Hi Philippe, As far as I can tell, the problem is that CLLocationManager class does not have any API to control update frequency. It allows to adjust the desired accuracy instead, which is hardcoded to kCLLocationAccuracyBest for now [0]. There is a https://bugreports.qt.io/browse/QTBUG-93860 which suggests providing ways to control this parameter via public API in Qt.

I want to use a longer interval when in background, in order not to drain the battery. But even in foreground I cannot change the frequency of position updates. Is it a bug or I am missing some subtleties? Using qt 5.15.2 and iOS 14.
