Xiaomi’s internal memory is full: 7 proven ways to free up space

Xiaomi's internal memory is one of the most common headaches users have. Even on devices with 128GB or more, the system suddenly starts to issue a warning: "Memory is full." The settings can show that there are another 10-15GB free. What's the catch? MIUI reserves some of the memory for system needs, and also actively caches the application data. But the main problem lies in the hidden debris that accumulates over time: duplicate photos, messenger cache, remnants of deleted programs and temporary updates.

Especially acute is the issue for the budget models Redmi and POCO with 32 or 64 GB of memory. Here every gigabyte is in the account, and the system can “eat” up to 30% of the total. But even owners of flagship Xiaomi 13/14 face overflow due to active use of a camera with a resolution of 50+ MP or recording video in 4K. In this article, 7 working methods to free up memory on Xiaomi without losing important data, including hidden tricks that are not written in the official instructions.

1. Memory analysis: where exactly is the garbage sitting?

Before you clean it, you have to figure out what's taking up space. MIUI has a built-in analyzer, but it often doesn't show the data accurately. It can display 20GB of System Data, for example, when it's actually only 5GB. To get a true picture, you have to get a picture.

1. Go to Settings → About the phone → Memory.
2. Slip on the schedule of use - the detail will open.
3. Pay attention to the items "Cash", "Downloads" and "Other" - this is where garbage is most often hidden.

For a deeper analysis, use third-party utilities like Files by Google or SD Maid.

• 📁 Duplicate photos (especially relevant after transferring from iPhone or other Android).
• 🗑️ Remnants of Remote Applications (Folders) /data/app-lib and /data/data).
• 🎬 Unproven files from Torrent or browsers.
• 📱 Cache of messengers (in Telegram and WhatsApp can take up to 5-10 GB!).

Critical MIUI error: the system can show that the memory is 100% full, although in fact free 1-2 GB. This is due to the fact that MIUI reserves up to 5 GB for "reserved storage" for updates. If you see this, do not panic, it is not a bug, but a feature.

2. Clearing cache and temporary files

The fastest way to release 1-3 GB is to remove the cache, but it is important not to overdo it: cleaning the cache of all applications at the same time can cause malfunctions in some programs (for example, banking or social networks).

• 🧹 Cache of individual applications: Go to Settings → Annexes → App management, select a program (like Telegram or Instagram) and click "Clear Cache." For instant messengers, this can give you a chance to use it. +500MB - 2GB.
• 🗑️ System cache: In Settings → Memory. → Clean up the app by tapping "Junk Files" and select "Deep Clean." Don't use the "Clean Up Acceleration" option, it deletes the application preload data, which will keep it open longer.
• 🔄 Cache updates: After installing updates MIUI It often doesn't delete temporary files. They're in a folder. /cache and can weigh up 1 GB. To delete them, go to Settings. → The phone. → Update system, click on three dots in the upper right corner and select "Delete service pack".

Clear the cache of messengers (Telegram, WhatsApp, Viber)

Delete temporary files from the /Download folder

Clear the cache of Google Play Services and Play Market

Remove the old ones APK-file /APK

Clear your history in the browser (Chrome, Mi Browser)-->

⚠️ Note: Do not clear the cache of Google Play Services, Mi Account and Security applications - this can cause malfunctions in the work of Xiaomi and Google services.

3. Removal of duplicates and unnecessary media files

Photos and videos are the main memory eaters, and even if you think you don't have many, check out:

• 📸 Duplicate photos: When you transfer from an iPhone or other Android, copies with other names are often created (for example, copies with other names, IMG_1234.jpg and IMG_1234(1).jpg).
• 🎥 Videos from messengers: Telegram and WhatsApp by default save all received videos in the folder /WhatsApp/Media or /Telegram/Telegram Video.
• 🔍 Screenshots and Screen Recordings: Folder /Pictures/Screenshots It can weigh a few gigabytes if you do screenings often.
• 🎵 Audio files from social networks: TikTok, Instagram and VK Store music and voice messages in the folder /Music or /Notifications.

How to find and delete:

1. Use the built-in File Analyzer in Files → Categories → Images / Videos.
2. To find duplicates, install Files by Google or CCleaner.
3. To avoid re-accumulation of garbage, turn off auto-save media in messengers: Telegram: Settings → Data and memory → Media auto-boot → Turn off for mobile data and Wi-Fi. WhatsApp: Settings → Storage → Media auto-boot → turn off for photos, videos and audio.

💡

If you often take screenshots, turn on compression in the settings: go to Settings → Additional → Screenshots and activate the option “Squeeze Screenshots Compression” This will reduce their weight by 30-50%.

4. Transfer data to a memory card or cloud

If you have a microSD slot on your phone, you can transfer some files to it, but note that not all apps support external memory.

• 📷 Photos and videos (folders) DCIM, Pictures, Movies).
• 🎵 Music and Podcasts (Music folder).
• 📄 Documents (PDF, Word, Excel from Documents folder).
• 🎮 Game saving (if the game supports external storage).

How to move:

1. Insert a memory card (UHS-I U3 class is recommended for speed).
2. Open the Files app, select the desired folders and tap "Move".
3. Select a memory card as your destination.

For models without a microSD slot (such as the Xiaomi 13 Pro or POCO F5), use cloud storage:

⚠️ Note: If you transfer applications to a memory card through Settings → Annexes → Move it to SD, Also, some programs (such as WhatsApp or banking apps) do not support transfer to external storage.

5. Removal of system debris and application residues

Even after you delete the applications, you still have the residual files, folders with settings, cache and data, which can take up to 500 MB per application, to delete them:

1. Install SD Maid (requires root rights for deep cleaning) or Files by Google.
2. Run the scan on "App Corpses in SD Maid".
3. Delete the folders you find manually through the file manager (path: /data/data/[name packet]).

Also check the following folders for debris:

• 📂 /Android/data — Here data of games and applications are stored.
• 📂 /Android/obb — game cache files (e.g, PUBG Genshin Impact can be used to 5 GB!).
• 📂 /Download — old-fashioned APK, archives and under-quality files.
• 📂 /MIUI/Backup — backup copies created by the system.

Hidden MIUI garbage: The system backs up settings in /MIUI/Backup/AllBackup. If you don't use the backup function, safely delete all the contents of this folder - this can give +500 MB - 1 GB of free space.

6. Optimization of applications

Some programs inflate over time, taking up an unnecessarily large amount of space.

• 🎮 Games like Genshin Impact or Honor of Kings take up to 10 GB. Remove unnecessary resources: in the game settings, find the option "Storage Management" and remove unused language packs or HD-texture.

Lifehack for MIUI: disable Interface Animation — it won’t free up memory, but will speed up the system. Go to Settings → About Phone → MIUI Version (tap 7 times to turn on Developer Mode), then to Settings → Additional → For Developers and turn off all animation options.

💡

Regular cleaning of the cache of messengers (Telegram, WhatsApp) and streaming services (YouTube, Netflix) can free up to 5 GB of memory per month.

7. Reset to factory settings (last resort)

If nothing works and there is a critically low amount of space (less than 1 GB), it will be hard to reset, which will remove everything from the phone, including apps, photos and settings, but will return the device to a "clean" state.

Backup photos and videos (Google Photos, computer)

Save contacts (synchronize with Google or export to VCF)

Write down logins/passwords (use password manager)

Make sure there are no associated devices in your Mi Account (re-authorization may be required)

Remove the memory card (if any)-->

How to reset:

1. Select "Erase all data."

After discharge:

• 🔄 Do not restore backup through Mi Cloud – it can return old garbage.
• 📱 Install only the necessary applications.
• 📁 Transfer media files to a memory card or cloud immediately after recovery.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3 Pro) after the reset, the error "Device failed to activate" may appear, this is due to the link to the Mi Account. To avoid blocking, untie the device before the reset in the account settings on account.xiaomi.com.
