Properties
DeviceSpecificConversionFactor DeviceSpecificConversionFactor DeviceSpecificConversionFactor DeviceSpecificConversionFactor
Gets the device-specific conversion factor used to convert energy usage (mW) to a normalized percentage.
Important
These APIs consume significant CPU resources. We recommend using these APIs only for debugging purposes.
public : static double DeviceSpecificConversionFactor { get; }public static double DeviceSpecificConversionFactor { get; }Public Static ReadOnly Property DeviceSpecificConversionFactor As double// You can use this property in JavaScript.
- Value
- double double double double
The device-specific conversion factor used to convert energy usage (mW) to a normalized percentage
Remarks
To determine the estimated energy usage for the device in units of milliwatts (mW), divide the computed total energy usage by the DeviceSpecificConversionFactor.
Methods
ComputeTotalEnergyUsage() ComputeTotalEnergyUsage() ComputeTotalEnergyUsage() ComputeTotalEnergyUsage()
Computes the total cumulative energy usage of the foreground app since the last reset, expressed as a percentage of normal.
Important
This method consumes significant CPU resources. We recommend using this method only for debugging purposes.
public : static ulong ComputeTotalEnergyUsage()public static ulong ComputeTotalEnergyUsage()Public Static Function ComputeTotalEnergyUsage() As ulong// You can use this method in JavaScript.
The total cumulative energy usage of the foreground app since the last reset, expressed as a percentage of normal.
Remarks
Important
This method consumes significant CPU resources. We recommend using this method only for debugging purposes.
Reset the energy usage total by calling ResetTotalEnergyUsage.
The energy usage of a foreground app is classified into one these predefined levels, from lowest to highest energy consumption: LowUsageLevel, NearMaxAcceptableUsageLevel, MaxAcceptableUsageLevel, or ExcessiveUsageLevel.
ResetTotalEnergyUsage() ResetTotalEnergyUsage() ResetTotalEnergyUsage() ResetTotalEnergyUsage()
Clears the value that represents the total cumulative energy usage of the foreground app since the last reset.
Important
These APIs consume significant CPU resources. We recommend using these APIs only for debugging purposes.
public : static void ResetTotalEnergyUsage()public static void ResetTotalEnergyUsage()Public Static Function ResetTotalEnergyUsage() As void// You can use this method in JavaScript.
Remarks
This method doesn't reduce energy consumption, it simply resets the counter used to track total energy usage.
