How to clear cache on iPhone

iPhones generally get slow as they gradually get filled with files and apps that are not wanted. In this article, we will be explaining how to clear cache on iPhone which includes clearing history & website data, blocking cookies, deleting unwanted apps, freeing up space by restarting the iPhone, and clearing your iPhone cache from your Mac or PC. All these should get your iPhone to run faster.

Fundamentally, the cache is your iPhone’s store of memory for particular apps, including the Safari browser (the iPhone default browser) and third-party apps like Facebook, Spotify, TutuApp, and Tinder. Nonetheless, before you start clearing your iPhone cache, note that clearing the cache will erase the data for any application’s cache you clear.

Cached data includes all the files and images that your phone has concealed in its memory. That includes scripts and passwords from previously visited websites that your phone stores for easy access.

An app can clog your ‌iPhone‌’s cache to the point where general performance takes a serious hit. So, it is a good practice to thoroughly clean the cache now and then to make sure your device isn’t unnecessarily slow in processing. A clear-out also helps on a human level as it makes it possible for you to focus on the apps and files you do use. Here’s how you can effectively clear the cache on your iPhone.


How to Clear Cache on iPhone

Clearing the cache in Safari is quite simple. Just make sure follow the steps below;

  • Open Settings, and scroll down to the 5th group of options (starting with ‘Passwords & Accounts’). Tap Safari.
  • Then, scroll down and tap ‘Clear History & Website Data’.
  • A popup will show up, tap ‘Clear History and Data’ to confirm.

To visit websites without leaving any history on your browser, turn on private browsing.

When there’s currently no history or website data to clear, the setting will turn gray. The setting might also be gray if you have already set up website content restrictions under ‘Content & Privacy Restrictions’ in Screen Time.


How to Block cookies on an iPhone

A cookie is a bit of data that a website puts on your device, so it can remember you when you visit the site again. To pick whether Safari blocks cookies, tap on Settings > Safari, then turn on ‘Block All Cookies’.

If you block cookies, some webpages might not work. Here are some examples:

  • You might not be able to sign in to a website using your correct username and password.
  • You might see a message that your browser’s cookies are off or that cookies are required.
  • Some features on a website might not work.

Use content blockers

Content blockers are third-party apps and extensions that allow Safari to block cookies, resources, pop-ups, images, and other content.

Here’s how to get a content blocker:

  • Download a content-blocking application from the App Store.
  • Tap Settings > Safari > Content Blockers, then set up the extensions you want.

Note: You can use more than one content blocker.


How to Delete Unwanted App Data

Another useful method on how to clear cache on iPhone is by deleting app data you don’t want. Other apps store data, and these data can be cleared using the Usage option in Settings.

Tap Settings > General > iPhone Storage.

Under the recommendations for ways to save space, you’ll see your apps in descending order of the amount of storage they take up.

Tap an app that you feel is taking up a lot of unnecessary space. Check the figure for ‘Documents & Data’. This includes related media such as pictures, save games and preferences, songs and podcasts; in some cases, it can be considerably larger than the app itself (like the app in the image below).

If the Documents & Data figure is over 500MB, and you’re ready to lose the files listed above, consider deleting and reinstalling the app to clear this space. (The app above has 2.71GB probably because WhatsApp has a lot of media file such as images, videos, audios, stickers, GIFs, documents, etc)

If you decide to continue, tap on ‘Delete App’, confirm, then go back to the App Store (or your Purchased list) and re-download it. This clean install won’t have all the data and documents and will be smaller.

Freeing up Memory by Restarting Your iPhone

Generally, iOS does a great job managing memory without any user involvement. But restarting an iPhone regularly is a great way to clear out some memory and ensure the most important apps have enough to run happily.

Here’s how to restart your iPhone:

Hold down the power button at the top or top-right of the device until “slide to power off” shows up. If you have an iPhone without a Home button (an XR, 11, 11 Pro, etc.) you’ll be required to hold down both power and volume up until the slider shows up. Then, swipe the power off slider.

Wait until the device has completely powered down, then press and hold the power button to turn on the iPhone again.

Restarting your iPhone regularly used to be an important tip on how to clear cache on iPhone, but it’s less so these days. However, it can still be useful in older models.


Clearing iPhone Cache from Your Mac or PC.

There are a lot of apps out there that perform a fast and efficient job of cleaning out files you don’t need. Generally, these apps are downloaded to your Mac or PC; then you connect your iPhone and let the app do its job.

A cleaner app is usually the most effective way to free up space on your iPhone, but if you want a fully-featured one, they normally cost about £20/$20. Paying that price range for a cleaner is absolutely better than having to cough up for a whole new phone.
