No deep sleep?

My Epix Gen 2 is not recording any deep sleep. For example, last night I recorded over 8hrs of sleep, 4hr REM, 0 Deep. Since receiving the watch weeks ago, it initially recorded a couple nights of minimal (20-30 min) deep sleep, but now its mostly "0". It is recording accurate sleep/awake times. The watch has no issue recording other metrics, including Pulse Ox, HRV, etc. There are no gaps in HR recording.

I have worn Oura ring for years. The Oura is recording deep sleep every night, including 1hr 55min last night! My previous Fenix 5 watch would typically record over an hour of deep sleep.

Is this a sensor issue? Pretty disappointing to see such poor tracking considering all the sensors on board.

    I always have deep sleep and REM sleep in my sleep results on the Epix.  I had 1 hour 11 minutes of deep sleep and 41 min of REM recorded last night and I have full results like that every night.  My fenix 6S was the same.  And my hours of sleep are always exact.  I've always been happy with the sleep feature.

    It is very likely that your actual deep sleep is much more than 1 hour and 11 minutes. But it's at least good enough to not trigger any strange flags/calculations for the body battery etc. so that's great.

    Well, I'm not delusional, I do understand that it is only a sport watch doing its best and that if I had my head connected to electrodes for a sleep study I'd get more accurate results.  But for what it is it seems to do a good job for me. :)

    There is nothing delusional about expecting a $1000 watch to somewhat accurately track your sleep cycles in 2022. Most cheap fitbits and even Garmin's own 180 USD watch, the vivomove sport, is accurately tracking sleep cycles (scientifically tested: www.youtube.com/watch). That it shows more than an hour deep sleep for you is great, but that doesn't take away the fact that for most it doesn't track it accurately. You probably have above average deep sleep and in reality have 2+ hours. For you that doesn't mean any issues. But if you have average deep sleep, you will see most of the the time that you had "light sleep" or "not enough deep sleep". Sleep stats are also used in the body battery. So it is important that Garmin steps up their game and improves this. This has nothing to do with hardware, the answer lies somewhere in their software. I don't think that the 180 USD Garmin vivomove sport has better hardware than the fenix/epix. They can fix this. It is scientifically proven that the epix/fenix 7 are underperforming in sleep tracking: https://www.youtube.com/watch?v=Ka9LXKQy-fQ while the 180 dollar Garmin vivomove sport is doing it almost as great as fitbits: www.youtube.com/watch

    I have been suffering from poor sleep for a while now, for no apparent reason, and have been trying to identify why and what I can do to improve it. I have just got the Epix-2 and for the first week it didn't show any deep sleep at all. This week it has shown some most nights ranging from ~5mins up to about 1.5hrs.

    It would be great if I could get a consistent baseline, even if it's not super accurate. At least I could work with that.

    I guess it's a good thing that I didn't buy it primarily for sleep tracking then.  As I said, for me, it seems to be doing a good job and my body battery seems to be mostly accurate to how well I think I slept and how I feel when I wake up.

    Epix 2 has been tested now by the same guy that scientifically tested the Fenix 7 - It scores even worse in terms of sleep tracking:



    In the same video you'll also see that the Garmin Vivomove sport (180 USD) scores as one of the best in terms of sleep tracking. So this is not a hardware thing. Garmin really needs to improve the algorithm on Fenix/Epix devices.

    I don't know why garmin won't gives an answer.

    Maybe because for a lot of us the sleep tracking is working very well:

    I want the same algorithm as the vivoactive sport, according to a review the epic and the fenix is inferior to the vivoactive.
