Unreliable calories burned reading

[Nadavrot]

Just woke up an hour ago, the only thing I had done was to brush my teeth and make coffee though the info on the watch tells me I burnt 600 plus calories.

I hate that feeling that I can't trust the information..

Actually, that sounds like it's working fine.

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

Does this work even if you have not even worn it all night!? Surley not!

@FeeWonderWoman2 yes, your BMR calories are tracked even if your fitbit is sitting on the bedside table all night. It doesn't need to be worn as they are calculated just from your profile settings so it doesn't need the fitbit to track your activity.
