How to make onPowerBudgetExceeded fire

Hi,

Actually, the question is in the title - how to make onPowerBudgetExceeded fire?
I am using a simulator with Fenix 5x, and in the onPartialUpdate() call I write code that takes longer than 30ms (I measure the execution time through System.getTimer() and get the execution time over 100ms). I see that the simulator is in low power mode and only onPartialUpdate() is called. But the onPowerBudgetExceeded event in the delegate class doesn't fire (in getInitialView() I create a delegate class, as shown in the Analog example from the SDK). What could be the reason why onPowerBudgetExceeded is not being called?

For the delegate to be called, you must be in low power, and you must run at least a minute - it's the avg from 00-59 seconds.

Do something like this in getInitialView. Include the delegate gfor the view.

    function getInitialView() {
		if( Toybox.WatchUi.WatchFace has :onPartialUpdate ) {  
        	return [ new SimpleView(), new SimpleDelegate()  ];
        } else {
        	return [new SimpleView() ];
        } 
    }

With a delegate like

class SimpleDelegate extends Ui.WatchFaceDelegate
{

	function initialize() {
		WatchFaceDelegate.initialize();	
	}
	
    function onPowerBudgetExceeded(powerInfo) {
        Sys.println( "Average execution time: " + powerInfo.executionTimeAverage );
        Sys.println( "Allowed execution time: " + powerInfo.executionTimeLimit );
        do1hz=false;
    }
}

This is exactly the code I am using, copied directly from the Analog sample from SDK. It seems that I did everything right, I want to understand why the onPowerBudgetExceeded event does not start.

Once you exceed the power budget (30 ms avg) onPartiialUpdate is never called. Are you sure you are exceeding the average?

Thanks. You are absolutely right - for the event trigger to work, you need to wait at least 1 minute.
