What is Cache and How to Clear Cache on Android

All those users who own an Android phone have experienced eventually a decrease in the performance of their device, most without knowing the cause. This may well be due to problems in the hardware of the phone; the fact is that it is most likely that this problem is directly related to the cache of Android.

The cache of the Android operating system is one of the most important parts of it since important functions are carried out in this space, and if it is not in good condition, it has a direct impact on the smartphone.

If you want to know what the cache is and how to prevent it from becoming a problem, we recommend reading this article, where you will find a lot of information about this important topic.

What Is the Android Cache?

Basically, the cache memory of a processor is a type of memory similar to RAM, i.e. a memory of the volatile type that empties when we shut down the computer. The fundamental difference of cache memory with respect to RAM is that the former is much faster.

The specific function of the cache memory is to store the instructions and data that the processor needs to access continuously. That is to say, that the cache of Android serves so that the processor can access the data you need for the applications and the operating system in a much faster and more effective way, thereby achieving a much more fluid performance for the entire system.

It should be noted that the word cache is a term of French origin that means “hiding.”

Cached Data

Most users fall into the trap of thinking that deleting cached data and deleting data from applications is the same thing. However, they are two completely different issues and offer different results. If we want our cell phone or tablet to work efficiently, we must first know the main differences between clearing the cache and clearing data from the apps.

As we mentioned, Android cache is a space used to store data temporarily so that the processor can access them more effectively and therefore faster.

If we notice that the cell phone or tablet starts to slow down, or has problems with some processes like video viewing or web browsing, we may need to clear the cache. However, this is not a process that should be done every day, as we will explain later in this article.

It is only necessary to erase the cached data when the applications do not work properly or we need that extra memory to run that heavy app.

On the other hand, deleting the data of an application is a process with a completely different objective, which is really very useful in situations like the inability to start or log off a service, or the app does not boot.

By deleting the application data, all the data that it has generated will be deleted, including all files, databases and account data, among others. That is, the application will return to a state similar to the one it would have if we had installed it recently, without storing any data from its previous use.

To delete the data of the applications, all we have to do is access “Settings”, then “Applications”, where we click on the application from which we want to delete the data. To finish, click on the button “Clear data”.

Simply put, the main difference between clearing an app’s data and clearing the cache is that the first option will permanently erase the data of the chosen app, while the second option will help us to optimize our device by gaining some more performance.

Is It Good To Delete The Cache?

While the latest versions of Android have optimized the consumption and use of resources to obtain at all times the maximum performance of the hardware of the device, the fact is that users still continue to maintain some customs that make us feel that we have control of How our device behaves.

In this sense, one of the most ingrained habits among Android users is to delete the cache on a regular basis, in fact, there are many people who delete it too frequently.

Deleting the cache on a regular basis is not as good a idea as it might seem, since the data stored in the cache is necessary to run the computer properly, and it depends on all the services and applications we are using when the Cell, so if we remove the cache, we will be forcing the system to restart all services, with the loss of performance and resources that this means.

However, this is not the only problem we will have if we remove the cache periodically since most applications store vital data for its operation in this space. By frequently deleting the data stored in the cache, the application must download or generate the data again to work correctly.

We mentioned above that in the latest versions of Android the system’s cache memory has improved, so most of the time it is not necessary or even thinks about it. However, there may be scenarios where it is necessary to delete the device cache. In these cases, it is best to do it by hand that is application by application without installing any app that performs this process automatically.

If you want to know how to clear the Android cache this way, continue reading until the end of the article.

How to Delete the Cache?

While there are applications developed to erase the Android cache, the best way to do this is to take control ourselves. Starting with Android 4.2, the developers have included a system that allows us to do so without having to download any app.

If we want to remove the cache of Android with a single step, the only thing we have to do is a scroll to the item “Settings”, then click on “Storage” and finally press on “Cached data” confirm the order and the System will start with the task.

In case you want to delete only the cache of a specific application, we can do it easily by scrolling to the “Settings” section, then clicking on “Applications”, click on the desired application.

To end the process, press the “Clear Cache” button, after which the system will delete the relevant files.
