How to Free Memory for Xiaomi Redmi 6: Transferring Applications to the Flight SD-map

Xiaomi Redmi 6 owners often face a lack of internal memory, especially if the smartphone has been in use for several years. Even after cleaning the cache and removing unnecessary files, system updates and new applications take precious megabytes. SD-map, but in MIUI This process has nuances that few people know about.

Unlike the newer Redmi models, where the application portability function can be blocked by the manufacturer, Redmi 6 (released in 2018 on the basis of Android 8.1 Oreo with the MIUI shell 9/10) still supports this feature. However, the standard way through settings does not work with all applications, and some programs (for example, messengers or games with protection) fundamentally refuse to move. In this article, we will analyze all working methods from official to bypass, including setting up a memory card as an internal drive and using ADB.

Before you start, consider: transfer applications to SD-The card may affect performance (especially if the card is Class 4 or Class 6), and some features (such as widgets or auto-run) may not work properly, but if the alternative is constant notifications of memory shortages, the risk is justified.

1. Preparation SD-maps: selection and formatting

Not every memory card is suitable for porting applications. Xiaomi Redmi 6 supports microSD up to 256 GB, but two parameters are important for stable operation: speed class and file system. The best option is a Class 10 card or a UHS-I (U1/U3) card with an exFAT or FAT32 file system.

If you just bought a card, you need to format it directly in your smartphone:

  1. Put it in. SD-card in the slot (in Redmi 6 it is combined, so you will have to take out the tray for the game). SIM-map).
  2. Go to Settings. → Warehouse.
  3. Tap by name. SD-maps, for example, SD-map: 64GB).
  4. Choose Format → Internal Memory (if you want to use the card as an extension of the internal drive) or Portable Storage (if you plan to port only individual applications).

⚠️ Warning: Formatting as internal memory will bind the card to this device, and once removed, it will not be read on another smartphone or PC without completely erasing the data, and it may slow down some applications.

If you've already used the card, copy important files to your computer before formatting it, and after the procedure, all data will be erased.

📊 What? SD-You are using the card in Redmi 6?
Class 10 (up to 32 GB)
UHS-I U1 (32-128GB)
UHS-I U3 (128-256 GB)
I don't know what I have.
I don't use it.

2. Standard application portability through MIUI settings

The easiest way is to use the built-in MIUI feature.It is suitable for most user applications (such as social networks, simple games or utilities), but does not work with system services and some protected programs (such as bank clients).

Instructions:

  1. Open the Settings → Applications.
  2. Select the app you want to migrate (like Facebook or VK).
  3. Slip on Warehouse.
  4. Click Change (or Move to) SD-card if the button is active).
  5. Confirm the action and wait for the process to be completed.

If the button is moved to SD-The card is inactive (grey), so it is:

  • 🔹 The app does not support transfer (often found in cache games or messengers like WhatsApp).
  • 🔹 The memory card is formatted as a portable storage, not as an internal memory.
  • 🔹 There is not enough free space on the map (at least) 10-15% volume-based).

Done: 0 / 4

3. Transfer applications over ADB (for power users)

If the standard method didn’t work, you can use Android Debug Bridge (ADB), a debugging tool that lets you manually tell the system which apps you can move, which requires connecting your smartphone to your computer and basic command line knowledge.

cmd

adb devices

(Your device name should appear – if not, check the drivers)

adb shell pm set-install-location 2

(This causes the system to default to install applications on SD-map)

adb shell pm get-install-location

(test: if the answer 2[external], It was a success).

Important: After running pm set-install-location 2, all new applications will be installed by default on the SD-The existing programs will have to be manually transferred through the settings or re-installed.

⚠️ Note: Some apps (such as Google Play Store or Mi Account) after transferring through the ADB If the smartphone starts to slow down or give out errors, return the settings with the command: adb shell pm set-install-location 0 (where 0 is the automatic selection of the installation location).

4.Use of SD-maps as internal memory

If you're willing to sacrifice the compatibility of the card with other devices, you can configure it as an extension of internal memory. SD-map as part of the main storage, and many applications can be installed on it automatically.

How to do this:

  6. After formatting, select Transfer Data to move some files and applications to SD-map.
What if the system does not allow you to format the card as an internal one?
If the option to Format as internal is inactive, check: - The card is not damaged (try formatting it on a PC in FAT32). - The card size is at least 8 GB (on smaller volumes Android can block this feature). - The smartphone has the latest version of MIUI (in old firmware, the option could be disabled). If nothing helps, try using a card from another manufacturer (for example, SanDisk or Samsung instead of no-name).

5. Manual transfer of cache and application data

Even if the application itself cannot be transferred to SD-card, you can often move its cache or data (for example, uploaded maps in Google Maps or media files in Telegram:

Alternative methods: Link2SD and App2SD

If the built-in methods did not help, you can use third-party utilities, such as: Link2SD or App2SD. These programs create symbolic links, allowing you to “cheat” the system and make it see the application files on the system. SD-map.

How to use Link2SD:

  1. Install Link2SD from Google Play.
  2. Give the application root rights (if any) or use a no root mode (less effective).
  3. In the main menu, select the application you want to move.
