I walked 3,300 steps with the Fitbit Charge 6 and Fitbit Charge 5 — here's the winner

Fitbit Charge 6 vs. Charge 5.

The Fitbit Charge 6 is the best fitness tracker for most folks in 2024, but what about its predecessor, the Fitbit Charge 5 which can often be found at a discounted price? The two devices look quite similar and share a lot of features and tech — here's a closer analysis of how they compare — the question is, which counts steps with better accuracy?

Both have an onboard GPS and accelerometer to keep tabs on location and movement and both provide a useful buffet of post-workout metrics, including pace, max and average heart rate, calories burned and of course, steps taken. 

Fitbit Charge 6 vs. Fitbit Charge 5 — step accuracy test

To find out how the Fitbit Charge 6 and Fitbit Charge 5 compare when it comes to step count accuracy, I strapped a device to either wrist — the Charge 6 on the left, the Charge 5 on the right — and set out on a lovely late afternoon walk around my neighborhood.  

As a control, I manually counted my steps for the walk's duration, clicking an old-school tally counter once for every one hundred steps taken. For distance, I used the Google Maps measuring tool post-walk, plugging in my exact route. 

After 3,300 steps — a third of my daily total goal — here's how the data captured from these two similar wearables compares:

Fitbit Charge 6 vs. Fitbit Charge 5 – the results

Both the Fitbit Charge 5 and 6 were within 25 steps of my actual total count. This doesn't surprise me all that much given Fitbit's reputation for accuracy in this department. However, the Charge 6 was six steps closer than the Charge 5, or just 19 paces over the total. 

Google Maps placed my total distance covered at 1.68 miles which makes the Charge 6 under by 0.15 miles and the Charge 5 over by nearly a quarter mile. The Charge 5 also seemed to think I walked at a faster pace than its sibling, despite taking roughly the same number of steps. 

While a speed of just over 18 minutes per mile from the Charge 5 seems too quick, 23 minutes and 37 seconds per mile from the Charge 6 strikes me as too slow. Which one is more correct? It's difficult to tell, but I do know that my standard walking pace tends to be between 20 and 21 minutes per mile. This is based on previous walk tests and my own experience tracking treks.

Moving on to heart rate and calories burned, both devices' metrics match up quite nicely, which is always encouraging to see.

Conclusion — Fitbit Charge 6 wins

For this head-to-head walk test, the laurel goes to the Fitbit Charge 6. It wins by the skin of its teeth — or exactly six paces — over its predecessor, the Fitbit Charge 5. It wins in distance accuracy by less than a tenth of a mile. 

Of course, this doesn't mean the Charge 5 is a stinker but it does mean that the Charge 6 is likely the better buy in most cases, even if it currently costs a little more than its older sibling.
