What cache is and why you should clear it

Cache is temporary data your tablet stores to load apps and websites faster. When you open an app or visit a website, your tablet saves images, text, and other files so it doesn't have to read them again the next time. Over time, this cache builds up and can slow your tablet down or use storage space you need for other things.

Clearing the cache doesn't delete your passwords, photos, or personal files — it only removes those temporary copies. Think of it like emptying a junk drawer that's gotten too full. Your tablet will work normally afterward; apps and websites will just take a moment longer to load the first time you use them again.

Key Takeaways

  • Cache is temporary data stored by apps and browsers to speed up loading; clearing it frees up storage without deleting your personal files.
  • On iPad, clear app cache through Settings > General > iPad Storage, then select each app and choose "Offload App" or delete and reinstall it.
  • On Android tablets, go to Settings > Apps, select an app, then choose "Storage" and tap "Clear Cache" (not "Clear Data").
  • To clear browser cache on iPad, go to Settings > Safari and tap "Clear History and Website Data"; on Android, open your browser settings and find the cache or history option.
  • You can clear cache monthly or whenever your tablet feels slow, with no risk to your saved passwords or files.

Clearing cache on an iPad

On iPad, you clear cache through the Settings app. Open Settings, then tap General. Scroll down and select iPad Storage (the name varies slightly by iPad model, but it's always in General). You'll see a list of your apps sorted by size.

Find the app whose cache you want to clear and tap it. You'll see two options: Offload App and Delete App. Tap Offload App — this removes the app but keeps your data inside it, so you won't lose saved games, settings, or documents. The app will reinstall itself the next time you open it, and the cache will be cleared. If you want to be thorough, you can delete the app entirely and reinstall it from the App Store, but offloading is faster and safer.

To clear your Safari browser cache specifically, go to Settings > Safari and scroll down to find Clear History and Website Data. Tap it and confirm. This removes cached web pages, cookies, and browsing history all at once.

Clearing cache on an Android tablet

On Android tablets, open the Settings app and go to Apps (sometimes called Applications). You'll see a list of installed apps. Tap the app whose cache you want to clear.

Inside the app's settings page, look for Storage or Storage and Cache. Tap it, and you'll see two buttons: Clear Cache and Clear Data. Tap Clear Cache only — do not tap Clear Data, which removes saved passwords and settings inside that app. After you tap Clear Cache, the temporary files are gone.

To clear your browser cache on Android, open your browser app (Chrome, Firefox, or whatever you use). Tap the menu button (three dots or lines in the corner), then look for Settings or History. Find the option that says Clear Browsing Data or Clear Cache, select it, and confirm.

Clearing all cache at once

If you want to clear cache from multiple apps without doing them one by one, both iPad and Android offer a faster route. On iPad, go to Settings > General > iPhone Storage (or iPad Storage), and you can offload several apps in a row by tapping each one and selecting Offload App.

On Android, go to Settings > Storage or Device Care (the exact name depends on your tablet brand). Look for an option like Clean Up, Optimize, or Storage Manager. Tap it and select Clear Cache or Delete Junk Files. This clears cache from all apps at once without touching your personal data.

When to clear cache and how often

You don't need to clear cache on a schedule. Clear it when your tablet feels slow, when you're running out of storage space, or when an app is behaving strangely. For most people, clearing cache once a month is enough. If you use your tablet heavily or install many apps, you might clear it more often.

If clearing cache doesn't speed up your tablet, the problem may be something else — too many apps running at once, a full storage drive, or an app that's using too much memory. In that case, restart your tablet (turn it off and back on), uninstall apps you don't use, or check your storage to see what's taking up the most space.

What cache clearing does and doesn't do

Clearing cache removes temporary files only. Your passwords, saved logins, photos, documents, email, and app data stay on your tablet. You won't be logged out of apps or websites unless you also clear cookies or data (which you should not do unless you want to). The first time you open an app or website after clearing cache, it may take a few seconds longer to load because your tablet has to read those temporary files again.

Clearing cache is safe and reversible. If you clear cache and then realize you didn't want to, there's nothing to undo — your tablet will straightforward rebuild the cache the next time you use each app or website. You can clear cache as often as you want without any risk.

Frequently Asked Questions

Will clearing cache delete my photos or documents?

No. Cache is only temporary data used to speed up loading. Your photos, documents, emails, and all personal files stay on your tablet. Clearing cache only removes files your tablet created automatically, not files you created or saved yourself.

What's the difference between clearing cache and clearing data?

Cache is temporary files; data is your settings, saved games, and login information inside an app. Clear cache when you want to free up space. Clear data only if you want to reset an app completely, which will log you out and erase any saved progress. On most tablets, you should clear cache, not data.

Why is my tablet still slow after clearing cache?

Cache is only one reason a tablet slows down. If clearing cache doesn't help, restart your tablet, close apps you're not using, or check how much storage space is left. If your storage is nearly full, your tablet will run slowly no matter how much cache you clear. You may need to delete large files or apps you don't use.

Do I need to clear cache before selling or giving away my tablet?

Clearing cache alone is not enough. Before selling or giving away your tablet, you should do a factory reset (also called a hard reset or erase), which removes everything — all apps, files, and settings. This is different from clearing cache and is the only way to make sure your personal data is gone.

Can I clear cache for just one app without clearing it for all apps?

Yes. On both iPad and Android, you can clear cache for individual apps by going to that app's storage settings and tapping Clear Cache. You don't have to clear cache for everything at once unless you want to.
