Memory card setup in Xiaomi Redmi 5: from installation to optimization

Xiaomi Redmi 5 is a popular smartphone with support for microSD cards up to 256 GB, but many users face problems when you first set up. The map is not defined, applications are not transferred, and files are stored in internal memory. In this article, we will analyze all the nuances from the correct installation to fine optimization of storage.

Feature Redmi 5 – hybrid slot for two SIM-card SIM + microSD. That means that when you use a memory card, you have to donate a second memory card. SIM-It's also important to consider the firmware version: MIUI 9-14 map configuration algorithm is different. We will look at universal methods that are relevant for all versions.

Preparation of a memory card: selection and verification

Not every microSD card is suitable for Redmi 5. The manufacturer recommends using cards of class UHS-I (Class 10) or higher at a write speed of at least 10 MB / s. Cheap cards without certification can cause errors when writing files or transferring applications.

Before installation, perform a check:

• 🔍 Check authenticity: use utilities like H2testw (Windows or F3 (Linux/macOS) Detecting counterfeit cards with low capacity.
• 📏 File system format: Redmi 5 supports FAT32 (up to 32 GB) and exFAT (over 32 GB). NTFS not recommended.
• 🛡️ No damage: If the card has been used in other devices, format it via PC (not fast formatting!).

⚠️ Note: 128GB and higher cards may not be defined in older versions MIUI (Update the firmware before installation.

2. Installation of the card in the slot: step-by-step instructions

The memory card slot in Redmi 5 is located on the left side of the device.

1. Turn off the phone (required!) Removing the card on the device on could damage the contacts.
2. Use a paper clip or a special key to retrieve the tray, insert it into the hole next to the slot and press until you click.
3. Place the microSD card in the top slot of the tray (bottom for nano-SIM). The card's contacts should be facing down.

3. Map formatting: internal vs external storage

When you first connect, Redmi 5 will offer you to format your card as an internal or external storage, and the functionality depends on this choice:

For formatting as an internal storage:

1. Go to Settings. → Memory.
2. Click on the name of the card (for example, SD-map: 64GB).
3. Select Configure as internal storage → Clean and format.
4. Confirm the action. It'll take 1-3 minutes.

Important: Once formatted as internal storage, the card will not be read on a PC or other phone without completely erasing the data.

💡

If the card is not formatted as an internal card, check its speed class.

4. Transfer data and applications to a memory card

Even after formatting as an internal storage, not all applications can be transferred to the map. System programs and some games (for example, PUBG Mobile or Genshin Impact) remain in internal memory.

1. Open the Settings → Applications.
2. Select the app you want (such as WhatsApp).
3. Click Warehouse → Change → Select a memory card.
4. Confirm the transfer. Some data (cache) may remain in the internal memory.

To transfer files (photos, videos, music):

• 📁 Use the Conductor. MIUI: highlight files → Cut out → Go to the map → Insert.
• 🖥️ Connect your phone to your PC through USB (File Transfer mode) and copy data manually.
• ☁️ Upload files to the cloud (Google Drive, Mi Cloud) and download them directly to the map.

⚠️ Note: Transferring apps to a map can reduce their performance. Tests show that games on microSD Class 10 run 15-30% slower than in internal memory.

5. Optimization of the memory card

To ensure that the memory card is stable:

• 🔄 Clean the cache regularly: go to Settings → Memory. → Clear the cache. That'll free up 1 to 3 GB of space.
• 📊 Turn off auto-saving garbage: in the Gallery, turn off the option Auto-save screenshots and Download MMS.
• 🛡️ Use antivirus: scan the card once a month (for example, through Google Play Protect or Dr.Web).
• 🔋 Watch out for wear: memory cards have a limited record life (especially cheap models). If you notice slow work (hangs when copying), replace the card.

To speed up the work of the card as an internal storage:

1. Go to Settings → Additional → For developers (if the item is missing, tap 7 times on the MIUI version in About Phone).
2. Activate the option Forced Stop Applications for Background Processes.
3. Enable Do Not Save Actions to Save Resources.

💡

Formatting a card as an internal storage device speeds up applications by 10-20%, but reduces card life due to frequent overwriting.

6. Solving common problems

If the memory card is not identified or is not working correctly:

If the phone is writing "SD-map damaged":

1. Remove the card and connect it to the PC.
2. Run the command line on behalf of the administrator and execute: chkdsk X: /f (where X is the card disk letter).
3. If the errors are not corrected, format the card in exFAT.

⚠️ Warning: If the card is no longer identified after the phone falls, the problem may be in the damaged slot, in which case repairs are required at the service center (replacing the connector will cost 800-1500 times). ₽).

7.Alternative ways to expand memory

If the memory card doesn’t fit or the slot is damaged, consider alternatives:

• ☁️ Cloud storage: Google Photos (unlimited space for compressed photos), Mi Cloud (5 GB free), Yandex Disk (10 GB).
• 💻 USB-OTG: Connect the flash drive through the adapter USB-C/OTG. Redmi 5 sticks up 128 GB.
• 🔄 Optimizing internal memory: Remove the app cache in Settings → Memory. Move media files to the cloud. Use the lighter versions of apps (Facebook Lite, Messenger Lite).

For the use of USB-OTG:

1. Buy a Micro-USB adapter → USB-A (cost ~200 ₽).
2. Connect the flash drive (formatted in FAT32/exFAT).
3. In the notification that appears, select Use as USB-accumulator.
