Lack of memory Xiaomi Redmi: how to free up without losing data

Xiaomi Redmi smartphone owners often face an annoying notification: “Not enough memory,” and the problem even occurs on devices with 64 or 128 GB of internal storage. What’s the matter? The fact is that MIUI actively uses cache, temporary files and duplicate data, which over time occupy gigabytes of space, and many applications (especially messengers and social networks) save media files in the background without asking permission.

But don't rush to buy a new phone or reset your settings to factory. 90% of the time, you can solve the problem with software methods without losing photos, contacts or installed apps. In this article, we'll discuss 7 working ways, including hidden MIUI features, that will help you free up 2 to 15 GB of memory on your Redmi Note 10/11/12, Redmi 9/10/11 or any other model of the series. All methods are tested on current versions of firmware (including MIUI 14 and HyperOS).

1. Cleaning cache and junk files through built-in tools

The first thing you should do is use the built-in MIUI cleaner, which removes temporary files, residual data from remote applications, and cache of system processes. With Redmi with MIUI 12+, the cleaning algorithm is smarter: it analyzes which files can be safely deleted without risking system stability.

How to start cleaning:

1. Open the Settings → Memory.
2. Slip the "Clean" button in the "Junk Files" section.
3. Wait 10 to 30 seconds for the system to scan the storage.
4. Click "Clean [X MB/GB]" (where X is the volume of debris found).

Tip: If the cleaning button is inactive or finds less than 100MB of garbage, go to Settings → Applications → App Management and manually clear the cache for the most voracious programs (for example, Facebook, Telegram, TikTok).

💡

After cleaning the cache, restart the phone - this will help the system correctly recalculate the free space and avoid "phantom" busy gigabytes.

2. Removal of duplicates and unnecessary media files

One of the main memory eaters on Xiaomi Redmi is duplicate photos and videos.

• 📸 Automatically save photos in Google Photos and Gallery at the same time.
• 🔄 Synchronization with cloud services (Mi Cloud, Yandex.Disk).
• 📱 Transfer files between devices via Mi Share or Bluetooth.
• 🎮 Screenshots and screen recordings (especially in games like Genshin Impact or PUBG Mobile).

To find and remove duplicates:

1. Open the Gallery app (or Photos in MIUI 14+).
2. Slip on three dots in the upper right corner → "Management" → "Dublicates".
3. The system will show groups of identical files. Select the ones that are unnecessary and click "Delete".

For deep cleaning, use third-party utilities like Files by Google or CCleaner, which not only find duplicates, but also:

• 🎬 Unseen videos (fragments left over after pruning).
• 📁 Empty folders.
• 📄 Zero-size files.

3. Transfer applications to a memory card (if supported)

Many Redmi models (e.g. Redmi) 9A, Redmi 8) supports microSD cards up to 512 GB, but by default, the applications are installed in internal memory. SD-map:

Important: not all applications can be ported, system utilities and some games (such as Call of Duty Mobile) will remain in internal memory. SD-cards slower than with the built-in drive – this can affect performance.

Instructions for transfer:

1. Insert the memory card (format it as internal memory in the settings if you want to port applications).
2. Go to Settings → Applications → Application Management.
3. Select the application → “Storage” → “Change” → “Memory card”.

⚠️ Attention: if you extract SD-The card will stop working after the application is moved, and it's also not recommended to use cheap memory cards in the lower class. A1 — It'll lead to lags and errors.

4. Cleanup of downloads and temporary files

The Download folder is a real dump of unnecessary files.

• 📄 Documents from messengers (WhatsApp, Viber).
• 🎵 Music and audiobooks downloaded for later".
• 📦 Archives (.zip,.rar) after unpacking.
• 🖼️ Images and GIFs from social networks.

How to clean:

1. Open the Files app (or Explorer).
2. Go to the Downloads section.
3. Slip on three points → “Sort” → “Size” (to show the largest files first).
4. Select the unnecessary and press "Delete".

Tip: To avoid the accumulation of garbage in the future, set up automatic cleaning of downloads.

1. Open Files → Three Dots → Settings.
2. Turn on the “Auto Clean” option and set a period (e.g. once a month).

5. disable automatic media saving in messengers

Messengers are the main source of quiet memory filling, for example, Telegram defaults all received photos and videos to the folder Telegram Images, and WhatsApp – WhatsApp Media. In a year of active use, these folders can take 10-30 GB.

How to turn off auto-saving:

On Telegram:

1. Open Telegram → Settings → Data and memory.
2. In the “Media Autoboot” section, select “Never” for all types of networks (mobile, Wi-Fi, roaming).
3. Slip "Clear Cache" at the bottom of the screen.

On WhatsApp:

1. Open the chat → tap on three points → “Media, links and docks”.
2. Select unnecessary files and click on the basket.
3. To disable autosave: Settings → Storage → Storage Management → disable “Save incoming media”.

⚠️ Warning: Once autosave is disabled, new media files will not automatically appear in the gallery. To save a photo or video, you will have to do it manually (long press on the file). → "Save").

6.Use of cloud storage and backups

If the phone is critically space-consuming, but you don't want to delete files, move them to the cloud. Xiaomi offers its own solution - Mi Cloud (5 GB for free), but there are more capacious alternatives:

• ☁️ Google Photos – unlimited storage for compressed photos / videos (quality "High").
• ☁️ Yandex.Disk – 10 GB free, convenient synchronization with PC.
• ☁️ Mega – 20 GB free, data encryption.

How to transfer files to Google Photos:

1. Install the Google Photos app from the Play Market.
2. Open it and log in to your Google account.
3. Slip on the avatar → “Photo settings” → “Backup and synchronization” → turn on the switchboard.
4. Choose “High Quality” (unlimited space) or “Original” (from Google Drive quota).

Important: Once files are uploaded to the cloud, they can be deleted from your phone, but they will remain accessible through the app or web version of the service. For example, Google Photos has a Free Place feature that automatically deletes already downloaded media from the device.

7. Reset the recovery and Dalvik partition cache (for advanced)

If all of the above methods failed and the free space is less than 1 GB, the problem may lie in the system cache, cleaning it requires access to the recovery menu and is only suitable for users who are ready for experimentation.

Warning: Mistakes in recovery can lead to data loss or a build-up of your phone, and if you're not sure, skip this section.

How to clean up the cache in recovery:

1. Turn off the phone.
2. Press the Volume Up + Power buttons before the Mi logo appears.
3. In the recovery menu (English or Chinese), select Wipe & Reset → Wipe Cache.
4. Confirm the action and wait for the completion.
5. Reboot the device (Reboot).

1. In recovery, select Advanced → Wipe Dalvik Cache.
2. Confirm and restart the phone.

⚠️ Attention: if after cleaning the cache, the phone loads for a long time (5-10 minutes) - this is normal!
