The proximity sensor in the iPhone uses infrared light, which comes from the top of the screen. Imagine it’s like a tiny invisible flashlight that shines light and waits to see how long it takes for that light to bounce back. This helps the iPhone figure out how close something is to the screen.

When you’re on a call and you lift the phone to your ear, the sensor notices this because the light bounces back quicker. As a result, the screen turns off. This not only saves battery but also stops your cheek from accidentally touching the screen.
