Turning off an iPhone 15 is quick and simple. You can press and hold the side button plus either volume button, then slide to power off. If you prefer menus, open Settings, go to General, then tap Shut Down and slide. If the phone is frozen, use a force restart to get it back under control. This short guide shows both main methods and safe backups so you can power off the iPhone 15 with confidence.
How To Turn Off iPhone 15, Step by Step
These steps will show you how to shut down the phone using buttons, through Settings, using AssistiveTouch when buttons are hard to use, and how to deal with an unresponsive device. Follow the one-sentence step lines, then read the short paragraphs for helpful context.
Step 1, Press and hold the side button and either volume button until the power-off slider appears.
When the slider appears, drag it from left to right to turn the iPhone off. This is the fastest, most common method and works whether you are using a case or not. If you change your mind, tap Cancel or press the side button to get back to the home screen.
Step 2, Open Settings, go to General, then tap Shut Down and slide to power off.
This menu method is handy when your side button or volume buttons are hard to press, or when you prefer tapping through menus. Go to Settings, tap General, scroll down and choose Shut Down, then swipe the slider. It is the same final step as the button method, but without using physical buttons.
Step 3, Enable AssistiveTouch in Settings to use on-screen controls if your buttons are damaged.
AssistiveTouch gives you a virtual button on the screen that can replicate many physical button actions. Turn it on in Settings, Accessibility, Touch, AssistiveTouch, then use the on-screen Device menu to access lock and restart options. Note that AssistiveTouch may offer Restart, which reboots the phone rather than leaving it powered off, so use the Settings method for a full shutdown if needed.
Step 4, If the iPhone is frozen, force restart by pressing Volume Up, then Volume Down, then holding the side button until the Apple logo appears.
A force restart will not power the phone off for long, it forces the device to reboot and can clear temporary freezes. Use this only when the screen is unresponsive and the regular shutdown methods do not work. If your goal is to fully power down after a freeze, let the phone boot up and then shut it down using Step 1 or Step 2.
After you complete the shutdown action, the iPhone screen will go black and remain off until you turn it back on. To power it back on, press and hold the side button until you see the Apple logo. Your phone will return to the lock screen after the startup process finishes.
How To Turn Off iPhone 15, Tips
- Use the button method for speed, it is the fastest way to turn off your iPhone 15.
- If your phone is in a pocket or bag, confirm the slider appears to avoid accidental touches.
- Keep Settings, General, Shut Down in mind if your buttons are stiff, broken, or you use gloves.
- Enable AssistiveTouch before you need it so you have an on-screen backup when buttons fail.
- If a force restart is needed, remember it restarts the phone rather than keeping it off.

Frequently Asked Questions
Can Siri turn off my iPhone 15?
No, Siri cannot power off the iPhone directly for security and safety reasons. Siri can lock the screen or perform other tasks, but shutting down the device requires direct interaction with the buttons or Settings.
What if the power-off slider does not appear?
If the slider does not appear, make sure you are holding the side button and a volume button together for a second or two. If that still fails, use Settings, General, Shut Down. If the screen is frozen, perform a force restart as described earlier.
Will shutting down delete my data?
No, turning off your iPhone 15 does not delete any data. Powering down simply stops the device from running until you power it back on. Your apps, photos, and settings remain intact.
How long can I leave my iPhone powered off?
You can leave it powered off for days, weeks, or longer, as long as the battery remains charged. If the battery drains completely while off, you will need to charge it before the phone will boot again.
What is the difference between restart and shut down?
A restart reboots the device automatically, which can help resolve minor glitches. Shut down powers the device off completely until you manually turn it back on. Use shutdown when you want the phone off for travel, flying, or extended rest.
Summary
- Press and hold buttons, slide.
- Settings, General, Shut Down.
- Enable AssistiveTouch for on-screen control.
- Force restart if frozen.
Conclusion
Turning off an iPhone 15 is a small action that can solve many problems, from saving battery to resetting temporary glitches. The two main ways are using the physical buttons at the side of the phone or using the Settings app. Both methods end with the same slide to power off. If physical buttons fail, AssistiveTouch provides a virtual fallback that covers many functions though it may restart rather than fully shut down. When the device locks up, a force restart forces a reboot and often clears the issue.
Why does this matter? Powering down can reset network connections, stop background activity, and give your device a fresh start. It also helps when packing electronics for travel or troubleshooting persistent app issues. If you run into trouble, practice the Settings method once so you remember it when buttons are not convenient. Keep your iPhone charged before long shutdowns to avoid a dead battery the next time you need it. For more help, check Apple’s support pages or your device manual, and consider backing up important data to iCloud before major troubleshooting.
