After trial, the functions and performance of Xiaomi Mi band 4 can compete with Fitbit inspire HR in all aspects, and its battery life performance is even stronger. It is worth mentioning that MI band 4 is compatible with Android smartphones and iPhones.
Xiaomi Mi band 4 has built-in heart rate sensor, supports GPS global positioning system, and has a large number of surface options. If you are happy to use Mi fit app of Xiaomi to view your fitness data, MI band 4 of Xiaomi is still worth your purchase.
The features of color display, GPS connection, water resistance, heart rate sensor and decent battery life make Mi band 4 the best low-cost fitness tracker at present.

Xiaomi Mi band 4 screen and shape design — mediocre appearance
Before Mi band 4, Xiaomi has launched three versions of MI band, which have won the favor of a large number of consumers with their affordable price, ultra-thin appearance and excellent functions. Obviously, MI band 4 is Xiaomi’s latest and best fitness tracker so far, and its cost performance is very high.
The shape design of MI band 4 is not particularly exciting. Its shape is very simple. It is equipped with a Black Silicone Tape and a small pebble shaped tracker embedded in the middle. Xiaomi Mi band 4 allows users to change the watch strap at will and charge through its special charging bracket.
The small fitness tracker comes with a 0.95 inch capacitive color touch screen, heart rate sensor, main button, 5-atm waterproof, 512MB memory, accelerometer and gyroscope. Once the device is recharged and embedded in the strap, it’s a wrist tracker. Sometimes you may forget that you are wearing the MI band 4, which weighs only 22.1 grams.
It is worth noting that the display of MI band 4 is difficult to read in direct sunlight. But beyond that, the design of MI band 4 is almost impeccable – once you wear it, it will start tracking everything.
Mi band 4 activity and exercise tracking
Mi band 4 provides you with many functions, such as step tracking, calorie consumption, driving distance, heart rate and sleep tracking. It will automatically collect these data without even requiring you to interact with the device.
In addition, MI band 4 also supports the exercise mode that must be triggered manually. It does not support the automatic exercise detection function like the more expensive fitness tracker. Compared with the previous generation of products, the exercise mode of MI band 4 is an upgrade in itself. You can set them from the MI fit application.
If you want to run outdoors, please put your mobile phone in your pocket and start running through Mi band, which will connect to the GPS of your mobile phone to track your running route. After running, you can view the route through Mi fit app. At the same time, your speed, average heart rate, stride length, rhythm, frequency division time and other data are recorded.
If you sit in front of your desk for too long, MI band 4 will remind you to stand up and move. At the same time, when your heart rate is higher than the normal level, MI band 4 will also issue a warning (during the Xiaobian test, I didn’t receive this warning, even after exercise).
Mi band 4 supports treadmill, bicycle, walking, weight lifting and other exercise modes. Moreover, because Mi band 4 supports 5-atm waterproof features, it can also track users’ swimming. It can be said that the price performance of MI band 4 is very impressive.
Compared with Samsung Galaxy watchactivity 2 and polar vantage V watch, Xiaobian found that the data provided by Mi band 4 is quite accurate. I suggest you connect your mobile phone’s GPS when you run, because you can get more accurate distance and rhythm readings. Without GPS data, MI band 4 simply relies on guesswork, which leads to inaccurate readings – as is the case with competitors without built-in GPS technology.
After testing, like the 199 pound Fitbit versa 2 and other devices, the 35 pound Mi band 4 can accurately record Xiaobian’s activity and exercise data. Obviously, the price performance of MI band 4 is much higher than that of Fitbit versa 2.
Application and notification of MI band 4 in Xiaomi
One of the disadvantages of MI band 4 is its mi fit application, which is not intuitive enough. Like Google fit, Samsung health or Fitbit apps, the MI fit app can collect data from the MI band fitness tracker and display it in different areas.
The main interface of MI fit application is a very basic overview of all kinds of data. Users can deeply view the historical training and walking data, but its interface is not intuitive enough, resulting in users not knowing how to find them and how to interact. In the process of trying to view all the statistical data, users need to repeatedly try and grope for a long time before they can see the data they need.
When you finally find the statistics you want, the data you read will be very useful. They will specify several indicators of a training.
The MI fit app can be a bit frustrating when the entire function of the fitness tracker is to view your health data. It’s not a big problem if you just want to view your steps and exercise data at will.
Originally, MI fit could link to Google fit to share and display data, but in the test, I couldn’t make it work properly.
It is worth mentioning that MI band 4 has a variety of surfaces to choose from. However, on a screen less than 1 inch, the display effect of these surfaces is very poor.
At the same time, MI band 4 can’t let users interact with their displayed notifications, and users can’t type a reply to the message on the small screen. Xiaomi Mi band 4 can notify you of incoming calls and text messages, as well as selected app notifications (you can select them in the MI fit APP). It’s very convenient if you don’t want every notification from your phone to be sent to your wrist.
Xiaomi Mi band 4 also supports “do not disturb” mode, with alarm clock, stopwatch and music control that can control mobile music player.
Battery life and charging of MI band 4: impressive endurance
Xiaomi claims that the battery life of MI band 4 fitness tracker can reach 20 days. After testing, I found that this number is accurate. On the first day of the test, I charged the MI band 4 from 4% to 100%, and after a week of continuous use, it was 75%. When you train in connected GPS mode, the battery will run out significantly faster.
If you exercise every day, the battery life of the MI band 4 is at least 10 days – in most cases, longer. It seems that the 24 / 7 heart rate monitoring function of MI band 4 will not consume too much power, which is very good.
Finally, Xiaomi Mi band 4 needs a dedicated USB charging base for charging, but this is a common problem of many competitors. Even a 500 pound fitness watch usually comes with a product specific charger, but if you accidentally lose it, you will feel very frustrated.
Is mi band 4 worth buying?
For 35 pounds, you can get a functional fitness tracker. In our actual use, the comprehensive performance of MI band 4 is comparable to that of its more expensive competitors.
If you don’t want to pay for the more expensive Fitbit, then Mi band 4 will be a good choice. I will even recommend it to runners to track their runs, as long as you are willing to use the connected GPS technology with your mobile phone.
One drawback of MI band 4 is its slightly frustrating Mi fit application. In addition, in our test, we were unable to synchronize Mi fit data to Google fit application.
Overall, the color display, GPS connectivity, water resistance, heart rate sensor and decent battery life make the MI band 4 the best low-cost fitness tracker at present.
