Hi, thank you for sharing your inquiry about tracking sleep with your Charge 5, @swabjockey.  

When your body is completely at rest and you haven’t moved for about an hour, your device should record that you’re asleep and after you sync your device, you should be able to see your sleep information on the Fitbit app. 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.
