Xiaomi’s Redmi Note 8 Pro series has been popular for years due to its excellent price-performance ratio. However, over time, even the powerful Helio G90T processor may begin to experience difficulty processing tasks due to accumulated garbage in the system. The main culprit for slowdowns and lack of free memory is often the cache of applications and system services, which grows to gigabytes.
Cache cleaning is not just a way to free up space, but also an effective way to solve problems with freezes, malfunctions and incorrect content updates. Unlike a complete reset, this procedure is completely safe for your personal data if done correctly. In this article, we will discuss in detail all available methods for cleaning memory on MIUI, including hidden functions and specialized tools.
Before you start taking action, it is important to understand the difference between the types of data being cleared. Cache are temporary files that speed up the load of frequently used items, whereas application data contains your logins, settings and game progress. Incorrect deleting information can lead to the need for re-authorization on social networks or messengers, so you should carefully follow the instructions below.
Understanding the Cache Structure in MIUI
The MIUI operating shell installed on the Redmi Note 8 Pro has a specific file system other than pure Android. Here the cache is divided into several categories: system cache, application cache, browser cache and remnants of remote programs. Understanding this structure allows for deeper and more efficient cleaning without affecting critical operating system files.
System cache often contains temporary update files and error logs that can take up a significant amount of space, while applications create their own temporary data stores for quick operation, such as social networks store images viewed here, and navigators store maps of the areas you visited, accumulating these files over time leads to fragmentation of memory and reduces the response speed of the interface.
⚠️ Warning: Don't try to manually delete files from system folders through a file manager unless you know exactly what they're responsible for.This could lead to an unstable Redmi Note 8 Pro or cyclical reboot.
It's important for the user to know that standard cleaning products often only remove the surface layer of debris. Deep cleaning requires access to specialized menus or use of an engineering mode. However, in most cases, there are enough standard tools, which we will discuss next, the main thing is the regularity of maintenance procedures.
💡
Use Do Not Disturb before clearing the cache so that background processes do not create new temporary files during the procedure.
Cleaning the cache through the standard Security app
The easiest and safest way to free up space on the Xiaomi Redmi Note 8 Pro is to use the built-in Security app, which is designed specifically for the MIUI shell and is able to find hidden temporary files that are not visible during normal storage browsing. It takes only a few seconds to start scanning and does not require superuser rights.
Once the application is launched, you need to click on a large green scan button. The system will analyze the installed programs and determine the amount of cache they occupy. Unlike third-party utilities, the built-in scanner knows the specifics of Xiaomi's system processes and does not label important files as garbage. Once the analysis is completed, you will be asked to clean up the found.
- 📱 Click on the Cleanup icon in the main menu of the Security app.
- 🔍 Wait for the automatic scanning of the system to be completed.
- 🗑️ Click the Clear button to delete temporary files.
- 📂 For a detailed check, go to the Deep Cleanup section.
Deep Clean allows you to manually select file categories to delete, such as large files, unused apps or duplicate photos. This is especially useful if standard cleaning has not produced the desired result.
☑️ Checking before cleaning
Removing the cache of individual applications manually
Sometimes the problem isn't the total amount of garbage, but a specific application that mismanages its temporary files. On the Redmi Note 8 Pro, you can force the cache of any program through system settings, a method that is particularly effective for instant messengers like Telegram or WhatsApp, which tend to accumulate gigabytes of media cache.
To do this, go to the Settings menu and select the Apps section. Next, click All apps to see the full list of installed software. Find a problem program like YouTube or Instagram on the list and open its properties. Here you are interested in the Clean button located at the bottom of the screen.
When you click on this button, the system will offer two options: Clear the cache and Clear everything. The first option deletes only temporary files, saving your logins and settings. The second option completely resets the application to the "post-installation" state, deleting all data. Be careful when choosing to not lose important information.
| Action. | What's removed | Is login to the account maintained? | Impact on data |
|---|---|---|---|
| Clear the cache | Temporary files, thumbnails | Yes. | Safe. |
| Clear it all up. | Cash, settings, logins, databases | No. | Total reset |
| Delete the appendix | All program files and data | No. | Removal |
| Stop it. | Nothing (just the process) | Yes. | Safe. |
If the app continues to work incorrectly after cleaning the cache, perform the Stop action and then restart it, which allows you to restart all the processes associated with the program on the Android system. In some cases, it also helps to remove application updates through the tripoint menu in the upper right corner of the program properties screen.
Why does the cache fill up quickly?
Using Developer Mode for Advanced Cleaning
For Redmi Note 8 Pro users who want to gain maximum control over the system, there is a developer mode, activating this mode opens up access to hidden memory and process management functions, a powerful tool that allows not only to clear the cache, but also to limit the background activity of applications, which indirectly reduces the amount of garbage created.
To activate Developer Mode, go to Settings → About Phone. Find the MIUI Version string and quickly click on it 7 times in a row. The system will notify you that you have become a developer. Then a new Developer Settings item will appear in the Advanced Settings menu. Here you can find the Do Not Leave Activity option that will destroy background processes immediately after you use them.
The developer menu also includes the Start Up Services feature, where you can see which processes consume the most resources. Although there is no direct button to clear all cache, the memory management in this section prevents overflows. You can limit the number of background processes, which will cause the system to more aggressively unload the cache from RAM.
⚠️ Note: Changing the settings in the "Developers" menu may affect the stability of the Redmi Note 8 Pro. Do not change the values that you are not sure about, especially the options associated with animation or debugging. USB.
One of the useful functions for cleaning is resetting settings. ADB (Android Debug Bridge, if you've previously connected your phone to your computer for debugging. USB" And then you turn it off, and you reset the debugging permissions, and it helps to eliminate the software conflicts that sometimes lead to the accumulation of erroneous logs.
Cleaning the cache through Recovery Mode
The most radical but effective method is to clean the Wipe Cache Partition through the Recovery Mode menu, which removes the system cache that is not accessible through the normal MIUI interface.
To enter recovery mode on the Xiaomi Redmi Note 8 Pro, you need to turn the device off completely. Then press the Volume Up and Power buttons at the same time. Hold them until the Mi logo appears, after which the phone will go to the main Recovery menu. The control here is carried out by volume buttons (up / down), and the choice is confirmed by the power button.
Instructions for navigation in Recovery:
Volume Up - Moving the cursor up
Volume Down - Moving the cursor down
Food - Confirmation of Choice (Enter)From the menu, select Wipe Data and then Wipe Cache. The system will warn you of the consequences, but as mentioned, personal files will not be affected. Once the process is complete, select Back to Main Menu and then Reboot → Reboot to System. The first download after this procedure may take longer than usual, as the system will recreate the necessary temporary files.
💡
Cleaning through Recovery Mode is the best way to fix system errors and freezes that are not solved by conventional cleaning through settings.
Prevention and optimization of storage
To avoid running into overcrowded memory on the Redmi Note 8 Pro too often, it’s worth implementing a few device maintenance habits. Regular prevention takes less time than dealing with the effects of clogged storage. Modern versions of MIUI offer automation tools that are worth configuring once.
The Security app has a Memory Acceleration feature that you can run before heavy tasks begin. It is also recommended to periodically check the Download folder and the gallery basket, since deleted photos are often stored there for another 30 days, taking up space. Automatic cleaning of the basket will help keep the device in good shape.
- 🧹 Remove unused apps as soon as you realize they are not needed.
- 📸 Set up cloud sync photos to store originals in the cloud, not in your phone’s memory.
- 🔄 Update apps regularly through Google Play, as newer versions often include cache optimization.
- 🚫 Turn off autoplay videos on social media to save traffic and cache.
Using microSD cards can also be a solution if the model supports extension, and by moving media and documents to an external medium, you free up internal memory for the system and application cache, but it is worth remembering that the speed of applications installed on the memory card can be lower.
