The reason for turning on the status bar icon is so you can tell when your iPhone is using GPS (location) services. If the little arrow (pointing NE) is on the status bar, your phone is using location services. If you see that icon frequently, something is running that you may want to turn off.
Oh... well, I have it OFF under SYSTEM SERVICES but I still see the little arrow to let me know about LOCATION SERVICES such as weather.
So I go to Settings > Location services.
On this page, I have several of these turned ON so that they're available if I need them. I only see a little grey arrow next to weather since it's been used within the last 24 hours. The others (waze and trailhead) have nothing next to them indicating that they haven't been used lately.
On this alone, when I access weather, I see the arrow appear in the task bar.
If I go to Settings > Location Services > System Services I have everything off. So no "cell network search", "compass calibration", "diagnostic & usage", etc...
But I also have the "status bar icon" off. (just turned it on for kicks). Even with it OFF I still see the icon in the status bar when Weather, Waze, or Trailhead access my location. I was under the impression that the Status bar icon option only controled "cell network search", "compass calibration", "diagnostic & usage", etc. Therefore, if those are all off, it wouldn't make sense (or matter) to have "status bar icon" on.
am I misunderstanding?
