Modern smartphones, even budget models like the Redmi 7A, are slowing down over time, a natural process of accumulating temporary files, app cache and residual data after remote programs, and if your Xiaomi has become noticeably slow and memory space has become critically reduced, it's time to do a cleanup.
There are several levels of cleanup, from securely deleting temporary files to radical resets to factory settings. The choice of the specific method depends on how severe the performance problems are and whether you plan to save personal data. In this article, we will look at all the available ways to help return your device to its previous speed.
Owners of Xiaomi Redmi 7A often face a shortage of internal memory, as the basic versions are equipped with only 16 or 32 GB of space. Proper cleaning of the system allows you to free up gigabytes of space, which is especially important for installing updates or new applications. Let's consider where to start servicing your gadget.
Clearing cache and temporary files through settings
The safest and first step to optimisation is to use the built-in tools of the MIUI system. Xiaomi’s operating shell has a powerful built-in mechanism for maintenance that does not require installing third-party software. First, you need to go to the Settings → Memory menu or use the Security application, which is preinstalled on each device.
Here you'll see detailed statistics of storage usage, and the system will suggest removing the "junk" that's taking up space, usually leftover installation files, image sketches, and application logs, and clicking "Clean" will trigger the process of removing temporary data, which often solves the problem of space scarcity.
But be careful: some apps cache important information for fast loading, such as navigation maps or streaming services that can take a little longer to load after cleaning up on their first run, a normal behavior that is compensated for by freed space.
💡
Use the Deep Clean feature in the Security app once a week to remove duplicate photos and old WhatsApp files, which often take up gigabytes.
Special attention should be paid to the "Applications" section, which includes those that you have not used in a long time, and removing such programs is the most effective way to free up space, and remember that even after deleting the application can leave its folders at the root of internal memory, which must be manually deleted through the file manager.
Using Developer Mode to Clean Memory
For more advanced users of Xiaomi Redmi 7A, the developer mode is available, which allows you to manage processes in more detail. To activate it, you need to quickly click seven times on the build number in the About Phone section, and then a new option will appear in the settings menu for developers.
In this section, you can find the option "Do not remain active." If you turn it on, the system will force applications to unload from RAM immediately after they leave, which can significantly speed up the operation of a device with a small amount of RAM, but will cause applications to start from scratch every time they open, consuming more battery power.
Background Process Limit is also available here, so you can limit the number of applications running simultaneously in the background. For the Redmi 7A, the best choice is to limit 2 or 3 processes, which will prevent RAM overflow and reduce the load on the processor.
Should I turn on the debugging on USB?
It's important to understand that tampering with system settings requires caution, changing animation settings or interface scale can make it uncomfortable to manage, and if you're not sure what the specific option is, you'd better leave the default value.
Full reset to factory settings (Hard Reset)
If the software cleaning doesn’t work and the smartphone continues to work unstable, the only way out is a complete reset.This procedure will return the Xiaomi Redmi 7A to the “out of the box” state by removing all user data, accounts and applications.Be sure to back up important contacts and photos before you start.
There are two ways to reset. The first is through the settings menu. Go to Settings → Advanced Settings → Restore and Reset. Select Reset and confirm the action. The phone will restart and start the cleaning process, which can take anywhere from 5 to 15 minutes.
The second is if the phone is not turning on or locked, and you need to go into Recovery mode, turn the device off completely, then press the power and volume buttons at the same time, hold them until the Mi logo appears, and then release them.
☑️ Checklist before reset
In the Recovery menu, you can navigate with volume buttons and select with a power button. Select the language (usually English), then the Wipe Data option, and confirm the action of Wipe All Data. Once you have finished, select Reboot to restart.
⚠️ Note: After resetting on new versions MIUI You might need to enter a password from a Mi Account that was previously linked to the device, and it's a theft protection, and it's almost impossible to get around it without a password.
Cleaning Memory Through Computer and ADB
For those who want to clean up the system debris as deeply as possible, which is not visible to the average user, a method using a computer and debugging over USB is suitable. This method requires prior preparation and the presence of a PC with Xiaomi drivers installed and ADB platform tools.
First, you need to activate USB debugging in the developer menu mentioned above. Connect your phone to your computer with a cable and allow debugging on your smartphone screen. Then on your PC, open the command line in the ADB tool folder.
To remove system applications that are not needed and take up space (bloatware), you can use commands such as:
adb shell pm uninstall -k --user 0 com.example.appHere, com.example.app is replaced with the name of the application packet being removed, which allows you to free up a significant amount of space in the system partition where the average user does not have access, but beware: removing critical system components can lead to an interface failure.
💡
Using ADB allows you to remove pre-installed garbage that can not be removed by standard means, freeing up to 1-2 GB of system memory.
You can also manually analyze the file system through your computer, plug your phone in file transfer mode (MTP) and check the Android/data and Android/obb folders. Often, remote games and programs that weigh hundreds of megabytes are left behind.
Fighting viruses and advertising software
Malware can be one of the reasons for the Redmi 7A’s slowdown, often disguised as useful utilities, flashlights or memory cleaners, and signs of infection include pop-up ads on the desktop, fast battery drains, and spontaneous installation of applications.
To check the device, use the built-in antivirus in the Security app, which uses Avast or Tencent databases. Run a full scan. If the built-in tool does not find threats, but suspicions remain, you can install a proven third-party antivirus, such as Malwarebytes or Dr.Web, check and immediately remove it.
Often, ad viruses are hidden in a list of apps without an icon. To find them, go to Settings → Apps → All Apps. Carefully review the list. If you see an app without a name or with a transparent icon, delete it immediately.
| Type of threat | Symptoms | Deleting method |
|---|---|---|
| Advertising virus | Pop-up windows on the desktop | Removal through application settings |
| Miner | Strong heat, quick discharge. | Safe mode + antivirus |
| Spyware | Strange SMS, camera access | Full reset (Hard Reset) |
| Trojan | Screen lock, demand for money | Reset via Recovery |
If you can’t remove a malicious application in the usual way (the “Delete” button is inactive), then the virus has received administrator rights. Go to Settings → Advanced Settings → Privacy → Device administrators and uncheck the suspicious application.
Optimizing the work after cleaning
Once you have cleaned the Xiaomi Redmi 7A of debris or made a complete reset, it is important to properly configure the system to prevent future problems.Do not install dubious applications from unknown sources.Try to download software only from the official Google Play store or GetApps.
Update your operating system regularly. Xiaomi engineers are constantly releasing patches that fix memory optimization errors. You can check for updates in the Settings → About phone menu. Also keep an eye out for updates to the apps themselves, as new versions often contain bug fixes.
Use widgets and live wallpaper with caution. They consume CPU and RAM resources, which is for a budget Redmi. 7A It's better to use static, dark wallpaper, which also saves battery life. AMOLED-screens (although in this model the screen is IPS, The dark topic still reduces the load on the system).
⚠️ Warning: Do not use third-party accelerators and cleaners from the Play Market. They are often the source of advertising and only create the appearance of work, constantly hanging in the background and using resources.
Periodic smartphone reboot is a useful habit: just turn off and turn on the phone every 2-3 days, so that the system resets accumulated errors in memory and completes the hanging processes, this is a simple procedure that prolongs the life of the device.
💡
Enable the memory extension feature (if available in your version of MIUI) to use part of the internal storage as virtual RAM. This can help when working with heavy applications.
