Unlike Android, iPhone has no single "Clear cache" button. To clear an app's cache without deleting it, you either offload the app (which clears its cached files but keeps your data), clear cache from inside the app's own settings where one exists, or clear Safari data from Settings. That is the honest answer most guides skip: iOS manages cache automatically and only exposes manual clearing in a few places.
TL;DR
- iOS has no system-wide "clear cache" like Android — do not look for one.
- Offload an app (iPhone Storage > [app] > Offload App) to clear its cached footprint while keeping your data.
- Some apps (Chrome, WhatsApp, Telegram, Spotify) have an in-app Clear cache in their own settings.
- Safari clears via Settings > Apps > Safari > Clear History and Website Data.
- Avoid Clear/Delete App if you want to keep logins and downloads.
Why is there no "clear cache" button on iPhone?
Apple designed iOS to manage caches itself — apps are expected to purge their own temporary files, and the system reclaims space automatically when storage runs low. So there is deliberately no Android-style per-app cache button in Settings. This trips up people switching from Android, who hunt for a button that does not exist and assume something is wrong. Nothing is wrong; the controls are just in different places.
Option 1: Offload the app (the closest thing to "clear cache")
This is the cleanest way to clear an app's cached bulk without losing anything:
- Open Settings > General > iPhone Storage.
- Tap the app (the list is sorted by size).
- Tap Offload App, then confirm.
Offloading removes the app's program files and cached data but keeps your documents and data. Tapping the icon afterwards reinstalls it and restores your state. Check the app's "Documents & Data" line first — if that is what is large, offloading is the move.
Option 2: Clear cache inside the app
Several heavy apps expose their own cache control:
- Chrome: menu > Settings > Privacy > Clear Browsing Data.
- WhatsApp / Telegram: Settings > Storage and Data > Manage/Storage Usage.
- Spotify: Settings > Storage > Clear cache.
These clear cached media without signing you out — the safest option when an app supports it.
Option 3: Clear Safari
Settings > Apps > Safari > Clear History and Website Data. Note this also clears history and signs you out of sites. To clear cached site data without wiping history, use Safari > Advanced > Website Data and remove individual sites.
What iOS does natively, and where it stops
iOS purges caches on its own and offers Offload — that covers most cases. What it will not do is let you clear one app's cache from a single screen, or tell you which app's cache is the bloated one. You have to read the storage list and decide. A cleaner cannot add an iOS cache button either, but it tackles the bigger space drains caches distract from: large videos, duplicates, and screenshots.
What this cannot do
There is no way to bulk-clear every app's cache at once on iPhone, and offloading will not help an app whose bulk is genuine downloads rather than cache. For those, delete the downloads inside the app. A full Delete App is the only way to wipe everything an app stored — use it only when you are fine losing local data.
FAQ
How do I clear app cache on iPhone if there is no button?
Offload the app (Settings > General > iPhone Storage > [app] > Offload App) to clear cached files while keeping your data, or use the app's own in-app "clear cache" if it has one.
Does offloading an app clear its cache?
Yes — offloading removes the app's program files and cached data while keeping your documents and settings, so it is the closest thing iOS has to "clear cache."
Why does iPhone not have a clear cache button like Android?
Apple designed iOS to manage caches automatically and reclaim space when needed, so it never added a per-app cache button. The controls live in Offload and individual app settings instead.
Will clearing cache delete my photos or logins?
No. Offloading and in-app cache clearing keep your photos and logins. Only Delete App (or Safari's Clear History) removes data or signs you out.
