If the APPs are removed from the background of the POCO F7, please refer to the following explanations:
1. When multiple APPs are running simultaneously in the background, the system's available RAM gradually decreases as more memory is consumed;
2. To maintain smooth performance and responsiveness, the phone automatically removes certain background APPs to free up sufficient RAM for active tasks. This memory management strategy helps prevent lag or slowdowns during daily use;
3. To reduce the frequency of APPs being automatically closed, it is recommended that you regularly clear or close background APPs that are used less frequently, which not only optimizes memory usage but also helps improve overall system stability and battery efficiency.
