Ever since I updated to iOS 11, there is a persistent location services icon (arrow) in the status bar. It simply does not stop tracking me! It switches between being an outline and a filled in arrow, however. I have checked in settings, and it is "Significant Locations" that might be doing this. Every time I check, that arrow is purple, but I don't remember it always tracking my location in previous version of iOS. However, I would like to keep that on as I find it useful. I've tried turning that one off, and doesn't help too much anyway. I have location services off (from the start) for many apps that I don't need to share my location with, but this persistent icon is something new they've done in iOS 11 and I'm worried about my battery life on my 5s. I don't want to turn off location services completely as that would defeat the purpose of maps etc. Any ideas or reasons why they've done this?
