Tizen.System.dll

The Battery class provides the properties and events for the device battery.

public static class Battery

Inheritance

object

Battery

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.

Properties

IsCharging

Gets the current charging state.

Declaration

public static bool IsCharging { get; }

Property Value

Type	Description
bool

Level

Gets the current battery level.

Declaration

public static BatteryLevelStatus Level { get; }

Property Value

Type	Description
BatteryLevelStatus

Percent

Gets the battery charge percentage.

Declaration

public static int Percent { get; }

Property Value

Type	Description
int	It returns an integer value from 0 to 100 that indicates the remaining battery charge as a percentage of the maximum level.

Events

ChargingStateChanged

ChargingStatusChanged is triggered when the battery charging status is changed. This event is triggered when the charger is connected/disconnected.

Declaration

public static event EventHandler<BatteryChargingStateChangedEventArgs> ChargingStateChanged

Event Type

Type	Description
EventHandler<BatteryChargingStateChangedEventArgs>

Examples

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.

Declaration

public static event EventHandler<BatteryLevelChangedEventArgs> LevelChanged

Event Type

Type	Description
EventHandler<BatteryLevelChangedEventArgs>

Examples

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

PercentChanged

CapacityChanged is triggered when the battery charge percentage is changed.

Declaration

public static event EventHandler<BatteryPercentChangedEventArgs> PercentChanged

Event Type

Type	Description
EventHandler<BatteryPercentChangedEventArgs>

Examples

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