Mine was absolute crap at sleep detection. Typically it would report that I fell asleep before I went to bed, or I was asleep longer than I was in bed. Heart rate detection and so on was generally fine through the night, as was Hrv. I sort of wonder if the actual sleep detection is done on the phone, and if the phone is not nearby, it just fails. (My phone doesn’t go to the bedroom. Makes it far easier to actually sleep) (Also, Watch is dead now, and didn’t replace it, so I might be misremembering the exact bits, but the results were generally paradoxical)
