I upgraded to the Venu 3 from the Venu Sq2 and I barely get credit for 300 calories from 15,000 steps. I compared the calorie graph on my watch to the heart rate graph and it looks like it's only giving me active calories for steps if my heart rate is 90 or above. My resting heart rate is 52 and my heart rate for normal walking is about 75. I didn't have this problem with the Venu Sq2.
