Find Bluetooth Battery level on Windows 11/10
Monitoring the battery level of a Bluetooth-enabled device is not easy as most of these devices do not support Bluetooth battery monitor or battery level display. If some of them do, you have to install additional software to find it. Windows 11/10 eliminates this requirement. All you have to do is-
1] Add a Bluetooth device
The simplest, way of getting your Bluetooth device battery to display on your Windows 10 screen is to add a Bluetooth device. For this turn ‘on’ the Bluetooth mode of your device, go to Windows ‘Settings‘ > Devices > ‘Bluetooth & other devices’. Once there, click the ‘+’ button adjacent to ‘Add Bluetooth or other devices‘ and choose the kind of device you would like to add.
2] Connect the Bluetooth device
When the device becomes visible under ‘Add a device‘ screen, select it and hit the ‘Done‘ button.
Once connected, go back to ‘Bluetooth and other devices screen‘ and scroll down to ‘Mouse, Keyboard and Pen section‘.
Simply move the cursor alongside the connected device to display its battery level. You will see it in Windows 11 like this:
Please note that there are multiple ways via which you can show Bluetooth devices’ battery information. However, Windows 11/10 understands only one of them (Bluetooth Low Energy GATT Battery Service). As such, if your device is not a Bluetooth Low Energy device (like Apple’s Magic Mice/Keyboards/Trackpads, all of the headphones/headsets/speakers, and most of the game controllers), Windows 11/10 will fail to show their battery information. Even if your device is Bluetooth Low Energy device or if it uses a different protocol to report its battery information (like the example of Mi Band 2 in the screenshot), Windows will not display its battery level. I hope this helps!
