What you need

Steps

  1. Open Settings, tap General, then tap iPhone Storage. Wait a few seconds for the coloured bar and the app list to load.

  2. Scroll the app list, which is sorted by size. Apps with large caches, like Safari, social apps and Messages, usually sit near the top.

  3. Tap an app to see how its space splits between the app itself and its Documents and Data. That Documents and Data figure is the cache.

  4. To actually clear an app's cache, delete the app and install it again from the App Store. Sign back in and the cached junk is gone.

  5. Use Offload App instead if you only want quick space. It keeps your data, so it frees room but does not clear the cache.

  6. For Safari, go to Settings, tap Apps, then Safari, then Clear History and Website Data and confirm.

  7. For single sites, open Settings, Apps, Safari, Advanced, Website Data, then swipe left on any large entry and tap Delete.

  8. Restart the phone by holding the side button and a volume button, then sliding to power off. Turn it back on and recheck iPhone Storage.

Tips and common mistakes

You cannot clear System Data directly. It usually shrinks after a restart or an iOS update.

Deleting an app wipes any unsaved work inside it, so back up important files first.

Caches rebuild over time, so repeat this check every month or two.

Clear website data only for sites you do not mind logging into again.

Questions

Where is the clear cache button on iPhone?

IOS has no single clear cache button. You clear app caches by deleting and reinstalling the app, and clear Safari's cache in Settings under Apps, then Safari.

Will deleting an app remove my photos and messages?

No, photos and messages live in separate apps and stay put. You only lose data saved inside that one app, and signing back in usually restores cloud-backed content.

Does clearing the cache break anything?

No. The app simply downloads fresh files the next time you use it, which can use a little data on the first launch.
