Charge 5 didn't record my sleep

[AmandaThiel]

I bought the charge 5 to track sleep. I even acquiesced and paid for premium.  So far it stinks.  I changed the sensitivity to sensitive for sleep and the stupid thing didn't record my sleep,  said it couldn't find heartbeat?? It's in the same place as always,  on my arm!!

Welcome to the Fitbit Community forums, @AmandaThiel. 

Thank you for sharing all of your feedback and for this information about the inconvenience you've been experiencing with the new Charge 5.  

Keep in mind that when your body is completely at rest and you haven’t moved for about an hour, your device should record that you’re asleep. Before considering other options, please keep in mind that there are some factors that may prevent your tracker from recording your sleep. Please make sure of 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 as described in this help article.
• If you slept for less than 1 hour for sleep patterns or less than 3 hours for sleep stages.
• If your device’s battery is critically low.

If you haven't done so already, please follow the steps listed here below: 

1. Complete a three pulse restart procedure using the charging cable. 
1. Try adjusting the sleep sensitivity on the Fitbit app and check if you continue to have the same problem.

In addition, please wear your device on your non-dominant hand and monitor it for the next few days. In the meantime, for the nights that don't have sleep data, you can manually log your sleep by going to the Fitbit app, tapping on the "+" icon next to the sleep tile > Add Sleep Log and entering your details.
