It's not often that you will need to clear the cache on your iPhone or iPad, but there does come a time when it's a good idea to clear all that old Safari data and cache. Over time, cache can take up space on your iPhone as part of Safari's website data (and other apps too), and though it isn't often that it takes up a ton of space, if you are struggling with an iPhone storage issue, it's a good idea to give it a go!

Clearing up Safari cache and website data is also a good way to clean up Safari if you've recently had an issue with spammy sites or pop-ups. If you've had a persistent issue with popups or spammy sites, this clearing of Safari website data and cache is a great way to resolve that issue. Plus, clearing your cache is as easy as just a few simple steps.

Keep in mind, clearing cache on an iOS device is not like clearing cache on a computer. You won't be able to go in and delete all the cache on your iPhone or iPad at once. Each app has its own associated cache and app data. When people talk about clearing cache on an iPhone, they are mostly referring to Safari cache and website data, as well as some apps with a cache clearing option (these apps are few and far between), because all the cache and data aren't readily accessible to manage on an iPhone.

This guide will walk you through how to clear your Safari cache and website data in under a minute.

Note: Many apps do not give the option to clear cache. The only way to clear cache would then be to delete the app and it's data. Luckily for you, clearing every app's cache isn't really necessary. Offloading apps is not a viable way to clear cache because it was not meant for this purpose and so not all cache or data gets cleared during this process.

Some apps, though they are few and far between, include a reset or clear cache option. For example, Slack has a "reset cache on next launch" option, so that cache will be reset upon launching the app next.

To clear third-party app cache try the following:

  1. Open the Settings app.
  2. Scroll down toward the bottom of the page and click a third-party app.
  3. See if it has a similar option for clearing cache.
  4. Continue through the list of third-party apps to clear their cache.

Unfortunately, most apps do not have this option. It is rare. You can, if you want, also delete unwanted apps to clear their cache. Only consider deleting apps you do not want since this deletes all app data.
