AirPlay is a proprietary wireless communication protocol developed by Apple Inc. that allows users to stream audio, video, and other content from an iOS device, Mac computer, or Apple TV to another device that supports AirPlay, such as an Apple TV, HomePod, or AirPlay-enabled speaker.
AirPlay is a convenient way to share content with others, but there may be times when you need to turn it off. For example, you may want to turn off AirPlay if you’re not using it and want to conserve battery life, or if you’re having trouble connecting to an AirPlay device.
