Most of the Bluetooth devices come with their software to change default actions and provide information about the device’s battery status as well. For instance, I have installed Logitech SetPoint software to know the exact status and change default button actions of Performance MX mouse (MR0007), which I bought a few years ago (an excellent mouse at its price range).
The Logitech SetPoint even sends out a notification when the battery level is low, although there are indicators on the mouse to display approximate battery level. The same is the case with Bluetooth devices from other manufacturers as well.
The good thing is that you don’t need to open your mouse, keyboard or that Bluetooth device’s software to check its battery level when it’s connected to your Windows 10 PC.
If you have connected a Bluetooth mouse, keyboard, headphone or another device to your Windows 10 PC, you can now check the battery level of the external device with ease.
Windows 10 RS5 build 17639 and later builds show you the battery level of your external Bluetooth device. This means that, you get the exact battery level status of the external Bluetooth device.
Please note that Windows 10 can show the Bluetooth device’s battery level only if the device supports this feature. All devices might not support this feature.
Check the battery level of Bluetooth devices in Windows 10.
Step 1: Navigate to Settings app > Devices > Bluetooth & other devices.
Step 2: You should now see the battery level next to the device name.
Obviously, only devices that are currently connected to your PC will appear in the devices list.
If Windows 10 is not showing the battery level of the Bluetooth device, please check if you are running 17639 or above builds of Windows 10 RS5.
Also, update the device driver to the latest available version and check again. You can also contact the device manufacturer to check if it supports this new feature of Windows 10.
