Fitbit versa registering calories I haven’t burned

[Sophiemullarkey]

I put my Fitbit on charge last night and took it off this morning. 
when I put it on step count was 0 but calories were already 600? 
it was on charge before 12 am, at which time it automatically resets so it can’t be from before putting it on charge.

Any ideas/anyone else had the same problem?

This is quite normal.

As well as tracking calories burned through activity your fitbit also tracks your BMR calories. These are the calories you burn just keeping your body alive (even when asleep). They are calculated from your profile settings for age, height, weight etc so you needn't be wearing your fitbit to get them. What you are seeing includes the total BMR calories burned since midnight
