Where is the cache on the Android Redmi phone: search and clearing

Smartphone owners Xiaomi i Redmi often face a situation when the accumulated memory of the device suddenly runs out and the system starts to work slower. One of the main reasons for this phenomenon is the growing application cache system temporary files that accumulate in the depths of the file system. Understanding where this data is physically and logically located is the first step to properly optimizing the operation of your gadget without losing important information.

The cache is not garbage in the usual sense, but a buffer zone to speed up the loading of frequently used elements. However, over time, these files can become outdated, conflict with new versions of apps, or simply take up gigabytes of space. In the ecosystem MIUI i HyperOS the paths to this data may differ from the stock one Android, which often misleads users when trying to manually clear them through file managers.

In this article we will analyze in detail the architecture of storing temporary data on devices. Redmi. You'll learn the difference between the user cache, which can be deleted safely, and the system cache, which requires special attention. We will look at both standard methods through settings and advanced methods through recovery mode so that you can return your smartphone to its former speed.

The logical structure of storing temporary files in MIUI

To understand where the cache is locatedyou must first understand the logic of the operating system Android on shell MIUI. The system divides the data into several isolated sections, each of which has its own access level. Application user data is stored in a protected area that cannot be accessed by a regular file manager without superuser rights (Root).

The bulk of temporary application files are accumulated in a hidden system partition /data. This is where databases, settings, and the cache that speeds up apps are located. In this case, the system creates separate directories for each installed application, using their unique package identifiers.

It is important to note that attempting to manually delete files in these directories through third-party explorers often leads to errors in the applications or their complete refusal to launch. The system Android strictly monitors the integrity of the folder structure, and violating this hierarchy may require reinstalling the problematic software.

⚠️ Attention: Never try to delete files in a folder /data/data manually through a file manager with root access if you do not know exactly what a particular file is responsible for. This may lead to loss of saves in games or resetting banking applications.

In addition to the user partition, there is a system cache, which is stored in a separate partition cache. This section is used by the operating system itself to store temporary update data, installation logs and other service information. Clearing this partition is a safe procedure and is often recommended when system crashes occur.

Search and clear the cache through the standard smartphone settings

The safest and recommended way to manage temporary files on Redmi is to use the system's built-in tools. The developers Xiaomi have provided a convenient interface for monitoring and clearing memory, which does not require deep technical knowledge. This method ensures that you delete only unnecessary things without affecting important data.

To access cache management for specific applications, you need to go to the settings menu. The path may vary slightly depending on the version MIUI, but the general logic remains the same. You need to find the section responsible for managing installed apps, where information about the space occupied is hidden.

Inside the menu of each application you will see detailed statistics on memory use. The concepts of “Application Data” and “Cache” are clearly distinguished here. Clicking on the clear cache button will delete temporary files, freeing up space, but will save your logins, passwords and progress in games.

• 📱 Go to Settings and select Applications.
• 🔍 Click on Manage applications to view the full list.
• 🗑️ Select the desired app, click Storage and then Clear cache.

An alternative and faster way is to use the built-in “Security” (or “Security”) application, which is pre-installed on all smartphones Redmi. This tool automatically scans your device for junk files, including ad cache, residual files, and temporary system data.

Running a scan through this app only takes a few seconds. After completing the analysis, the system will offer to delete the found objects with one click. This is the most effective method for regular device maintenance, which helps maintain high performance without interfering with system files.

Physical path to cache files in the file manager

For advanced users who want to visually verify the amount of data occupied, it is possible to view the file structure through a standard explorer. However, it is worth immediately noting that direct access the main application cache (/data/data) is closed to ordinary users for security reasons.

However, a significant part of the cached data, especially media files, image thumbnails and downloaded documents, is stored in the public part of the internal memory. This data is often duplicated or stored in open directories that can be accessed through the Explorer application.

The main folders where the “visible” cache accumulates are usually located at the root of the internal drive. Here you can find a directory Androidwithin subfolders media and obb. It is in these sections that heavy game files and social network caches are often stored, which can be deleted manually.

Folder path	Content type	Deletion security
/Android/media	Application media files, music and video cache	Safe (applications will be downloaded again)
/Android/obb	Cache files of heavy games (textures, maps)	Deleting will reset progress in games
/DCIM/.thumbnails	Thumbnails of photos from the gallery	Safe (slows down opening galleries)
/MIUI/debug_log	System debugging logs	Completely safe

Particular attention should be paid to the folder .thumbnails in the directory DCIM. Over time, this hidden file can grow to several gigabytes, since the system stores thumbnails of all photos ever viewed. Deleting it will instantly free up space, but the next time you open the gallery, the phone may “think” a little, creating the preview again.

⚠️ Attention: The folder Android/obb contains data for launching games. If you delete the contents of this folder for the game you are playing, it will no longer run and will require you to re-download several gigabytes of data.

You can also find folders in Explorer with the names of popular instant messengers, such as Telegram or Viber, in the root of memory. Often, users do not realize that the cache of these applications is located there, and not in the system partition. Regularly cleaning the folder Telegram/Telegram Images can free up a significant amount of space.

Cleaning system cache through Recovery mode

When the phone does not work correctly, freezes or loads endlessly, standard cleaning methods may not be enough. In such cases, mode Recovery comes to the rescue - a special service environment that allows you to perform deep cleaning of system partitions, including the hidden cache of the operating system itself.

Entering this mode on smartphones Redmi is carried out by a combination of physical buttons when the device is turned off. This usually involves pressing the volume up key and the power button at the same time. After the logo appears Mi the power button can be released while continuing to hold down the volume until the menu appears.

In the Recovery menu, control is carried out using the volume buttons (up and down) and confirming the selection with the power button. You need to find item Wipe Data or Clear Cache. It is important not to confuse clearing the cache with a full reset (Wipe All Data), which will delete all your personal files.

Sequence of actions in Recovery:
1. Wipe Data
2. Clear Cache (Select this item!)
3. Confirm
4. Back to Main Menu
5. Reboot

The process of clearing the system cache usually takes no more than a minute. Once completed, the phone will prompt you to reboot. The first startup after such a procedure may take longer than usual, since the system will need to re-generate the necessary temporary files for stable operation.

This method is especially effective after major firmware updates MIUIwhen old system files may conflict with new ones. Clearing the cache in Recovery helps eliminate compatibility errors and improve the responsiveness of the interface without losing user data.

What to do if the Recovery menu is in Chinese?

If you end up in the Chinese Recovery menu, don't panic. The cache clearing item is usually second from the top in the first submenu. Focus on the hieroglyphs or the number of points: Wipe Cache is often located immediately after the reboot point. If there is a language choice (the last item in the main menu), select English.

Automating cleaning and using third-party utilities

Manually clearing the cache can become a chore if done too often. Fortunately, the ecosystem Android allows you to automate this process or use specialized utilities that do this in more depth than standard system tools.

There are many optimization applications, such as SD Maid or Files by Googlethat work successfully on devices Redmi. These apps can find “empty” folders, duplicate files and caches left over from already deleted applications, which a standard cleaner Xiaomi sometimes misses.

However, it is worth remembering that aggressive cache clearing by third-party apps can have the opposite effect. Constantly deleting temporary files forces the processor and disk to work harder to re-create this cache, which leads to increased battery consumption and heating of the device.

• 🚀 Use automatic cleaning in the Security application on a schedule.
• 🛡️ Avoid installing “RAM boosters”, they are often malicious Software.
• ⚙️ Configure automatic deletion of old messages in instant messengers.

In the settings of Android itself, starting with more recent versions, the “Adaptive Storage” function has appeared. It automatically deletes old backups and caches of apps you haven't used in a while. Enabling this feature in Google One settings or in the storage section can make a user's life a lot easier.

The impact of the cache on performance and memory life

Many users mistakenly believe that the cleaner the memory, the better the phone works. In fact, having a cache is critical to performance. When you open an application, the system loads part of the data into the cache so that the next time you launch it, it can be opened instantly, rather than reading slowly from the flash memory.

Constantly forcing the cache to clear forces the phone's drive to work in constant writing and rewriting mode. This not only wastes the resource of memory cells, reducing the theoretical lifespan of the drive, but also creates unnecessary load on the power controller.

The optimal usage scenario is to allow the cache to grow to reasonable limits. Modern versions MIUI i Android can manage this process themselves: when space runs out, the system automatically deletes the oldest and least used cache, making room for new data.

Problems arise only when a specific application begins to behave incorrectly and inflates its cache to abnormal sizes (hundreds of megabytes or gigabytes for a simple application). In such cases, a targeted clearing of the cache of this particular application is the only correct solution.

⚠️ Attention: Menu interfaces and item names may differ slightly depending on the firmware version (MIUI 12, 13, 14 or HyperOS). Always check the latest manuals for your specific model if the path described does not match.

Frequently Asked Questions (FAQ)

Will clearing the cache delete my photos and contacts?

No, Clearing the cache only affects temporary files that speed up applications. Your personal data such as photos, contacts, messages and notes are stored in the Data section and will remain untouched. However, be careful and do not press the “Clear all” or “Reset data” button if you do not want to lose information.

Why did the phone become slower after clearing the cache?

This is normal in the short term. After deleting the cache, the system and applications take time to recreate the necessary temporary files when they first start. At this moment, the processor and memory are working under load. Typically, performance is restored within 10-15 minutes of active use.

Is it possible to completely disable cache creation on Redmi?

Technically, it is impossible to disable caching in Android without deep modification of the system, which is not recommended for ordinary users. The cache is a fundamental operating system mechanism that ensures a smooth interface. Attempts to disable it will lead to constant freezes and extremely slow operation of the smartphone.

How to clear the cache if the phone does not turn on and hangs on the logo?

In this case, only entering Recovery mode will help. Turn off your phone (if possible by holding down the Power button for 10 seconds), then hold down the Power button and Volume Up. Select Wipe Data -> Clear Cachefrom the menu. This will remove system junk that could cause the download to fail without affecting your personal files.

Does the cache take up space in the Mi Cloud?

No, the application cache is stored exclusively in the internal memory of the device and is not synchronized with the cloud Mi Cloud. Cloud storage is intended for backup copies of contacts, messages, photos and system settings, but not for temporary cache files.
