What does it mean to clear the cache on Android

What does it mean to clear the cache on your Android phone?

A tap on the program from the list opens a properties window with two options: Clear Cache. With this function you delete all the cache files of the app. Your logins and passwords, as well as saved games and other similar information, will remain intact.

In older versions of Android you can delete all cached files at once by selecting “Settings”. “Storage”. “Cache data”. Next, just click OK if you want to delete unnecessary files.

What are cache files on Android?

Cache files are temporary storage files that store information on your device to perform a task quickly the next time. In Android, cache files are created by apps and web browsers. When you open a web page on your device, it saves its data as cache, so the next time you reload the same page, it takes less time to open it. It’s the same with Android apps, as your phone memory stores data for different apps.

But cache files can increase in number and then contribute to the problem of full storage on your phone. Sometimes system errors can also occur due to old or corrupted cache files. To avoid them, you need to learn how to delete the cache on Android. In this blog, we discuss simple ways to clear Android cache using manual and automatic methods.

Ways to clear the cache

There are several ways to clear cached files. The Android operating system has a simple tool for deleting old data. In addition, there are special optimizer applications in GooglePlay. They improve your phone’s performance and clean up system junk.

Let’s take a closer look at all the cache clearing methods.

Tip. Before deleting files, be sure to close all running apps, except for cleaning apps or phone settings.

Android settings

You can clear the cache on Android using standard tools. To do this, you need:

  • Call up the settings menu;
  • Scroll through the list, find “Storage”, click on it;
  • Swipe down to the item “Cache data”;
  • Click on it, a window suggesting to clear the cache appears;
  • Confirm the operation, wait for the system to delete all files.

In the storage you can see the information about how much memory is occupied and free. If there is enough free RAM, it is better not to clean the cache.

On Samsung Galaxy phones you can clear the cache by going to “Settings” “Device Maintenance” “Memory” and pressing the “Optimize” button.

Clean Master

This is a special application to increase your phone performance, remove old and unnecessary files, clean the cache. To clear the cache:

  • Download Clean Master from the link below, install it on your phone;
  • Launch the application, go to the “Trash” section;
  • Clean Master will automatically analyze and display all unnecessary things that prevent the stable operation of the phone;
  • Tick the “System cache” box and confirm the removal.

Clean Master. Free app, but there is additional paid and promotional content. The application has additional features, such as putting inactive applications to sleep. This option allows you to free up some memory for productive work on your smartphone.

Piriform CCleaner

CCleaner was originally a memory cleaning program for computers, laptops. The developers created a mobile version to work with Android. Cached files are cleaned similarly to Clean Master:

  • Download and run the app.
  • On the first run, click on “Analyze”; the analysis of the device memory will start.
  • Select “Hidden cache” and “Visible cache” from the menu.
  • Click the “Complete Cleanup” button.
  • Wait until the program erases the cache.

CCleaner has paid features (one-year subscription costs 12.49), but you can also use the free. Basic. version.

App Cache Cleaner

It works similarly to previous applications, but has several differences. App Cache Cleaner cleans your phone at the set time, according to the schedule. You can also set up to transfer cached files to removable media, like an SD card.

Important: Cleaning the cache can not only speed up applications, but also slow down the operating system. Don’t clean the cache too often: your smartphone will perform operations more slowly and behave unpredictably.

What is a cache?

The term comes from the French word for “hiding place”.

In simple terms, the cache is a copy of files and data that are stored in the memory of your phone, computer, browser, or server.

When a user first visits a website or launches a mobile app, it logs and stores data (images, files, and other media). this process is called cache data.

When you visit a familiar site or run an application again, your device loads and processes data much faster thanks to the cache. This is because the website or application does not need to download the same files again.

How to clear the cache and data on Android

It is not possible to give exact instructions for each smartphone, because it depends on the manufacturer and OS version, but the general rules are as follows.

Launch “Settings” and go to “Storage” (or search for it). This way you can find out how much of your smartphone’s memory is occupied and by what.

Under “Storage,” find “Apps” (or “Other apps”) and select it. It will list all the applications and how much space each takes up. In some versions of the OS you can find a sorting of applications alphabetically or by size.

Go inside the app and delete the cache or data. You just need to understand that this action is irreversible.

Regarding special applications for cleaning, I am very categorical and do not recommend their use. Despite their promises of speeding up the system almost tenfold, at best they will just do the same thing I just described. So why not do it yourself without installing questionable apps that will also collect your data? The only optimizer application that I trust is Google Files, but it works with the storage and cleans debris in the first place. Although, you can’t blindly rely on it either, but it’s made by Google, and there’s a lot more trust in it than in some left-wing developers.

If you still want to install an app like this, just be aware of the fact that they run in the background and use system resources. Even if they speed something up, they will immediately slow it back down.

How the cache works

The application cache memory in the Android phone is relatively small compared to the amount of memory in a smartphone or tablet.

Its purpose is to reduce the access time for data processing and minimize the load on RAM to make it available to other devices. It bridges the gap between performance growth and the speed of access to storage media.

Using the memory cache has two advantages: shorter access times and more efficient use with a built-in intelligent data storage algorithm.

The memory controller detects the sequence of frequently repeated operations and in the process of execution it intercepts them and replaces the data from the cache.

Thus, the processor saves a long access path to the main memory. The cycle in the cache is executed many times faster than if it is taken from the main memory.

Where is the cache memory on Android?

On your own, the cache can be found in the following locations: In the root of the phone memory or SD card folder with the name of the application In the /Android/data folder. In the /Android/obb folder.

After clearing the cache and deleting cookies: Some site settings, like saved usernames and passwords, will be deleted. If Chrome sync is enabled, you won’t automatically sign out of the Google account with which you sync. This will delete the data on all of your devices.

What is the cache on your phone and what does it mean to clear the cache

In IT sphere, cache is used almost everywhere, because it is an intermediate clipboard where the frequently requested data is stored. It allows for fast access, so different programs are quickly downloaded and get the information. In simple words cache is storage of information for frequent use. It is downloaded to the RAM of the device. The main drawback is the limited volume and need for periodic cleaning.

If we simplify the concept of cache for Android smartphones, we can say that the base stores data about the downloaded programs. For example, after logging into the application and viewing a photo, each picture is cached. It’s necessary for fast loading of images at the further opening. The same action is carried out for the other command, the smartphone saves everything and recreates instantly on request.

When programs are launched from the gadget, it records the most frequent and popular requests, including passwords, logins, etc.д. It allows you to quickly access your personal social networking profiles or other programs without having to constantly enter data. However, all the files in the memory of the device is easy to delete, which is difficult to say about the cache memory. Storage is carried out in separate folders, so many users are not even aware of the existence of such a system. Over time, memory fills up, decreases, there are large amounts of unnecessary data in the smartphone.

Why data caching is needed

The main problem with the cache is that the Android phone is constantly clogged with various information, so the memory of the device decreases, slowing down the gadget. As a result users run out of megabytes for installed and system applications to function. Due to this, the cache begins to do the exact opposite function, not the one for which it was created (there is a slowdown, not acceleration of performance).

In such cases, you just need to do a clean-up of the Android system and delete unnecessary, accumulated files. The procedure is very simple if you know some specifics and can be carried out by different methods.

Cleaning the cache is a safe procedure if you follow the instructions, but the acceleration of functions and the appearance of free memory will be significant and noticeable for users.

What are the types of cache

Before the procedure of clearing Android with clogged cache, it is necessary to understand the main types of smartphone memory. The creators of the technique use 3 types:

  • Dalvic cache. the information which is formed by the Dalvic machine. This type of memory allows you to save complete information that is required for the rapid implementation of commands in applications, they are presented as optimized documents. The information is stored in closed folders that are difficult for a normal user to access.
  • System cache. is necessary to cover all the information that is needed for the system programs integrated into the Android operating system. In other words, this type is the software memory of the installed applications, which will be immediately after the first turning on the gadget and configuring it after the purchase. Popular algorithms that the user sets, remain in a separate folder to accelerate performance.
  • Application memory. the cache for third-party programs that users download and install on Android. In addition, this category includes pictures, games, etc.д.

All the described kinds can occupy a lot of free memory in the device, so you can clean it manually, by third-party applications and other methods described below.

When is it worth clearing the cache

For some users it may seem strange procedure of clearing, because the information in the storage helps to quickly enter the different programs. However, there is an important drawback. the accumulation of unnecessary data, which is constantly increasing. When using a new device with few programs the slowdown and deterioration of performance is unnoticeable. After a few months of active use, a significant “braking” of the Android system begins. As a result of the large number of saved music, photos and videos, as well as data from the cache memory there may simply be no space for storing or recording new funds.

It is best to perform the clearing procedure once or twice a month. This will not only remove unnecessary information from the phone, but also help eliminate system errors. If apps don’t launch, shut down during operation, or other defects appear, then you need to start cleaning.

By clearing the cache of the application in Android, there is a possibility of their failure at login and further functioning. It is recommended to close all active programs before taking action.

If you clear the cache on your phone, what will be deleted?

After deleting the cache you should not worry, because the process does not involve the complete clearing of programs or personal data from the phone. The operation is not harmful, but all saved information to run applications is invalidated. In this case, you need to prepare for the procedure in advance to exclude malfunctions. For this you will need to close all running programs, save the necessary materials from them and rewrite the logins with passwords for authorization.

How to clear the cache on Android

Deleting unnecessary data and speeding up Android performance is done by several methods. The manual mode is suitable for this, when using the built-in utilities, as well as the installation of third-party applications to accelerate the operation. You can see the information on

Built-in methods

Manual method of clearing mobile device memory implies using the built-in utility. The process is performed both for a single application and for all installed in the gadget. The second method is considered more radical, but with noticeable results. To perform the tasks, you need to follow the following instructions:

  • On the device, go to the settings menu via the main menu or the notification bar at the top, dragging your finger down.
  • In the section “Devices” there is a line that indicates the memory of the gadget, you need to click on it to open.
  • Find “Cache data” and run the menu. The smartphone will display a form-request to confirm the operation to delete the accumulated data.
  • You need to select “OK” to execute.
