I usually use a strap and don’t rely on the wrist hr when running
few months ago I ran without the strap just to see how good the wrist hr was in the 955 and it felt accurate enough
today I warmed up for 5 minutes on a rowing machine without starting an activity on the watch. At the end of my 5 minutes the watch face kept saying 75bpm. It was snug in the wrist and when I stopped I kept watching it while counting my heart beats.
I was at about 150 and the watch kept showing 75
has anybody experienced this? Again, I had not started an activity
For the rest of the time in the gym I kept an eye on it and it would show maybe 92. Counting I was at 135 or 140 usually. As a test I started an indoor activity and quickly the hr rose to 140. The sensor clearly works
now, I don’t expect (and don’t want) the sensor to monitor my hr super frequently when not in an activity, because it obviously drains the battery faster. But how often does it sample?
Isn’t 5 minutes on a rowing machine enough to get another sample and notice that I am not at 75bpm anymore? And I am ignoring the fact that I kept lifting weights for well longer than that and it barely changed
Was it always like this? Or are these changes to extend the battery life? (And in that case, the hr out of an activity is good only to monitor sleep, because it won’t pick up the changes if I go on a walk for example)
I am on 14.20
