So I learned yesterday that auto-pause feature for hiking is utter rubbish. The Fenix 7 seems incapable of detecting movement, or at least is extremely slow at responding to changes in movement, which is surprising given how good the GPS accuracy is with Multi-Band GNSS enabled. When I was stopped to take a photo on my walk the watch would eventually detect that I wasn't moving and turn the GPS would then turn off. Only for me to discover 100 or so metres along the trail that the activity was still paused, and Strava just puts straight lines between points where the GPS has been switched off. So I’ve gone back to having auto-pause switched off for walking/running and just manually stop/start and only use auto-pause for cycling now.
Maybe Garmin should consider another mode where the GPS remains on but the watch automatically deletes data points in the same location so that you don’t lose any distance.
