Reddit User Launches Halo Battery Tray Utility for Windows
A Reddit user released Halo Battery, a Windows tray utility that consolidates battery levels of wireless devices into one place on the taskbar.
A Reddit user named headvox has released a Windows tray utility called Halo Battery that consolidates the battery charge status of devices connected via 2.4 GHz or Bluetooth into one place on the taskbar. The tool was built with the help of Anthropic's Claude AI model, with most code written by Claude.
Each device gets its own tray icon with a ring showing battery level and a device pictogram. The ring changes color: amber, then red when low, and breathes green while charging. Hovering over an icon shows the exact battery percentage.
Halo Battery has been tested with devices including Razer BlackShark V2 Pro (2023), WLmouse Beast X Max, GameSir G7 Pro, 1MORE SonoFlow headphones, and Logitech G502 X Plus. A growing list of tested devices is available on Halo Battery's GitHub page.
In October 2025, headvox stated that Windows shows battery for some Bluetooth devices only in Settings, not in the tray, and most 2.4 GHz dongle devices don't report battery to Windows at all, requiring vendor apps. Many accounts also note that Razer's Synapse app has a background service memory footprint of about 800 MB.
