Redmi and Xiaomi are famous for their performance and affordable price, but over time, even the most powerful devices start to work slower. One of the main reasons for the slowdown is the accumulation of temporary files known as cache. This data is created by applications to speed up their re-start, but over time can take up gigabytes of usable space and cause system conflicts. Understanding how to remove cache in shaomi redmi is a basic skill for any owner of this device who wants to keep the phone in optimal condition.
With Android, which runs the MIUI or HyperOS shell, the application backgrounds are very aggressive, which means that even if you’re not using the program right now, it can continue to collect information and save temporary data. Regularly cleaning up these files not only makes room for your photos and videos, but also often solves problems with app crashes or incorrect content display. In this article, we’ll take a look at all the cleaning methods available, from simple built-in tools to advanced settings for power users.
It is important to note that deleting cache is a safe procedure that does not affect your personal data, such as contacts, messages or pictures taken. However, there are nuances that you need to know before starting the procedure, so as not to disrupt some services. We will look at the differences between cleaning a particular application and completely cleaning the system, and also explain when to resort to more radical measures.
What is cache and why should it be removed on Redmi?
Cache is a buffer memory in which applications store temporary files to quickly access frequently used data. When you open a social network, browser or game, the device downloads images, scripts and other interface elements, storing them locally, which allows you not to download information again from the Internet on the next run, which saves traffic and speeds up the program. However, over time, the size of these temporary files can grow to unimaginable proportions, occupying precious space in internal memory.
The problem is that Android’s automatic cleaning mechanisms don’t always work correctly. Apps can store erroneous or corrupted data that causes malfunctions. For example, if you notice that YouTube loads videos for a long time or Instagram suddenly shuts down, it’s likely that the culprit is a crowded or damaged cache. Regular maintenance helps avoid such situations and prolongs the life of the smartphone drive, reducing the load on it.
⚠️ Cache clearing does not delete your logins, passwords or game progress.However, in some cases (for example, browsers) you may need to re-authorize on sites, since session data can also be stored in temporary files.
There is a misconception that constantly cleaning the cache harms the battery or the processor. In fact, a one-time removal of junk files gives the system a breath of fresh air. Another thing is, if you do this every five minutes, then the phone will constantly waste resources on re-generation of these files, which can really reduce autonomy. The optimal frequency of the procedure depends on the intensity of the device's use, but usually it is enough to do it once in one or two weeks.
💡
Use Do Not Disturb before clearing the heavy app cache so that the system does not interrupt the process with background notifications and calls.
Use of the built-in "Security" application
The easiest and most affordable way to clean up the cache on Xiaomi Redmi is to use a regular system application. The company has built powerful tools to service the device directly out of the box, which saves users from having to download third-party software. This method is ideal for quickly preventing and removing obvious debris that accumulates as a result of everyday smartphone use.
To start, look for an icon on your desktop or in the Tools folder called Security. When you run the app, you'll see a large green indicator showing the current state of the system. Click the Cleanup button (usually located in the center or top of the screen). The system will automatically scan and prompt you to delete the files found. This process takes only a few seconds and is completely safe for the stability of MIUI.
☑️ Cleaning algorithm through Security application
Once the initial cleanup is complete, you should go to the Cleanup section of the app for more detailed analysis, where the system will suggest removing old APK installer files, unnecessary data packets, and remnants of deleted programs. Notice the Big Files section, which often hides forgotten videos or archives that can also be safely deleted if you no longer need them, and this comprehensive approach allows you to free up to several gigabytes of space in just a few minutes.
It's important to understand that the built-in tool doesn't always remove the cache of all applications deeply. It focuses on standard ways of storing temporary data. If a particular program continues to malfunction even after a general cleanup, a more targeted approach will be required, which we'll discuss in the next sections. However, this method is quite sufficient in most cases to maintain general system hygiene.
Clearing the cache of individual applications through settings
When the problem is just one particular program, it doesn't make sense to clean the entire phone. Android has a customized memory management for each application installed. This is especially true for "heavy" programs like TikTok, Telegram or navigators, which tend to accumulate huge amounts of temporary data. To get into the desired menu, open Settings and select the App.
In the list that opens, find a problem app. For example, if you want to clear your browser cache, look for Chrome or Mi Browser. When you go to the app page, click on Memory (or Storage). Here you will see two main buttons: Clear cache and Clear all (or Reset), it is critical not to confuse these features. The first deletes only temporary files, the second deletes all data, including logins and settings, returning the application to state immediately after installation.
What is the difference between "Clean Cache" and "Clean Everything"?
For instant messengers like WhatsApp or Viber, the situation is a little different. Applications often have built-in memory management tools that work more competently than Android system settings. For example, Telegram can set up automatic cache cleaning of media files so that they do not take up space at all. Go to the settings of the messenger itself, select Data and memory, and find Memory Use. There you can safely delete the cache without fear of losing correspondence, since they are stored on the server.
If the app continues to work slowly after cleaning the cache, try updating it through the Google Play store or GetApps. Often developers release patches that optimize memory consumption. In rare cases, a complete reinstallation of the program helps, but before doing this, make sure that your data is stored or synced with the cloud.
Deep Clean Up Through Developer Menu and Recovery
For advanced users who want to maximize performance, there are deeper cleaning methods, one of which is using the Recovery menu, which is a special boot mode that allows you to perform system operations regardless of the main operating system, you can get there by turning off your phone and holding a combination of buttons (usually Volume Up + Power), but you should only do this if you are confident in your actions.
In the Recovery menu (often TWRP or stock MIUI menu), you can find Wipe Cache Partition. This command clears the system cache that is not available through normal settings. This is useful after a firmware update, when old temporary files can conflict with a new version of Android. However, for the average user, this procedure can be redundant and even risky if handled carelessly.
| Cleaning method | Level of difficulty | Security of data | Efficiency |
|---|---|---|---|
| Annex "Security" | Low. | Safe. | Medium |
| Application settings | Low. | Safe (when selecting "Cash") | High (point) |
| Recovery menu | High-pitched | It is safe (unless you confuse it with Wipe Data) | Maximum |
| Third-party utilities | Medium. | Requires the trust of the developer | Medium |
There is also a hidden developer menu that you can access by clicking on the MIUI version number several times in the About Phone section, where you can find options to limit background processes, which indirectly affects the rate of cache accumulation. However, changing the settings in the developer menu without understanding their purpose can lead to unstable system operation, so novice users should refrain from experimenting in this section.
⚠️ Warning: In the Recovery menu, never select "Wipe Data" or "Factory Reset" if you want to save your photos and contacts. These commands will completely destroy all data on the device".
Cleaning automation and third-party utilities
Modern Xiaomi smartphones allow you to set up automatic cleaning, which eliminates the need to do it manually. There is a "Auto Clean" feature in the Security app that can be activated. It will periodically check the device for garbage files and delete them when the phone is in standby mode. This is a great way to keep order in the background without being distracted from using the gadget.
As for third-party applications like CCleaner, Clean Master or SD Maid, there are split opinions, on the one hand, they offer more flexible settings and deep analysis of the file system; on the other hand, they consume resources, show ads and sometimes can be too aggressive. Owners of Redmi with the shell MIUI 12/13/14 and later often do not need third-party software at all, because the built-in tools work quite efficiently.
If you do decide to install a third-party cleaner, only choose proven high-ranking solutions on Google Play. Avoid apps that promise to "speed up the Internet" or "cool down the processor" are often marketing tricks. A good utility should just show what takes up space and let you safely remove it. Remember that installing redundant apps by itself increases the load on the system.
You can also use built-in scenarios in the Security app to automate, for example, you can set up a rule that says, "If there's less than 1 GB of free space, run a cleanup." This will prevent the phone from suddenly stopping receiving messages or taking photos because of overcrowded memory, a preventive approach that is much more effective than dealing with the consequences of space shortage.
Frequent errors in cleaning Xiaomi memory
Despite the simplicity of the procedure, users often make errors that can lead to loss of important data or disruption of the system. One of the most common mistakes is to delete the.thumbnails folder or system directories through the file manager manually. The system automatically recreates them, but in the process there may be a conflict of access rights, which will lead to errors in the gallery or the camera will not be able to save the picture.
Another mistake is overzealousness. Some users run cache cleanups five times a day. It doesn't make sense, because apps will still need to re-download temporary files, which will increase traffic consumption and battery power. The cache is designed to speed up work, and its complete absence makes the processor and modem work harder. The optimal balance is cleanliness without fanaticism.
Also be careful about clearing messenger data. Many people confuse cleaning up the media cache with cleaning the message database. If WhatsApp or Viber clicks Clear All Data in Android settings, you will lose all your correspondence history if you don't make a backup. Always check what type of data you're going to delete.
💡
The main mistake of users is to manually delete system files or completely clean the data instead of the cache, which leads to the loss of personal information.
Memory Filling Prevention and Optimization
To avoid overloading too often, you should change your smartphone habits, first of all, set up cloud sync for photos and videos. Services like Google Photos or Mi Cloud can automatically delete images from a device after they are uploaded to the cloud, freeing up gigabytes of space, especially for Redmi models with a small amount of internal memory (32 or 64 GB).
The second important aspect is to monitor installed applications: periodically review the list of programs and delete those that you have not used for more than three months. Many applications continue to work in the background and accumulate cache even if you do not use them, and it is also worth turning off auto-update applications over the mobile network, so as not to accidentally jam memory with heavy game updates.
Regularly restarting your smartphone is another simple but effective prevention method: Rebooting cleans your RAM and ends the hanging processes that can block normal operation of the system. Just do this once a week to make your Xiaomi work like new. Don't ignore system updates, as they often contain memory optimizations.
