What is BatteryOnPC?

BatteryOnPC is a lightweight utility for Windows 10 and 11 that reads the battery level of your wireless devices and shows it permanently in the taskbar. It covers PlayStation controllers (including the PS5 DualSense, which Windows cannot read on its own) Xbox controllers, Bluetooth gamepads, gaming mice, keyboards and headsets.

It runs in the background, uses no measurable CPU, adds no input lag in game, and sends a Windows notification as soon as a device drops below the threshold you choose. One-time purchase, no subscription, no account needed to use it.
