Xiaomi Smart Band 9 Active: One-minute review
Writing this Xiaomi Smart Band 9 Active review, I wasn’t exactly expecting it to hit our list of the best fitness trackers on the market — it’s startlingly cheap, designed for people who just need the fundamentals of health tracking. However I wasn’t expecting it to miss the mark so much.
Released as an even-more-affordable alternative to the already-affordable Xiaomi Smart Band 9, the Active model cuts the cost, as well as some corners, from that predecessor. However, it cuts so many corners that, like a really bad lapidarist, it leaves nothing left to appreciate.
Testing a cheap fitness tracker like this, you have to expect some compromises, but the Band 9 Active takes it too far. Many different health tracking metrics were easily proven wrong, with GPS reading poorly compared to data from our smartphone and heart rate information being laughably inaccurate. Calorie burn predictions were also dubious, unless I truly did only burn double-figure calories in an hour-long weights session.
One surprise exception was sleep tracking, which to me seemed vaguely reliable — at least, compared to distance or heart rate. If you just want a cheap and feature-sparse sleep tracker, this could be a valuable option.
Still, the Xiaomi Smart Band 9 Active really struggles to prove itself as a useful health tracker given how ropey the testing results were. It fares a little better with its ‘smartwatch’ lifestyle functions as it was quick to send through notifications and let you control music.
It’s par for the course for fitness trackers to opt for offering a range of features, with the Xiaomi Smart Band 9 Active trying to track loads of metrics and health considerations. However, it seems that Xiaomi’s focus on breadth over depth has resulted in a wearable that’s hard to recommend. If you want a fitness tracker that has all the good bits of the Band 9 Active and few of the issues, opt for the standard model or the bigger and pricier Xiaomi Smart Band 9 Pro.

Xiaomi Smart Band 9 Active: Price and availability
- Costs $44.99 / £19.99 / AU$42.99
- Cheaper alternative to Band 9
- Released in October 2024
The Xiaomi Smart Band 9 Active was unveiled in China in October 2024, alongside the Band 9 Pro, and was slowly rolled out globally over the subsequent months. It’s now available to buy in most countries globally including the US, UK and Australia.
You can buy the Band 9 Active for $44.99 / £19.99 / AU$42.99, so it’s an incredibly cheap fitness tracker — though you don’t need to know currency conversions to know that some folks get it cheaper than others. I found some significant price fluctuations on Amazon, with Australian shoppers on the retailer getting a variation of a few dollars depending on the color option, and UK buyers being shown prices literally twice as high as on Xiaomi’s own website! So shop around to find the best price.
That’s a roughly $15 / £15 / AU$20 drop in price compared to the Xiaomi Band 9, a healthy discount that means that the budget band will likely undercut the original one even when the middle child is on sale. The cost also roughly matches the Xiaomi Band 8 Active from last year.
There aren’t many cheap fitness trackers at this price bracket that bear mentioning, so the Active’s competitors are all (relatively) pricey alternatives like the other Smart Band 9 models and options from Samsung and Fitbit if you can find them reduced. More on competition later.
Xiaomi Smart Band 9 Active: Design
- Display doesn’t look great
- Rectangular body plus strap
- Fairly well protected against bumps and water
The Xiaomi Smart Band 9 Active has a pretty utilitarian design. Its body measures 4.6 x 2.7 x 1cm and weighs 16.5g, so it’s pretty small, and it totes a 1.47-inch display with a 172 x 320 resolution.
The band is made of TPU, which feels like a rubbery plastic, and can be adjusted for a wide range of wrist sizes. You can pick up the Active in black, beige or light pink, and your choice is reflected in the band’s body and strap.
With a 5ATM water resistance, the watch can withstand submersion in water at up to 50 meters — however, there are no swim tracking modes on the band, making this a feature you won’t need to test.
I bumped and bashed the Band 9 Active a fair few times during testing and it didn’t show a mark — it’s a good pick for clumsy wearers. It’s also small enough that you can wear it to bed without it being too noticeable and annoying.
The display, frankly, doesn’t look great, but that’s what you’re getting for your low entry fee. You can put your own photos as your watchface too which is a nice touch, even if faces end up looking a little like old-school RuneScape characters.
Xiaomi Smart Band 9 Active: Performance
- Many metrics seem inaccurate
- Poor at pulling data from smartphone for GPS
- 50 sports tracking modes in all
The Xiaomi Smart Band 9 offers about 50 different fitness tracking modes, roughly a third as many as its two siblings though all the basics are covered (and then a few). Before you remark about how many that is, bear in mind that not all fitness tracking modes are equal.
Basically all of the fitness modes track time and heart rate, and some throw GPS in on top — the reason you’d pick between different tracking modes is so it’ll show up as a different entry in your fitness log, and because you can set different workout goals for different activities.
For testing purposes I used outdoor running, outdoor cycling and strength, but the fill list includes everything from badminton and baseball to billiards and ‘back’ (back workouts, that is).
Unfortunately, they’re not great: most of the Xiaomi Smart Band 9 Active’s fitness tracking features don’t work as they’re supposed to.
Here’s an example: one testing day I ran to my gym, which is usually 1.6km but the ‘outdoor running’ mode only recorded it as 1.4km. Then at the gym, I turned on ‘strength’ mode for my workout, and it told me I was at a low heart rate — despite the fact I hadn’t caught my breath after the run, and could feel my heart rate to be elevated.
The GPS issue is the most pronounced; multiple times during testing the watch wouldn’t report the full distance of a run or cycle (or, on one occasion, any distance at all, instead of the 4km I had cycled). From my testing, I seemed to lose on average 20% of the distance I actually traveled. It seems to be an issue with how the watch connects to your phone, as the Active only has Connected GPS (which utilizes your phone’s GPS, instead of having it built-in). I would have considered it being an issue with my phone, had I not tested the Band 9 Pro immediately before the Active.
The heart rate issue is also a shame — it’s one of the most important metrics that people use fitness trackers for, so the fact that it’s so obviously inaccurate is a real shame.
Now for a surprise: sleep tracking worked pretty well, surprisingly so given the rest of the performance. It was acccurate in terms of timing, even if I lay in bed reading before sleeping or remained prone for a while after waking up. It also offered basic-but-useful breakdowns of types of sleep (REM, deep, etc) as well as wake-up times and your resting heart rate (for however accurate that is…). If all you want out of a fitness tracker for is sleep tracking, this budget option might be alright.
Xiaomi Smart Band 9 Active: Features
- Mi Fitness app used on phone
- Music playback, notification handling and more
- 14-day battery life
Beyond the iffy fitness tracking options, the Xiaomi Smart Band 9 Active more or less ticks all the feature boxes you’d expect for a cheap fitness tracker.
Through Bluetooth with your phone it can tell you the weather, control your music (well, skip, back a track and play/pause) and ping you with notifications. I recommend customizing which notifications get sent to your tracker, lest you want to be pinged every few minutes with the latest weather report.
The Band 9 Active connects to your phone via Bluetooth 5.3 and the connection was faultless during my testing — except, of course, for the weird GPS issue. You connect to the Mi Fitness app, which can bring you a few extra ways to use your band.
The main one (for me) is that it gives you more depth to examine your past workouts, with a rough GPS map and other metrics. You can also see the results of various metrics tracked via the watch like training load, stress, energy and your vitality score.
You can also use the app to customize your watch to a limited degree — like I said you can set a background photo or pick from a wide range of other displays. You can also tweak some settings of the fitness tracking metrics and set a password for the tracker.
Xiaomi cites the battery life for the Band 9 Active at being 18 days, or about two-and-a-half weeks. From my testing, I’d say you can reliably get two weeks of use out of the band before needing to charge it, but that extra four days may be a stretch if you’re not sparing with your use.
