How to Clean Xiaomi Phone from Garbage by Hand: The Complete Guide

Xiaomi smartphones are famous for their performance, but even the most powerful models become slower over time, a phenomenon that is caused by the accumulation of digital junk: temporary files, residual data from remote applications and bloated system cache. Many users mistakenly rely solely on built-in automatic utilities, which often work superficially and do not affect deep system folders.

Manually cleaning the device frees up gigabytes of space that are hidden from the standard storage analyzer. This process requires care, as you get full access to the Android file structure. If you act carefully, you can significantly speed up the MIUI or HyperOS interface and extend the life of the drive, avoiding critical memory filling.

In this article, we will discuss proven deep cleaning methods that do not require third-party software installation or root rights. You will learn to distinguish between important system files and unnecessary digital ballast that is safe to delete. Proper maintenance of a smartphone is the key to its stable operation for many years.

Storage occupancy analysis and preparation

Before you start deleting files, you need to determine exactly what is taking up space. Standard system reports often group data incorrectly, mixing the cache of applications with personal documents. First, you should go to the settings menu and select About phone, and then Warehouse to see the detailed memory card.

Data visualization helps you understand the pattern of space consumption. You may find that most of the time is not photos, but messengers or cache streaming services. Android system files are tagged with appropriate tags, but their volume can be distorted due to the nature of the counting in the shell of the manufacturer.

It is important to understand the difference between user data and system cache: Deleting the former will lead to loss of information, while cleaning the latter will only reset the application settings to their initial state. Before starting any manipulation, it is recommended to back up important data in the Mi Cloud cloud service or on your computer.

• 📊 Open the settings and find the “Storage” section to assess the current state.
• 🗑️ Identify the largest categories of files (video, applications or documents).
• 💾 Backup important contacts and photos on external media.
• 🔋 Make sure that the battery is at least 30% during the procedure.

⚠️ Warning: Do not delete files from root system folders unless you are 100% sure of their purpose.

Cleaning cache and application data manually

The most effective way to free up space is to work with the cache of individual applications. Unlike a complete data cleanup, deleting the cache does not erase your logins and game progress, but eliminates temporary files, which often weigh gigabytes. To do this, go to Settings → Applications → All applications and select the desired program.

In the menu of a particular application, find the Clean button and select the “Clear Cache” option. If you select “Clean All”, the application will return to state immediately after installation, which will require re-authorization. Pay special attention to social networks and browsers, as they accumulate the most temporary garbage.

Some system services, such as Google Play Services or System UI, also have their own cache. Their cleaning can temporarily affect the operation of the interface, but often solves problems with freezes.

It's worth noting that regular cache cleaning is especially important for applications that you rarely use, which continue to run in the background and accumulate data, and periodic audits of installed programs help keep the system on track.

Working with the file system through a conductor

File Manager, which is built-in File Explorer, provides access to all folders on the device, and to see hidden system directories, you need to enable hidden files in the Explorer settings, which will allow you to access folders that are usually hidden from the user's eyes.

At the root of internal memory are often folders with names of applications that have been deleted long ago. They can contain error logs, temporary downloads or graphics residues. Deleting such orphaned directories is safe and returns precious megabytes. Look for folders with developer names or strange acronyms.

The Android/data folder is a special feature, which stores the cache files of games and heavy apps, and you need to be careful about removing the contents of this folder, which will reset the progress of games that do not support cloud-based saves, but will free up a lot of space.

Removal of residual files after uninstallation

When you delete an application in the standard way, it often has tails on the disk, which can be settings, saved profiles or downloaded media files. Use the Explorer analysis function to find them or manually check the folder. Android/data Directories with remote program names.

It's also worth checking the root of internal memory, and many apps create folders with names like com.company.app or just a brand name, and if you're sure that it's deleted, you can erase it, which is especially true for heavy gaming and graphics editors.

Don't forget the Tencent folder if you're using Chinese versions of apps or specific services, and it can contain gigabytes of images and videos from instant messengers that are duplicated in the gallery, and removing them will clear the space but disappear from the chat rooms.

• 🔍 Enable the display of hidden files in the Explorer settings.
• 📂 Check the root directory for remote application folders.
• 🗑️ Remove directories only of programs that are not in the list of installed programs.
• 📸 Clear duplicate media files in messenger folders.

⚠️ Note: Before deleting folders with unfamiliar names, type their name into a search engine. Some system services may have obscure names, and deleting them will disrupt the phone's operation.

💡

Use file extension search. Type in "log" or "tmp" to find and delete temporary files scattered throughout the device.

Cleaning the DCIM folder and thumbnails

The DCIM folder contains your photos and videos, but inside it is a hidden directory called.thumbnails, which stores thumbnails for quick display in the gallery, and over time, this cache can reach 5-10 GB, especially if you take a lot of high-resolution photos.

The removal of.thumbnails content is completely secure. The system will automatically create new thumbnails the next time a gallery opens. The only downside is that opening the album with a photo can take a little longer until the cache is re-formed.

Also in the DCIM folder are often folders from remote cameras or screenshots. Check for Screenshots and Edited folders. Sometimes there are unsuccessful frames or edited versions of photos, the originals of which have already been deleted and copies are forgotten.

Regular monitoring of this directory helps keep your memory in check, and if you're actively taking pictures, it's recommended that you check this folder once a month and clean it of technical debris.

Using the Developer Mode to Clean

Android has hidden capabilities for advanced users. By activating the developer mode (clicking 7 times on the build number in About Phone), you get access to additional tools. In the For Developers section, you can find the option to force services to stop, which sometimes helps to reset the hanging processes of garbage accumulation.

But the most useful tool here is the ability to debug over USB. By connecting your phone to your PC, you can use adb commands to deep-clean system partitions that a standard conductor can't get to, which requires a computer and an Android Debug Bridge installed.

The adb shell pm clear com.android.cache command (example, system-dependent) can clear the system cache more efficiently than the button in the interface, but it is only for advanced users who understand the command line structure to use this method.

adb shell pm trim-caches 999999999

This command is to free up space by removing the cache of all applications until the free space target is reached. Be careful: executing the command requires confirmations on the device screen.

💡

Developer mode is a powerful tool, but randomly changing the settings on this menu can disrupt your smartphone. Use only cleaning functions.

Prevention and automation of the process

So you don't have to manually clean your phone all the time, set up automatic processes. The built-in Security app in MIUI has a "Schedule Cleanup" feature, activate it so that the phone deletes temporary files at night when you're not using it.

You can also disable auto-save media files in instant messengers, and in the Telegram, WhatsApp and Viber settings, you can prevent the images from being saved to the gallery, they will remain available inside the chat, but they will no longer clog the phone's memory with duplicates.

Check the installed list regularly. If you haven't used it for more than a month, you'd better delete it. Modern smartphones have enough memory, but it's not unlimited, and the background processes of heavy applications can slow down the system.

• ⏰ Set up automatic cleaning in the Security app.
• 🚫 Turn off auto-save media in the settings of messengers.
• 📉 Remove apps you haven’t used for more than 30 days.
• ☁️ Move photos and videos to cloud storage.

⚠️ Attention: Third-party cleaner apps (Clean Master and analogues) often work more aggressively than embedded tools and can delete the desired data or display ads.
