Turning off an iPhone 15 is quick and simple. You can power it down using the hardware buttons, the Settings menu, or AssistiveTouch if your buttons do not work. Read the short steps below to learn each method and pick the one that fits your situation. In under a minute you can safely shut down your device and conserve battery or troubleshoot a problem.
Tutorial – How To Turn Off iPhone 15
This section shows three reliable ways to turn off an iPhone 15. Follow the button method for speed, the Settings method when buttons are hard to use, or AssistiveTouch when you need an on-screen option.
Step 1, Press and hold the side button and a volume button
Press and hold the side button and either the volume up or volume down button until the power off slider appears.
When you hold these two buttons together the Emergency SOS screen may appear if you keep holding, so release once the slider shows. Slide the power off slider to the right, and the phone will shut down fully. This is the fastest method for most people.
Step 2, Open Settings and choose Shut Down
Step 2, Open Settings, tap General, then scroll to the bottom and tap Shut Down to reveal the power off slider.
This method is useful when your buttons are unresponsive or you prefer not to press hardware keys. After tapping Shut Down, slide the power off slider to the right and wait for the screen to go black. The shutdown process takes a few seconds before the phone is fully powered off.
Step 3, Use AssistiveTouch to power off
Step 3, Enable AssistiveTouch in Accessibility, open the on-screen menu, go to Device, then tap More and select Restart or use the custom action to show the shut down option.
AssistiveTouch provides an on-screen button you can use when physical buttons fail or when you want a one-touch option. If your AssistiveTouch menu does not show Shut Down directly, you can create a shortcut or use the Restart option to achieve a similar result. Remember that Restart will turn the phone off and back on automatically.
After you complete any of these actions the iPhone 15 will power down and show a black screen. The device will not receive calls, notifications, or use battery while off. To turn it back on, press and hold the side button until the Apple logo appears.
How To Turn Off iPhone 15 Tips
- Use the Settings method if the side or volume buttons are stuck or damaged.
- If a slider does not appear, make sure you are holding the buttons long enough, but stop before Emergency SOS triggers.
- Enable AssistiveTouch ahead of time if you expect hardware trouble, so you have an easy on-screen option.
- Charge the phone a little before powering it down if you plan to keep it off for a long time, to avoid deep battery discharge.
- If the phone is frozen and will not respond, try a force restart to refresh the system, but note that this is not the same as a normal shutdown.
- Customize the Action Button on models that have it, to run a Shortcut that can simulate shutdown steps when needed.
- Keep your iOS updated, as software changes can affect how shutdown and restart options behave.
Frequently Asked Questions about How To Turn Off iPhone 15
Can Siri turn off my iPhone 15?
No, Siri cannot power off the iPhone. Siri can help open Settings for you or guide you through steps, but it cannot execute a shutdown command. You will need to use the hardware buttons, Settings, or AssistiveTouch.
What if the iPhone 15 is frozen and will not show the power off slider?
If the phone is frozen, perform a force restart by quickly pressing and releasing Volume Up, then Volume Down, then press and hold the side button until the Apple logo appears. This forces a reboot, which may resolve the freezing. It is not the same as powering off, but it often fixes unresponsive behavior.
Will turning off my iPhone 15 delete any data?
No, powering off your iPhone does not delete data. Shutdown simply stops the device from running. Your apps, photos, and settings remain intact and will be available when you power the phone back on.
How do I turn off my iPhone 15 if the side button is broken?
Use Settings, go to General, then tap Shut Down to access the power off slider. If the Settings app is not available or you prefer a different method, enable AssistiveTouch in Accessibility to use on-screen shutdown controls.
How long will my iPhone 15 battery last while turned off?
When the phone is completely powered off, battery drain is minimal, and the device can hold charge for weeks depending on battery health and storage charge level. If you leave it off for months, the battery can slowly lose charge. It is a good idea to check and charge the phone occasionally.
Summary
- Press side and volume button together
- Open Settings, General, Shut Down
- Use AssistiveTouch for on-screen shutdown
