Owners of brand smartphones Huawei often face a situation when the device starts to work slower, and the memory is filled with incomprehensible files. The system Android over time accumulates a huge amount of temporary data, logs and residual files from remote applications. This not only takes up space, but also loads the processor, reducing the overall performance of the gadget.
Many users are looking for a “magic button” in the form of third-party accelerators, but often these apps themselves become a source of garbage and intrusive advertising. The most reliable and effective way to restore the device to its former speed is manual cleaning. In this article, we will look in detail at how to clean your Android phone of junk manually for free using the example of smartphones Huawei and Honor with a shell EMUI or MagicOS.
The manual method gives you complete control over what exactly is removed. You don't rely on the algorithms of dubious cleaners that can delete important data or, conversely, miss hidden junk. Let's start optimizing your device.
Using the built-in Phone Manager tool
Before delving into complex file systems, it is worth checking the native capabilities of your Huawei. The company has built a powerful tool into the firmware that is often ignored. It's called Phone Manager. This service has access to system partitions that are closed to regular file managers.
Launch the application, which is usually located in the "Tools" folder or on the home screen. Click on the button Cleanup or Optimize. The system will scan and offer to delete application caches, unused installation files APK and remnants of uninstalled apps. This is a safe first stage.
However, the built-in scanner does not always find deeply hidden garbage, such as empty folders or duplicate media files. Therefore, you should not rely only on it. Use it as a base, but proceed to manual cleaning for maximum effect.
Before starting deep cleaning, back up important contacts and photos via Huawei Cloud or Google Drive to avoid accidental data loss.
⚠️ Attention: The built-in manager may suggest deleting “large files”. Check the list carefully before confirming so as not to erase personal videos or documents that you still need.
Clearing the cache and data of specific applications
The most voluminous garbage is generated by instant messengers and social networks. Applications like Telegram, WhatsApp, VK or TikTok save every photo and video you view in a cache. Over time, this folder can grow to several gigabytes.
To clear them manually, go to Settings → Applications → Applications. Find a “heavy” application in the list, for example YouTube. Click on item Memory. Here you will see two buttons: “Clear cache” and “Erase data.”
It is important to understand the difference between these actions. Clearing the cache deletes temporary files (picture previews, video buffer) without affecting your logins and conversations. Erasing data returns the application to the “as after installation” state, removing all settings and authorization.
- 🗑️ The cache can be cleared regularly without fear of losing important information.
- 🔒 Erase data only if you want to completely reset the application settings or solve problems with its operation.
- 📱 Pay special attention browsers (Chrome, Huawei Browser), as they accumulate gigabytes of Internet garbage.
Repeat this procedure for all frequently used apps. This will free up a significant amount of space and can speed up the launch of the applications themselves.
Regularly clearing the messenger cache can free up up to 2-3 GB of memory monthly, which is critical for models with a 64 GB drive.
Manual cleaning through the file manager
For deeper cleaning, you will need access to the file system. Smartphones Huawei have an excellent tool preinstalled - “Files”. Open it and go to the Internal memorysection. Here we will search and delete unnecessary directories manually.
First of all, pay attention to the folder Download (Downloads). Application installers, documents and pictures from the Internet that you have long forgotten about are often downloaded here. Sort the files by size and ruthlessly remove the unnecessary ones.
Next, check the folder DCIM. Inside it there is often a subfolder .thumbnails. This is a hidden folder with thumbnails of your photos and videos. If you have a lot of media files, this cache can take up a lot of space. Deleting the contents of this folder is safe - the system will create it again if necessary, but the space will be freed up instantly.
How to see hidden folders?
In the Files application settings, enable the “Show hidden files and folders” option. This will allow you to find and clear the .thumbnails directory and other system hidden caches.
It's also worth looking into the folder Android → data. Game and application data is stored here. It's normal to delete entire folders from games you've already deleted. But be careful: deleting the active game folder will reset its progress if it is not saved in the cloud.
⚠️ Attention: Never delete files with the extension
.xmlor.inifrom the root directory or system folders if you do not know exactly their purpose. This can lead to system failure.
Search and delete duplicates and empty folders
A common problem is the presence of multiple copies of the same file. This happens when data transfer is unsuccessful or several messengers are running. It takes a long time to manually search for them, but the file manager Huawei has a built-in duplicate search function.
In the “Files” application, click on the three dots in the corner or go to the “Categories” section. Find the "Duplicates" item or use the search by file name. The system will show copies of photos, documents and audio files.
Empty folders are another type of digital waste. They don't take up much space, but they clutter up the memory structure. Some advanced file managers allow you to sort folders by size. Empty ones will have a size 0 B.
| Trash type | Where to look | Deletion security | Approximate volume |
|---|---|---|---|
| Application cache | Settings / Applications | High | 500 MB - 2 GB |
| Downloads | File manager | Medium (check files) | 100 MB - 5 GB |
| Photo thumbnails | DCIM/.thumbnails | High | 100 MB - 1 GB |
| Remains of deleted games | Android/data | High (if the game is deleted) | 1 GB - 10 GB |
Checking these areas regularly will help maintain order. It is not necessary to do this every day, but once a month such a revision is useful.
☑️ Monthly cleaning
Cleaning the system partition and logs
The system Android keeps event logs (logs) that developers need for debugging, but They are of no use to the average user. On smartphones Huawei access to some system logs can be obtained through the developer menu, but it is safer to use special commands or the engineering test menu.
One of the ways is to use the menu ##2846579##. Enter this code in the Phone app as a number. The engineering menu will open. Go to section ProjectMenu → Background Settings → Log Setting. Here you can disable log recording so that they do not accumulate in the future.
It is also worth checking the folder Log or Logs in the root of the internal memory. If there are files there that were created several months ago, you can safely delete them. These are technical reports about failures that are no longer relevant.
Do not forget about the “Trash” in the gallery and file manager. Deleted files often remain there for another 30 days, continuing to take up space. Empty the trash manually to finally free up space.
⚠️ Attention: The engineering menu interface may differ on different versions of EMUI. Do not change the settings in sections related to the radio module or screen calibration if you are not sure of your actions.
Why are logs needed?
Logs (event logs) record all actions of the system and applications. They are useful for finding causes of freezes, but for normal use they only take up space.
Optimizing startup and background processes
The “garbage” in your phone is not only occupied gigabytes, but also clogged RAM. Many applications are added to startup and run in the background, consuming resources. To clean your phone from this “software garbage”, go to settings.
Go to Settings → Applications → Autorun. Here you will see a list of apps that start with the phone. Leave only instant messengers turned on (to receive notifications) and antivirus. Social networks, games and stores can be safely disabled.
Also check the section Battery → Launch applications. Switch control to manual mode for those apps that you do not need to constantly run in the background. This will prevent their hidden operation and the accumulation of temporary data in RAM.
- ⚡ Disabling autorun speeds up the phone's startup.
- 🔋 Saving battery power can reach 15-20% per day.
- 🚀 RAM is freed up for more important tasks.
These actions do not physically delete files, but “cleanse” the system of excess load, which is subjectively perceived as speeding up the work.
Autostart control is the most effective way to prevent the accumulation of software garbage in RAM without the need for constant manual cleaning.
Frequently asked questions (FAQ)
Is it safe to delete the Android/data folder?
You cannot delete the folder itself, since it stores data from all installed applications. However, you can delete specific subfolders inside it that belong to already deleted games or apps. If you delete the active game folder, you will have to download it again.
Why is the space not freed up after cleaning?
You may have cleared only the cache, which is quickly restored, or you have not emptied the trash in the gallery. Also check if cloud synchronization is enabled, which may download files back. Rebooting the phone after cleaning also helps the system correctly recalculate free space.
Do you need to install third-party apps like Clean Master?
No, on modern smartphones Huawei this is not necessary. Built-in tools work more efficiently and safely. Third-party cleaners are often a source of advertising and slow down the system with their background processes.
How often should you clean your phone manually?
It is enough to do a complete manual cleaning once every 1-2 months. Built-in optimization can be run once a week. Frequent full cleaning is not required if you watch what you download.
What should you do if the phone says “Memory full” even though the files have been deleted?
Try rebooting the device. If this does not help, check the folder Lost.dir or system logs. In rare cases, a factory reset is required, but this is an extreme measure that requires a full data backup.
