How to Clear the Cache on Your iPhone: Step-by-Step Guide

As we use our iPhones to browse through various websites and use internet-based apps, we tend to generate data called ‘cache’ which is stored directly into the internal memory. Although this data helps in reducing the tasks of loading the apps’ or websites’ resources from scratch, it can sometimes act as a bottleneck to your storage, especially on iPhones with storage capacity as low as 64GB. That said, to prevent running into any performance issues, you can easily get rid of the cached data on iPhone and enjoy more storage space for apps and media files.

In this blog post, we’ll explore how to clear the cache on your iPhone with a step-by-step guide. We’ll also look at the benefits of clearing cache on your iPhone and provide some tips for maintaining optimal performance.

Explanation of what cache is and why it needs to be cleared

A cache is the storing of website and app data such as files and media on your local storage. This is done in order to prevent the program from searching or rendering the resources from scratch which can be otherwise time-consuming and increase the wait times for the user. But at times, the cache can act as a burden on low-storage devices after a while and may give performance issues. This is why you may want to get rid of the cache on your iPhone for smooth and quick operations.

Overview of benefits of clearing cache on iPhone

Clearing the cache on your iPhone can help improve the overall performance by freeing up storage space, reducing the load on the device’s processor, and speeding up app launches. In addition, clearing the cache can help you troubleshoot app errors and fix any glitches that might affect your device’s performance.

Step-by-Step Guide

There are different ways to clear the cache on your iPhone, depending on whether you want to clear the browser cache or the app cache. Here’s a step-by-step guide:

Step 1: Open Settings App

To start, open the ‘Settings’ app on your iPhone. This can be done by tapping the ‘Settings’ icon on your home screen.

Step 2: Scroll down and select Safari

If you want to clear the browser cache, scroll down until you find ‘Safari’ and tap on it. If you want to clear the app cache, scroll down and select the app you want to clear the cache of.

Step 3: Clear Safari Cache

If you selected Safari, scroll down until you find the ‘Privacy & Security’ section and select ‘Clear History and Website Data.’ Confirm the deletion by clicking ‘Clear History and Data.’

Step 4: Clear App Cache

If you selected an app, scroll down until you find the toggle named ‘Clear temp data on next start.’ Toggle it on to clear the app cache without deleting the app.

Step 5: Restart the iPhone

Once you’ve cleared the cache, restart your iPhone to ensure that the changes take effect.

Tips for Maintaining Optimal Performance

Now that you know how to clear the cache on your iPhone, here are some additional tips to help you maintain optimal performance:

Regularly Clear Cache

Clearing the cache on your iPhone should be a regular part of your device maintenance routine. It’s a quick and easy way to free up storage space and improve your device’s speed and overall performance.

Limit App Usage

The more apps you have on your iPhone, the more storage space they take up, which can slow down your device. Try to limit the number of apps you have installed and delete any apps that you no longer use.

Disable Background App Refresh

Background app refresh is a feature that allows apps to refresh their content in the background while you’re not using them. While this can be useful, it can also slow down your device and drain its battery. Consider disabling background app refresh for apps that you don’t use often.


Clearing the cache on your iPhone is an important step in maintaining optimal performance and freeing up storage space. By following the step-by-step guide we’ve provided in this blogpost, you can quickly and easily clear both your browser cache and app cache. Additionally, implementing the tips we’ve shared for maintaining optimal performance will help ensure that your iPhone continues to run smoothly and efficiently.

Remember that regularly clearing your cache, limiting app usage, and disabling background app refresh can all contribute to a better overall experience with your iPhone. So, don’t hesitate to take these steps whenever you notice a decrease in your device’s performance or when you simply want to free up some storage space for new apps and media files.
