After upgrade the SDK from 7.2.1 to 7.3.0, I found that playing animation consumes much more battery. After debug I found the when playing AnimationLayer, onUpdate() is called for dozens of times in one second. In SDK 7.2.1 onUpdate() is called only once a second. onUpdate() will draw the screen and is heavy. It's called for so many times and will consume too much battery.
This is the test code copied from Garmin example in SDK: AnimationWatchFace. Nothing is changed except adding the following println() for debug::
//! Update the view
//! @param dc Device Context
public function onUpdate(dc as Dc) as Void {
// Update the entire draw layer
var clockTime = System.getClockTime();
var seconds = clockTime.hour*3600 + clockTime.min*60 + clockTime.sec;
System.println("seconds: " + seconds);
updateWatchOverlay(true);
}
I tested fenix7 on the simulator and this is the test result, Can somebody help on it? Is it expected or a bug? Thanks.
