always-on display battery life (measured): 4-5 days · GPS track offset vs Pixel Watch 2 / Garmin FR955 reference (open trail): 3-4 meters

the improvements in the heart rate accuracy are real – be it via algorithm or new sensor, they definitely improved things there

Ok, so, the Charge 6 GPS is basically what we had last year with the Charge 5 last year – if it’s tight, you’ll lose GPS.

Unless worn at the absolute loosest level (hilariously loose), GPS simply won’t stay locked on.

measured weight (reviewer's scales): 30g · battery life in default mode (measured): up to six days · ECG reading failure rate in testing: about 50%

The Fitbit Charge 6 GPS suffers from serious connectivity issues if the strap is fastened too tightly, and the heart rate accuracy will take a hit from a looser fit.

the band tends to mess up quite badly in the first 5-10 minutes of a run before usually finding its feet, at least in consistent runs rather than interval sets

as ever, we find its sleep tracking reliability to be above average

Tom's Guide lab-tested · 2024-08-06

battery drop after one day without GPS: 15% · additional battery drop from a 30-minute GPS run: 10% · dead-to-full charge time: around two hours · sleep-stage vs Oura ring reference (awake time, two nights): 38 min (Fitbit) vs 36 min (Oura)

Overall, I found the Fitbit Charge 6 to be pretty accurate in most fitness tracking modes.

I was impressed to see the Charge 6 come up with pretty similar results, especially considering the tracker is a third of the price

At times, the GPS was slower to connect than it was on my Garmin
