Why did my vivosmart 5 record stress levels and even heart rate for 4 hours yesterday when I wasn't even wearing it?
I went to the beach yesterday and left my watch in my bag the whole time. During the 4 hours thaf it recorded "data", we would walk a little while, stop and swim awhile, walk some more, swim some more, walk, sit down and eat etc. But the whole time I wasn't wearing the watch...so I'm really confused on how it "measured" my stress level or heart rate!. Admittedly, it didn't record data for the rest of the day when it was sitting in the boot of the car. But it can't have even been estimating my levels based on movement, because a lot of the time it was just sitting still un the bag while we swam etc! Now I'm wondering if I've been duped and this watch was a waste of money. I've had it just under 18 months and the software is up to date.
