sleep tracking

[hyeonwoo]

Is the sleep tracking function activated on fitbit charge 6 without a Bluetooth connection? If I measure sleep for about 3 days without Bluetooth and then connect Bluetooth 3 days later, can I get the data?

Hi, @hyeonwoo your Fitbit should store detailed data, including sleep, for about 5 days, so you should be fine, as long as the Fitbit actually was tracking your sleep.  I would not leave it longer then about 3 days, however, as you may start to lose some data.

I hope this helps.  Welcome to the forums.
