What clearing cache does and why you might need to

Cache is temporary data your tablet stores to load apps and websites faster the next time you use them. Over time, cached files pile up and can slow your device, cause apps to crash, or use storage space you need for other things. Clearing cache does not delete your passwords, photos, or documents — it only removes those temporary files.

Most tablets benefit from a cache clear every few months, or sooner if you notice apps freezing, websites loading slowly, or storage warnings. The process takes a few minutes and works the same way whether you use an iPad, Samsung Galaxy Tab, or Android tablet.

Key Takeaways

  • Cache is temporary data apps and websites store on your tablet to load faster; clearing it frees up space and can fix slow performance without deleting your personal files.
  • On iPad, go to Settings > General > iPad Storage, select an app, and tap Delete App, then reinstall it to clear its cache without losing your data.
  • On Android tablets, open Settings > Apps, select an app, tap Storage, and choose Clear Cache to remove temporary files when ready.
  • Clearing your browser cache (Safari, Chrome, or Firefox) removes stored website data separately from app cache.
  • You can also clear all cache at once on Android by going to Settings > Storage > Cache and selecting the option to clear it system-wide.

How to clear cache on an iPad

iPad does not have a single "clear cache" button like Android tablets do. Instead, you clear an app's cache by offloading or deleting and reinstalling the app. Offloading removes the app but keeps your data; reinstalling removes everything and downloads it fresh.

To offload an app: Open Settings, tap General, then iPad Storage. Scroll down and select the app you want to clear. Tap Offload App, then confirm. The app icon stays on your home screen but the cached data is gone. Tap Reinstall App to read it again without losing your account information.

To delete and reinstall instead: In iPad Storage, select the app and tap Delete App. Confirm the deletion. Then open the App Store, search for the app, and tap Get to reinstall it. This removes all cached data and any app-specific settings, so use this method only if the app is misbehaving badly.

How to clear cache on an Android tablet

Android tablets have a built-in cache-clearing tool that works for individual apps or all apps at once. The fastest way is to clear cache for one app at a time when you notice it slowing down.

To clear cache for a single app: Open Settings and tap Apps (or process Manager, depending on your tablet brand). Find the app in the list and tap it. Select Storage, then tap Clear Cache. The app stays installed and your account data remains; only the temporary files are removed. You can do this for as many apps as you want.

To clear all cache at once: Open Settings and tap Storage (or Device Care on Samsung tablets). Look for Cache or Cached Data and tap it. Select Clear Cache or Delete. This removes temporary files from every app in one action. It takes a minute or two depending on how much cache has built up.

Clearing browser cache on Safari, Chrome, and Firefox

Website cache is separate from app cache. If websites are loading slowly or showing outdated information, clear your browser's cache instead of clearing app cache.

On Safari (iPad): Open Settings, scroll down and tap Safari, then tap Clear History and Website Data. Choose a time range — Last Hour, Today, Last Week, Last Month, or All Time — and tap Clear. This removes browsing history, cookies, and cached website files.

On Chrome (iPad or Android): Open the Chrome app, tap the three-line menu (top right), select Settings, then Privacy. Tap Clear Browsing Data. Check the boxes for Cookies and Site Data and Cached Images and Files, choose a time range, and tap Clear Browsing Data.

On Firefox (iPad or Android): Open Firefox, tap the menu (three lines, bottom right), select Settings, then Data Management. Tap Clear Private Data, check the boxes you want, and tap Clear.

When to clear cache versus when to clear storage

Cache and storage are not the same thing. Cache is temporary files that apps and websites create automatically. Storage includes everything on your tablet — apps, photos, documents, videos, and cache all together.

Clear cache when an app is slow, crashing, or using too much space, or when a website is not showing current information. Clear storage only when you need to delete actual files like old photos or unused apps. If your tablet is running out of storage, check your Photos app and Downloads folder first; those usually hold the most space.

You can see how much cache each app is using in Settings. On iPad, go to Settings > General > iPad Storage and look at the size listed under each app. On Android, go to Settings > Apps, select an app, tap Storage, and you will see App Size and Cache Size listed separately. If an app's cache is several hundred megabytes, clearing it will noticeably free up space.

What happens after you clear cache

After clearing cache, apps will take a few seconds longer to open the first time because they have to rebuild their temporary files. Websites will load slightly slower on your first visit because the browser has to read images and data again instead of using stored copies. This slowness lasts only a few uses; after that, your tablet will feel faster because it is not juggling old cached files.

You will not lose any of your settings, passwords, photos, documents, or app accounts. The only things removed are temporary files that your tablet can recreate on its own. If an app stops working after you clear its cache, reinstalling it from the App Store or Google Play will fix it.

Frequently Asked Questions

Will clearing cache delete my passwords or login information?

No. Cache is only temporary files. Your passwords, usernames, and saved account information are stored separately and will not be affected. You may need to log in to apps once after clearing cache, but your account data stays intact.

How often should I clear cache on my tablet?

Once every few months is normal for most users. If you notice your tablet slowing down, apps crashing, or storage running low, clear cache sooner. Heavy users who install many apps or browse constantly may benefit from clearing cache monthly.

Can I clear cache without deleting app data?

Yes. On Android, tapping Clear Cache removes only temporary files and leaves your app data, accounts, and settings alone. On iPad, offloading an app does the same thing. Only if you delete and reinstall an app will you lose app-specific data.

What is the difference between clearing cache and clearing browsing data?

Cache is temporary files stored by apps and websites. Browsing data includes cache plus your browsing history, cookies, and saved passwords. Clear cache to speed up apps; clear browsing data when you want to erase your web history as well.

Will clearing cache make my tablet faster?

It can. If cache has built up to hundreds of megabytes, clearing it frees storage space and can reduce lag. The effect is most noticeable on older tablets or those running low on storage. On newer tablets with plenty of free space, you may not notice much difference.
