Sleep

[wmujcc]

My Charge 2 stopped showing sleep stages a week ago and now only gives me sleep patterns.  Why did it stop and when will we get a software update to fix the problem.

Fitbit suggests that there are a number of possible reasons for not showing sleep stages. They say:

"There are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of 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?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

For more information about why you see your sleep pattern, tap or click the sleep record that shows your sleep pattern."
