How to Clear Documents and Data Cache on iOS devices

Using an iOS device is fun, having apps on your iPhone and iPad is more fun.

Sorry to cut the fun part!

Running out of phone storage is not cool.

We’ve all been there.

Here’s what you may already know: iOS apps take a lot of storage space.

Unless you have an iPhone with a 128 GB+ internal storage, you will be cleaning your storage more often.

There are several files and apps on our iOS device, and in fact, I have a lot of essential media files on my phone.

The cool aspect is that iCloud automatically store media data on any registered iOS device. However, app data is retained locally on our device.

As a result, it is easy to run out of internal storage space, as some apps, especially social media, can cache as minimum as 100 MB.

Hence, it is essential to delete documents and data for each app on your iOS device.

What is Documents and Data on iPhone?

Whenever you install an app and use it for a few days, you may discover that the app is taking up additional space on your phone, apart from the app’s package file size.

Every App needs to be fast and efficient.

Apps end up hosting content, also known as cache, on a local storage device to match the desired level of efficiency,

The benefit of this is to speed up loading time since there is no need to reload content from the server as it is already stored locally.

There is a downside.

Certain apps like Facebook, Twitter, Snapchat and Instagram, that everyone uses frequently take up a considerable amount of space because of :

  • Media files.
  • Login details.
  • Preferences.
  • User data.

Therefore, if you are a user with a low phone internal storage, you won’t fancy apps storing documents and data on your device; there are important files you may need to save instead.
