I've noticed the sleep tracking is quite bugged out on my Galaxy Watch 3 (compared with my 2018 Galaxy Watch). It's been giving me extremely low sleep scores (~45-52) and saying my deep sleep is lower than 30 minutes or sometimes 45 minutes. Sometimes, it gives me two sleep records (a long-going bug that's been a thing since the Gear S2--if you wake up to pee, it counts as awake, still not fixed). I've had to delete the records in the Health app and manually correct them, as it constantly pings me saying I'm not sleeping enough when in reality I am.
I have tried setting the heart rate to continuous, but it just made the problem worse. So I went out and bought an Amazfit GTS as a 'second opinion' to see if the records would be any different, and in fact, they were! In fact, I'm getting 74 sleep scores, and it showed my deep sleep as 1 hour 45 minutes and REM as 2 hours, light sleep as 7 hours (total sleep time 10 hours). While the Galaxy Watch 3 showed 45 minutes deep sleep, 30 minutes REM, and light sleep of 1 hour 25 minutes, 2 hours plus awake, and pinged me 'Your deep sleep is low!'.
Obviously there's something wrong with the Galaxy Watch 3 since I feel great, I don't feel tired, and sometimes if I do sleep horribly (like 3 hours!) it gives me an 'excellent' score in the 80s! I can't find any way to recalibrate the sleep tracking, and I've updated Health to no avail, and there's no updates to any watch app. I love the Watch 3 as it's faster than the first Watch but sleep tracking is dead. I don't think it's ever registered more than 45 minutes of deep sleep--that's the highest it's given me. It usually shows either a zero or 30 minutes. Sometimes, it matches or goes above and beyond the 'benchmarks' (hash marks where I should be in any stage) but scores me low for no real reason. The inaccurate 'awake' time often is when I remember dreaming or if I wake up to go to work, where it isn't coming out of sleep tracking mode, thus throwing off the total number.
I can't think of anything to explain the vast discrepency of the two records from the two watches. The Amazfit seems to do far better than the Watch 3.
