Memory Cleanup on Xiaomi Redmi 4A: A Complete User Guide

Xiaomi Redmi 4A is still one of the most popular budget smartphones due to its reliability and simplicity. However, 16 GB of internal memory (of which the user can only access ~10 GB) quickly clogged with photos, app cache and system files. If your Redmi 4A started to slow down, issue notifications about memory shortages or suddenly close applications, it’s time to clean up.

In this article, you will find 7 proven ways to clean up memory, including hidden MIUI features that few people use, which can be deleted without risk and which should not be touched, even if they take up gigabytes, and focus on the cache of applications, duplicate photos and system logs that quietly eat up precious space.

Important: All methods are tested on Redmi 4A with MIUI 9-12 firmware. If you have custom firmware installed (like LineageOS), some menu items may differ. To check the firmware version, go to Settings → About Phone → MIUI version.

1. Analysis of occupied space: what exactly eats memory?

Before you start cleaning, you need to figure out which files are taking up space. MIUI has a built-in memory analyzer, but it doesn't always show the full picture. Here's how to get the exact data.

Open Settings → Memory. Here you will see a diagram of the memory distribution by category: Applications, Images, Audio, Video and Other. Click on each category to see the details:

• 📱 Applications: List of programs sorted by size. Pay attention to games (e.g., games, PUBG Mobile or Genshin Impact – They can weigh 2–5 GB each.
• 📷 Images: not only your photos are hidden here, but also screenshots, memes from messengers, uploaded pictures from WhatsApp or Telegram.
• 🎵 Audio: music, podcasts, voice messages, often found duplicate tracks or unnecessary ringtones.
• 🎬 Videos: social media videos, saved stories, YouTube cache or TikTok.
• 🗃️ Other: the most insidious category! It's where the logs, the temporary files, the Google Play Services cache, and the remnants of the remote apps hide.

If the built-in analyzer shows that the Other takes up 3+ GB, that's a signal to action.

• 🗑️ Google Play Services cache (can weigh up to 1GB).
• 📄 Logs of the system (/data/log).
• 🔄 Remains of updates (/cache).

2.Cache cleaning applications: safe and efficient

App cache is a temporary file that helps programs run faster, and over time it grows to incredible sizes, for example, Facebook or Instagram cache can take 500 MB-1 GB, and Google Play Services cache up to 2 GB!

You can clean the cache in two ways:

Method 1: Manual cleaning for individual applications

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Chrome or YouTube).
3. Click Clear Cache (not to be confused with Clear Data – this will delete all settings and accounts!).

Method 2: Mass cleaning of cache of all applications

1. Open Settings → Memory → Clear the cache.
2. Confirm action. This will delete the cache of all applications, but it will not affect personal data.

⚠️ Warning: After cleaning the cache, some applications (such as Google Maps or Spotify) will load longer on the first run.

3. Deletion of unnecessary files: photos, videos and duplicates

Photos and videos are the main memory eaters. 4A camera-wise 13 MP one photo in format JPEG borrower ~3–5 MB, and a minute video in Full HD — before 100 MB: If you actively use messengers, then in folders WhatsApp/Media or Telegram/Telegram Images can accumulate gigabytes of unnecessary files.

How to find and remove excess:

• 📁 folder DCIM: This is where you store all the photos and videos from the camera. Use Google Photos or Gallery. MIUI, to find duplicates (include sorting by date).
• 🤖 Messenger folders: go to the /storage/emulated/0/ And you can find the WhatsApp, Telegram, Viber folders, and they usually have Media, Images, Video subfolders inside them.
• 🔍 Search for large files: Use a file manager (such as Mi File Manager or Solid Explorer) and sort files by size!

💡 Useful tip: Google Photos has a "Free Space" feature (in the app menu) that deletes photos from your phone that are already uploaded to the cloud, but leaves thumbnails. This can free up 2-5 GB in a few minutes!

4. Cleaning system files: logs, dumps and update cache

MIUI creates many service files that are rarely deleted automatically, including:

• 📜 Logs of the system (/data/log) — They record errors and events. They can be deleted without consequences.
• 🗑️ Memory dumps (/data/tombstones) — Created when applications fail.
• 🔄 Cash updates (/cache) — patchwork.

To delete these files:

1. Install a Root Explorer (such as Root Explorer or FX File Explorer).
2. Go to /data/log and delete all files with the.log or.txt extension.
3. Clear the /cache folder (root rights required!).

⚠️ Note: Removing files from /data or /system If you don't have root experience, use an alternative method:

1. Go to Settings → About Phone → Memory → Storage.
2. Click Clear in the System Data section.

5. Transfer of applications to SD-card (if supported)

Xiaomi Redmi 4A Does not support expansion of memory through SD-Card as internal storage (Adoptable Storage is disabled in the MIUI). However, some applications can be transferred manually to the memory card:

1. Put it in. SD-card (class 10 is recommended or UHS-I speed).
2. Go to Settings → Applications → Application Management.
3. Select an app (such as Facebook or Messenger).
4. Press Warehouse. → Change. → choose SD-map.

⚠️ Limitations:

• 🚫 Not all apps support portability (for example, WhatsApp or Google Play Services remain in internal memory).
• 🐢 Annexes to SD-The card is slower, especially if the card is cheap.
• ⚠️ When you remove the map, the applications will stop working.

💡 Alternative: Use SD-card for storing media files (photo, music, video) for this in the camera settings (camera settings) → Storage room) select SD-map.

6.Reset to factory settings: a last resort

If all previous methods failed and the phone still slows down or gives out errors about memory shortages, then a full reset will be left, which will delete all data, including apps, photos, accounts and settings, so first:

How to reset:

1. Go to Settings → Additional → Recovery and Reset.
2. Select Settings Reset.
3. Confirm the action (a password may be required).
4. Wait for the reboot (it will take 5-10 minutes).

After the reset, the Redmi 4A will return to the “out of the box” state, but the performance will improve markedly – this is due to clearing fragmented files and resetting system settings.

⚠️ Note: If you used Mi Account for sync, after resetting, the phone may require you to enter a login / password from your Xiaomi account!

7.Memory optimization after cleaning

Cleaning up memory is only half the battle. To keep the Redmi 4A from getting hammered again, follow these tips:

• 📵 Limit the cache for social networks: in the settings of Facebook, Instagram or TikTok, turn off autoloading videos and photos.
• 🔄 Clean the cache regularly: put a reminder once every 1-2 weeks.
• 🗑️ Use the cloud services: Google Photos, Yandex Drive or Mi Cloud to automatically upload photos.
• 🚫 Remove Unused Applications: Check the List in Settings → Apps and remove what you haven’t used for more than a month.

💡 Useful tip: Install Files by Google app – it automatically finds unnecessary files (duplicates, old memes, big videos) and suggests you delete them.

💡

Regular cache cleaning and photo duplicate removal can free up to 3-5 GB of memory on Redmi 4A without compromising functionality.
