New FR945: Horrible sleep tracking

After wearing a FR935 24x7 for two years other than showering and charging, I was always very impressed with the sleep tracking which I would examine every day.

Not so much with the new FR945, the sleep tracking is extremely inaccurate and disappointing. Only once or twice in the week of owning the new FR945 has the sleep tracking been accurate in my opinion. It thinks I fell asleep two-three hours after I actually was, says I was awake for 30 minutes in the middle of the night when I know I was not, etc etc.

Is anyone else experiencing the same with firmware 2.50?

Yes, same here. It is always much less than the actual sleep time. Sometimes it’s like your experience and sometimes it just drops out for a period of time during the night

Exactly! Anyone else? Please chime in so we can get attention on this if indeed it is a issue many are experiencing. Hoping it is not a hardware issue.

I looked at the last week of data and it seems to be fine. The wakeup time is always spot on. The only place it has problems is the fall asleep time. I think that is understandable since I usually read when I go to bed and I don't think that there is much difference between sleeping and laying there quietly reading.

Mine also seems to be working fine. It even shows the 10-15 mins or so where the puppy has been waking me up in the night to relieve herself. Falling asleep and wake up times are pretty spot on too.

My sleep tracking seems to be perfect.

My wake up times are good, the falling asleep times are WAY off. As stated before, the sleep tracking on my FR935 is very impressive. I wear the 945 the same as the 935 and my habits are the same. Hmmmm

I don't have problems with the sleep time and wake time, but I do have the drop outs and blacked out periods during sleep though. I wear the watch snug enough to leave imprints the next morning so quite certain it's not too lose.

Going to sleep times are a bit off (due to reading/watching in bed), wake up times are fine. Overall I'd say its ok.
