New Charge 5 won't track my sleep data

[Vu1pecula]

I have had a Fitbit 3 & 4 and now after the 4 body broke I have a 5 purchased directly from Fitbit.  Since wearing it from June 2 in various positions on my wrist, I have only had 2 full sleep readings.  Curiously both on a Monday.  The rest are just the simplified version.  Can anyone explain why?  The watch is worn 2 fingers width above my wrist bone.

Welcome back to the Fitbit community, @Vu1pecula!

Sad to hear that you're having issues with sleep tracking on your device. I'd suggest setting up a sleep schedule to improve sleep tracking accuracy. Please have a look at "How do I set a sleep schedule in the Fitbit app?" following the link below to see how to do that:

You might also try changing sleep sensitivity to get better results. See "What's the difference between the normal and sensitive sleep setting?" in the link I've provided above for more information on that.

Hi there, @Vu1pecula. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Charge 5.

In addition to the tips and recommendations provided by @Talahthas, I recommend considering the following in order to get 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.
