Xiaomi and Redmi are known for their high performance, but even the powerful hardware eventually begins to experience problems with processing. It is an inevitable process of accumulation of digital debris that slows down the system and causes irritation to the owner. The question of how to clean the shaomi becomes relevant when the device begins to open applications for a long time or spontaneously close them.
There are two fundamentally different approaches to solving this problem: software cleaning of internal memory and physical cleaning of the case from contamination. Ignoring the first aspect leads to overflow of storage, and neglecting the second to overheat the processor and fail speakers. In this article, we will discuss both directions in detail to make your gadget work again as new.
It is important to understand that standard MIUI or HyperOS tools do not always cope with the deep debris left over from remote applications. In addition, physical cleaning of charging ports requires special care to avoid damaging contacts. We will consider safe methods that do not require disassembly of the device or special skills.
Memory Occupancy Analysis and Hidden Files Search
Before you run any cleaning tools, you need to understand what exactly takes up space. Often users do not realize that the bulk of data is cached videos from messengers or forgotten screenshots. Android has a complex folder structure, where gigabytes of useless information can lie in the depths.
To start, you can go to the standard Security app, which is pre-installed on all Xiaomi devices, which gives a primary assessment of the system's state, but often only shows the tip of the iceberg. A deeper analysis can be done through the storage settings, which visually displays the distribution of space between applications, images and system files.
Telegram and WhatsApp have a habit of storing all the media files you have viewed in your device’s memory, even if you’ve already deleted them from chat, creating a “digital obesity” effect where formally empty space quickly disappears.
Use the built-in analyzer to find files larger than 100 MB. Often there are forgotten recordings of the recorder or video, shot in high resolution 4K. Removing such "heavyweights" instantly frees up a significant amount of space.
Cleaning the cache and removing system debris
Cache is temporary data that apps save to make things faster, and over time, these files can become corrupted or redundant, leading to bugs in the software, and cache cleaning is a secure procedure that doesn't delete your logins, passwords, or personal communications.
To perform deep cleaning, it is recommended to use the built-in Cleanup utility, which scans the system for residual files, APK-However, for more advanced users, deep cleaning mode is available through the developer menu or third-party file managers with access rights.
⚠️ Note: Do not delete files from system folders Android/data or Android/obb manually, if you are not sure of their purpose, this can lead to incorrect operation of games and applications that require re-loading resources.
Special attention should be paid to cleaning the DNS cache and Google system services, which can be done through the recovery menu or special commands, but for the average user, standard tools are enough, and regular prevention once a month will help keep the system in good shape.
☑️ Checklist of digital hygiene
After cleaning, restart the device, so that the system can reset the file index and correctly display the space that has been vacant, and sometimes the memory counter is only updated after a full cycle of shutdown and on.
Removing duplicates and optimizing media files
The media library is the largest storage in any modern smartphone, and over the years, thousands of images have been accumulated in the gallery, including many similar or completely identical frames, and duplicates can occur when synchronized with the cloud or accidentally resave.
The newer versions of MIUI and HyperOS have a built-in search function for similar photos, which uses artificial intelligence algorithms to group together images taken at the same time, allowing you to quickly select the best shot and delete the rest, making room without losing any important moments.
It's also worth checking the folder "Recently deleted." The files you delete don't disappear immediately, but are stored there for 30 days, continuing to take up space. Cleaning this folder is the fastest way to get free space right now.
💡
Use Google Photos or Yandex.Disk with the function “Saving space” to compress the original photos in the cloud, leaving only thumbnails on the device.
For video files, the situation is even more critical: one minute high-quality video can weigh more than a thousand documents, revisit your video archives and delete unsuccessful or irrelevant recordings, if the video is important, it is better to transfer it to a computer or an external hard drive.
Physical cleaning of the hull and ports
The appearance of a smartphone affects not only aesthetics, but also functionality. A dusty USB-C charging port can cause poor contact, which will cause the phone to charge for a long time or stop responding to the cable. Speakers clogged with dirt begin to sound quieter and hoarse.
To clean the exterior, you will need a minimal set of tools: soft microfibre, isopropyl alcohol (not pure, but in the form of special wipes), and a wooden toothpick. The use of metal objects such as needles or pins is strictly prohibited, as they easily damage contacts inside the port.
Wipe the screen and back with a microfiber. If the contamination is severe, moisten the fabric slightly with a screen cleaner, but never spray liquid directly on the phone. Water can leak under the display frame and cause the board to corrosion.
| Element | What to clean | What to avoid |
|---|---|---|
| Screen. | Microfiber, special spray. | Acetone, alcohol, paper wipes |
| Charging port | Wood toothpick, compressed air | Metal needles, liquid |
| Dynamics | Soft brush, scotch. | Sharp objects, powerful vacuum cleaner |
| Camera. | Dry microfiber | Dirty tissue, finger. |
To clean the speaker's mesh, use a soft toothbrush or paint tape. Gently stick a piece of tape with a sticky side to the dynamik and pull back sharply - this will pull the dust out of the depths. Repeat the procedure several times for better effect.
Cleaning dynamics from water and dust
Even if your Xiaomi has IP53 or IP68 moisture protection, the speakers are still a vulnerability, and getting water inside the grid causes sound distortion and, at worst, short circuits. There is a software method of pushing water out with sound waves.
You can find special low-frequency hum audio files on the Internet that make the speaker's membrane vibrate at a high amplitude, and turning it on at full volume helps knock water droplets out, but this method is only effective for fresh moisture.
⚠️ Warning: If the phone falls into water, don't try to dry it with a hair dryer or put it on the battery.High temperatures can melt the glue holding the screen and damage the battery.
Dust accumulates gradually in the speakers, regular soft brushing will prevent the formation of a dense layer of dirt that is difficult to remove, if the sound has become completely quiet, you may need professional ultrasound cleaning at the service center.
The rice myth
Remember that software "water pushers" will not help if moisture gets deep inside the case, in such cases it is better not to take risks and consult specialists for opening and cleaning the board.
Resetting settings as a last resort
If the software cleaning doesn't work and the phone keeps slowing, the radical but effective method is a complete factory reset, which removes all data, applications and settings, returning the device to the "out of the box" state.
Before performing a reset, be sure to back up your important data. You can use the Mi Cloud cloud, Google Drive, or the built-in Backup app to save contacts, SMS, and a list of installed applications to an external medium or computer.
To perform the reset, go to Settings → About Phone → Reset. The system will warn you that all data will be deleted. Confirm the action and wait for the process to be completed, which can take from 5 to 15 minutes depending on the amount of memory.
💡
Hard Reset is the only way to ensure that viruses are removed and that deep system errors that are not treated with routine cleaning are corrected.
Once reset, the phone will work as quickly as possible, but during use, try not to install questionable applications and regularly carry out preventive cleaning so that the problem does not return after six months.
