Important
- No Active Charging Status: The mouse hardware/firmware does not transmit a charging state flag over HID (the official driver app also lacks charging status detection).
- Paused Percentage Updates While Docked: When the mouse is placed on its charging dock, it stops sending battery percentage reports. Consequently, the app will continue to display the last percentage received right before charging started.
- Checking Updated Battery Percentage: If you need to check the updated battery percentage during or after charging, simply remove/lift the mouse off the dock. The app will receive and display the updated percentage.
- Verifying Full Charge: Because HID battery reports pause while docked, the only reliable way to confirm when the mouse is 100% charged while still on the dock is to check the physical LED indicator on the device.
