Xiaomi mi band 2 review

Chinese electronics giant Xiaongươi may be best known for smartphones such as the innovative Mi Mix, but it also makes a wide variety of other products, from televisions to lớn drones. Sadly, the majority aren’t sold outside Asia, and many aren’t compatible with U.S. networks or systems. One Xiaomày sản phẩm you can easily buy without such concerns is the Xiaongươi Mi Bvà 2. It’s a fitness tracker with a heart rate sensor và a super-bright OLED screen, & a sequel khổng lồ the simple, yet cheap original Mi Band. Extra features usually means an increase in price — but that’s not Xiaomi’s style at all.

There’s no shortage of fitness trackers, và although the Mi Band 2 is very affordable, has the wonderful simplicity of the original been lost — and does it still represent the value it once did?

Design và comfort

The Mi B& 2 looks very similar to the original Mi Band. There’s a central core module that pops inlớn a sllặng, silicone strap, allowing you to swap it out for straps in different colors. Once the core is in place, it’s not going anywhere at all, và is more securely fastened in than the original Mi Bvà had been (its core would sometimes pop out unexpectedly). Although soft, the silicone isn’t floppy & is secured with a pop stud & small loop. The strap is also super secure, with almost zero chance of it coming loose or falling off.

The Mi B& 2 is easy to put on with one hand, & it’s considerably more compact than most modern Fitbit trackers, such as the Fitbit Blaze. Because of this it’s suitable for all wrist sizes, & doesn’t look out of place on the thin-wristed.

Once the Mi Bvà 2 is on, it’s quickly forgotten. It’s designed lớn be worn 24 hours a day khổng lồ traông chồng activity and sleep, và it never became intrusive sầu, uncomfortable, sweaty, or annoying. It happily slips under a shirt sleeve sầu too. After wearing it on-and-off for a year, sometimes for a few weeks at a time, the silicone band still looks like new. It can really take a beating, without looking worse for wear.

Xiaongươi has engineered the Mi Band 2 with an IP67 water resistance rating, so it’ll survive a swlặng, a shower, dust, và corrosion. I wore mine in the shower, & khổng lồ wash the oto (where it spent time in & out of buckets, being lightly sponged, and under a gentle hose spray) & it still works perfectly.

Perhaps the only odd thing is it would tend to slip round my wrist — I wear it relatively loosely — so the display is facing slightly away from my gaze. This centralizes the stud fixing under my wrist, so the movement may have sầu to do with weight or the band’s center of gravity. The core module is larger than the first generation’s had been, but because it weighs only 7 grams, any additional weight isn’t noticeable.

Overall, the size makes it one of the most comfortable fitness trackers you can buy. One needs to lớn wear a fitness tracker consistently for it to be of benefit, so comfort is extremely important.

Display & heart rate monitor

The most noticeable new feature on the Mi B& 2 is the display. Although small, it’s an OLED screen that’s incredibly bright, so it’s easily viewable at both night & when exposed khổng lồ direct sunlight. It shows a variety of information, which can be customized through the supporting Mi tiện ích. Ours was set to show the time, steps taken, and heart rate measurement, but it’s easy to add calories burned, distance traveled, and battery status.


A shiny panel covers the screen; it feels like plastic, và Xiaomi promises it’s scratch resistant và won’t attract many fingerprints. Despite being exposed to lớn the elements on my wrist, it shows no sign of scuffs or marks, & it’s never a smudgy mess. During our first demo of the Mi Bvà 2, our then current Fitbit Charge’s screen cover looked considerably worse for wear after only a few more weeks of use. A year on, và the OLED screen is equally bright and attractive sầu, & has only picked up a few hairline scratches, which show in direct artificial light only.

Under the screen is a circular touchpad that cycles through the data feed. It’s not a button, and only requires a tap khổng lồ operate. Get to the heart rate screen and it’ll start taking a measurement automatically. It’s an optical monitor, much lượt thích that used on other smartphones and wearables, mounted on the underside of the core. The company recommends that you wear the Mi Band 2 tightly against the skin when taking a reading. This is a good idea. I activated it by accident quite often, & due khổng lồ it being loose on my wrist, I wasn’t getting any result. Although it can be used automatically during the night for improved sleep tracking, there’s no profile to use the heart rate sensor during a workout, except by starting it manually.

Mi app

Xiaomi’s official Mi app is compatible with Android & iOS, so regardless of the phone you use, the Mi Bvà 2 should work fine. It operated without a problem on both an iPhone 6S Plus và a Samsung Galaxy S7 Edge originally, and with an iPhone 7 Plus for our later tests. While there were connection issues during our first Reviews with the iOS app, these have sầu been cured, and it synced và updated without a problem on the iPhone 7 Plus. The app has also been regularly updated throughout the last year, mostly with bug fixes & performance improvements.

The app is quite basic. It collects data from the band & collates it in a series of graphs, one for steps and activity, the other for sleep. These are then put inkhổng lồ historical graphs covering the day, week, và month. Significant exercise periods are highlighted each day, with the time, distance, và calories burned all shown. Sleep gets a similar treatment, with the amount of time spent in bed, a deep- và light-sleep phase split, & the time you went khổng lồ sleep and woke up.



You can set a daily step count target và an igiảm giá weight you’d lượt thích to lớn achieve, và in a recent tiện ích update, lets you select one of two running profiles — indoor on a treadmill, or outdoor. This adds in continuous heart-rate monitoring during your workout, a feature missing from the earlier version of the app. Select either protệp tin, & it’ll deliver zone alerts when you reach a phối heart rate, and a pace alert for running outside. It’s also possible to use the heart rate monitor automatically during the night lớn gather more data. Both these features will obviously affect battery life. There is an alarm, but it’s not smart enough to lớn wake you during a light-sleep phase, và the band will alert you of incoming calls, system notifications, or if you’ve sầu been sitting still for too long.

Tap the “Play” button at the bottom of the screen, then the Behavior Tagging thực đơn, lớn find an extensive sầu danh sách of exercise và activity programs, ranging from ping-pong and sit-ups, lớn brushing your teeth và driving. These are trackers, monitoring movement & heart rate continuously, khổng lồ help build a picture of your day. We question their usefulness, because anything you do doesn’t show up in historical graphs, và unless it’s walking or running, doesn’t count towards your daily goals.

The phầm mềm is attractive sầu, minimalistic, and very logically laid out. It’s easy lớn use, & the pertinent information, such as step count, is immediately obvious when you launch it. However, the Mi ứng dụng is entirely devoid of advice, encouragement, or feedbachồng on your wellbeing, based on the data it collects. This is unfortunate, as it’s how value is measured in the overcrowded world of fitness trackers. After all, there’s a good chance you’re wearing one because you want to lớn get fitter, lose weight, or get better sleep. Some trackers want to help you reach your goal, và offer guidance và motivation. With the Mi Bvà 2, you’re on your own.

Accuracy và battery

After an early firmware problem that resulted in an inaccurate step count, the Mi Bvà 2 has been faultless in reliability & accuracy. Its step count is in line with competitors, with the difference between them maxing at 100 steps. The heart rate sensor had always agreed with the Apple Watch, with the pair usually coming within a couple of beats-per-minute of each other.

One of the best things about the original Mi B& was its long battery life, & although there is more giải pháp công nghệ inside the Mi Band 2, the battery is rated for trăng tròn days without a recharge. In reality, I got to đôi mươi days use with the Mi Band 2 & the battery still had 49 percent energy remaining, which is superb. The core module must be removed from the strap và fitted inkhổng lồ a proprietary charger to lớn top up the battery. It’s very reliable too. After not charging it for a month, then bringing it back inlớn service, it accepted the charge & lasted for at least another month before running out of power.

Price, warranty, & where khổng lồ buy

Xiaomày still doesn’t sell the Mi Bvà 2 through its own online store, but you can get one from Trung Quốc through an importer. We originally got ours through GearBest.com, a well-known online importer of Chinese electronics, where it’s currently priced at only $22 with free shipping. Our Model from GearBest arrived by courier a few days after ordering, và had been extremely well packaged.

Worried about what happens if the band goes wrong? GearBest provides a one-year warranty và miễn phí repair service, provided the hàng hóa hasn’t been damaged through misuse, along with a 45-day money baông chồng guarantee. Because the Mi Band 2 comes from China, there are return shipping charges lớn consider in this process, và although some are covered, situations vary, so vì bear it in mind.

Our take

The Mi Bvà 2 costs a fraction of most big-name fitness trackers, yet matches them on features & kiến thiết, making it igiảm giá khuyến mãi for the regular gym goer.

Is there a better alternative?

Because it costs less than $25, the Mi B& 2 has few challengers that can meet it head-on. The Misfit Flash costs about the same, but doesn’t have sầu a heart-rate monitor or a screen. The Moov Now costs nearly three times as much, và also can’t match the Mi Bvà 2 on features. However, the Moov Now does have a great app, with plenty of different exercise options, which is worth the extra money if you’ve sầu got it.

If you have sầu a bigger budget available, và want a more comprehensive sầu ứng dụng & fitness experience, while retaining a cool kiến thiết & beautiful screen, we love sầu the Samsung Gear Fit 2.

How long will it last?

The Mi B& 2 is water resistant, the core module stays well protected inside the silicone b&, and even after several months of wearing it, the entire product shows few signs of wear. The battery is also still going svào after this amount of time, providing around a month’s worth of use before needing a charge. If the silicone b& does break, or you fancy a color change, there are many cheap alternatives available online.

Should you buy it?

Yes. It’s light, durable, inconspicuous, easy-to-use, has a beautiful bright screen, & at less than $25 it’s astonishing value for a heart-rate monitor-equipped b&. However, we want value both in terms of price và from the feedback and guidance we get in exchange for wearing the bvà all day long. Xiaomày has updated the Mi B& 2’s ứng dụng with more workout options, making it more useful than ever; but it lacks motivational guidance, or extensive individual exercise tracking.

Whether this bothers you depends on your level of commitment lớn exercise. If you want khổng lồ know only how far you walked, how much you slept, & lớn kiểm tra your heart rate on a run, the Mi Bvà 2 is an excellent choice. However, if you’re a fitness fanatic, và want lớn trachồng specific exercises, get feedbaông chồng on your progress, and encouragement lớn keep going, then the Mi B& 2 will disappoint. This is a common problem with fitness trackers though, & not chất lượng lớn the Mi Band 2 or Xiaomi’s app.
