Hi, I did own a series 1 Apple Watch after last Christmas - for two days, then I returned it. There were some annoyances and I couldn't justify the 350€ that time. The last weeks I am contemplating with the watch AGAIN. I don't really know what to do with this urge since I decided against the watch half a year ago. One annoyance was when I was working out and afterwards my 5S was nearly dead. I figured it must have used the gps for the "other" workout I started. Does it always use gps? I remember choosing it to be the only way to track strength training (renaming it afterwards). How do you do it in your case? Thanks!
