How to Clean Up Xiaomi Phone Storage: A Complete Guide

Owners of Xiaomi, Redmi and POCO smartphones are faced with an unpleasant notification that internal memory is full.It is not just an annoying message that blocks installing updates or creating new photos.When the MIUI or HyperOS system partition is crowded, the device starts to run slower, applications can fly out and the system freezes. Cleaning up storage becomes a critical task to maintain the stability of the gadget.

There are many reasons why free space runs out so quickly, such as messenger cache that grows to gigabytes, forgotten high-resolution videos, or system error logs. Standard cleaning techniques often fail to deliver the full result because they hide the heaviest files deep within the directory structure. In this article, we will discuss professional space freeup methods available to the average user.

Before we start radical measures like resetting, we need to do a thorough content review, and the right approach will free up 10 to 50 gigabytes of space without losing important data. We'll look at the built-in tools, file manager and specific camera settings that are often ignored. Get ready to turn your overflowing smartphone into a fast and responsive device.

Memory analysis through embedded tools

The first step is always diagnostics. The MIUI Android operating system provides a powerful, if not always obvious, storage analysis tool that allows you to visually assess which file categories occupy the most space. Users are often surprised to find that the bulk of the data is not photos at all, but application data or system debris.

To start the analysis, go to the Settings menu and look for About Phone. Here in the Storage section, the system will scan and give a color diagram of memory distribution. Pay attention to the Others section, which is an often hidden area where temporary files and remnants of remote programs accumulate. By clicking on any category, you can go to detailed viewing and deletion.

⚠️ Warning: When cleaning the Others section through the standard menu, be careful. Deleting system logs is safe, but erasing folders with game data or card cache can lead to loss of progress or offline navigation.

Use the built-in Security utility that's pre-installed on all Xiaomi devices, and it has Cleanup, which scans your device for ad debris, large files and duplicates. The algorithms are customized to fit the MIUI file structure, making it more efficient than third-party devices, and using it regularly helps keep the system on track.

Working with the cache of messengers and social networks

The most voracious apps in the Android ecosystem are traditionally messengers. Telegram, WhatsApp, Viber and VK store every picture, video and voice message viewed in the phone’s memory. Over time, this data can take up tens of gigabytes. Simply deleting chat doesn’t always clean up media files completely, so manual intervention or deep customization is required.

Telegram, for example, has a built-in cache management mechanism that works very efficiently. Go to Settings → Data and memory → Memory Use. Here you will see the slider "Storage media files." Set a value for example, "3 days" or "1 week." All files viewed before this deadline will be automatically deleted from the device, but will remain available in the cloud messenger by click.

WhatsApp and Viber are more difficult to manage because they are less aggressive in managing storage. You'll have to use a file manager. Find an Android/media/com.whatsapp or WhatsApp/Media folder. Inside the WhatsApp Video and WhatsApp Images folder, thousands of unwanted files are often stored. Deleting the contents of the Private folder inside media directories will free up space from hidden statuses and temporary downloads.

Don't forget about social networks. VK and Odnoklassniki also cache news feeds. If you actively browse through the feed, the app saves thousands of thumbnails. In the settings of these applications (the "Application" section in the Android system settings), you can click the "Clear Cache" button. This is safe and will not affect your personal correspondence or saved photos, but will return several hundred megabytes of free memory.

Removal of duplicates and large files

Often, multiple copies of the same document or video downloaded from different sources are stored on the phone, which is almost impossible to find manually unless you have a dedicated tool. The built-in MIUI file manager (or "Conductor") has a duplicate search function that analyzes checksums of files.

Open the Explorer app and select the Categories or Tools tab. Find the Duplicates. The system will give you a list of files that are completely identical. You can choose which copy to leave (it is usually recommended to leave the one in the main folder, not in Downloads), and delete the rest. This is especially true for photos that may have been copied when synced with a PC.

Also worth paying attention to is the Big Files section, which often includes forgotten movies, TV shows or archives of games that you downloaded a month ago and don't plan to open anymore, and deleting one of these files with a volume of 2-3 GB can solve the problem of space shortage instantly. Be careful: do not delete files with the extension.obb or.xpk, unless you are sure that they are not necessary for installed games.

Cleaning the gallery and optimizing photos

Media is the most obvious memory consumer. Xiaomi's current cameras are high-resolution, and one minute of 4K video can take up to 400MB. If you don't use cloud services, the gallery quickly turns into a gigabyte black hole. First of all, check the folder "Recently Deleted." Photos deleted from the gallery are stored there for another 30 days, taking up space.

Use the photo compression function. MIUI has an optimization tool that can reduce the size of the photo without visible loss of quality for viewing on the smartphone screen. It is also worth checking the camera settings: if you do not plan to print photos on posters, switch the shooting mode from 108 MP or 200 MP to a standard 12 MP or 50 MP. The difference in detail on the phone screen is invisible, and the weight of the file is reduced by 3-4 times.

The Portrait and Live Photos modes deserve special attention: HEIF files or live images take up more space. If the space is critically small, you can convert old photos to JPG format through third-party converter apps and delete the originals, which will save visual information, but drastically reduce the amount of space you take.

💡

Enable sync with Google Photos or Xiaomi Cloud with Free Space, which will remove photos and videos that are already securely stored in the cloud from the device, leaving them available in the gallery over the network.

System folders and hidden garbage

Deep inside the Android file system, there is a specific piece of debris that you can't see when you're browsing, debugging logs, temporary update files, and leftovers from failed installations, that you'll need a file manager with permissions to view the system folders, although a standard explorer with hidden files enabled is often enough.

Find the MIUI/gallery/cloud folder. If you don't use the Xiaomi cloud, there may be thumbnails and sync cache. Also check the Android/data folder. This stores app data. Deleting folders with names of remote games or programs here is completely secure and often returns several gigabytes. However, only delete folders whose names you know and correspond to remote applications.

A special place is in the blob folder inside messenger directories or the.thumbnail folder in the system gallery. The.thumbnails file can grow to a huge size, because it's a database of thumbnails of all images ever seen. Deleting it is safe — the system will just create a new, smaller file the next time you open the gallery, but the free space will return instantly.

⚠️ Note: Never delete files from folders Android/obb System folders with names like com.android.providers, if you are not sure about the 100% This can cause the applications or the system to fail.

Use of cloud technologies and PC

If internal memory is physically limited, the best solution is to transfer archives to external media or to the cloud. Xiaomi offers 5 GB of free space in Xiaomi Cloud, but for large volumes it is better to consider Google Drive, Yandex.Disk or Telegram (Favorites channel works as an unlimited cloud).

Connect your phone to your computer regularly USB-Cable. Transfer the operating mode. USB c “Transfer of files" (MTP). Copy the folders. DCIM (Photos, Movies and Download to your computer's hard drive. Once you've successfully copied, delete these files from your phone. This is the most reliable way to backup and clear the place without the risk of data loss due to synchronization errors.

For those who do not want to depend on the Internet, there are USB-Type-C flash drives allow you to instantly transfer heavy files and video archives, and consider using a microSD card if your Redmi or Xiaomi model supports installation. In the camera settings, you can specify saving a photo immediately to the map, which will save internal memory.

💡

The combination of regular cleaning of the messenger cache and transferring old photos to the PC / cloud allows you to keep 64 GB of memory free by 20-30% even with active use of the smartphone.
