A more informative Mac battery indicator
BatteryBoi is an open-source replacement for the standard macOS menu bar battery indicator. The project began with a simple goal: show estimated time remaining in hours and minutes instead of relying only on a small icon or percentage. Its scope later expanded into a fuller battery utility with notifications, usage insights, and visibility into supported Bluetooth devices.
Information that stays close to the menu bar
The official repository describes a compact workflow built around the status bar rather than a separate dashboard:
- See estimated battery time when macOS makes that value available, with percentage as the fallback.
- View battery levels for connected Bluetooth devices that expose the information through System Information.
- Use the app on Intel and Apple silicon Macs across the supported macOS releases.
- Restore Apple's original battery indicator at any time from Control Center settings.
- Install a released DMG manually or use the documented Homebrew route.
Open development and clear boundaries
BatteryBoi's source, releases, issue tracker, and GPL-3.0 license are public. The repository also documents localization contributed by its community and explains its limited install analytics: architecture, macOS version, locale, and theme, rather than personal information. That makes BatteryBoi most relevant to people who want a more expressive menu bar readout while retaining the ability to inspect the implementation and follow development in the open.
