When I go out for a walk or run, my mileage and exercise time is always much shorter than it should be. When I look at the map of my walk or run, it looks like the GPS is turning on and off almost rhythmically. Anyone have this issue?
I have a V7 watch and a V14 phone. When outdoor cycling I would get the dreaded "dashed grey line" where the GPS was not recording and then magically reappeared in a solid colored line. I ran a test where I cycled the same course over four months with three different scenarios - one with just my watch, one with my phone powered down and the third with my phone powered up. When I just wore my watch or carried my powered off phone (a total of about eighty times) I ever got a dashed grey line AND the distance recorded was the same (within .05 of a mile). For the thirty something days that I had my watch powered on, 85% of the time I had dashed grey lines and the distance recorded varied by about .7 of a mile. I know Apple says carry your phone for better accuracy but it is just not true.
If you want more accurate recording power your phone off before you start you exercise.

GPS turning on and off?
