Inspire 3 - Sleep tracker not working

[Camomille]

Hi Fitbit Support Team,

My Fitbit sleep tracker has stopped working properly since the beginning of October 2025. It records the start of my sleep, but if I wake up during the night, it stops tracking from that point instead of continuing for the rest of the night as it used to.

When I try to edit the sleep manually, no additional data appears.

I’ve already restarted the Fitbit, cleaned the tracker, and made sure it’s properly fitted on my wrist. Nothing has changed on my side, so it seems to be an internal issue.

Could someone from Fitbit please help me fix this? And if it can’t be resolved remotely, is there a way to send my Fitbit in for repair or replacement?

Thank you very much for your help.

I have the exact same issue with my Charge 6 since the Oct. 8 2025 update.  I frequently wake up during the night and I only get partial timelines that will not update after a manual edit of the sleep time.  I think this a software bug in the latest release.

I have the same issue.  It has worked to change the timeline and delete the shortest until yesterday, and now again today.  I have the Inspire 3.  The data is almost worthless, as is the scoring, because of this.

@ManuFitbit - Hi Manu,

Could you please check our query? We are a few to have the same issue.

Thank you

Now it is missing when I go to bed accurately by a couple of hours, and yes, it is still not transferring the data of the second sleep when I go through the routine I described above again today. Does anyone think changing the sensitivity to sleep will help.

[RichardRemmele]

I just had mine replaced by Amazon, but in setting it up, I noticed that
the phone app was updated on October 8th, the exact time when I started
having the problems. So, it is not the device but the phone app that is
causing everything to fail. Most of the sleep data is useless

[Mjolaughl]

The fitbit developers may think this is only an issue for a small percent of users, but it is this exactly this group of users that rely on the sleep tracking the most to make improvements in their sleep patterns.  I will be forced to get some other tracking device if Fitbit cannot fix this software bug.

[RichardRemmele]

I was going to get a RiingConn because it seems to have better sleep data according to my research, but I did a deep dive using AI, which gave me the whole background on the Fitbit and Sleep.  It turns out the most accurate sleep data with all of them split the sleep.  The more accurate they are, the wake time is less and less for the split to occur.  

The October release of Fitbit was a more accurate Logarithm, and the workaround to merge the sleep was never a thing with Fitbit.  It was a user workaround that just happened to work.  None of them allows, according to the AI search, a manual merging of the multiple sleep data.

What you can do is Snip the data from your phone using Phone Link to put the phone screen on your computer so you can Snip each and put them individually into Google Docs.  There are several ways to do it when you look it up on the internet, but not all work.  So, for example, you put the two Sleep Data images from your phone into Google Docs, and you click on one and do something called "break it," and then do the other or the rest, and then you can resize them and put them side by side.  I have done it once, and it is a work in progress for me, but it does work.  You can then snip the Google Doc outcome and put it into an email to yourself or do something else with it.

The bigger problem for me is the 3 or 4 hours of either first sleep or second sleep that it forgets about because it was not long enough to consider. Or I was awake too long for the sleep to be long enough to consider.  For me, the answer is to let Fitbit know when I went to bed and start tracking then, and when I wake up, and actually have the data for those parameters. Instead of it not keeping track at all if you do that.

[RichardRemmele]

One thing I have found helpful if you happen to use a CPAP, you can send your Fitbit data to your CPAP readout if you have Health Connect.  It can provide a more comprehensive reconciliation of your time spent in bed under the CPAP mask and the Sleep Data from Fitbit.  It also arranges the data in a slightly different way, which I found helpful.

Same issue on the Inspire 2, so confirming it is a software issue in the new software release in early October. 

Hello Google, when will this get addressed and fixed?!

[Mjolaughl]

I use the Snorelab app which gives me a good idea of when I sleep during the night.  I tried the CPAP and it did stop my snoring but I did not see more deep or rem sleep as I had hoped.

[Camomille]

From what I've gathered, you are correct. Unfortunately no coms from Fitbit or Google.

 Could anyone answer our messages please? @DHFitbit @JonFitbit @ManuFitbit @MarcoFitbit @EmsFitbit

Hi everyone and warm welcome to the new members. 

I appreciate all your messages and feedback, and I'm sorry to hear that you are experiencing this situation regarding the sleep tracking. 

Please let me suggest you to: 

• Offload the Fitbit app (iOS users). 
• Clear data and cache (Android users). 
• Confirm that your devices are syncing: How do Fitbit devices sync their data?

[mcboy2000]

Thanks MarioSFitbit.

Have done all those things to no avail. My device is syncing, just not accurately recording sleep time. When I manually edit, the sleep time adjusts, but the recorded sleep stages no longer adjust to reflect the corrected time.

In the past, offloading the IOS app and reinstalling did clear up some glitches, but not this time!

Any other suggestions?

Thank you @MarioSFitbit for getting back to us.

I have done all the previous advices about sync, clean the device, etc

Nothing is working. The device incorrectly record the sleep, and doesn't adjust properly the sleep after I edit it. 

Is it a system issue since most of us here have had the issue since the October software update? If so, could you please confirm when it will be fixed?

[RichardRemmele]

In addition to my post about Snip and Side By Side, I said that I got it to work, but it was a work in progress because it was a bit of trial and mostly error using Google Docs.  But I got it done, and somehow it set it as a default.  So I did my Snip and Paste into Gmail this morning, and when I did the one for the second sleep, it automatically put them side by side in the Gmail that I sent to myself.  So that was a bonus.  It is just one way of getting a better way to display the first and second sleep.

I am trying to track my sleep for health reasons as recommended by my Dr, so it would really be helpful if someone would help with this situation. The fact that nobody from Fitbit or Google has even responded is extremely frustrating!  Good luck to you and all of us having this issue.

Hi @MarioSFitbit. I have been having this exact same issue, is a software fix coming out for this? My phone will not sync to the fitbit after doing all the recommended steps and reinstalling, it is like Bluetooth doesn't exist on my device anymore. Some other suggestions recommended doing something to Bluetooth settings on actual fitbit but this doesn't seem to exist. I have been quite active recently and am disappointed I cannot track this on the app
