Fitness Trackers / Fitbit
Fitbit Charge 6 (2023)
The only Fitbit band with real GPS — but the best metrics are a $99.99/year rental.
Overall score 7.4/10
Pros
- + Genuine built-in GPS — the single spec that separates it from every other Fitbit band
- + Bluetooth heart-rate broadcast to treadmills, bikes and Peloton is rare at this price
- + Both S and L bands ship in the box rather than being a $30 upsell
- + ECG and EDA electrodes give it health hardware the cheaper bands physically lack
Cons
- − Daily Readiness Score and the useful half of the sleep analysis are Google Health Premium features — $99.99/year once the 3-month trial lapses, up from Fitbit Premium's old $79.99
- − The 7-day figure assumes always-on display and SpO2 both off; turn either on and Google itself says to expect less
- − A Google account is mandatory to set the tracker up at all
- − Proprietary charging cable that fits only Charge 5, Charge 6 and Luxe
- − Wrist optical HR degrades badly above ~150bpm — peer-reviewed testing found Fitbit units underestimate HR during intense intervals
Fitbit Charge 6 (2023) review: what the specs say
The only Fitbit band with real GPS — but the best metrics are a $99.99/year rental. At $159.95, Fitbit's 2023 model sits in the middle of the range — the fitness Trackers we compare run from $51.99 to $359. It scores 7.4/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Phone Independence at 8.5/10 — how much the device can do with the phone left at home — a real GPS chip and on-wrist readouts score high, connected-GPS screenless bands score low.. The weakest is Subscription Freedom at 5.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: daily Readiness Score and the useful half of the sleep analysis are Google Health Premium features — $99.99/year once the 3-month trial lapses, up from Fitbit Premium's old $79.99; and the 7-day figure assumes always-on display and SpO2 both off; turn either on and Google itself says to expect less. Every specification on this page comes from Fitbit's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

| Display | AMOLED colour touchscreen under Gorilla Glass 3, with optional always-on mode |

| What the Battery Claim Assumes | Google's 'up to 7 days' assumes the always-on display OFF and SpO2 off; the spec sheet states both 'will require more frequent charging'. Full charge takes ~2 hours |
