How to Clean Cache on Xiaomi Redmi Note 7: The Complete Guide

The Redmi Note 7 has become one of Xiaomi’s best-selling smartphones, offering great camera and performance at an affordable price. However, over time, even the most powerful device starts to run slower and memory space disappears rapidly. The main reason for this phenomenon is often the accumulation of temporary files, the so-called cache that is created by the MIUI operating system and installed applications.

Cleaning up this data is not just a way to free up a few gigabytes, but it's also an effective way to fix bugs in software. Many users mistakenly believe that deleting the cache can damage personal photos or contacts, but it's not. Understanding the difference between system debris and important information will allow you to safely maintain the Redmi Note 7, extending its active life.

In this article, we will take a look at all the cleaning techniques available, from standard MIUI shell tools to advanced tools for power users, learn to distinguish between temporary file types and understand when intervention is really needed and when the system is coping itself.

What is cache and why delete it on Redmi Note 7

Cache is a buffer memory that stores temporary data to quickly access frequently used resources. When you open an application or visit a web page, Android stores some information so that the next time you start it, it loads instantly. On the Redmi Note 7, this mechanism works effectively, but over time, the size of such files can grow to inadequate values, taking up precious space.

The problem arises when the cache becomes too large or corrupted by software failures. Instead of speeding up, it starts to slow down the system, cause freezes or forced closure of applications. Regular cleaning helps restore the factory response rate of the interface and prevents conflicts between updated versions of programs and old temporary files.

It's worth noting that there are different types of cache: system, user, and Dalvik/ART. Deleting each has its own peculiarities and consequences. If you delete the cache of a particular app, such as YouTube or Telegram, you will have to log in again, but the correspondence and subscriptions will remain, which is an important nuance to consider before starting the procedure.

⚠️ Cache Clearing does not delete your personal files, but may require re-entering some apps accounts.

Periodically check the Storage section in the settings to see which apps take up the most space.

Use of the built-in "Security" application

The easiest and safest way to clean up the Redmi Note 7 is to use Xiaomi’s regular tool, which is already pre-installed and optimized specifically for the MIUI shell, which scans the device for temporary files, remnants of remote programs and advertising debris.

To start the process, you just need to open a green icon with a shield on your desktop. After an automatic scan, the system will prompt you to click the "Clean" button. This method only deletes secure temporary files without affecting your personal information. Regular use of this feature helps keep the system on top without risking damaging important data.

Inside the app, you can also access the Cleanup section, where you can configure scan settings in more detail. You can choose to delete large files, duplicate photos or unused applications. The Redmi Note 7 has a fairly powerful processor, so the scan is quick, usually taking no more than 30 seconds.

It is important to understand that the built-in cleaner does not always find the cache of all third-party applications, especially if they hide their temporary files deep in the system. Therefore, to completely clean up, you may need to use additional methods, which we will discuss below.

Clearing the cache of individual applications through settings

If a particular program is not working properly or takes up too much space, it makes sense to clear its cache individually, which allows you to pinpoint the problem areas of the Android system. On the Redmi Note 7, this is done through the settings menu, which gives you complete control over the process.

You need to go to the Settings menu. → Annexes → All applications. In the list that opens, select the desired program, such as a browser or social network. In the app menu, you will see a button to Clean or Clear data, where you can select the option to Clear cache. This action is safe and will not delete your logins or save.

Special attention should be paid to messengers like WhatsApp or Viber, which can accumulate gigabytes of media files in the cache. Clearing the cache here will free up space, but will not delete the history of correspondence if it is stored on the server or in the database. However, be careful not to confuse the “Clear cache” button with the “Erase all data” button, since the second action will return the application to the state immediately after installation.

Deep cleaning through the Recovery Engineering Menu

For more advanced users who want to do a deep cleaning, there is Recovery mode, which removes the system cache that is not available through the usual settings menu. On the Redmi Note 7, this mode is entered when the phone is turned off by pressing the combination of volume and power buttons.

Once you log into the Recovery menu (usually the Mi logo with tools or the TWRP/Stock Recovery text menu), you need to find the Wipe Cache Partition. Using volume button navigation and power button confirmation will allow you to select this option. The process takes a few minutes and is completely secure for personal data, since it only affects the system partition of temporary files.

This method is especially useful after major firmware updates to MIUI, when old system files may conflict with new ones. If the phone starts to run slowly or quickly after the upgrade, cleaning the cache partition in Recovery often solves the problem, but do not do it too often, since the system takes time to re-accumulate the necessary temporary data.

⚠️ Note: Select items carefully from the Recovery menu. The option “Wipe Data” or “Factory Reset” will delete all your files without the possibility of recovery.

Cleaning DNS cache and browsers

The cache deserves special attention. DNS, The one who is responsible for comparing domain names with IP-Over time, in the table. DNS Redmi Note 7 can accumulate erroneous entries, which causes some sites to stop opening or load for a long time.

For cleaning. DNS You can use a hidden menu of engineering tests. You can type in the code ##4636## to go to the testing menu. MIUI, discharge DNS. An alternative and simpler way is to turn on and off flight mode, which will forcibly reconnect the network and update it. DNS-record.

Browsers also accumulate a huge amount of data. In Chrome or the built-in Mi Browser, you need to go into history and select “Clear History.” It is recommended to tick the boxes opposite “Images and other files stored in cache” and “Cookies” that will free up space and correct site display errors, but require re-entering passwords on some resources.

💡

DNS cleanup is an effective way to solve connection problems to specific sites without requiring a router reboot.

Automation and third-party utilities

While Xiaomi’s built-in tools are quite effective, some users prefer third-party solutions for more flexible control. Apps like SD Maid or Files by Google can find remnants of remote programs and empty folders that the standard cleaner ignores. On the Redmi Note 7, such utilities work stably, but require careful attention to the permissions issued.

Automation allows you to set up a schedule cleaning, for example, you can set up a scenario where the browser cache is cleared every night, which requires the use of automated applications such as MacroDroid or Tasker, which helps keep the system clean without user intervention, but can slightly increase battery consumption in the background.

When installing third-party cleaners, it is important to be careful with advertising modules, which are often built into free versions. Some of them can, on the contrary, slow down the phone, constantly working in the background. The best strategy is to use 1-2 proven applications and not install many duplicate utilities “for acceleration”.

• 🧹 SD Maid is a powerful tool for finding dead files.
• ⚙️ Total Commander – file manager with duplicate search function.
