Xiaomi’s Redmi series has a reputation for reliability, but even the most stable Android operating system requires maintenance over time. Redmi 4X owners often face slowdowns, lack of space, or the need to delete personal data before selling a gadget. Proper cleaning of the device can literally breathe a second life into it, returning the speed of the first days of use.
The process of putting a smartphone in order can range from simple deletion of temporary files to radical reset to factory settings. The choice of method depends on how severe the performance problems are and what the end goal of the user is. In this article, we will take a detailed look at all the available methods so that you can choose the most suitable for your situation.
Regular maintenance is not to be ignored, as the accumulation of digital debris affects the speed of writing and reading internal memory data. System logs, application cache and remnants of remote programs can take up gigabytes of space critical to the operation of MIUI. Let's look at step-by-step instructions that will help you effectively manage the resources of your device.
Preparation of the device for deep cleaning
Before taking active action to delete data, a number of preparatory steps must be taken, a critical step, as some cleaning methods involve the complete destruction of user information, and ignoring the preparation can lead to the irretrievable loss of important contacts, photos and documents.
First of all, make sure that the battery charge is at least 50-60%. The cleaning process, especially a complete reset, can take time, and a sudden power outage in the middle of the procedure can damage the file system. SIM-card to avoid accidental formatting of external media or resetting of operator settings.
Make sure to back up all your important data. You can use Mi Cloud cloud service or sync with your Google account to save contacts and calendar. Photos and videos are best copied to your computer or external hard drive manually.
☑️ Checklist before reset
Another important nuance is remembering the passwords from your Mi Account and Google account. Once you reset, Android security will request authorization from accounts that were previously associated with the device. If you forget the login details, it will be extremely difficult to unlock your smartphone, and in some cases impossible without contacting the service center with a check for purchase.
Clearing cache and temporary files through settings
The safest and easiest way to free up space is to use the built-in MIUI system tools. Xiaomi’s operating shell features a powerful built-in optimizer that allows you to remove garbage without risking system files. This method is ideal for regular maintenance and does not require root rights.
To start, open the standard Security app, which usually has a green shield icon. From the menu, select Cleanup. The system will automatically scan the device for temporary files, cache, residual files of remote applications and advertising debris. After you complete the scan, click Clean to remove the objects found.
💡
Clean the cache regularly through the built-in Security app once a week to prevent garbage accumulation and keep the interface running fast.
In addition to cleaning up quickly, you should also pay attention to managing applications. Go to Settings, then select the Apps section and go to the All Apps tab, and you can find heavy programs like social media or instant messengers that often accumulate a huge amount of cached data.
- 📱 Select a specific app from the list, such as Viber or Telegram.
- 🗑️ Click on the Clear button and select Clear cache (not to be confused with Clear Everything if you want to save correspondence).
- 📉 Check the volume of vacated space in the status bar.
- 🔄 Repeat the procedure for all resource-intensive applications.
This approach allows for spot removal of debris without affecting personal settings and user data, but if the system is slow even after cleaning the cache, you may need to do more in-depth intervention in the file structure or reset settings.
Using Recovery Mode for Resetting
Recovery Mode is a special diagnostic interface built into the firmware of the smartphone at a low level, it allows you to perform system operations regardless of the state of the main operating system, this mode is necessary if the phone does not boot, freezes on the logo or if you want to perform the cleanest reset without the intervention of third-party software.
To enter Recovery mode on Redmi 4X, you need to turn the device off completely. Then press the Volume Up and Power button at the same time. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume button until the main menu appears.
⚠️ Attention: In the Recovery menu, the touch screen is not working. Navigation is done with volume buttons (up/down), and the choice of item is confirmed by the power button.
From the menu that opens, select the language (usually English and Chinese only, choose English). Next, look for Wipe & Reset or Wipe Data. You will be offered two options: Wipe All Data (full reset) and Reset Password (password reset).
The system will request confirmation of action, because this process is irreversible. Choose Confirm and wait for the process to be completed. Once the cleanup is successful, select Back to Main Menu, and then Reboot -> Reboot to System. The first run after a reset may take longer than usual - that's OK, the systems go.
What if Recovery is not included?
Full reset via the system settings menu
If the operating system is stable and you can get into the menu, the most convenient way to clean up the Xiaomi Redmi 4X is to use the regular reset function.This method is less risky for beginners, since the interface is fully translated into Russian and provided with hints.
Follow the path: Settings -> Advanced Settings -> Recover and Reset. Here you will be greeted with a warning that all data will be deleted. Before pressing the Reset button, check again if you have backed up important files.
The system will offer several reset options. You can choose to clean only system settings or completely remove all content. To prepare the phone for sale or transfer to another person, be sure to choose the option to erase everything.
| Parameter | Description of action | Impact on data |
|---|---|---|
| Resetting settings | Return of system parameters to factory | Photos and contacts are still available |
| Erase everything | Full formatting of internal memory | All files and accounts are deleted |
| Reset via Recovery | Hardware button reset | Complete deletion of data |
Once confirmed, the phone will restart and the formatting process will begin, the progress indicator will show the execution rate, do not interrupt this process and do not try to turn off the device, even if it seems to be hanging, at which time the critical re-marking of memory parts takes place.
Removal of system debris and residual files
Even after a standard cleaning, the system can still have so-called “tails” – folders and files that are created by applications but are not deleted after they are uninstalled. 4X You can use a built-in conductor or third-party utilities.
Open Explorer and go to the root folder of internal memory. Notice the folders with the names of remote applications or games. Often at the root are folders BaiduNetdisk, Tencent or UCDownloads, which can grow to gigabytes.
Be careful when deleting files manually. Never delete.apk files from system folders unless you are sure of their origin, and do not touch folders with system process names. Mistakeful deletion of a system file can lead to a cyclic bootloop.
- 📂 Search for folders with names of remote games and social networks.
- 🗑️ Delete the contents of the Cache and Temp folders if they are in the user section.
- 📸 Check the folder. DCIM/.thumbnails — There are miniatures of photos that can take up a lot of space.
- 📥 Clean Download folder from old app installers.
For a deeper analysis, you can use the storage analyzer feature in memory settings, which visualizes the space and shows which files occupy the most space, and helps you find forgotten videos or duplicate documents that you don't need.
Cleaning up viruses and malware
While Android is considered a fairly secure system, Redmi 4X is not immune to the penetration of ad viruses and Trojans, especially if you install applications from unverified sources.
The built-in antivirus in the Security app uses databases from Avast and AVL. Run a scan through this application. If the virus is on the list of known threats, the system will prompt it to be removed or neutralized.
⚠️ Warning: If a virus blocks the entrance to settings or menus, try to start the phone in Safe Mode. To do this, when you turn on when the Mi logo appears, press the volume down button.
Only system applications are downloaded in Safe Mode, find a suspicious app (often without an icon or name) in the installed program list, and delete it through the app menu.
If standard methods do not help, the only way out is a complete reset via Recovery, described above.This is guaranteed to remove any software debris, as the partition with user data will be completely reformatted. After reset, it is recommended to change the passwords from important accounts, since some Trojans can steal the entered information.
💡
Recovery is the only 100% guaranteed way to remove complex viruses that lurk in system processes.
