Modern smartphones of the brand ASUS have powerful hardware and a well-thought-out shell ZenUI, but over time, even the most productive devices begin to work slower. The main reason for slow performance is that the RAM and internal memory are full of unnecessary files, application caches, and system junk. Users often encounter messages about lack of space or sudden app crashes, which significantly spoils the experience of using the gadget.
The process of freeing up resources on devices of this brand has its own nuances associated with proprietary utilities and the specifics of the operating system. Android. In this article, we will analyze in detail all the available optimization methods: from standard cleaning tools to advanced techniques for managing background processes. You will learn which files can be deleted without fear of losing important data, and which files should absolutely not be touched.
Regular system maintenance can extend the battery life and keep the interface running smoothly for several years. You shouldn’t wait until your phone freezes completely—it’s better to take preventive measures in advance. Below are step-by-step action algorithms that will help restore your ASUS ZenFone or ROG Phone former speed.
Diagnostics of the current state of the system
Before taking radical measures, you need to understand what exactly is consuming the resources of your device. Built-in monitoring tools allow you to see memory allocation in real time. Go to the section Settings → Memoryto get summary information about the occupied space.
The system will show details by category: applications, images, video, audio, etc. Pay attention to the “Other” or “System files” item, which often swells to obscene sizes due to indexing errors or log accumulation. RAM also requires attention, since full RAM leads to constant reboots of active tabs in the browser.
⚠️ Attention: If you see that the “Other” category takes up more than 20% of the total volume, this may indicate a problem with the file system or the presence of hidden temporary files that are not deleted by standard methods.
For a more in-depth analysis, you can use the developer mode, where advanced memory usage graphs are available. You can activate it by clicking seven times on the build number in the menu About the phone. This will give you access to statistics of processes running in the background right now.
Using the proprietary Cleaner utility
The company ASUS preinstalls a special application on its devices Phone Master (or simply Cleaner in new versions firmware). This tool is the first line of defense against digital waste and works more efficiently than third-party analogues thanks to deep integration into the system.
Launch the application and press the large scan button. The utility will automatically find residual files from deleted apps, empty folders and duplicate contacts. The operation algorithm is designed so as not to affect important user data, but before mass deletion it is better to check the list of found garbage again.
- 🗑️ Clearing the application cache - deletes temporary files, speeding up the launch of apps.
- 📦 Startup control - prevents unnecessary apps from starting with the phone.
- 🛡️ Anti-virus scanning - checks the system for malware that can secretly consume resources.
Particular attention should be paid to the “CPU Cooling” function, which often comes bundled with memory cleaning. It forcibly closes heavy processes, relieving the processor and RAM. This is especially true for gaming models of the series ROG, where throttling can begin due to background activity.
Set up automatic cleaning in Phone Master at night when the phone is not in use, so that you can start with a “clean” system every morning.
Manual clearing of cache and application data
Automatic cleaners do not always cope with heavy applications, such as social networks or instant messengers. For example, Telegram or Viber can store gigabytes of media files in their internal cache, which is not always correctly identified by the system as “garbage”. This requires manual intervention through the settings.
Go to the menu Settings → Applications → All applications. Choose the app that takes up the most space (usually browsers or social networks). Inside the application card, you will see two important buttons: “Clear cache” and “Clear data”. The first deletes temporary files, the second resets the application to its factory state, deleting logins and settings.
| Action | What is being deleted | Risk of data loss | Recommended frequency |
|---|---|---|---|
| Cache clearing | Temporary files, thumbnails | No | Once a week |
| Data clearing | Accounts, settings, databases | High | Only in case of failures |
| Removing updates | Latest versions of system applications | Medium | If there is not enough space |
| Forced stop | Current process in RAM | No | As needed |
It is important to distinguish between the concepts of cache and data. If you clear your messenger data, you will have to re-enter your phone number and verification code. Therefore, use this feature with caution and first back up your chats to the cloud.
⚠️ Warning: Do not clear data from system applications such as Phone, Contacts, or Settings unless you are sure of what you are doing. This may lead to incorrect operation of the interface or loss of the phone book.
Managing files and media content
The bulk of the built-in memory on smartphones ASUS usually taken up by photos, videos and downloaded files. The standard file manager allows you to quickly find and delete large objects. Sort files by size to identify “heavyweights” that you haven’t opened for a long time.
A special category consists of folders of downloads from browsers and documents received through instant messengers. Often installation files accumulate there .apk, which have already been installed but forgotten by the user. Deleting them is safe and instantly frees up space.
- 📸 Check the folder
DCIM/.thumbnails—gallery thumbnails are stored there, which can grow up to gigabytes. - 📥 Clean the folder
Downloadfrom old documents and installers. - 🎵 Delete music that you have already transferred to your computer or cloud storage.
For owners of models without a memory card slot, it is critical to set up synchronization with Google Photos or other cloud services. The “Free up space” feature in Google Photos automatically deletes pictures from the device that have already been successfully uploaded to the cloud.
Hidden folders in ASUS
Some ASUS models have a hidden folder.nomedia, the creation of which in the directory with media files prevents the system from scanning it for the gallery. This is useful for storing private files, but does not save space.
Optimizing random access memory (RAM)
Unlike internal memory, RAM is cleared automatically by the system when there is a lack of resources, but this mechanism does not always work quickly enough. On devices with the shell ZenUI there is a function for blocking applications in memory, which prevents them from being unloaded.
To force free up RAM, call up the recent applications menu (square navigation button) and click the “Close all” button. If you have game acceleration or performance settings enabled, the system may aggressively hold up certain processes. Disable unnecessary services in the menu Applications → Special access → Access to notifications.
Google Play Services Sometimes they can consume an abnormally large amount of RAM due to synchronization errors. Rebooting the device in this case is the most effective way to reset memory counters and end frozen processes.
Regularly rebooting the smartphone (at least once every 3-4 days) is more effective than any cleaners for freeing up RAM and eliminating minor software glitches.
Radical measures: Reset to factory settings
If none of the above methods helped and the phone continues to slow down, the last option remains - a full reset. This procedure will return the device to its “out of the box” state, removing absolutely all user data, applications and settings.
Before starting the procedure, be sure to create a full backup of your data. Use the built-in backup tool ASUS or Google account. After the reset, you will have to set up your phone again, enter Wi-Fi passwords and install applications, but performance will be restored to 100%.
To perform a reset, go to Settings → Backup and reset → Reset settings. Confirm by entering your screen unlock PIN. The process will take from 5 to 15 minutes depending on the amount of memory and speed of the drive.
⚠️ Attention: Before performing a reset, make sure that the battery level is at least 50%. Interrupting the process by turning off the phone can damage the software and turn the device into a “brick.”
☑️ Preparing for a full reset
Prevention and good habits
To prevent the problem of lack of memory from returning in a month, you should change your smartphone usage habits. Do not install applications “in reserve” and regularly audit installed apps. Delete games that you have not played for more than two weeks.
Disable automatic saving of media files to the gallery for all instant messengers. In the settings WhatsApp or Telegram you can prohibit saving received pictures and videos to internal memory, leaving them available only within the chat.
Use the “Adaptive Brightness” and “Energy Saving” functions, which indirectly affect the operation of background processes. Less stress on the system means fewer temporary files and less need for deep cleaning.
Install the memory cleaning widget on your home screen for quick access. One tap on it will allow you to close all background applications before launching a heavy game or camera.
Frequently asked questions (FAQ)
Is it possible to delete system applications on ASUS to free up space?
Without receiving root access it is impossible to completely remove system applications, you can only turn them off. Disabling hides the application from the menu and prevents it from launching, which frees up RAM, but saves almost no space in the internal storage. Inexperienced users are not recommended to try to remove system components via ADB, as this may disrupt the operation of the phone.
Why does the memory quickly fill up again after cleaning?
This is normal behavior for the operating system Android. Applications constantly create new cache files to speed up their work (pictures, web pages). If the memory fills up abnormally quickly (within a few hours), check whether any application is running in an error loop, constantly recording logs.
Does memory fullness affect Internet speed?
Memory does not have a direct effect on the connection speed, however, if there is a critical lack of space (less than 100 MB free), the system begins to work unstable. This can lead to dropped connections, browser freezes and incorrect loading of pages, which the user perceives as a problem with the Internet.
How to transfer applications to a memory card on ASUS?
In modern versions of Android, support for transferring applications to an SD card is limited to the developers of the applications themselves. If the app supports this function, the “Change” button next to the storage will be active in the menu Settings → Applications . Otherwise, only photos, videos and documents can be transferred to the card.
