How to increase RAM on Xiaomi: real ways and myths

Xiaomi smartphone owners often face a situation where apps start to “drop out” or the device noticeably slows down when multitasking. The reason usually lies in a lack of RAM (RAM). The manufacturer limits the amount of RAM even in flagship models, and with each update of Android and MIUI, the appetite of programs only grows. But are there ways to increase RAM on Xiaomi without buying a new phone?

In this article, we'll look at all the current methods, from the official features of virtual RAM to controversial hardware modifications. It's important to understand that not all methods are equally effective, and some can harm the device. We'll honestly tell you what really works, and what is a marketing scam or a dangerous experiment.

Before you make any changes, check the current RAM load in Settings → About Phone → Memory Status. If your free memory is less than 20%, optimization is definitely a good idea. But remember, increasing RAM is not a substitute for upgrading the processor or switching to a more modern model.

1. Virtual RAM: How to enable and configure

The safest and most official way is to use RAM Expansion (or MIUI RAM Extension) technology, which borrows part of the internal memory (ROM) for the needs of the RAM, creating what is called virtual RAM. The feature is available on most Xiaomi devices with MIUI 12.5 and later.

To activate it:

• 📱 Open the Settings. → Additionally. → Memory extension (on some models, the path may differ: Settings) → The phone. → Memory. → Expansion RAM)
• 🔧 Select the amount of virtual memory: usually offered 1 GB, 2 GB or 3 GB (maximum depends on the model and version). MIUI)
• 🔄 Restart the device to apply changes

Important: virtual RAM It's slower than the physical, because it uses slower flash memory, but for background processes and easy multitasking (like switching between messengers and the browser), that's enough, 3D-modelling) should not be calculated.

Optimizing your current RAM: What can be done without risk

Before you try to increase RAM, try to make the most of your memory. Here are the working methods:

• 🧹 Cleaning of background processes: in Settings → Annexes → App management disable auto-run for unnecessary programs, especially social networks and instant messengers that hang in memory.
• 🔄 Reboot once in a while 2-3 Android is getting clogged with cache over time, and even 6-8 GB of RAM may not work properly. Regular reboot clears up memory.
• 📱 Lightweight versions of apps: Replace Facebook with Facebook Lite and Chrome with Chrome Go. 2-3 less RAM.
• 🚫 Disabling animation: in Settings → Special facilities → Remove animations (or through Developer Settings) reduce animation to 0.5x — This will speed up the system.

Also check if the memory is being eaten by a virus or malware.

1. Install Malwarebytes or Dr.Web Light.
2. Scan the device for threats.
3. Remove suspicious apps from Settings → Apps.

💡

If free RAM is still not enough after optimizing, try rolling back the firmware to an older version of MIUI - sometimes new updates contain bugs that increase memory consumption.

3. Root access and modifications: risks and opportunities

For advanced users, there is a way to increase RAM by overclocking memory or changing the kernel parameters, but this requires root rights and carries serious risks:

• ⚠️ Loss of warranty – Xiaomi cancels warranty obligations if root access is detected.
• ⚠️ Unstable work – incorrect settings can lead to a “perpetual” reboot (bootloop).
• ⚠️ Security vulnerabilities – root opens access to system files for malware.

If you are prepared for the risks, here is a brief guide:

1. Unlock the bootloader through the Mi Unlock Tool (requires a Mi Account and wait 7-15 days).
2. Install a custom recap (TWRP) for your model.
3. Please use Magisk to obtain root rights.
4. Use Magisk modules like RAM Expander or edit files in /sys/devices/system/memory.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3 Pro) change in memory parameters may cause hardware damage to the controller RAM. Before experimenting, study the reviews on the forums 4PDA XDA-Developers for your specific model.

4. Hardware magnification of RAM: myth or reality?

There are suggestions online for a hardware upgrade of RAM on Xiaomi smartphones, supposedly to replace the memory chip with a more capacious one, which is technically impossible on 99% of models, and here's why:

The only semi-legal way to upgrade hardware is to buy a smartphone with a RAM connector (for example, Xiaomi Black Shark 4 Pro with the ability to add an SSD via the port), but such models are rare, and their cost is unreasonably high for the average user.

5. Alternative solutions: when to increase RAM can not

If none of these methods are suitable or the risks are too high, consider alternatives:

• 🔄 Cloudy RAM: Services like Microsoft SwiftKey or Google Assistant handle some of the tasks on their servers, unloading the device’s memory.
• 📱 External Devices: Connect Xiaomi Pad or laptop for resource-intensive tasks (for example, via Mi Share or Scrcpy for remote management).
• 💰 Trade-in: Many stores (including Mi Store) offer discounts on new models when renting out an old phone.

Also, pay attention to the performance modes in MIUI:

• 🔋 Settings → Battery → Performance mode – select “High Performance” to prioritize speed over energy savings.
• 🎮 For gamers: activate Game Turbo in settings (reduces background activity during games).

6. Frequent mistakes and how to avoid them

When you try to increase RAM, users often make critical mistakes.

1. Using RAM optimizers from the Play Market – applications like RAM Booster or Clean Master do not increase memory, but only close the background processes, which can disrupt the system.
2. Disabling system services – removing or “freezing” processes like com.miui.home through Titanium Backup will cause the interface to crash.
3. Ignoring compatibility – not all Magisk modules or cores are supported by your model. For example, the RAM Expander module may run on POCO F3, but will cause errors on the Redmi 9A.

⚠️ Note: On devices with MediaTek processors (e.g. Redmi Note 11 or POCO M4 Pro) Incorrect swap file settings may damage the data partition. Before experimenting, back up via Settings → Additionally. → Backup.
