Sleep not fully tracked - Watch Pro 3

Ozzy

I’ve had the watch pro 3 for about 4 days and sleep has been logged ok, but this morning I checked and it hasn’t fully logged, stopped around 01:47.

Ozzy I’m experiencing something similar on my CMF Watch Pro 2. Sleep tracking sometimes stops midway.
Hopefully Nothing is still paying close attention to their smartwatch lineup.

Ozzy

Dimas oh really that’s a shame, I don’t expect accuracy like other brands but at least record a full night’s sleep.

How do we escalate this in case they don’t realise?

Dimas

Ozzy Yeah, I’ve sent feedback and improvement suggestions multiple times via the Nothing X app, and they were always acknowledged by the Nothing support team.

That said, it does feel like the CMF Watch Pro 2 hasn’t been a top priority for updates lately, at least based on my experience.

You should definitely still try submitting feedback though, especially since you’re using the newer CMF Watch Pro 3. Hopefully that helps bring more attention to it.

Ozzy

Dimas I’ve sent them feedback just now with watch logs etc, hopefully they’ll pick this up, I also mentioned posting on the forum and watch pro 2 having ongoing issues as well.

Thanks 👍

Dimas

Ozzy sounds great and good luck ! Hopefully we will get more firmware updates for our watch.

Dimas so support came back to me with a list of things to try, see below.

The only thing I could think of is that I have sleep standby optimisation turned on in my battery settings, so I’ve turned that off for now and see how we get on.

To help resolve this issue, I’d like to suggest some troubleshooting steps:

Check App Connection: Ensure your watch maintains a stable connection with your phone throughout the night

Update Firmware: Verify both your watch and companion app have the latest updates installed

Restart Your Watch: Power off your watch completely, then turn it back on

Battery Optimization: Make sure battery optimization settings aren’t interfering with sleep tracking

Wear Position: Confirm the watch is worn snugly but comfortably on your wrist

Clear Cache: Try clearing the cache in the companion app

Ozzy That makes sense. CMF Watch Pro 2 doesn’t have battery optimisation on the watch itself, so it’s likely related to Android battery optimisation for the Nothing X app. Those settings can definitely affect background sync, including sleep data.

Hopefully disabling battery optimisation helps deliver more consistent and complete sleep tracking results over the next few nights.
