How to increase memory on Xiaomi 7A: from garbage cleaning to 1TB memory card

Why Xiaomi 7A is running out of memory and what to do about it

Owners of Xiaomi Redmi 7A often face the problem of lack of internal memory โ€” especially if the device is used as the main smartphone for photos, instant messengers and games. the Basic version of the model is equipped with only 16 GB or 32 GB of ROM, of which the user is available 30-40% less due to preinstalled MIUI firmware and system files. Even after the transition to MIUI 14 or HyperOS, the situation does not improve โ€” modern applications are taking up more space.

The main memory eaters on Xiaomi 7A: app cache (especially Telegram, VKontakte, TikTok), residual files after deleting programs, duplicate photos (due to automatic backup in Google Photos), system updates that are downloaded in the background.

Without regular cleaning, the smartphone starts to slow down, and the notification "Memory is full. Clear up space" appears every 5 minutes.

In this article, we will analyze 6 working ways to increase memory on Xiaomi 7A โ€“ from basic (cleaning up garbage) to advanced (using a memory card as an internal drive). All methods are tested on current versions of MIUI and HyperOS, taking into account the features of the budget hardware of the smartphone (Snapdragon 439, 2 GB of RAM).

โš ๏ธ Warning: Do not clear the cache of system applications (MIUI System, Security, Google Play Store โ€“ this can cause malfunctions in the smartphone. Also, do not delete the Android folder in the root directory โ€“ it stores application data.

Once cleaned, restart the device. If there is 1-2 GB more free space, but the problem remains, move on to the next method.

Method 2: Transfer applications to a memory card (microSD)

The Xiaomi Redmi 7A supports microSD cards up to 512 GB (officially) and up to 1 TB (unofficially, with the risk of instability), and can be used in two ways: as portable storage (for photos, videos, music) or as internal memory (for installing applications).

microSDXC1 TBUHS-I (U3)Yes (possibly lags)

โš ๏ธ Note: When using a memory card as an internal drive: it cannot be removed without first "disabling" in the settings, the speed of applications will decrease by the time the memory is stored. 20-40% (Depending on the class of the card, some programs (for example, WhatsApp, Banking applications) are not ported to the card. SD.

๐Ÿ’ก

Before buying a memory card, check it for authenticity with H2testw (Windows) or SD Insight (Android).Fake cards often have understated write speeds, leading to lags.

Method 3: Use OTG-drive (flash drive or hard disk)

If you're in Xiaomi. 7A No memory card slot (or it's occupied by the second one) SIM-card, you can connect an external drive through OTG-Adapter. Smartphone supports: USB-flash-drive (FAT32/exFAT), external HDD/SSD (Additional power is required!, microSD card readers.

How to connect the OTG-drive:

๐Ÿ”น No limit on the volume (can be connected) HDD 2 TB).

๐Ÿ”น Read/write speeds are higher than microSD (if you use it) SSD).

๐Ÿ”น You can quickly transfer files between devices.

Cons:

๐Ÿ”ธ OTG-Adapter takes up the charging port (you canโ€™t charge your phone at the same time).

๐Ÿ”ธ Hard drives require external power supply (need a hub with a USB).

๐Ÿ”ธ Not all applications are able to work with OTG-storage.

Which flash drives work best with Xiaomi 7A?
Best results are shown by USB 3.0/3.1 flash drives and read speeds of 80MB/s (e.g. SanDisk Ultra Fit, Samsung BAR Plus). Avoid cheap no-name drives, which often overheat and cause errors when copying large files.

Method 4: Optimizing Storage with Cloud Services

If physical memory expansion is not possible, you can transfer some of the data to the cloud. Xiaomi 7A preinstalled services Mi Cloud (5 GB free) and Google Drive (15 GB), Alternatives are also available: Yandex Drive (10 GB), Mega (20 GB), OneDrive (5 GB).

How to set up automatic uploading of photos and videos:

๐Ÿ“ฑ Backups: Set up the save SMS Contacts in Mi Cloud (Settings) โ†’ Xiaomi account โ†’ Mi Cloud โ†’ Synchronization).

๐Ÿ’ก

Cloud services do not increase the physical memory of a smartphone, but they allow you to free up to 5-10 GB by transferring rarely used files there, the main drawback is that access to data requires the Internet.

Method 5: Removal of system applications (debloating)

Xiaomi 7A is loaded with pre-installed programs (bloatware), which take up to 1-2 GB and are not removed by standard means, these include: Mi Video, Mi Music, Mi Browser, GetApps, Facebook (in some regions).

You can delete them without root-rights, but you will need to debug via USB and a computer.

Instructions for debloating through ADB:

adb devices


adb shell




pm list packages | grep 'miui'




pm uninstall -k --user 0 com.miui.videoplayer # example for Mi Video

After debloating, restart the device and check the vacant space in Settings โ†’ Memory.

Method 6: Reset to factory settings (last resort)

If none of the methods worked and there was less than 500MB of free memory, there is a hard reset, which will delete all the data, including photos, messages and installed applications, but return the smartphone to its original state.

How to do the reset correctly:

  1. Back up your important data (via Mi Cloud or PC).
  2. Go to Settings โ†’ About the phone โ†’ Reset settings.
