About AirBattery
AirBattery shows battery levels for connected devices on a Mac in the Dock, menu bar, or widgets. It automatically searches for supported devices, can show battery information for other Macs and their peripherals on the same local network using Nearcast, and allows hiding devices and using a real-time battery menu bar icon.
It requires macOS 11.0 and later. iPhone or iPad devices must have trusted the Mac and paired once by cable while AirBattery is running, then remain on the same local network. Watch battery reading requires its paired iPhone to be detected over Wi-Fi or USB, and Bluetooth-based cellular detection supports only iPhone or cellular iPad.
