Modern smartphones, such as Realme 8, have powerful hardware, but over time they accumulate a huge amount of temporary data. These files, called caches, are designed to speed up applications, but when they accumulate in excess, they begin to slow down the system and take up precious space in the internal memory. Users often notice that the device begins to work slower, and notifications about low space appear more often.
The process of clearing the cache on the shell Realme UI, which is based on Android, may not seem obvious due to different firmware versions and interface updates. It's important to understand the difference between clearing the cache of a specific application, clearing the system cache through the recovery menu, and using built-in optimization utilities. Incorrect actions can lead to the loss of important settings or logins, so you need to approach the procedure consciously.
In this article we will analyze in detail all the available methods for freeing up memory on your device. We will look at standard system tools, hidden engineering menus and third-party solutions. You will learn which files can be deleted without fear, and which files are strictly not recommended to be touched. Proper cleaning will return your smartphone to its former speed of responsiveness.
Memory fullness analysis and diagnostics
Before taking radical measures, you need to understand what exactly is taking up space in your memory Realme 8. The Android system stores data in multiple partitions, and not all of them can be directly cleared by the user. The first step should always be diagnostics through the built-in tools, which will give an accurate picture of the space distribution.
To do this, go to the device settings and select the section About the phone, and then click on the item Storage. Here you will see a visual diagram where systems, applications, images, videos and other garbage are indicated in different colors. Pay attention to the “Other” or “Miscellaneous” item - often this is where giant cache files of instant messengers and social networks are hidden, which the system does not always classify correctly.
If the amount of occupied memory exceeds 85-90%, the system begins to artificially limit the speed of the processor in order to prevent overheating and failures. Cached data in this case they become not a helper, but a brake. Regular monitoring of the content allows you to delete unnecessary things before the phone starts to hang.
⚠️ Attention: Do not delete files from system folders through the file manager if you are not 100% sure of their purpose. This may lead to some phone functions not working.
Clearing the cache of individual applications through settings
The safest and most accurate method of freeing up space is to manually clear the cache for each specific application. This method does not affect your personal data, logins or passwords, deleting only temporary files that the app downloaded for quick access. For example, the browser stores pictures from visited sites, and YouTube stores video thumbnails.
To perform this operation, open the menu Settings and go to the section Applications. Find the desired app in the list, for example Instagram or Chrome. After entering the application menu, select Memory usage or Storage. There you will see two buttons: “Clear data” and “Clear cache”. We are interested in the second one.
Click on the button Clear cache. The system will instantly delete temporary files, and you will see how several hundred megabytes or even gigabytes of space have been freed up. Repeat this procedure for all resource-intensive applications that you use daily. This is especially true for social networks and instant messengers, which tend to accumulate gigabytes of media files.
☑️ Checking leading applications by cache size
It is worth noting that after clearing the cache, the application may take a little longer to load when first launched, since it will have to re-download the necessary resources from the network. However, this is a one-time delay, which is fully compensated by the freed up space and the stability of the system as a whole.
Using the built-in Realme cleaning manager
In the shell Realme UI a special application “Phone Manager” is preinstalled, which automates the cleaning process. This is a handy tool for those who don't want to manually go through each application. The system algorithms independently analyze the storage and offer to remove obvious garbage, duplicate files and outdated installation packages.
Run the application Phone Manager from the main screen or from the tools folder. On the main page you will see a large button Cleaning indicating the volume of files that can be safely deleted. Click on it, the system will scan the device and offer a list of files to delete. You can deselect (uncheck) those items that you want to save.
In addition to simple cleaning, this menu has sections for managing large files and duplicate photos. The function Deep Clean allows you to find forgotten downloads and empty folders. This is an effective way to quickly get back a few gigabytes of free space without the risk of deleting anything important, since Realme's algorithms are quite conservative in their recommendations.
Use the Phone Cooling feature in the manager after clearing the cache to reset background processes and reduce CPU load.
However, it is worth remembering that automatic cleaners do not always see the cache inside messengers, since they consider this data important for the operation of the app. Therefore, a combination of automatic cleaning and manual checking of application settings gives the best result.
Clearing the system cache via Recovery Mode
There is a more advanced method that deletes temporary files of the entire operating system, rather than individual applications. This method is called clearing the cache partition through recovery mode (Recovery Mode). It is useful in cases where the phone begins to work unstable after a major firmware update or installation of many apps.
To enter this mode, you must completely turn off the smartphone Realme 8. Then hold down the Volume Down button and the Power button at the same time. Hold them until the logo appears Realme, then release the power button, but continue to hold the volume button until the language selection menu appears.
In the recovery menu, control is carried out by the volume buttons (up and down) and the power button (select). Select the language English, then go to Wipe data. In some firmware versions this item may be called Format data. Here it is important to select the option Wipe cache partitionif it is available separately, or simply clear the cache without touching user data.
| Action | Risk of data loss | Difficulty | Efficiency |
|---|---|---|---|
| Clearing application cache | No | Low | Average |
| Phone manager | No | Low | Medium |
| Recovery Mode (Cache) | No (if chosen correctly) | High | High |
| Reset to factory settings | Total loss | Average | Maximum |
⚠️ Attention: In the Recovery menu, be extremely careful. Selecting "Wipe Data" or "Format Data" will completely delete all your photos, contacts and applications. Select only options containing the word "Cache".
What to do if the phone is not included in Recovery?
If the button combination does not work, try connecting the switched off phone to the computer via a USB cable, and then hold down the power and volume buttons. On some versions of Realme UI, entry is only possible when the charger is connected.
Features of clearing the cache in messengers
Messengers such as Telegram, WhatsApp and Viberdeserve special attention. These applications have their own internal mechanisms for caching media files, which are often not visible by standard Android system tools. They can take up up to 10-20 GB of memory, storing thousands of viewed photos and videos.
V Telegram cleaning is done inside the application itself. Go to Settings → Data and memory → Memory usage. There you will see a button Clear cache. A unique feature of this messenger is the ability to set a cache size limit, for example, 500 MB. When the limit is reached, old files will be deleted automatically.
In WhatsApp the situation is a little different. Go to Settings → Data and storage → Storage management. Here you can see a list of chats that take up the most space and delete media files selectively. This allows you to clear the cache of heavy videos, while saving important correspondence and documents.
Regularly setting up media auto-loading in these applications will help prevent the memory from quickly filling up again. Disable automatic downloading of photos and videos on the mobile network so that the cache does not grow in the background without your knowledge.
Setting a cache limit in Telegram is a “one-time action” that will save you from the need for manual cleaning in the future.
Prevention and maintenance of system cleanliness
To prevent the question “how to clear the cache on Realme 8” from arising every month, it is necessary to implement simple rules of digital hygiene. Constant memory fragmentation and accumulation of error logs can reduce the performance of the eMMC or UFS drive on which your smartphone runs.
It is recommended to check the Downloads (Downloads) folder once a week. Often there are many APK installation files that are no longer needed after installing apps, as well as PDF documents and images from the browser. Deleting them is safe and effective.
- 🗑️ Delete unnecessary screenshots and edited versions of photos immediately after processing.
- 📦 Disable auto-update of applications via the mobile network to avoid downloading unnecessary data in the background mode.
- 🔄 Restart your smartphone at least once every 3-4 days to reset system temporary files from RAM.
It is also worth paying attention to widgets and live wallpapers. They constantly consume resources and can create their own cache files for animation. Replacing them with static images can not only save space, but also extend battery life.
⚠️ Note: The interface and menu names may vary slightly depending on the version of Realme UI (2.0, 3.0, 4.0). If you don't find an item, use the settings search at the top of the screen.
Frequently asked questions (FAQ)
Will clearing the cache delete my photos and contacts?
No, clearing the cache only affects temporary application files. Your personal data such as photos, contacts, messages and notes will remain completely safe. However, if you click the “Clear Data” button, the application will reset to the “as after installation” state and you will lose logins and settings inside that particular application.
How often should you clear the cache on Realme 8?
There is no specific frequency. Do this as needed: when a notification appears about low space or when you notice that your phone is starting to slow down. For modern versions of Android, frequent forced clearing of the cache is not required, since the system can manage temporary files itself.
Why did little space free up after clearing the cache?
Perhaps the bulk of the memory is occupied not by temporary cache files, but by the applications themselves, games, photos and videos. In this case, clearing the cache will only have a temporary effect. It is recommended to check the storage and delete large files or transfer media to a memory card or to the cloud.
Is it safe to use third-party apps like Clean Master?
Experts do not recommend installing aggressive cleaners on modern smartphones. They often run in the background, consuming battery and displaying advertisements. The built-in Realme manager and manual cleaning are quite enough to maintain the health of the system.
What to do if the application cache is cleared, but quickly grows again?
This is normal behavior for some applications (for example, maps or streaming services) that constantly load new content. If the growth is abnormally fast, try updating the application to the latest version or reinstalling it, as this may be a sign of a software error.
