Detailed guide to clearing RAM on Android Xiaomi Redmi

Many smartphone owners Xiaomi i Redmi periodically encounter a situation when the interface begins to slow down, and applications are unloaded from memory immediately after minimizing. These are classic signs of being overloaded. Unlike permanent memory, where your photos and files are stored, RAM is responsible for running applications at the current time. When it becomes full, the system is forced to urgently reset processes, which causes lags. RAM. Unlike permanent memory, where your photos and files are stored, RAM is responsible for running applications at the current time. When it becomes full, the system is forced to urgently reset processes, which causes lags.

Interface MIUI and its newer version HyperOS have aggressive energy saving algorithms that do not always work correctly from the user’s point of view. Sometimes the system “strangles” necessary apps, and sometimes it allows unnecessary processes to accumulate in the background. Proper cleaning RAM allows you to return the device to its former response speed without the need to reset to factory settings or buy a new gadget.

In this article we will analyze not only standard cleaning methods, but also the hidden capabilities of the system, accessible through the engineering menu. You will learn how to prevent auto-loading of unnecessary services and which developer settings really help, and which only simulate hectic activity.

Standard methods for freeing memory through the interface

The most obvious and safest way is to use the built-in Security application. Despite criticism from advanced users, this tool is deeply integrated into the shell Xiaomi and has rights that are not available to third-party cleaners. When you click the "Cleanup" button, the system terminates background processes that are not critical for the operation of the kernel.

However, it is worth understanding that such cleaning gives only a temporary effect. Modern versions Android are designed to keep as many applications as possible in memory for quick launch. Forcibly closing all apps often leads to the opposite result: the processor has to reload data from the disk the next time it starts, consuming more energy.

For one-time emergency assistance, this method is ideal. Go to the application Security and press the big green button. The system will analyze the occupied space and offer to close applications that consume resources. In some firmware versions, the "Game Acceleration" function is available, which automatically clears RAM before launching heavy projects.

The effectiveness of standard cleaning depends on the model of your device. On budget smartphones with 4 GB of memory, the result will be noticeable immediately, while on flagships with 12 GB the difference may not be obvious, since there is initially a large supply of free memory.

Setting background activity restrictions

A more effective method is fine-tuning the behavior of specific applications. In the settings MIUI you can manually prevent apps from running in the background if you do not need them constantly. This will prevent their accumulation in RAM during the day.

Go to the Settingssection, then select Applications and open All applications. Find the app you want to restrict (for example, a social network or game). Inside the application menu, find the section Activity control or Autostart.

Here you will see a switch Autostart. Disable it for all apps whose real-time notifications are not important to you. Also pay attention to item Work in the background. Setting the "No restrictions" restriction is only necessary for instant messengers, so as not to lose messages. For other apps, it is better to select "Limit background activity."

• 🚫 Disable autostart for stores, browsers and rarely used utilities.
• ⚙️ Check the energy saving settings for each heavy application separately.
• 📱 Do not limit the operation of Google system services, otherwise the phone may not work correctly.

This approach allows the system to decide when to unload the application from memory, but does not allow it to start on its own immediately after turning on the phone. This significantly reduces the load on RAM when the device is idle.

Using the developer menu to manage processes

For users who are ready to delve into system settings, there is a powerful tool - the developer menu. It allows you to control the limit of background processes at the system kernel level. To activate this section, go to Settings → About phone and quickly click 7 times on the item MIUI Version (or Version OS).

After the notification appears that you have become a developer, return to the main settings menu. Scroll down to the section Advanced Settings and select For Developers. Here we are interested in the item Background Process Limit. By default, there is “Standard restriction”.

Changing this setting to "No more than 2 processes" or "No more than 4 processes" will cause the system to aggressively unload applications as soon as you minimize them. data-i="92">there will always be free space for the active task. However, be careful: in this mode, messengers may stop arriving on time, as their processes will be killed instantly. RAM There will always be free space for an active task. However, be careful: with this mode, messengers may stop arriving on time, as their processes will be killed instantly.

⚠️ Attention: Do not set the “No background processes” option. This will lead to constant reboots of system services, rapid battery drain and unstable operation. touch screen.

This menu also has an option Do not save actions. If you enable it, the system will destroy application activity as soon as the user switches to another task. This is an extreme measure, useful only on very old devices with a critical lack of memory.

Hidden setting of the logger buffer size

In the developer menu there is also an item "Logger buffer size". Reducing this value (for example, to 64K or 256K) may slightly free up the memory reserved for system debugging logs, but for the average user the effect will be minimal.

Analysis of memory consumption through engineering. menu

To understand what exactly is "eating" your memory, you can use advanced diagnostic tools. The shell Xiaomi has a hidden engineering menu that can be called up by dialing the number. Enter the code ##6484## or ##4636## in the phone application.

In the menu that opens, select Statistics (Statistics) or Running Services (Running services), if available in your firmware version. A detailed list of processes is displayed here, indicating the occupied space. RAMYou can see not only user applications, but also system ones. daemons.

Pay attention to the process miui.daemon or system_server. If they take up an abnormally large amount of space (more than 1-1.5 GB on a device with 4-6 GB of memory), the system may have experienced an accumulation of errors. In this case, a simple reboot may not help, and deeper intervention will be required.

Process type	Normal consumption	Problem symptom	Action
System services	1.5 - 2.5 GB	More than 3.5 GB	Reboot or reset
MIUI shell	300 - 500 MB	More than 800 MB	Clearing the launcher cache
Google Services	200 - 400 MB	Continuous growth	Reset Google Play settings
Third-party applications	Depends on quantity	Single application > 500 MB	Force stop

Using this data allows you to make informed decisions If you see that a particular application is abnormal. bloated, you should reinstall or delete it.

Clearing cache and temporary files

Although the cache is stored primarily in permanent memory, its excess can indirectly affect the speed of the system and indirectly the RAM, since the system has to index extra files. Regularly clearing the cache is a good hygienic procedure for Android.

You can clear the cache of individual applications through the menu Applicationsby selecting the app and pressing Clear → Clear cache. It is important not to confuse this with the button Clear everything or Reset, which will delete your logins and settings inside the application.

For global cleaning, use the Recovery mode. Turn off your phone, then hold down the power button and volume up button. In the recovery menu, select the language (if available) and the item Wipe Cache. Please note: DO NOT select Wipe Dataor you will lose all your personal files.

• 🗑️ Browser caches often occupy hundreds of megabytes and are safely deleted.
• 📸 The gallery cache may be large if you have watched a lot of videos, but it will recover.
• 📲 It is better to clear the cache of instant messengers (Telegram, WhatsApp) inside the applications themselves so as not to lose media files.

After this procedure, the phone may work a little slower in the first 10-15 minutes, as the system will re-create the necessary temporary files. This is normal behavior.

⚠️ Attention: On new devices with the EROFS file system, the cache partition may be merged with the user partition. In this case, the Wipe Cache item may be missing in recovery. This is not a malfunction.

Radical measures: Resetting and optimizing animations

If software methods do not help and the device continues to slow down, the problem may lie in data fragmentation or an update conflict. In this case, a full reset to factory settings helps. Before doing this, be sure to back up your important data to the cloud Xiaomi Cloud or to your computer.

Another effective trick for visually speeding up work is reducing the scale of animations. This will not free up the physical RAM, but it will reduce the load on the GPU and make transitions between screens instantaneous, creating a feeling of high performance.

Return to the menu For developers. Find three items: "Window Animation", "Transition Animation" and "Animation Duration". By default they are set to 1x. Change them to 0.5x or completely disable them (Disable animation).

Settings -> Additional settings -> For developers ->
Window animation scale: 0.5x
Transition animation scale: 0.5x
Animator duration scale: 0.5x

Visually the interface will become sharper and more responsive On older models of the series Redmi Note this gives a noticeable increase. comfort of use.

Frequently asked questions (FAQ)

Is it true that widgets on the desktop eat up the operating system a lot memory?

Yes, it's true. Each active widget (weather, news, clock) runs a separate process or service that constantly updates data. On devices with 3-4 GB of RAM, deleting unnecessary widgets can free up to 100-200 MB of memory and reduce the load on the processor.

Do I need to use "Memory Expansion" (Virtual) RAM? 5 minutes?

The memory expansion function uses part of the permanent storage for RAM needs. For budget models with 4 GB, this can be a lifesaver, allowing you to keep more applications open. However, the operating speed of such “virtual” memory is lower than real memory. If you have 8 GB or more, it is better to disable this feature to extend the life of the drive.

Why does free memory become low after 5 minutes after clearing the RAM?

This is a feature of the Android architecture. The system tends to fill free memory with a cache of frequently used applications to launch them instantly. Empty RAM is useless RAM. You should only worry if the phone starts to slow down, and not just because the amount of free memory has decreased.

Can a virus consume RAM?

Yes, malware, especially miners or hidden advertising modules, can create background processes that load the system. If you see an unknown process with high resource consumption in the developer menu, check your phone with an antivirus or remove recently installed suspicious applications.
