It doesn’t take long for caches to fill up on iPhone and iPad. You can clear cache on the browser using Safari or by the third party app. While clearing the cache in Safari is quick and easy with one fell swoop, doing so can be different depending on the third-party app
- Open Settings.
- Swipe down and tap Safari.
- Swipe down again and tap Clear History and Website Data, tap it once again to confirm.
Clearing the cache of third-party apps varies from developer to developer.
For apps that don’t provide a clear cache button, deleting the app and reinstalling it is the next option.
You can always take a look at Settings → General → iPhone Storage to prioritize which third-party apps you may want to tackle first.
