Accurate calorie tracking - use of heart rate?

[jamesharvey94]

Hi all 

I have recently purchased a Galaxy Watch and was disappointed to see that Samsung Health only utilises Heart Rate for calculations of Calories burnt whilst either running or walking. For all other exercises, as I understand it, a fixed factor determined by perceived intensity is used. This means for a person of set BMR, calories burnt in a fixed time will not change regardless of actual effort expended. This is not only completely bonkers, but sheer laziness and actually just not really acceptable for a device which markets itself as a fitness wearable and actively measures heart rate.

The formula used to calculate calories burnt which factors in heart rate is well documented. Why is this not implemented in all exercises so that it gives an accurate reading, like in Garmin devices and my Wahoo chest strap? 

I realise this is not all the watch is about, but it pretty much renders the device pointless for any exercise tracking as long as my 40 minute HIIT workouts where I spike 180bpm have me burning just over 300 calories...

Please can this be sorted?!

Same problem here it seems like such an easy fix that it's disturbing that they didn't try it between that and my deep sleep being recorded improperly I think I'm going to return this watch.

Yeah, I bought the Watch5, am seeing all those exercises, around a 100 of them, but when I saw that when you turn them on, they just burn calories by elapsed time (like for example when I forget to pause the exercise, or the watch is under 3 sleeves when I'm snowboarding and resting), I was surprized. Not only the intensity option which was added to Active2 for some activities is gone, but the exercise now is just a stopwatch which shows you your heartrate (and doesn't show pause time).. What's the point then? I can just google the calorie/minute ratio and just use a stopwatch..
