What software does Apple mobile phone use to clean up garbage?

Apple's mobile phone uses iOS system, and the system itself has done a lot of optimization on junk files and memory system, so it is not necessary to clean up memory and junk files frequently. However, when you feel that the mobile phone is running slowly, you can consider the following methods to optimize the cleaning.

1. Double-click the Home button below the iPhone to open the background running bar, press and hold an icon in the bar until it shakes, click the symbol number "a horizontal circle in the red circle" in the upper left corner of the icon to delete the background running software, and press the Home button to reply when finished. Deleting background running programs will help improve the running speed of iPhone and save electricity and traffic.

There are many junk files in the system. The system used by iPhone basically won't leave too many junk files, but if it is found that iPhone is occupied by junk files, it is recommended to refresh or upgrade the system correctly to remove the junk.

3. The software can't be opened. It may be that after the system is upgraded, the software does not support the new system, which can be solved by software update.

4. If your iPhone never shuts down, there is another way to clean up junk and redundant files, which is to restart your Apple iDevice (all devices in the iOS system should be the same). Regular restart is very important for maintaining equipment.
