How to add RAM to Xiaomi: memory expansion and optimization

Xiaomi smartphone owners often face a situation where a lack of RAM begins to slow down the device, apps are offloaded from the background, games are suspended, and the system is slower than in the first days after purchase. This is especially true for mid- and low-end models, where the physical volume of RAM is limited by the manufacturer to reduce cost.

In this article, we will discuss all the legal and safe methods that will help you optimize the memory on your device. We will look at the built-in MIUI and HyperOS features that allow you to use part of internal memory as an additional, and also touch on methods of software optimization without obtaining superuser rights. It is important to understand that physically replacing the memory chip in modern monolithic structures is almost impossible without complex hardware, so the main emphasis will be on software solutions.

Before you start taking action, it’s worth assessing the current state of your gadget. Xiaomi provides powerful monitoring tools that users often ignore. Understanding which processes consume the most resources is key to successful optimization. Next, we’ll detail the steps to set up the system for maximum performance.

RAM Plus memory extension in MIUI and HyperOS

Xiaomi’s current shells, such as MIUI 12.5, MIUI 13, 14, and the new HyperOS, feature a built-in virtual memory extension feature, known as Memory Extension or RAM Plus, which allows you to reserve a portion of permanent storage (ROM) and use it as additional RAM, the most secure and regular way to do so without requiring third-party software.

To activate this option, you need to go to the system settings. The path may vary slightly depending on the firmware version, but the overall algorithm remains the same. You usually need to go to Settings → About Phone or Settings → Advanced Settings. There you will find a paragraph related to memory management. If the function is available for your model, you can choose one of the proposed expansion options, for example, +2 GB, +3 GB or +4 GB.

⚠️ Attention: Using the memory expansion function increases the load on the device’s flash memory. On older smartphones with worn-out storage, this can lead to accelerated failure of internal memory or a decrease in the overall system speed.

Once you have volume, the system will require a reboot. It's important to understand that virtual memory is slower than physical memory, so performance gains on heavy tasks may be small, but multitasking will definitely improve. Applications will be less likely to be unloaded from the backgrounds of the mode, which will create a smoother interface experience.

Software optimization and disabling of system services

If built-in memory expansion isn’t enough or it’s not available on your model, smart software optimization comes to the rescue. Android is a system that runs a lot of background processes by default. Cleaning up autoboots and disabling unnecessary services can free up hundreds of megabytes of valuable RAM. Start by analyzing installed applications.

Remove or freeze apps that you don't use, especially pre-installed software, which often hangs in the background, and for a deeper setup, you can use the developer mode, and you can activate it by clicking on the build number in the About Phone section several times, and then you'll see a new Developers item on the menu.

Inside the developer menu, we're interested in animation settings and background limits. Changing the animation scale won't add physical bytes of memory, but it will visually speed up the interface. A more important parameter is limiting background processes. However, you should be careful here: too tight a constraint can disrupt messengers and system services.

• 📱 Disable unnecessary services in the Settings menu → Annexes → Application management.
• 🚀 Use the built-in security utility to clean the cache and speed up the system.
• 🛑 Disable auto-runs for heavy applications that aren’t needed all the time.
• 🔄 Regularly reboot the device to reset the accumulated cache of processes.

💡

Periodic reboot of the smartphone (at least once a week) helps to clear the memory of “junk” processes and fragmented data, which has a positive effect on performance.

Use of third-party applications for memory management

There are many apps in the Google Play Market that promise to increase RAM, most of which are just cache cleaners, but some are able to create swap files on root-enabled devices. For users without superuser rights, optimizers like Files by Google or Xiaomi’s dedicated snails are effective.

Apps like SWAP No Root try to emulate the paging file without root rights using special Android APIs. The effectiveness of these methods varies from model to model. On some devices, this gives a noticeable increase, on others, it only consumes battery power. Before installing, be sure to read reviews for your smartphone model.

And there's the heavy launchers, too. If you use a customized shell with lots of widgets and live animations, it consumes a lot of RAM. Going to a standard launcher or lighter alternatives like Nova Launcher can be a big drain on the system.

⚠️ Warning: Avoid installing questionable “accelerators” from unverified sources. They often contain ads, miners or malicious code that, on the contrary, will load the processor and memory, reducing autonomy.

Comparison of methods for increasing productivity

So that you can choose the most appropriate way to use your scenario, we've developed a comparison table that will help you assess the risks and potential benefits of each method, and it's important to consider not only the desired outcome, but also the technical condition of your device.

As you can see from the table, regular funds and manual cleaning are the safest options. Root rights open up new possibilities, but it is not guaranteed and requires a deep knowledge of Android. For most users, the best choice will be a combination of built-in memory expansion and regular manual cleaning.

Advanced customization through ADB and Developer Mode

For power users who are not afraid of the command line, there is a method of fine-tuning through ADB (Android Debug Bridge), which allows you to disable system components that cannot be removed by standard means, for example, you can disable analytics services or MIUI advertising modules that consume resources.

You'll need a computer to work, USB-cable and installed drivers ADB. After connecting the smartphone and enabling debugging USB, You can send commands to disable packets. For example, a command to remove a particular system application looks like pm uninstall. -k --user 0 This frees up space and reduces the load on the processor and memory.

adb shell pm list packages | grep miui


adb shell pm uninstall -k --user 0 com.miui.analytics

Be extremely careful when using ADB. Disabling critical system components can lead to a cyclical reboot or unstable phone. Always check the purpose of the package before removing it. It is better to double-check the information in specialized forums than to get a broken device.

Physical Limitation and Device Selection

The physical limitations of mobile technology need to be clearly understood. Smartphone RAM is soldered on the motherboard. Unlike a PC where you can add a DDR bar, it is technically difficult and economically inefficient to replace a memory chip on a Xiaomi phone, and the cost of such a service in a service center often exceeds half the cost of the used device itself.

If you are not enough with 4 or 6 GB of memory, even after all the optimizations, this is a signal that the device is outdated for your tasks. Modern applications and games require more resources, in which case it is more rational to consider buying a new model with a large amount of RAM than trying to revive an old gadget with exotic methods.

When choosing a new smartphone, pay attention not only to the number in the characteristics, but also to the type of memory. LPDDR5 is much faster than its predecessors. Also important is the type of UFS 3.1 or higher, since the speed of reading / writing depends on the efficiency of virtual memory and the system as a whole.

⚠️ Attention: Attempts to sell memory chips at home in 99% of cases lead to a complete failure of the smartphone without the possibility of recovery.

💡

Software methods can improve multitasking, but are not able to turn a budget smartphone into a flagship in terms of the speed of heavy applications.
