+
+XBM is a small companion app for Windows that monitors the battery level of your gamepad and sends a notification when it's low. It's designed to work with the Xbox controller, but supports any gamepad that uses the XInput API. Basically it fulfills the job that the Xbox Accessories app should have done.
