Xiaomi Mi Band 3 Review – best fitness tracker under $50


In 2014, Xiaomi announced its first generation sports bracelet called the Mi Band. This band was able to provide some common features in products of this type, such as the pedometer and the alarm, although it was priced at $12, which was an unprecedented amount for a product of this type. Two years later, in 2016, the company arrived with the Mi Band 2, which came with a built-in 0.42-inch screen, many improved features and a price of $22. Thanks to this, we could see that Xiaomi updates its line of smart bands every two years, so the launch of the Xiaomi Mi Band 3 carried out this May 31 was quite expected.

In addition to updating the screen, the chip that is in the Xiaomi Mi Band 3 has also been updated. Even if it has a bigger and brighter screen, this device can still maintain the same battery life that could be seen in the last Mi Band 2, so its update will be accepted in five ways. At the same time, it comes with 5ATM straps that are water resistant, protecting the band even when submerged to a depth of up to 50 meters. Therefore, unlike its predecessors, this can be used when swimming and diving, when in the shower or wherever you want.

The UV100 coating process was applied to the Xiaomi Mi Band 3, and also has an anti-fingerprint coating to increase the wear resistance of its surface. On the other hand, the Mi Band 3 is divided into two versions – one is the standard version, while the second is the NFC version. As its name suggests, compared to the standard version, the NFC version comes with an NFC chip, which is suitable for the type of actions it performs. Finally, this product continues with the high and constant relationship between quality and price that Xiaomi products have, reaching the Chinese market with a price of $25.

Compared to its predecessor, there’s been an upgrade in design, as well as an upgraded OLED panel and NFC. The screen is now bigger compared to the Mi Band 2; the heart rate sensor works fine as well. Let’s find out more, shall we?

The packaging of the Xiaomi Mi Band 3

Well, from what you can see, the package in which the Xiaomi Mi Band 3 comes is standard, and being honest, there are not many things that we can talk about regarding its packaging. Having said that, we will be doing a review of the black color variant of this band, which comes with a user manual and its respective charger cable.

What should be noted about the Xiaomi Mi Band 3 is that due to some frequency problems when updating the screen, it may blink for a moment, which is totally normal. It weighs around 8.5 grams, so it will be able to be used all day without any discomfort.


Apart from the bigger display screen on the Mi Band 3, it sports a heart rate sensor underneath the bracelet. If you wear it all day, you get 24 hours heart rate monitor tracking your health every moment of the day. The heart rate recording starts automatically when you wear it on.

You can now calculate the calories you burn, the distance you work and monitor your sleep. Yes, the Mi Band 3 also reminds you when to have a rest to improve your overall health.

It boasts of Bluetooth v4.2 LE, while connected via the Bluetooth, you can ignore calls or answer them after seeing the caller ID. You will also receive notifications of the device connected via the display.

If you believe that the screen is too small to see and operate, there is the possibility of opening the applications that are needed on your phone to see data in more detail. Also, this band has been updated in terms of heart rate control; During the exercise, if the heart rate is too fast and exceeds the set number, the wristband will vibrate to alert the user of what is happening.

The next amazing feature is the addition of the display of the content in the notifications. This can be configured through the application with which the band can be controlled so that the content of the new messages and others will be displayed on the screen in real time.

Xiaomi Mi Band 3 Findings

The Xiaomi Mi Band 3 version we have is in the Chinese language, and even the manual that came with it was all written in Chinese, so I had to install a modified MiFit APK version on my phone in other to install a patched firmware on your the band. Use on your own risk. You must uninstall the official MiFit application first or the installation will fail (as the keys are different and the APK was resigned with debug keys). After successfully connecting the band to your smartphone, go to Profile > Settings > Check for updates on your phone and it will initiate a firmware update on the Mi Band 3.

After the update is complete, your Mi Band 3 Chinese language will be changed to English. Sounds easy right?

After you update the firmware, you can uninstall the modified APK and install the original one back.

The Xiaomi Mi Band 3 may have been outside the definition of the smart band because, in the traditional definition, a band is not equipped with a screen, because only smartwatches are equipped with the content of the screen. However, there is a tendency to make portable devices easier to use and more convenient, so we can say that the screen is one of the most important updates that the Mi Band 3 has. In short, a Larger screen provides more functions and better use.

On the other hand, it is compatible with a special feature that automatically turns on the display when the user raises wrist, and the band will give information such as the day, time or weather.
