iPhone Why is Compass Calibration constantly triggered and running?

[Benz63amg]

Under Privacy > System Services, I can see that Compass Calibration is constantly purple, should that be disabled ? Is it causing unnecessary battery drain

I've pretty much always had it disabled.

And your iPhone’s compass functions properly? ( such as when using maps)

Purple simply means the app has recently used location services.

As far as I can tell -- haven't had an issue where something didn't look/work right when I use maps or navigation.

What about the Motion Calibration setting under that same menu? You have that disabled too? That’s for the step counter I believe and workouts

I have that disabled as well, but I also don't use the step counter or those type of features.

Oh so you don’t use the health and fitness features of the phone and Apple Watch, I think that for proper performance of these features I should leave compass calibration and motion calibration enabled but then again I’m not certain if these settings affect these things which is why I created this thread

Question: mine is calibrated wrong. South is North. East is West. How do I recalibrate that?

Settings --> Compass --> toggle True North OFF.

Can anyone else chime in on this? I just watched a YouTube video explaining things to turn OFF in iOS 13 and they said that most of these things under privacy system services should be off including motion calibration and distance but isn’t that going to affect Apple Watch step counter and overall health fitness tracking?

I filed a bug report on this a few years ago. On the iPhone 6s or later, compass calibration relies on the M9 chip (or later) which is always-on. They said that since the hardware responsible is always on, it will not cause any additional battery drain.

how come that the compass orientation in google maps literally stops working when “compass calibration” is turned off then?

Ha thanks for that hint- I was always wondering why stupid google maps couldn’t show me where I was looking at - because I had that turned off.
since the 11 pro battery is so massive, I think I’ll turn it back on and observe.
