What clearing cache does and why you might do it

Cache is temporary data that apps and Safari store on your iPhone to load faster next time. When you clear it, you delete those stored files — not your photos, messages, or passwords. Your apps and websites will take slightly longer to load the first time after clearing, but they rebuild the cache automatically.

Most people clear cache to free up storage space, fix an app that is acting slow or frozen, or remove browsing history Safari has saved. You do not need to clear cache regularly unless you are running low on storage or troubleshooting a specific problem.

Key Takeaways

  • Clearing Safari cache takes 30 seconds and removes browsing history, cookies, and temporary website data from your iPhone 14.
  • Clearing individual app cache varies by app — some apps let you clear cache in their settings, while others require you to offload and reinstall the app.
  • Offloading an app removes it but keeps your data, then you can reinstall it fresh, which clears all its cache at once.
  • Clearing cache does not delete your photos, messages, contacts, or passwords — only temporary files apps created while running.

Clear Safari cache, history, and cookies

Open Settings, scroll down and tap Safari, then scroll to the bottom and tap Clear History and Website Data. A menu appears asking what time range to clear — tap All time to remove everything, or choose a specific range like Last Hour or Last Day. Tap Clear History and Data to confirm.

This removes Safari's browsing history, cookies, and cached website files. It does not affect other browsers like Chrome or Firefox if you use those instead — you would need to clear cache in each browser separately through their own settings.

Clear cache for individual apps

Most apps do not have a built-in cache-clearing option in their settings. The most reliable way to clear an app's cache is to offload it, which removes the app but keeps your data, then reinstall it fresh.

Go to Settings > General > iPhone Storage. Find the app you want to clear, tap it, then tap Offload App. A warning appears saying your data will be kept — tap Offload to confirm. Once it finishes, tap the app name again and tap Reinstall App. The app downloads fresh and its cache is cleared.

Some apps like Instagram, Gmail, or Spotify do include a cache option in their own settings. Open the app, go to Settings or Account, look for Storage or Cache, and tap Clear Cache if it appears. Check the app's help section if you are unsure whether it has this option.

Free up storage by clearing cache system-wide

If you are running low on storage space, clearing cache across all apps at once is faster than offloading each one individually. Go to Settings > General > iPhone Storage. Scroll down and look for Recommendations — if you see Enable Automatic Offloading, tap it and toggle it on. This tells your iPhone to automatically remove unused apps and reinstall them if you open them again, which keeps cache from building up.

You can also see how much cache each app is using. In iPhone Storage, tap any app and look at the size listed — the larger the number, the more space it is taking up, which usually includes cache. Offloading the largest apps first frees the most space.

When to clear cache and when not to

Clear cache if an app is crashing, loading slowly, or behaving strangely. It is also worth clearing if you are within a few gigabytes of your storage limit. You do not need to clear cache on a schedule — waiting until you have a reason keeps your apps running smoothly without unnecessary work.

Do not clear cache if you rely on offline access. Some apps like maps or reading apps store cache so you can use them without internet. Clearing that cache means you will need a connection the next time you open them. If you are about to travel somewhere without service, skip clearing cache until after you return.

Frequently Asked Questions

Does clearing cache delete my photos or messages?

No. Cache is only temporary files apps create while running. Your photos, messages, contacts, passwords, and all personal data stay on your iPhone. Clearing cache only removes data that apps can rebuild automatically.

Will clearing cache make my iPhone faster?

It may help if an app is frozen or crashing. For normal use, clearing cache makes little difference to speed — your iPhone runs the same whether cache is full or empty. The main benefit is freeing storage space.

How often should I clear cache?

Only when you have a reason — an app is misbehaving, you are low on storage, or you want to remove browsing history. Clearing cache on a schedule is unnecessary and may slightly slow down app loading until cache rebuilds.

Can I clear cache for all apps at once without offloading them?

Not directly. iPhone does not have a single button to clear all app cache. You can offload multiple apps at once by going to Settings > General > iPhone Storage, tapping each app, and choosing Offload App. Reinstall them afterward to clear their cache.

What is the difference between clearing cache and clearing storage?

Cache is temporary files. Storage includes everything — your apps, photos, messages, and cache combined. Clearing cache frees a small amount of space. Clearing storage usually means deleting apps or photos, which frees much more space but removes things you may want to keep.
