How to Clean Memory on Xiaomi Redmi 8A: From Cache to Deep Cleanup

Xiaomi Redmi 8A is one of the most popular budget smartphones, but its 16/32 GB of internal memory is quickly clogged with garbage, cache and unnecessary files. If your phone starts to slow down, issue a notification “Not enough memory” or refuse to install updates, it’s time to do a general cleaning. In this article, we will analyze 7 proven cleaning methods, from simple to radical, taking into account the features of MIUI and the hardware limitations of the Redmi 8A.

It’s important to understand that Redmi 8A doesn’t support microSD expansion as a primary drive (only as external storage), so cleaning up internal memory is the only way to get the phone back up. We won’t advise “remove all apps” or “buy a new phone” – instead, we’ll show you how to make the most of your existing resources, including the hidden features of MIUI 10/11/12.

1. Diagnosis: how much memory is occupied and what

Before you start cleaning, you need to understand what exactly takes up space on your Redmi 8A.

1. Open the settings → About the phone → Memory.
2. Wait for the analysis (it can take up to 1 minute).
3. Study the chart: usually the most space is occupied: 📁 Applications (including cache and data) 📷 Media files (photos, videos, music) 🗑️ System files (updates, logs, temporary data) 📄 Other files (downloads, documents, APK)

There is a hidden feature on the Redmi 8A with MIUI: the system can show incorrect memory usage due to file compression. To see real numbers, use third-party utilities like Files by Google or SD Maid (available in the Play Market), which will show, for example, that the DCIM/Thumb folder weighs several gigabytes, although it is displayed as empty in standard conductor.

2. Cleaning the application cache: a quick way

Cache is a temporary file that creates applications to speed up work. On Redmi 8A, the cache can take anywhere from 1 to 5 GB, especially if you are actively using social networks, messengers or games, and can be deleted without harming data.

Method 1: Clearing the cache for individual applications

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or YouTube).
3. Press Warehouse. → Clear the cache.

Method 2: Mass cleaning the cache of all applications

1. Open the Settings → Storage → Cleaning.
2. Click the app cache and confirm the deletion.

Delete the Google Play Services cache (can weigh up to 1GB)

Clear the MIUI System Launcher cache (accelerate the menu)

Check the Gallery cache (miniature photos take hundreds of MB)

Delete Download Manager (download residues)

-->

Warning: Don’t confuse Clear Cache and Clear Data! The second option will remove all the application settings (such as logins in messengers or progress in games).

💡

If the app is slower after cleaning the cache, that's OK, and the cache will recover after a few minutes of active use.

3. Removal of unnecessary files and debris

MIUI has a built-in garbage-search tool, but it doesn't always find all the files you don't need.

Step 1: Built-in cleaning utility

1. Go to the Settings → Storage → Cleanup.
2. Select Categories to Remove: 🗑️ Unnecessary files (remains of deleted applications) 📥 Downloads (APK, archives, documents) 🎵 Audio files (cache of music from social networks)

• 📁 folder Android/obb — cache of games (if games are deleted, these files are useless).
• 🗃️ folder MIUI/Backup — backups.

Attention. ⚠️: Don't manually delete folders Android/data or Android/obb, If you're not sure what they're doing, it can cause applications to crash.

4.Storage optimization: transferring files to a memory card

Redmi 8A supports microSD up to 512GB, but with limitations: you can’t transfer applications to a card (media only).

2. In the notification, click Setup → select Portable Storage (not “Inner Memory” as Redmi 8A does not support Adoptable Storage).

Step 2: Transfer files

• 🎵 Music: In the Music app, click on the song → Management → Move it.

2. Start the analysis of the cart → System logs.
3. Delete files older than 30 days (usually.log,.dump).
