Bluetooth Device Battery Indicator Display in System Tray

Question

When we hover a mouse over the Volume icon in System Tray it currently shows the sound level indicator. Would it be possible to replace with Battery Level indicator (if connected to BlueTooth device) or add it along with Sound Level?

Answer 1

Hello,

I have written a PowerShell script to obtain the battery level of my headphone.
If anyone wants to use it, just remember to follow the instruction on the comments and change the name of your Bluetooth device on variable 'BTDeviceFriendlyName' to the same name that appears assigned to your Bluetooth device.

The battery level will appear in a windows pop-up dialog. Just read the instruction in the beginning of the script.

The script also measures the time it takes to execute. I was a bit worried about the time it was taking to execute, so after tweaking and optimizing a little bit, I left it there for the next brave person that can find a way to make it faster ;-)

BTW, I have only tested with Windows 11, so you may have to adapt or change the value of '$Device.InstanceId' to the correct one according to your system.

Cheers!

# ATTENTION: Don't forget to allow the powershell script to run first.
# Here is a step by step of how to execute this script:
# - Open a Powershell command prompt. 
# - Allow shel script execution with command:
#   Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process
# - Execute the current powershell script with the command:
#   .\GetBatteryLevel_DOQAUS-CARE1v1.ps1
# - The results may take some time to come. A pop-up will show on your 
#   main screen. You must click 'Ok' to unblock the Powershell command prompt.

$StartTime = Get-Date
$BTDeviceFriendlyName = "DOQAUS CARE 1"
$Shell = New-Object -ComObject "WScript.Shell"
$BTHDevices = Get-PnpDevice -FriendlyName "*$($BTDeviceFriendlyName)*"

if ($BTHDevices) {
    $BatteryLevels = foreach ($Device in $BTHDevices) {
        $BatteryProperty = Get-PnpDeviceProperty -InstanceId $Device.InstanceId -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' |
            Where-Object { $_.Type -ne 'Empty' } |
            Select-Object -ExpandProperty Data

        if ($BatteryProperty) {
            $BatteryProperty
        }
    }

    if ($BatteryLevels) {
		$ElapsedTime = (Get-Date) - $StartTime
        $ElapsedTimeMilliseconds = [math]::Round($ElapsedTime.TotalMilliseconds, 0)
        $ElapsedTimeStr = "$($ElapsedTimeMilliseconds) ms"
        if ($ElapsedTimeMilliseconds -gt 1000) {
            $ElapsedTimeSeconds = $ElapsedTime.TotalSeconds
            $ElapsedTimeStr = "$($ElapsedTimeSeconds) sec"
        }
        $Message = "Battery Level of $($BTDeviceFriendlyName): $BatteryLevels %`nElapsed Time: $($ElapsedTimeStr)"
        $Button = $Shell.Popup($Message, 0, "Battery Level", 0)
    }
    else {
        Write-Host "No battery level information found for $($BTDeviceFriendlyName) devices."
    }
}
else {
    Write-Host "Bluetooth device found."
}

I am using this tool: https://workstation-master.com/bluetooth-battery-level.html simple and looks like part of the system, check it

Hello there,

So you need the battery level of your Bluetooth device right? We cannot get the Battery percentage by hovering but you can get it when you see the connected list.

1 Open Settings (Win+I). 2 Click/tap on Bluetooth & devices on the left side, and click/tap on Devices on the right side. 3 Look for the battery percentage (if supported ) of your Bluetooth device(s) on the right side.

You can get information on Bluetooth devices using the Get-PnpDevice cmdlet. This should return a list of PnP Devices, their Status, Class, FriendlyName and InstanceID.

Get-PnpDevice You can filter the results with -Class parameter. To specify Bluetooth PnP devices, you can enter "Bluetooth" as a string value for the -Class parameter.

Get-PnpDevice -Class 'Bluetooth'

Hope this resolves your Query !!
