Thank you for being so supportive of Xiaomi products.
Cold Start on a mobile phone refers to the situation where an APP runs for the first time after the phone is started, or when the APP process is terminated and restarted. In this case, the APP process does not exist, so the system needs to create a new process and initialize the APP.
This mobile phone has a small memory, and when it is used for a long time or when the phone opens many applications, it will experience lag. To improve performance, it's essential to clean the memory promptly. Closing unused APPs and clearing cached data can help free up resources and speed up application launch times, ensuring a smoother experience.
