Design and display

The compact design of the previous Mi bands remains true to Xiaomi. The Bracelet Made of TPU, 18 mm is wide and adjustable in size between 155 - 216 mm. A pin buckle holds the bracelet firmly on the wrist. Practical is the identical bracelet size to the Mi Band 3. Who wants to change from the predecessor to the new Mi band, can use his old bracelet also with the Mi Band 4!

Mi Band 4 capsule with TPU strap

New is the 0.95 inch large touch display. This is of the type AMOLED and now also represents colors (24bit). The high resolution of 240 120 x pixels ensures a crisp, sharp image with a low display diagonal. Special features of the AMOLED are the particularly strong colors and the almost infinite contrast. When black is displayed, the pixels that light up are simply turned off. As a practical side effect, the energy consumption of the panel is reduced.

Tracking unit with OLED color display and backside heart rate sensor

By the high Display brightness of 400 Nit The display remains very readable even in the sunshine. Overall, 5 brightness levels are available. What the display unfortunately misses is an automatic brightness adjustment. The panel is protected by a hardened protective glass. The 2.5D Curved Cut ensures rounded edges and a better look. The capsule-shaped tracking unit is removable and is connected via a 2 pin connector loaded. The charging pins are now on the bottom, so that the charger of the predecessor in contrast to the bracelet is not compatible! The fitness bracelet is waterproof to 5ATM (50 meter) and can therefore be easily worn while swimming.

Processing and delivery

At the quality of workmanship there is nothing to complain about. The Mi Band 4 is expected to be well processed. Even after repeated removal, the inlet of the tracker and the shutter will not let up. The comfort is excellent. The Scope of delivery includes the TPU wristband, tracking unit, USB charging adapter, and instruction manual.

Xiaomi Mi Band 4 features

Better tracking and new sports modes

The 6 Axis Motion Sensor (3 Axis Accelerometer + 3 Axis Gyroscope) gives the Mi Band 4 new possibilities to track an even wider range of sports. Overall, stand 6 sports to select. In addition to running, treadmill and walking, there are cycling, swimming and free training. All training sessions can be started directly from the smartband. On PPG sensor measures the heart rate of the user. This even works pretty well and provides even in the high pulse range still reasonably comprehensible results.

No GPS, but MiFit GPS

A GPS module is not installed. Instead, the GPS of the connected mobile device can be used for a more accurate tracking. But even without GPS delivers the Pedometer extremely precise results. Depending on the sport, the following data is collected, among others:

  • Elapsed time
  • steps
  • Removal
  • calorie consumption
  • Geschwindigkeit
  • stride
  • heart rate
  • height difference
  • Performance VO2Max
  • Swolf
  • beat number

All data will be sent by Bluetooth 5.0 BLE transferred to the MiFit app and can be viewed in edited statistics. In addition to the edited display of all sports data, the MiFit is the control center of the Mi band. Settings for the bracelet, the notification reception, the weather or the alarm clock can be made directly via the app.

More than 53 Watchfaces

To customize the user interface, Xiaomi is the same 53 different watchfaces to select. The high-resolution AMOLED display offers new possibilities to display even more unusual watchfaces. In addition to time, date and steps, animations can also be displayed.

Especially interesting is the possibility to develop your own Watchfaces for the Mi Band. Own creations or watchfaces from the community can be loaded via app (MiBand4 - Watchface) directly onto the bracelet.

Language Assistant and NFC

!! The following applies exclusively to the Chinese version of Mi Band 4 !!

In China, the NFC model supports the Xiao AI language assistant. The Xiao AI is indeed equated with "Western" language assistants like Google Voice, Alexa or Siri understands so far but only Chinese, and is therefore of interest only to the Chinese users.

To what extent the Xiaomi Mi Band 4 will receive a Western language assistant remains to be seen. The Xiaomi company Huami has a close relationship with the Amazfit Verge already made. Instead of the Xiao AI, the international model of the Smartwatch with Amazon Alexa has appeared. The NFC function is also denied to the Chinese market, so that mobile payment with eg Google Pay is not possible!

Notifications, music control and more

In addition to sports functions, the Mi Band 4 also offers other functions that make everyday life easier for the user. Incoming on the smartphone App and call notifications can be displayed directly on the fitness tracker. For example, if you receive a WhatsApp message, you can retrieve it via the bracelet. However, it is not possible to reply to messages or SMS!

Summary

Also interesting are the new sports modes. With the sport mode "swimming" and the 5ATM waterproofness, users also get far-reaching possibilities of use in the water. The battery life is still very good with realistic 16 days. Overall, the Xiaomi Mi Band 4 is unreservedly recommended!
