Calories count does not make sense when swimming

When I walk, my Fitbit 6 estimates my calories count around 400/hour, with heart rate being around 105 in average.

when I swim, I get only 150 calories/hour with an average heart rate of 140.

That does not make any sense to me. It seems like the swimming activity has the calories count totally wrong.

Does anyone experience the same issue ?

Hi @GerLech and welcome back to the forums. 

I appreciate your message, and I'm sorry to hear about this issue regarding the accuracy of your Charge 6. 

Could you please verify if the pool length is updated in your Fitbit app? How do I set the pool length for my Fitbit device?

Here is some data that shows how unreliable the count can be:

day1, distance 1500m, heart beat 152, calories’ count 115

day2, distance 1700m, heart beat 149, calories’ count 404
