Lacking memory on Xiaomi: a complete guide to fixing

Xiaomi’s memory shortage is familiar to every smartphone owner, and suddenly the system starts to slow down, apps stop updating, and storage overflow notifications appear with alarming regularity, not just a minor inconvenience, but a signal that the system partition or user partition of internal memory is critically full, which can lead to instability of the entire Android operating system.

Why is it happening so fast? Today's apps take up gigabytes of space, and high-resolution photos and 4K video instantly eat up the space. Owners of budget models Redmi and Poco with a storage capacity of 64 or 128 GB face this problem more often, but flagships are not immune to overflow. Understanding the structure of the file system and the ability to properly manage data are key skills for comfortable use of the device.

In this article, we will discuss proven methods of freeing up space that will help not only remove excess, but also prevent problems in the future. You will learn to distinguish system debris from important data, use cloud services correctly and optimize the operation of the MIUI interface. Don’t rush to delete your favorite photos or remove applications – there are more effective ways to solve the problem.

Storage Analysis: Finding the Biggest Files

Before you start taking any radical action, you need to understand what exactly is taking up space on your device. Standard Android tools and the MIUI shell provide enough tools for initial diagnosis. Often, it turns out that half of the memory is occupied by forgotten videos from messengers or social network cache, which the user did not even know existed.

To start, go to the settings and look for the "Storage" section, and it shows you the visual distribution of space into categories: apps, images, video, audio, etc. Notice the "Other" section, which often hides temporary files and archives. If this partition is bloated to unimaginable sizes, it's worth doing a deeper cleaning through the built-in utilities.

Use Xiaomi's built-in Security app, which automatically scans your device for junk files, but don't blindly trust the automation, always check what's being removed, and sometimes important installation packages or saved documents get into the trash.

⚠️ Before mass cleaning files from the category “Downloads” or “Documents”, be sure to check their contents so as not to delete important work files or checks.

For deeper analysis, you can use third-party tools like DiskUsage or Files by Google to build a memory card that shows you which folders weigh the most, and that can find hidden large files that a standard explorer might not show up in the general list.

Cleaning cache and temporary messenger files

The leaders in the consumption of free space are invariably messengers: Telegram, WhatsApp and Viber, these applications store every photo, video and voice message viewed in the memory of the phone, over time folders with media files can grow to 10-20 GB or more, which is critical for devices with a small storage capacity.

Telegram is most effective at solving the situation with flexible cache settings. Go to Settings → Data and Memory → Memory Use. Here you will see the current cache size. Click Clear cache and you will instantly free up gigabytes of space. Importantly, this will not delete your correspondence or media, they are stored on the server and re-downloaded if necessary.

WhatsApp is a little more complicated, because all files are stored locally. Go to Settings → Data and Storage → Storage Management. Here you can sort chats by space and remove media from specific dialogues. It is also recommended to disable auto-save media to the gallery so that duplicates do not copy into the system album.

Don’t forget to cache other apps. Social networks (Instagram, VK, TikTok) are also actively cacheing the tapes viewed. Cache clearing in the app settings (Settings → Applications → All Apps → [Select App] → Clear → Cache) is secure and often returns several hundred megabytes of free memory.

Removing duplicates and unnecessary media files

Over time, the smartphone gallery accumulates a huge number of duplicates. You take a photo, then again, then clipped and saved as new — you end up with three versions of one image. In addition, screenshots of interfaces, saved memes from chat rooms and failed frames often lie dead weight for years.

Modern versions of MIUI and Google Photos can automatically find similar images. In the Gallery app, go to Albums and scroll down to Similar Photos or Duplicates, and the system will suggest picking the best options and removing the rest, which is a safe and quick way to clean up your mess.

And if you pay special attention to the Recycle Bin folder, the deleted files don't disappear forever, they move to a basket where they're stored for 30 days, and they keep taking up space, and you go to the Deleted album and you select Clear Everything, and then you physically empty the storage space.

If you have a lot of videos, consider migrating them. High-resolution video files weigh a lot. You can transfer them to your computer or external hard drive. You can use cloud services to store archived photos and videos, which are discussed below.

💡

Use the “Free Space” feature in Google Photos to automatically delete photos that are already securely stored in the cloud.

Use of cloud storage and data transfer

Cloud technology is a salvation for smartphone owners with a small amount of memory. Xiaomi Cloud, Google Drive, Yandex.Disk allows you to transfer your data to remote servers, leaving only thumbnails or links to files on your phone, which creates the illusion of infinite memory.

Xiaomi Cloud is deeply integrated into the system. It can automatically sync contacts, messages, notes and most importantly photos. Turn on gallery sync, and once you upload originals to the cloud, you can select the option "Storage Optimization." Originals will be deleted from the phone, and the gallery will remain their reduced copies, which take up minimal space.

Google Photos offers a similar feature with Express (formerly Storage) quality, which allows you to upload unlimited photos and videos for free (with some compression). Set up automatic download and backup so you don’t worry about data safety if your device is lost or broken.

To transfer large files that are not needed all the time but need to be on hand (documents, rare videos), it is convenient to use cloud-enabled file managers. You can move files to the cloud disk folder on your phone, and they will automatically upload to the network, freeing up local space.

Removal of applications and work with APK-file

Apps are another memory expense: Games can weigh 5-10GB, and social media over time swells to giant sizes. Do a software review. If you haven't run a game in six months, you probably don't need it. Delete it, and if you need it, you can always download it from Google Play again.

Pay special attention to the download folder (/storage/emulated/0/Download). Users often download installation files (APK) They install them, but they forget to delete the installer, and they don't need them anymore, and they take up space, and they may have old versions of the documents or they may have them. PDF-files whose relevance has long been lost.

MIUI has a dual-space app or app cloning feature. If you have two WhatsApp or Telegram accounts, remember that each cloned app sits as a full-fledged, separate software with its own cache. If the second account is rarely used, you might want to disable the clone.

⚠️ Warning: Do not remove system applications marked with a shield icon or with the status of "Important" if you do not know exactly what they are responsible for.

For advanced users, a cleaning method is available via ADB (Android Debug Bridge), connecting the phone to a computer, you can remove the system “bloatware” (pre-installed garbage), which cannot be removed in the usual way, but this method requires caution and knowledge, since an error can lead to the “bricking” of the device.

Optimizing the system and preventing overflows

Once cleaned, it's important to set up the system so that the problem doesn't come back in a month. MIUI offers a lot of automation tools. In the Security app, you can set up a schedule for automatic garbage cleaning.

Turn off auto-update apps over the mobile network if you have a tariff with a limit, but set auto-removal in messengers. Telegram you can set a timer: "Delete media if it was not viewed for 3 days / week / month." This ensures that the cache will not grow uncontrollably.

Check system updates regularly. Sometimes newer versions of Android and MIUI will have better data compression and memory management algorithms. Go to Settings → About Phone → MIUI version and check for updates.

💡

Regular prevention and setting up auto-removal in messengers is more effective than periodic manual cleaning of overcrowded storage.
