How to save everything to Xiaomi memory card: Full instructions

Xiaomi, Redmi and Poco smartphone owners often face a lack of built-in storage, especially in budget models with 32 or 64 GB of storage. When the gallery is crowded and the notification system persistently reports a shortage of space, the only sensible way out is to use a MicroSD card.

However, simply inserting the drive into the slot is not enough. In order for Android to automatically direct new files to an external medium, rather than clog the internal memory, you need to perform a number of settings in the shell. MIUI In addition, there are nuances of working with applications that do not always support direct porting to the Internet. SD-card without root rights or special manipulations.

In this guide, we will look at all the steps from choosing the right card speed class to fine-tuning the storage system. You will learn how to make a memory card the main place to shoot photos and videos, where downloaded files are transferred by the browser and how to avoid common formatting errors. Modern versions of MIUI have hidden limitations on the portability of some system applications, so it is important to understand the difference between “portable storage” and “internal memory”.

Choosing the right memory card for a smartphone

Before you start setting up, it’s critical to make sure your memory card meets the requirements of a modern smartphone.Using cheap and slow drives can cause the device to start running slower, photos will be stored with a delay, and video can be interrupted when writing in 4K. Write and read speeds play a crucial role here.

Note the marking. For comfortable work in conjunction with Xiaomi, it is recommended to use UHS-I or UHS-II cards. The minimum speed class should be Class 10, but it is better to focus on the marking V30 or higher. This guarantees a stable recording speed of at least 30 MB / s, which is necessary for modern cameras.

💡

If you plan to record video in 4K, choose cards marked A2 – they provide higher speed of random read and write, which is critical for the work of applications from the memory card.

Older phones may not work properly with cards larger than 128GB or 256GB. Check the specification of your model on the manufacturer's official website. Often the maximum supported volume is listed in the specifications, but in practice, devices often "see" and larger cards, such as 512GB or 1TB.

Primary installation and formatting of the drive

After buying the card, you need to install it correctly. In most models of Redmi and Xiaomi, the tray is combined: one side for the card. SIM-The card, the other for MicroSD, it's important not to confuse orientation and not to damage the contacts when inserted. The phone must be turned off before removing the tray to avoid damaging the file system.

Once the device is turned on, the system will automatically detect a new drive. A message will appear in the notification curtain. Click on it or go to the Settings menu → About Phone → Storage. The system will suggest formatting the card. This process is mandatory, since the card must be formatted in the exFAT or FAT32 file system to work correctly with Android.

In the process of formatting, all data on the card will be deleted. If it had important files, copy them to your computer in advance. Once the procedure is complete, the system will ask how you plan to use this drive: as a portable storage or as internal memory. The Portable Storage mode is the most versatile and secure option for most users, allowing you to store photos, videos and music.

⚠️ Note: When formatting a card as an "Adoptable Storage," it's encrypted and linked to a particular device, and you can't just move that card to another phone or computer without losing data and formatting it again.

Setup of automatic photo and video saving

One of the main tasks for the user is to transfer the storage space of photos and videos. The default camera often continues to write files into internal memory, ignoring the free space on the computer. SD-To change this behavior, you need to go to the settings of the camera application itself.

Open the Camera app, click on the three bars in the top right corner, and select Settings. Scroll down to the Save section. There should be a Save on switch. SD-Activate it. From now on, all new images and videos will be automatically recorded to an external drive, freeing up valuable space in the system.

However, it is worth considering that some shooting modes, such as 8K Video or high-bitrate Pro mode, may require recording speeds that a cheap card cannot provide. In such cases, the camera may force the file to be stored in internal memory or issue an error.

For users who are actively using third-party photo processing apps, such as Lightroom or Snapseed, it is also useful to check their individual settings. Many editors can specify the default path for exporting finished images. SD-map as a target directory so as not to take up space with temporary rendering files.

Application transfer and working with internal memory

The issue of porting installed applications to a memory card in modern versions of Android and the MIUI shell has been controversial, with Google officially limiting this option a few years ago for reasons of stability and security, and many app developers now ban installing their products on external drives.

However, some applications still support portability. To check this, go to Settings. → Annexes → All applications. Select the desired application from the list. If the button "Move to" SD-The card is active (not grey), you can move the heavy app by freeing up space in the system partition. If the button is not available, portability is impossible without root permissions.

There is a function "Memory Extension" when the system uses a part of the system. SD-As a virtual addition to RAM or internal storage, this is often done through formatting the card as internal memory at Xiaomi, which allows more applications to be installed on the card, but reduces the overall speed of the interface, as the read speed is often implemented. SD-card significantly below the speed of the embedded memory chip eMMC or UFS.

⚠️ Note: Do not transfer messengers (WhatsApp, Telegram) and banking applications to the memory card. This can lead to loss of correspondence history when retrieving the card or problems with the security and operation of notifications.

File management and storage cleanup

To effectively manage files in smartphones Xiaomi uses a standard Explorer, which is called “Conductor”, or more advanced “Files” from Google, which can manually move already accumulated files from internal memory to the card, this is especially true for download folders from browsers and instant messengers.

Find the Download or Download folder in the internal storage. Select the files you want to move, select the Move option (not Copy to avoid duplicate data) and specify the corresponding folder on the SD-Regular manual cleaning helps keep the system in good shape.

💡

Use the Cleanup function in the Xiaomi Security app – it can find large files and duplicates, offering to transfer them to an external medium.

Also worth paying attention to is the social media cache folders. Telegram, for example, can take up tens of gigabytes. In the Telegram settings (Settings → Data and Memory → Memory Use), you can change the way you store downloaded files to a memory card, which will prevent the internal memory from being inflated by the videos and photos you see.

If you use your smartphone for navigation, offline maps (such as Yandex Maps or Google Maps) also take up a lot of space.In the settings of these apps, find the "Storage of Maps" or "Saved Maps" section and indicate the path to the map. SD-This would free up a lot of volume, because maps of regions can weigh several gigabytes each.

Solving problems and reading errors

Sometimes users are faced with a situation where the phone stops seeing the card, or files are saved with errors. Often the reason lies in the file system. If the card was formatted on a computer in the NTFS system, the phone can see it, but does not have the rights to write. You need to reformat the card to exFAT directly through the smartphone.

Another common problem is falsely reporting card damage, which can occur when you extract a card without first unmounting. Always use the "Extract" command in the notification curtain or in the storage settings before physically removing the tray. A sudden power outage while writing data is guaranteed to cause logical errors in the file system.

If you have persistent reading errors, try cleaning the contacts of the card. Gently wipe the golden contacts with a stripe or soft cloth soaked in alcohol. Contact oxidation is a common cause of unstable operation, especially if the phone is used in high humidity conditions.

⚠️ Warning: If the memory card suddenly starts to read very slowly or files begin to disappear, this is a sign of physical wear or failure of the controller.
