Magic Battery

Magic Battery by Dloper

Choose up to four Bluetooth accessories per Stream Deck key, then press to see all their battery levels in one macOS notification. Designed for Apple Magic Mouse, Magic Keyboard and Magic Trackpad. Device selectors appear progressively as you add accessories, and the key refreshes its percentages every minute.

Requires macOS 13 or later and Stream Deck 7.6 or later. Supports Apple Silicon and Intel Macs. Only accessories whose battery levels macOS exposes are available; support for AirPods or every Bluetooth product is not guaranteed. macOS notification permissions and Focus settings control banner delivery.

Battery Infobar: drag this action onto the Stream Deck Neo Infobar and choose up to four accessories. Device names and percentages refresh every minute. The Infobar is display-only; use a Device Battery Monitor key to send notifications. Its percentages are always shown, independently of the key display checkbox.

Language: the interface and notifications follow Stream Deck’s language automatically. Translations are included for English, Simplified and Traditional Chinese, French, German, Japanese, Korean, Portuguese and Spanish. Unsupported languages use English. Device names are preserved. Portuguese is ready for hosts that provide a Portuguese language setting; the language choices available in Stream Deck are controlled by Elgato. macOS permission dialogs use the Mac’s system language.
