Inspire 2 is not tracking my sleep data constantly

[Deborah120]

My Fitbit is tracking my sleep every other night. But it’s tracking my steps every day as usual. Anybody have any ideas about why it would track sleep every other day? Thanks very much for any help. Using iPhone 13.

Hi there, @Deborah120. Thanks for stopping by in the Community Forums and sharing the details about the issue with your Inspire 2. 

There are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.
