What is the cache on the phone (cached data)?

If a free space runs out on a smartphone or tablet, the first thing the user is advised to remove is the cache from memory. And what, in fact, is a cache on the phone or cached data? Let’s figure this out together

A cache is an intermediate quick-access buffer containing information that may be requested. At the same time, access to the cache is much faster than fetching the necessary data from memory or a remote source. However, keep in mind that cache size is limited..

If you do not understand anything from the above, we will try to explain it in a visual way. When you install the application on your Android device, a folder is created to store user settings, various images, logs, etc. Of course, the data in the cache in this case takes up space.

Another example. Let’s say you open VKontakte on your phone and look at the photos. These photos are saved on your device (i.e. cached). What for? And then, if the next time you turn to the same pictures, they will load much faster than without using the cache. The same applies not only to photographs, but also to music and even videos – they are all stored on the device and can take up a lot of space.

The question is, will you again access the watched video? Maybe not, but because the movie is not necessary to cache.

What happens if you clear the cache?

We can say that nothing will happen if we talk about most applications, because you just delete the settings and data that is stored in the cache. That is, in this case, you will not even be deauthorized if you delete the cached data for the same VKontakte application.

You can delete the cache manually, or you can use the applications. We recommend using the first option, since it does not involve the installation of third-party applications. At the same time, some firmware by default use proprietary utilities, which also delete the cache.

For example, consider a Samsung smartphone and One UI firmware. Go to settings.

Find and open the “Applications” section.

Tap on the desired application.

Click on the line “Memory”.

Click “Clear Cache” (do not confuse with the “Clear Data” button – this is important).

The cache has been cleared.

Another example is based on Huawei. We show how to remove unnecessary cache for all applications. In the settings, open the “Memory” section.

Select “Clear Memory”.

Wait for the data to be collected and you will see the “Clear” button under the cache information. You can simply click on it to clear the cache of all applications.

Or select clear cache for specific applications.

As you can see, this is all done very simply..
