Sleep data not working well

Hi,

I have had the 955 for about 10 days.

On two mornings sleep continued to be recorded after I had looked at the morning report and synced to Connect. The result was that the sleep score was hugely reduced and this affected the training readiness for the next couple of days. I tried correcting the data on Connect, but the sleep score does not change on the device.

This afternoon was even worse as the device decided I was asleep at 12.40 and I did not notice until 5.30. My sleep score is now 0 on the device, a drop of 84 points since this morning. Connect still has my results from last night but syncing does not correct the data on the 955.

Any ideas?

I have the same issues unfortunately and have asked a similar question. Have you resolved your problem?

No. It did the same today.

I returned my 955 today for a refund. Its either a hardware or software problem. Not acceptable accuracy! Shame!

Garmin definitely have a problem with the 955 tracking sleep properly! I returned a 955 solar with this problem and the replacement 955 non solar has the same issue - recording rest outside of the sleep window as sleep. This error then affects the physio metrics!

I have the same issue for 955. My sleep score has been always below 50 since I got the watch in mid July. It detected and recorded my afternoon nap once. Most of time it showed I had more than 2 hour wake time during night sleep. I think there is something wrong with move detection threshold. It won't bother me if the sleep score is not part of training readiness calculation.
