Mi Smart Band 4 is an affordable fitness band from Xiaomi. With this, the fourth iteration of the Mi Band, Xiaomi has introduced a colour display and swim tracking, and still claims to offer 20-day battery life. The Mi Band lineup began with a product that didn't even have a display and now we get a device with an AMOLED colour display and lots of watch faces, which are nice to have. The Mi Smart Band 4 costs a little more than the Mi Band 3, but are its new features worth the asking price? We used it for a week to find out.
