Force Restart iPhone 15 Method
Apple has recently released four new models of the iPhone series: iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. Like all iPhones currently sold by Apple, with the exception of the iPhone SE 2, it has a "edgeless" display and lacks the physical Home button that the iPhone has used for years.
For modern iOS devices, you can take advantage of the volume buttons and side buttons to perform actions such as force restarts.
Before you begin
This tip applies to all iPhones in the iPhone 15 series: iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. This year marks the first time that an iPhone has adopted a USB-C port instead of a Lightning port, but that won't change much for the following process beyond the cable used to connect the Mac.
Before you start, it's a good idea to familiarize yourself with the physical buttons on your iPhone. The two volume buttons are on the left side of your iPhone 15, while the side buttons are on the right. This experience doesn't use the iPhone 15 Pro's action buttons.
How to power off iPhone 15s
There are several ways to power off your iPhone 15 series. The quickest way to power off your iPhone 15 is to long-press the side button and either volume button at the same time until the Sliding off slider appears. Once it appears, simply slide your finger to power off your iPhone 15.
Another way to turn off your iPhone 15 is to go to Settings → General and scroll down to the bottom of the page. Once there, you will see a "Close" button. Tap "Power off" and then use the slider shown at the top of the screen to power off.
How to Power on iPhone 15
Long press the side button on your iPhone 15 until the Apple logo appears. If the screen remains black after pressing the side button for an extended period of time, your iPhone's battery may be drained, or (though unlikely) your iPhone may be in DFU mode.
How to Force Restart iPhone 15
If your device hangs or behaves abnormally, executing the following commands in quick succession will force restart your iPhone 15.
Step 1: Quickly press the Volume Up button and release.
Step 2: Quickly press the volume down button and release.
Step 3: Press and hold the side button until the iPhone 15 display turns black.
If successful, the iPhone 15 will reboot and the Apple logo will appear. After some time, the phone should reboot and return to the iOS lock screen.

How to temporarily disable Face ID on iPhone 15
To temporarily disable Face ID, press and hold the side button and either volume button at the same time until the slide off slider appears. To reactivate Face ID, you need to unlock your iPhone 15 with your device passcode.
Use Emergency SOS on iPhone 15
Triggering an emergency SOS will contact emergency services. Use this feature only in the event of a real emergency. You don't need to take your iPhone 15 out of your pocket to enable Emergency SOS alone.
There are three ways to trigger Emergency SOS on your iPhone 15:
- Press and hold the side button and one of the volume buttons at the same time until Emergency SOS is triggered.
- Long press one of the side buttons and the volume button at the same time until the slide off slider is displayed. Use the Emergency SOS slider to activate Emergency SOS.
- Visit Settings → Emergency SOS, then enable the Call with side button switch. This feature allows you to trigger Emergency SOS by pressing the side button 5 times in quick succession.
There's also a quiet call option in Set Up → Emergency SOS. Enabling this feature will mute warning alerts, flashing, and voice audio for more discrete triggering options.
Finally, there's the collision detection switch, which automatically calls emergency services if your iPhone detects that you've been in a car accident.
How to Disable Find My when iPhone 15 Turns Off
iOS includes a feature that allows your iPhone 15 to continue to be tracked through Find My even when it's turned off. To use this feature, you need to sign your iPhone 15 into the Find My network and enable location services.
To disable the Find My feature when your iPhone 15 is powered off, do the following:
Step 1: Long press the side button and either volume button at the same time until the slide off slider appears.
Step 2: Click on the "Find iPhone after Power Off" message.
Step 3: Click the "Turn off Find Temporarily" button in the dialog box, and enter your device passcode.
Step 4: Use the Slide Off slider to turn off the Find disabled iPhone 15 power.
