Xiaomi and Redmi are famous for their excellent price-performance ratio, but over time, even the most powerful devices can start to work slower. One of the most common reasons for the slowdown is overflow of accumulated temporary information. Many users notice that the phone begins to slow down or apps open longer, without even knowing that the problem is solved by a simple maintenance procedure.
Temporary files are a natural process for Android and MIUI. Browsers save images from visited sites, messengers store preview photos, and app stores store installation packages. If you ignore this state, the free space ends and the system begins to work in stress mode. Understanding how to properly manage this data is a key skill for any Android smartphone owner.
In this article, we will take a look at all available cleaning methods, from standard system tools to advanced tools for power users. You will learn to distinguish between memory types, safely remove debris and avoid critical errors. Proper hygiene of a digital device extends its life and provides comfort in daily use.
Before we go into action, it's important to understand the difference between app data and cache. Deleting the cache is safe for your personal correspondence, accounts and game progress. However, erasing the application data will result in its complete reset to factory state, which will require re-authorization. Be careful when choosing the type of cleaning.
Types of cache in the Android system
The operating system divides temporary files into several categories, each of which performs its function. The system cache contains the data necessary for the operation of the OS itself, drivers and basic services of Google. Its cleaning usually occurs automatically after a restart or update, but sometimes manual intervention is required if the system behaves unstable.
The second type is the app cache, which is the largest piece of junk that accumulates in the process of use, and social networks, browsers and video hostings create gigabytes of temporary files to speed up the loading of content when you re-access, for example, by browsing Instagram feeds, you upload hundreds of images that are stored in your phone's memory.
⚠️ Warning: Don't confuse cache cleaning with data deletion.Cache clearing frees up space and doesn't affect your logins and passwords, whereas data deletion completely resets the app.
The third type is the Dalwick/ART cache, which is optimized versions of applications for faster launch, which is hidden from the average user and is only affected by resetting settings or deep cleaning through the recovery menu.
Understanding the structure of files allows you to act point by point. It makes no sense to delete everything if the problem is in one “heavy” application. Analysis of memory consumption helps to identify the culprits of the slowdown of the Xiaomi device.
Use of the built-in Security application
The MIUI shell and its successor HyperOS have powerful built-in tools to maintain the system. The standard Security app already contains all the necessary features for quick cleaning, and installing third-party programs is often unnecessary. This is the first step every smartphone owner should take.
To start the procedure, look for an icon on your desktop called "Security" or "Security", usually green with a shield. Inside the interface, select "Clean Up" and the system will automatically analyze the device and show the amount of junk files that can be deleted without risking stability.
☑️ Checking before cleaning
Once you press the clean button, the system will delete temporary files, residues from deleted applications and empty folders, but for a deeper work, you should go to the Memory section inside the application, where you can analyze in detail which programs occupy the most space, and clean them individually.
The Acceleration feature in the same app helps free up RAM by closing the background. While Android can manage RAM itself, on devices with a small amount of storage (3-4 GB), manual cleaning before launching heavy games or cameras can give a tangible boost to performance.
💡
Run a complete cleanup through the Safety app at least once a week to keep the system on track and avoid a critical mass of debris.
Manually cleaning the cache of individual applications
Sometimes automated systems can't handle specific bloated programs like Telegram, TikTok or YouTube, and in such cases, manual intervention through system settings is required, freeing up gigabytes of space that are taken up by the videos and images viewed.
To get to the settings, go to the Settings menu → Applications → All applications. In the list that opens, find the program you want. Pay attention to the Memory or Storage section inside the application card, which will display the amount of space occupied and the cache volume separately.
Click the "Clear Cache" button. If you see that the application takes up too much space due to accumulated data (for example, card cache or offline music) and you do not need this data, you can choose "Clear All" or "Delete Data", but remember the consequences of leaving your account.
| Annex | Type of data | Recommended action | Risk of data loss |
|---|---|---|---|
| Google Chrome | Cash images. | Clear the cache | No. |
| Telegram | Media files | Clean through Telegram settings | No (will stay in the cloud) |
| YouTube | Temporary files | Clear the cache | No. |
| Cash tapes | Clear the cache | No. | |
| Google Maps | Offline maps | Clear the data (if no cards are needed) | High (card removal) |
Pay special attention to messengers, for example, Telegram is better to use the built-in cache cleaning function in the section "Data and memory", which allows you to flexibly configure automatic deletion of old files, which is much more effective than manual cleaning through the Android settings.
Regularly checking heavy apps is a good habit. If you notice that a program has started to take up a disproportionate amount of space, check its settings. Often there are options to limit cache size or autodelete media files.
Cleaning through the Recovery menu (Recovery Mode)
For more advanced users, there is a method of cleaning the system cache through the recovery menu, which is useful if after updating Xiaomi firmware there are errors, cyclical reboots or strange behavior of the system, it deletes temporary system files without affecting the user’s personal data.
To enter Recovery mode on Xiaomi, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, after which the phone will go to the main Recovery menu.
What to do if the Recovery menu does not open?
The menu uses volume buttons (up/down) and the power button to confirm the choice. Find the Wipe Cache Partition. Be very careful not to confuse this with Wipe Data, which will completely delete all your files and reset your phone to factory settings.
⚠️ Warning: There is no back button in the Recovery menu. One wrong move can result in all data being lost.
Once confirmed, the system will clear the system cache, which takes seconds or minutes depending on the amount of debris accumulated. Upon completion, select Reboot to start the system as normal. The first boot may take longer than usual.
Third-party utilities and their effectiveness
There are thousands of memory-cleaning apps in the Google Play store, and popular names like CCleaner, Files by Google, or Clean Master promise speed miracles, but it’s worth exploring whether they’re really needed on today’s Xiaomi smartphones.
On the one hand, specialized ulites can find duplicate photos, old files in the Download folder and remnants of deleted applications that a standard cleaner misses. On the other hand, aggressive "cleaners" can consume resources, show ads and even slow down the phone with constant background checks.
The safest and most recommended option is to use Files by Google, which is deeply integrated, free of intrusive advertising, and can safely remove screenshots, memes, and large files. The built-in MIUI functionality in conjunction with Files by Google covers 99% of user needs.
Using dubious applications with names like Super Fast Cleaner 2026 often backfires: They can request excessive permissions, collect user data, and load the processor, and spend 5 minutes manually disassembling storage than installing potentially dangerous software.
💡
The standard MIUI tools and Files by Google app are enough to fully service your smartphone. Avoid installing unknown cliners.
Prevention and optimization of memory
To avoid memory problems on a regular basis, you need to implement a few simple habits: First, set up automatic cleaning in messengers, Telegram and WhatsApp can set a timer for the life of media files so that they do not accumulate forever.
Second, use cloud storage, photos and videos take up the lion's share of memory, services like Google Photos or Xiaomi Cloud allow you to store media in the cloud, leaving only thumbnails on the device, which frees up gigabytes of space.
Third, keep an eye out for system updates. Xiaomi engineers are constantly optimizing the file system and cleaning mechanisms in new versions of Android and MIUI. Ignoring updates can deprive you of improvements in memory management.
It's also helpful to check the Download folder periodically. APK-file, PDF-Documents and images from browsers that have long since lost their relevance. Regular "digital cleaning" keeps your smartphone fast.
Remember that filling internal memory by more than 90% critically affects the speed of flash memory. Try to keep at least 10-15% of the total storage capacity free for comfortable operation of the system.
