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.

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.
