How to Clean RAM on Xiaomi Redmi 4X

Redmi’s series of smartphones, particularly the Redmi 4X, have earned a reputation as workhorses for their metal body and hardy battery. However, as time passes and applications are updated, even those reliable devices are beginning to experience a shortage of resources, because today’s programs require more space for temporary storage and the device’s RAM quickly fills up.

When RAM runs out of free space, MIUI begins to force the background processes to close, which can lead to interface jerks, delays in switching between applications, and even complete system freeze. The user notices that the phone is slower than in the first days after purchase, and the solution is to clean up RAM correctly and regularly, which does not require superuser rights or deep knowledge of programming.

In this article, we will discuss all the available ways to release RAM on Xiaomi Redmi 4X: from standard shell tools to advanced methods through the developer menu. You will learn to distinguish between system processes and user applications so as not to harm the work of the gadget. Proper resource management will return your device to the same response speed.

Why you should release RAM on Redmi 4X

Many users mistakenly believe that if a phone works, it shouldn't be interfered with. But in the case of Android, and especially the heavy shell MIUI, it's not quite true. RAM is designed to quickly access data from running applications. When you open a browser, messenger or game, they load into RAM. If you just fold an application, it will stay in the background, continuing to consume resources.

The main reason to keep track of memory is to keep the interface running smoothly. When free RAM becomes critically scarce, the CPU has to constantly upload old data to the disk and upload new ones, which causes micro-freezes. On the Redmi 4X, which is equipped with 2 or 3 gigabytes of memory, this effect is especially noticeable when working with heavy social networks or navigators.

Also, crowded RAM directly affects autonomy. Background processes that you can't see can use GPS, internet connection or sensors to drain the battery. Regular cleaning helps extend the life from a single charge, since the processor does not waste energy on servicing unnecessary tasks.

There is also a myth that constant cleaning damages memory. In fact, RAM overwrite cycles are virtually unlimited, unlike flash memory, so active process management is a normal practice for keeping budget and mid-budget smartphones running.

Standard cleaning products in MIUI

The MIUI shell on the Redmi 4X has powerful tools built in to optimize the system. You don't have to download third-party programs that can consume resources on their own. The standard Security app provides all the necessary features for quick cleaning.

To get started, you need to find a green shield icon on your desktop, and that's the control center, and inside you're interested in the memory or cleaning section, and here you're looking at the current state, and you're asking to delete the cache or release the RAM. Pressing the "Clean" button instantly closes the background applications that aren't on the whitelist of exceptions.

It's important to understand the difference between cleaning storage and cleaning RAM. Storage is your photos, videos and installed apps, and RAM is the temporary space to work right now. In the Security app, these features are often combined but work differently. The Clean button in the main menu usually cleans the trash (cache), and for RAM you need to go to the appropriate subsection or use a widget on the desktop.

⚠️ Note: When using the Deep Clean feature in the security application, carefully watch which files are deleted. The system may suggest that you delete old logs or remnants of deleted applications, but sometimes your personal downloads also fall there.

To fine-tune it, you can use the Accelerate widget on your desktop, which typically displays the percentage of memory usage, and clicking on it causes the same cleaning process as you do through the app menu, but it happens in one click, and it's the fastest way to get your phone back responsive in everyday use.

Using a Developer Menu to Manage Memory

For advanced users who want to take full control of the Xiaomi Redmi 4X, there is a hidden developer menu that not only clears memory, but also limits the number of background processes that the system has the right to keep active.

To activate this mode, go to Settings → About Phone and quickly click on the MIUI version number seven times. Once you have become a developer, you can start setting up. New items will appear in the Advanced Settings → For developers.

We're interested in the Applications section, and here you can find the Background Process Limit option, which is the default standard limit, but it can be changed, and choosing the "No More than 2 Processes" or "No Background Processes" option will cause the system to aggressively unload applications from RAM immediately after folding.

Using these settings requires caution. If you set too tight limits, applications will run from scratch every time, which increases their opening time and consumes more CPU power. So after cleaning the memory, it is recommended to return the standard settings, unless you experience a constant shortage of RAM.

Managing Autoboot and Background Processes

One of the main reasons for the clogging of RAM on Redmi 4X Many programs are written into start-up systems to send notifications or update content, even if you don't use them. RAM.

Autoboot management in newer versions of MIUI is often hidden in the Security app under Permissions → Autostart. Here you will see a list of all the programs that start with the phone. Leave only messengers (Telegram, WhatsApp) and alarms on. The rest, including stores, games and news feeds, safely turn off.

Also, it's worth checking application permissions. Some programs require constant back-up to function properly, but most don't. Go to Settings → Apps → All apps, select a suspicious program, and find Battery or Charge Savings. Set No Limits mode for important applications only, and for others, select Limit Background Activity.

⚠️ Warning: Do not disable system services that you do not know the names of (such as Mi Service Framework or Google Play Services) and this can cause your phone to run unstable or alerts from critical services to disappear.

An effective method is also to manually stop heavy applications. If you know that some application (such as a social network) is eating a lot of memory, you can forcibly stop it through the application menu. This will completely unload it from RAM until your next run.

Cleaning cache and temporary files

While cache and RAM are different things, a crowded cache can indirectly affect system speed and RAM management efficiency. When storage is clogged, it is harder for the system to maneuver virtual memory.

The easiest way to use the built-in analyzer is in the Security app, which finds temporary files, installation residues and advertising debris. However, for a deeper cleaning, you can use the built-in file manager. Go to the Analyzer section and delete large files or duplicates that you do not need.

For individual applications, such as browsers or instant messengers, the cache can be cleared individually. Go to Settings → Apps → All apps, select the right one (like Chrome or YouTube) and click Clear → Clear Cache. This action is secure and does not delete your logins or passwords, unlike the “Erase Data” button.

💡

Use Cleanup in your storage settings once a week to prevent the accumulation of gigabytes of temporary files that slow down the system’s indexing.

There are also dedicated cleaning commands available through ADB, but for the average Redmi 4X user, standard tools are enough. The main thing is to do this regularly, without waiting for the phone to start choking from a lack of space.

Third-party utilities and their effectiveness

Google Play has thousands of software-cleaning apps that promise miraculous acceleration. Should they be installed on Redmi 4X? The answer is ambiguous. On the one hand, programs like SD Maid or Files by Google do find hidden garbage better than standard tools.

On the other hand, many Boosters are sitting in the memory, displaying ads and consuming battery power, creating the illusion of working by simply restarting processes that Android will immediately run again, so using third-party software is only justified for finding forgotten files, not for constantly cleaning RAM.

If you do decide to use third-party software, choose time-tested solutions without intrusive advertising. Avoid programs with names like Super RAM Booster Pro that promise to increase memory by many times - this is technically impossible, since the physical volume of RAM is unchanged.

💡

The best cleaner for the Redmi 4X is Xiaomi’s built-in Security app, which has deep system access rights and doesn’t conflict with the MIUI shell.

Remember, no program can add gigabytes of memory, it just helps you manage your resources more efficiently. On a budget device like the Redmi 4X, every megabyte counts, so minimalism in the set of installed software is the best strategy.

Prevention and proper use habits

To make the question of how to clean RAM as rare as possible, it is worth changing your smartphone usage habits. Don't keep dozens of tabs open in your browser unless you need them. Each tab is a separate process that takes up space in RAM.

Regularly update applications and systems. Developers often optimize code to make programs less voracious. However, on older models, new versions sometimes run slower, so watch for feedback from other Redmi 4X users before upgrading heavy apps.

Periodic phone reboots (once every 3-4 days) are a great way to completely clear RAM of system debris and errors that have accumulated over time.

By following these simple rules and periodically maintaining the system, you can significantly extend the comfortable use of your Xiaomi Redmi 4X. The device will delight in the speed of work even years after the release, if you properly manage its limited resources.
