Inspire HR calories burned are wrong

[New40]

So I've  literally  woken up and my Fitbit is telling me I've burned 700 calories which is impossible  while sleeping!. I've so many issues with this it's a week old should I just return it? Has anyone had better luck with the verso.

The calories may not be wrong.

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 and it's quite normal to have several hundred by the morning.

Ok thank you. Just trying to get used to this.

No problem. There's a lot to get used to when you start with Fitbit and BMR calories trip a lot of people up.
