Name: Fitbit Charge 6
Brand: Fitbit

My verdict

A light, water-rated band with built-in GPS and a 7-day battery claim. The workout tracking is where it slips: Coach found heart rate and GPS fell short, and TechGearLab scores it 56. I'd buy it for everyday wear and skip it if you train by the numbers.

What I like

28.3 g, per TechGearLab

5 ATM (50 m) water resistance, per TechGearLab

Built-in GPS, per TechGearLab

Heart-rate accuracy measured at 96.54% by TechGearLab

Coach lists long battery life as a pro

What annoys me

Coach found heart rate and GPS accuracy fell short in its workouts

Scored 56 in TechGearLab's table of 14 trackers

The 7-day battery figure is a claim, and no outlet I read measured it

1.04-inch screen, per Coach

TechGearLab doesn't explain how it got its heart-rate figure

I haven't worn a Charge 6. I'm working from two published tests: Coach's review from October 25, 2023, and TechGearLab's review and comparison table, updated August 13, 2025. The 6.2 is my opinion from those.

Every spec here comes through TechGearLab or Coach, not Google's own store page. So I can't tell you where the Charge 6 sits in Google's current line-up, what it replaced or when it came out.

Heart rate: the two tests don't agree

TechGearLab measured heart-rate accuracy at 96.54%. Its page doesn't say how it got there. No method, no reference device, no workout type.

Coach's reviewer went the other way and found that heart rate and GPS accuracy fell short in workouts. Coach gives no figures for that, though.

So I have one number with no method and one complaint with no number. Neither settles it. What tips me is that the tester who wore it through workouts didn't trust it, and that's the use where accuracy costs you something.

GPS

TechGearLab lists GPS as built in, which matters on a band this size: you can leave the phone at home on a run. Coach found the GPS accuracy fell short. No outlet I read published a distance or position error, so I can't tell you by how much. If pace and distance are why you're buying a tracker, that's a problem I'd want quantified before paying.

Battery

The 7 days is a claim. TechGearLab labels it "Claimed" in its own table and didn't measure it. Coach lists long battery life as a pro but prints no measured figure.

I found no test that ran the battery down. Treat the 7 days as Fitbit's number, not a result.

The ranking

TechGearLab gives the Charge 6 an overall score of 56 in a table of 14 trackers. That's one lab's scale. I'd want a second lab's score before calling it a bad tracker, but 56 doesn't make me reach for my wallet either.

Who I'd buy it for

Someone who wants a light band for daily wear. It's 28.3 g with a 5 ATM (50 m) rating, both per TechGearLab, and a claimed week between charges. If you mostly want to keep it on and glance at it, the workout complaints matter less.

Who should skip it

Anyone who trains by heart rate or runs by GPS pace. Coach's verdict on both is the main reason my score sits where it does, and I'd rather you spend the money on something a tester trusted mid-workout.

Also skip it if you want to read anything on your wrist. The screen is a 1.04-inch AMOLED touchscreen, per Coach. Small.

What I couldn't check

Coach's test is from October 2023, more than three years old now. TechGearLab's page was last updated in August 2025. I found no measured battery test, no published GPS error figure and no release date. I'll update this if a lab prints any of those.
