Control your devices’ batteries
Keep track of your device’s battery life from the most convenient spots on your Mac. Once you connect your iPhone, iPad, or AirPods, they will appear in the “Batteries” widget in the Today View. You’ll also be able to monitor batteries from the menu bar or Touch Bar.
Apart from your beloved Apple devices, you can keep track of the batteries of any Bluetooth headphones. Once you connect your device, enable “Show this device when on Wi-Fi” in Finder (Catalina or later), or Wi-Fi sync in iTunes (Mojave). As long as you stay on the same network, the battery level will be visible on Mac.
Whenever any of the connected devices run low on battery, the app will send you a notification so that you have time to recharge. Remember the last time you freaked out when your battery died after leaving home or office? Well, never again.
