How to Activate Siri on the iPhone

You can make sure Hey Siri is on by opening the Settings app, selecting Siri, and toggling on Hey Siri. Just remember that Hey Siri won't activate if you have Low Power mode on; so if it's not working, that's probably why. In those moments, simply click and hold the Side button to talk to Siri.
