Not complaints — practical notes from owners that didn't affect the score.
“I also recently had Fitbit charge 6. I think they just give you a rough estimate. If it’s off by like 200-300 steps per day and you walked like 5k-10k, that’s still just a tiny percentage off of less than 4%.”— ACanThatCan on Reddit
“I observe my Charge 6 all the time, and have compared it to a good chest strap. (Polar) Most of the time they line up. Once and a while, the Fitbit goes ape. Jump rope can do it.”— HarpsichordGuy on Reddit
“I had a Fitbit Charge 6 before and that was more in line with the Garmin, so I think Apple isn’t that accurate for resting HR.”— honglong1976 on Reddit
“I am using the charge 6; the functions are pedometer and exercise tracker. You can sync it to display texts but I disabled that. I get four days comfortably between charges but it claims six.”— Ape_Face1985 on Reddit
“Even in yoga sculpt classes with high intensity bursts (burpees, etc) and I feel like my heart rate reaches a vigorous rate several times throughout the workout, I’m still only burning 300 calories according to my Fitbit charge 6.”— North_Cupcake_8694 on Reddit
“Put a gold band on it to make it look fancy. But also I noticed the origin silicone band caused rashes, this band prevents it.”— JediWebSurf on Reddit
“Fitbit charge 6 adv: ECG is an option, AFIB during sleep. Google Wallet. Cons, mic & speaker: if you want sleep score and stress score detail than you have to pay for sub”— jaamgans on Reddit
“I have a Fitbit Charge 6, and it definitely seems to measure HR more accurately when I have started a workout. I think that causes it to poll the heart rate sensor more agressively.”— tannenba on Reddit
