Xiaomi mi band 2 review

  -  

Chinese electronics giant mi may be best known for smartphones such as the innovative mày Mix, but it also makes a wide variety of other products, from televisions lớn drones. Sadly, the majority aren’t sold outside Asia, and many aren’t compatible with U.S. Networks or systems. One Xiaomi sản phẩm you can easily buy without such concerns is the Xiaomi mi Band 2. It’s a fitness tracker with a heart rate sensor and a super-bright OLED screen, and a sequel to lớn the simple, yet cheap original ngươi 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 mày Band 2 is very affordable, has the wonderful simplicity of the original been lost — và does it still represent the value it once did?

Design & comfort

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

The ngươi Band 2 is easy to lớn put on with one hand, và 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, và doesn’t look out of place on the thin-wristed.

Once the ngươi Band 2 is on, it’s quickly forgotten. It’s designed lớn be worn 24 hours a day khổng lồ track activity and sleep, and it never became intrusive, uncomfortable, sweaty, or annoying. It happily slips under a shirt sleeve 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.

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

Perhaps the only odd thing is it would tend to lớn 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 to vày with weight or the band’s center of gravity. The chip 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 form size makes it one of the most comfortable fitness trackers you can buy. One needs lớn wear a fitness tracker consistently for it khổng lồ be of benefit, so comfort is extremely important.

Display and heart rate monitor

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


A shiny panel covers the screen; it feels lượt thích plastic, và Xiaomi promises it’s scratch resistant và won’t attract many fingerprints. Despite being exposed khổng lồ the elements on my wrist, it shows no sign of scuffs or marks, & it’s never a smudgy mess. During our first thử nghiệm of the mi Band 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, & the OLED screen is equally bright & attractive, and 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, & only requires a tap to operate. Get to the heart rate screen & 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, và 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 Band 2 should work fine. It operated without a problem on both an iPhone 6S Plus & a Samsung Galaxy S7 Edge originally, và with an iPhone 7 Plus for our later tests. While there were connection issues during our first đánh giá with the ios app, these have been cured, và it synced & updated without a problem on the iPhone 7 Plus. The ứng dụng has also been regularly updated throughout the last year, mostly with bug fixes and performance improvements.

The tiện ích is quite basic. It collects data from the band and collates it in a series of graphs, one for steps & activity, the other for sleep. These are then put into historical graphs covering the day, week, and 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- & light-sleep phase split, và the time you went lớn sleep and woke up.

You can set a daily step count target và an ideal weight you’d like to achieve, và in a recent phầm mềm 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 profile, và it’ll deliver zone alerts when you reach a phối heart rate, & a pace alert for running outside. It’s also possible to lớn use the heart rate monitor automatically during the night to 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, & the band will alert you of incoming calls, system notifications, or if you’ve been sitting still for too long.

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

The ứng dụng is attractive, minimalistic, and very logically laid out. It’s easy to use, & the pertinent information, such as step count, is immediately obvious when you launch it. However, the Mi phầm mềm is entirely devoid of advice, encouragement, or feedback 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 get fitter, thua thảm weight, or get better sleep. Some trackers want khổng lồ help you reach your goal, và offer guidance và motivation. With the mi Band 2, you’re on your own.

Accuracy và battery

After an early firmware problem that resulted in an inaccurate step count, the mày Band 2 has been faultless in reliability and 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 táo khuyết Watch, with the pair usually coming within a couple of beats-per-minute of each other.

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

Price, warranty, và where lớn buy

Xiaomi still doesn’t sell the mi Band 2 through its own online store, but you can get one from china 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 mã sản phẩm 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 and không lấy phí repair service, provided the product hasn’t been damaged through misuse, along with a 45-day money back guarantee. Because the ngươi Band 2 comes from China, there are return shipping charges lớn consider in this process, and although some are covered, situations vary, so vì bear it in mind.

Our take

The ngươi Band 2 costs a fraction of most big-name fitness trackers, yet matches them on features and design, making it ideal for the regular gym goer.

Is there a better alternative?

Because it costs less than $25, the mày Band 2 has few challengers that can meet it head-on. The Misfit Flash costs about the same, but doesn’t have a heart-rate monitor or a screen. The Moov Now costs nearly three times as much, & also can’t match the mi Band 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 got it.

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

How long will it last?

The mày Band 2 is water resistant, the chip core module stays well protected inside the silicone band, và even after several months of wearing it, the entire sản phẩm shows few signs of wear. The battery is also still going strong after this amount of time, providing around a month’s worth of use before needing a charge. If the silicone band does break, or you fancy a màu sắc 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, và at less than $25 it’s astonishing value for a heart-rate monitor-equipped band. However, we want value both in terms of price và from the feedback and guidance we get in exchange for wearing the band all day long. Xiaomi has updated the ngươi Band 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 màn chơi of commitment lớn exercise. If you want to lớn know only how far you walked, how much you slept, và to check your heart rate on a run, the mày Band 2 is an excellent choice. However, if you’re a fitness fanatic, & want lớn track specific exercises, get feedback on your progress, & encouragement to lớn keep going, then the mi Band 2 will disappoint. This is a common problem with fitness trackers though, và not unique to the ngươi Band 2 or Xiaomi’s app.
