The quickest way to turn off your S23
Press and hold the power button on the right side of your phone for about three seconds. A menu will appear with options including "Power off". Tap "Power off" and the phone will shut down completely within a few seconds.
This is the standard method and works whether your phone is locked or unlocked. You do not need to be on the home screen or in any particular app. The entire process takes less than ten seconds from start to complete shutdown.
Key Takeaways
- The power button is on the right edge of the S23, and holding it for three seconds brings up the power menu.
- Tapping "Power off" from the menu shuts down your phone completely, which is different from putting it to sleep.
- If your phone is frozen or unresponsive, you can force it off by holding the power button and volume down button together for ten seconds.
- Powering off completely stops the battery from draining, which is useful if you will not use your phone for several days.
- A full power cycle by shutting down and restarting can fix performance issues and clear temporary files.
What happens when you power off versus sleep mode
Powering off completely shuts down all processes and stops the battery from draining. Sleep mode (pressing the power button once) keeps the phone ready to wake up when ready when you press the button or receive a call, but the battery continues to drain slowly over hours or days.
Use power off when you will not need your phone for hours or days, or when you want to troubleshoot a problem. Use sleep mode during your normal day when you just want the screen to turn off but need to stay reachable. Over a week, a powered-off phone will retain far more battery than one left in sleep mode.
Force powering off a frozen phone
If your S23 is not responding and the normal power-off method does not work, hold the power button and volume down button together for about ten seconds. The phone will vibrate and the screen will go black. This forces the phone to shut down even if it is frozen or stuck on a single screen.
After a force shutdown, wait a few seconds, then press the power button once to turn it back on. This often fixes apps that have stopped responding or a phone that has become sluggish. A force shutdown is safe and does not delete any data.
Powering off before a restart
If you want to fully restart your S23, power it off completely using the menu method, wait five to ten seconds, then press the power button to turn it back on. A full power cycle clears temporary files and can fix performance issues like lag, app crashes, or connectivity problems.
You do not have to wait between shutdown and restart, but waiting a few seconds gives the phone time to fully discharge any remaining power in the system, which makes the restart more thorough. Many performance issues resolve after a single full power cycle.
Scheduled power off using settings
Your S23 can turn itself off automatically at a time you set. Open Settings, go to Device care, then tap Battery. Look for an option called Scheduled power on and off or Auto restart depending on your software version. Toggle it on and set the time you want the phone to power down.
This feature is useful if you want your phone off during sleep hours or during work without having to remember to do it manually. The phone will power back on at the time you set as well, so you can have it ready to use at a specific hour each day. This also helps extend battery lifespan by giving the phone regular complete shutdowns.
What to do if your phone will not power off
If the power menu does not appear when you hold the power button, try the force shutdown method instead: hold power and volume down together for ten seconds. If that does not work, plug the phone into a charger and wait a few minutes, then try again. Sometimes a phone that is critically low on battery will not respond to power commands.
If your phone still will not respond after charging, it may have a software problem that requires a factory reset or service. Contact Samsung support or visit a carrier store if the issue continues after multiple restart attempts. Keep your phone plugged in while you contact support so the battery does not fully drain.
Frequently Asked Questions
Is it bad to power off my S23 regularly?
No. Powering off your phone regularly does not damage it. In fact, a full shutdown and restart can improve performance by clearing temporary files and resetting processes. You can power off your S23 as often as you need to without wearing out the hardware.
Will I lose data if I power off my phone?
No. Powering off saves all your data, photos, messages, and settings. Nothing is lost when you shut down. The only time you lose data is if you perform a factory reset, which is a different action that you have to choose deliberately from the settings menu.
How long does it take for the S23 to power off?
Usually two to five seconds after you tap "Power off" from the menu. If it takes longer than ten seconds, the phone may be processing something in the background. Force shutdown using power and volume down will shut it down faster if you are in a hurry.
Can I power off my S23 while it is charging?
Yes. You can power off your phone while it is plugged in. The charger will continue to supply power to the battery even though the phone is off, so the battery will charge normally. When you power it back on, it will have whatever charge it accumulated while off.
What is the difference between power off and restart?
Power off shuts down the phone completely and leaves it off until you press the power button. Restart shuts down the phone and then when ready turns it back on automatically. Both clear temporary files, but restart gets your phone running again without an extra step.
