Charge 4 stopped tracking my sleep stages

[Aido90]

Charge 4 isn’t giving sleep stages or sleep score. I’ve tried deleting and reinstalling app, resetting the charge 4 while plugged in charging but still the same

Hi there, @Aido90. Welcome to the Community Forums. Thanks for trying to troubleshoot the issue with your Charge 4 before reaching out.

Please note that in order for you to receive a sleep score, your Charge 4 should also track sleep stages. While there are some factors that could prevent the sleep stages to be tracked, I recommend taking into consideration the following: 

1. 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.
2. 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?
3. If you slept for less than 3 hours.
4. If your device’s battery is critically low.

For more information, you can see: What should I know about Fitbit sleep stages?

Hope this helps.

Bonjour,

My Charge3 had exactly the same problem, not tracking my sleep. It end up that the hearth beat sensor was defective... exactly 2y and 3 days after i set it...One i realized that, i went to see my hearth beat log and could find exactly the day and hour when it stop working !

We had 3x Charge 3 and 2 of them became defective (display, hearth beat sensor) within 2y and 2m... which mage me reflect of the quality of these products especially after i red on this forum that many many people ha the same problems.

Well the same thing has happened with my charge for and I know how to push the sleep now button and if it messed up before I've even went back two or three months erased it and then when you put it in it computes it into the stages and gives you a score so I have scores all the way to the beginning few weeks that'll have been six or seven months ago now and now all of a sudden four days ago you can see the basic bar of sleep and it's colored and it's got lines through it but it's not the analysis of sleep stages or my heart beats or my skin temperature or how many milliseconds between each heart rate which is messing up all of my stuff for me running and everything it's making my heart rate look higher than it actually is so all that advice you gave isn't going to help anything especially he wrote his thing around the same time mine started doing the same thing all of a sudden it just stopped and that was and I haven't been able to get it fixed or fix it ever since and I haven't had mine that long
