Smartphones of the line Xiaomi Redmi 8, despite their age, remain popular due to their reliability and affordability. However, over time, owners often experience device slowdowns, sudden freezes, or lack of free memory space. One of the most effective measures to restore performance is regular cleaning the cache, which allows you to remove accumulated temporary garbage without losing personal data.
In the system MIUIinstalled on these devices, cleaning procedures may differ from the standard Android due to the peculiarities of the proprietary shell. Users often confuse clearing the cache of individual applications with a complete system wipe or factory reset. In this article, we will look in detail at safe methods for deleting temporary files so that your Redmi 8 works quickly and stably again.
Understanding what exactly you are deleting is critical to maintaining the functionality of your phone. The cache is not your photos or contacts, but temporary data that apps create to speed up loading times. Let's look at how to competently manage this process using built-in tools and hidden system capabilities.
What is cache and why it needs to be cleared on Redmi 8
The cache is a memory area where applications store temporary files: image thumbnails, web page data, intermediate calculation results. This is done so that when accessing the same data again, the app will work faster and not waste Internet traffic. On a device with limited internal memory like Redmi 8, these files can take up gigabytes of space.
Over time, the cache can become damaged or become redundant. For example, if the application has been updated, but old temporary files remain, this may cause app conflicts. As a result, you experience interface slowdowns, increased battery consumption, or even forced closure of apps. Regular cleaning helps prevent these problems.
It is worth distinguishing between the application cache and the system cache. The first relates to specific apps (for example, YouTube or Telegram), the second - to the operation of the operating system itself. The first type of cleaning is absolutely safe and does not require a reboot. The second type requires a more careful approach, especially on modern versions Androidwhere access to the system cache partition is limited.
⚠️ Attention: Clearing the cache does not delete your logins, passwords, correspondence or saved files. However, in some rare cases, applications may reset their settings to default, so be prepared to log in to the services again.
On Xiaomi Redmi 8 memory management is closely related to the operation of the shell MIUI. The system automatically tries to optimize the process, but manual intervention often gives the best result, especially if the phone has been actively used for several years.
Built-in “Security” application for quick cleaning
The easiest and recommended method for ordinary users is to use a pre-installed application Security. This is a system tool that combines antivirus, garbage cleaning and permission management. It automatically scans your device for unnecessary files.
To start the procedure, find the green shield icon on your desktop. After opening the application, click on the button Cleanup. The system will analyze the memory and show the amount of data that can be safely deleted. Typically this includes cache files, remnants of uninstalled apps, and adware.
- 🧹 Click the "Clean" button to remove any junk found.
- 📱 Check the "Deep Cleaning" section to find large files.
- ⚙️ Configure automatic cleaning in the application settings.
It is important to note that the algorithms MIUI can be quite aggressive. Sometimes the list of candidates for deletion includes files that you planned to keep. Therefore, before the final confirmation, always look through the list of files, especially if you use your phone to work with documents.
Set up automatic garbage cleaning in the Security application so that the phone itself deletes the cache when the amount of free memory drops below 10%.
Deep cleaning function allows you to find duplicate photos, old installation files APK and unnecessary data packets. This is especially true for Redmi 8, since its internal memory is often filled to capacity with media files.
Manually clearing the cache of individual applications through the settings
If the problem with the brakes is related to a specific app, for example Instagram or a browser, there is no need to clean the entire phone. You can specifically delete the cache for this application only. This is done through the standard settings menu Android.
Go to section Settings, then select item Applications. Find the desired app in the list. Inside the application menu you will see a button Memory or Storage. There will be two main buttons: “Clear cache” and “Clear everything.”
It is extremely important to press this "Clear cache". The Clear All (or Reset) button will delete all application data, including your accounts and settings. This is equivalent to a complete reinstallation of the app. Use this option only in extreme cases when the application does not work correctly.
Settings → Applications → [Select application] → Storage → Clear cacheFor system applications such as Gallery or Phone, the procedure is similar. However, here you need to be even more careful. Clearing the gallery cache will force the system to rescan all photos to create thumbnails, which can temporarily load the processor.
☑️ Check before clearing the application
Using Recovery mode for system cleaning
A more advanced method involves using recovery mode Recovery. This method allows you to clear the system cache partition (Dalvik Cache), which is not accessible from the normal interface. This can help if the phone freezes during the boot phase or is extremely unstable.
To enter this mode, you must turn off the smartphone Redmi 8. Then hold down the Volume Up button and the Power button at the same time. Hold them until the logo Miappears, then release the power button, but continue to hold the volume down. You will be taken to the main menu Recovery.
Navigation in this menu is carried out using the volume buttons (up and down), and the selection is confirmed with the power button. Find item Wipe Data. There may be an option inside it Wipe Cache. Be extremely careful: do not confuse this item with Wipe All Data, which will erase the entire phone.
⚠️ Attention: In new versions of MIUI, the option to clear the cache separately in the Recovery menu may not be available. If you only see “Wipe All Data,” don’t click it unless you want to lose all your files. In this case, use clearing methods through the settings.
After successfully clearing the cache, select Rebootto reboot the system. The first launch after such a procedure may take longer than usual, since the system will recreate optimized files for applications.
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 buttons. Sometimes this helps to activate the recovery mode.
Comparison of cleaning methods and their effect on the system
Different cleaning methods have different degrees of effectiveness and risk. It is important for the user to understand which tool to use in a particular situation. Below is a table comparing the main methods for deleting temporary files by Xiaomi Redmi 8.
| Cleaning method | Security | Efficiency | Risk of data loss |
|---|---|---|---|
| Security application | High | Medium | Absent |
| Application settings | High | High (spotted) | Low (settings only) |
| Recovery mode | Medium | Maximum | Medium (user error) |
| Third-party utilities | Low | Average | High (advertising, viruses) |
The use of third-party apps from Google Play, such as Clean Master or analogues, is often not recommended on modern versions. Android. The system itself effectively manages memory, and unnecessary apps only waste resources and show intrusive advertising.
The most balanced approach is a combination of a built-in application Security for regular maintenance and manual cleaning of “heavy” applications through the settings. The mode Recovery should be left as an emergency option to solve serious software failures.
Regularly clearing the cache extends the life of the phone's storage, reducing the number of cycles of rewriting memory cells and preventing logical errors in the file system.
Prevention of memory clogging and optimization of work
To avoid having to constantly struggle with lack of space, it is worth introducing several habits of using your smartphone. First, disable automatic saving of media files in instant messengers. You can set a ban on downloading photos and videos when using mobile data. Secondly, periodically check the folder (Downloads). Installation files, documents and pictures that are no longer needed often accumulate there. Deleting these files frees up space instantly and does not affect the operation of the system. WhatsApp And Telegram You can set a ban on downloading photos and videos when using mobile data.
Secondly, check the folder periodically Download (Downloads). Installation files, documents and pictures that are no longer needed often accumulate there. Deleting these files frees up space instantly and does not affect system performance.
- 📸 Disable autosaving in social networks.
- 🗑️ Clean out the "Downloads" folder regularly.
- ☁️ Use cloud storage for photos and video.
It is also worth paying attention to the “Memory Expansion” function, if it is available in your firmware version. It uses part of the internal storage as virtual RAM. While this can help with multitasking, it also increases wear and tear on the main drive.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of MIUI (Global, Russia, China). If you don't find the specified button, look for a similar icon or use the settings search.
Following these simple rules will allow your Redmi 8 remain responsive much longer. Remember that the full amount of memory (when less than 500 MB is free) always leads to a critical slowdown of any smartphone.
Frequently asked questions (FAQ)
Will my WhatsApp correspondence be deleted when clearing the cache?
No, when you click the “Clear cache” button, your correspondence, photographs and contacts will remain in place. Only temporary files necessary for the application to run quickly will be deleted. If you click “Clear all” (Data), the correspondence will be deleted.
How often should you clear the cache on Xiaomi Redmi 8?
It is enough to carry out a complete cleaning through the “Security” application once every 1-2 weeks. You should only do manual cleaning of specific applications if you notice that they are running slowly or taking up an abnormally large amount of space.
Why is the space not freed up after clearing the cache?
Some applications (for example, maps or streaming services) may immediately begin loading a new cache upon first launch. Also, make sure you clear the cache and not just delete shortcuts or temporary files from the trash.
Is it possible to delete the Android system process cache?
The system cache (Dalvik/ART cache) is cleared only through Recovery mode or automatically after updating the system. In normal mode, the settings are hidden to prevent unstable operation of the phone. It is not recommended to interfere with this process unnecessarily.
Does clearing the cache affect battery life?
Indirectly - yes. If an app doesn't work properly due to a corrupted cache, it may consume more CPU resources, which drains your battery. After cleaning, operation returns to normal and energy consumption may decrease.
