The Mi Band is mainly used for fitness and exercise tracking, and its screen and features are limited, so it does not support playing games and reading novels. Its main function is to display basic information such as time, steps, heart rate, etc., and can be used in conjunction with mobile phone apps for more detailed health and exercise data analysis. If you need to play games and read novels, it is recommended to use a device that is more suitable for these functions, such as a smartphone or tablet.
