When this happens, battery usage suddenly drops. Restarting the phone sometimes makes face id works, when this happens, battery consumption returns to normal. I often have to do this several times a day.
iPhone 11, iOS 16
Hi coobal,
Thank you for using the Apple Support Communities! We see you were linked from the article "If Face ID isn't working on your iPhone or iPad Pro". Were you able to try all the steps listed? If so, are you receiving any specific error when this occurs? For example if you see "Face ID has been disabled", then you'll want to follow the steps below:
If an alert says Face ID has been disabled on your iPhone or iPad Pro
1. Update your iPhone or iPad to the latest version of iOS or iPadOS.
2. Check if there is an issue with Face ID in your iPhone's parts and service history. To do this, open the Settings app, tap General, then tap About.
3. If you still can't enroll your face or unlock your device with Face ID, you can take your device to an Apple Store or Apple Authorized Service Provider, or contact Apple Support about your iPhone or your iPad.
Hope this helps!
Have a great day.
