Fitbit Charge 6

Battery life and charging

Fitbit claims up to 7 days and a 2-hour charge. Real use is closer to the middle of that range: PCMag measured 4.5 days of normal use (22% drain per 24 hours) and 3 days with the always-on display at maximum brightness, while Wareable saw about 15–20% a day, or roughly 5 days. Consumer Reports lab-tested 206 hours under typical daily use, about 8.6 days, with a 97-minute full charge. The charging cable is the same proprietary USB-A cable as the Charge 5, so an old one will do.

GPS is what drains the battery fastest. Wareable measured a 30-minute outdoor run at about 30% drain with onboard GPS against 7% with connected GPS, and one owner reports a 4-hour GPS hike eating about 70% of the charge.

GPS and workout tracking

The onboard GPS is the weak point across independent testing. Dynamic GPS can drop back to accelerometer tracking mid-workout. The practical workaround is Dynamic or Connected GPS, which leans on your phone.

Heart rate is a different story. PCMag measured up to 40 seconds slower than a chest strap or an Apple Watch Series 9 to register peak heart rate after maximum sprints, but the averages tracked well, and the Charge 6 broadcasts heart rate to gym equipment like treadmills, rowers and Peloton. There is no altimeter, so hill routes and floors-climbed are not reliable.

Subscriptions and running costs

The band is the cheap part; the subscriptions are the ownership cost. Fitbit Premium runs $10 a month and gates the Daily Readiness Score plus detailed sleep and stress insights after the 6-month trial. YouTube Music Premium runs $10.99 a month and is the only on-wrist music control, with no offline storage. CNET puts the two together at about $21 a month once the trials end. Legacy Fitbit accounts also have to migrate to a Google Account, and Google Maps on the wrist needs your phone in Bluetooth range.

Wear, repairs and warranty

Fitbit’s US warranty runs 1 year from purchase, and EEA buyers get 2 years. Liquid damage voids it, and dust and water resistance fade with normal wear, so dry the band after it gets wet. Only Google or a Google-authorized provider should repair a Charge 6, and there are no user-serviceable parts; Google sells replacement bands and chargers. Charge 5 bands and the charging cable fit. Band durability is a recurring complaint: Wareable’s test strap broke after 2 days, and r/fitbit threads mention band wear. Some Charge 6 bands are not water resistant.

Is it worth it?

Google Store lists the Charge 6 at $159.95. PCMag found it at $134 (Walmart) and $159 (Best Buy) in October 2023; Tom’s Guide saw $139 in June 2025, and Wirecutter tracked an $80 sale and a $104 Walmart price in 2026. Under about $120 the heart-rate and sleep tracking plus the battery make it easy to recommend; at full list price the flaky GPS and the subscription stack are harder to justify. If you mainly want GPS and music on the wrist, a watch is the better spend.

Which model this is

This is the sixth-generation Charge, released in September 2023, sold in Obsidian/Black, Porcelain/Silver and Coral/Champagne Gold. Don’t confuse it with the Charge 5, which shares the 1.04-inch AMOLED display, GPS and sensors; the Charge 6 adds a haptic side button, Google apps and heart-rate broadcast to gym equipment. Charge 5 bands and the charging cable are compatible.

The Amazon listing for this model is ASIN B0CHN3P8DW.
