How Adaptive Brightness Works on Phones and Laptops

Modern phones and many laptops can change screen brightness automatically as lighting conditions change. Walk from a dim room into bright daylight and the display may become brighter; return indoors and it may gradually dim again. This feature is commonly called adaptive brightness, automatic brightness, or a similar name. It can make a display easier to see while reducing unnecessary power use, but it does not simply choose one fixed brightness for every room.
