CAUTION. Incident detection and assistance are supplemental features and should not be relied on as a primary method to obtain emergency assistance. The Garmin Connect™ app does not contact emergency services on your behalf. The fēnix® 5/5S/5X Plus device has safety and tracking features that must be set up with the Garmin Connect app. I remember having 15% left after a 8 hours long race, with some data screens. Same for swimming sessions (in swimming pool, not open water): the fenix 5s seems to loose 10% every hour where the VAHR battery loss is at around 6-7% if not less. That's quite disappointing, there's no way it'll last 11 hours, I'm not even sure about 5 hours. Moving on to the 6S Pro, dropping 31 grams from the 5 Plus with a 42 mm diameter it is a much more appropriate watch for me. I may have chosen this size watch sooner, though battery life for the 5S and 5S Plus was limited. With the jump to ~22 hours in the 6S Pro, this was the game changer I was looking for.
