Fitbit Charge 2chat_bubble_outlineFrom real comments

Many long-term owners praise the Charge 2's durability and simplicity. Several users report keeping their Charge 2 for years — one for over six years, another for four years, another bought a second one after their first still worked in 2017. Commenters value the easy-access button, step and move reminders that motivated lifestyle changes, and straightforward interface compared to smarter, more complex watches like the Apple Watch.

Heart rate and floor-climbed accuracy are common complaints. Multiple users report heart rate readings far off during intense exercise, in one case showing 90 bpm instead of an actual 170. Floors climbed relies on air pressure and is easily thrown off by wind, sometimes registering absurd numbers like 60 floors from a short walk, undermining trust in the device's fitness metrics.

Battery life, screen durability and lack of water resistance frustrate some owners. Reports vary from batteries dying after 8 months to lasting years, with several successful DIY battery replacements described as fiddly but doable. Others report screens cracking or scratching easily, bands bubbling or causing rashes, and disappointment that the device isn't waterproof for swimming or heavy workouts in the rain.
