How to increase RAM on Xiaomi phone: proven methods and life hacks

Why Xiaomi is running out of RAM and what to do about it

Have you noticed that your Xiaomi Redmi Note 12 or POCO X5 Pro is starting to slow down, apps are spontaneously shutting down, and games are lag even on medium settings? The reason for this is a lack of RAM. Smartphone manufacturers are saving on this component, installing 4-8 GB even in mid-budget models, while modern applications and games require more resources.

But don't rush to the store for a new phone! In most cases, you can increase RAM on Xiaomi by software methods - without a soldering iron and disassembling the case. In this article, we will analyze real-world ways to expand RAM, including virtual memory, system optimization and even hardware modifications (for advanced users), and also uncover myths that walk through the forums and only harm your device.

It's important to understand that you can't physically add RAM bars to your smartphone (unlike a PC), but there are workarounds, and let's start with the simplest and safest methods that even beginners can use.

Method 1: Virtual RAM – How to Turn Internal Memory into RAM

The most popular way to “boost” RAM on Xiaomi is to activate the RAM (RAM Expansion) function, which reserves part of the internal drive (usually 1-3 GB) and uses it as additional RAM, a method officially supported by MIUI, but has its own nuances.

How to turn on virtual RAM:

• 📱 Open the Settings. → The phone. → All characteristics.
• 🔧 Slip on the line RAM (or Memory in new versions) MIUI).
• 🔄 Find the Expansion option RAM (or virtual RAM) and move the slider.
• ⚙️ Select volume (recommended 2-3 GB for models with 4-6 GB of physical RAM).
• 🔄 Reboot the phone.

⚠️ Attention: Virtual RAM — It's not a magic wand. It only works when apps don't have enough memory to run in the background, but it doesn't speed up games and heavy tasks. It actually eats away at internal memory, reducing space for photos and apps. On models with 8.+ GB of RAM effect will be minimal.

Method 2: Optimize MIUI - how to free RAM without root

Often the problem is not the amount of memory, but its inefficient use. MIUI is known for its “appetite” for resources: background processes, unnecessary services and duplicate applications can take up to 30% of RAM. By optimizing the system, you will get more free memory without any “crutches”.

Checklist for RAM cleaning:

How to turn off autostart:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Facebook or TikTok).
3. Slip AutoRun and turn off the option.
4. Repeat for all "gluttonous" applications.

For deep optimization, use the developer mode:

• 🛠️ Activate it by tapping it 7 times on the version MIUI customized.
• 🔧 Turn on Do Not Stay Activated (kills background processes when exiting).
• 🎯 Limit background processes to 2-3 in developer settings.

💡

If the phone is slower after optimization, return the developer mode settings to their original state. Too aggressive process restriction can slow down the system.

Method 3: Using microSD as RAM – Does it work on Xiaomi?

In the forums, the advice to “use the memory card as a working memory card” is often used, theoretically, through the swap function in Linux (on which Android is based), but in practice, this method is ineffective and dangerous for Xiaomi.

Why you shouldn't try:

• ⚡ MicroSD speeds are 10 to 100 times lower than physical RAM (even if you have a microSD). UHS-II This will lead to lags.
• 🔥 Depreciation of the drive: constant overwriting of data will quickly “kill” the memory card.
• 🚫 There is no official support in MIUI — You will need to use unstable crutches (for example, ROEHSOFT RAM-Expander).
• 🔒 Root rights are required, which deprives of warranty and increases the risk of bricks.

If you want to experiment, here is a quick guide (at your own risk!):

⚠️ Note: On Xiaomi models with Snapdragon processors 4xx/6xx (Like Redmi. 9A or POCO M3) This method is almost guaranteed to lead to getting stuck. 13 Ultra, Black Shark 5) The effect will be minimal, but the risk of overheating remains.

Method 4: Update MIUI and firmware – hidden memory reserves

The performance of the smartphone depends on the firmware version. new MIUI updates optimize the system core and memory management, which can give +10-15% free RAM. For example, MIUI 14 added a feature called Deep Memory Cleanup, which automatically frees up resources for active applications.

How to update MIUI without losing data:

• 📲 Go to Settings. → The phone. → Updating the system.
• 🔄 Click Check Updates and install the latest version.
• 🔧 If the update does not come, download the firmware from the official Xiaomi website and install via the Update on file.

For advanced users, there is an option to switch to custom firmware (such as LineageOS or Pixel Experience), which lacks MIUI junk and better manages memory, but requires unlocking the bootloader and losing warranty.

💡

Updating MIUI to the latest version is the safest way to improve memory management. Custom firmware gives more boost, but requires technical skills.

Method 5: Hardware RAM Extension – Is It Real?

If you’re willing to take drastic measures, there are two hardware ways to boost Xiaomi’s RAM:

1. Replace the motherboard with a version with a large amount of memory (for example, with a 4 GB 6 Suitable for models where boards are interchangeable (e.g. Redmi Note) 10 Pro has versions with 6/8 GB of RAM. Cost: 3–5 thousand rubles + job.
2. RAM chip soldering is a highly complex procedure that requires professional equipment, only suitable for rare models (such as Black Shark), where the memory chips are located separately from the processor.

⚠️ Warning: Hardware interference deprives of warranty and may lead to:

• 🔥 Overheating (new chips may not match in heat output).
• 📉 Loss of performance (if the memory controller does not support the new volume).
• 💥 Complete failure of the phone (in case of soldering errors).

Before you go to the service, check if your model supports the replacement fee:

• 🔍 Find it on the forums (for example, 4PDA or XDA-Developers) theme on your model marked [RAM Upgrade].
• 📋 Clarify the items of supported boards (for example, for Redmi Note 9 Pro, boards with a marking are suitable). M2003J6A1G and M2003J6A1I).

Myths about increasing RAM on Xiaomi: what not to do

There are a lot of "advice" online that not only doesn't help, but also harms the phone.

Myth 1: “RAM booster speeds up the phone”

Applications like Clean Master or DU Speed Booster create the illusion of optimization, and they force the background to close, so they:

• 🔄 Applications open longer (the system has to reboot them from scratch).
• 📱 Increased battery consumption (frequent process restarts).
• 🚫 Some services (such as notifications) stop working.

Myth 2: “Switching off animation frees RAM”

Customization of window animation = 0.5x in developer mode does make the interface faster, but does not affect the amount of memory available. It is purely visual effect.

Myth 3: “Formation of the phone increases RAM”

Resetting to factory settings clears internal memory, but does not add physical RAM. Once reset, the phone can run faster just because it has fewer installed applications.

Myth 4: Root rights automatically increase memory

Root gives you access to deep settings, but it doesn't add RAM on its own. Moreover, illiterate root use can lead to:

• 🛑 Loss of warranty.
• 🔐 Blocking of banking applications (due to SafetyNet trigger).
• 💥 Phone Brick (if errors in the kernel settings).
