Brand smartphones Samsung are famous for their performance and rich functionality, but even the most powerful models begin to work slower over time. One of the main reasons for slow interface responsiveness and freezing of applications is the overflow of temporary files, known as cache. This data accumulates during the use of the browser, instant messengers, games and social networks, taking up valuable space in the internal memory of the device.
Many users mistakenly believe that deleting the cache will lead to the loss of important photos, contacts or correspondence. In fact clearing the cache does not delete your personal data, logins or passwords, it only erases temporary files, which the system can create again if necessary. Regular memory maintenance helps to avoid critical errors in the operation of applications and extends the period of comfortable use of the gadget without the need to buy a new one.
In this guide, we will analyze in detail all the available methods for freeing up memory on smartphones Galaxy. You'll learn how to use the shell's built-in tools, clear app-specific data, and deep reset the system cache through recovery mode. The correct approach to servicing your phone will allow you to return the device to its former speed. One UI, clear data of specific apps and perform a deep reset of the system cache through recovery mode. The right approach to phone maintenance will allow you to return the device to its former speed.
Why does the cache accumulate and how does it affect the operation of Samsung
The cache is a buffer memory designed to speed up the loading of frequently used data. When you open a web page or launch an application, your smartphone saves certain elements, such as images, scripts and configuration files, so that it doesn't have to be downloaded again from the Internet or disk the next time you access it. Over time, these temporary files can reach several gigabytes in size, which significantly reduces the available space for installing new apps or saving media files.
Excessive cached data not only takes up space, but can also cause conflicts in the operation of the software. If the file in the cache is damaged or out of date after updating the application, the app may begin to work incorrectly, crash, or freeze on startup. In such cases, clearing the cache becomes the only effective way to solve the problem without completely resetting the phone to factory settings.
The cache accumulates especially actively in applications that work with streaming video and social networks. For example, YouTube, Instagram and TikTok save video previews and downloaded feeds to ensure smooth scrolling. Browsers such as Chrome or Samsung Internetstore copies of sites visited. Without regular cleaning, these apps become the main consumers of internal memory, slowing down the entire system. Android.
- 🚀 Speeding up the launch of heavy applications and games by deleting outdated temporary files.
- 🗑️ Freeing up gigabytes of free space for installing system updates or new apps.
- 🛠️ Elimination of errors and failures in the operation of specific services caused by corruption of cache data.
⚠️ Attention: Do not confuse clearing the cache with clearing application data. If you select the “Clear data” option, the app will return to the state immediately after installation, and you will lose all settings, chat history and authorization in this service.
Using the built-in One UI optimizer
Modern smartphones Samsung are equipped with a powerful built-in device maintenance tool, which is located in the settings menu. This optimizer automatically analyzes the system state, identifies background processes consuming resources, and suggests removing unnecessary files. To access it you need to go to Settings → Device Maintenance → Storage. Here you will see detailed statistics on space usage and a button for quick optimization.
The “Clean Now” function allows you to instantly delete temporary files and shut down background applications that are not currently in use. This is the safest and fastest method for the average user, which does not require deep technical knowledge. The system itself determines which files can be deleted without harming the phone's performance, which minimizes the risk of accidentally deleting important information.
In addition to manual cleaning, it is recommended to set up automatic maintenance. In the Auto-optimization section you can set a schedule according to which the phone will independently clear the cache and close unnecessary processes, for example, every night while charging. This approach ensures stable operation of the device on an ongoing basis without the need for regular user intervention in system settings.
☑️ Daily optimization
It is important to note that the built-in optimizer does not always delete the cache of all applications completely, especially if they are actively used in the background. To deeply clean specific apps, such as instant messengers or browsers, you will need an individual approach through the app management menu, which will be discussed in the following sections of this article.
Manual clearing of the cache for individual applications
If you encounter problems with a specific app, for example, Telegram does not load pictures or VKontakte freezes on the main screen, the most effective solution would be to specifically clear the cache of this particular application. This method allows you to free up space and eliminate errors without affecting the data of other apps and the general settings of the smartphone.
To perform this procedure, open the phone settings and go to the Applicationssection. Find the problematic application in the list that appears. If the list is long, use the magnifying glass icon to search by name. After selecting the application, click on the item Memory (or “Storage” in some versions Android), where you will see two buttons: “Clear cache” and “Clear data”.
Click button Clear cache. The system will instantly delete all temporary files associated with this app. The next time you launch the application, it may take a little longer to load than usual because it will have to re-create the necessary temporary files, but this will ensure that you have eliminated a possible source of errors. This method is ideal for serving heavy games and social networks.
What to do if the button is inactive?
If the “Clear cache” button is inactive or missing, try to force stop the application before entering the memory menu. To do this, click “Stop” in the main application information menu, confirm the action, and then go back to the “Memory” section.
It is worth considering that some applications, especially messengers like WhatsApp or Viber, have their own built-in memory management settings. In such cases, it is more effective to use the app's internal tools to clear media files and download history, since system cache clearing may not affect downloaded files stored in application folders.
Clearing the system partition cache via Recovery Mode
Sometimes performance problems affect not individual applications, but the entire system as a whole. In such cases, cleaning the partition Wipe Cache Partition through recovery mode (Recovery Mode) helps. This process deletes temporary files of the operating system itself Androidthat could be damaged after a major firmware update or incorrect operation of the device.
It is important to understand that the key combination to enter recovery mode depends on your model Samsung and version Android. On new models with Android 11 and higher, it is often necessary to connect the smartphone with a cable to the computer before pressing the buttons. On older devices, just use a combination of the Power and Volume keys. Be extremely careful when navigating this menu.
1. Turn off your smartphone completely.2. Connect the USB cable to the computer (for new models).
3. Press the Volume Up + Power button (or Bixby).
4. Hold until the Samsung logo appears, then release.
5. In the Recovery menu, select Wipe Cache Partition.
Navigation in the recovery menu is carried out using the volume buttons (up and down), and the selection of the item is confirmed with the power button. Find the item Wipe Cache Partition, highlight it and confirm your choice. The process will take a few seconds, after which you need to select the item Reboot system now to reboot the phone in normal mode.
⚠️ Attention: In recovery mode, do not under any circumstances select the “Wipe Data/Factory Reset” option unless you plan to completely reset the phone to factory settings and delete all personal files and photos.
If, after updating Android, the phone begins to heat up or quickly discharges, clearing the system cache through Recovery Mode often solves the problem, as it deletes old temporary files of the previous version of the system.
Specifics of clearing the cache in Samsung and Chrome browsers
Browsers are one of the main storage devices for junk files on any smartphone. The built-in browser Samsung Internet and the popular Google Chrome store a huge amount of data to speed up the loading of web pages. However, over time, this leads to sites displaying incorrectly, login forms not working, or the page constantly loading the old version of the content instead of the new one.
In the browser Samsung Internet cleaning is performed through a menu hidden behind three bars in the bottom corner of the screen. Select Settings → Personal data → Delete personal data. Here you can flexibly configure what exactly needs to be deleted: cached images, files, cookies, site data or browsing history. It is recommended to leave checkboxes only on items related to cache and cookies if you do not want to lose saved passwords.
Q Google Chrome The procedure is similar, but the path is slightly different. Click on the three dots in the upper right corner, go to History → Clear history. Select the "Advanced" tab, set the time range to "All time" and check the "Images and other cached files" checkbox. This action will free up a significant amount of memory and force the browser to load the latest versions of sites.
Requires re-logging into accounts on sites

| Clearing option | Impact on operation | Recommendation |
|---|---|---|
| Image cache | Slows down the loading of familiar sites on the first visit | Clear regularly (once a month) |
| Cookies | Clear only if there are problems with authorization | |
| Visit history | Clear if desired for privacy | |
| Passwords | Do not clear without prior export |
Regularly clearing the browser cache solves 90% of problems with incorrect display of web pages and errors when loading content on mobile devices.
Automation of the process and third-party utilities
For users who do not want to constantly manually check the memory of their device, there are ways to automate the cleaning process. The ecosystem Samsung already has the ability to configure scenarios through the app Bixby Routines (or “Modes and Scenarios”). You can create a script that will automatically run memory optimization when connected to a charger or at a certain time of day.
As for third-party applications from the store Google Play, the situation here is ambiguous. Many popular “cleaners” promise miracles of acceleration, but in reality they often consume battery resources and display intrusive advertising. The use of such apps on modern versions Android is often redundant, since the system itself effectively manages memory and forcibly closes background processes when there is a lack of resources.
If you still decide to use third-party software, choose only proven solutions from well-known developers, such as Files by Google. This app securely analyzes your device, finds duplicate files, large videos, and unused apps and suggests deleting them. It does not require advanced access rights and does not aggressively interfere with system processes, like many dubious utilities.
- 🤖 Use built-in scripts Bixby Routines for automatic nightly cleaning.
- 📁 Application Files by Google is a reliable tool for searching and deleting garbage.
- 🚫 Avoid installing aggressive antiviruses with the “acceleration” function, they often harm the system.
⚠️ Attention: Interfaces and names of menu items may vary slightly depending on the version of the One UI shell and the model of your smartphone. If you do not find the described item, use the settings search (magnifying glass icon at the top of the settings screen).
