Powering off an iPhone without touching the screen can be useful in situations where the screen is cracked or unresponsive, or if the user has difficulty using their hands. There are two main methods to power off an iPhone without touching the screen: using Siri or using AssistiveTouch.
To power off using Siri, simply say “Hey Siri, turn off my phone.” Siri will then ask for confirmation, and once confirmed, will power off the device. To power off using AssistiveTouch, first enable AssistiveTouch in the Accessibility settings. Once enabled, a small grey circle will appear on the screen. Tap on the circle, then tap on the “Device” option, then tap on the “More” option, and finally tap on the “Restart” option.
