Bluetooth Battery Level Indicator
Real-Time Peripheral Battery Status & Telemetry Tray Utility
Ultra-lightweight system tray utility and desktop monitor that displays live battery percentages, discharge telemetry, and smart low-power alerts for all connected Bluetooth devices.
Live System Workspaces
Engineered for High-Consequence Operations
Never be blindsided by a dead wireless mouse, keyboard, gaming controller, or headset in the middle of a critical presentation or gaming session. Bluetooth Battery Level Indicator provides real-time, zero-latency battery telemetry right in your Windows / macOS system tray or dock. While operating systems often bury peripheral battery levels deep inside Settings panels, Bluetooth Battery Level Indicator exposes them at a single glance with customizable low-battery chimes, dual-channel audio telemetry (e.g. left and right AirPods + charging case), discharge rate predictions, and hardware auto-sleep commands to extend device lifespan.

Finally, an app that shows AirPods case battery properly on Windows!
Windows 11 usually only shows a combined headphone battery or none at all. This utility shows left bud, right bud, and case percentages cleanly in the tray. Worth every single penny.
Lightweight, no bloatware, just works
It uses practically zero RAM and doesn't bug you with ads or unnecessary cloud logins. Set it once, and your tray always shows your mouse and keyboard levels. Beautiful Swiss design too.
Great notifications before meetings
Saved me from having my headset die mid-client pitch multiple times. The audio chime when battery hits 15% gives me enough warning to plug in the USB-C cable.
