🔍 What Is Cache?

Cache is temporary storage that apps and systems use to store frequently accessed data. For instance, Instagram may cache photos or layout data so the next time you open the app, it loads faster.

Simple Examples:

  • When visiting a website again, the browser loads it faster using cached files.

  • Apps like WhatsApp store media previews in the cache so you don’t re-download every time.

🎯 Functions of Cache

  1. Faster App Loading

  2. Saving Internet Data

  3. Improved User Experience

  4. Reduced CPU and RAM Load

But too much cache can slow down your phone, take up storage, and cause errors.

⚠️ Risks of Not Clearing Cache

  • Storage fills up quickly

  • App crashes or slowdowns

  • Errors during updates

  • Phone heats up faster
