Tablets Huawei based Android over time begin to “slow down” due to full memory. Even if you regularly delete unnecessary files, the system continues to accumulate temporary data, application cache and junk files that take up precious gigabytes. In this article we will analyze all current methods of clearing memory from basic to advanced, including hidden functions EMUI (Huawei proprietary shell) and working with external drives.

Features of tablets Huawei (for example, series MatePad, MediaPad or T-series) - in their hybrid file system, where the internal memory is often divided into several sections. This complicates manual cleaning, but opens up additional opportunities for optimization. We will show you how correctly analyze occupied spaceto avoid deleting important system files, and what tools to use to free up space as much as possible.

1. Analysis of used memory: what exactly is taking up space?

Before you start cleaning, you need to understand which files the memory is being clogged. Tablets Huawei have built-in tools for this, but they do not always show the full picture. Here's how to conduct an in-depth analysis:

Open Settings → Memory. Here you will see a diagram with memory distribution by categories: Applications, Images, Video, Audio and Others files. However, the built-in analyzer often hides system files and shell cache EMUI. For detailed scanning:

  • 🔍 Use third-party utilities like Files by Google or SD Maid —they will show hidden folders and duplicates.
  • 📁 Check the folder /Android/data/ —application data is stored here, which often weighs several gigabyte.
  • 🗑️ Pay attention to the section "Other files" in the memory settings. System log files, temporary updates and remnants of deleted apps may be hidden here.

If the section "System" is occupied by more than 10-15 GB - this is normal for EMUI, but if the figure exceeds 20 GB, you should check the tablet for viruses or file system errors. In such cases, resetting the cache through Recovery Mode (more about this in section 5).

2. Clearing the application and system cache

Caches are temporary files that applications create to speed up their work. Over time, they accumulate and can occupy up to 5–7 GB memory. In Huawei the cache is divided into two types:

  1. Cache of individual applications - cleared manually for each application.
  2. System cache - accumulated by the shell EMUI and requires special cleaning methods.

To clear the cache of an individual application:

  1. Go to Settings → Applications.
  2. Select the desired application (for example, YouTube or Chrome).
  3. Click "Storage" → "Clear cache".

To mass clear the cache of all applications:

  1. Open Settings → Memory → Clear memory.
  2. Select "Cache" and press "Clear".

Close all active applications|Connect the tablet to charger (for long operations)|Make a backup copy of important data|Check the free space after cleaning-->

⚠️ Attention: Do not confuse "Clear cache" and "Clear data". The second action will delete all application settings (logins, game saves, etc.), and you will have to configure it again.

3. Removing unnecessary applications and their remains

Many users delete applications through the icon on the home screen, but this does not always clear all associated files. In Huawei there are two types of applications:

  • 📱 Custom - installed by you from AppGallery or Google Play.
  • 🔒 System - pre-installed Huawei (for example, Huawei Mobile Services, HiCare).

To completely remove an application along with its data:

  1. Go to Settings → Applications.
  2. Select the application and click "Delete".
  3. If the button is inactive (gray), then the application is a system one. In this case, click "Disable"so that it does not work and is not updated.

For deleting remnants of already deleted apps:

  • Use Files by Google (section "Cleaning" → "Remaining files").
  • Check folders /Android/obb/ i /Android/data/ manually - heavy game files often remain here.
How to remove system applications without root access?

Without superuser rights (root), you cannot completely remove system applications, but you can disable them via Settings → Applications → Menu (⋮) → Show system ones. will be updated and occupy RAM. For complete removal you will need ADB (instructions in section 6).

⚠️ Attention: Removing system applications (for example, Huawei ID or Phone Clone) may disrupt the operation of the tablet. If errors appear after disconnecting, return the application to its original state via Settings → Applications → Menu (⋮) → Reset settings.

4. Optimizing multimedia files

Photos, videos and music often take up the lion's share of memory. Tablets Huawei have built-in tools for optimizing them:

File type How to optimize Memory saving
Photo Use Huawei Gallery → "Optimization" (compresses without loss of quality) Up to 50%
Video Convert to HEVC (H.265) via Video Compressor Up to 70%
Music Remove duplicates via Music Player → "Management" Up to 30%
Documents Archive to ZIP/RAR (for example, via RAR for Android) Up to 40%

To automatically clear garbage in the gallery:

  1. Open the application Gallery.
  2. Go to "Albums" → "Trash" and clean her.
  3. Enable the function "Auto cleanup" in the gallery settings (deletes files from the recycle bin after 30 days).

If the tablet has a microSD card installed, transfer multimedia files to it:

  1. Connect the memory card (if not already connected).
  2. Open Files → select the desired folders (for example, DCIM or Download).
  3. Click "Move" and select the SD card.
💡

Before transferring files to the SD card, format it format exFAT —this will allow you to store files larger than 4 GB (for example, 4K video).

5. Resetting the cache via Recovery Mode

If the tablet starts to slow down a lot, and standard methods do not help, try resetting the cache via recovery mode (Recovery Mode). This method does not delete personal data, but clears temporary system files that can slow down your work.

Instructions for tablets Huawei:

  1. Turn off the tablet.
  2. Hold the button power + volume up on 10 seconds until the logo appears Huawei.
  3. In the menu Recovery select «Wipe cache partition» (control - volume buttons, confirmation - power button).
  4. After cleaning, restart the tablet («Reboot system now»).

This method is especially useful after major updates EMUIwhen the system creates backup copies of old files, but does not delete them automatically.

💡

Resetting the cache via Recovery Mode does not delete photos, videos or applications, but may reset some settings (for example, Wi-Fi networks).

⚠️ Attention: Do not confuse «Wipe cache partition» and «Wipe data/factory reset»! The second option will completely reset the tablet to factory settings, deleting all your data.

6. ADB and manual cleaning

For experienced users who are ready to work with command line, there are deeper cleaning methods. One of them is using ADB (Android Debug Bridge. This method allows you to remove system junk that is not accessible through the standard interface.

What you will need:

  • 🖥️ A computer with drivers installed Huawei i ADB.
  • 🔌 USB cable (preferably original).
  • 📱 On mode "Debugging by USB" on the tablet (Settings → About phone → Build number (press 7 times) → Settings → System → For developers → USB debugging).

Commands for cleaning via ADB:

adb shell pm clear --user 0 com.huawei.appmarket # Clearing the AppGallery cache

adb shell pm uninstall --user 0 com.example.app # Removing a system application (replace com.example.app with a real package)

List of system application packages Huawei possible find on the Internet or through the command:

adb shell pm list packages | grep huawei
How to find the application package for ADB?

Open App Inspector (available in Huawei AppGallery) or use the command:

adb shell dumpsys package | grep "package:"

This will show all installed packages with their names.

⚠️ Attention: Incorrect use ADB can lead to loss of data or inoperability of the tabletIf you are not sure of your actions, it is better to refer to other methods from this article.

7. Last resort: reset to factory settings

If none of the methods helped, and the tablet still works slowly, remains full reset (hard reset). This will erase all data, applications and settings, returning the device to the same state as out of the box.

How to reset:

  1. Back up your important data (photos, contacts, documents).
  2. Go in Settings → System → Reset.
  3. Select "Reset all settings" or "Reset to factory settings".
  4. Confirm the action and wait for the reboot (may take 5-10 minutes).

After the reset:

  • 🔄 Restore the data from the backup (for example, via Huawei Backup or Google Drive).
  • 🚫 Do not install all applications at once - add them gradually to track which of them may again clog the memory.
  • 🛡️ Install an antivirus (for example, Dr.Web or Kaspersky) and check the tablet for malware.

⚠️ Attention: On some models Huawei (for example, MatePad Pro 2021–2023) after resetting, you may need to re-authorize in Huawei ID. Make sure you remember the password for your account, otherwise the tablet may be blocked!

FAQ: Frequently asked questions about clearing memory on Huawei

Is it possible to clear memory without losing data?

Yes, with most of the methods in this article (clearing the cache, deleting unnecessary files, optimizing multimedia) you will not lose personal data, however, resetting the cache through Recovery Mode or completely hard reset Everything will be deleted without the possibility of recovery. Always make a backup copy before major manipulations.

Why does the memory quickly fill up again after cleaning?

This happens due to:

  • Automatic caching of applications (for example, YouTube or TikTok download videos for offline viewing).
  • Background updates EMUI and Huawei Mobile Services.
  • Viruses or adware that downloads files without your knowledge.

Solution: disable auto-update of applications in AppGallery, limit background activity in the battery settings and regularly scan your tablet with an antivirus.

How to transfer applications to an SD card?

In the latest versions EMUI (starting from 10.0) transferring applications to the SD card is blocked by default. However, you can:

  1. Use the SD card as internal memory (formatted and becomes part of the main storage). To do this, when you first connect the card, select "Use as internal".
  2. Transfer only media files (photos, videos, music) manually via Files.

⚠️ After formatting the SD card as internal memory, it cannot be removed without losing data.

Which applications are best not to delete on Huawei?

It is not recommended to delete or disable:

  • Huawei Mobile Services (needed for the operation of branded services).
  • HiCare (support and update center).
  • Huawei ID (without it the application store and cloud service will not work storage).
  • Phone Clone (if you plan to transfer data from other devices).

Removing these applications may lead to errors in the tablet or the inability to update EMUI.

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

If the tablet Huawei does not respond to the power button, try:

  1. Hard reboot: hold down the power button + volume up for 15-20 seconds.
  2. Recovery Mode: if the tablet vibrates but does not turn on, try logging in Recovery (power button + volume up) and do «Wipe cache partition».
  3. Connecting to a PC: if the tablet is detected by the computer, use Huawei HiSuite for diagnostics.

If nothing helps, contact a service center - the problem may be in the hardware (for example, damaged flash memory).
