description: "macOS will tell you the battery state of an Apple keyboard but not your Logitech mouse, your AirPods clone, or your gamepad — Mac Juice Monitor fills the gap."
---

The macOS battery widget shows your AirPods and Magic Mouse but stays mute about every other Bluetooth peripheral: third-party keyboards, gamepads, headsets that report battery over the standard service but not Apple's private API. Mac Juice Monitor reads the public BLE battery characteristic and surfaces every connected device's percentage in the menu bar. Free, open-source, and tiny.
