Ran the Boston Half today with my new AW3 LTE, leaving my phone in the hotel. Some impressions, both good and not so good... Let the hotel at around 6:45 with a full charge and returned at 11:45 with 33% still left. LTE was turned on throughout. My time running was 2 hours and 9 minutes. I was playing locally stored music during all that time to my Powerbeats earphones. I made a couple of calls during the course of the morning, sent and received a few texts, and tracked my daughter who was also running the race using Find My Friends. I’d say that is not bad battery-wise. The cellular functions worked great. No problems whatsoever. My main concern is that I’m not sure how accurately it captured the distance. I was using the built-in Workout app and it showed my distance as 13.52. I realize that one typically would expect something higher than 13.1, because of inefficiencies in running the course, weaving, and so forth. But I generally make a point of taking curves along the course in the most efficient way and 13.52 seems on the high side. I’ve run races before with the S2 and the built-in Workout app and generally found it to appear accurate. I wouldn’t have thought that the S3 would be less accurate. To the contrary, I thought the LTE would improve accuracy. But who knows? Oddly, the splits aren’t showing up in the Activity app on my phone, although all the other data — including the map — are there. Never had that happen before. So mixed views overall. However, I really liked being able to do something like this without my phone but while still being connected.
