My cal burn and fat burn have dropped since wearing my Versa 2

[HeatherR96]

I recently upgraded from a charge 2, which worked perfectly for 3 years, to a versa 2 and since then my cal burn and fatburn has dropped dramatically before i was burning on average 2500 cals per day now it is around 500 cals, i am following a fitness plan so it should be higher. Previously, i'd go for a walk and my heart rate would be in fatburn zone the whole time now it is just under zones. This is extremely disappointing and demotivating after upgrading my device. I have found myself going back to the charge 2 to get a much more accurate reading. Just goes to show upgrading is often not worth the money!! very dissapointed
