Charge 3 not tracking sleep accurately

[Rawrgirls]

The last few nights my sleep tracker randomly stops at 3 something in the morning even though I actually wake up at 6:15. The first night I assumed maybe I was sleeping on my arm funny- that wouldn’t happen over and over! After reading a lot of these posts I’m starting to wonder if the charge 3 isn’t nearly as quality as my old charge 2 that I had for 3-4 years?!?

Hi there @Rawrgirls, welcome to the Community Forums. Thanks for the details provided, I'll be glad to help you. 

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?
