Internal memory on tablets Huawei fills up faster than it seems: caching systems EMUI, background application processes and automatic updates eat up gigabytes unnoticed. If your device starts to slow down, displays notifications about low space, or refuses to install new applications, it’s time to clean up the memory. But simply deleting a couple of photos is not enough: comprehensive optimization is needed.

The peculiarity of tablets Huawei (series MatePad, MediaPad, T-series) is a proprietary shell EMUIthat aggressively reserves memory for system needs. For example, on Huawei MatePad 11 (2023) out of 128 GB out of the box, only ~100 GB is available to the user. The rest is taken up by firmware, pre-installed applications and service files. To this are added:

  • 📱 Application cache (up to 5-10 GB on an actively used device)
  • 🗑️ "Junk" files after updates and uninstallation of apps
  • 📁 Duplicates and temporary files (for example, from Huawei AppGallery or Petal Search)
  • 🔄 Background synchronization (cloud services Huawei Cloud, Google Drive)

In this article - unique cleaning methods that work specifically on Huawei tablets with EMUI 10–14, including hidden shell functions and bypassing manufacturer restrictions. Let's start with the safest methods and get to the "heavy artillery" - resetting to factory settings.

1. Analysis of occupied space: what exactly is eating up memory?

Before. clean, you need to understand which files take up the most space. IN EMUI there is a built-in storage analyzer, but it hides some of the data. Here's how to get the full picture:

  1. Open Settings → Memory.
  2. Tap on the graph at the top of the screen - details by category will open (Applications, Images, Video etc.).
  3. Click on a category (for example, Applications) → Sort by size.

Pay attention to:

  • 🔍 System applications (for example, Huawei Mobile Services or HiSuite) - they cannot be deleted, but you can clear the cache.
  • 📦 APK files remaining updates (folder /sdcard/Download/rom).
  • 🎮 Games with cache (for example, Genshin Impact or Call of Duty Mobile can weigh 10+ GB).
📊 How often do you clean the memory on your tablet?
Once a week
Once a month
Only when space runs out
Never

Hidden). folder .huawei (located in the root of the internal memory) often contains gigabytes of logs and temporary files. To see it, you will need a file manager that supports displaying hidden folders (for example, Solid Explorer or FX File Explorer).

⚠️ Attention: Do not delete files from folders /system, /vendor or /product —this will cause the system to crash. Also avoid the folder /Android/dataif you are not sure of the purpose of the files.

2. Clearing the application cache and system garbage

The cache speeds up the operation of apps, but over time it grows to uncontrollable sizes. On tablets Huawei it can be cleaned in three ways:

Method 1: Built-in utility Optimization

  1. Go to Settings → Battery → Optimization.
  2. Select Storage & Performance → Deep cleaning.
  3. Tick the boxes all categories (Cache, Residual files, Large files) and click Clear.

Method 2: Manual cleaning for individual applications

  1. Open Settings → Applications.
  2. Select an application (for example, YouTube or Facebook).
  3. Tap Memory → Clear cache i Clear data (warning: this will reset the application settings!).

Method 3: Via Huawei Phone Clone (for deep cleaning)

This application is designed to transfer data, but has a hidden cleaning function:

  1. Install Huawei Phone Clone from AppGallery.
  2. Select This old phone → Cleaning data.
  3. Follow the instructions - the utility will find up to 2-3 GB of "junk" files.

Delete the cache of social networks (Facebook, Instagram, TikTok)

Clear map data (Google Maps, Petal Maps, Yandex.Maps)

Delete temporary messenger files (Telegram, WhatsApp)

Scan the Downloads folder for unnecessary APKs and archives-->

System cache (not to be confused with the application cache) also takes up space. reset:

  1. Turn off the tablet.
  2. Hold Volume up + Power until the logo appears Huawei.
  3. V menu Recovery select Wipe cache partition (use volume buttons to navigate, power buttons to select).
  4. After cleaning, reboot (Reboot system now).
⚠️ Attention: Do not confuse Wipe cache partition with Wipe data/factory reset —the second option will completely reset the tablet!

3. Removing pre-installed applications (bloatware)

Huawei is known for the abundance of pre-installed software that cannot be removed using standard methods: However, there are workarounds:

Method 1: Disable via Settings

  1. Go to Settings → Applications.
  2. Tap on the three dots at the top → Show system processes.
  3. Select an unnecessary application (for example, Huawei Browser or Petal Maps).
  4. Click Disable (this will not remove the app, but will stop it from running and free up some memory).

Method 2: Removal via ADB (for advanced)

Requires a computer and enabled USB debugging:

  1. Connect the tablet to the PC and enable debugging (Settings → About phone → Build number (tap 7 times) → For developers → USB debugging).
  2. Download Platform Tools from site Android Developers and open the command line in the folder with adb.exe.
  3. Enter the command to view the list of packages: 
    adb shell pm list packages -f
  4. Find the name of the unnecessary package (for example, com.huawei.browser) and remove it: 
    adb shell pm uninstall -k --user 0 com.huawei.browser

List safe to remove packages (checked on EMUI 13):

Application Package name Freed space
Huawei Browser com.huawei.browser ~150 MB
Petal Maps com.huawei.mapapp ~300 MB
Huawei Music com.huawei.music ~200 MB
Huawei Video com.huawei.videoplayer ~250 MB

Important: Do not delete packages with names huawei.android, huawei.system or huawei.services —this will cause the system to crash. Also avoid deleting. data-i="180">), otherwise the services will stop working. data-i="184">4. Transferring data to external memory or cloud Huawei Mobile Services (com.huawei.hms), otherwise the services will stop working AppGallery And Huawei ID.

💡

Before removing packages via ADB, make a backup of your important data. If after cleaning the tablet starts to malfunction, reset it to factory settings.

4. Transfer data to external memory or cloud

If the internal memory is full photos, videos or documents. data-i="189">Transfer to microSD, they can be transferred to microSD or to the cloud. But there are nuances:

Transfer to microSD

  • 📁 Photos and videos: Use Huawei Gallery → select files → More → Move → Memory card.
  • 🎵 Music and documents: Using a file manager (for example, Files by Google) move folders to /storage/XXXX-XXXX/Android/data on the SD card.
  • 🎮 Games: Some titles (for example, PUBG Mobile) allow you to transfer the cache to SD through the game settings.

Important: On tablets Huawei s EMUI 12+ applications are installed on the internal memory by default. To change this:

  1. Go to Settings → Storage → Default storage location.
  2. Select Memory card (if SD is formatted how internal memory).

  1. Go to Settings → Smart Assistant.
  2. Disable Recommendations, Usage analysis i Memory optimization.
How to return factory animations?

To restore standard EMUI animations, go back to Settings → For Developers and reset the values to Animation scale: 1x. A reboot is not required, the changes are applied immediately.

6. Reset to factory settings: last resort

If none of the methods helped, and the tablet still gives the error "Insufficient memory", this remains hard reset. will delete all data, including:

  • 📱 Installed applications and their settings
  • 📁 Photos, videos, music (if they are not on SD card)

💡

Resetting to factory settings is the only way to completely remove viruses, system junk and fix EMUI errors if other methods did not help.

7. Prevention: how to avoid memory filling in the future

In order not to clear the memory every week, follow these rules:

  • 📵 Disable auto-update of applications in AppGallery i Google Play (or limit updates to Wi-Fi only).
  • 📥 Set up automatic cleaning v Settings → Memory → Auto-clean (set a schedule, for example, once every 3 days).
  • 🚫 Use "light" versions of applications (for example, Facebook Lite, Messenger Lite).
  • 🔄 Transfer regularly files to an SD card or cloud (set up automatic photo upload to Google Photos).
  • 🛡️ Install an antivirus (for example, Dr.Web Light) to prevent infection by malware that bloats memory.

For tablets Huawei s EMUI 13/14 it is useful to enable the function "Memory optimization":

  1. Go to Settings → Battery → Optimization.
  2. Activate Memory optimization i Smart cleaning.
  3. In the section Exceptions add critical applications (for example, instant messengers) to did not close background processes.

Hidden life hack: If you often work with documents, use Huawei Docs or WPS Office with saving files directly to the cloud (Huawei Cloud or Dropbox). This will eliminate the need to store local copies.

FAQ: Frequently asked questions about clearing memory on Huawei

🔹 Why does the memory quickly fill up again after clearing the cache?

This is normal behavior EMUI: the system actively caches data to speed up the process. To slow down the process:

  1. Limit background activity of applications in Settings → Battery → Launch applications.
  2. Disable automatic media downloading in messengers (for example, in Telegram or WhatsApp).
  3. Set the cache limit for individual applications via App Settings (root access required).
🔹 Is it possible to increase the internal memory of a Huawei tablet?

Physically - no, but you can:

  • Use microSD how internal memory (formatting via Settings → Memory).
  • Connect USB drive via OTG adapter (tablets Huawei support exFAT and NTFS).
  • Transfer some applications to SD (only if the card is formatted as internal).

Important: When formatting SD as internal memory, it is encrypted and linked to the device. After extracting, the data on it will not be available!

🔹 Why is the memory not freed up after resetting to factory settings?

Probable reasons:

  • The reset was completed incorrectly (for example, through Fastboot, and not Recovery).
  • System updates take up space (after a reset they can be automatically downloaded again).
  • Pre-installed applications restored (for example, Huawei Mobile Services).

Solution: After the reset, immediately disable automatic software updates in Settings → System → System update.

🔹 How to clear the memory if the Huawei tablet does not turn on?

If the device does not respond, try:

  1. Hard reset: Press Power + Volume up on 10–15 seconds.
  2. Recovery Mode: 
    1. Turn off the tablet.
    

    2. Press Power + Volume Up.
    

    3. In the menu, select Wipe data/factory reset.
  3. Fastboot (for advanced): 
    1. Connect the tablet to the PC.
    

    2. Enter the command:
    
fastboot erase cache
fastboot erase userdata

If all else fails, contact a service center - there may be a memory fault (eMMC).

🔹 Is it safe to use cleaning applications (for example, CCleaner)?

On tablets Huawei not recommended use third-party cleaners in two reasons:

  1. Conflict with EMUI: Applications like CCleaner or Clean Master can delete critical shell files.
  2. Spyware: Many "cleaners" collect user data (according to research AV-Test 2023).

Exception - Files by Google (from Google LLC), which safely finds duplicates and large files.
