How to Clear App Cache on iPhone?

Apple devices are superior to many competitors in functionality, convenience, and iOS performance. But even the latest model of the iPhone cannot avoid memory problems. Most of the internal storage of iOS devices is occupied by multimedia files. Over time, however, the cache of apps in use gets larger. This reduces the amount of available storage space and degrades app performance. Read this guide to the end and learn how to clear app cache on iPhone.

What is a Cache on iPhone, and Why Do You Need to Clear It Up?

Modern smartphones are characterized by high performance and speed. But over time, the speed of information processing decreases due to the reduction of free memory of the device. The cache is a temporary storage of data used by applications and the system to load pages and data already familiar to the user. It turns out that each previously opened page is stored on the device in the cache memory. And when the user revisits it, the loading is much faster.

What is wrong with opening pages that interest people more quickly? Unfortunately, the more such data is stored in the cache, the slower the smartphone works due to the lack of RAM and storage. Consequently, the bulk of the copies of this information is not used by applications and simply overload the device. So, you need to periodically clear iPhone memory to speed up its work.

How to Clear the App Cache on Your iPhone?

The main memory on any cell phone is occupied by multimedia files and applications that work with images and videos. These include messengers, social networks, video hosting, and navigators.

For example, you need to delete the cache from applications such as Telegram, Facebook Messenger, Twitter, WhatsApp, Instagram, and YouTube on the iPhone.

Unfortunately, iOS does not have a cache cleanup feature for all apps at once. You will need to open each app individually and use the settings to delete data that is not needed.

First, check which apps on your iPhone take up the most memory. Some of them may take up more than 2-3 Gb. Most of that memory is loaded with cache, which you can clear.

Check the space occupied by multimedia apps in a few clicks:

  1. Go to Settings > General.
  2. Open iPhone Storage.
  3. Select the apps with the largest cache capacity (messengers, video hosting, streaming services, and audio services like Spotify) from the list.

Choose iPhone cache cleaner apps that take up more than 300-500 Mb of memory. So they have the most cache. Then open each app and go to the Data menu in the settings.
