Smartphone Honor 9, despite its advanced age, continues to be a popular device due to its balanced characteristics and high-quality build. However, over time, any operating system Android accumulates temporary files that can significantly slow down the operation of the gadget. Users often encounter a situation where the interface begins to slow down, and applications take longer to launch than usual.
The main reason for such problems is overcrowded application cache system services. This is temporary data that is created to speed up access to frequently used information, but over time it becomes outdated and takes up valuable space in internal memory. Regularly clearing this data is a simple and effective way to restore your device to its former speed.
In this article we will look in detail at how to clear the cache on Honor 9 various methods: from standard settings to using the engineering menu. You will learn which files can be deleted without fear of losing important data, and which files should absolutely not be touched. We will also look at the nuances of the shell EMUIinstalled on this model.
Understanding the structure of the cache in the Android system
Before you start deleting files, you need to clearly understand what exactly we are going to erase. Application cache is a set of temporary data, such as image thumbnails, saved web page scripts or intermediate game files. This data is not critical for the operation of the app, since it can be generated anew if necessary.
However, there is a concept system cachethat includes deeper settings and logs of the operating environment. Clearing the system cache is often required after a firmware update or when critical boot errors occur. It is important not to confuse clearing the cache with a factory reset, which deletes all user data.
On a device Honor 9 running a shell EMUI the structure of storing temporary files has its own characteristics. The system automatically allocates memory, but sometimes the algorithms fail and old files are not deleted correctly. It is in such cases that manual user intervention is required to free up space.
⚠️ Attention: Clearing the cache of specific applications (for example, instant messengers) may lead to temporary loss of chat history or media files if they are not saved in the cloud. Always check your backup settings before the procedure.
Before mass clearing the cache, check which applications are taking up the most space in the “Storage” section. Often one “heavy” messenger consumes gigabytes of temporary data.
Clearing the cache of individual applications through settings
The safest and recommended way to free up memory is to work with each application separately. This method allows you to control the process and delete data only from those apps that really take up a lot of space. First, you need to go to the main settings menu of your smartphone.
In the menu, find the section Applications or Application Manager. From the list of all installed apps, select the one you want to optimize. Often the leaders in memory consumption are social networks, browsers and navigators. After selecting an application, a screen with detailed information about it will open.
On the application information screen, find the button Memory or Storage. By clicking on it, you will see two options: “Clear data” and “Clear cache”. We are interested in the second option. Clicking this button will delete temporary files without affecting your logins, passwords and basic app settings.
- 📱 Go to
Settings → Applicationsto access the list of apps. - 🗑️ Use the Clear cachebutton rather than “Clear data” to save progress.
- 🔄 Repeat the procedure for the most “heavy” applications: YouTube, Instagram, Chrome.
- ⏳ Wait until the process completes, the memory indicator should decrease.
If you want to speed up the process, you can use the built-in optimization tool. In the settings menu there is often an item Memorywhere the system itself offers to clear unnecessary files. However, a manual check gives a more accurate result, since you see what exactly is being deleted.
☑️ Check before clearing the application
Using the built-in phone manager
Company Huawei and brand Honor equip their smartphones with a powerful built-in tool called Phone Manager. This application is pre-installed on the system and provides a comprehensive approach to device maintenance, including cleaning up garbage.
Launch the icon Phone Manager on the desktop. In the main menu you will see a large “Cleaning” button or a broom icon. When pressed, the system will automatically scan the internal memory for temporary files, remnants of deleted apps and duplicates.
After the scan is completed, you will be prompted to delete the files found. The system will show the total amount of freed space. Unlike manual cleaning, this method is faster but less detailed. You can click on the "Cache Files" category to see a more detailed list before confirming deletion.
| File type | Description | Deletion security | Volume (example) |
|---|---|---|---|
| Cache applications | Temporary app data | Safe | 100 MB - 2 GB |
| Residual files | Folders from deleted games | Safe | 50 MB - 500 MB |
| Junk files | Advertising garbage, logs | Safe | 10 MB - 100 MB |
| Large files | Video, archives, images | Requires verification | 1 GB - 10 GB |
Using a full-time dispatcher is preferable for most users, since the algorithms EMUI know the structure of the system well and will not remove anything unnecessary. Regular use of this function once a week will help keep your smartphone in good shape.
Clearing the cache through Recovery mode
Sometimes there is a situation when the smartphone freezes, does not boot to the desktop, or is extremely unstable. In such cases, normal cleaning through settings is not possible. The mode Recoverycomes to the rescue, which allows you to clear the system cache at a deep level.
To enter this mode, you must completely turn off the smartphone Honor 9. Then hold down the Volume Up button and the Power button at the same time. Hold them until the logo appears Honor, then release the power button, but continue to hold the volume until the recovery menu appears.
In the menu Recovery control is carried out with the volume buttons (up and down) and the power button (select). You need to find the item Wipe cache partition. Be extremely careful: do not confuse this item with Wipe data/factory reset, which will delete all your personal data.
⚠️ Attention: In Recovery mode, the touch screen does not work. Navigation is carried out only by physical volume and power buttons. Do not press the reset button accidentally.
After selecting the clear cache option, the system will ask for confirmation. Select Yes and wait for the process to complete. When finished, select the option Reboot system now to restart your smartphone. The first startup after such a procedure may take longer than usual.
What to do if the Recovery menu does not appear?
If the button combination does not work, try connecting the smartphone to the computer with a cable before turning it on. On some versions of EMUI firmware, entering recovery mode is only possible if there is a USB connection.
Third-party utilities for deep cleaning
If the built-in tools are not enough, you can turn to specialized software from the store Google Play. There are many applications, such as CCleaner, Clean Master or Files by Googlethat offer advanced functionality for memory analysis.
Such utilities are able to find hidden caches that the standard manager does not see. They can also analyze your browser history, clipboard, and empty folders. However, it is worth remembering that installing another application itself consumes device resources.
When using third-party software, be sure to grant it the necessary permissions to access files. Without this, the app will not be able to correctly scan the internal storage. It is recommended to choose applications from well-known developers with a high rating.
- 🛡️ Download utilities only from the official store Google Play.
- ⚙️ Set up automatic cleaning in the application schedule.
- 🚫 Avoid “aggressive” cleaners that close background processes.
- 📊 Use the analysis function to understand the structure of the occupied space.
It is important to understand that third-party apps do not provide a magical performance boost if the problem is physical memory wear or an outdated processor. They only help maintain the hygiene of the file system.
Third-party applications are useful for one-time deep cleaning, but for daily use it is better to rely on the built-in Honor manager so as not to waste the battery with unnecessary processes.
Prevention and optimization of Honor 9
Clearing the cache is therapeutic measure, but it is better to engage in prevention so that the problem does not return too often. On a smartphone Honor 9 you can disable the automatic saving of some temporary data in the settings of specific applications, for example, in the browser.
Regularly delete applications that you do not use. We often forget about apps installed “just in case,” but they continue to run in the background and generate cache. It is also useful to periodically reboot your smartphone, since when you reboot, some temporary files are cleared automatically.
Keep an eye on system updates EMUI. Engineers Huawei constantly release patches that optimize memory management and correct errors that lead to cache growth. The current firmware version guarantees the most efficient resource management.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of the installed EMUI firmware. If you do not find the described item, look for a similar one in the adjacent settings sections.
Do not fill the internal memory to capacity. The Android system needs free space (at least 10-15% of the total volume) for the caching mechanisms and_swap_files to work correctly. If the memory is completely full, the phone will slow down even after cleaning.
Enable the “Smart Cleaning” function in the phone manager, if it is available in your firmware version. It will automatically delete screenshots and downloaded files older than 30 days.
Frequently asked questions (FAQ)
Will my messages on WhatsApp be deleted when clearing the cache?
No, when you click the “Clear cache” button in the application settings, your messages, photos and contacts will be saved. Only temporary files, such as avatar thumbnails or temporary copies of media files, will be deleted. However, if you click “Clear data”, the entire correspondence history will be deleted without the possibility of recovery.
Why does the cache quickly fill up again after clearing?
This is normal behavior of the operating system Android. Applications create a cache in order to work faster and not download the same data from the Internet or the processor repeatedly. If you actively use social networks or browse the Internet, the cache will accumulate again within a few days.
Is it possible to clear the cache of all applications with one button?
In the standard settings Honor 9 there is no such function, you need to go into each application separately. However, the built-in “Phone Manager” allows you to clear the bulk of garbage with one button. Third-party applications also offer a bulk cache clearing function.
Does clearing the cache affect the charging speed of a smartphone?
Clearing the cache does not directly affect the charging speed of the battery. However, if the phone was very slow due to full memory and the processor was working at its limit, then after optimization the device may heat up less, which will indirectly have a positive effect on the charging process.
Is it safe to use Recovery mode for a beginner?
Using Recovery mode is safe if you strictly follow the instructions and select only the item Wipe cache partition. The main danger is accidentally selecting the factory reset option, so be careful when navigating with the volume buttons.
