Fitbit Charge 6 – Sync/Pairing Broken Since June 8, 2025 (Device Unusable, Support Unresponsive)

[ShellarI]

Summary

Since June 8, 2025, my Fitbit Charge 6 has been unable to sync properly or pair completely. I’ve followed every step in the official troubleshooting guide multiple times, tested it on multiple phones with different Android versions (9a, 7a with Android 16, 5a with Android 14), performed full resets, reinstalled the app, cleared Bluetooth and app cache, and more.

The only partial result: step count and sometimes heart rate syncs occasionally, but pairing never completes — and the app remains stuck in a limbo state, asking to “Finish Setup”. Attempts to pair show the 4-digit code on the device, I enter it, and after a long delay it fails with an unspecified error.

Support Timeline

On June 10, after trying everything myself, I contacted support.

I spent over an hour in live chat, repeating all the steps. Support confirmed they pulled logs from my device and escalated the case.

Since then, I’ve only received automated or irrelevant responses, such as “how to change the clock face” or “how to pin stats to the dashboard”, which completely ignore the sync/pairing issue.

Every 48 hours or so, I get a vague message like "we’re working on it", but no technical update, no confirmation the issue is reproducible, and no help on how to save the data still stored on the device.

Why It Matters

I am currently recovering from surgery, and tracking vitals like heart rate, stress, and HRV is critical.

Fitbit warns that data not synced for 7+ days may be lost, and we are already past that point.

I paid for a premium product and service — but right now, the tracker is functionally a brick and Fitbit support seems unable or unwilling to help.

What I Need

A clear and functional fix for the pairing/sync issue.

A way to manually extract data from the device if syncing isn’t possible.

An honest update — even if the problem is known and being worked on, say it. Don’t send copy-paste replies that pretend everything is fine.

If you’re affected too — please comment below or tag the thread. It’s clearly not an isolated issue.

Seem to behaving same problem since last update can no longer sync phone to the watch.

Now when tap on fitbit app won't recognise email or anything YET it sends weekly email and some details...WTF

Same issue here since June 8. Support spent over three full weeks giving copy-pasted basic steps that didn’t apply, despite logs and screenshots.

Only now they admitted there are no further troubleshooting steps — and the only option is factory reset, which wipes all data.

They also ignored that I’m a Premium subscriber and was tracking critical post-op recovery data.

This is beyond frustrating — it’s negligent.

How can they still be selling this device?

Update (July 2):

After 24 days of back-and-forth, Fitbit support officially admitted they have no other troubleshooting steps to offer. Their only suggestion now is a factory reset, which will erase all device data.

Worth noting: I could have done that on day one — if they had been transparent.

Instead, they kept me going in circles with scripted steps for over 3 weeks, resulting in the loss of all recovery data from June 9 to July 2, which was especially critical for me after surgery. I’m a Premium subscriber — the service provided was unacceptable.

Looks like support just simulated activity, and only now escalated the issue, which got dismissed with “reset it.”

That’s not support — that’s damage control, at my expense.

I think the same as my problem, resetting won't help you. By the way, it's already the 5th working day since I've been waiting for a response to my case by email

Yep, the latest software update broke it.  I had to get a Charge 6 because my perfectly good Charge 5 was broken by a software update (this happened to every Charge 5 owner).  Google is hellbent on destroying their Fitbit product.

What software update do you think might be the problem? I'm on App version 4.46. 

Fitbit charge 6 is still working but no data on the app since June 16th. Partial sync on June 25th. I've been through all of the steps many times and now having unpaired my device from my phone i can't get it to pair again. Very frustrating. 

[ShellarI]

Looks like in my case the issue started right after my Pixel received Android 16 (which is... Google’s own OS), so it seems the Fitbit team (also Google) was completely unprepared for changes introduced by their own colleagues in the Bluetooth or sync stack.

The fact they still haven’t acknowledged this or provided a fix weeks later tells a lot.

If you're also on Android 16, that's likely the root cause.

I’m having the same issue for almost a week now I haven’t even seen an actual app update on this app for months so I don’t know what’s going on.
