Getting Battery Status In Windows 10

The Battery Class provides information about a battery controller that is currently connected to the device,

Step 1: Open a blank app and add a Button and a TextBlock either from the toolbox or by copying the following XAML code into your grid.

<StackPanel>
    <TextBlock Text="Battery Status" Margin="10" FontSize="20"></TextBlock>
    <StackPanel Margin="10,20,0,0">
        <Button Name="getBatteryStatus" Height="40" Width="140" Content="Get Battery Status" Click="getBatteryStatus_Click"></Button>
        <TextBlock Name="batteryStatus" Margin="10,20,0,0" Height="50" FontSize="20"></TextBlock>
    </StackPanel>
</StackPanel>

  

Step 2: Add the following namespaces to your project which is needed in further C# code.

using Windows.Devices.Enumeration;
using Windows.Devices.Power;

Step 3: Copy and paste the following code to the cs page which will be called on button click event and the battery status in the TextBlock.

private async void getBatteryStatus_Click(object sender, RoutedEventArgs e)
{
    var deviceInfo = await DeviceInformation.FindAllAsync(Battery.GetDeviceSelector());
    foreach (DeviceInformation device in deviceInfo)
    {
        var battery = await Battery.FromIdAsync(device.Id);
        var report = battery.GetReport();

        double maximum = Convert.ToDouble(report.FullChargeCapacityInMilliwattHours);
        double remaining = Convert.ToDouble(report.RemainingCapacityInMilliwattHours);
        double percentage = ((remaining / maximum) * 100);
        int per = Convert.ToInt32(percentage);

        batteryStatus.Text = "You have " + per.ToString() + "% battery remaining" ;
    }
}

Here we are calculating the percentage by using the FullChargeCapacity and RemainingCapacity values.

Step 4: Run your application and test yourself.
