Stop Using Siri
If you’ve set up Siri, you know that Siri is constantly available just by saying the words “Hey Siri.” While this is super useful, having your iPhone always listening for the Siri call-phrase won’t help your battery life.
To Disable “Hey Siri,” you need to do the following:
- Open the Settings app.
- Scroll down and select Siri & Search.
- Toggle Listen for “Hey Siri” off.
