Where does memory disappear on Xiaomi Redmi 6A: a full analysis of the causes and solutions

Xiaomi Redmi 6A is still one of the most popular budget smartphones due to its reliability and low price. However, many users face a common problem: the memory on the device melts like snow in the sun, despite the fact that you almost never installed anything. At one point, the system gives a notification: "Not enough space", although yesterday everything was fine. Why is this happening and where does the memory on the Redmi 6A go?

The fact is that the smartphone is equipped with only 16 GB of internal memory (of which the user has about 10-12 GB), and the operating system MIUI actively uses cache, temporary files and background processes, to which are added updates, debris from applications and hidden data, which results in even after removing photos and videos, no free space is added. In this article, we will analyze all possible reasons and give specific solutions to free up memory without losing important data.

1. MIUI system cache and garbage: the main "eater" of memory

The main reason Redmi 6A memory disappears “by itself” is the automatic cache accumulation of the system and applications. MIUI actively caches data to speed up work, but does not always clean it correctly. For example, after watching videos on YouTube or TikTok, temporary files can remain in memory for weeks, taking up hundreds of megabytes.

In addition, the MIUI shell itself backs up settings, log files and analytics data, and as a result, after a month of use, the free space is reduced by 1-2 GB for no apparent reason. On the Redmi 6A with 16 GB of memory, system debris can take up up to 30% of the total volume, which is critical for a budget device.

• 📱 Application cache – temporary files that should be deleted automatically, but often remain.
• 🗑️ Log files MIUI — Error logs and reports that the system collects for diagnosis.
• 🔄 Residual data – files from remote applications that are not completely cleaned.
• 📊 Usage statistics — MIUI It also takes into account the activity that takes place.

⚠️ Cache can be cleaned without consequences, and deletion of application data (for example, in WhatsApp or Viber) will lead to loss of chats and media files.

2. Hidden files and folders: what takes up space but is not visible in the gallery

Many users are surprised, "I deleted all photos and videos, and the memory is not free!", the fact that Redmi 6A has hidden system folders that do not appear in the standard file manager.

• 📁.thumbnails – thumbnails of images and videos (can weigh 500MB)+).
• 📁 DCIM/.thumbnails — gallery-cash.
• 📁 Android/data — Application data that is not always deleted when uninstallation.
• 📁 MIUI/backup — backup copies of settings and SMS.

To see these folders, you need to enable the display of hidden files in the file manager (for example, in ES Explorer or Total Commander).

1. Open the file manager.
2. Go to Settings. → Show hidden files.
3. Review the.thumbnails, Android/obb and Download folders.

3. MIUI Updates and Duplications of Files

Xiaomi regularly releases updates for MIUI, but few people know that each update saves the old version of the system in the memory of the device. On Redmi 6A, this can take up to 1-1.5 GB! In addition, when upgrading through OTA (over the air), the full firmware package is loaded, which is then not always deleted automatically.

Another problem is duplicate files, for example, when you transfer a photo from a computer or after you restore it from a backup, you can get copies of the same images with different names, and MIUI sometimes creates duplicate contacts, notes, and even SMS.

⚠️ Note: Do not delete files from the folder /system manually - this can cause system failure! To clean old updates, use only standard tools MIUI.

4. Apps that “inflate” over time

Some programs take up more space over time than they do when you install them.

• 📱 Facebook and Instagram cache stories, videos and photos, taking up to 1 GB+.
• 🎵 Spotify or Yandex Music – download songs to cash even in online mode.
• 🎮 Games (e.g., games, PUBG Mobile or Free Fire – save maps and textures in the Android/obb.
• 📱 Telegram – by default downloads all media files from chats.

To control such applications:

1. Go to Settings → Applications → Application Management.
2. Select the app and click Storage.
3. Click Clear Cache (not data!).
4. For games, check the Android/obb folder – there may be files weighing 1-2 GB.
