Which fitness tracker brand is the most reliable?
Unique Which? reliability data can help you to choose a durable fitness tracker. We survey owners of a wide range of brands, including Fitbit, Garmin, Huawei and Xiaomi, to reveal which lasts longest
We asked more than 18,067 people, including Which? members and members of the general public, to tell us whether they're happy with their tech products. In our unique longevity survey, we questioned fitness trackers owners with 2,962 devices to see if they've experienced any problems – so you can see which brands are worth investing in.
Fitbit is a brand that's synonymous with fitness trackers. But you might not be left thrilled by its long-term performance as it was the brand most likely to develop faults in the six-year period covered by our survey.
The most commonly reported problems for Fitbits were straps breaking, batteries getting drastically worse over time, and devices no longer syncing with their linked smartphone.
In fact, of all the tech products we surveyed, fitness trackers were the most likely to develop a fault. Some 20% of fitness tracker owners told us that their product developed a fault within six years and 16% within just three years, so it's important to choose a reliable brand.

How we calculate the best and worst fitness tracker brands
Which? has a wealth of information on Britain's favourite brands. Every year we ask Which? members to tell us about the tech they own – from how likely they'd be to recommend a brand, to how reliable the products are once they get them home.
This year, 18,067 Which? members and members of the public told us about more than 61,577 individual products.
- We calculate our customer score based on whether customers would recommend each brand and their level of satisfaction.
- We also calculate which brand developed the most faults, based on how many faults each brand developed up to six years old.
Our surveys, combined with our extensive lab tests, mean that we can recommend the best tracker to buy. Find out more about how we test fitness trackers.
When choosing one, it's also important to consider security support periods. Find out which fitness tracker brands are open about their security support periods.
