Update: September 21, 2020: We have updated our Xiaomi ngươi Band 4 reviews with new pricing details, software information, and more.
If you’re reading this Xiaomi mày Band 4 review, there’s a good chance you’ve either heard a lot about Xiaomi’s ngươi Band line & want to know what the hype is about, or you’ve already placed your mi Band 4 order và are awaiting its arrival.
The hype surrounding mày Band devices — & Xiaomi devices in general — is there for a reason. Xiaomi makes really good products that don’t cost a ton of money. In the age of the $1,000-plus smartphone, it’s no wonder why people are looking for low-cost alternatives lớn high-end products.
The mi Band 4 might be the product that best reflects Xiaomi’s low-cost-high-quality mantra. It starts at the low-low price of $33 in the US, or about half the price of competitors’ products. Read on lớn find out why you’d want khổng lồ choose the Xiaomi mày Band 4 over the higher-cost competition.
The Xiaomi mày Band 4 is no longer Xiaomi’s flagship fitness tracker. We recommend those in search of a low-cost fitness tracker to kiểm tra out the Xiaomi mày Band 5 or Xiaomi mi Band 6.
Xiaomi mi Band 4 review notes: I’ve been using the Xiaomi ngươi Band 4 as my main fitness tracker for roughly six days, running firmware version 1.0.5.39. The Xiaomi mi Band 4 review unit has been connected to my Google px 3 running game android 9 Pie for the duration of this review.
Xiaomi mày Band 4 review: The big picture
The Xiaomi ngươi Band 3 was one of the best value fitness trackers of 2018, & the mi Band 4 aims to lớn improve on it in a few key ways. It has a better display & more activity profiles, but with those things comes a slight price bump, though the ngươi Band 4 is still significantly cheaper than other fitness trackers with similar feature sets.
The question is, are you really getting anything worthwhile by spending an extra $50 on a competing product, or should everyone run out & buy the mày Band 4 right now? That’s what we’ll answer in our Xiaomi mày Band 4 review.
Let’s be honest: None of Xiaomi’s ngươi Band devices have ever been the most well-designed pieces of tech, but the ngươi Band 4 is an improvement. It’s still one of the more generic-looking fitness trackers out there with its simple black band & unassuming case, but the improved display saves the ngươi Band 4’s design in my opinion.
It’s a 0.95-inch RGB AMOLED display this time around — a big step up from the ngươi Band 3’s smaller black-and-white display. The 120 by 240 px density is sharp và the 400-nit brightness means it’s easy to lớn see in direct sunlight. It’s a touchscreen display, so you’ll do most of your on-device navigation through taps và swipes. Swipe up or down to lớn select different modes or settings, swipe left or right from the watch face lớn access music controls, or swipe right to go back from a different screen. You can also tap the capacitive button underneath the display to go back. Easy.

The Xiaomi ngươi Band 4 received a software update in October 2019 that added the ability to set a custom screen timeout between 5 và 10 seconds. With that 1.0.7.04 update, mi also brought new watch faces and improved swim tracking lớn the mi Band 4. A mid-January 2020 update khổng lồ version 1.0.9.22 brought bug fixes khổng lồ the mày Band 4. We couldn’t find an official changelog for the update, though a Reddit thread said notification text is smaller after the update.
The fitness tracker case easily detaches from the silicone band if you’d like to swap it out for another band. Và don’t worry, there are already plenty of third-party mi Band 4 bands available on Amazon. The mi Band 4 case is compatible with mày Band 3 bands, too.

The band that ships with the ngươi Band 4 is made of silicone & feels comfortable. It’s not the highest quality rubber you’ll find on a fitness tracker — it’s a little too rigid for my taste — but it gets the job done.
The optical heart rate sensor ever-so-slightly protrudes from the bottom of the case, but not enough to lớn leave a mark on your wrist after wearing it for a few hours.
Throughout my testing, I didn’t notice any connectivity issues between the mi Band 4 and my pixel 3. Perhaps that’s due to the ngươi Band 4’s updated công nghệ bluetooth 5.0 tư vấn compared to the previous generation’s công nghệ bluetooth 4.2 support.
Below the heart rate sensor sit two little pins for charging. When it’s time khổng lồ charge, simply slide the ngươi Band 4 case into the included charging cradle and it should be topped up in about 45 minutes. A quick note on the charging cable: I hate it. It’s about four inches long, so it’s going lớn dangle from any USB charging port not sitting directly on a desk.
The good news is you won’t have khổng lồ charge the mày Band 4 very often at all. With normal use, xiaomi mi says the 135mAh battery will last about 20 days on a single charge. I haven’t been using mine for trăng tròn days, but I can tell you the battery is pretty great so far. I’m currently sitting at a 70% charge after a full charge last Friday, và that’s after three long runs và the heart rate sensor being on in 10-minute intervals.
The mày Band 4 will keep track of all the basics: steps taken, distance traveled, calories burned, resting & active heart rates, & sleep. It doesn’t have a built-in GPS, so your distance metrics won’t be very accurate if you’re going out for a run with only your fitness tracker. However, it comes with a connected GPS feature, so you can track your workouts with GPS if you don’t mind bringing your phone.
Notably, the Samsung Galaxy Fit doesn’t feature connected GPS, though the Fitbit Inspire and Inspire HR both do.
On April 1, 2020, xiaomi rolled out software version 1.0.9.42 lớn the mi Band 4, which brought a fix for inaccurate step tracking. This update also brought the ability to lớn unlock your Windows 10 máy tính xách tay when your ngươi Band 4 is nearby.
Another area where the ngươi Band 4 stands out is the number of workout modes. It can track the following exercises: treadmill, outdoor running, cycling, walking, pool swimming, & the generic “exercise” workout. That may not seem like much, but its predecessor isn’t able to lớn track pool swimming or generic exercises at launch. The mày Band 3 can now track exercises, but still isn’t able lớn track swimming exercises.
Speaking of pool swimming, the mi Band 4 can recognize five different swimming styles & record 12 different data sets, like swimming pace & stroke count. It also carries a water resistance rating of 5ATM.
I wouldn’t normally mention that you can start an activity from the mi Band 4 itself (instead of pressing “start” from the app), but you can! At launch, the mày Band 3 wasn’t able khổng lồ start exercises from the band itself, but it gained this functionality at a later date.
I took the ngươi Band 4 on multiple outdoor runs và compared it with my Garmin Forerunner 245 Music & Wahoo Tickr X heart rate strap. Though it doesn’t have as many sensors as the Forerunner, the ngươi Band 4 was actually quite accurate. Step counting và calories burned metrics from the mày Band 4 were very close lớn the Forerunner 245 Music’s metrics. The only major outliers during my testing were distance và pace metrics, but that’s because the ngươi Band 4 doesn’t have GPS & I didn’t thử nghiệm the connected GPS feature during those runs.

Heart rate recordings — both resting & active — with the mi Band 4 are decent. I’ve attached a few comparison screenshots on a run I took with the Forerunner 245 Music & Wahoo Tickr X.
It’s a bit hard khổng lồ tell from the screenshots (the ngươi Fit phầm mềm doesn’t display heart rate recordings very well) so I’ll walk you through it.Max heart rate:Wahoo Tickr X (control): 170bpmXiaomi ngươi Band 4: 173bpmGarmin Forerunner 245 Music: 176bpmAverage heart rate:Wahoo Tickr X (control): 142bpmXiaomi mi Band 4: 155bpmGarmin Forerunner 245 Music: 145bpm
The Forerunner và Mi Band 4 stayed quite close lớn the Tickr X chest strap throughout the workout. All three devices had a similar max heart rate, though the ngươi Band 4 was on the high side in terms of averages. The mi Band 4 actually did a better job of catching the slight dip at the ~10-minute mark, though it didn’t go nearly as low as it needed to: The Tickr X got all the way down to lớn ~55bpm while the mi Band only dipped down to ~150bpm.

Both the Forerunner and Mi Band also caught the dip at the ~16-minute mark, but the mày Band 4 clearly glitched at that point. It flatlined for a few minutes, jumped back up at ~18 minutes, only to lớn flatline again until ~21 minutes.
We see these things happen with wrist-based heart rate sensors quite often, so it’s not surprising to see it happen lớn the ngươi Band 4. Overall, it will give you a good idea as lớn where your heart rate generally is, but don’t rely on it fully for higher-intensity workouts.
With software version 1.0.9.48, xiaomi brought a new heart rate sharing feature, allowing the mày Band 4 lớn communicate heart rate data with other fitness apps.
Sleep tracking is another one of the mi Band 4’s strongest areas. It’ll track your deep/light sleep & time awake, và it’ll give you a sleep score from 1-100 by comparing your data to lớn other mi Fit users’ data.
Throughout my time with the device, I haven’t noticed any major issues with sleep tracking — the ngươi Band 4 always seems khổng lồ report my time asleep & time awake pretty accurately.

For a device this small & cheap, mi was able to lớn pack quite a lot of smart features into the mày Band 4.
Before we get too far into it, I’m using the mày Band 4 meant for regions outside of China, so my reviews unit does not support contactless payments with Alipay, nor public transportation payments. It also lacks Xiaomi’s Xiao AI assistant. For more information on the Chinese model, head here.

The mày Band 4 can relay call, text, email, và just about any other notification you receive on your smartphone. Notifications come through lớn the mi Band 4 right away. You can’t reply to lớn any of them, and due to the little display some messages can be hard to read, but it’s still a nice feature to have.
I’m surprised at how many customization options xiaomi included in the mày Fit app. You can’t find some of these little conveniences in every fitness tracker:Vibration pattern: Each notification type can be programmed with a custom vibration pattern so you can tell the difference without even looking at the screen.Schedule for auto screen wake up: You can phối the mi Band 4’s display khổng lồ activate when you lift your wrist at certain hours of the day. That means the device won’t burn your eyes by accident when you’re trying khổng lồ fall asleep.Night mode: After sunset (or at your preferred time), your mày Band 4’s screen brightness will be lowered.Do not disturb: Many fitness trackers have built-in DND modes, but the mi Band 4’s can be turned on even without your phone nearby. If you’re getting bombarded with notifications và need them to stop, switching to DND mode can be done in only a few taps.
The mi Band 4 also supports different watch faces. There are a fair amount of watch face options available in the ngươi Fit app. Roughly half of them are colorful digital faces, while the other half feature cute, big-eyed cartoon animals. To lớn each their own.
There are also built-in vibration alarms, a “find my mày Band” feature if you misplace it, on-device weather, & the ability lớn control your smartphones music from your wrist. I’ve found music controls lớn be particularly handy when walking around the house và listening to podcasts.
In August 2020, mi released version 4.4.0 of its ngươi Fit app, which brought the battery percentage to lớn the mi Band 4’s display.
Xiaomi’s mi Fit ứng dụng is what you’ll use khổng lồ pair the ngươi Band 4 khổng lồ your phone & view all your activity stats, unlike the Galaxy Fit which uses multiple apps for device settings and health tracking.
There are three sections of the ngươi Fit phầm mềm — workout, friends, and profile — which are all pretty straightforward. Friends is where you can connect with other mày Fit users lớn see their activity và health info, và the profile section contains all your personal info, goals, và settings.
The workout section contains four sub-sections: status, walking, running, và swimming. Walking, running, and swimming are only used for manually starting those types of activities from your phone. The status section is where you’ll find the current day’s activities và goals.
I don’t like how difficult it is to check into your workout or activity history. There’s no button for it, so you may find yourself tapping around until you stumble across it. You can access your history by tapping the activity card in the status tab, swiping over lớn my workouts, tappingsteps today, thenhistory on the bottom of the screen. As someone who constantly checks into workout progression over time, this is a little cumbersome.
Once you’re there, the mày Fit app will display tons of information, even down to the small five-minute activities it records throughout the day.
If you’re a diehard Google Fit user & can’t give up the ứng dụng for anything, good news: You can sync your ngươi Fit data with Google Fit. Once you connect your accounts in the ngươi Fit settings menu, all activities recorded by the mày Band 4 will be sent over khổng lồ Google Fit. Personally, I haven’t experienced any of the recent Google Fit issues others have, so just know that your experience with syncing mi Band 4 data to Google Fit might vary.

For the most part, the ngươi Fit ứng dụng is a well-rounded, easy-to-use fitness platform (aside from the ease of checking workout history). The ứng dụng could benefit from even more social features and compatibility with other fitness applications, and I did notice a few bugs in the ứng dụng throughout my time using it. Overall though, it’s perfectly serviceable in its current form.
Value for the money và the competition
Here’s where the Xiaomi ngươi Band 4 really shines. It’s available in the US for just $38, less than half the price of the Fitbit Inspire HR và Samsung Galaxy Fit, which are the mày Band 4’s main competitors.
Even though the ngươi Band 4 was a good buy when it launched, the new hotness is the Xiaomi mày Band 5. It’s an all-around better fitness tracker, though it is slightly more expensive at just over $40 in the US.
Realme also released a mày Band 4 competitor called the Realme Band, but it really doesn’t hold a candle to lớn the mày Band 4. Xiaomi mi is also planning on releasing the Xiaomi ngươi Band 4C sometime soon, though it will likely be a rebranded Realme Band. Again, you should just buy a Xiaomi mi Band 4.
Xiaomi also launched the ngươi Band 4 in India on September 17, 2019, & it’s available via Mi.com & Amazon India. The fitness tracker’s Indian price is set at 2,299 rupees (~$32), making it slightly cheaper than the UK và US pricing.
The ngươi Band 3 was an excellent fitness tracker, and that doesn"t change with the Xiaomi mày Band 4. It monitors your heart rate, sleep patterns, & more.
