Steps

  1. Open Settings, tap General, then iPhone Storage. Wait for the list to load so you can see which apps and files take up the most room.

  2. Scroll to Safari and clear its data. Go to Settings, Apps, Safari, then Clear History and Website Data and confirm. This wipes the browser cache and cookies.

  3. For a finer clean, open Settings, Apps, Safari, Advanced, Website Data, then Remove All Website Data. Use this if the main Safari option is greyed out.

  4. Offload apps you rarely use. In Settings, General, iPhone Storage, tap an app, then Offload App. The icon stays on your Home Screen and your documents are kept.

  5. Clear a stubborn app cache by deleting and reinstalling it. Long press the icon, tap Remove App, Delete App, then download it again from the App Store.

  6. Clean up inside chat and social apps. Open each app's own settings and look for storage, cache or media options, then clear downloaded media you no longer need.

  7. Restart the phone to finish. Press and hold the side button with either volume button, slide to power off, wait 30 seconds, then hold the side button until the Apple logo appears.

Tips and common mistakes

Clearing the cache never deletes your photos, contacts or messages, so it is safe to repeat whenever storage fills up.

Clearing Safari data signs you out of websites, so make sure you know your passwords before you tap it.

Offload App is safer than Delete App because it keeps your data and only removes the app itself.

Skip third-party cleaner apps from the App Store, since iOS does not let them reach other apps' caches.

Questions

Does clearing the cache delete my photos?

No. It only removes temporary browser and app files. Your photos, videos, messages and contacts stay exactly where they are.

Why is there no Clear Cache button on my iPhone?

IOS does not have one universal button. You clear Safari data in Settings, and clear other apps from inside each app or by reinstalling it.

Will this fix a lagging iPhone?

It can help if storage is nearly full or Safari has built up a lot of data. If the phone is still slow, check for an iOS update in Settings, General, Software Update.
