Remarks

The Battery API provides the way to get the current battery capacity value (Percent), the battery state, and the charging state. It also provides the events for an application to receive the battery status change events from the device. To receive the battery event, the application should register with the respective EventHandler.

public static async Task BatteryEventHandler()
{
    EventHandler<BatteryChargingStateChangedEventArgs> handler = null;
    handler = (object sender, BatteryChargingStateChangedEventArgs args) =>
    {
         Console.WriteLine("battery Level is: {0}", args.IsCharging);
    }
    Battery.ChargingStateChanged += handler;
    await Task.Delay(20000);
}

LevelChanged

LevelChanged is triggered when the battery level is changed.

{
    EventHandler<BatteryLevelChangedEventArgs> handler = null;
    handler = (object sender, BatteryLevelChangedEventArgs args) =>
    {
         Console.WriteLine("battery Level is: {0}", args.Level);
    }
    Battery.LevelChanged += handler;
    await Task.Delay(20000);
}
