Rob Griffiths @rgriff:
One downside to golfing with a no-service iPhone: GPS acquisition takes a _long_ time. If phone powers down, you wait and wait and wait…

@rgriff Supposed to take 1-2 minutes. Are you sure you’re under low Earth orbit?

Rob Griffiths @rgriff:
@jeffporten 1-2 minutes is a lot—especially as it seems to take that long every time the phone powers down. With cell, it’s a few seconds.

@rgriff There’s a hardware mechanism to make subsequent locations faster, but I have no idea how that interacts with iOS power saving.
