Charge 3 not tracking sleep stages

[Adinapool16]

For the past week or so... seems to be after the last apple update... my Charge 3 does not always track my sleep! It will track it here and there but not always! It is very important for me to have this feature being a new mother and needing to know how much sleep I’m actually able to get!

Hi here @Adinapool16, welcome to the Community Forums. Thanks for the details provided about your sleep data, I'll be glad to help you. 😉 Congrats on your baby! 

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.

For more detailed information, see: What should I know about sleep stages?

Give this a go and let me know if next time you receive your sleep data.
