Charge 3 not tracking sleep stages

[Londonlucy7]

Hello 

I got a charge 3 for Christmas. 
the sleep stages are showing ad hocly. 

I have tracked my sleeps most night but sleep stages have only come up twice. Otherwise it’s showing me basic data. 
I was enjoying the sleep stages data. 

please help.

Hi @Londonlucy7, welcome to the Community Forums. Thanks for the details provided about how your Charge 3 is tracking your sleep. 

If you are not receiving sleep stages, I recommend considering the following:

• 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?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

Keep in mind that you must see sleep stages in order to see your sleep score information. Please swipe left on the Sleep Score graph, here you can see information about your weekly sleep average and sleep duration. To get more detailed information, see: What's sleep score in the Fitbit app?

I hope this helps, give this a go and let me know if next time your Charge 3 provides you with your sleep data.
