Turning off an iPhone 15 is quick and simple. You can press and hold the Side button plus either Volume button and slide to power off, or go to Settings, General, and tap Shut Down to do the same thing without buttons. If the phone is frozen, you can force restart to get it back to normal. This guide shows each method step by step, plus tips and answers to common questions.
How To Turn Off iPhone 15 – Step by Step Tutorial
These steps will show you the normal ways to power off your iPhone 15, a button-free option in Settings, and what to do if the phone is unresponsive.
Step 1, Press and hold the Side button and either Volume button until the power off slider appears.
Hold the Side button on the right edge, and press either Volume up or Volume down at the same time, keep holding for a second or two.
When the screen displays the power off slider, stop holding the buttons. Do not hold them too long, or you may trigger Emergency SOS.
Step 2, Drag the “slide to power off” slider to the right to shut down.
Touch the slider labeled Slide to Power Off and swipe it fully to the right.
This moves a visible control across the screen and begins the shutdown sequence. Make sure your finger follows the slider until the screen changes.
Step 3, Wait until the screen goes completely black and the device is clearly off.
After sliding, wait a few seconds for the screen to go dark and for any spinning indicators to stop.
If the display turns black and does not respond to taps, the iPhone is off. If the screen lights back up, repeat the slider step.
Step 4, Open Settings, tap General, then tap Shut Down to access the power off slider without using buttons.
Go to Settings, tap General near the top of the list, and then choose Shut Down at the bottom to show the same slider.
This method is useful if your Side or Volume buttons are sticky or if you prefer tapping rather than holding buttons.
Step 5, If the phone is unresponsive, force restart by pressing Volume Up, then Volume Down, then press and hold the Side button until the Apple logo appears.
Quickly press and release Volume Up, then quickly press and release Volume Down, then press and hold the Side button until you see the Apple logo.
A force restart does not erase your data, it simply forces the device to reboot. Use this when the screen is frozen and the normal power off slider will not appear.
Step 6, Enable AssistiveTouch in Accessibility to power off using the on-screen menu if buttons are broken.
Go to Settings, Accessibility, Touch, then AssistiveTouch to turn it on, then use the AssistiveTouch menu to access Device, More, and Restart or Lock Screen.
AssistiveTouch gives you a floating on-screen button that replicates hardware controls, handy when a physical button does not work.
After you complete these steps the iPhone will either power off fully or restart, depending on the method you used. If you used the power off slider or Settings, the device remains off until you press the Side button to turn it back on. If you used force restart, the phone will reboot and show the Apple logo, returning to the lock screen.
How To Turn Off iPhone 15 – Tips
- Enable AssistiveTouch before a problem appears, so you have a button on screen if hardware fails.
- Use Settings, General, Shut Down when you want to avoid holding buttons, or when buttons feel sticky.
- Do not hold the Side and Volume buttons too long, or Emergency SOS may activate, calling emergency services.
- If the phone is charging, you can still shut it down, but it will not charge while powered off.
- Force restart is a reboot, not a shutdown, so use it only when the phone is frozen or unresponsive.
- Keep your iPhone’s software updated, as updates can fix power and button related bugs.
- If your iPhone will not turn off or on at all, try charging for 15 minutes and then attempt a force restart.
How To Turn Off iPhone 15 – Frequently Asked Questions
What is the simplest way to turn off my iPhone 15?
The simplest way is to press and hold the Side button and either Volume button until the power off slider appears, then slide it to power off.
This is the standard, user-friendly method Apple designs for quick shutdowns.
Can I turn off my iPhone 15 from Settings?
Yes, open Settings, tap General, then tap Shut Down to reveal the power off slider without using the physical buttons.
This is helpful if your buttons are damaged or you prefer using on-screen controls.
Will shutting down my iPhone delete any data?
No, shutting down your iPhone does not delete apps, photos, or settings, it just powers the device off normally.
Data remains intact until you intentionally erase or reset the device.
What if my iPhone 15 is frozen and will not show the power off slider?
If the screen is frozen, perform a force restart by pressing and releasing Volume Up, then pressing and releasing Volume Down, then holding the Side button until the Apple logo appears.
This forces the device to reboot and often clears temporary glitches.
Can I turn off the iPhone while it is charging?
Yes, you can power off the iPhone while it is plugged in, but it will not charge while it is off unless the charging hardware provides power to the battery while the device is shut down.
If you need it to stay charging, leave it on or plug it into a proper charger that supports charging while off.
Will Emergency SOS be triggered if I hold the Side and Volume buttons?
If you hold the Side and Volume buttons too long, Emergency SOS may activate, which can call local emergency services and send your location to contacts.
