Go to Settings and choose the Accessibility option
Once you are in the Accessibility tab, choose the Voice Control option.
Voice Control by default is off, just switch it on.
Follow the on-screen commands and set up Voice Control.
Once Voice Control is set up, you have a set of commands that are on by default. You can customise them if you want.
Simply say “Reboot Device” and a prompt will appear asking if you are sure about restarting it.
Your iPhone will now automatically restart.
Things to keep in mind
This feature works without giving Siri, Apple’s voice-assistant any command. If you want to use Siri, then there’s an option to do that as well. You can simply say, “Hey Siri, activate voice control” and get it activated.
Once Voice Control is activated, you will see a small blue mic sign in the status bar. You can turn that off by either telling Siri or going to the Accessibility option and disabling it.
So, just follow these simple steps and you’ll have the easiest way of restarting your iPhone.
