MicroSD on Xiaomi with Android 11: how to connect, format and use a memory card

Xiaomi’s Android 11-based smartphones support memory expansion via microSD cards, but not all users know how to set them up properly. Unlike the newer OS versions, Android 11 on Xiaomi devices has restrictions on using memory cards as internal storage (Adoptable Storage) – a feature either missing or working with errors. However, even in such conditions, microSD can be a great solution for storing photos, videos and applications.

In this article, we will discuss all the nuances from choosing a compatible card to data porting and solving typical problems. Particular attention will be paid to the Redmi Note 10/10 Pro, POCO X3 Pro and other popular devices from 2020-2022, which originally came with Android 11. If your smartphone later upgraded to Android 12/13, some points may differ – we will mention this too.

Before you go to the setup, check if your model Xiaomi supports memory cards. For example, the flagship Mi 11 and Mi 11 Ultra are deprived of a microSD slot, while the budget Redmi 9A and POCO M3 allow you to expand memory to 512 GB. You can specify this in the device specifications or on the official website of Xiaomi.

1. Which microSD to choose for Xiaomi on Android 11

Not all memory cards work equally well with Xiaomi smartphones.

• 🔹 Speed class: minimum UHS-I (U1) Class 10 for recording video in Full HD. For 4K need U3 or V30.
• 🔹 Capacity: up to 512 GB (in practice, some Xiaomi models do not recognize cards over 256 GB – check compatibility).
• 🔹 Format: only microSDXC for cards over 32 GB (microSDHC cards up to 32 GB are also suitable, but less relevant).
• 🔹 Brand: Recommended by SanDisk Ultra, Samsung EVO Plus or Kingston Canvas Go! - less likely to cause reading errors.

⚠️ Attention: Cheap cards from nameless manufacturers can be unstable or even damage data. Check reviews on AliExpress or Amazon before buying - users often complain of fakes under well-known brands. 128GB 500-price ₽ It is highly likely to be a fake.

If you plan to map an application (even partially), choose models with high random write rate (R/W). For this, look for A1 or A2 (Application Performance Class) markings. A2 cards (such as Samsung EVO Select) are best, but cost more.

💡

Before buying, check the card for authenticity with the help of the utility H2testw (Windows or F3 (Linux/macOS). This will help to avoid fakes with low real capacity.

2 How to Insert MicroSD in a Xiaomi Smartphone

The process of installing the card depends on the design of the device. In most models, Xiaomi microSD slot is combined with a tray for the device. SIM-cards (hybrid slot) with the exception of some models POCO Redmi with a separate slot (for example, Redmi Note) 10S).
