Sleep data is off by hours

[Sunsetdollars]

Last year I noticed that the sleep data that my fitbit was recording started to decrease. At first it was only by a few hours but now it's only showing I'm sleeping an hour or less per night. I was using a charge 2 and thought the device was defective so I tried a charge 3 which was getting the same results. I am now trying a versa lite and again its only showing an hour or less per night. I know I'm sleeping more than it's recording but I'm getting really frustrated with the poor tracking of my sleep.

I have followed all the advice and suggestions you supplied with no change.
I actually had a 72 hour at home eeg study and to compare the sleep data
with their readings and the fitbit was night and day. The fitbit devices
only showed me sleeping 46 minutes the first night, 23 minutes the second
and again 23 minutes the third night where they got between 6 and 7.5 hours
each night.

Are you telling the app to "Begin Sleep Now" or are you just falling asleep normally with the watch on? Normally if you sleep for less than 60 minutes without telling the app, nothing at all gets logged. I would also be curious as to how much time awake was logged by fitbit during that sleep study. If you toss and turn a lot naturally it could potentially be confusing the watch.

I've never tried the sleep now function but I will tonight.. Up until Oct
last year the fitbit was recording fine and i was consistently showing 7-9
hours of sleep every night but then one day when I synced it in the morning
it went from
8 hours and gradually over time has gone down to as little as 18 minutes in
one night.

I've been trying the "Sleep now" function and I'm still getting the same result. Last night it said I only slept about an hour and a half which I know is incorrect.
