How to find and clean up internal memory on Xiaomi Redmi

Xiaomi and Redmi smartphone owners often face situations where the device is slowing down or stops installing app updates. These are classic signs of internal storage overflow. Unlike computers where we see separate C and D drives, in the Android mobile system, the file structure can seem confusing. Users often confuse RAM and persistent storage (ROM), although it is the latter that is responsible for saving your photos, videos and installed programs.

Understanding how the file system works on your gadget is critical to its long life. When the space is running out, the system can't create the temporary files needed to run applications. The cache is inflated, and there's no place to write new data. In this article, we'll go into detail about where to look for information about occupied space and what tools the MIUI or HyperOS shell offers for managing files.

Don't ignore the warnings about space shortages. It's not just an inconvenience, it's a risk of data loss or database corruption. We'll look at the regular analysis methods, hidden features and secure ways to free gigabytes. The system partition on Xiaomi is reserved and not available for user recording, so trying to clean it manually can lead to crashes. Let's figure out what to touch and what to leave alone.

Differences between RAM and ROM in Xiaomi smartphones

The first step to managing the device's resources properly is to understand the memory architecture, and many users, when they see the words "6 GB of 8 GB occupied," panic, even though they are talking about very different things. RAM is a fast storage system where applications that are running right now are temporarily located, and it is cleared automatically when programs are restarted or closed.

On the other hand, persistent memory (ROM), often referred to as internal memory or storage, stores data even after the phone is turned off. This is where your operating system, photos, music and instant messenger files lie. On Redmi and Poco smartphones, the ROM volume is fixed and depends on the model you buy (64, 128, 256 GB, etc.).

It's important to not confuse these concepts when you read specifications or error messages. If the system says "Not enough memory," 90% of the time it's about overflowing permanent storage (ROM), not operational. Cleaning RAM through task manager only gives you a temporary increase in performance, while freeing up space in the ROM solves the problem long-term.

Modern versions of Android based on MIUI use dynamic expansion of RAM technology. Part of the permanent storage can be reserved for RAM. This means that the physical volume of space available for files may be slightly less than the specified space, and that is normal.

How to view the occupied place through the system settings

The most reliable and secure way to find out what is eating your space is to use the built-in tools. Xiaomi’s shell provides fairly detailed statistics that do not require third-party installation. To get there, you need to go to the Settings menu, then select About phone and click on the Warehouse bar.

In the window that opens, you'll see a color diagram that shows you the distribution of data, and it automatically categorizes files, making it much easier to find heavyweights, and you can see separately the volume of applications, images, videos, audio files and documents, and you can quickly understand where the space is going.

Special attention should be paid to the "Other" or "System Data" section, often where error logs, remnants of remote programs or cache of system services accumulate, clicking on any category, you will be taken to a detailed menu where you can delete unnecessary files or go to manage a particular application.

💡

If the Others partition takes up a suspiciously large amount of space (more than 10-15 GB), try backing up and resetting to factory settings. This often helps to remove software errors from garbage accumulation.

You can use a hidden menu of engineering tests to analyze it more deeply, but it's better for the average user to stay out of it, and the standard interface is enough for 95 percent of cleaning tasks, and the key is to check this section regularly to keep it from critically filling.

Using the Security Application for Cleaning

Each Xiaomi smartphone has a Security system app, which is a powerful tool not only for virus protection but also for memory management. Unlike the standard settings menu, it is sharpened for quick cleaning with one touch. Launch the app and select the Cleanup icon.

The system automatically scans the device for temporary files, installation residues. APK-files and cache of popular applications. MIUI They're smart enough to tell important data from junk, but it's always worth checking the scan results before you delete it, and you'll see a list of recommendations that you can safely remove.

The Deep Clean feature, which allows you to find large files you may have forgotten or duplicate photos, also allows you to control the autoload of applications, which indirectly affects performance, although it does not free up storage space directly.

It's worth noting that aggressive cache cleaning can cause applications to load a little longer on their first run after cleaning, which is normal because they have to recreate temporary files, but using this tool regularly helps keep the system on track.

⚠️ Note: The Security app has a memory acceleration function (RAM), Don't use it too often, because Android manages RAM efficiently, and constantly rebooting apps only consumes battery power.

Analysis of folders of messengers and social networks

The main “eaters” of internal memory on modern smartphones are messengers. WhatsApp, Telegram, Viber and Instagram store every photo and video received in the memory of the device by default. Over time, these folders can grow to tens of gigabytes, stealthily occupying all available space.

To find these files, you can use the standard File Explorer (or Mi). Drop/The conductor depending on the version MIUI). You need to go to the root directory of internal memory.The path to messenger data in new versions of Android (11 And above that, because of Google's security policy, they're often on the way. Android/media/com.whatsapp or Android/data.

Inside the messenger folders, look for Images, Video and Documents directories, and that's where all the media files from the chats are stored. Often you can find old greetings, cards and videos that you don't need anymore, and deleting them through the file manager will make room, but it will also remove them from correspondence.

A safer way to do this is to use built-in cleaning tools inside the apps themselves, for example, Telegram has a data and memory section → memory usage where you can set up autodeletion of the cache, which allows you to store media in the cloud, taking up minimal space on the device.

Table: Location of system folders in different versions of Android

The file system structure changed with the release of new versions of Android. On older Redmi devices with Android 9 or 10, access to folders was easier; on newer models with Android 12, 13 and higher, access to system directories is limited. Below is a map of the path correspondence.

As you can see from the table, the user's personal files (photos, downloads) have kept their usual paths, with major changes to the application data folders (Android/data), which are now often blocked by the system for security reasons.

If you can't find the folder you want, search by file. Enter a file extension (like.mp4) or part of a name. This is often more effective than wandering through directories, especially given the changes in the structure of Android 11+ files.

Expanding memory by means of SD-maps and clouds

If internal memory is physically limited and you don’t want to delete anything, there are two options: external storage or cloud services. Not all modern Xiaomi models support memory cards, so check for a microSD slot in the tray first. SIM-If you have a slot, you can move some of the data there.

The system allows you to format the memory card as an internal storage (Adoptable Storage), although this feature is often hidden or unstable on MIUI. A more reliable option is to configure the card as a portable storage and transfer photos, videos and music to it. To do this, select the card in the storage settings and click "Use as internal storage" (if available), or simply move the files manually.

Alternatively, Xiaomi Cloud cloud storage or third-party services like Google Photos, if you set up the gallery sync, you can turn on the "Free Space" feature, and the app will upload the originals to the cloud and remove them from the phone, leaving only thumbnails.

💡

Using cloud services is the most modern way to solve the problem of memory shortage, allowing you to access the archive from any device without space on your phone.

When using memory cards, keep them in mind, because cheap cards can slow down applications if they have programs installed on them, for photos and videos, a U1 or U3 speed card will do. Don't skimp on the memory card, because losing photos due to a breakage will cost more.
