Inaccurate sleep on Charge 6

[Copland]

Did something change with the sleep tracking on the Charge 6 on or about 23 June 2025.  While I used to have sleep scores consistently above 80 with 8 hours sleep, since that date my scores are between 66 and 74 and it shows sleep times between 6 or 7 hours every day (I would occasionally get these sort of sleep scores previously but only if i had a bad nights sleep).  Personally, I have not noticed any change in my actual sleep patterns.  I have reinstalled my app and restarted my Fitbit and Bluetooth.  I have not changed the way I sleep or how I wear the Fitbit. Is there a setting I need to change?  Or was there an update that changed the way sleep scores are calculated. Thx

I spoke to Fitbit Support again regarding the inaccurate sleep issues on the charge 6 – they could not help but the Fitbit Customer Care Team advised by email afterwards…..Thanks for letting us know about this issue. We’re aware of it and are working to identify a resolution as quickly as possible.

Could our community leaders @StephanieFitbit  @CrisVillaFitbit  or @JuanFitbit confirm this and perhaps elaborate further.

@Copland (Base Runner)  Thank you for staying on this.  I hope FitBit fixes it.

THANKS very much for your persistence and telling us that they actually know about it and are working on it. Yay!

Same here... i do not like the new scores. Please Fitbit go back. When you look at your score, it is really depressing.

These changes are terrible. Said I was awake for three hours the other night. I don't believe they are working on fixing anything. Everything Google touches gets ruined. If they really cared about their fitbit users, they would return the sleep algorithm to its previous, more accurate version. If they are trying to push fitbit users to go to Google products, I  can guarantee i won't be one of them.

re: "Everything Google touches gets ruined."

I disagree. Gemini, their AI (not just the browser-mode option) outranks all others in recent tests with results published in the NY Times or Washington Post. Anthropic's Claude is the contender, not ChatGPT. Their security and spam filtering are excellent, their routers are good and even attractive designs. They constantly innovate, and you can actually reach a real person for tech support in the rare instances that you need help.

I've had Fitbits since the Flex (2013). Google has definitely improved it since they bought Fitbit (which was in decline).

I intensely dislike their push to move everyone to watches, but that's no different from the push to move everyone to apps rather than web access using a real computer. I tried a watch, another brand, and do not like them at all. So, like others here, I hope they'll at least continue to update and support their two best-selling Fitbit models: Inspire (best-ever model) and Charge. I'll bet they'll announce a Charge 7 by October 2025, latest. If that doesn't happen, then....

It’s ridiculous what they’ve done!  I was wondering what happened because I know my sleep is the same as it’s always been.  Now I am consistently in the “poor” range but I know that is not true.  Why do they “fix” something that is not broken???  It was fine before.  Some engineer needed something to do at work so they let them screw up a program that was working fine.  🤬

Last night, it said I slept 5 hours and 58 minutes - sleep score 66!!!  Said I was awake for 3 hr and 34 minutes - rem sleep was 42 minutes and deep sleep was 48 minutes.  No way!   But I know for a fact that this is bogus and not correct.  🫤

Absolutely correct.
