How to Turn Off an iPhone Without the Power Button
Your iPhone Power Button (also known as Sleep / Wake Button) is busted and you want to turn the iPhone off, or at least lock the screen. Unless you fix the button, you’ll have to use a workaround to turn off your iPhone without using the Power Button.
Luckily, there are ways around using the hardware button, buried in the settings of your phone. This guide will show you how to lock or even shut down an iPhone without using the Power Button.
Shutting down or rebooting your iPhone is rarely necessary, but can be required to fix intermittent issues with your networking and apps. Usually, you would press and hold the Sleep / Wake Button until the “Slide to Power Off” slider would appear. This is of course hard to do with a busted Power Button.
Accessing “Slide to Power Off” without the button
Open up your “Settings” app, go to “General” and view the “Accessibility” menu. Select the “AssistiveTouch” feature, which is present in all modern versions of iOS. AssistiveTouch is there for ergonomic reasons. It allows disabled individuals with a limited range of motion to fully control their devices without having to use the physical keys. Enable AssistiveTouch to continue.
You’ll notice a small circular shape appear, usually on the right hand side of your screen. By tapping the dot, we can access the menu options of AssistiveTouch. The feature can simulate a press of the Home Button and even lock the screen if you press “Device” and then “Lock Screen”. By pressing and holding the “Lock Screen” option, we can even “Slide to Power Off”. There you go, now you can use your iPhone to the full extent without replacing the broken Power Button.
Important: Note that you may require a USB cable and a power adaptor or computer to switch the iPhone back on after shutting it down. This might sound like a hassle, but you’ll get used to it pretty quickly. After doing this a couple of times, the procedure will become second nature to you.
