Xiaomi Mi band 4 review:Everything has changed except the wristband

The rubber wristband is keep same with Mi Band 3

The Xiaomi Mi band 4 is still the design of the core set in the wristband. Most of the smartwatchs, such as Sony, were also designed this way. For sports-based products such as "hands", the replaceable rubber wristband seems to be the best solution at present. After all, the rubber itself may age and change color, and the user can often change frequently.

The Xiaomi smartwatch is the same as the 4th and 3rd generation wristbands and can be used universally. But the 4th generation still needs to be taken down and charged, but the charging port is placed at the bottom.

​

The core of Mi band 4 is thicker than the previous generation, but it is still 5ATM, which is the ability to waterproof 50 meters. Let Xiaomi smartwatch finally enter the color screen era, although the screen is only 0.95 inches because of the volume limit, but the resolution is 240x120 pixels, the pixel density is calculated to be around 280, the pixel can be seen, but it will not feel very grainy.

Color AMOLED screen makes Mi band 4 unique

Because of the color screen, the corresponding UI is more beautiful, the dial is more, and the display mode is much more intuitive. The most ideal result is probably the theme dial demonstrated at the conference. Of course, at present, our evaluation prototype uses the beta version of the app, and this part of the function is not yet online.

This last point is most evident when a WeChat notification is sent. Also because of the color screen, the new mobile payment function has been added. Although the implementation method is only an Alipay QR code prepayment, it needs to be saved first and then spend money, but after all, it has a big step better than the black and white screen product. You have to buy a bottle of water in the middle of the road and you can raise your hand.

Xiao Ai is a "text version"

The front structure of the Mi band 4 is still the layout of the buttons on the upper screen. However, as the product finds that the button is from the original metal solid key to the three-generation groove touch, the screen is now larger and the touch is more sensitive. However, although the control method is still "touch screen + button below", the latter function is weaker than the black and white screen.

Mi band 4 built a Xiaoai classmate, so it is called "AI smart smartwatch", but this function is not the same as imagined. Because there is no speaker, it is not the experience of the speaker; although there is a microphone, but can not directly wake up to the smartwatch, but slide the screen to the left of the dial interface, small love appears, speak to it, the corresponding text is given on the screen answer.

NFC function equipped

NFC function, analog door card + bus card, Xiaomi smartwatch has always been the best in the same kind, the company access control card is written in it, the operation is simple and direct.

Built-in six-axis sensor

The Mi band 4 itself has become thicker, and from the back, its sensor is obviously more than the previous generation. According to the official introduction, this smartwatch has a built-in six-axis sensor that can monitor a wider variety of sports. For example, swimming, indoor running, cycling, etc., the swimming also focused on the introduction, because with the sensor, can identify 12 kinds of strokes, and even calculate the average stroke time, distance and so on. The sport function is enhanced by the six-axis gyroscope.

Other changes about Xiaomi Mi Band 4

There are also some invisible improvements, such as the Bluetooth standard upgrade from 4.2 to 5.0, the latter communication speed of up to 2Mbps, 1Mbps higher than the former, and lower power consumption. So although the 4th generation has a color screen, more sensors, etc., its battery is still small, only 125mAh, slightly higher than the 110 ampere of the 3rd generation; Under the use scenario, about 50 WeChat notifications per day, heart rate detection is automatic, comprehensively calculated, about 10% of the electricity consumed every day for 7-10 days.

The Mi band 4 is a huge upgrade from the past. It can be said that except for the wristband, all other parts have changed. Its pricing is 169 RMB / 229 RMB, corresponding to the normal version and the NFC version.

We recommend to buy the latter, multiple NFC, the experience of driving and access control card in the future is completely different, more than 60 RMB is very worth.
