Accordingly, instruction manuals and other product information are in Chinese only. A global sale of the Mi Band 3 is not yet apparent.

Scope of delivery of the Mi Band 3


The Xiaomi Mi Band 3 is an app-controlled smartband. For an extensive use the so-called Mi Fit App needed. The app is free and can be used both for Android as well as for iOS be downloaded in the respective app stores. As minimum requirement needs the app Android> 4.4 or iOS> 9.0 mobile device with Bluetooth 4.0 Support. The connection between mobile device and smartband is via Bluetooth. For this is the Mi Band 3 with a Bluetooth 4.2 BLE (Low Energy) Module equipped.

Wristband and tracking unit of the Mi Band 3

The use of the Mi Fit app requires one user account, which can be directly applied via the app. With this user account all stored data of the Mi band are synchronized. The setup and connection of the smartband is uncomplicated and in just a few steps via the app.

App and features


The Mi Band 3 firmware was released in Chinese only. Meanwhile, updates have been released, which include a English and Spanish language settings enable. Do you want one German user interface, you have to modified community firmwares fall back on. The user interface is now officially available in German! Firmware updates are received via the Mi Fit App and automatically uploaded.

Pedometer and activities

Smartband and App offer a variety of sports features. For movement detection, the bracelet is with a Pedometer fitted. Once you have set an individual daily goal, you can start. In addition to the everyday steps The bracelet also determines the covered track and guess the burned calories.

If you synchronize the data with the Mi Fit app, you will get a detailed overview of all measured data. The stored data can be stored in Daily, weekly and monthly show with corresponding diagram. There are several ways to increase motivation Daily goals and awards.

Display (1)

Within the Mi Fit app are additional Activity programs (running, treadmill, cycling and walking) to select. Activities can only be started via the app. When an activity is started, the app, wristband, steps, distance traveled, and heart rate are displayed in real time. In addition, the Mi Fit activities use the GPS of the mobile device, which allows a precise route including map view.

The Accuracy of the pedometer is based on the predecessor model. Serious incorrect measurements due to driving or other activities that do not represent a stepping motion did not occur in the test.

Heart Rate Monitor

The heart rate sensor is located on the bottom of the bracelet. The Heart rate measurement is done in a classic way with the help of a Photo diode in combination with a green LED, The blood flow under the skin is measured. However, the accuracy of optical heart rate measurement is critical. measurement error can already occur due to too loose fit of the bracelet, by arm hair or tattoos.

With the Mi Band 3 is one Single and interval measurement possible. The interval measurement measures the heart rate every minute, every 10 minutes or every 30 minutes depending on the setting. A continuous measurement is only possible by starting an activity. The measurement accuracy is highly dependent on the measurement conditions. In addition to predominantly plausible measurement results, measurement inaccuracies can occur, especially in the higher pulse range or in diversified activities. The recorded data can be synchronized with the Mi Fit App as well as the movement data and displayed in a detailed diagram view.

Sleep monitor and alarm clock

The sleep monitor rates sleep according to an 100 scoring system. The are measured Falling and waking time, the Time of total sleep, Tiefschlaf, light sleep and the waking hours, To display the collected data, the Mi Fit app has to be used again. This reproduces the measured data to the minute in the detailed bar chart. At the same time, based on the measured data, a Sleep quality analysis (see pictures).

A manual start of the sleep monitor is not necessary and not possible. Instead, the Mi Band 3 recognizes the time of falling asleep with the help of the built-in acceleration sensor, Unfortunately, the sleep detection is based on the system time of the mobile device, so that a sleep monitoring during the day is not possible. The accuracy of the data acquisition has convinced in the test. Falling in and waking time are detected quite accurately. To increase the accuracy again, the "Sleep Wizard" to be activated. This allows (to the detriment of the battery) continuously determined heart rate data to flow into the sleep rating.

With the publication of the Xiaomi Mi Band 2 barely two years ago, the Mi Fit app contained one more Sleep.Phase.Alarm.Clock, This has now been removed from the app. An alarm clock with Snooze is still available. On the basis of create wake-up profiles, it wakes at pre-set times by gently vibrating. The vibration intensity and the vibration pattern can not be adjusted.

The Xiaomi Mi Band 3 is capable of receiving incoming notifications on the mobile device. Next Phone and SMS alerts can also App notifications received and displayed. For example, if a WhatsApp message arrives on the connected mobile device, it will be sent to the Mi Band. In the absence of German language support, umlauts are not displayed correctly! Notification receipt can be configured extensively via the Mi Fit app.


Another feature is the weather function. This will be displayed Daily weather with highest and lowest temperatures, as well as one 2-day weather forecast, The weather data is obtained from the bracelet via the Mi Fit app. The location for weather data collection can be adjusted within the app. From which provider the data comes, does not emerge from the app.

Hello team, great review, which I can agree with. I've been using my Mi Band 3 for 2 weeks and would like to change the language to German. You write that it is possible. Can I simply play any firmware from the net or do I have to pay attention to the version number? I already know how to do that. And what about the MiFit app when it receives an update. Will my bracelet be dubbed?


Hello team
Very good idea of ​​the tracker which coincide with my experience with the device.
But can not understand why the tracker sleep should not capture the day? I work in 3 shift service and each sleep is reliably recorded no matter what time, even short sleep intervals of 45 minutes are randomly distributed throughout the day


One of our two copies of Mi Band 3 is leaking. After a few minutes showering, the smaller characters in the display were barely visible.
So it is not even resistant to jets of water according to IP 65.
Allegedly, the tape can submerge 30 minutes and tolerate pressure from 5 ATM.
The dealer makes a circus because of the warranty. The clear photos of the display with water droplets inside, he allegedly did not receive, to gain more time, six more photos were requested from all sides of the tracker.
