

This forced shutdown does not harm your phone — it straightforward cuts power when ready instead of closing apps gracefully. Use it only when your phone is completely unresponsive and won't react to the normal Power + Volume Down combination.

Restarting instead of powering off

If you want to restart your phone rather than turn it off completely, use the same Power + Volume Down button combination, but tap Restart instead of Power off. Your phone will shut down and turn back on automatically, which can fix many minor software problems.

A restart is useful if your phone is running slowly, an app keeps crashing, or you're having connection problems. It takes about one to two minutes for your phone to fully restart and be ready to use again.

Turning off without using buttons

You can also power off your Samsung phone through the Settings menu if the buttons are not working. Open Settings, scroll down to General, then tap Shut down or Power off. The exact menu names vary by Samsung model and Android version.

This method is slower than using the buttons, but it works if your Power button is broken or stuck. You will still need to tap the confirmation message when it appears.

What to do before powering off

Before turning off your phone, close any apps you were using and save any work in progress. While turning off won't delete your data, unsaved changes in apps like notes or documents may be lost.

If you are powering off because you plan to be away for a long time, consider charging your phone first. When you turn it back on, it will use battery power to start up and reconnect to your network, so having some charge helps.

Frequently Asked Questions

Will turning off my phone delete anything?

No. Powering off your Samsung phone does not delete photos, contacts, messages, or any other data stored on it. Everything will still be there when you turn it back on. The only thing you might lose is unsaved work in apps you had open.

How long does it take to turn off a Samsung phone?

A normal power-off takes about 5 to 10 seconds from the moment you press the buttons until the screen goes completely dark. A forced shutdown (holding Power alone) is faster, usually 10 to 20 seconds. Restarting takes longer — typically one to two minutes for the phone to fully boot back up.

Can I turn off my phone if the battery is dead?

If your battery is completely dead, your phone is already off. You cannot turn it off further. Once you charge it and turn it back on, you can then power it off normally using the methods described above.

What's the difference between powering off and putting it to sleep?

Sleep mode (pressing Power once) keeps your phone ready to wake when ready and still receives notifications. Power off (Power + Volume Down) shuts everything down and uses almost no battery, but takes a few seconds to start up again. Use sleep for short breaks and power off for longer periods away from your phone.

My power button is broken — can I still turn off my phone?

Yes. Open Settings, find General or System, and look for Shut down or Power off. Tap it and confirm. This works on most Samsung models, though the exact menu path varies. If Settings won't open either, you may need to visit a repair shop.
