No more deep sleep on fenix 6 pro

Since i moved from fenix 5 to fenix 6 pro i don’t see deep sleep anymore...

also a bug?

  • I get about the same amount of deep sleep as I did at my Fenix 5X. If any, usually is at the first hours of my sleep time.

  • 6x sapphire. After the last update, i cant see deep sleep

    Same problem here. I switched from 735xt. Before the switch I saw couple of phases of REM/NREM each night. First measurement on fenix 6 had no deep sleep at all. Then I’ve upgraded firmware to 4.20 and now it detects 15-20 min of nrem at the begging of the sleep. Every single night same way. I’ve chcecked number of data packets synced with my iPhone. On 735xt it was 5-15, on fenix it’s like 2-4. I’m pretty disappointed with this. 

  • I can confirm that it is still happening. Only a tiny bit of deep sleep at beginning of night. Other trackers I had before (and were just 1/6th of the cost) tracked sleep properly. How is it possible that Garmin hasn't fixed it yet after all this time? A watch at this pricetag should track sleep correctly. Highly dissapointed because I like the watch and other metrics it tracks, but sleep is very important for me. Wearing the watch tightly around the wrist, not loose. I have light skin, I have no tattoos. So the sensors can do there work properly. What's up Garmin?

  • Same here. Fenix 6s pro, software ver 19.20.

    There are 3 patterns for me:

    1. Many nights have no deep sleep at all, despite 8 to 10 hours of sleep.

    2. Many nights have a few minutes of deep sleep only at the beginning.

    3. A few nights have normal deep sleep tracking; up to 1 hour of accumuliated of scattered deep sleeps.

    * these patterns are not in order (not fixed by software), they still happen.
