Fitbit Versa calories upon waking

[SnehaHouji]

I am a new Fitbit user, I bought Versa yesterday. I saw an issue where I removed my Fitbit at night and kept it on a table, when I woke up this morning, I saw that I had burned 400 calories throughout night, this showed up when I was not even using it & had 0 steps. I think its incorrect, What is the solution to this?

Fitbit calculates the amount of calories when you sleep. You are constantly burning calories even when you are sleeping so the Fitbit is correct. There is nothing wrong with it.

A warm welcome to the Community @SnehaHouji and @Jayelo thanks for stopping by.

Our friend here is right, the value that you see on your watch when you wake up in the morning is your estimated calorie burn for the day so far. You still burn calories even if you have been sedentary or were sleeping. We estimate your calorie burn based on your age, gender, height and weight.

For more information, you can check the help article How does Fitbit estimate how many calories I've burned?.
