Does disabling "App Refresh" in the Settings on iPhone (with iOS 9.3.4) actually stop an app from running in the background?
Because I actually disabled "App Refresh" for all apps (globally). And then I started the app Nike Running, and then after it started, then I started Pokemon Go.
So Pokemon Go should be the foreground app, and Nike Running should be the background app. However, when I stopped walking or continued to walk, the phone did vibrate with the Nike Running voice about the walk pausing and resuming. So it looks like Nike Running is running in the background despite the App Refresh being disabled?

Here's Apple's definition of Background App Refresh:
A key part of that definition is
...apps that take advantage of this feature...
. Perhaps Nike coded their app to take advantage of some of those features while continuing to run in the background (to update your exercise location, stats, etc).There's a good read for this on Background App Refresh in Layman's Terms and I would recommend you read it to get a better understanding on how the system is setup and how it's used by apps.
