Xiaomi Mi Band 4 offers a color screen and monitors heart rate.

The smart gadget provides a colored, touch screen AMOLED  with a diagonal of 0.95 inches, a resolution of 120 × 240 pixels, and a brightness of 450 nits. The user-friendly interface provides a smooth and simple touch screen experience. There is also a brightness adjustment mode, and the tempered 2.5D glass has a coating against fingerprints.

Mi Band 4 includes several sports modes available from the Mifit APP mobile application for various activities – such as treadmill, outdoor running, climbing, and brisk walking. By simply lifting the wrist, the user can check the display of the bracelet indicators such as distance traveled, heart rate, speed, and other important data.

 Mi Band 4 is a stylish bracelet with a user-friendly interface

The smart bracelet works in tandem with the smartphone, thanks to the wireless Bluetooth connection. This ensures that its holder will not miss an incoming call – if there is one, the caller ID is immediately displayed on the bracelet display. Almost all notifications in the mobile application can be synchronized with the smartwatch.

Moreover, Xiaomi Mi Band 4 supports several pages for messages from the smartphone, in case their content is longer. The smart bracelet allows checking the last 5 messages and if their text exceeds the size of the display, with the touch of a button the user can go to the next page – 3 pages are supported.

Xiaomi Mi Band 4 is an invaluable assistant in sports.

The modern user interface offers more convenience for users. For example, lifting the wrist – without touching the screen – is a sufficient gesture to “wake up” the smart bracelet so that one can see in real-time on the display its sports performance – time, heart rate, and other data.

Xiaomi Mi Band 4 helps its owner to measure and store valuable information about all their activities during the day – including, calculate the distance traveled, as well as calories burned, take care of your health, and monitor your sleep. In addition, the smart bracelet reminds when it’s time to rest.

 Mi Band 4 also takes care of its owner’s vacation

And a particularly important feature, without which the smart bracelet would not be complete. This smart gadget is able to constantly monitor your heart rate 24 hours a day. Heart rate recording starts automatically each time the smart bracelet is turned on.

Xiaomi Mi Band 4 is a durable device. One charge of the battery provides the smart bracelet with about 20 days of standby time. It is also very light – it weighs only 22.1 grams. It is available in different colors, along with the strap, power cord, and user guide.
