TLDR: The S3 LTE and AirPods make an awesome workout combination that work as advertised. Still, a few minor questions remain. Took the watch (SS S3 LTE) on a run with AirPods... Here are some thoughts: To transition from my house wifi and iPhone took about 30 or seconds. Nothing major but noticeable. During my warmup I tested out the text function through Siri... worked quickly and accurately. Siri in general seems to be working better lately. I am not sure if this due to improvements made by apple or the fact that Siri has forced me to work on my own pronunciation. I ddi received an unsolicited work text during my run that I was able to respond to quickly and (again) accurately. The is exactly the reason I wanted LTE. All aspects of playing music worked well, as it should. This will become more interesting when music streaming arrives. Battery started at 75% (wore it over night, charged for a few minutes prior to run to update music) and ended at 57% in approximately 45 minutes on LTE (18%). Heart rate... still had some moments where it had difficultly reading it but by and large it was noticeably improved from my S0. S0 usually spent half or more of a run trying to read my HR. With the S3 I only saw this occur once. VO2 max... a fun new feature although I have no real way to immediately verify the accuracy for this. In general the watch performed well and was noticeably smoother in all aspects from my series 0. I said it in a previous thread but this feels like the watch I wanted from the beginning. This run also raised some questions: 1. Recovery rate... where is it? I was unable to locate this on my watch or iPhone? Edited to add: I have now located this... It may just take it awhile to show up. It is under the workouts on the activity app (I did not initially look here) and on the watch it can be found on the heart rate app (first place I looked... but apparently it takes 5+ minutes to show up?). 2. My max HR hit 209 on a hill sprint. Still at 39 years of age this seems too high. My question is whether or not there have been accuracy issues for anyone else, especially in the upper HR range? I actually experienced (verified by a tickr X) inaccurate readings early on on my S0 but these went away after one of the early software updates. I set a reminder (through Siri and my AirPods) on my cool down walk to schedule an EKG on Monday morning but I lean more towards their is nothing wrong with my heart (even if the watch is completely accurate). I might ask for a stress test and VO2 max while I'm there (and any other testing they will give me haha).
