I've owned numerous Fitbits and still have all of my data from back to 2016! Nothing else but Fitbit devices. But about two weeks ago the sleep metrics and all of my older data all started to change, big-time. I noticed right away because keeping track of my activity along with sleep is a big deal and is the main reason I have been loyal to Fitbit this whole time.
It's as if someone clicked sleep to 'Sensitive' Mode over normal mode. I am getting around 35 minutes less per night now. And when I try to correct my times it rarely gives me anything extra. Just as if I am in sensitive mode (which I tried out one time a couple of years ago).
But the biggest sign of this being a Fitbit metric issue rather than a faulty device is because all of my PAST SLEEP DATA has now changed significantly. Again, I have data for every year going back to 2016. My sleep average for the last whole year of 2024 was 8 hours 13 minutes. In 2023 it was 8 hours 15 minutes. 2024 sleep average for the year NOW is 7 hours 40 minutes. And for the year 2023 is 7 hours 45 minutes average. Same thing with ALL years going back to 2016.
I'd just like to know if there is anything I can do about it, and, perhaps why Fitbit designers made this change?
Also, I own 3 different Sense 2 devices and tried using all three within the past 2 weeks. Exact same thing with all three so I know it's not a faulty device.
I also tried resetting sleep setting from normal mode, to sensitive mode, back to normal and still no difference.
The fact it has affected all of my old sleep times, 8 years back, suggest this is a new shift in algorithms by Fitbit designers. At least that's all I can surmise from all of this. Any help or information would be greatly appreciated. I'd like to get back to how it was which was very accurate. It is not accurate now. And I do rely on this information significantly on how I plan my days and weeks. And, again, has changed all of my times in all of my eight years of history. I do have some screenshots if wanted. Thanks so much!
