Lack of memory on the Xiaomi phone: what to do and how to clean

The memory shortage on Xiaomi is familiar to almost every smartphone owner of this brand. Storage overflow notifications appear at the most inopportune moment, blocking installation of updates, creating new photos or launching favorite games. Android system, especially the MIUI shell or the new HyperOS, requires constant free space for correct operation of background processes and temporary files.

Ignoring this problem can lead to serious consequences: the device will start to work noticeably slower, applications will fly out immediately after launch, and in the worst case, the smartphone can go into an endless reboot. Internal memory is not just a warehouse for your photos, it is the workspace of the processor where the system places temporary data. If this area is crammed to the end, the operating system simply has nowhere to “deploy” to perform operations.

Fortunately, Xiaomi’s ecosystem offers a variety of built-in diagnostic and cleaning tools that don’t require third-party software installation. In this article, we’ll look at all the effective ways to free up space, from simple manual cleaning to radical but effective resetting methods. You’ll learn how to find hidden files, clean the app cache, and properly configure cloud sync.

Storage Occupancy Analysis: Finding Hidden Consumers

Before you delete files at random, you need to determine exactly what is eating up precious gigabytes. The standard storage analyzer in MIUI often shows the big picture, but misses the details. For more in-depth analysis, go to Settings → Memory and wait for the scan to finish. The system will automatically categorize the data, but sometimes the heaviest files are hidden in the Other folders.

Special attention should be paid to the Download folder. Many users have been downloading installations for years. APK-file, PDF-These files can weigh several gigabytes, occupying up to 30% of the total storage. DCIM →.thumbnails, where you store thumbnails of your photos – this gallery cache can grow to unimaginable sizes.

⚠️ Note: When manually cleaning folders through a file manager, be extremely careful with system directories whose names contain the words "Android", "Data" or "Obb." Deleting files from these folders can lead to loss of progress in games or malfunctioning applications.

To visualize the structure of files, you can use third-party tools like DiskUsage, which show the memory card as blocks, which allows you to instantly see the largest files, even if they are hidden deep in the system, and once you detect heavyweights, you can make an informed decision about deleting or transferring them.

Cleaning the cache and removing system debris

The fastest way to free up space is to use the built-in Security app, which is a system tool that is deeply integrated into the shell and has access to areas closed to conventional cleaners. Launch the app, click on the Cleanup button and wait for analysis to be completed. The system will suggest removing temporary files, cache and remnants of deleted applications.

However, automatic cleaning does not always remove the cache of heavy messengers such as Telegram or WhatsApp, as they are marked as “important data.” To clear them, you need to go to Settings → Apps → All apps, find the desired application (for example, YouTube or TikTok) and select Storage. There you will see the “Clear Cache” button – it is safe and will not delete your correspondence or accounts.

The cache of Google Play and Google Services Framework deserves special attention. If these services work incorrectly, they can accumulate errors and take up space. Cleaning their cache often solves problems with downloading applications and frees up additional megabytes. Remember that regular prevention (once a week) helps keep the system on top and prevents critical overflow.

💡

Use the Deep Clean feature in the Security app to find duplicate photos and large files you may have forgotten to delete.

Optimization of messengers: Telegram, WhatsApp and Viber

The leaders in memory consumption on any Android smartphone, including Xiaomi, are instant messengers. Telegram, WhatsApp and Viber by default store all received photos, videos and voice messages in internal memory. Over time, the folders of these applications can grow to 10-20 GB or more, which is a significant part of the available space.

Telegram has a built-in and very powerful memory management tool. Go to Settings → Data and Memory → Memory Use. Here you will see a "Storage Media" slider. Set a value for example, "3 days" or "1 week." After that, click "Clear Telegram cache." Importantly, your photos and videos will not disappear permanently, they will remain on the server and will be downloaded again as needed when viewed.

WhatsApp is more complicated because it doesn't automatically clean the cache in the same way. You'll have to manually delete files through the file manager periodically. Find the Android → media → com.whatsapp → WhatsApp → Media. Inside you're interested in the Sent and Private folders. Often, it stores copies of photos that you already have in your gallery, creating duplicates.

Also in the settings of each messenger, it is recommended to disable the auto-save of the received media files in the phone gallery, which will prevent copies of images from chats from appearing in the main photo feed, which will significantly save space and remove visual noise.

Gallery Work: Compression and Cloud Technologies

High-resolution photos and videos are the main memory consumers on modern Xiaomi smartphones. One minute of video in 4K can take up to 300 MB. If you don’t have enough memory on a Xiaomi phone, the first thing to do is analyze the album “Video” and “Screenshots.” Often there are unsuccessful takes or long screen recordings that are no longer needed.

Use Google Photos or Mi Cloud to free up local space. Google Photos has a "Free up space" feature that removes photos and videos from your device that have already been successfully uploaded to the cloud, a safe way to reduce the amount of space you occupy by allowing you to access media files over the Internet.

For users who do not want to depend on the Internet, the HEIC format (for photos) or compressed video will suit. In the Xiaomi camera settings, you can change the video resolution from 4K to Full HD (1080p) or turn on storage optimization mode. The difference in quality on the smartphone screen will be minimal, and the file volume will decrease by 3-4 times.

⚠️ Note: Before deleting the original photos, make sure that the sync with the cloud is complete. Check for photos through the browser on your computer by logging into your Google or Mi Account.

Also, remember to check the Recycle Bin album in the gallery. Deleted files are stored there for another 30 days, taking up space. Cleaning up the Recycle Bin is an instant way to get back a few gigabytes if you've recently done a photo review.

Removal and freezing of unused applications

Many apps that are preinstalled or downloaded by the manufacturer are just dead weight, they may not be used for months, but they will take up space and even update in the background. Go through the list of all the apps in the settings and sort them by size or date of last use.

Games are a separate category of memory eaters: Modern projects like PUBG, Call of Duty or Genshin Impact can take anywhere from 5 to 15 GB each. If you're not playing them right now, you'd better delete the game. If you re-install all the progress (if it's linked to your account) will be saved and the space will be free for your current needs.

💡

Removing a single major game can free up more space than clearing the cache of hundreds of smaller apps.

For system applications that cannot be removed by standard means (e.g. Mi Video, Mi Music, if you don't use them), you can use the "Disable" feature, which will hide the application and prevent it from updating, although it will take up space anyway. For advanced users, there is a possibility of removing system debris through ADB-computer commands, but this requires caution.

Consider using “Lite” versions of apps (Facebook Lite, Messenger Lite), which consume significantly less space and RAM, while retaining basic functionality, especially for low-end Xiaomi models with little internal storage.

Expanding memory by means of SD-maps OTG

If software methods are exhausted and the space is running out, consider the hardware extension. Most Xiaomi smartphones (except some flagship series) support microSD cards. You can transfer photos, videos, music and documents to them, freeing up internal memory exclusively for applications and the system.

To transfer data, use the file manager. Select files, click "Move" and specify the path to the file. SD-Some applications allow you to change the way you save data to an external map in your settings, for example, in Spotify or Yandex.Music you can specify the saving of tracks on the external map. SD-map.

An alternative could be a flash drive with OTG. If you need to urgently throw over the archive of photos or videos to make room, connect USB-It's a temporary, but very effective solution for a one-time, large cleanup without permanently deleting important data.

Radical measures: Resetting to factory settings

When all methods have been tried, but the system continues to run unstable and writes that there is not enough memory, the last argument remains: a complete reset, which returns the phone to the state of “out of the box”, removing absolutely all user data, settings and applications.

Before you start, make sure to create a full backup. Xiaomi has a built-in "Mi Mover" app or backup function in Mi Cloud. Save contacts, photos and important documents to your computer or the cloud. Without a backup, you risk losing all information irretrievably.

Path to reset: Settings → About phone → Resetting → Erase all data

Once reset, the phone will work as fast as possible, as it will not have accumulated years of garbage, residual files of remote programs and configuration conflicts, which often “revives” even old smartphones, making them responsive, as on the day of purchase.

⚠️ Warning: Make sure the battery is at least 50-60% Interrupting the process by turning off the phone can damage the system partition and require flashing the device.
