How to clear your Android phone cache - and why it greatly improves performance

What is cache?

Think of cache as temporary files, such as images, scripts, and other resources, that help apps and websites load faster. Clearing cache removes those temporary files from your device without affecting your personal app settings or login credentials.

How often should I clear cache?

Whenever you notice your Android device acting sluggish. For most users, every few months is sufficient.
