Why this section takes up so much space – even if you haven’t installed new apps in a long time. 3. How to reduce its size without losing important data and without resetting the phone to factory settings. 4.

Warning: Not all tips on the Internet to clean the Other are safe, such as deleting a folder. /data/app-lib Root can lead to app crashes, and cleaning Dalvik-cache without knowing it can lead to a cyclical reboot of the phone. MIUI 12–14 Android 10–14.

What is “Other” in the memory of Xiaomi: a complete analysis

The official documentation of Xiaomi and Google defines the "Other" section as "files that cannot be classified as standard categories." But that's too vague.

  • 📁 Application cache and systems are temporary files that are created to speed up the operation of programs, such as the cache of Google Play Services or the cache of Google Play Services. MIUI Gallery.
  • 🗃️ Residual files of remote applications are “tails” that remain after uninstallation of programs (folders in the file). /data/data, settings, logs).
  • 🔄 Update files – Update packs that are downloaded but not installed MIUI or.
  • 📱 System logs and dumps are debugging files (.log,.dump) that are created when crashes or for diagnostics.
  • 🔐 Encrypted data – for example, files DRM for streaming services or Mi Account data.
  • 🧩 Virtual machine files – if you are using them MIUI+ or other virtualization functions.

Feature Xiaomi: in the “Other” also get files of themes design (MIUI Themes that you've ever downloaded, even if they're not active now, and cache system applications like Security, Cleaner, or Mi Video.

Why does this partition grow over time? Because Android doesn't always clean temporary files properly, especially after:

  • ⚡ Updates MIUI (There are old versions of the files).
  • 🔄 Changes to Fastboot or Recovery.
  • 📱 Use functions like Dual Apps (cloning apps) or Second Space (second desktop).
📊 How often do you clean your memory on Xiaomi?
Once a week.
Once a month
Only when the place ends.
Never clean.

Why does the Other take up so much space on Xiaomi (and not on other phones)?

If you compare two phones with the same set of apps – for example, Xiaomi Redmi Note 12 and Samsung Galaxy A54 — You'll see that Xiaomi always has a bigger "Other" section. MIUI:

  1. Aggressive caching. MIUI It's actively caching data to speed up the interface, like animations, icons, gallery previews.
  2. Duplication of theme files. Each theme of the design (MIUI Themes saves its resources in a separate folder, even if you haven’t used it for a long time.

Another nuance: on Xiaomi with extended memory (Virtual) RAM) The other partition can take up a swap file, which is used to increase RAM, and can be as large as 2-6 GB depending on the model.

The reason for the growth of the "Other"Typical size (GB)Can it be cleaned safely?
Cache of system applications (MIUI Gallery, Security)1–3Yes (partially)
Residual files of theme (MIUI Themes)0.5–2Yes.
Logs and dumps of the system0.3–1Yes (but not all)
Update Files (OTA)0.5–2Yes.
Swap file (swap)2–6No.

It's important to understand that not all Others can be deleted, such as Dalvik-cache files or application lib libraries that are critical to the system, and deleting them without Root access and knowledge will cause disruption.

💡

If the Other partition takes up more than 10GB, first check if you have Virtual enabled. RAM (It creates a paging file that can take up to 6GB and display as "Other».

How to safely reduce the “Other” on Xiaomi: step-by-step instructions

Before you start cleaning, back up your sensitive data (photos, contacts, messages) and even secure methods can result in the loss of unsaved files.

The methods of cleaning the “Other” section are divided into three categories:

  1. Built-in tools MIUI — No need for additional programs.
  2. Third-party utilities - for deep cleaning (for example, SD Maid or Files by Google).
  3. Manual cleaning – for experienced users (requires access to the file system).

Let’s start with the safest method, the built-in tools.

Method 1: Cleaning through “Security” and “Storage”

This method is suitable for all Xiaomi models (including Redmi and other models). POCO) and does not require Root rights.

Open the Settings. → Warehouse|Click on the "Other" section»|Select “Clean” or “Delete Unnecessary Files»|Reboot the phone.

  1. Go to Settings. → Warehouse.
  2. Slip on the "Other" section, and the system will scan the files and show you what you can delete.
  3. Click on “Clean” or “Delete unnecessary files». MIUI Automatically delete cache, temporary files and logs.
  4. Restart the phone – it is necessary for the system to recalculate the occupied space.

This method usually frees up 1-3 GB, but doesn't always clean everything up. If the Other section is still large, move on to the next one.

Method 2: Delete cache and residual files through MIUI Cleaner

Appendix "Cleaner" (Cleaner) in MIUI Find and delete files that are not visible in the standard storage menu.

  1. Open the Security app (Security).
  2. Go to the “Cleaner” tab.
  3. Press "Deep Cleanup."
  4. Select “Unnecessary Files” and “Residual Files”.
  5. Confirm the removal and wait for the process to be completed.

Then check the "Other" section in the storage settings. If the changes are minor, try removing the cache of system applications:

  1. Go to Settings → Applications → Application Management.
  2. Sort the apps by size (click on the three dots in the upper right corner).
  3. Select system applications (MIUI Gallery, Security, Download Manager, Mi Video).
  4. In each of them, click "Storage» → «Clear the cache».

What happens if you delete /data/dalvik-cache?
Deleting this folder will cause the system to reassemble the cache the next time you run the applications, which can take a few minutes and cause slowdowns, and in some cases, it helps get rid of junk files, but without Root, you can't do that. If you don't have superuser rights, skip this step.
