Should You Clear the System Cache on Your Android Phone?

Some Android phones store temporary files used for things like OS updates in a cache partition. You may have seen recommendations across the web suggesting that you clear this partition from time to time—but is that a good idea?

What Is the System Cache and What Data Is Stored There?

Some time ago, in the days before Nougat, Android used a system cache to store system update files. Android has since moved away from that, preferring a different method for installing updates.

Many modern phones don7;t even have a system cache now. If yours has a system cache, it will be on a separate partition from your primary phone storage. Files stored there don’t take up any user-accessible space2;clearing your system cache won’t allow you to download any new apps, store files, or save more cat photos.

The system cache is also different from cached app data, which is data stored by apps and specific to that particular app. For example, Spotify stores streamed music in its cache file for faster (and offline) playback. Every app has its own cache file which is separate from the system cache file and does take up user-accessible space. Clearing that cache is a great way to free up space2;just keep in mind that the app will rebuild the cache as you use it, so clearing it isn7;t a permanent fix if you need more space.
