I use my Apple Watch SE2 and Sleep Cycle app on my iPhone to track my sleep since they do different things. Sometimes the discrepancy between the two in recording how much I slept is crazy - last night Sleep Cycle says I slept 6h23 and my Apple Watch says I got 8h10. Which is actually more accurate as far as sleep duration goes?
Ever since all those changes last year it’s honestly not reliable or accurate anymore. I’ve logged 3014 nights and it no longer detects when I’m awake and using my phone, doesn’t detect when I fall asleep after the wake period or will say I’m awake when I’m asleep. So annoyed.
The only difference between Sunday and Monday was I had the fan closer to the bed on Monday so it didnt pick up my movements nearly as well, as can be seen by the graph. My question though, is shouldnt Monday nights quality rating be considerably lower than Sundays, rather than better, even if just by 1%
I've since found the microphone to be very unreliable, using the accelerometer and putting the phone right next to the pillow seems to work much better.
