Sleep Monitoring

Hi All,

I have a Fenix 5s and would like to track my sleep patterns, but there appears to be major issues with this in Garmin Connect.

1. I have to wait at least 30 minutes after waking before it will give me any info at all.

2. As the day proceeds, the sleep info changes. For example, when it first sinks it might say I got 48 minutes deep sleep and then if I open the app in another hour it will say I got 20 minutes deep sleep, but later in the day it might say 30 minutes. Light sleep, REM sleep and awake periods are also affected. It appears that it is taking into account my non-sleep activity when doing it's calculations. It can also say I was awake when I wasn't and maybe in deep sleep when I was awake, etc.

Garmin's sleep analysis algorithms are severely flawed!

If I remember correctly, Fenix 5 has Garmin's older sleep analysis, which happens on the server side after syncing with the watch. That's why it takes some time to appear, and what appears first is a "quick" analysis, which is then a while later replaced by a somehow "better" analysis.

And yes (having had Fenix 5+), the older sleep analysis is definitely not as good as the new in-watch one. Which is not that surprising, because it's based on the normal 24/7 data recorded by the watch during the night, not dedicated sleep analysis done during the sleep.

Thanks for that. Apart from the sleep analysis, the watch works great and it would be a shame to replace it. One thing to note is that the sleep analysis doesn't just change the once, it changes almost every time I open the app on the phone. Although calories burned seems a little off as well. I did over 12,000 steps yesterday and an exercise routine before dinner and hadn't burned as many calories as I had the previous day with a third of the steps and no exercise. Then once I sat down to eat and relaxed for the rest of the evening I burned another 400 calories - go figure!
