How does Apple 6s clear the copied information?

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 "horizontal circle in red circle" in the upper left corner of the icon to delete the background running software, and then press the Home button to reply. Deleting background running programs will help improve the running speed of iPhone and save power and traffic.

There are many junk files in the system. Basically, the system used by the iPhone will not leave too many junk files, but if you find that the iPhone is occupied by junk files, it is recommended to refresh or upgrade the system correctly to remove the junk.

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

4 If your iPhone is never turned off, there is another way to clean up junk and redundant files, and that is to restart your Apple iDevice (all devices in the iOS system should be the same), which is very important for regular maintenance of devices.
