New night 5-6 August is ‘No Data’

My SPO2 never showed in the app actually. 

[Blihpo]

Good news (for me that is). All the sleep data has come back. It recorded my sleep last night and cycling back through the days, it all shows up again.

Glitch fixed, well this one anyway...

I have attached screen shots showing how the SpO2 app has stopped since the sleep data has been recommenced

Welcome to Fitbit! Where they break the app with an update, fix it 3 months later then break it again.

I love my charge 6 but the app has been progressively getting worse over time.  Sorry you had to find out in person.

[Jligh]

It’s back now!

Looks like yesterday's problem with sleep tracking is fixed.  It's working again this morning.  Thanks to the support team for quick response.

Dear StefanieFitbit

Are you referring to the changes made around 23 June 2025 that's made sleep data more or less worthless on the charge 6 App...refer to the "Inaccurate sleep on Charge 6" postings, or has their been a fix to the app since then?

---

Can't say I have seen it myself, but according to StefanieFitbit post "Your sleep tracking just got more accurate". 

‎If you’ve noticed that your sleep stages, sleep time and awake time have changed recently, you’re seeing our latest improvement in action. This is the first step in a series of upcoming improvements to improving our sleep tracking — so stay tuned to hear about these changes as soon as they happen. 

We understand that changes in your data can be surprising and appreciate your feedback. 

What changed?

We've updated our tracking technology. This is to provide a more precise measurement of your sleep stages. Our goal is to always give you the clearest and most accurate view of your health.

For example, you may see your awake time increase slightly as we now capture brief awakenings the old system missed. This is a normal part of sleep.

No, only happened yesterday

So have ours!

[Sara_mac]

Seems to be working ok today.

[TiredV]

Has the fix been since 24 June? Same problems with Inspire.  All my records appear as normal (ie 7 hours or more sleep almost every night) for about 1-2 seconds then are automatically recalculated to much less or completely disappear. 

[Fizzyworm]

Yes eventually spoke with Support who had received other reports and they would follow up. Today all working . Much appreciation to the Support line

My sleep data came back just over 12 hrs ago

[whollis]

Is this only for Android?  Because since the silent release of new flawed algorithm my sleep results are absurd.  I also believe you've been misinformed since "restless" time was captured previously include in light sleep, not ignored.  My sleep times with my Charge 6 / iPhone 15 Pro Max have increased to awake 2-4 hours.  Sleep scores monthly this year averaged 82 - 83 and now with the increase in fake awake time they are daily "fair" to "poor".  I've used a Fitbit for years, starting with the Charge 3 and this is the worst change ever. Your phone lines are bombarded and first line tech wasn't told about the secret change and thus recommended meaningless troubleshooting steps I'm working directly now with an escalation supervisor in Bugaria via email who has been terrific and responsive. She confirmed the screams from angry users is growing daily.

So respectfully, what is currently being provided is useless and for some people a threat to their health. Sleep experts will tell you restless sleep is not the same as being awake and lumping it together is meaningless.

Suggest you read the posts and complaints under the Charge 6 category to see recent posts and anger over the change which was initially denied.

Thanks Fizzy. I appreciate the feedback.



(quick message from my phone)

Hi,

My sleep data appears to be back to normal and recording correctly.

I did check the heart setting and did a restart and then a short time later data for the previous night and all the previous sleep data reappeared.

Not sure what the issue was but now appears fixed.

[VNwalking]

Good to know, thanks @RiekocC.

Hey folks, 

I just reached Bali, Indonesia, three days ago, and ever since then, my Fitbit activity log timings (walking & sleeping times) have been showing incorrectly. Though the display time is working fine, the activity and sleep log times are showing 8 hours behind. 

I tried doing all possible settings changes, updates, restarts, etc., but the problem is not resolved. 

Any immediate answers shall be highly appreciated.

Thanks

new to me charge 6. been working fine for a week. sleep logging stopped 5am the night before last and nothing last night (yes heart rate monitor is on and fine).(SEE UPDATE BELOW!!!)

Decided to take the update so selected that on phone app and started it. But bar just goes from left to right continuously. I had expected a progress bar.  Is this correct? just let it sit?

activation date this year- Mar 10, charge 6, Pixel 7 current, fitbit app current. Restarted watch - no change.

- - - - -

UPDATE - I let it go 40 min and no change so I:
Restarted the phone /
Started fitbit app and clicked on top left icon, click on "Charge 6" and synced it (took a minute!!!) /
Checked data and sleep data was now there - lesson learned ! /
Started update and after a minute the icon with dots and a progress bar appeared on the watch. Lesson learned twice (not synced !)

Watch is now up and working (took maybe 5-10 min) and version changed from 66.20001.210.26 to ...214.24

Hi everybody!  I've merged all your posts here so that you all get the updates at the same time and to keep the Community in order. 
Thanks for letting us know that some of your sleep data was missing. We found and fixed a timezone issue that was causing sleep data to display incorrectly for some users.

Any missing sleep data should now be displayed correctly, but let us know if you're still having trouble.
