I think that's because the Fitbit records the calories you burn just by existing. It can estimate the calories you burn while you sleep even when you're not wearing it.

@Zainmaddi Welcome to the Fitbit Community! Yes, just as @DeanaDeana said, Fitbit will calculate your BMR (Basal Metabolic Rate) which are the calories you burn with vital body functions such as breathing, heartbeat, and brain activity.
Hope this helps. See you around!
