How to clear the cache on Honor 20 Pro: acceleration and optimization

Modern smartphones, including flagship models like Honor 20 Pro, begin to work slower over time due to the accumulation of temporary files. This data, known as cache, is created by applications and the system to speed up access to frequently used information, but too much of it can cause crashes. Understanding how to effectively manage this data is a key skill for any Android device owner.

Many users mistakenly believe that deleting the cache will lead to the loss of personal photos or contacts, but this is not the case. Temporary files do not contain your personal information, but only speed up the loading of interface elements and applications. Regular cleaning can free up gigabytes of space and eliminate errors that occur during software operation.

In this article we will take a detailed look at the various cleaning methods available on EMUI and newer versions of the shell Magic UI. You'll learn how to safely remove system junk, clear app-specific data, and even perform a deep clean through the recovery menu. This will help return your Honor 20 Pro original response speed.

Why you need to clear the cache on your smartphone

The main function of caching is to reduce data loading time. When you open an application or web page, the system saves its elements in Device memory. When these resources are accessed again, the phone reads the data from fast local storage rather than re-downloading it from the network or disk. However, over time, these files can become damaged or take up critical space.

If the cache is full or contains errors, you may experience interface freezes, apps closing spontaneously, or graphics displaying incorrectly. This is especially true for social networks and instant messengers, which store huge volumes of media files. Clearing helps reset these states and make applications work again as they did after installation.

⚠️ Note: Clearing the cache does not delete your logins, passwords, or game progress. However, clearing the application's "data" (not to be confused with the cache) will completely reset the app to the "as after installation" state.

In addition, freeing up space on the internal storage has a positive effect on overall system performance. Android uses free space for virtual memory and temporary operations. When the disk is full, the writing and reading speed drops, which makes use Honor 20 Pro less comfortable.

Using the built-in phone manager

The safest and easiest way to remove garbage is to use standard system tools. The shell installed on Honor 20 Prohas a powerful built-in optimization tool. It scans the device for unnecessary files, residual software and a large amount of temporary data.

To get started, find an application called Optimization or Phone Manageron the desktop or in the "Tools" folder. Launch it and click the button Cleaning. The system will automatically analyze the memory status and suggest deleting files that are considered safe to delete. This method is ideal for beginners, as it eliminates the risk of deleting important system components.

Inside the optimization menu, the “Storage” section is often available, where you can see in detail what exactly is taking up space. Categories are displayed here: images, videos, documents and, of course, application cache. By clicking on the "Cache" category, you will see a list of apps sorted by the amount of temporary data occupied.

It is important to note that the built-in tool does not always delete the cache completely, leaving some files to speed up restart. This is normal system behavior aimed at balancing speed and free space. For deeper cleaning, manual intervention in the settings of each application will be required.

Manually clearing the cache of specific applications

If the problem with operation concerns only one app, for example YouTube or Instagram, there is no need to clean the entire phone. You can specifically delete temporary files specifically for this service. This is especially useful if the application constantly crashes or does not load content.

To perform this operation, go to Settings your Honor 20 Promenu. Find the section Applications and select Applications (or "Application Management"). Find the desired app in the list that opens. If the list is too large, use the search at the top of the screen.

After opening the application card, find the section Memory or Storage. Here you will see two main buttons: "Clear cache" and "Reset". Click only on the first one. The size of the cache can vary from several kilobytes to several gigabytes, depending on the activity of use.

Application type	Cache size (approximate)	Frequency of cleaning	Impact on data
Social networks	500 MB - 2 GB	Once a week	Safe
Browsers	100 MB - 500 MB	Once a month	Logins may disappear
Navigators	200 MB - 1 GB	As needed	Offline cards will fly off
Messengers	1 GB - 5 GB+	Rarely (via settings)	Media may disappear

After clearing the cache, the application will start a little longer than usual, since it will have to download the necessary resources again. However, this often solves problems with interface freezing and authorization errors. Regular manual cleaning of heavy applications helps to keep Honor 20 Pro in good shape.

Cleaning through the Recovery menu

For more advanced users, there is a method for clearing the system cache through the menu Recovery. This method deletes temporary files of the operating system itself that are not accessible through normal settings. This often helps after updating the firmware or in case of strange system errors.

To enter this mode, you must completely turn off the smartphone. Then press the Volume Up and Powerbuttons simultaneously. Hold them until the logo Honorappears, then release the Power button while continuing to hold the Volume down. After a few seconds, the recovery menu will open.

What to do if the Recovery menu does not open?

If the standard button combination does not work, try connecting the phone to the computer via a USB cable before turning it on. Also, some firmware versions require double-clicking the volume button. If all else fails, this section of the menu may not be accessible without an unlocked bootloader.

In the menu, navigation is carried out using the volume buttons, and selection is made using the power button. Find the item Wipe cache partition. Please note: DO NOT select the item Wipe data/factory resetas this will completely delete all your data and reset the phone to factory settings.

⚠️ Attention: In new versions of Android (starting from 11 and above), access to the cache partition in Recovery is often hidden or deleted by developers. If you do not see the "Wipe cache partition" item, it means that your software version does not support this method. Do not try to experiment with other menu items.

After confirming the action, the system will clear the partition /cache. This process only takes a few seconds. When finished, select Reboot system now to reboot. The first launch after such a procedure may take longer than usual.

Clearing the cache in the Huawei and Chrome browser

Web browsers are one of the main generators of junk files. They save copies of visited pages, images and scripts to speed up sites reloading. On Honor 20 Pro most often used Chrome or the built-in browser Huawei Browser.

To clear in Chrome, click on the three dots in the upper right corner, select History, then New tab (or go to history settings). Select Clear history. In the window that appears, make sure that the checkbox next to “Images and other files saved in the cache” is checked. Dates can be selected "All time".

Built-in browser Huawei is cleared in the same way. Go to Settings (three stripes or dots), select Privacy or Clear data. Here you can also delete cookies, which will require re-authorization on sites, but will clear traces of your stay on the network.

Regularly clearing the browser cache is useful if pages are not displaying correctly or you see an old version of the site after updating its design. However, doing this every day does not make sense, since the browser will have to download all resources again, which will increase traffic consumption.

Third-party utilities for cleaning memory

There are many applications in the Play Market that promise to speed up the phone. Popular options include Clean Master, CCleaner or Files by Google. They are able to find duplicate files, residual software and deep caches that standard tools do not see.

However, the use of such apps on modern smartphones, such as Honor 20 Pro, is often redundant. The Android system has already learned how to efficiently manage memory itself. Third-party “cleaners” can even slow down your work by constantly running in the background and consuming processor resources.

If you still decide to use third-party software, choose proven solutions from well-known developers. Avoid apps with aggressive advertising and questionable permissions. The best choice remains the application Files from Google, which safely analyzes the storage.

• 📂 Files by Google - official application, safely removes garbage and duplicates.
• 🧹 SD Maid - a powerful tool for advanced users, finds the "tails" of deleted apps.
• 🚀 CCleaner - a classic of the genre, but requires careful settings so as not to clean unnecessary things.

The main principle when using third-party software is not to install more than one cleaner at a time. They can conflict with each other and block the system. Remember that no app will make your phone faster than it was when you bought it, but it will help you keep your files organized.

⚠️ Warning: Be careful with the "RAM Boost" features in third-party applications. Forcibly closing background processes on Android often results in the system immediately launching them again, using up even more battery power.

Frequently asked questions (FAQ)

Will my WhatsApp correspondence be deleted when clearing the cache?

No, correspondence, photos and videos saved in the gallery will remain in place. Clearing the cache will only affect temporary files that speed up the operation of the application, for example, avatar thumbnails or temporary copies of viewed statuses.

How often should you clear the cache on Honor 20 Pro?

There is no need to specially plan cleaning. It’s enough to do this as needed: if the phone starts to work slower, you’ve run out of space, or a specific application is behaving inappropriately. Once a month is quite a sufficient frequency for prevention.

Why does the cache fill up again after clearing?

This is normal system behavior. Apps create a cache every time you use them to help them run faster. If the cache were not created anew, the phone would work slower, constantly downloading data from the Internet.

Is it possible to clear the cache of all applications at once?

With standard Android tools, you cannot massively clear the cache of all applications with one button (the function was removed in older versions of Android). However, the built-in manager of the Honor phone allows you to clear a significant part of the system garbage with one click.
