Full Review Xiaomi Mi Band 2

The Xiaomi Mi Band 2 is a part of the custom of the Chinese firm, recognized for its tremendous low cost units.

As for the previous versions of the gadget, we are in the presence of a smartband for primary exercise monitoring, outfitted with an accelerometer and capable of rely steps, calories burned and distances traveled.

The Xiaomi Mi Band 2 additionally screens sleep and by way of the Mi Match app for smartphones supplies a practical summary analysis of the wearer's fitness degree, recognizing even between several types of activities reminiscent of operating or coaching in the fitness center.

Notably related are the hardware innovations launched in this mannequin, made even more engaging by the mixing of an HR sensor for monitoring coronary heart fee and a OLED clock display, for knowledge consultation immediately on the system and reception – by way of Bluetooth connection – notifications by telephone.

The Xiaomi Mi Band 2 is product of waterproof supplies, outfitted with a long-lasting battery and snug and mild sufficient to be worn without issues in everyday life, like several self-respecting activity tracker.

Design and Materials

Xiaomi Mi Band 2 PackThe Xiaomi Mi Band 2 instantly seems for what it is: a reasonable and mass produced smartband. The design is nice however toyastic, each for the brilliant colours by which the alternative straps can be found, and for the consistency of the supplies.

The complete gadget is product of aluminum and plastic (the central Mi Core module) and thermoplastic elastomer for the wrist band. The primary physique measures 40.three x 15.7 x 10.5 mm, while the adjustable strap has an general length of 235 mm. Module and strap have a very low weight: together they don’t exceed 18 grams.

As typical, the guts of the system could be easily removed and inserted into bands that may be purchased individually. The essential mannequin is in black, however Xiaomi has additionally made it in blue, green and orange, to which is added an already long record of variants proposed by third events, as is generally the case for smartphone instances.

The IP67 certification allows brief exposures to recent water and use within the shower and the hypoallergenic strap is manufactured from anti-sweating material.

Not as resistant is the half-inch OLED display. On paper it must be anti-scratch and finger-proof, however in actuality it has proved – quite the opposite – too straightforward to scratch. Those that love that their gadgets all the time seem to return out of the manufacturing unit will do properly to spend money on a package of protective movies.

The display can also be not very clear but at the peak of the handful of knowledge that we’ll find to seek the advice of on it, specifically time, calories, coronary heart fee and steps. For measuring distances and other extra advanced info, we should depend on the smartphone and configurations by way of the app.

The show has no contact interface and is managed by a single “button”, a small disc-shaped surface beneath it. The accelerometer permits a minimal recognition of the consumer's movement. Approaching the wrist, the system will reactivate the show considering that you simply need to consult it to see the time or access the opposite screens.

The central module additionally houses the rechargeable 70 mAh lithium battery and the HR optical sensor, constructed into the again of the case, in touch with the wrist.

Features and Functionality

Xiaomi Mi Band 2 UseThe options of the Xiaomi Mi Band 2 are summarized in its three primary screens: one for the hour, one for the steps and the final for the guts fee, with the option of including more for the battery indicator and the distances .

The cardio sensor is likely one of the most interesting elements for this system and Xiaomi claims to have perfected both the reliability of the hardware, superior to those put in within the Mi Band Pulse, and that of the Mi Fit app, suitable with Android ( from 4.four upwards) and iOS (from 7.0).

The subject of the revision was additionally the algorithm for measuring the steps, coupled to the accelerometer and optimized for an correct calculation of the displacements, but with an clever use of the sensor, to save lots of battery.

The opposite new function for the Mi Band line is the OLED display, also designed to subject the lithium provide to as little stress as attainable. Though it isn’t a touchscreen, the interface could be very clear and easily accessible, because of the touch-sensitive flat button used to navigate the screens.

The Mi Match app, as we stated, was up to date for the event and now collects knowledge in a extra organized means, summarizing steps, calories, distances traveled, physique temperature, weight and sleep phases. The Xiaomi Miband 2 is in reality outfitted with automated monitoring of sleep and vibration, usable each as an alarm clock and as a silent alert for notifications from smartphones, proven synthetically on the display and out there in full solely on the telephone.

The functionalities accessible by way of the app do not end right here and present for the evaluation of parameters on a every day, weekly and month-to-month foundation, which may be shared with other Xiaomi users on social networks.

Even when we determine not to publish our private progress, the app will tell us anyway, with a proportion value, where we rank relative to the every day common of others. For example we’ll know that the entire of our steps is greater than that of 70% of the “competition”, or that our hours of sleep exceed these of 40% of other smartband house owners and so on.

The private objectives that may be set in-app (for now solely associated to the pedometer) and the inactivity alerts contribute to motivational incentives. At common intervals the Xiaomi Mi Band 2 will remind us to dedicate a quick period, from the adjustable period all the time with app, to bodily exercise, to maintain us in shape.

The conduct of the battery will clearly rely upon the use we make of the gadget. The manufacturer guarantees at the least 20 days filled with autonomy, but the knowledge just isn’t confirmed both by our exams or by those made by different reviewers. A more sensible estimate comes close to 12 days, with lively cardio sensor, receiving notifications and frequent vibrations.

A end result decrease than that of the previous Mi Band, which nevertheless had no display.

Exercise Monitoring features

Xiaomi Mi Band 2 SmartphoneThe Mi Fit app has been enriched with more complete menus for the analysis of the info offered by Xiaomi Mi Band 2. Ideally, the “Statistics” merchandise should embrace the activities performed (distinguishing between operating and common coaching), displaying a historical past of the creating our fitness degree and helping us plan the subsequent transfer.

Actually, the Xiaomi app is just not yet at the peak of other devoted platforms and also exhibits limitations in every day activity monitoring.

A facet nonetheless to be refined is that of automated recognition of actions. In some instances, the sensor struggles to differentiate between operating and coaching and typically interprets the actions of the wrist as an indicator of bodily motion even when we have now not moved.

Energy are monitored, however not at the ranges of other comparable units per band, akin to Fitbit Alta, which also takes under consideration calories burned outdoors the precise bodily exercise periods.

We fly over the shortage of a GPS, which would have made the worth rise by canceling the raison d'être of Xiaomi Mi Band 2 as a low-cost smartband, while we don't apologize for the doubtful implementation of the cardio sensor.

The guts price shouldn’t be monitored 24/7, but solely occurs particularly conditions and when specifically requested with a faucet of the disk underneath the show, preventing customers more taken with sports activities efficiency from designating cardio zones and respecting them during coaching.

Every part is compounded by the absence – in the app – of a context during which to insert cardio knowledge, introduced as a easy listing of readings, with synthetic labels (sluggish, normal or quick beat) and some recommendation on the best way to “train” the our coronary heart price.

Attention then to the positioning of the smartband on the wrist, as a result of the optical sensor, to perform correctly, have to be very nicely adherent and shielded from potential exterior mild infiltrations.

Respecting these circumstances, HR monitoring works quite nicely (especially on brief journeys) and even the estimate of distances extrapolated from the steps is close to that of less economic units.

Sleep Monitoring

The Xiaomi Mi Band 2 mechanically screens sleep. The accelerometer recognizes the start and finish of night time sleep by itself and retains the resting coronary heart price underneath management every ten minutes, offered that this accent function has been activated within the Mi Fit app.

All the time to the app we should make reference for the session of the outcomes, obtainable starting from the next morning. We’ll know not only how a lot we slept, but in addition what number of hours have been marked by a deep and restorative sleep and what number of have registered a lighter rest.

Mi Match permits the activation of multiple alarms by way of vibration and recapitulates the info in special graphs, to allow anyone to catch their sleep habits on the fly and modify them to adopt a healthier way of life.


The unprecedented integration of an OLED show lastly permits the Xiaomi Band 2 to transcend the temporary LED alerts of the earlier smartbands, however we’re nonetheless far from a complicated help for sensible notification.

The arrival of telephone calls, SMS e-mails and push updates is accompanied by a vibration alert and by the appearance on the display of an icon (totally different for each sort of notification), while the smartphone stays indispensable both for consultation and for the sending a potential reply.

Our Opinions

The standard of a product is usually inversely proportional to its worth and this small golden rule couldn’t be truer for the Xiaomi Mi Band 2, so the manufacturer has set a launch worth of solely € 20.

The gadget has lately arrived available on the market and the distribution outdoors China has been lower than the demand, a lot in order that the worth of the gadget can levitate as much as 50 € on the circuits for the extra mainstream online purchasing, like Amazon.

Figuring out the place to look, you’ll find it in a more acceptable range between 25 and 35 €, while for the more affected person we feel that in the summer period, Xiaomi will double the manufacturing to “flood” the European market beginning next October, in the hope of repeat the success of the first Mi Band, bought in hundreds of thousands and tens of millions of copies.
