I haven't tried this yet but a friend of mine who has a Mavic with Goggles said that if he does not hook his iPhone to the RC that his distance, when using Goggles, is limited to 150 meters (I think that was the number he said) whereas when he is using the RC with his iPhone and NO goggles he can go miles. Human error or have others had this happen? I just got my Goggles and we are having high winds so I can't test yet to see what happens with mine.
