Charge 3 wont show sleep stages

[Charli2207]

Hi all. Got a charge 3 recently and for 2 nights it just showed awake restless ot asleep no sleep stage information.  The next night it showed rem light and deep as well as the normal sleep awake etc. Now its gone back and showed the basic asleep awak restless. Is there anything i may have done by accidentally changing setting etc? Or is it just pick of the luck whether it actually detects them? Ive got it set to sensitive as it was just set to normal as per advice from fitbit but it hasnt changed anything. Many thanks

@Charli2207 I hope you're doing well!

Let me help you with this and thank you for troubleshooting this issue. Sleep stages may not show for the following reasons:

• 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.

Hope this helps.

Are you suggesting then that i dont choose the sleep now i just literally fall asleep without setting anything? Because my husband set his sleep now and it gave the readings? So dont see how thats different but ill give your way a go tonight and see.
