iOS 16.2 - Location Services

Not sure if anyone else has noticed this but for me - Location services are going crazy. I have the "Display location tracking" option enable as I like to know when an app is using my location. Since 16.2 yesterday, the system services have been firing location services every time I unlock my phone and then every minute or two after that. Doesn't matter which apps I open but "Compass calibration", "Find my iPhone", "Motion Calibration & Distance", "Networking & Wireless" and "Significant Locations" all seem to be firing up location tracking every couple of minutes in the background. I've never seen it this persistent before. I've even closed off all my apps and restarted (cos - y'know - turning it off and on again is just a standard thing to try) and it's still doing it. Anyone else noticed this?
