I actually noticed this - iOS has this nice feature of giving warnings like "Uber has been tracking your location", which was a WTF moment for me because I haven't used Uber that day at all. So in response I've cut its location access completely. I've also had a similar experience with Waze. WTF are these apps doing with my location while I'm not using them? Btw, for all the badmouthing I've given Apple and iOS over the years, this is one feature of iOS that I like. But I would have preferred the option to force location tracking only while using the app.
