Charge 2 shows simplified sleep data

[NickiSenior]

For the last 4 weeks I have got simplified sleep data from my charge 2. I have followed all the instructions in the forums for wrist placement strap tightness etc. I’ve reset the watch and I’ve unpaired it/repaired it with no solution. Anyone anymore ideas? Seriously close to calling it a day with Fitbit as this is my second (first the screen split just out of warranty). Also out of warranty now.

@NickiSenior A warm welcome to our Community!

Let me help you with your simplified sleep data and thank you for troubleshooting this issue. You may not get sleep data for the following reasons:

• 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.

I suggest you clean the back of your device with cotton and rubbing alcohol and restart it. Turn the heart rate off, save and sync then turn it on save and sync again. Also check these tips to improve the heart rate reading on your device.  

Let me know how it goes.
