For last month I have had frequent no sleep data readings with my Charge 4. I have adjusted my watch position and tightness on my wrist and rebooted my watch several times with no change. What do you advise?

Hi there, @Moonshadow50. Thanks for stopping by in the Fitbit Community Forums and trying to troubleshoot the issue with your Charge 4 before reaching out. 

In addition to the steps you've done, I suggest resetting the HR on your Charge 4 by following the steps below:

  • 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 Charge 4. To do so, open the Fitbit app, tap on the Account icon, tap on your Charge 4'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 watch once again. 
  • 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.

I am having the same experience. I tried all the steps recommended to fix this but still not getting sleep data regularly. This began when I updated the app. I have never had a problem in the 2 years of owning this device. I believe the app is causing the issue. Would love a solution because this makes the user experience terrible.
