A few days ago, the latest smart bracelet, Xiaomi Mi Band 4 has been launched. Xiaomi Mi Band 3 is very well reviewed, the upgrade attracts extensive attention. Let’s check it out.
Xiaomi Mi Band 4 offers five color variants, which are Black, Orange, Blue, Claret and Pink. We got the Black color variant.
The design of Xiaomi Mi Band 4 is similar to Xiaomi Mi Band 3, including the display and the wrist strap.
The wrist strap still adopts the TPU material, but I think it is not easy to wear.
Compared with Xiaomi Mi Band 3, the Home button on the display is changed to flat.
Xiaomi Mi Band 4 comes with a 39.9% bigger display and is now using AMOLED color screen, and there’s even 2.5D scratch-resistant tempered glass on the top. Also, the resolution ratio is higher than Xiaomi Mi Band 3.
With the bigger display and higher resolution ratio, the Xiaomi Mi Band 4 can show more details. What’s more, the display of Xiaomi Mi Band 4 is brighter than Mi Band 3, when I play outdoor games, I can see the details showing on the display clearly.
Xiaomi Mi Band 4 is built-in 77 themes, such as Overwatch, Ali the fox, Luo Xiaohei and so on.
Xiaomi Mi Band 4 mainly provides the function of notification, swiping cards and sports health. All functions need to be used by Mi Fit.
The notification feature consists of calls, message, reminders and other frequently-used applications. Users can choose whether or not to reply the calls by Xiaomi Mi Band 4.
For me, I turn on the notification of calls and some applications. This feature is easy for me to not miss the important calls.
Xiaomi Mi Band 4 has an NFC variant, so it can be used as a traffic card and an entrance card. What’s more, it can also work with Xiaomi Mijia smart door locks.
With the high resolution ratio, Xiaomi Mi Band 4 also supports Alipay with QR code.
Sport tracking is the main features of Xiaomi bracelet, which can figure steps and calories up. For Xiaomi Mi Band 4, it can monitor 6 sport modes, such as swimming, indoor running, outdoor running, exercise, cycling and walking. And it is also water resistant up to 5ATM (50 meters) and sports an upgraded 6-axis high-precision sensor to intelligently recognize different type of swimming strokes including Freestyle, Backstroke, Butterfly stroke, and Medley.
Xiaomi Mi Band 4 can accurately record information about sleep quality every night, including data on deep sleep and light sleep. The details can be checked on Mi Fit.
I have not always turned on the heart rate monitoring feature because of the high power consumption, which will reduce the battery life.
As the bigger and color display, Xiaomi Mi Band 4 is fueled by 125mAh battery, which is better than predecessors. And the weight of monitor is 10.7g, which is heavier than Xiaomi Mi Band 3.
In addition, Xiaomi Mi Band 4 and Xiaomi Mi Band 3 can use the same wrist strap, but they can’t use the same charger.
Although the charging contact has been placed at the rear side of the monitor in the Xiaomi Mi Band 4, it still needs to take out the monitor to charge.
Xiaomi’s AI assistant, called Xiao Ai, is installed in the Xiaomi Mi Band 4. Although Xiao Ai is not capable of speaking in Xiaomi Mi Band 4, but it can shows the information on the display.
The users need to swipe the screen to wake up Xiao Ai. Xiao Ai can also work with IoT devices. You can call Xiao Ai to turn on the light or fan.
The users need to swipe the screen to wake up Xiao Ai.
Compared with Amazfit smart watch, the Xiaomi Mi Band 4 is a good chance for most of people to get more information about Xiao Ai and Mijia products.
Conclusion:
From Xiaomi Mi Band to Xiaomi Mi Band 4, the screen gets bigger and bigger. I deem that Xiaomi may design a full screen smart bracelet in the future.
