What is the orange light on my iphone?

The orange light on your iPhone is most likely the LED light located near the front-facing camera. This light is used for functions such as indicating low battery, charging status, or notifications from apps. When the light is orange, it could indicate that your phone is charging, or you have a notification waiting for you. You can check your notifications by unlocking your iPhone and swiping down from the top of the screen to see any pending alerts.
