The iPhone 18 Pro and iPhone 18 Pro Max don’t have a traditional power button. You can shut them down using the Side and Volume buttons, from Settings or Control Center, or simply ask Siri to turn off your iPhone.
If you’re new to the iPhone 18 Pro, here’s how to power it off using any of these methods.
How to Power Off iPhone 18 Pro or 18 Pro Max
The quickest way to shut down your iPhone 18 Pro or 18 Pro Max is by using its physical buttons.
- Press and hold the Side button and either the Volume Up or Volume Down button at the same time.

- Keep holding until the power-off screen appears.
- Drag the slide to power off slider to the right.

- Wait a few seconds for the screen to go completely black.
Your iPhone is now turned off.
To turn it back on, press and hold the Side button until the Apple logo appears.
Note: A quick press of the Side button only locks the iPhone and turns off the display. It does not shut down the device.

Your iPhone 18 Pro or 18 Pro Max will then shut down.
Using Siri (Without Touching the Screen)
You can also ask Siri to shut down your iPhone without using any buttons or touching the screen. This can be particularly useful if the display is damaged or the touchscreen isn’t responding.
- Activate Siri by saying “Hey Siri” or long-pressing the Side button.
- Say “Turn off my iPhone” or “Shut down my iPhone.”
- Siri will ask you to confirm the action.
- Say “Yes” to confirm.

Your iPhone will then power off without requiring you to swipe the Power Off slider.

What If Your iPhone 18 Pro Is Frozen or Not Responding?
If the touchscreen isn’t responding, you can try using the Siri method above to shut down the iPhone without touching the screen.
If your iPhone is completely unresponsive, you’ll need to force restart it instead. This doesn’t erase your photos, apps, or other data.
