How to Clean Memory on Xiaomi Redmi 7A Phone: The Complete Guide

Xiaomi Redmi 7A is still a popular budget smartphone, but its modest 16 or 32 GB of internal memory is quickly clogged with photos, apps and system debris. If your phone starts to slow down, issue notifications about space shortages or refuse to install updates, it’s time to do a general cleaning. In this article, we will discuss all the working ways to clean up memory on the Redmi 7A, including hidden MIUI features that few people use.

Redmi's main problem 7A — There is no microSD slot in some versions (depending on the region). Even if you have a memory card-enabled version, system files and applications take up the internal drive by default. SD-map, delete unnecessary files without harming the system and even disable pre-installed Xiaomi services that devour memory in the background.

1. Analysis of occupied space: what exactly is the memory?

Before we start cleaning, we need to understand which files are eating up precious megabytes. MIUI has a built-in memory analysis tool, but it's hidden in the back of the menu. Here's how to find it:

1. Open the settings (cog icon on the desktop).
2. Go to the About Phone section. → Warehouse.
3. Click on Internal Memory (or Device Memory in older versions of MIUI).
4. Wait for the analysis to be completed (it can take up to 1 minute).

The system will show you a diagram of how you categorize your memory into apps, photos/video, audio, cache, etc. And notice the System Data section, if it's more than 5 to 7 GB, it's a sign of a temporary file clogging.

The recommendations section at the bottom of the analysis screen is particularly useful, and here MIUI automatically suggests that you delete:

• 🗑️ Unnecessary APK-Files (remains after application installation).
• 📁 Duplicate photos (if you have backed up).
• 🎵 Unused audio files (downloads from messengers, voice messages).
• 📱 Cache of rarely used apps.

2. Delete cache and temporary files

The app cache is the main memory eater on the Redmi 7A. It is used to speed up programs, but over time it grows to a giant size, and you can clean it in two ways: selectively (for individual applications) or globally (for all at once).

Method 1: Clearing the cache for a specific application

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

Method 2: Mass cleaning of the cache (it is recommended to perform once every 1-2 weeks):

1. Open the Settings → Storage → Internal Memory.
2. Put the Cache Data on the item.
3. Confirm the cleaning in the window that appears.

Delete the cache of messengers (Telegram, WhatsApp)|Clear downloads from the browser|Remove thumbnails (folder.thumbnails)|Remove the old ones. APK-files from the Download folder-->

Warning: Don't confuse cache with app data!Cache clearing is harmless, and deleting data (Clear Data button) will reset the program settings and delete accounts.

⚠️ Warning: After mass cache clearing, some apps (like Google Maps or Instagram) will load longer when first run.

Transfer of data to SD-card (if supported)

If your Redmi 7A is equipped with a microSD slot (check the specifications of your model!), you can transfer some files to an external drive.

• 📱 Applications can only be ported partially (not all support this feature).
• 📷 Photos and videos are completely portable, but some programs (e.g., a gallery) may be slower.
• 🎵 Music and documents are transferred without restrictions.

How to transfer files to SD-map:

1. Insert a memory card (recommended class is Class 10 or UHS-I for speed).
2. Open Explorer (the folder icon on the desktop).
3. Select files (press your finger on the file → mark the rest).
4. Press More. → Move it → SD-map.

For the portability of applications:

1. Go to Settings → Applications → Application Management.
2. Select a program (e.g. Spotify).
3. Press Warehouse. → Change. → SD-map.

⚠️ Attention: Don't pull out SD-a card without prior Secure extraction (in notifications) this may result in data loss or file system damage.

4. Remove unnecessary apps and games

Xiaomi’s standard apps (e.g. Mi Video, Mi Music, Mi Browser) take up to 1-2GB of storage, although most users don’t use them, and fortunately some of them can be removed or disabled without rooting.

How to remove pre-installed applications:

1. Open Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner → Show all the applications.
3. Find an unneeded app (such as Mi Pay or Mi Community).
4. Click Remove (if the button is active) or Disable (if deletion is blocked).

If the Remove button is inactive, try disabling the app - this will free up memory and stop background processes. MIUI:

• 🎬 Mi Video (video player)
• 🎵 Mi Music (music player)
• 🌐 Mi Browser (browser)
• 💰 Mi Pay (payment application)
• 📖 Mi Reader (book reader)
• 🎮 Game Turbo (if you don't play)

💡

Before you delete system applications, back up Settings → Additional → Backup. This will help you restore them if something goes wrong.

How to remove games and user applications:

Games (especially heavy ones like PUBG Mobile or Call of Duty) can take up to 3 to 5 GB each to remove them without a trace.

1. Go to Settings → Apps.
2. Sort the list by size (click on three dots → Sort by size).
3. Remove the hardest games you haven’t used in a long time.
4. After deleting, check the Android/obb folder in Explorer – there may be game cache files (remove them manually).

5. Cleaning up garbage with third-party utilities

Built-in MIUI tools don't always handle deep cleaning. Third-party apps can be used for more thorough cleaning, but it's important to choose reliable ones so you don't run into viruses. The best options for the Redmi 7A are:

• 🧹 SD Maid (deep cleaning of system debris, requires root rights for full functionality).
• 🗑️ Files by Google (Simple interface, deletes duplicates and unnecessary files).
• 🔍 CCleaner (classic utility, but in the latest versions there are a lot of ads).
• 📂 Clean Master (not recommended – aggressive advertising and data collection).

How to use SD Maid (recommended option):

1. Download SD Maid from Google Play (or from the official website if you don’t have access to the store).
2. Start analysis (CorpseFinder looks for remnants of remote applications, SystemCleaner - system garbage).
3. Delete the files found (do not touch the System section if you are not sure!).
4. Restart your phone to apply the changes.

Alternative without root rights - Files by Google:

This Google app doesn’t require special permissions and it’s great to find:

• 📸 Duplicate photos and screenshots.
• 🎥 Large video files (over 100 MB).
• 📄 Unnecessary documents and APK.
• 🗃️ Empty folders.

If all previous methods have failed, and the phone still gives notifications of memory shortage, it is time to consider a complete reset. This is a radical way, but it is guaranteed to return the Redmi 7A to its original state. Before reset, make sure to back up all important data - after the procedure everything will be erased without recovery!

How to reset your phone to factory settings:

• 📱 All installed apps and games.
• 📷 Photos, videos and music (unless transferred to the SD-map).
• 📝 Contacts, SMS Call log (if not synced with Google).
• 🔑 Wi-Fi, Bluetooth and Account Settings.

💡

Resetting to factory settings is the only way to remove system debris that has accumulated over the years of use and is not cleaned by standard methods.

7.Memory optimization after cleaning

Once the space is cleared, it's important to set the phone up so that the memory won't clog up again. Here are some tips:

1. Disable the auto-update of applications:

1. Open Google Play → Settings → Auto-Update apps.
2. Choose Never or Only through Wi-Fi.

2. Set up the cache cleanup automatically:

• 📅 Make a habit of going to the Warehouse once a week and deleting unnecessary files.

3. Reconfigure the preservation of media files:

• 📸 On WhatsApp: Settings → Warehouse → Preservation of media → shut off the car download.
• 🎥 In Telegram: Settings → Data and memory → Autoboot media → Choose Never.

4. Use cloud services:

• 🖥️ Google Photos (unlimited storage for compressed photos).
• ☁️ Yandex Disk or Mail.ru Cloud (give free 10-20 GB).

💡

If you shoot video frequently, set the camera to record at 720p instead of 1080p. This will reduce file size by 2-3 times without severe quality loss.
