New Charge 4 won't track my sleep stages

[bwlstamps1]

I recently bought a new charge 4 because my old one had stopped showing sleep stages and health metrics. Unfortunately the new one hasn’t improved matters. Still no sleep stages or health metrics. I’ve followed all the advice to no avail. What has gone wrong. BW.

Hi there, @bwlstamps1. Thanks for stopping by in the Community Forums and trying to troubleshoot the issue with your Charge 4 before posting here. 

As a first approach, I suggest resetting your heart rate to make sure your Charge 4 can measure it accurately in order for your sleep data to also be accurately:

• Switch the Heart Rate settings from On to Off and manually sync your watch. To switch the heart rate settings on your watch, from the main screen of your watch, swipe left until you see "Settings", next swipe up until you see "Heart Rate" and switch it to Off.
• Once it's done, manually sync your Fitbit device. To do so, open the Fitbit app, tap on the Account icon, tap on your Fitbit device's image and tap on "Sync Now" 
• Next, switch it from Off to On and manually sync your watch once again. 
• Once it's done, restart your Fitbit device. 
• Next, confirm that your tracker is snug on your wrist (the lights shouldn't be visible) We also recommend when you're not exercising, wear the tracker just above the wrist bone.

Additionally, I recommend considering the following in order to get 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 with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.
