Is cached data important? Cached data isn't inherently important, as it's only considered “temporary storage.” However, it does exist to improve the user experience. On-page elements like images, videos, and even text take some time to load.
Is it OK to delete cache files?
Clearing unused cache files on Android is a decent way to free up space temporarily and comes in handy when troubleshooting app issues. But it's not something you should do often, or through unreliable third-party apps. Use it only as a specific tool when needed for device performance.
What will happen if I delete cached data?
The application stores more vital information like user settings, databases, and login information as data. When you clear the data, both the cache and data are removed. Clearing data is the equivalent of starting an app from a clean slate as if you just installed it for the first time.
