Xiaomi Mi Band 4 review: feature-rich

Smart Device & Safety

Introduction: Xiaomi Mi Band 4 is an excellent, but very cheap fitness tracker, which sells for only $ 32.99, which can be said to be one of the most cost-effective fitness trackers in the current market.

After trial, the function and performance of Xiaomi Mi Band 4 can be comparable to Fitbit Inspire HR in all aspects, and its battery life performance is even more powerful. It is worth mentioning that Xiaomi Mi Band 4 is compatible with Android smartphones and iPhones.

Xiaomi Mi Band 4 has a built-in heart rate sensor, supports GPS global positioning system, and has a large number of surface options. If you are happy to use Xiaomi’s Mi-Fit app to view your fitness data, then Xiaomi Mi Band 4 is still worth buying.

First impression:

Color display, connected GPS, waterproof, heart rate sensor and decent battery life, these features make Xiaomi Mi Band 4 the best inexpensive fitness tracker at present.

Before Mi Band 4, Xiaomi had launched three versions of Mi Band. They have won the favor of a large number of consumers due to their affordable price, ultra-thin form factor, and excellent functions. Obviously, Xiaomi Mi Band 4 is Xiaomi’s latest and best fitness tracker to date, and its price-performance ratio is very high.

The shape design of Xiaomi Mi Band 4 is not particularly exciting. Its shape is very simple. It is equipped with a black silicone band with a small-sized pebble-shaped tracker in the middle. Xiaomi Mi Band 4 allows users to change the strap at will and charge it through its dedicated charging bracket.

This small size fitness tracker is equipped 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 fully charged and embedded in the strap, it is a tracker that can be worn on the wrist. Sometimes, you may forget that you are wearing Mi Band 4, after all, it weighs only 22.1 grams.

It is worth noting that the display of Xiaomi Mi Band 4 is difficult to read in direct sunlight. But beyond that, the design of Xiaomi Mi Band 4 is almost impeccable-once you wear it, it will start tracking everything.

Xiaomi Mi Band 4 provides you with functions such as step tracking, calorie consumption, driving distance, heart rate and sleep tracking. It is quite rich in functions, and it will automatically collect these data without even requiring you to interact with the device.

In addition, Xiaomi Mi Band 4 also supports an exercise mode that must be manually triggered. It does not support automatic exercise detection like the more expensive fitness trackers. Compared to the previous generation of products, Xiaomi Mi Band 4’s exercise mode is an upgrade in itself, and you can set them from the Mi Fit app.

If you want to run outdoors, please put your phone in your pocket and start running through Mi Band, it will connect to the GPS of your phone to track your running route. After running, you can view the route through the Mi Fit app. At the same time, your speed, average heart rate, stride, rhythm, and crossover time are also recorded.

If you sit in front of your desk for too long, Xiaomi Mi Band 4 will issue a reminder to let you stand up and move. At the same time, when your heart rate is higher than normal, Xiaomi Mi Band 4 will also issue a reminder (I did not receive this warning during the Xiaobian test, even after exercise).

Xiaomi Mi Band 4 supports treadmill, bicycle, walking, weightlifting and other exercise modes, and, because Mi Band 4 supports 5-ATM waterproof features, it can also track the user’s swimming. It can be said that the price / performance ratio of Xiaomi Mi Band 4 is still very impressive.

Through the comparison test with Samsung Galaxy WatchActivity 2 and Polar Vantage V Watch, I found that the data provided by Xiaomi Mi Band 4 is quite accurate. I recommend that you always connect the GPS of your phone when you run, because you can get more accurate distance and rhythm readings. If there is no GPS data, Xiaomi Mi Band 4 simply relies on guesswork, which will result in less accurate readings-this is the case with competitor products without built-in GPS technology.

After testing, like the £ 199 Fitbit Versa 2 and other devices, the £ 35 Xiaomi Mi Band 4 can accurately record Xiaobian ’s activity and exercise data. Obviously, the price / performance ratio of Xiaomi Mi Band 4 is much higher than that of Fitbit Versa 2.

One shortcoming in Xiaomi Mi Band 4 is the Mi Fit app it is equipped with, the user interface of this app is not intuitive enough. Like the 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 the Mi Fit app is a very basic overview of various data. The user can drill down to view historical training and walking data, but the interface is not intuitive enough, which makes the user unclear how to find them and how to proceed. Interaction. In the process of trying to view all the statistical data, users need to try repeatedly, and it takes a long time to find out the data they need.

When you finally find the statistical data you want, the data read out will be very useful, they will detail several indicators of a training.

When the whole function of the fitness tracker is to view your health data, the Mi-Fit app can be a bit frustrating. If you just want to view your steps and exercise data relatively casually, then this is not a big problem.

Originally, Mi-Fit can link to Google Fit to share and display data, but in the test, I can not make it work properly.

It is worth mentioning that Xiaomi Mi Band 4 has a variety of different surfaces to choose from, but on a screen less than 1 inch, the display effect of these surfaces is very bad.

At the same time, Xiaomi Mi Band 4 cannot allow users to interact with the notifications they display, and users cannot type replies to messages 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). This is very convenient if you do n’t want every notification of your phone to be sent to your wrist.

Xiaomi Mi Band 4 also supports the “do not disturb” mode, with an alarm clock, stopwatch, and music controls that can control the mobile phone music player.

Xiaomi claims that the battery life of the 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 power of Mi Band 4 from 4% to 100%, and after a week of continuous use, its power was 75%. When you use the connected GPS mode for training, the battery will run out at a significantly faster rate.

If you exercise every day, the battery life of Mi Band 4 is at least 10 days-in most cases, the battery life will be longer. It seems that the 24/7 heart rate monitoring function of Xiaomi Mi Band 4 will not consume too much power, which is still very good.

Finally, Xiaomi Mi Band 4 requires a proprietary USB charging base for charging, but this is a “common problem” for many competitors. Even fitness watches priced at £ 500 usually come with a product-specific charger, but if you accidentally lose it, you will feel very frustrated.
