Charge 2 not showing sleep stages

[noodlebugs]

Unable to get sleep cycles.  I have switched wrist,  moved up 3 inches on wrist, reset app, charge battery to full,  sleep with arm on pillow not to be moving during night, let Charge 2 track automatically,  placed heartbeats to on, put heartbeats to automatic, put glove on so Charge 2 doesn't move and still only gives me time.  Last sleep cycle was registered in August 2018.  No sleep cycles since August and have no solutions.

@noodlebugs Welcome! Thanks for being part of our Community! Sorry to hear that your Charge 2 isn't getting sleep stages and thank you for troubleshooting this issue. You may not get sleep stages 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.

You can also clean the back of the tracker with cotton and rubbing alcohol and then restart it to see if this helps.

Let me know how it goes!

I tried these solution numerous times and still only get time.  I have tried different sleep positions.  I usually sleep 8 to 9 hours.

That is just the stock answer, I have had the same problem in the past & was just told the same thing!

I have recently received a replacement Charge 2 due to screen cracking problems. I wear it exactly the same as I have worn it previously and out of the past 3 weeks I have only had Stages twice I think. Where as I have had almost no problems with Sleep Stages on my old device for months, I have Sleep Apnoea & rely on the app for info. I am going to look at other companies alternatives as this Charge 2 is not fulfilling my needs, too many problems & too much frustration.

Your suggestions did not work out.

I have exactly the same experience.

After some research,  I believe it is my AF  (atrial fibrilattion ie. irregular heartbeat).  I understand that the iWatch 4 now has an algorithm to handle this,  bought one then returned when I found out the battery only goes 18 hrs. max, with no other background apps going.  Not exactly functional if you put it on in the morn @6:00 am,  it poops out somethime in the night ie. incomplete heart and sleep data.

Sorry,  don't know of any fix.
