I know. I just got done chatting with them and the representative told me he knows nothing about it and does not know when the next firmware update is going to come out and if it will even fix it. This tracker Is going back
Its my second one. It is effecting a lot of them. If you search the Internet and this forum you will see the heart rate is not good. Versa 2 and charge 2 Were much more reliable and accurate. For $300 I expect it to be at least as accurate as the older models

As far as I can see the issue is not sporadic but affecting every device. It also appears to be software related rather than hardware so hopefully an eventual properly done update could solve it.
Same issue. My heart rate is way lower than what registers on my other devices during intense workouts. I have to stop moving then about a minute later, my heart rate stabalizes and become inline with my galaxy watch. I have a Charge 3 that is also much more accurate during intense workouts. I don't want to return the watch however I do intense heart rate training and I need accurate data.
Mines fine at walking speed but jumps up to 140 at a lite jog where my polar h10 is reading 103. Please fix this fitbit!!!!
Best AnswerHow could I get 38 zone minutes with a max HR of 68? In 11 hours. I must tell my ♡ doc it isn't helpful. I hope the arrhythemia study Fitbit is doing illuminates some of our issues...

A fun experiment I'm testing, for when the watch is not displaying a reasonable heart rate value.
To set it up, it requires temporarily setting the screen time out to 60 seconds and switching to the Today app to see heart rate.
Then when you have an incorrect reading slide a piece of paper between the watch and wrist to block heart rate detection.
The value quickly turns to --.
Leave it there for a while then raise your wrist to start the screen viewing timeout and remove the piece of paper.
After around 10-15 seconds you get a reasonable heart rate value displayed, which may last for a short while if you don't move.
You might like to see your watch actually working correctly!!
Have not yet perfected the experiment.

Best AnswerActivity's graph is showing heart rate every few seconds or every second while the daily graph is showing average heart rate with intervals of 5 minutes.
In the daily one you will not see spikes of 1-2 minutes or less.
Best AnswerI found this thread via a Google search & I'm glad to know that I'm not the only one.
It seems to do fine when I'm not active, but falls all apart when I am.
From today:

There's just no way that my HR was higher during a my ten minute Yin yoga cool down than when I was crushing myself on the elliptical.
(The elliptical's hand sensors - which I admittedly don't usually consider terribly accurate - consistently had my HR at between 145 and 160 and that seemed much more on point than what my new $200+ smart watch was saying.)
I'm pretty annoyed.
I do about more searching before returning this, though - if it's a software issue, I'm willing to stick it out for a bit, but if the hardware's shot then I can just say that I'm glad that I got my Sense at Costco.
Best AnswerAfter 6 years I traded in my fitbit for a Garmin Forerunner 945 and I love it. It was more expensive but was it really? I don't have to pay for a premium subscription and the thing actually works.
I may have hung in with Fitbit, but like yourself, their failure to acknowledge a problem is what chased me away. The BS answers customer support gives is disheartening.
The fitbit sense was the greatest marketing device for Garmin I've ever seen.
Best AnswerHas anyone received a replacement and the issue is now resolved?
Basically having the same issue as everyone else, seems to track fine for jogging... but for weightlifting, crossfit, etc., it's way off.
I've cross tested this with other HR monitors, and wore my gf's Versa as well.
Best AnswerGot my sense 1 week ago. 4th workout lifting and I barely get over 100 bpm. Previously used the charge 3 and my max hb used to be 156 with average about 125-130. The sense is max 130 with average around 100 and a lot less cals burnt per workout. Disappointing- this is supposed to be their flagship product!
One can only assume that it must be a big problem if they won’t even acknowledge that it’s a problem on their side. Once they admit it’s a problem then the clock starts ticking for how long it takes them to fix it. The longer they take to acknowledge the problem gives gives them more time to fix it without scrutiny. For me I went and bought an Apple Watch. I strongly dislike having to charge the Apple Watch every day but let me tell you something the data is legitimate.
