4. Show battery percentage
iOS doesn’t display the battery percentage by default, but you could go into the Settings app and turn it on. On the iPhone X, the setting’s been removed. But have no fear. You can still see the battery percentage by swiping down on the right side of the notch. It’s now incorporated into the Control Center.
5. How to disable Face ID in an instant
If for whatever reason you find yourself in a situation where you don’t want Face ID to be your primary form of security — like if you’re being held captive somewhere and someone has your phone and could force you to look at it — you can quickly deactivate it.
Quickly press the power button (officially called the “Side Button”) five times and it’ll automatically turn Face ID off and default to your passcode to unlock. Entering your passcode will re-activate Face ID.
