Charge 6 not syncing with the app

[bazingayed]

Everyday I have issues with the charge 6 and the app. It stopped syncing sometime yesterday (fitbit watch showed over 9000 steps the last sync showed 7000)

Today no steps, cant sync. Tried syncing on the PC, nope, on  the app , nope. Uninstalled and reinstalled the app..nope.  The watch shows my steps, but the app, and PC do not 

And this not syncing is a DAILY thing, I am just over this charge 6. 

I should have bought an apple watch argh

frustrating

Hi,
The sync worked for me after I rebooted my Pixel phone. This happened again
after some time and again got resolved by phone reboot.

Thank you,

I had the exact same issue.  When I clear my data on the charge 6, losing what was not synced, it is able to be paired again.  The app then asks me to use a "more secure Bluetooth connection" which is pairing with my phones Bluetooth just as any other Bluetooth device.  After doing this a couple of times, I unpaired the Bluetooth on my phone, just using the sync through the app, and have had no issues.  It still prompts me to connect with my phones Bluetooth, which I simply ignore and have full functionality.

Small update:  i found two Fitbit Charge 6 in the bluetooth devices list.   i think a new one got there after the update or something, because i never repaired my device.   after removing one of them it is working alot better

No solution has worked for me

I also get regular problems. Don’t know why they have changed the look either. The Fitbit was fine till Google took it over.

Ditto

Never had these problems with Fitbit. Since Google took it over it’s one problem after another. I can’t sync mine. Tried all suggestions and more. Of and by the way, I hate it’s new app look so bland and unappealing. Much preferred it prior to Google. All they have done is screwed it up.

Mine too. I have deleted the app, reinstalled it. Tried manually nothing. I am about ready to throw it away

I have had it happen twice but know the fix.  The support person helped in the Live Chat. Disconnect Bluetooth. Restart Charge 6 by going to Settings, Find Restart, Confirm Restart (will not erase data) Wait for Reboot. Reconnect Bluetooth 

Also can’t remember the exact steps, but connect Charge 6 to its power cable and then I think press both sides 3 times with a few seconds and do a  pause in between of each press.  It reboots.

Go to settings on Charge 6

Scroll to bottom of list

Press Reset device— This worked for me

Thanks but I have tried that numerous times, it doesn't work

I am having the same trouble. This is a brand new Charge 6. Every time I try to sync it takes forever. When I look at the device through the app it says there's no info. I tried resetting the device and everything else and I might just have to return this thing.

Well, I have similar issues, one time it syncs OK the other time it does not. Today Iam at HRV ZERO which is below my baseline 🙂

Is it time to find another device that is more consistent?

[pattycat59]

I finally got mine to work by resetting my Bluetooth. I was desperate, I
tried everything.

Charge 6 is won't even linking or syncing to my fitbit app.  It will link my phone but not my fitbit app.  I have tried troubleshoot, restart phone, delete bluetooth, app, restart my phone over and over again, and it won't sync to my fitbit.  I just replaced my charge 5 in June of 2025, when I received my charge 6 it worked fine, but the last two weeks I can charge my phone and sometimes it only shows like 300 steps all day but I haven't been able to look at my sleep...says no data.  Do I need to replace my charge 6?

Most horrible product this Charge 6.

Regret upgrading from charge 5

Return it if it is im warranty

[ChrisHut]

Me too

[Camunda]

I had to buy something because my Charge 5 broke. The metal casing on the back came off and then it was all downhill after that. Completely died a couple days later.

I was able to fix it last night by restarting my phone. We'll see how long that lasts.

[ChrisHut]

That’s very bad ! Considering how much they cost you should have got better.

I amnhaving the same problem, please advise.

Hi, what I found worked for me, delete the App and download it again.
Plug the charger in as if you were recharging then connect to your phone. On the charger at the plug end there is a circle on the connecting lead, press that and hold it down for 5 seconds. That should reset your device.
That is the only thing that worked for me. Good luck, I hope that works for you too.

[DoreeL]

Thank you. I will give it a try.
