Inaccurate sleep tracking watch 8

SuperPicard — Sat, 14 Mar 2026 11:35:57 GMT

Hi,

For a long time my watch 8 does not track sleep accurately. REM and Deep sleep are low and also many nights if I wake up in the middle of night or go to the bathroom it stops tracking.

The latest February 2026 uodate has not fixed the issue.

Thus is really poor customer experience and I would have expected more attention to something like this. I mean if doesn't do proper sleep tracking what the hell do I want the watch for?

COME ON SAMSUNG!!!!

I think you may have an issue with the expectations on the watch. Sleep tracking is not accurate in any smartwatch or fitness band. They are just some approximations, based on a set of algorithms whose main input is the reflected colour of the blood.

Additionally, there is no scientific evidence related to sleep cycles and what constitutes a good balance. Measuring the with the imperfect instruments we have in the form of smartwatches does not achieve anything meaningful and may only contribute to increase ansiety.

I am sorry if the only use you find for your watch is sleep tracking. You have the wrong toolbfor that.

I have a similar issue with a sudden drop in Deep sleep detection on my Galaxy Watch5 Pro. Ever since the OneUI8.0 upgrade at end of last December, deep sleep detection has been poor - a step change from before the upgrade

Here to say that my watch just doesn't track my sleep at all now. It worked fine when I got it, I always make sure its up to date but it refuses to work at all. Of course its out of warranty now so theres nothing I can do.
Really disappointed.

"Nothing" is too strong a word. Depending on the model you got, it is possible that you are suffering from a bug in the latest version of the software, if I recall correctly. If this is te case, you may need to wait for an update (expected one update every quarter).

You can create a backup (the watch usually nags you if you don't set it up) and reset it to factory settings. And if the software gods allow it, your watch may start recording some data from your sleep. Since this process is a lot faster than resetting a phone, it is something that you could easily try.

Thank you so much, I'm going to do that now. I gave up before but I don't think I've actually done a full factory reset. Fingers crossed that sorts it out. 😊
