How to increase RAM on Xiaomi smartphones: all the ways and nuances

Xiaomi smartphone owners are faced with the question of whether it is possible to add RAM to their device, especially for budget models, where 2-4 GB of RAM quickly become a bottleneck when multitasking or running modern games. Unlike computers, where RAM can be physically replaced, smartphones are more difficult β€” but not hopeless.

In this article, we will look at all the possible ways to increase RAM on Xiaomi, from official features to alternative solutions. You will learn which models support memory expansion due to embedded technologies, and where you will need to interfere with the system. Importantly, not all methods are safe, and some can lead to loss of warranty or unstable device performance.

What is RAM and why it is not enough on Xiaomi

RAM is a temporary storage device that uses the processor to quickly work with applications. The more RAM, the more programs can be stored in memory at the same time without hanging. On Xiaomi smartphones, the typical symptoms of a lack of RAM are:

  • πŸ”„ Applications are constantly restarted when switching between them.
  • 🐒 Slow down animations and freezes when opening menus or launching games.
  • 🚫 Memory Lack Memory Message When Trying to Open a New App.
  • πŸ”‹ Fast battery discharge due to constant reboot of background processes.

Smartphone makers, including Xiaomi, often save on RAM in budget models. For example, the Redmi 9A or Poco C31 were produced with 2-3 GB of RAM, which by the standards of 2026 is clearly not enough for comfortable work. Even mid-budget devices like the Redmi Note 11 with 4 GB can β€œbrake” when used actively.

Unfortunately, you can't physically replace or add the RAM bar to your smartphone -- the memory is sealed on the motherboard -- but there are a few software and hardware workarounds that we'll talk about later.

Official ways to increase RAM on Xiaomi

Some Xiaomi models support RAM Expansion (or Memory Extension), which allows you to use part of your internal memory (ROM) as an additional RAM, which works at the firmware level and does not require root rights.

  1. Open Settings β†’ About the phone β†’ All the characteristics.
  2. Find the β€œRam memory” line and tap it several times (on some models you need to go to Settings β†’ Additional β†’ Memory).
  3. Select Memory Extension or RAM Boost.
  4. Set the desired amount of additional memory (usually 1 to 3 GB).
  5. Reset the device.

Importantly, this feature is not available on all devices, and here is a list of Xiaomi models that support RAM Expansion:

SeriesModels.Max. RAM extension
Xiaomi 1212, 12 Pro, 12X3GB
Redmi Note 11Note 11, Note 11 Pro, Note 11S2GB
POCO F4F4, F4 GT3GB
Redmi K50K50, K50 Pro, K50 Gaming3GB

Note that virtual memory is slower than physical RAM, but it can improve multitasking a little, and some of the internal storage will be used for this function.

Expanding RAM through root and modified firmware

If your model does not support RAM Expansion, but you have a background in root rights, you can try alternative methods. One of them is using a module. RAM Expander (Swap) in Magisk. This way creates a swap file on internal memory or SD-The card that the system uses as an additional RAM.

⚠️ Note: Getting root rights voids the warranty and can cause the device to run unstable, and misconfigured swap file settings can speed up the wear and tear of internal memory (especially if cheap flash memory like eMMC is used).

Instructions for experienced users:

Get root rights through Magisk

Install the RAM Expander (Swap) module from the Magisk repository

Make a backup copy of the data

Charge your phone at least 50%

-->

  1. Install the RAM Expander (Swap) module via Magisk Manager.
  2. Reset the device.
  3. Open the Terminal app and type in the command to create a swap file (e.g., 2GB): su dd if=/dev/zero of=/data/swapfile count bs=1024=2097152 mkswap /data/swapfile swapon /data/swapfile
  4. To activate swap automatically when you download, add /data/swapfile none swap defaults 0 0 to /etc/fstab.

The effectiveness of this method depends on the speed of internal memory. On devices with UFS 2.1/3.0 (for example, Xiaomi 11T or POCO F3) swap will work better than on budget devices with eMMC (for example, Redmi 9C).

What is swap and how does it work?
Swap is an area on a hard drive (or flash memory) that is used as an add-on to RAM. When physical memory is scarce, the system transfers some of the data to swap. However, the read/write speed of flash memory is hundreds of times lower than that of RAM, so swap is always a trade-off between performance and stability. On Android, this method is less efficient than on PCs, because of the way memory is managed in mobile OSes.

Use of the SD-Cards as additional memory

Another way to unload RAM is to transfer some of the applications and data to a microSD card, which doesn't increase RAM directly, but reduces the load on it, freeing up resources for background processes. Starting with Android 6.0, Xiaomi has Adoptable Storage, which allows you to format RAM. SD-map as an internal storage.

How to do this:

  1. Insert a microSD card (UHS-I U3 or higher is recommended).
  2. Go to Settings. β†’ Warehouse β†’ [Name of name SD-map] β†’ Three dots (menu) β†’ Storage settings.
  3. Choose the internal memory (or Format as Internal).
  4. Confirm the formatting (all data on the map will be deleted!).
  5. After restarting, transfer the applications to SD-map in Settings β†’ Annexes β†’ [Select an application] β†’ Warehouse β†’ Change.

⚠️ Note: Not all applications support portability SD-It also makes the memory card faster than the internal storage, especially if you use a cheap microSD for games and heavy applications (such as Genshin Impact or a computer or a computer). PUBG Mobile: This method can impair productivity.

The best memory cards for Xiaomi in 2026:

  • πŸ† Samsung EVO Plus U3 β€” Optimal Price/Quality Relationship.
  • πŸ’° SanDisk Extreme Pro A2 β€” High speed for games and applications.
  • πŸ”₯ Lexar Play 1000x β€” Good choice for video recordings in 4K.

Optimizing the system to save RAM

Before you try to increase RAM, try optimizing your current memory. Many performance problems on Xiaomi are not due to a lack of RAM, but to improper settings or background processes. Here are some proven ways:

  • 🧹 Turn off the autoload of unnecessary apps: Go to Settings β†’ Annexes β†’ Autostart management and disable autoboot for underutilized programs.
  • ⚑ Activate Performance Mode: In Settings β†’ Special facilities β†’ Performance mode (or Settings) β†’ Battery β†’ Performance mode) turn on the option for games.
  • πŸ”„ Limit background activity: In Settings β†’ Battery β†’ Background Limitation Select Apps That Shouldn't Work in the Background.
  • πŸ—‘οΈ Clean the cache regularly: Use the built-in Security utility (Settings) β†’ The phone. β†’ Memory. β†’ Clear) or the CCleaner application.

It's also worth checking if a particular application is consuming too much memory.

  1. Open Settings β†’ About Phone β†’ Memory β†’ Memory Use.
  2. See which apps take up the most RAM.
  3. If an app consumes a disproportionate amount (like Facebook or Instagram), try using their Lite versions or alternatives like Hermit.

πŸ’‘

If your Xiaomi smartphone supports MIUI 14 and newer, turn on Smart Optimization in Settings β†’ About Phone β†’ Memory. It automatically closes the background processes when RAM runs out without affecting the main applications.

Hardware modifications: is it possible to physically add RAM

Unlike computers where RAM can be replaced or added, Xiaomi smartphones (as in most modern devices) have RAM sealed on the motherboard, which cannot be physically replaced without specialized equipment and soldering skills. BGA-Even in service centers, these operations are:

  • πŸ’Έ It is very expensive (it is often cheaper to buy a new phone).
  • ⚠️ Potential damage to other components (processor, modem).
  • 🚫 Cancellation of warranty and may lead to unstable work.

The only theoretical way is to sell the RAM chip from the donor board, but this is:

  1. Requires an identical donor (even small differences in the fee revision will make the operation impossible).
  2. It is possible only in specialized laboratories (for example, in JC Repair or iFixit-services).
  3. Does not guarantee performance – even with successful soldering, compatibility problems may arise.

If you really lack RAM, it’s more rational to consider buying a new smartphone with more memory, for example, instead of the Redmi Note 10 with 4 GB of RAM, you can take the POCO X5 Pro with 8 GB β€” the difference in performance will be huge.

πŸ’‘

Physically increasing RAM on Xiaomi smartphones is technically possible, but economically impractical. The risks of damaging the device or getting unstable work far outweigh the potential benefits.

Frequent Mistakes and How to Avoid Them

When trying to increase RAM on Xiaomi, users often make critical errors that lead to a device β€œbreakdown” or data loss.

  • πŸ”§ Using unofficial firmware without backup: Install custom ROM (For example, LineageOS or Pixel Experience without a backup can cause loss of the service. IMEI or a broken modem.
  • πŸ”‹ Slow card swap: If you use a Class 4 or Class 10 microSD UHS), Swap will slow down the system more than it helps.
  • πŸ”„ Swap File Settings: Too much swap (such as 4GB on a 32GB phone) can cause flash memory to wear out quickly.
  • πŸ› οΈ Self-soldier without experience: Attempts to solder RAM chips at home almost always end in damage to the board.

To minimize the risks:

⚠️ Before any manipulation of the system or iron, make a full backup through the TWRP Also check if your model supports unlocking the bootloader (some new Xiaomis do not allow this).

If you’re unsure of your skills, you’d better go to a service center or consider buying a new device, like the POCO X6 Pro or Redmi K70 smartphones in 2026 offering 12-16GB of RAM at an affordable price.

Can I increase the RAM on Xiaomi Redmi 9A?
On the Redmi. 9A No official support RAM Expansion, but you can try it: Use it SD-card as internal memory (see section above) Get root and create swap file (risky), optimize system (disable autoboot, clear cache.
How much RAM does it take to play games in 2026?
Minimum requirements for popular games: PUBG Mobile / Call of Duty Mobile: 4 GB (6 GB for high settings). Genshin Impact: 6 GB (8 GB recommended). Honor of Kings / Mobile Legends: 3 GB. Diablo Immortal: 4 GB. For a comfortable game in 2026, 8 GB of RAM and above is optimal.
Is RAM Expansion really a bad thing for your internal memory?
Yes, frequent write/reading to a swap file increases wear on flash memory, especially if you use a cheap eMMC. However, on modern smartphones with UFS 2.1/3.0, this effect is minimal. To extend memory life: Do not install swaps greater than 2-3 GB. Use high-quality memory cards for Adoptable Storage. Clean the cache regularly.
Can I increase the RAM on Xiaomi without root?
Yes, but only if your model supports RAM Expansion (see table above). Other methods (swap, modified firmware) require root rights or unlocked bootloader.
Which is better: buy a new phone or try to increase RAM?
If your smartphone is older than 2-3 years (for example, Redmi Note 8 or POCO X3), it is more rational to consider buying a new device. Modern models (for example, Redmi Note 13 Pro+ or POCO F6) offer 8-12 GB of RAM at an affordable price, and their performance will be higher than that of an old phone even with extended memory. You should try to increase RAM only if: Your phone is relatively new (released after 2022). You are willing to risk warranty and stability. You lack memory only for easy tasks (social networks, instant messengers).
