onPowerChanged

onPowerChanged Event. Is raised when the devices power source is changed; the device is plugged-in to mains power for example. It is also raised when the battery level changes. To subscribe to the event use: airlock.device.onPowerChanged.addListener(function (powerInfo) {}) To unsubscribe to the event use: airlock.device.onPowerChanged.removeListener(afunctionReference)
Type:
Source:
Example
// Subscribe to event
airlock.device.onPowerChanged.addListener(handlePowerChanged);

function handlePowerChanged(args) {
		if (args.powerSource === airlock.device.PowerSource.BATTERY) {
			// Using battery. Display remaining battery percentage.
			alert(args.remainingBatteryPercent)
		}
}

// Unsubscribe
