Why No. 1 beats No. 2
The Xiaomi Smart Band 10 (8.8) beats the Google Fitbit Air (8.5) because it leaves owners clearly happier. No. 2 is the newer design, but not by enough to close the gap.
About the Xiaomi Smart Band 10
The Smart Band 10 is a pill-shaped band with a 1.72in AMOLED touchscreen at 212 x 520 pixels, a 60Hz refresh rate and a 1,500 nit high-brightness mode. The body is about 22.5 x 46.4 x 11.7mm and weighs 15.95g without the strap. It uses a quick-release strap system, and Xiaomi sells extra strap designs.
Inside are an optical heart rate sensor, a pulse oximeter, an accelerometer, a gyroscope, an electronic compass and an ambient light sensor. It tracks sleep, stress and more than 150 sport modes. It is rated 5ATM (50m) for swimming. A reviewer at Gadgets & Wearables noted that heart rate can now be read underwater, and that swim tracking improved with the new compass.
There is no GPS in the band. It borrows your phone's GPS for outdoor runs and rides, so the phone has to come along. In that review, distances came out slightly shorter than a Garmin Forerunner 955 on both runs. Everything is read in Xiaomi's Mi Fitness app, which works with Android 8.0 and above and iOS 14.0 and above over Bluetooth 5.4.
Battery is a 233mAh cell with magnetic charging, about an hour for a full charge. Xiaomi quotes up to 21 days in typical use, about 9 days with the always-on display on, and about 8 days under heavy use. After a week of heavy tracking, with one-minute heart rate sampling, sleep and stress tracking and a couple of workouts, the Gadgets & Wearables reviewer still had about 70% left.
What owners report about the Xiaomi Smart Band 10
Owner feedback for this model is limited, mostly short comments rather than long-term reports. Battery gets the warmest words. One owner who came from the Band 9 finds power use steadier on this one, and another calls the battery life excellent. A third needs a top-up to about half roughly once a week.
The strap draws the most complaints. A few owners say the clasp or loop has come undone, and one says the band fell off and chipped. Another got it to stay shut by fitting the strap the other way round.
The software is the other weak spot. One iPhone owner says steps do not show up in Apple Health despite granting permissions. Another reports the band dropping its connection, leaving the app's data fields empty. A third calls Mi Fitness the weak link of Xiaomi's bands. Others did not raise these problems.
Who the Xiaomi Smart Band 10 suits
It suits first-time tracker buyers, casual walkers and swimmers, and anyone who wants a large bright screen and about a fortnight or more between charges. It works with both iPhone and Android. Reviewers found workout heart rate close to a chest strap, though the page notes interval accuracy is not perfect.
Look elsewhere if you run or ride without your phone: Amazfit Bip 6, Fitbit Charge 6 and HUAWEI Band 11 Pro have built-in GPS. If you dislike a screen on your wrist, Garmin Cirqa and Polar Loop have none. Keep the always-on display off if battery matters most. Serious runners may find the app thin on detail.

The other badge winners in our fitness trackers ranking.
Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 16 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
