Heartrate readings too high compared to Charge 2

[5ggggg]

Since July I wear the versa on my left and the charge 2 on my right hand. Versa heartrate very often is up to 35% higher than what Charge2 measures.

I also measured the heartrate by hand with my watch and must say most of the time Charge2 is right.

- There is no difference if the activity is auto dedected or manually started

- There is no difference if I tighten up the strap. Of course if one weares it too loose it wont work

- Even if I wait until both show about the same value, versa often shows 5-10 beats more

As I wear them in parallel it would be a very good example for the Fitbit engineers to compare both.

Dear Mods / Fitbit devs / support ... Please analyse the following accounts !

Charge2: gggg2@wolke7.net

Versa:     ff0@vollbio.de

I also posted some examples here:

steps during cycling exercise and heartrate difference compared to charge2

If you are analysing the heartrate prob please also look into the prob that the versa very offten (like 20th-22nd Aug.) does not dedect my outdoor cycling (it seems related to how versa interprets bumps). The Charge 2 does !

Hello @5ggggg

Very good find. Hoping the developers see this and can make an adjustment on there next firmware download. 

I know this is not a really expensive medical device, but yours sounds like it's off quite a bit from the actual.

Fitbit does not seem to have any interest in investigating this problem ...
