@allan473   The Charge 5 Features/Specs page says it has PurePulse, not PurePulse 2.0.  I'm sure you will never get a complete, satisfactory answer about the advantage of one version compared to the other.  It is proprietary information.  My only suggestion is to search the tech sites where someone (not a Fitbit employee) might have made a comparison.

Here is an article from TechAdvisor that makes the claim that the Charge 5 in fact uses the newer PurePulse 2.0. Check out the link below ...

@Stev12   In this case, I would believe the Fitbit's Specs page over TechAdvisor.  The optical heart rate monitor emitter/sensor component is very different between the Sense/Versa 3 and the Charge 5.  The Sense/Versa 3 (Purepulse 2.0) OHR monitor has two emitters.  The Charge 5 has one.  The Charge 5 and the Luxe have the same OHR monitor.

The Fitbit Specs page isn't error free.  I will give you that.  I think TechAdvisor got this one wrong.
