The heart rate my Charge 5 is measuring is way way way lower than what my charge 3 was measuring.

 

I would routinely get Fat Burn Zone minutes in the range of two to three hours a day.  Now I am getting 2 to 3 MINUTES.

I think I figured it out.  The calculations for the zones is entirely different.

 

where my fat burn zone used to start at 84 ( 50% of my max heart rate), the new calculation has it starting at 104!

Why the enormous change Fit Bit?  It makes the years of data on my Charge 3 USELESS
