What does it mean to clear the cache on the phone memory. Cached data - what is it? What is cached app data on the phone? What does "cached data" mean in a general sense

The cost of older smartphones is too high. We all understand that the price difference between 16 GB and 32+ GB models is unreasonably large. We are talking about the iPhone, and the whole variety of flagship representatives of Android. As a result, a person takes a younger model with 16 gigabytes of storage on board in the hope that this is enough. But, often the reality does not live up to his expectations.

What eats up memory in a smartphone

First you need to understand that the amount of memory indicated by the manufacturer in the device is not the same as the amount of memory available to the user. That is, in practice, we always have less memory available than what is written on the packaging, and this is true for both the iPhone and the Android family.

In both cases operating system device occupies 2-3 GB of memory, and it is impossible to return them to the user's disposal - this space is needed for the device to work.

So when you're looking for a new smartphone, consider this: 16 GB is actually about 13 GB, and 32 GB is 29-30 GB at best.

In the future, the amount of memory remaining for the user will be encroached installed applications and games. The screens are getting better, the picture should be getting better, the graphics are getting cooler - this seriously makes applications heavier.

In addition, over time, installed applications will get fat, accumulating in memory cache data- this is everything that remains in the device while the application is running and after it is closed. Any application that receives content from the Web stores it on the device for faster delivery to the user. Watch YouTube - get cached videos. Listen to music online - it is cached locally. Surf the Internet through Chrome - pages visited in the browser are cached.

If you have Android and you find yourself in a situation where you urgently need to get several hundred megabytes of space for a video or photo, then clear the cache data.

Settings -> Memory -> tap on Cache data.

You can also selectively clear the cache for individual applications.

Settings -> Applications -> tap on a thick app -> Clear cache.

There are no such regular tools in iOS, but there are third-party utilities.

These days, 1 GB for a single game already seems quite acceptable. Periodic cleaning games with a preliminary question to yourself “Will I still play this?” will help get rid of annoying and unnecessary toys that continue to take up a decent amount of memory. The same is true for any other application. Didn't like the app? Do you plan to use it in the future? Delete it, don't just keep it on your device.

Music uploaded by the user to the device is getting better and better. Some people no longer accept 320 kbps mp3 and want only flac. Such tracks take up several times more space on the device.

Consider whether the headphones you use will provide enough sound quality to make you feel the difference? Maybe an average quality mp3 will suffice?

If it's about Photo and video, it's even worse. The top current smartphones are equipped with 8+ megapixel cameras that can shoot FullHD video with a high frame rate and take very high resolution photos. These photos and videos take up a lot of space. For example, 1 hour of 1080p video can take up 10 GB of space on your smartphone.

With the video footage, there are virtually no options. They need to be periodically moved from a mobile device to a computer for subsequent storage or placement on video hosting.

With the storage of photos, the Dropbox mobile application can help - it has a function to automatically transfer pictures from the device's memory to the cloud.

And yet, the more technologically advanced our mobile devices become, the more space will be required for applications and content. Manufacturers understand this, and often meet the needs of the user by building a slot for smartphones and tablets. removable memory cards. Unfortunately, users of the iPhone, Google phones and some other Android lines are deprived of such an advantage. Google suggests that we store all data on the Web.

This concept is supported by many developers - now we have hundreds of thematic online services that provide content in the form of streaming. They are complemented by dozens of cloud storages. In this case, the device's memory will be clogged much less, but the requirements for the quality and speed of the mobile Internet will increase significantly.

Few people wonder how you can clear the cache on Android. It is understandable, because holding a brand new smartphone in your hands is a pleasure. Everything works quickly, the interface “slips” and almost never crashes, and applications, if they freeze, only in very rare cases. However, several months (and sometimes even weeks) pass, and our device begins to “stumble”, seemingly out of the blue – programs take longer to come off, animations lose their former smoothness, and space on the internal storage begins to mysteriously disappear.

There can be many reasons for this phenomenon, but the first thing you can do to speed up your Android device is to clear it of unnecessary files that accumulate during the life of applications: these can be error data, outdated files, photo thumbnails, browser cache or VK, cookies and a lot of other ballast that spoils our impression of working with the gadget. Such “garbage” files are denoted by the term “cache” (from the English “cache” - cache), and the procedure for deleting them, respectively, by clearing the cache.

70% of residual files are not needed by either the user or the device, and only negatively affect the operation of the smartphone, increasing the time for opening applications and loading the system. They can be safely removed and not be afraid of the consequences.

However, the cache can also store important data, such as audio recordings, photos, or passwords that you have saved. Therefore, you need to approach the procedure for clearing memory wisely. You should learn to distinguish between those files that may later be useful for the normal functioning of the device, and those that can be safely cleared without fear of losing important information.

Types of cache

The Android operating system can cache three different kinds of files:

• The first type of cache is non-system. These are files created by user applications downloaded from the Play Store or other sources. If a lot of programs are installed on the device, such a cache can reach gigantic sizes and then you definitely cannot do without cleaning;
• The second type of residual files are system files. As a rule, they can be removed without a twinge of conscience. The Android operating system will still not let us erase what is needed for its normal operation;
• and, finally, the third type of cache - dalvik. Generated by the system so that the most frequently used programs start faster. We will not go into the intricacies of how this environment works. Moreover, cleaning dalvik-cache is not available to an ordinary user, as it requires obtaining root rights and installing custom recovery.

Basic cleaning methods

Having figured out why we actually need to clear the cache of the smartphone, let's go directly to the procedure. In most cases, you can clean junk files without resorting to installing additional software. The developers of modern Android shells, which are supplied, for example, with devices from Samsung Galaxy, Asus or Lenovo, embed applications in their products that allow them to approach device optimization in the most comprehensive way.

There are more advanced ways to clear the cache, which may be needed, say, if the device does not turn on or goes into an eternal reboot. Let's look at each method separately and determine which files can be changed, and which are best left as is.

Cleaning through settings

You can get rid of all the files that have accumulated on the device right now by simply going to the settings menu and pressing three buttons in turn.

We do the following:

1. On the desktop or in the notification shade, we find the settings gear and go to the "Storage" (or "Memory" - the names may vary depending on the firmware or device manufacturer).

1. Click on the "Clear Cache" line. Without hesitation, we confirm the procedure and rejoice at the release of an additional 1-2 GB of the device's memory, which is so precious in our time.

Everything! The phone was safely cleared and it did not take us even 2 minutes. This is easy to do, but this method does not imply differentiation of deleted files - Android will delete what it sees fit, and we can only hope that, for example, our precious music from VKontakte, which we have been caching for so long and stubbornly. But, if you have nothing to lose, you can try.

How to clean only one application

It happens that the gadget as a whole works flawlessly, but one or more applications are constantly weird: for example, Odnoklassniki crashes when you try to send a message or the game crashes at a certain level - the situation is common and very prosaic.

In order to fix it, it is not necessary to reinstall the application - just clear its cache. Yes, passwords and login may have to be re-entered, but there is nothing to worry about. Indeed, as a result, we will get a fresh and adequately behaving application.

So, to clear the cache of any application (let's take Instagram as an example), we need to:

1. Go to settings and select "Application storage" or "All applications" - the names, again, may vary depending on the version of "Android".

1. Find the program spoiling our blood in the list and click on it. In some versions of the Android OS, applications are divided into groups: "system" and "user". This somewhat simplifies the search if a lot of software is installed on the device.

1. We are interested in the item "Data cleaning". Click on it and agree to the removal. The memory will be cleared for only a few seconds, then we go to check the operation of the program. Most likely, she will no longer bring you past troubles.

Clearing the cache using third-party programs

The methods considered earlier were undoubtedly effective - you can be sure of this if you follow our instructions step by step. However, you can’t call them too convenient - manually climbing into the settings, scrolling through the menu items, and even risk losing important data is not the most pleasant and fast occupation. It is much more convenient to keep a full-fledged application for clearing the cache on your smartphone, which will allow you to quickly and easily delete only what you do not need.

In this article, we would like to demonstrate the operation of two such programs - according to our modest author's assessment, they are the most convenient for novice users and, at the same time, the most functional. These are Clean Master and App Cache Cleaner applications. Let's take a look at each one individually and use screenshots to demonstrate how they work.

Clean Master App

A very convenient utility, which has already been appreciated by millions of users - it is, by the way, that works by default on Xiaomi phones.

To evaluate the capabilities of this program on our own and understand how you can clear the cache with it, we need to:

1. Find and download the application through the Play Market.

1. Open it and view the list of functions that the application provides - it is displayed on the main page. Perhaps, in addition to clearing the cache, you will need something else from this list.

1. We press the "Trash" button, decorated with a trash can icon, and the application starts calculating how much data from all that is stored on our device can be safely deleted (these will be various system reports, cookies, photo thumbnails and other rubbish).

1. Press the "Clear trash" button and enjoy the spectacular animation that accompanies this process. Ready!

App Cache Cleaner

Another, in our opinion, an interesting program for clearing the cache on Android. Its functions are very similar to those that we considered earlier, but there are still small differences - mainly in the interface.

In addition, the utility can transfer applications from internal memory to an SD card. A very useful feature if the storage size of your device does not indulge in its size - this functionality is not implemented in Clean Master. So, in order:

1. To get started, download the application from the Play Market in the same way. Then we open it by tapping on the icon on the desktop and get acquainted with the functions.

1. We are interested in "Quick Cleanup" - we click on the trash can icon and we meet something similar to what we saw in the previous example.

1. Everything is exactly the same: if the file you need is included in the list of files to be deleted, then simply uncheck it and the program will not touch it. Ready!

Factory Reset (Hard Reset)

If you have already tried all the methods, and the phone still slows down or works very badly, we can advise you to reset all data. The method, of course, is radical, but invariably effective - the phone becomes like new and again pleases us with the speed of work. All the problems that you carelessly accumulated over the course of several months of using the device will no longer bother you.

There are two ways to "undress" the phone to its original settings:

• through the "Settings" application;
• through the recovery menu (or "recovery").

These methods are implemented differently on devices from different manufacturers. Information on how to enter the recovery menu on your smartphone can be found in.

In order to roll back the device to the factory state by the operating system, do the following:

1. We go into the settings and look for the option "Backup and reset". On smartphones running MIUI 9, this item is located in the "System and device" section in the list of advanced settings.

1. We press "Clear data" and wait a few minutes, as a result of which all files from our device will be completely deleted - we hope that we should not remind you once again of the need for backup.

1. Ready! Meet the new machine!

Conclusion

Applications installed on our device permanently store residual files of their vital activity on it. Most of them we do not need and they can be safely removed - this will facilitate the operation of the device, free up memory and slightly speed up the device. Clearing the cache is the first thing to do in order to restore the normal operation of the mobile phone. You can do this through the settings or through third-party applications. If the performance situation is completely deplorable, you can resort to resetting to factory settings.

What does it mean to clear the cache: why clear it + 3 ways to clear the computer + clearing the cache of 4 types of browsers + 2 ways to clear the memory on Android + 3 ways to clear the iPhone.

Computers, tablets, phones need competent operation and technical support if you want their work to be correct, fast and uninterrupted.

One of the most important manipulations for keeping the PC “in shape” is the decision to clear the cache.

Let's consider, what does it mean to clear the cache, and how to do it on different browsers and operating systems.

What is a cache?

Cache is a super-rapid memory (buffer) for temporary data with high access speed and limited capacity.

It is needed to speed up access to data that is used frequently. Caching is used by the PC CPU, hard drives, browsers.

Browser cache– storage of temporary data loaded from network resources. The Internet browser saves temporary documents on the hard drive of the PC.

When pages from the Internet are viewed in the browser, it automatically saves some parts of the page to the computer’s memory in order to take the data not from the site server, but from the system’s memory when viewing the page again, which significantly increases the speed of opening the page.

The operation of the caching process is easy to check.
Open any new browser site, then close it.
When you open it again, the site will load much faster than the first time.

The Internet browser does not cache all files and data. It depends on the settings of each site that the webmaster sets.

What does it mean to clear the cache?

The cleaning process involves deleting temporary files saved while working with data, sites. What does "clear the cache" mean? Erase all graphic and text files.

In the next session of the browser, it will again take information from the site server, and again will save the received data to the system memory.

Why clear the cache?

Since temporary documents are stored on the computer's hard drive, over time they take up extra space, which affects the speed of the operating system.

This affects both the operation of the computer itself and the operation of the browser.

If several browsers are used, each of them saves data to the system memory, so the information is duplicated.
Accordingly, it takes up more space.

There is another reason why you need to clean the memory: by pulling data from the hard drive, and not from the server, the Internet browser may not show updates that have occurred on the site.

How to clear the cache on the computer?

Cleaning unnecessary computer files cannot be called a simple procedure, unlike similar cleaning of the browser.

But if your PC has begun to freeze, it is highly likely that such a cleaning will help restore its performance.

Consider the process of deleting temporary documents for the most popular operating system - Windows.

When cleaning, you can use built-in tools or special programs. Standard cleaning with Windows tools is considered more effective, but requires more time and skills.

The standard Windows cleaning consists of 3 items:

• clear cached DNS memory (a system for obtaining information about domains);
• deleting cached files from thumbnails (folder with thumbnails of viewed images);
• clear the cache.

a) Clear DNS cache

Clearing the DNS cache is done using the command line. Go to "Start", select "All Programs", after "Accessories", from the drop-down menu, open "Command Prompt".

In the program that appears, enter the command "ipconfig / flushdns" without brackets.

As a result, the computer itself clears DNS of unnecessary data.

b) Clear thumbnails cache

Cleaning thumbnails cache is done using a standard program.

To run it, follow this path:

1. Go to the start menu.
2. Find in it " All programs".
3. Then " Standard programs».
4. Then "Service".
5. And finally " Disk Cleanup".

You will see a window " Disc selection". Select the hard drive on which Windows is located (usually on drive C).

Now your thumbnails cache is empty.

c) Clear cache

Another way to delete unnecessary temporary documents from your computer

shown in the video:

And do not forget to clean the "Basket", the data in it can also take up a lot of space.

d) Special programs for clearing the cache

To clean up unnecessary data in the “RAM” of a computer, it is convenient to use special programs.

There are many such services developed, but Ccleaner is the most popular.

This program is free. Finding it on the Internet and downloading it to your computer is not difficult.

The official website of the developers, from which you can also download the free version of the program: http://www.piriform.com/CCLEANER

You can also use the online version without installation on a PC.

To clean your PC using Ccleaner, open the program on the "Cleaning" tab.

On the Windows tab, you can select the data that you want to delete. Usually, automatic adjustment accurately determines such documents.

The program will remove unnecessary files from the computer, including those saved by Internet browsers, and from other software.

Click on the "Analysis" button and wait for it to finish. After that, click "Clean".

How to clear browser cache?

If there is no need to delete all temporary documents from the computer, then you can simply clear the memory of Internet browsers. For different Internet browsers, the cleaning methods are slightly different.

1) How to clear memory in Internet Explorer?

On the taskbar or in the main menu, find "Tools" and then "Internet Options".

In the window that appears, you need the "General" tab, where there is a "Browsing History" area. It has a "Delete..." button. By clicking on this button, you will see a window appearing with a list of documents for recycling.

The necessary files are already selected automatically, but you can choose which data to delete. After clicking on the "Delete" button, temporary documents will be deleted.

2) Clearing memory in Firefox

On the main screen, open Settings. In the window that appears, find "Additional" and go to "Network".

This tab has a "Cached Web Content" area with a "Clear Now" button. Click on it, and Firefox will start the analysis and erase the unnecessary.

3) Cleaning memory in Google Chrome

In Google Chrome, find "Tools", then "Show advanced settings".

In some versions of the Internet browser, the path is: “Additional tools” - “Delete browsing data”.

By selecting this item, you will see the "Clear history" window.

Set the recycling period to "All time" and select "Cookies and other data from sites" and "Images stored in the cache." At the end, you need to click "Clear History".

4) Clearing memory in Opera

Go to the "Settings" section. In the window that appears, open the "Security" tab. There is a "Privacy" area with a button "Clear browsing history", click on it.

In the window that appears, select the period "From the very beginning" and note what data needs to be disposed of. Click on "Clear browsing history". Ready.

How to clear the cache on your phone?

Modern phones, more precisely, smartphones and tablets need the same maintenance as personal computers.

They also need to dispose of unnecessary documents. And this should be done more often than on a PC, since the amount of “RAM” is smaller and the system quickly starts to slow down.

1) Clearing memory on Android

There are 3 types of cached memory in the Android operating system:

• dalvik-Cache - optimized application files are stored here;
• system cache - files of system programs are written to it;
• application cache - files of applications such as Internet browsers, games, and so on are stored here.

To clean them, you can use several methods: manually using a standard built-in utility or using additional software.

Ways to clear memory on Android:

For example, consider the Clean Master program:

How to remove temporary "RAM" using CCleaner

see in the video:

2) Clear cache on iPhone

Do not forget to periodically clean your computer and phone from temporary files, because now you know what does it mean to clear the cache- free up space and make the system work easier, thereby increasing its performance and speed.

Hello! Today we will analyze what kind of cached data function is on Samsung phones. You will understand what are their pros and cons of the cache and whether it can be deleted from Android.

In the course of work, on Android smartphones and tablets, residual information about the applications visited and the games launched is accumulated. This information is called a cache. This information is temporary and is constantly updated. Users differently assess the need for cache data on the phone. But most try to immediately delete such temporary files from the device.

Cached data on a Samsung phone

In the latest line of Samsung smartphones (OS Android Lollipop), a new option has appeared - cached data. This function allows you to track the presence of temporary cache files, their volume on the phone and immediately clear the phone of them.

To access this cleaning option, you need to enter " Settings» smartphone and scroll down to « Memory". There, find the cached data and click on it to delete it.

In addition to this option, Samsung phones and tablets provide another form of system cleaning - smart manager. Find it in the main menu of the phone, launch the application and go to the section Memory and in paragraph Unnecessary data click delete. You can also use third-party applications that also have the option of such cleaning. for example Master Cleaner, Cache Cleaner other.

Is it possible to delete the cache?

If you ask yourself the relevance of the issue of deleting temporary cache data, then you should pay attention to several points.

1. If you don't have enough space on your device, deleting cache files is, in principle, done first.
2. The presence of cache data in Android contributes to faster loading of some applications (, Instagram, Classmates, snapchat, mobile browser other).
3. Deleting cache data may affect the launch speed of some applications. This is due to the fact that remembering icons, photos, written text and other information will have to be loaded again. In conditions of weak Internet, it will be very long.
4. Deleting cache files also cleans up residual junk and solves some application errors.

I hope you figured out what cached data is on Samsung phones and drew conclusions for yourself - is it possible delete these files from an Android device.

What is a cache? This is a memory with a high access rate that can be requested with a high probability. The advantage of a cache (buffer) is that it is accessed very quickly. Minus - the amount of cache is limited.

What is cached data? Imagine that you have installed some application on your smartphone. Certain information and data (including settings) that an application needs access to are cached data.

If we are talking about a game on Android, then in this case, cached data means an archive in which the game structures, levels, videos, sound component, etc. are saved.

Do not forget about the cached data stored in the browser. This may include settings, images, files, etc. They are stored in memory and, if necessary, the application, in this case the browser, accesses the cache. So, if you open a previously visited page, then part of the data will not be loaded, but taken from the cache - these can be the same image. What is it for? In order to reduce the page load time in the browser, as well as to save traffic.

We hope you now understand what cached data or simply a cache is on an Android smartphone.

Is it possible and how to delete cached data?

Sometimes cached data needs to be deleted. For example, if the application starts to work incorrectly, it slows down, and often does not load at all. To do this, find the desired application in the section of the same name, for example:

Select Memory.

Click "Clear Cache".

Cached data has been removed.

As for deleting cached data in the browser, this is done through the settings of the web browser. For example, for Google Chrome, open the browser settings.

Then click "Personal".

Now - "Clear history".

Select the files stored in the cache, then click "Delete Data".
