Owners are genuinely split on the Charge 6. Fans love the slim, sleep-on-it comfort, weeklong battery, low price, and heart-rate readings that match chest straps and cuffs. But a large share report the opposite experience: erratic heart rate (spikes to 150-211 bpm at rest, sometimes double the real rate), phantom or double-counted steps, weak running GPS, and an app that's gotten worse since Google's takeover, with some features (floors, goals) removed and others locked behind Premium. The most damaging complaints are hardware: black screens and dead units within months, and water damage killing devices despite the swim rating.

“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%.”

“I highly recommend a Fitbit Charge 6 for sleep tracking (and steps). I don't really care about the actual sleep score it calculates, all I want to know is the tendancy of that score”
