In my gym session, my Charge 5 (in Workout mode) has consistently given readings of 120 to150 bpm at times. I've also had similar readings for 5 to 10 min after the session, when cooling down.
Checking this with other devices (eg pulse oximeter, Polar HR strap) has shown a much lower HR, typically 100 to 110.
I also had incorrect readings on a walk using the Workout mode. My typical walks are 10 to 20 mins and reasonably brisk, but the HR is always under 110. Using Workout mode it showed HR again in the 120 to 140 range. It felt no different from a normal walk.
From this it seems obvious that the measurement of HR is different in the two modes, and probably incorrect in Workout mode.
Anyone got any idea what's going on?
