XIAOMI Smart Band 9 Pro, Sports fitness tracker, 1.74 narrow-edge quadrilateral display, 21 Days Battery Life, Upgraded sleep tracking, 150+ sports modes, 5ATM, GPS and compass, Obsidian Black

I usually do extensive research before buying a tech product. Here's my personal experience after 2 weeks of use: - 🔋Amazing Battery life (I charged once in 2 weeks) even during constant tracking of heartbeat, workouts, sleep... - 👌 Responsive touch screen - ⌚️ The head size is great for most wrists (I compared it next to a 40mm Apple Watch SE 3) -📏 The band can feel a bit too long for women's wrists (for reference, my wrist is 16cm), but there are loads of options to purchase on Amazon. - 💤 I was amazed at how it recognises my sleep and nap times so accurately!! I also loved that it suggested a sleep schedule according to my current sleep habits/animal (it was a cute addition) - 📈Tracking of heartbeat and sleep felt roughly accurate, but not too precise I would definitely recommend this smart band if you're on a budget but still want something of good quality, especially if you want to have an overall good tracking of your workouts and sleep. When it comes to a smart band, this is the best currently on the market as of Feb 2026, and would only (obviously) lose to a smart Watch like the Apple watch I compared it to. (Video compares the Xiaomi to an Apple Watch SE 3)

Have had this for about a month now. It’s a very low cost smart watch, that does everything it’s supposed to pretty well. Mostly. Set up was straightforward. It feels quite light and fragile in the hand. The battery life is superb, it needs a charge less than once a month, which is incredible. Heart rate tracking is very accurate, the best of any watch I’ve had, better than watches 10x the cost. The app isn’t good. It’s not intuitive, syncing is very bad, the watch becomes unresponsive for a while or restarts when the app is opened. It has some quirks, like telling me I’ve been standing for 14 hours when I’ve only had it on my wrist for 6 hours. But, if you want an accurate heart rate tracker that tells the time and some other stuff get this. Oh, and the date format is the wrong way round (mm/dd), which is way more annoying than it should be.

Great watch and function. Only thing it lacks is messaging capability or mic to answer phone calls. However for its price cant complain. Sleep quality feature and O2 sensor works great. Good OS. Screen size is excellent

Bought as a Which? recommended buy in May 2025 and I was sick of Fitbit's unreliability. At first it was great, although I was surprised at how few steps it registered (thought it was me being lazy buy others have also commented on low step count). Loved the long battery life but now in December 2025 it doesn't want to sync to the app and the screen can only be read in the pitch black as otherwise it is too dim and it doesn't 'wake' when you tap the screen. Such a pity because the price was very reasonable. Also customer service only Monday to Friday 9 to 6 so no good if you want support at the weekend

The watch is just OK. I got as a replacement for a fitbit and it just hasn't matched in terms of accuracy or ease of use in my opinion. It gives me some indicative indication, I can compare if I walked further one day compared to the other, but I don't necessarily trust the accuracy of the exact data in terms of step count etc. The calories was particularly frustrating, as just had some weird metric as opposed to total calories. It does have some really good features. I like the excellent battery life (lasts weeks), the low charge mode, the light feature and the customizable backgrounds. The screen is clear, and easy to read. As a watch with basic functionality it was perfectly fine, but wasn't ideal if wanting to accurately track other details.

In a couple of days, it will be a month since I bought this, EXCELLENT, when I want to count my steps when walking, you can record your jog, walk or whatever sport you are doing, I mainly use it for walking, it records your heart beat, pace, steps, so good, doesn't do blood pressure which is unfortunate. Perfect for someone who can't afford a fitbit or doesn't want to spend so much, a simple 20 quid and the battery life is excellent. It has many features such as a torch light, find my phone, measures stress and sleep patterns, i read the reviews on amazon before buying and I read the bad ones as well, I don't know what they were doing with their smart bands but it is excellent, I don't know about waterproof though, it says it is but I don't want to risk anything

I searched extensively for a Fitness Tracker to replace my FitBit when its battery died. I was looking at all the main well known brands but was hesitant to spend so much money. Eventually I opted for this watch and I have been absolutely delighted with it. The battery life is incredible, it literally lasts weeks even with daily wear and using the GPS tracker function. This used to drain my FitBit battery really fast. It tracks workouts well and the interface and operation is clear and easy. I don’t tend to use the App much. For my needs which is mainly to track dog walks and length / intensity of lifting weights at home its perfect. Really pleased for the price!

After using the Xiaomi Smart Band 9 Pro for a few weeks for workouts, sleep tracking, and daily wear—here’s what I think: it’s a strong smartband with some compromises. Great for many people, but not flawless. --- ✅ What I Loved 1. Bright, big screen that’s actually usable outdoors The 1.74-inch AMOLED with up to 1,200 nits brightness is excellent. Under sunlight I could still see notifications clearly. 2. Built-in GPS makes a big difference Finally, no phone required for outdoor runs. It supports GPS + GLONASS + Galileo + others. Nice for tracking routes more accurately. 3. Solid battery life Xiaomi claims up to 21 days in typical use, and honestly I saw close to that when I used sleep tracking, notifications, etc. If you use GPS constantly, of course it drops faster. 4. Lots of features + modes Over 150 sports/fitness modes. Good health sensors: heart rate, SpO₂, sleep (light / deep / REM), stress monitoring. 5 ATM water resistance too (so it survived splash / swim sessions for me). 5. Good build & looks The frame uses aluminum alloy, strap is decent, looks more premium than basic fitness bands. Comfortable in daily wear. --- ⚠️ What Didn’t Quite Hit 1. GPS / distance tracking isn’t perfect Some Reddit posts (and my own experience) show that while the GPS is quite good, it can be off by a small margin: distances under-reported by maybe a few percent. Not huge, but if you're tracking runs seriously, you’ll notice. 2. Sensor lag or inaccuracy under stress When things get intense (high heart rate, fast workout), the heart rate readings sometimes lag or overshoot. SpO₂ similarly can jump around depending on finger position, motion, etc. 3. UI / smoothness could be better A few users say the UI feels a bit choppy or not quite as slick as band 9 regular or other brands. Sometimes animations drop frames, possibly because the UI has more to process (bigger screen, more features). 4. Features missing / limited No built-in microphone for calls (in most markets), inability to reply to messages, etc. If you expect smartwatch-level interaction, this might feel limiting. 5. Battery drains faster with GPS / always-on display As with many bands, using those features heavily eats into battery life. If you leave GPS always on or use always-on display full time, battery-life drops.
