Location services Always on or when in use?
I have an iPhone 5S running OS 8.3.1
Trying to learn as much about using Siri and the services as I can to be able to maximize my use. What I ultimately want to know is. How does Siri know where I am if the location service is set to, "when in use" for maps, and for find my friends, instead of always?
This came about when setting reminders up for, "remind me when I leave home to take out dog." for instance, or "remind me when I get to Hy-Vee to get Dr. Pepper". If the map is not always on, how does Siri know where I am? Is this going to fail? or not work? Do I need to leave the map on all the time?
Thanks
