Owners of Huawei smartphones sooner or later face an unpleasant notification that the internal storage is full. This is not just an annoying factor, but a real threat to the stable operation of the device: the launch of applications slows down, artifacts appear on the screen, and the camera may completely refuse to take new photos. In the ecosystem EMUI and the new HarmonyOS mechanisms for accumulating temporary files work differently than on pure Android, which requires a special approach to maintenance.
The artificial intelligence system built into the Huawei shell actively caches data to speed up work, but over time this “smart” cache turns into gigabytes of useless ballast. The user needs to understand the difference between system files, user data, and “garbage” that can be safely deleted without the risk of losing important contacts or correspondence. Proper optimization allows you to return your phone to its former speed even without purchasing a new model.
In this article we will analyze in detail all the available tools: from the built-in phone manager to radical reset methods. You'll learn which folders you can manually delete, how to move heavy media files to the cloud, and why deleting one app might not free up a byte of space. Let's start with the simplest and safest methods that do not require connecting to a computer.
Using the built-in Phone Manager application
The first and most logical step for a Huawei owner is to use a standard optimization tool. Huawei has built into its devices a powerful application Phone Manager (Phone Manager), which automatically scans the system for unnecessary files. You can launch it through the shield-shaped icon on the desktop or by finding it in the settings menu. This application has access to system partitions that are closed to third-party utilities.
When the scan starts, the system analyzes the application cache, remnants of uninstalled apps, installer packages and temporary browser files. Cleaning algorithm Huawei works quite aggressively, offering to delete everything found with one click. However, you should be careful: sometimes the “garbage” list includes thumbnails of images or logs of specific services, which may be needed to diagnose failures in the future.
Particular attention should be paid to the “Cleaning WhatsApp” or “Cleaning messengers” section inside the manager. Messengers take up the lion's share of memory by sending videos and photos. The built-in tool allows you to select specific chats or file types (video only, voice messages only) to delete without affecting important text conversations. This makes it possible to free up several gigabytes by simply removing old postcards and viral videos from general chats.
⚠️ Attention: Before mass clearing through Phone Manager, make sure that you do not delete downloaded offline maps in the navigator or saved playlists in the music service if they are classified as cache by the system.
☑️ Quick cleaning through the Manager
Manual clearing of cache and application data
Automatic tools do not always see the depth of the problem. Some applications, especially social networks like VK, Telegram or Instagram, store gigabytes of data in their private directories, which the manager can ignore or consider important. For deep cleaning, you need to go into the device settings manually. Go to Settings → Applications → Applications.
In the list that opens, find the “heaviest” application. By clicking on it, you will see a button Storage. Here it is critical to distinguish between two functions: “Clear cache” and “Clear data”. The first operation is safe and deletes only temporary files (for example, downloaded news feed images). The second operation resets the application to its factory state: you will be logged out of your account, drafts and local settings will disappear.
Use the data clearing function only for those apps that are ready to be configured again, or that are buggy due to a full storage. For browsers such Chrome or Huawei's built-in browser, clearing data will delete your browsing history and saved passwords if they are not synced to the cloud. Therefore, before such a procedure synchronization is a mandatory preparation step.
⚠️ Attention: The settings menu interface may vary slightly depending on the version of the EMUI or HarmonyOS shell. If you don't find the "Storage" item right away, look for it in the additional menu (three dots in the corner of the screen).
Why does the cache grow so quickly?
Social networking applications save every image and video you view to local memory for instant download when opened again. Over time, this folder can grow to 5-10 GB, even if you did not save the files explicitly.
Analyzing and sorting files in the “Files” application
The standard file manager Files on Huawei smartphones has an excellent categorization function. Instead of wandering through Android's complex folder structure, use the Categories tab. Here the files are divided into clear groups: Videos, Images, Audio, Documents, APK files and Archives. This allows you to instantly identify the main consumers of space.
Users often forget about downloaded application installation files with the extension .apk. After installing the app, these files become useless, but continue to take up space. Go to the "APK" category and ruthlessly delete all the contents if you are sure that the installation is complete. Also check the “Download” folder, where documents from instant messengers and browsers accumulate.
The folder DCIMdeserves special attention. If you actively shoot high-definition video, it can take up tens of gigabytes. In the Files app, you can sort videos by size and remove the heaviest videos that are no longer valuable. In addition, check for the presence of a folder .thumbnails inside DCIM - this is a hidden folder with thumbnails, which sometimes grows to unimaginable sizes due to a software error.
Turn on the display of hidden files in the file manager settings (three dots → Settings → Show hidden files) to find and delete the folder .thumbnails if it takes up too much space.
Don't forget about the folder Bluetooth i ShareMe (formerly HiShare). If you often transfer files over the air, all received documents are saved there. Often in these directories there are old presentations, videos and pictures received six months ago and forgotten by the user.
Management of the Huawei gallery and cloud services
Photos and videos are the main “eater” of memory on a modern smartphone. Huawei Gallery offers convenient tools for working with media, but to fully save space, you need to use cloud technologies. The service Huawei Cloud (or alternatives like Google Photos, if installed) allows you to implement a “cold” storage strategy.
The essence of the method is to upload original photos and videos to the cloud and then delete them from the phone’s internal memory. In the Gallery settings, find the item Synchronization with the cloud. Activate the "Free up space on your device" feature. The system will automatically delete local copies of those files that have already been successfully uploaded to the server, leaving only their reduced previews in the gallery.
When viewing such a photo, it will quickly be downloaded from the Internet in full quality. This is an ideal option for those who have a tariff plan that includes a lot of mobile traffic or have access to Wi-Fi. It's also worth checking out the Recently Deleted album. Files deleted from the gallery go there and are stored for another 30 days, continuing to take up space. Clear this album manually for instant results.
| File type | Medium size | Recommended action |
|---|---|---|
| Photo (JPEG) | 3–8 MB | Upload to the cloud, delete locally |
| Video (4K) | 300–500 MB/min | Transfer to PC or external drive |
| Screenshots | 1–3 MB | Delete old and unnecessary |
| Burst shooting | 50–100 MB (series) | Leave 1-2 best frames, delete the rest |
Working with a microSD memory card
Many Huawei models support installation of memory cards of format NM Card (Nano Memory) or standard microSD. This is the easiest way to expand storage, but Android has its own peculiarities of working with external media. By default, the camera and some applications can save data to internal memory, ignoring the card.
To change this situation, go to the Camera settings. Find the item Save priority and switch it to SD card. Now all new photos and videos will be recorded directly to external media. Also, in the settings of the Voice Recorder and some file managers, you can specify the default save path.
However, it has become more difficult to transfer existing applications to a memory card in modern versions of Android (and EMUI). Many developers prohibit installation of their products on external media for security and speed reasons. You can try to move data through the menu Settings → Memory → Move data to SD card, but the system will only show those files (photos, music, videos) that support transfer.
⚠️ Attention: Memory cards are slower than the internal one flash memory. It is not recommended to install heavy games or active applications on them, as this will lead to freezing of the interface and long loading of levels.
Regular archiving of media files to a memory card or computer is the only way to maintain free space in the long term without deleting the necessary applications.
Radical methods: resetting and formatting
If None of the above methods helped to free up enough space, and the phone continues to signal a critical lack of memory; perhaps the file system is damaged or system garbage has accumulated that is inaccessible to normal cleaning. In this case, extreme measures are considered. The first of them is resetting the settings to the factory state.
This procedure completely deletes all user data, applications and settings, returning the phone to the “store-like” appearance. Before doing this, be sure to create a full backup via the app HiSuite on your computer or via the cloud. To perform a reset, go to Settings → System and updates → Reset → Reset phone settings.
Sometimes the problem lies not in the amount of data, but in logical errors in the file system, when deleted files continue to be listed as busy. In this case, formatting the internal memory (if the phone is rooted) or re-flashing the device via the eRecoverymode can help. To enter this mode, you usually use a combination of the power and volume up keys when the phone is turned off, where you can select the item Wipe data/factory reset.
Combination to enter Recovery:1. Turn off your phone.
2. Press the Volume UP + Power button.
3. Hold until the Huawei logo appears.
Remember that these actions are irreversible without a previously created copy. Use them only when other options have been exhausted. Often, after such a reset, the phone begins to work faster than in the first months after purchase, since the system database cache and media indexing are cleared.
What is the EFS partition?
This is a hidden memory section where unique hardware identifiers (IMEI, MAC address) are stored. Under no circumstances try to format or delete partitions manually through advanced menus if you do not know exactly what they are responsible for - the phone may lose connection.
Frequently asked questions (FAQ)
Why is the space not freed up after deleting applications?
Many applications leave behind folders with data, cache and logs in shared storage. Removing the icon does not erase these files. You need to go to the file manager and manually check the folders with the names of deleted apps, especially in the root of the internal memory or in the Android/data folder.
Is it possible to delete the Android folder?
No, deleting the entire folder Android is absolutely not possible. It stores data from all installed applications. Deleting this folder will reset all apps, losing game progress and settings. You can clean only the contents of subfolders cache inside it, and then with caution.
How to clear memory if the phone does not turn on?
If the phone is stuck on the logo due to full memory, try booting into safe mode (hold down the power button on the lock screen if the system partially boots) and delete the heaviest ones applications. If the system does not boot at all, only connecting to the computer in MTP mode (if you're lucky) or a full reset via the Recovery menu using the buttons will help.
Does full memory affect Internet speed?
Indirectly - yes. When the internal memory is full, the system does not have enough space for temporary clipboard files and browser cache. This can lead to pages loading more slowly and the video stream being constantly buffered, since the device has nowhere to record the incoming data stream.
Is it worth using third-party apps like Clean Master?
On modern Huawei smartphones this is not necessary. The built-in Phone Manager works more efficiently and securely. Third-party “cleaners” themselves often consume a lot of resources, show intrusive advertising and can aggressively delete necessary files, disrupting the operation of stable applications.
