Comparing Flex 2 to Charge 3

[donalduck]

Hi, I upgraded from Flex 2 to Charge 3 for its greater sleep management tools. But I am having trouble reconciling my stats from Flex 2 with Charge 3. For some reason the number of awake minutes are much greater for Charge 3. As an experiment I wore both Flex 2 and Charge 3 together for one night. My Flex 2 recorded 7 hrs 52 minutes of sleep with only 9 minutes of awake/restless time. My Charge 3 recorded 6 hrs 50 minutes of sleep with 1 hr 22 minutes of awake time. Don't minutes of awake time mean the same thing for both Flex 2 and Charge 3?

@donalduck.. hey there and yes they do. the reason in difference is the HR factor. your flex just knows you aren't moving. your HR knows you are at a resting HR for an extended period of time. I would trust the data of your C3 over the flex.
