Restoring internal memory on an Honor phone: a complete guide

The internal memory of a smartphone Honor fills up faster than it seems: application cache, duplicate photos, residual files after updates and hidden garbage from EMUI (proprietary shell Huawei/Honor) are eating up gigabytes unnoticed. When the system starts giving warnings about low space, and the phone slows down when launching the camera or installing applications, it’s time to act. But simply deleting a couple of photos is not enough: you need system cleaningwhich will return performance without resetting to factory settings.

This article contains proven methods for restoring memory on Honor (relevant for models from Honor 8X to Honor Magic5), including hidden shell functions, working with ADB for advanced users and secure methods for transferring data. We'll look at why standard tips like "clear cache" often don't work, and what to do if the memory is full of unknown files. Important: some methods require root access or connecting to a PC - we will highlight them separately.

1. Diagnostics: why memory fills up on its own

Before clearing memory, you need to understand what exactly is occupying it. On Honor s EMUI (or Magic UI on new models) there are several “traps” due to which free space melts for no apparent reason:

• 📱 System partition /data: updates, error logs and temporary firmware files are stored here. For example, after updating through Huawei HiSuite there may be up to 3-5 GB of garbage left.
• 🗑️ Application cache: some apps (especially instant messengers and social networks) cache media files in the background. Telegram or TikTok can take up 1-2 GB without your knowledge.
• 🔄 Duplicates and “shadow” files: when transferring data from a PC or via Huawei Share copies are often created with names like IMG_20230515_123456(1).jpg.
• 🛠️ Hidden shell files: EMUI creates backup copies of settings, themes and widgets in the folder /Android/data/com.huawei.android.themes/.

To see the full picture, open Settings → Memory and tap on the usage graph. The system will show the distribution by categories: “Applications”, “Media”, “Files” and "Other" (often up to 30% of garbage is hidden here). If the “Other” section takes up more than 5 GB, proceed with deep cleaning.

2. Standard cleaning methods: what works and what doesn't

Most advice on the Internet boils down to two actions: clearing the cache and deleting unnecessary files. In practice this is not enough. Let's look at which built-in tools Honor really help, and which ones only create the illusion of free space.

2.1. Clearing the application cache

The safest, but also the most ineffective way. The cache is cleared automatically when there is insufficient memory, but some applications (for example Google Play Services or Huawei Mobile Services) restore it in a few hours. How to do this manually:

1. Go to Settings → Applications.
2. Select an application (start with the most “heavy” ones - instant messengers, games, browsers).
3. Tap Storage → Clear cache.

⚠️ Attention: Do not clear data (Clear storage) - this will delete accounts and settings in the application!

2.2. Built-in memory optimizer

In EMUI/Magic UI there is a tool Optimization (a brush icon in the notification panel or in Settings → System). It removes:

• 🗃️ Temporary application files.
• 📁 Empty folders.
• 🔍 Log files (log files).

However, the optimizer does not touch:

• 🚫 System application cache (for example, Huawei AppGallery).
• 🚫 Backups of themes and wallpapers.
• 🚫 Update files located in /data/ota_package.

2.3. Removing duplicates and unnecessary media files

Use the built-in application Gallery to Honor:

1. Open Gallery → tap on three dots → Management.
2. Select Duplicates or Blurred/unclear photos.
3. Delete unnecessary files (you can select all at once).

For video and music, use Files (application from Huawei):

• 🎵 In the Audio section, sort the tracks by size - often forgotten podcasts or voice messages lie here.
• 🎥 In Video check the folder DCIM/.thumbnails —thumbnails are stored here and can be deleted.

3. Deep cleaning: hidden folders and system junk

If standard methods did not help, it’s time to dig deeper. EMUI there are hidden folders and system files that are not shown in the standard file manager, but take up gigabytes. To work you will need:

• 📱 File manager with. access to root folders (for example Solid Explorer or FX File Explorer).
• 💻 PC with installed Huawei HiSuite (for backup).

3.1. Cleaning the folder /data/ota_package

Update files are stored here firmware. Even after installing the update, they can remain and occupy up to 2-4 GB:

1. Open the file manager with rights root (or use ADBif there is no root).
2. Go to /data/ota_package.
3. Delete all files with the extension .zip or .huawei.

⚠️ Attention: Do not delete files during the update process! Wait until the update is complete or cancel the update via Settings → System → Software update.

3.2. Deleting logs and memory dumps

The system EMUI keeps detailed error logs, which can occupy hundreds of megabytes. They can be safely deleted:

1. In the file manager, go to /data/log.
2. Delete files with extensions:
   • .log (application logs),
   • .dmp (memory dumps during crashes),
   • .trace (traces systems).

3.3. Clearing the cache Huawei Mobile Services (HMS)

Services HMS (analog Google Play Services) actively cache data, but do not display it in the standard memory manager. To clear:

1. Go to Settings → Applications.
2. Find Huawei Mobile Services (or HMS Core).
3. Tap Storage → Clear cache i Space management → Clear all data.

This will delete temporary files AppGallery, Huawei ID and other services, but will not affect yours accounts.

What happens if you delete files from /data/app?

These folders contain data from installed applications. Deleting them will cause the apps to malfunction (they will stop opening) You can clear the cache here ONLY (*/cache) and ONLY if you are sure of the actions!

4. Transferring data to a memory card or cloud

If the internal memory is full of media files or documents, they can be transferred to microSD or to the cloud. However, Honor there are nuances:

4.1. memory

Not all models Honor support transferring applications to microSD. If the function is available:

1. Insert a memory card (recommended UHS-I Class 10 for speed).
2. Go to Settings → Applications.
3. Select application → Storage → Edit → Map memory.

⚠️ Attention: Transferred applications may work slower, and some (for example, WhatsApp or banking) do not support this function at all.

4.2. Automatic saving of photos and videos to the cloud

Honor offers two cloud services:

Service	Free volume	Features
Huawei Cloud	5 GB	Integration with EMUI, automatic uploading of photos in original quality.
Google Photos	15 GB (shared with Gmail and Drive)	Photo compression up to 16 MP, but cross-platform access.
Yandex Disk	10 GB	Autoloading only through third-party software (for example, AutoSync).

To configure automatic downloading to Huawei Cloud:

1. Open Gallery → Settings → Cloud.
2. Turn on Startup and select networks (Wi-Fi or mobile data).
3. Specify which files to upload (photos, videos, screenshots).

4.3. Manually transferring files to PC

For reliability, create a backup copy on your computer:

1. Connect Honor to PC via USB (select mode File transfer).
2. Copy folders:
   • DCIM (photos and videos),
   • Downloads (downloads),
   • Documents (documents).

Use Huawei HiSuite to backup messages and contacts.

5. Reset to factory settings: when necessary

If the memory is full of unknown files, and the phone slows down even after cleaning, it remains hard reset (reset to factory settings). This is a radical method, but it is guaranteed to return the system to its original state. Before resetting:

• 🔄 Make a backup via HiSuite or manually (see section 4).
• 📝 Write down logins/passwords for accounts (especially Huawei IDif a wallet or purchases are linked).
• 🔋 Charge your phone to at least 50%.

Reset instructions:

1. Go to Settings → System → Reset.
2. Select Reset all settings (or Reset to factory settings).
3. Enter the PIN code or pattern key.
4. Confirm the action.

The process will take 5-10 minutes. After rebooting, the phone will be like new - with free memory and standard settings.

For advanced users willing to work with the command line, there are cleaning options that are not available through the interface. These methods require USB debugging and knowledge of the basics ADB.

6.1 Clearing the cache of all applications via ADB. data-i="252">One command will delete the cache of

One command will clear the cache all applications, including system ones:

adb shell pm trim-caches 256M

This command will limit the cache of all applications to 256 MB For a complete cleanup:

adb shell su -c "rm -rf /data//cache/"

⚠️ Attention: The second command requires root access and may disrupt the operation of some applications!

6.2. Removing unnecessary system applications (debloat)

EMUI contains many pre-installed applications (bloat) that cannot be removed using standard methods. Through ADB this is possible:

1. Connect the phone to the PC and turn on USB Debugging (Settings → About phone → Build number - tap 7 times, then return to Settings → System → For developers).
2. Enter a command to remove unnecessary software (for example, Huawei Browser):

   adb shell pm uninstall --user 0 com.huawei.browser

List of packages safe to remove for Honor:

Application	Package name	Can I delete
Huawei Browser	com.huawei.browser	Yes
Huawei Music	com.huawei.music	Yes
Huawei Video	com.huawei.videoplayer	Yes
Huawei Tips	com.huawei.tips	Yes
Huawei AppMarket	com.huawei.appmarket	No (needed for updates)

6.3. Transferring applications to a memory card via ADB

If there is no transfer option in the interface, it can be forced activated via ADB:

adb shell pm set-install-location 2

After this, all new applications will be installed to microSD to default. To return the setting:

adb shell pm set-install-location 0

What to do if ADB does not see the device?

1. Check if USB debugging is enabled.
2. Install the drivers Huawei HiSuite PC.
3. Try another USB cable (original).
4. Enter the command in ADB: adb kill-server, then adb start-server.

7. Prevention: how to prevent memory from filling up

So that you don’t have to regularly clean your phone, follow these simple rules:

• 📸 Photos and videos: Set up automatic upload to the cloud and delete local copies after checking.
• 📥 Downloads: Empty the folder once a month Downloads —outdated APKs, PDFs and archives accumulate here.
• 🔄 Updates: Delete update files after installation (see section 3.1).
• 🎮 Games: Limit the game cache via Settings → Applications → [Game] → Storage.
• 📊 Monitoring: Use applications like Files by Google or SD Maid to analyze memory.

It is also useful to disable automatic saving of media files in instant messengers:

• V WhatsApp: Settings → Storage → Autoload media → disable for mobile data.
• V Telegram: Settings → Data and memory → Autoload media → select "Never".

FAQ: Frequently asked questions about memory recovery on Honor

Is it possible to increase the internal memory on Honor?

Physically, no. But you can:

• Use microSD as internal memory (on supported models via Settings → Memory → Memory card → Internal memory).
• Transfer some applications to the card (see section 4.1).
• Connect OTG drive (flash drive via adapter).

⚠️ On new models (Honor 50, Magic4) adoptable storage function (using microSD as internal memory) is disabled.

Why, after cleaning, does the memory fill up again within a few days?

Probable reasons:

• 🔄 Auto-updating applications (check in AppGallery or Play Market).
• 📥 Hidden file downloading (for example, TikTok or Instagram caching videos).
• 📁 System logs (see section 3.2).
• 🛠️ Viruses or adware (check your phone via Malwarebytes).

Use SD Maid or Files by Google to monitor "gluttonous" applications.

How to recover deleted files after cleaning?

If the files were recently deleted (within 30 days), try:

1. Check Trash in the application Files or Gallery.
2. Use recovery software: DiskDigger, Recuva (root is required for deep scanning).
3. If the files were in the cloud (Huawei Cloud, Google Photos) - check the web version of the service.

⚠️ After deletion do not write new files to the phone - this will reduce the chances of recovery.

Why does the memory fill up on its own on Honor 8/9/10?

On older models (Honor 8, Honor 9, Honor 10) a bug is common with partition damage /datadue to which the system creates endless error logs Solutions:

1. Update the firmware to the latest version via HiSuite.
2. Reset to factory settings (see section 5).
3. If the problem returns, contact the service center for flashing via eRecovery.

💡 On these models, disabling Huawei ID auto-sync also helps. (Settings → Accounts → Huawei ID → Synchronization).

Is it possible to clear the memory without losing data?

Yes, if you follow the instructions from sections 2-4. However, in the following cases:

• 🔄 System failure (for example, a cyclic reboot),
• 📁 The partition is filled to 100% /data 100% (the phone does not turn on),
• 🛠️ File system damage (errors when reading memory)

- a reset or flashing will be required, which leads to data loss. In such cases, first remove the memory card and connect it to the PC via a card reader to copy important files.
