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

Xiaomi smartphones are known for their price-performance ratio, but even the most powerful models eventually start to “brake” due to a lack of RAM. If your Redmi, POCO or Mi has become slower, it may be time to think about expanding RAM. However, not everyone knows that physically adding RAM on most smartphones is impossible – unlike computers where you can just insert an additional RAM bar.

In this article, we’ll look at all the ways to increase RAM on Xiaomi devices, from virtual memory to hardware modifications (where possible), which models support expansion, how to properly configure virtual RAM, and what to do if the smartphone still lags. And we’ll also talk about the hidden MIUI feature, which allows you to use part of internal memory as additional RAM – this works even on budget models!

Can I physically add RAM to a Xiaomi smartphone?

The short answer is no, 99 percent of Xiaomi models. Unlike laptops or PCs, where RAM is represented by removable modules, Xiaomi smartphones (like most manufacturers) have RAM soldered into the motherboard.

• 🔧 Physical expansion is possible only in service centers with soldering - the procedure is complex, expensive and risky (can lead to failure of the device).
• 📱 Exceptions: Some flagship models (such as the Black Shark 4 Pro or Mi 10 Ultra) have connectors for extra memory, but this is extremely rare.
• ⚠️ The warranty will be waived for any interference with the hardware.

If you want to try hardware extensions, go to a dedicated service, but we recommend that you try software methods first, which are safer and often have noticeable performance gains.

⚠️ Warning: Solding off extra memory on a smartphone is not a standard procedure like replacing a battery. Even experienced craftsmen don't always take it, because the risk of damaging the motherboard is extremely high. Consider whether the game is worth a candle if you can buy a new smartphone with more RAM.

Virtual memory (RAM Expansion): how to turn on Xiaomi

The easiest and safest way to add RAM is to use RAM Expansion (or Memory Extension), which is available on most modern Xiaomi smartphones running MIUI 12.5+. This feature allows you to use part of the device’s internal memory as an additional RAM, for example, if you have 6 GB of RAM, you can “add” another 3 GB from storage.

How does it work? It creates a swap file on a fast flash memory and uses it to caching frequently used data, which is not a substitute for physical RAM, but it will help reduce the number of applications rebooted in the background.

Step-by-step instructions for activating RAM Expansion

1. Open Settings → About the phone and check the version of MIUI. The feature is available starting with MIUI 12.5.
2. Go to Settings → Additional → Expanded Memory (RAM).
3. Activate the memory extension slider and select the volume (usually offered 1, 2 or 3 GB).
4. Restart the device to apply the changes.

Importantly, the more virtual memory you allocate, the less space you have left for your files, and the best option is 1-2 GB if you have 6-8 GB of physical RAM.

Which Xiaomi models support RAM expansion?

RAM Expansion is not available on all devices, and here is a compatibility table for popular models. If your smartphone isn't on the list, check for the feature manually in the settings.

If your model doesn’t support RAM Expansion, don’t despair! there are alternative ways to optimize memory, which we’ll talk about later.

💡

Before activating virtual memory, clear the application cache in Settings → Storage → Clear the cache. This will help avoid lags when you first turn on the function.

Alternative ways to optimize RAM on Xiaomi

If physical or virtual memory expansion is not available, you can improve performance by other methods. Here are 5 ways to work:

• 🧹 Background cleaning: B MIUI There is a built-in function of Memory Cleanup (Settings) → Annexes → Cleaning. It closes down unused processes, freeing up RAM.
• ⚡ Performance mode: Enable Game mode (Settings) → Special facilities → Game mode) for prioritizing resources.
• 📱 Disable animation: Reduce interface animation reduces the load on RAM. Activated via Settings → The phone. → Version. MIUI (tap 7 times to turn on the developer mode, then find the Windows animation and install 0.5x).
• 🚫 Limiting background processes: In the developer settings (Settings) → Additionally. → For developers, set a background process limit for 2-3 processes.
• 🔄 Scheduled restart: Set up automatic reboot once a day (Settings) → Extended. → Reboot on schedule. This cleans the RAM of debris.

These methods won’t increase RAM, but they will help you use it more efficiently, for example, turning off animations can speed up the interface by 15-20%, and cleaning the background can free up to 500-800 MB of RAM.

⚠️ Warning: Don’t get carried away with limiting background processes too much. If you set a limit to process 1, some applications (e.g. messengers) may not receive notifications.

Can I install additional memory via microSD?

No, microSD memory card cannot be used as RAM, it is only designed to store files (photos, videos, music) and some applications (if the Adoptable Storage feature is supported in Android).

1. Some applications (like ROEHSOFT RAM-EXPANDER) allow you to create a swap file on a memory card and use it as virtual RAM, but this only works on rooted devices.
2. The efficiency of this method is extremely low, since the read/write speed of microSD is 10–50 times slower than that of internal memory.

If you really lack RAM, it’s best to consider buying a new smartphone with a lot of memory or using cloud services to unload the device.

What to do if the smartphone is still slowing down?

If you've tried all the optimizations, but the device is still slow, maybe the problem isn't with RAM. Here's a checklist for diagnosis:

• 🔋 Check the battery health in Settings → Battery. → Battery status. If the capacity drops below 80 percent, replace the battery, and the power drawdowns cause the lags.
• 🦠 Scan your device for viruses (for example, through Malwarebytes or built-in software). MIUI Security).
• 📉 Check the processor load in Settings → The phone. → System status. CPU loaded%+ In simple, perhaps there is a background application that “eats” resources.
• 🔄 Reset the settings to factory (Settings) → Additionally. → Reset settings. Pre-reverse backup!

If nothing helps, your smartphone is probably outdated, and you should consider buying a new model with 8-12 GB of RAM (for example, Xiaomi 14 or POCO F6 Pro).

💡

Brakes can be more than just RAM, but often the problem is a worn-out battery, a processor overheating, or viruses, and always check these factors before you buy a new device.
