Bluetooth Battery Monitor

Bluetooth Battery Monitor is a Windows application that displays the actual battery level of Bluetooth devices such as headphones, mice, and keyboards. Unlike system estimations, the tool reads data measured by each device and alerts the user when charging is needed, showing all information in a unified dialog box.

• Accurate battery reading. The application shows real battery data measured by the Bluetooth device hardware, avoiding inaccurate operating system estimates. This information updates periodically to reflect the actual consumption of each connected peripheral.
• Devices overview. All compatible devices are displayed in a single compact window, allowing the user to check the battery status of headphones, mice, and keyboards at a glance without opening multiple configuration panels.
• Low battery alerts. The program sends a visual notification when any device battery level drops below the configured threshold. The system tray icon changes color to indicate the overall status without interrupting workflow.
• Vendor-specific protocol support. Beyond standard Bluetooth, the application supports devices using proprietary protocols, including AirPods (1st, 2nd generation and Pro), Apple Magic Mouse/Keyboard, Logitech peripherals (Unifying/Nano/Lightspeed), and wireless gaming devices from Razer, HyperX, Corsair, and SteelSeries.
• TWS detailed information. For true wireless headphones that support it, the interface shows individual battery levels for each earpiece and the charging case separately, providing precise status control of each component.
• Configurable notification threshold. The user can define the exact percentage at which to receive alerts, adapting the application to different device types and usage patterns to avoid unexpected battery depletion.
• System tray indicator. The tray icon reflects the lowest battery level among all connected devices through a color code, providing continuous status information without opening the main window.
• Non-Bluetooth device support. The application extends compatibility to certain wireless devices that do not use Bluetooth, such as proprietary receivers from major brands, provided these devices report their battery status.
• Anonymous data collection. The application collects anonymous usage data to improve compatibility and development, with prior notification during installation and the option to review details in the settings window.
• Version history documentation. The program includes a detailed version history documenting new compatible devices added in each update, allowing users to verify support for their specific hardware.

The development history of Bluetooth Battery Monitor began with the need to solve a common problem: the lack of reliable battery information for wireless devices on Windows. The developer, operating under the name BluetoothGoodies, released the first versions of the tool to provide real readings based on hardware data rather than system estimations. The application is primarily written in C#, leveraging the .NET framework to interact with the Windows Bluetooth stack and manufacturer-specific protocols. Since its creation, the project has continuously evolved, adding support for devices with proprietary protocols from Apple and Logitech, and expanding to gaming peripherals from brands like Razer and Corsair.
