Clearing a device’s cache does not automatically improve performance and can sometimes make apps or websites temporarily slower. Caches store reusable data so software does not need to download or recreate it repeatedly, meaning routine deletion removes a shortcut that normally speeds up everyday use.

Clearing cached files can help when specific stored data is corrupted, causing loading or formatting problems, or when storage space is urgently needed. Browser, app and system caches serve different purposes, so the article advises targeted troubleshooting—such as clearing an affected Android app’s cache or the PS5 system cache—rather than treating cache clearing as regular maintenance.
