Sadly, your iPhone’s storage isn’t infinite. You may reach a point where apps won’t install, the camera won’t take a selfie, and songs won’t download. On top of that, your device may begin to lag and slow down significantly because it has no room to carry out everyday tasks. Thankfully there are many ways to free up space, one of them being deleting the cache.

You may be thinking, what really is a cache? A cache is a hardware or software component that stores data so that future requests for that data can be completed faster. The data stored in a cache is usually from an earlier visit to a website or app.

In this blog we take a look at the ways to clear your cache on your iPhone, as well as on third-party apps to enable you to free up space and improve the performance of your device! 


How to clear your cache on your iPhone:

When it comes to freeing up space on your iPhone, clearing your Safari's cache is one of the quickest and easiest things to do. As many people use Safari as their main browser, the cache can become clogged up quickly with data from day-to-day usage. 

To clear your cache follow the steps below: 

  1. Open Settings
  2. Scroll down and tap Safari (listed within the first section of Apple's apps)
  3. Tap Clear History and Website Data
  4. Select Clear History and Data again

While in your Safari settings, you can also ensure that you have removed all your website data, which can sometimes amount to over 1GB. To do this simply:

  1. Select Advanced at the bottom of your Safari settings
  2. Tap Website Data
  3. Select Remove All Website Data


It is important to note that when you are clearing your cache it does remove all of your website data, browsing history and cookies. If you do not want to get rid of these, it may pay to clear the cache in some of your third party apps by following the steps below. 


How to clear your cache on your iPhone's third party apps:

Along with Safari, you can clear cached data for other apps that are installed on your iPhone to free up space. The process for completing this action is similar to that of clearing your Safari's cache. Follow the steps below: 

  1. Open Settings
  2. Scroll down until you find that app that you want to clear
  3. Select it and tap the toggle next to Clear Cache

When going through third party apps, it is important to note that not all will have a cache as not all apps store data from usage. 


What is the importance in clearing your cache? 

Simply put, cache is data stored locally by the operating system and apps. It’s where webpages, game saves, in-app downloads, and more are stored on your phone. It’s also where iOS stores temporary information when writing files or when it needs a scratchpad. All of this data takes up space, which in turn can limit your downloads and the phone’s performance.

Clearing your cache can help protect your information, while also potentially helping your device to run better. Clearing your cache is a method of getting rid of old data, so it can help some applications run better if old data is preventing them from running optimally.


When it comes to controlling your cache, a simple restart of your phone can also help to minimise build up of information increase the performance of your iPhone. Although a restart does not clear all of your cache, it does help to remove temporary information that is being stored on your iPhone that is not essential.
