How to increase RAM on Xiaomi Android: methods and risks

Many Xiaomi smartphone owners sooner or later face a shortage of RAM, especially on budget models, where the standard 4 or 6 GB becomes insufficient for today's heavy applications and games. When the system begins aggressively unloading background processes or games restart every time you switch, the user thinks about how to increase RAM on Xiaomi Android without buying a new device. In fact, there are software methods to expand the available memory pool or optimize its use, although they have their own technical limitations.

Xiaomi’s current smartphones, which run on MIUI and HyperOS shells, offer built-in resource management tools that are often hidden from the eyes of the average user. Virtual memory expansion has become the industry standard, allowing you to reserve some of the fast internal storage for the needs of the system. However, it is important to understand that physically adding new memory chips is not software-enabled, it is only about correctly redistributing existing resources or emulating additional volumes.

In this article, we will take a look at all the ways to increase RAM, from regular MIUI functions to advanced settings through developer mode. You will learn how Memory Extension technology works, whether to use third-party applications to create a paging file, and what real risks there is interference with system parameters. We will also analyze why increasing the numbers in the settings does not always lead to the desired performance increase.

Built-in memory expansion function in MIUI and HyperOS

Starting with certain versions of MIUI 12.5 firmware and all current HyperOS builds, Xiaomi has implemented a native RAM extension feature, known as Memory Extension, which takes a portion of free RAM (ROM) and uses it as virtual RAM (RAM), which allows the system to keep more applications in the background without unloading them completely, which is especially true for models with 4 or 6 GB of physical memory.

To activate this feature, you need to go to the Settings menu → Advanced Settings → Expansion of memory. Here the system will suggest selecting the amount of memory added, which usually varies from 2 to 4 GB depending on the smartphone model. After selecting the size, you will need to restart the device to take effect and the system redistributes the address space.

While convenient, the technology has its nuances: The speed of the built-in drive, even if it is a fast UFS 3.1, is still significantly lower than the speed of real LPDDR5 RAM. So, when you use virtual extensions actively, you can see a slight increase in latency or micro-freeze in the interface, as the system has to turn to slower storage more often.

⚠️ Warning: Constantly recording and overwriting large amounts of data in virtual RAM mode can theoretically speed up wear of a smartphone’s flash memory, although modern memory controllers are good at load distribution.

It's also worth noting that this feature isn't available on all models, and it's usually present in mid-budget and flagship segments, and some entry-level innovations, and if you don't find it in the settings, your model doesn't hardware or software support native extensions from the manufacturer.

Developer settings to optimize memory

If there is not enough or no standard memory extension, you can try to optimize the use of existing resources through the hidden developer menu. This section contains parameters that affect how the system manages background processes and how much resources each application allocates. To enter this section, go to Settings → About phone and quickly click 7-10 times on the MIUI version or OS version.

Once the developer menu is activated (the corresponding notification will appear), go to Settings → Advanced Settings → Developer. Here we are interested in the section related to background processes. Find the Background Process Limit and make sure that there is a value of Standard Limit or No Limits. Setting artificial limits can lead to more aggressive closure of applications, which will create the illusion of a lack of memory.

Another important parameter is the tuning of animations. While it doesn't add physically bytes to RAM, reducing the load on the GPU and rendering system frees up resources for other tasks.

• 🎨 The scale of window animation - set 0.5x or turn it off.
• 🎨 The scale of transition animations - set 0.5x or turn it off.
• 🎨 Duration of animation - set 0.5x or turn it off.

Also on the developer menu, you can find a parameter related to the aggressiveness of closing background applications. Some versions of MIUI firmware include Aggressive Apps Heuristics or similar. Disabling excessive aggression in memory management can help keep the desired applications in RAM longer than the default system does.

Use of the swap file through Root rights

For advanced users who are ready to take full control of the system, there is a method for creating a full swap file based on internal memory or SD-This method requires the presence of Root rights (superuser rights), the receipt of which automatically deprives of guarantees and may disrupt the operation of banking applications and services Google Pay (Mir Pay).

The method is to create a special file on the disk, which the system will perceive as an extension of RAM. To implement this method, the most common use of specialized applications such as SWAP No Root (does not work on all models) or more powerful tools like Kernel Adiutor with access rights.

1. Getting Root-rights through unlocking the bootloader and installing Magisk.
2. Installation of an application for managing a Swap file.
3. Select the size of the paging file (usually 1 to 4 GB).
4. Activation and reboot of the device.

The main risk here is read/write speed. If you create a paging file on a normal low-speed microSD card, the phone will start to work noticeably slower. Slow-drive virtual memory creates a bottleneck, causing the processor to sit idle waiting for data. In addition, an incorrect Swap configuration can lead to a cyclic reboot of the device.

Third-party applications for cleaning and managing RAM

There are hundreds of apps on the Google Play Store that promise to “boost” memory and speed up your phone, but it’s important to understand how they work: they don’t create new memory, they just force the background processes to close, freeing up the current amount of RAM. Popular examples include Clean Master, CCleaner, or built-in counterparts.

Using these accelerators often backfires. Android is designed to keep frequently used apps in memory for quick launch. When a third-party janitor forcibly closes them, the system has to reboot those apps from scratch, which consumes more CPU and battery power than if they were just hanging in the background. This phenomenon is known as the memory cleaner paradox.

However, there are more advanced tools that can analyze memory consumption for specific applications and make recommendations. For example, the 3C All-in-One Toolbox app allows you to fine-tune process priorities in detail, but even then, regular manual memory cleaning is not an effective way to improve long-term performance.

⚠️ Warning: Avoid apps that promise to “up to 200 percent RAM” without root rights, most often a marketing ploy that hides intrusive ads or miners that will only put more stress on your CPU.

Comparison of methods of memory expansion

To make it easier for you to choose the right method, we have prepared a comparative table of the main ways to increase the available RAM on Xiaomi devices, each of which has its advantages and disadvantages depending on the phone model and user skills.

As you can see from the table, the safest and most balanced option for most users is to use the standard Memory Extension feature, if it is available in your firmware version, which provides predictable results without having to climb into system files.

💡

Before enabling any memory expansion method, be sure to back up your data via Mi Cloud or locally to your computer, which will allow you to recover information in the event of a system failure.

The effect of memory type on performance

It is important to distinguish between memory types, as the effectiveness of any manipulation depends on it. Modern Xiaomi smartphones use memory standards LPDDR4X and LPDDR5. LPDDR5 can run up to 6400 Mbps and higher, while even fast UFS 3.1 drives used for virtual memory have other characteristics of the read speed of random blocks.

When you add memory software, you're actually mixing the slow component with the fast one. The system tries to balance the load, but in scenarios that require high response rates (e.g., heavy response times). 3D-games like Genshin Impact or PUBG Mobile, relying on virtual memory can cause drawdown FPS. Physical RAM cannot be replaced with a software crutch without loss of speed.

However, for everyday tasks — social networks, multi-tab browsers, instant messengers — virtual extension works perfectly, preventing applications from being downloaded, allowing them to return instantly to them, which is subjectively perceived as an improvement in multitasking.

💡

Virtual memory is ideal for multitasking (many open applications), but does not add power to heavy computing or gaming, where the pure speed of physical RAM is important.
