Similar issue. Upgraded to charge 6 from a 5. My morning jog/walk of 60 minutes used to get me 90 to 100 zone minutes now I only get about 65 or 70. Spend 15 minutes on rowing machine and get 10 zone. I’m 74. Frustrating. Doing same routines and getting 40 to 50% less credit.

@Docmassax The Charge 6 has a different heart rate algorithm that is supposed to be more accurate during exercise. Comparing the two devices is like comparing apples to oranges.
