A new, community-developed Windows utility named "Halo Battery" aims to simplify the monitoring of wireless peripheral battery levels. Created by Reddit user headvox, this application consolidates the charge status of devices connected via 2.4 GHz or Bluetooth into a single, convenient tray interface, eliminating the need for multiple manufacturer-specific applications.
Halo Battery displays each connected device with its own taskbar icon. These icons feature a ring that visually represents the battery level, changing from green to amber and then red as the charge depletes. A subtle "breathing" green animation indicates when a device is actively charging. Hovering over an icon reveals the precise battery percentage.
Initial testing has confirmed compatibility with a range of devices, including the Razer BlackShark V2 Pro (2023), WLmouse Beast X Max, GameSir G7 Pro, 1MORE SonoFlow headphones, and the Logitech G502 X Plus. A growing list of successfully tested devices is being maintained on the project's GitHub page. The utility's primary benefit lies in its ergonomic advantage, providing an at-a-glance overview of all wireless kit battery health, and crucially, reducing the reliance on potentially resource-intensive manufacturer bloatware. For example, users can track their Razer mouse battery without needing to install the Synapse application, which has been noted to consume significant background memory.
The development of Halo Battery highlights a perceived gap in Windows' native functionality. As one Reddit user commented, "It's pathetic that a feature which should just exist as standard has to be implemented by a hobbyist." Currently, Windows only displays battery information for some Bluetooth devices within the Settings app, and most 2.4 GHz dongle devices do not report their battery status to the operating system at all, necessitating proprietary software. Halo Battery addresses this by offering a unified solution.
While the utility has been well-received, community suggestions for improvement include displaying the exact percentage on each icon without requiring a hover, and implementing custom audio alerts for low battery levels. Headvox also noted that much of the application's code was generated with the assistance of Anthropic's Claude AI model, with the user providing the concept, testing, and design direction.
