The Mi Band 4 is now in its 4th generation which is equipped with an AMOLED color touch screen with a diagonal 0.95 inches and 120 × 240 pixels resolution. It uses 2.5D thick scratch-resistant glass. So, it brings a slightly larger display than the Mi Band 3, as well as the choice of one of the 77 available faces.
Unlike the previous generation, the Mi Band 4 also brings improvements to the sporting activity and can now be used for swimming. It is water resistant – 50 meters deep and 5ATM pressure. In addition, it also integrates a microphone through which you will be able to control by voice commands both the bracelet and any IoT equipment. However, I tend to believe that this option will be available only to China, because the voice assistant uses the Xiao AI virtual assistant.
The rest of the options (notifications, music control, etc.) that we find in Mi Band 3 are still available here. Mi Band 4 also comes with a slightly larger battery, with a capacity of 135mAh, which should ensure a range of up to 20 days, which is similar to previous generations. The bracelet is available in 2 versions: standard and with NFC.
