I can't connect my Charge 6 to my iPhone

[Viktoriiiia]

I can't connect my fitbit charge 6 to my IPhone. I tried everything in the manual and on the internet, but it just keeps giving me an error when I connect it. I am very upset that nothing works, I spent a lot of money on this watch. I think it's unfair and not fair to people, and it doesn't inspire confidence in manufacturers and in Google, I think people should be responsible and correct their mistakes. I can't return the watch to the store because the warranty has already expired, which is a shame because I hardly used it.

Welcome to the community forums @Viktoriiiia. 

Thank you for sharing with me this feedback and the experience that you have using the Charge 6. Thank you for trying to fix it on your own and sorry to know all the difficulties.

Please, let me know what kind of error you see on the screen.

In the meantime, take a look at the points listed in this help article: Why can't I set up my Fitbit device?

Same problem. If it’s anything like mine, it’s a nondescript error “Something went wrong an error occurred, please try again” so no code or anything that could be helpful.
I’ve had my charge 6 since 5/1/25 and it wouldn’t sync today no matter how many times I tried. I followed ALL of the troubleshooting issues -phone restart, app reinstall, watch restart, etc and after doing the “forget this device” it now absolutely will not pair- I’ve set up many fitbits in the 10 years I’ve supported Fitbit so I know to have it plugged in, Bluetooth on, and nearby, but it keeps saying there’s an error. 
I debated switching to Apple Watch after my versa 4 broke 14 months into owning it (shortest lifespan for any Fitbit I had owned), and I now wish I would have.  
I am currently in a StepBet and if I cannot get this resolved and synced in a timely manner, will lose money (even more than I apparently wasted on this subpar product) despite having actually taken the steps and to no fault of my own. Super not impressed.

Hello, thank you for answering. I see on the screen “Something went wrong an error occurred, please try again” and I have already tried many times everything in this help article. 
The first problem I had after arriving in another country was that I couldn't synchronise the time zone, then the watch stopped measuring sleep. I tried to reconnect everything, but unfortunately I couldn't, and this error keeps appearing.

Hi, I understand how you feel, I have exactly the same unpleasant situation. Thanks for sharing, I still hope they will fix it because you can't take money and not provide a service and this is not a small unknown company - a thief, my trust in Google has not yet died )

For the something that went wrong. 

• Stop the app (on android, due this through the phone settings.)
• Clear the cache. 
• Remove the tracker from your phones BT. 
• Try the setup

Thanks for the instructions, I have already done that and it didn't work

I have tried everything suggested several times still not connecting. Now the only thingI get on my charge 6 is download the fitbit app so I once again uninstalled the app and reinstalled it still nothing  Now that is all the device does. This charge 6 was purchased on february 2025 how do I get a replacement?

Same! I’ve had mine for a while and it’s worked up until now!

SAME SAME!!!

Was having much the same problem. What worked for me was to got into settings on your IPhone, then Apps and find the fitbit app. Go to the 'bluetooth' line in the fitbit app and toggle it off for a little while (10 secs or so). Turn it back on and then open the fitbit app on your phone and try pairing your fitbit device again.

Don't understand it but it worked. Turning bluetooth off and on for the phone itself doesn't do it. You have to go into settings of the fitbit app.

Hello @retamajor 

For the replacement process, start by contacting Support (<-- click). Complete the prompt in Step 1. Tap Continue in Step 2 (ignore Resources) to get to Step 3 which has the contact options.

I talked with google support and they walked me through reinstalling my
Fitbit as if it was new and it worked perfectly. Thanks
