Fitness wristband for daily health tracking

The Fitbit Charge 2 is a wrist-worn activity tracker built for people who want continuous insight into their movement, heart rhythm and sleep patterns without wearing a bulky smartwatch. It suits users who prefer a dedicated fitness band that stays on the wrist day and night.

Behaviour during extended wear

PurePulse optical heart-rate monitoring runs continuously, delivering resting-rate trends and simplified zone data throughout exercise sessions and normal daily activity. Automatic SmartTrack detection records walks, runs and other movements without manual start presses, while all-day step, distance and calorie counts accumulate in the background.

Build and everyday fit

The Large band fits wrists measuring 6.7–8.1 inches and fastens with a classic clasp that stays secure during workouts and sleep. A blue elastomer strap resists sweat and water exposure from hand-washing or rain, and the vertical OLED display remains legible in indoor and outdoor light for quick stat glances.

Questions about this item

How much power does the Charge 2 consume during all-day heart-rate tracking?

The tracker runs for up to five days on a single charge, so daily power draw is very low and produces no noticeable heat on the wrist.

What smartphone and app are required to set up and sync the Charge 2?

You need a compatible iOS or Android phone with the free Fitbit app installed and Bluetooth enabled for initial pairing and ongoing data sync.

Will the Large 6.7–8.1 inch band fit the same charger and accessories as my original Charge?

No, the Charge 2 uses a different charging cable and band design, so earlier Charge accessories are not interchangeable with this model.
