Xiaomi Smart Band 9 Pro review: One big upgrade that comes at a price

Xiaomi Smart Band 9 Pro: One-minute review

Chinese tech company Xiaomi is almost single-handedly keeping the cheap fitness tracker market alive, and the new Xiaomi Smart Band 9 Pro is its new entry for people who want to monitor their health on the cheap, but want a nice big screen at the same time.

This health gadget is a follow-up to the Xiaomi Smart Band 9, released in mid-2024, and for all intents and purposes, it’s a very similar fitness tracker – too similar, for reasons we’ll get to. It has the same software, is largely as accurate for measuring your health, and connects to your phone in the exact same way.

Its key selling point is that, unlike its non-Pro predecessor, the Xiaomi Smart Band 9 has a big display. This won me over more than I thought it would – it doesn’t feel much more of a burden on the wrist yet is much easier to press while you’re sprinting down a park path or balancing on a parked bike. I also see it being much more convenient from an accessibility viewpoint, so if fiddly fitness tracker screens put you off, this is the Smart Band to buy.

However with great screens come great price tags and the Smart Band 9 Pro pushes the price up a lot more than its older sibling – it’s not reaching the price point of Garmin’s cheapest options or second-hand Fitbits, but if you’re on the market for something really affordable, its price might give you reason to pause.

Size and cost upgrades aside, the Xiaomi Smart Band 9 Pro ostensibly has some improvements to sleep, blood oxygen, and heart rate monitoring – it didn’t feel that different to me. But I was disappointed in how lots of my issues with the previous band weren’t fixed, namely regarding buggy software.

My experience of using the Smart Band 9 Pro was punctuated by notifications waking me up in the early hours, alerts being hidden by other alerts, and the watch maintaining a very lackadaisical approach in waking when I raised it up. These are all issues I reported in my review of the first band, and they’re back here.

As a tech fan, I wasn’t impressed by how similar the Smart Band 9 Pro is to the Band 9, but the perk of its limited number of upgrades is that it functions just as well as that stellar fitness tracker did. Its activity tracking modes aren’t in-depth but they are handy for workout fans and I found the watch very accurate and useful for tracking distance and heart rate on runs.

When it’s working bug-free, the Band 9 Pro is also a useful lifestyle companion with music control, timers, and notification handling, all features that came in handy during testing.

So the Xiaomi Smart Band 9 Pro is definitely an upgrade over the Band 9 you should consider if the price doesn’t put you off, but you really should ask yourself if you need the bigger display.

Xiaomi Smart Band 9 Pro: Specifications

Xiaomi Smart Band 9 Pro: Price and availability

• Unveiled in October 2024
• Goes for £62.99 / AU$99.99 (roughly $75)
• Matches Smart Band 8 Pro

Xiaomi announced the Smart Band 9 Pro as well as the Active model in late October 2024, initially for its Chinese market, but it slowly released it globally in the following months.

You can pick up the Xiaomi Smart Band 9 Pro for £62.99 / AU$99.99 (roughly $75). That’s a fairly significant price hike, in the UK at least, over the $60 / £24.99 / AU$79.99 ‘standard’ Band 9, though it matches its predecessor the Smart Band 8 Pro.

The price cements the Band 9 Pro as the premium member of its tripartite, with the Band 9 Active coming in at £19.99 / AU$44.99 (roughly $25). The price puts the tracker equal to, or above, some of the best cheap fitness trackers in terms of cost, and I don’t quite feel that the feature set has seen an increase in step with the price hike.

In a few regions, Xiaomi sells extra straps for the Band 9 Pro, and it sent TechRadar one of these alongside the fitness track for testing. However, at the time of writing, these aren’t for sale in the UK.

Xiaomi Smart Band 9 Pro: Design

• Bigger body than rivals, but not much
• Large 1.74-inch AMOLED screen
• Screen space is really useful

Its suffix is ‘Pro’ but that could well be ‘Gro’ because the Xiaomi Smart Band 9 Pro is, in effect, a bigger version of the non-Pro model in terms of design. That is to say, it’s a standard fitness tracker that’s been scaled up a notch.

The band that comes in the box is made of TPU, and I found it pretty fiddly to clasp but comfortable when worn. It supports a pretty large variance in wrist size, which isn’t something you can say about all fitness trackers. It has an easy-release mechanism so to remove or replace the bands, you simply press a small button on the Smart Band’s body, and I found this easy to do.

You can pick up the band in three color options: black, silver (with a white strap), and rose gold (with a pink strap). As you can see in the images, I used the latter.

The body itself measures 43.3 x 32.5 x 10.8mm, not including the band, and weighs 24.5g. That makes it a little chunkier and portlier than many svelte fitness trackers on the market but its weight wasn’t noticeable on the wrist. In fact, I found it just as comfortable as any other tracker I’ve used.

Next, we come to the screen, the biggest change over the ‘standard’ Band 9 (literally). It measures 1.74 inches diagonally, and like the body, it’s wider and shorter than its sibling. Its resolution is 336 x 480 and the max brightness is 1200 nits, though unlike on the Band 9 I found the automatic brightness wasn’t always that quick. I sometimes struggled to see what I was looking at on my band when outdoors until it had taken a few seconds to adjust the brightness.

This extra screen space will be fantastic for people who don’t get on with the teenie icons of most fitness trackers and smartwatches, and it was especially useful when running so I could easily press a button without needing too much precision.

In terms of protection, the Xiaomi Smart Band 9 Pro has 5ATM water resistance: it can survive at depths of up to 50 meters for 10 minutes. Xiaomi advises you not to take it in heated water, though, like a sauna or in the shower.

Xiaomi Smart Band 9 Pro: Performance

• Uses phone’s GPS but has heart rate and other trackers
• Over 150 fitness tracking modes
• 21-day battery life

In the ‘specs’ section above, I quoted Xiaomi’s estimate for the Smart Band 9 Pro’s battery life of 21 days. However in my testing, I found that the band far exceeded this – it lost a third of its charge in eight days, which included multiple runs (including a three-hour one), several weights training sessions, and sleep tracking on most of the nights. That would put the battery life at closer to 24 days although your mileage will vary.

A 14-day battery life is pretty standard for fitness trackers but 24 days is stellar, so I don’t imagine that the band will let you down. Charging is done with a proprietary charger that plugs into any USB port.

The range of workouts is the same as on the standard band, so there are over 150 fitness tracking modes. Most of these are pretty barebones: they monitor time, your heart rate, and a rough count of the calories burned, so whichever of them you select from the watch largely just dictates how it shows up in your app workout log.

A few of them have more information though, with some like running and cycling using GPS. This isn’t standard GPS but connected GPS, which means the band uses the GPS from your paired smartphone – you can’t go on workouts without your mobile by your side.

This is therefore as accurate as your smartphone, but that’s nothing to turn your nose up at – I ran a distance that was measured to be 5K, and the watch told me I ran 5.05km, which is a 1% error margin.

Sleep tracking is present, and it’s not as in-depth as on a fancy smartwatch: you find out how long you slept, how it’s broken down into deep and light sleep and wake-ups, and what your average heart rate was. According to Xiaomi, the sleep tracking has seen an upgrade in the Band 9 Pro.

Other metrics that are tracked – to dubious levels of reliability – are your stress, energy level, and ‘vitality score’ or cumulative exercise over the last week. The watch also tracks blood rate oxygen and heart rate and these are, according to Xiaomi, also improved over the original band.

Xiaomi Smart Band 9 Pro: Features

• Mi Fitness app used on phone
• Music playback, notification handling and more
• Some bugs with app and watch

I found the Xiaomi Smart Band 9 Pro quite buggy, which isn’t something that I’m too surprised about given other fitness trackers from the maker that I’ve tested, but it was more pronounced here as some examples disrupted my experience.

Both my most prominent examples come from the band’s otherwise effective notification handling. Sometimes notifications would appear at the same time as, and therefore override more important information; the Pro was very confused when an interval pop-up was immediately succeeded by a message notification, meaning I couldn’t see how many kilometers I’d just hit. And the more annoying one is that, even with do not disturb enabled, notifications would buzz on my wrist in the middle of the night – I was woken multiple times, once at 1 am, by notifications appearing on my wrist.

This latter one is something I experienced with the Band 9, as is another lesser issue: raise-to-wake is unreliable, and sometimes you can lift up your wrist and be met by a black screen.

I shouldn’t compare those two fitness trackers too much, though, because the overall experience of using the Band 9 Pro is great thanks to the larger display. A lot more information can be shown at once using its various widgets: you can see the weather for the next few days, your heart rate on a graph, and a music player to let you pause or skip songs. Buttons overall are naturally a lot bigger, which is a great accessibility win.

Well, most buttons are great, but the exception is in the app drawer which you open by swiping up from the bottom. This is a grid of 26 buttons for different features, and none of them are labeled, so you have to guess which does what. Many of them are identical: two are icons of running people, in different colors, and it’s a real trial-and-error experience. Luckily most of the features that I found myself using can be accessed in other ways, namely by swiping through the home page widgets.

More features come from the tie-in Mi Fitness app, which you download on your phone. It lets you see your fitness and health details in much more detail as well as change your watch face from a huge range of options (including custom photos), see historical data, and set up various features.
