The Display

The Mi Band 4 maintains the OLED technology of its predecessors but with a significant upgrade. Last year’s Mi Band 3 features a 0.78 inch OLED display with 80 x 128 pixels resolution. But this year, Xiaomi takes it a step further, featuring a 0.98 inch AMOLED display with 120 x 240 pixels resolution on the Mi Band 4. Data can easily be viewed on the Mi Band 4 which is critical in fitness smartwatches.

For personalization, the Mi Band 4 comes with 77 colourful dial themes and eight different brands. The wrist band measures 18mm and it’s removable as we have seen on other Mi Bands.

The Mi Band 4 comes with a 5ATM water-resistant rating. This means you can take the smartwatch to a pool of water measuring 50 metres depth. Also, the device can track your swimming activity in a pool. It won’t be able to track your activity on open water like a beach. There are Black, Brown, Blue, Pink and Orange body colours to choose from.

5ATM Water Resistant Rating


One of the things that set the Mi Band 4 apart from many other feature-laden smartwatches available is its 5ATM water-resistant rating. It can withstand pressures equivalent to a depth of 50 meters, making it a charm when being exposed in rain, splashing, accidental submersion, showering, surface, swimming.

The Mi Band 4 shows if there is an incoming call as well as the caller ID once you are connected to your phone Bluetooth. It also shows all your app notifications once this is activated and synchronized to the watch.
