Solution:
Xiaomi mobile phones all use high-standard screens. Due to the complex outdoor scenes, as the brightness of the screen increases, the temperature will increase. At the same time, the outdoor environment temperature is higher in summer, especially in the environment of direct sunlight, the mobile phone is more likely to heat up. If you use it outdoors and not in a fixed location, it may also cause some power consumption and temperature rise as the signal strength of the mobile network changes. Therefore, when you use it outdoors, try to avoid prolonged direct sunlight, reduce the highlighting time, and ensure a better outdoor experience.
