How to Insert Additional Memory in Xiaomi Phone: Card Selection, Installation, and Setup

Xiaomi smartphones are some of the most popular devices on the market, but even flagship models face a shortage of internal memory over time. High-resolution photos, heavy games, app cache and system updates quickly fill the available space. The solution is to install an additional microSD card that will expand your phone’s capabilities by 256 GB, 512 GB or even 1 TB.

However, not all Xiaomi models support memory cards, and those that do often require the right setup to work in Adoptable Storage mode. In this article, we will learn how to choose a compatible card, physically install it in the slot, configure it as internal or external memory, and transfer data without loss.

What Xiaomi phones support microSD cards

Not all Xiaomi devices are equipped with a microSD slot. For example, the flagship Xiaomi 13/14 and Black Shark series are often deprived of this option for the sake of a thin body or cooling system. At the same time, budget and mid-budget models - Redmi Note 12/13, POCO X5/M5, Redmi 10A/12C - usually support memory expansion.

You can check the presence of the slot:

• 🔍 In the characteristics of the model on the official website of Xiaomi (section "Memory").
• 📦 On the device box – usually indicated support for microSD up to 1 TB.
• 🔧 Visually: the slot can be hybrid (instead of the second one) SIM) or a separate (separate) scattering).

If your model does not support microSD, the alternatives are:

• 🖥️ Use cloud storage (Mi Cloud, Google Drive).
• 📁 Connect the outside SSD/flash-drive OTG-adapter.
• 🔄 Regularly clean cache and unnecessary files through Settings → Warehouse.

How to choose a memory card for Xiaomi: speed, volume and brands

The wrong choice of microSD card can lead to slowing down of the phone, recording errors or even data loss.

Critical error: UHS-II cards (like SanDisk Extreme Pro UHS-II) are physically incompatible with UHS-I slots on Xiaomi phones - they just won't be recognized. Also avoid High Endurance cards - they're optimized for DVRs and wear out faster with frequent overwriting.

⚠️ Note: If you plan to use the card as internal memory (Adoptable Storage mode), choose models with high random write speeds (A2). Maps without this marking will be slowed down when installing applications.

adb shell pm set-install-location 2

This command will force the system to install applications on default SD-Attention: not all applications will work correctly!

💡

Class A2 memory cards (such as the Samsung EVO Plus A2) are optimized for random writing, which is critical for installing applications. They cost more, but pay off with stable work.
