How to Clean Cache on Xiaomi 7A: The Complete Guide

Xiaomi 7A series smartphones, despite their popularity, are beginning to experience a shortage of RAM and internal memory over time, an inevitable process associated with the accumulation of temporary files created by the MIUI operating system and installed applications to speed up work. If you notice that the device has become slower and space shortage notifications appear more often, then it’s time to do maintenance.

Users often confuse the concepts of cache and application data. It is important to understand that cache cleaning is a secure procedure that only deletes temporary files without affecting your personal photos, contacts or passwords. Unlike a complete reset, this operation does not require long preparation and can be carried out regularly.

In this guide, we’ll look at all the available ways to free up space on your Xiaomi.We’ll break down the system’s regular tools, hidden engineering menus, and third-party utilities so you can choose the most suitable option for your situation.

Why you need to clean the cache on the Xiaomi smartphone

The Android operating system that underpins MIUI is using caching to quickly load frequently used items. Apps save pictures, scripts and thumbnails to keep them from re-uploading from the Internet. However, over time, this “useful” layer becomes digital junk, which takes up gigabytes of usable space.

Regular cleaning allows not only to free up space, but also to correct errors in the operation of programs. For example, if Instagram or Telegram stopped correctly displaying new images, the problem often lies in corrupted temporary files.

⚠️ Warning: Clearing the cache does not delete the correspondence history or saved logins, but cleaning the application’s Data will completely reset it to factory.

In addition, overcrowded cache can cause the processor to overheat, as the system has to index huge amounts of unnecessary information.The optimal interval for preventive cleaning on the Xiaomi 7A is once every two weeks when used actively.

There are several levels of cleaning, from surface debris removal to deep cleaning of system partitions, and understanding the difference between them will help avoid accidental loss of important information.

Cleaning the cache through the standard “Security” application

The easiest and safest way for the average user is to use a built-in tool from Xiaomi.Security is already preinstalled in the system and has access to all the necessary memory partitions.

To get started, look for an icon on your desktop called Security or Security and run it. From the menu that opens, select Clearer, and the system will automatically scan and show you the amount of files that can be deleted without risking stability.

Once the analysis is complete, click the Clean button.The process will take a few seconds. It is important to note that this method only removes surface debris and does not affect the cache of specific heavy applications such as YouTube or browsers.

For more detailed work, go to the Memory section inside the app, and here you'll see a list of the apps that take up the most space, and if you click on a specific program, you can choose whether to delete the cache or all the data.

Deep cleaning of the cache of specific applications

If a standard cleaning fails, manually check the heavyweights. Most often, instant messengers, social networks and video services occupy the most space. Go to the Settings menu → Apps → All applications.

In the list, find the program you want, like Viber or TikTok, and click on it to open the management page, and you're interested in the memory or storage button.

Why is the cache growing so fast?
Messengers store every photo and video you see in cache, and if you're in dozens of groups and channels, you can accumulate up to 5-10 GB of garbage in a month, which is formally a cache, but in fact, an archive of the content you've viewed.

Click the Clear Cache button. Be careful: there is a Clear Everything (or Reset) button next to it, which will delete all settings and authorizations in the app. Use it only if you want to completely reinstall the program without deleting it. APK-file.

The Chrome or Mi Browser browser can grow to several gigabytes if you watch videos online often, and cleanup is safe, but may require re-entering passwords on some sites.

Using the Developer Mode to Clean

The Xiaomi 7A has additional memory management capabilities available through the developer menu, which allows you to force processes to stop and clear the clipboard more efficiently than standard means.

First, activate Developer Mode. Go to Settings → About Phone and quickly click 7-10 times on MIUI Version. Once you have become a developer, go back to the main settings menu.

Go to the "Advanced" (or "Advanced Settings") section and select "Developers" and find "Background Process Limit" and set the "No Background Processes" value for the cleaning time, then return "Standard Limit."

There is also a Do Not Save Action option on this menu, which if activated, will not store the state of closed applications, which will free up RAM, but may slow down the switching between tasks.

Use this method requires caution: Do not disable system services unless you are sure of their purpose, as this can lead to unstable operation of the MIUI interface.

Cleaning Hidden System Garbage and DCIM Folder

Often, users forget that the gallery and camera also create cache. The DCIM folder can contain a.thumbnails folder that stores thumbnails of every photo ever taken. On older models like the Xiaomi 7A, this folder can weigh several gigabytes.

To access these files, use a file manager, such as Explorer or Total Commander. Enable the display of hidden files in the Explorer settings (usually a tick on the menu).

Find the MIUI → gallery → cloud → cache folder, and it stores cloud thumbnails, and you can delete them if you're not syncing with the cloud right now.

⚠️ Note: Deleting the folder.thumbnails will lead to the fact that the next time you open the gallery, the system will regenerate thumbnails, which can temporarily load the processor.

Also check the Android → data folder. Here some apps (like maps or games) store their cached data. Only delete the contents of folders that match the names of games already deleted.

💡

Use the Deep Clean feature in the Security app once a month to find duplicate photos and large files that are forgotten in downloads.

Automation of cleaning with scripts and third-party software

For advanced users, there is the possibility of automating the process, and applications like SD Maid or Files by Google can run in the background and warn about the accumulation of garbage.

However, Xiaomi’s built-in tools often work more aggressively than third-party counterparts, as they have system rights. Third-party programs may not have access to system partitions due to the limitations of Android versions 10 and above.

If you use root rights, you can use scripts to clean Dalwick's cache and art cache, and that requires you to set up the terminal and know the commands, but it gives you the best results.

For the average user, set up an automatic cleaning in the Security app. Go to the cleaner settings and turn on the Auto Clean option by selecting a memory filling threshold, such as 80%.

Frequent questions and problems with cleaning

While maintaining the Xiaomi 7A, users often face the same questions, and the following are the answers to the most popular ones to help avoid common mistakes.

There's a lot of speculation that when you clean the phone, it's going to get worse, and in fact, it might take a little longer to start the app first or start it after you clear the cache, because the system needs to recreate temporary files. That's okay.

💡

Regularly cleaning the cache extends the life of the built-in drive, preventing it from wearing out from constant cycles of overwriting temporary files.

If the application crashes or doesn't work properly after cleaning the cache, try to clear not only the cache, but also the data (pre-saving important information), which will return the program to its original state.

Can I remove the cache of system applications?
Deleting the cache of system applications (e.g., Phone, Contacts, System UI) is possible, but you need to do it with caution.It won’t delete your contacts or calls, but it can reset the design settings or order of the ikon on the desktop.
Why didn't the place clear after the cleanup?
You may have cleaned only the cache, but you didn't delete the files in the Downloads or Recycle Bin folder of the gallery, and the junk files could immediately re-accumulate if many background applications were open.
Is it bad for Xiaomi 7A to keep 90% of its memory free?
No, it's even useful. MIUI is optimized to work with a filled storage, but having 10-15% free memory guarantees speed and no brakes when installing updates.
How to clean the DNS cache on Xiaomi?
To do this, go to the Wi-Fi settings, click on your network and select "Change." In the advanced settings, change the DNS to "Static" and enter 8.8.8.8, then return back to "Automatically." This will reset the DNS cache.
