Memory Cleanup on Xiaomi Redmi Note 7: a complete guide with hidden chips MIUI

Xiaomi Redmi Note 7 is still one of the most popular budget smartphones due to the balance of performance and price. However, even 64 or 128 GB of internal memory over time are filled with unnecessary files, app cache and duplicate photos. If your phone starts to slow down, issue notifications about space shortages or refuse to install updates, it’s time to clean up.

In this article, we will discuss not only standard ways to free up memory (which everyone knows), but also hidden functions. MIUI, You'll learn how to safely remove system debris, transfer applications to a root-free memory card, and why you clean through Settings. → Storage is often inefficient, and how to avoid the most common mistakes that cause users to lose important data.

Important: The methods are suitable for other models Redmi/POCO base MIUI 12–14, But some menu items may be slightly different. 7 Pro or Global Firmware – Check the relevance of the paths in the settings.

Diagnosis: Why does memory end so quickly?

Before you clean it, you have to figure out what's taking up space. Redmi Note 7 has a built-in storage analyzer, but it doesn't show everything.

• 📸 High-resolution photos and videos: one photo at 12 MP weighs ~3-5 MB, and a minute of video in 4K — up to 300 MB. with active use of the camera for a month can run 10+ GB.
• 🎮 Cash games and social media: PUBG Mobile, Genshin Impact or TikTok store up to 2-3 GB of temporary files for fast download.
• 📱 Systemic debris MIUI: Error logs, memory dumps, backups of updates - up to 1–1.5 GB in the section /data/log.
• 📁 Hidden application folders: messengers (Telegram, WhatsApp) and cloud services (Google Drive, Mi Cloud) download files in the background.
• 🔄 Duplicates and undeleted files: after updates or resets, “dead” folders remain in the folders. /storage/emulated/0.

To see the full picture:

1. Open the settings → About the phone → Storage.
2. Put it on the memory usage schedule.
3. Select a category (such as “Apps” or “Multimedia”) and sort by size.

Lifehack: If there's a folder on the list Android/obb A few gigabytes is a game cache that you can clean up safely (games will just reload the data the next time you run it) and here's a folder. Android/data Do not touch - there are saves games and settings.

2. Standard cleaning: what can be done without root rights

Let's start with basic methods that don't require any special knowledge, and they can free up 3 to 7 GB of memory in 10 to 15 minutes.

Clearing the application cache

Cash speeds up programs, but it grows into ridiculous sizes over time. MIUI There are two ways to clean it up:

• 🧹 Selectively: Settings → Annexes → Application management → select the application → Warehouse → Clear the cache.
• 🚀 Massive: Settings → Warehouse → Clear (button at the bottom of the screen).

Important: Do not clear the cache for Google Play Services, Mi Account, and system applications – this can lead to sync errors.

2.2. Delete unnecessary files through the “Cleaner”

V MIUI There is a built-in security tool → The cleaner who finds:

• 🗑️ Garbage files (temporary data, empty folders).
• 📂 Large files (>50MB).
• 🔍 Duplicate photos and documents.

How to use:

1. Launch Security → Cleaner → Deep cleaning.
2. Check the categories for scanning.
3. Click Clean and confirm the action.

💡

If the cleaner doesn’t find duplicate photos, try third-party apps like Files by Google or CCleaner, which often do better than built-in tools.

2.3. Transfer of applications to a memory card

The Redmi Note 7 supports microSD cards up to 256GB, but not all apps can be ported.

1. Insert a memory card (preferably) UHS-I Class 10 for speed).
2. Go to Settings → Applications → Application Management.

Limitations:

• ❌ You cannot transfer system applications (Mi Home, Security).
• ❌ Some games (PUBG, Call of Duty Mobile Blocks Transfer.
• ⚠️ After the transfer, the application may work slower.

Format the card as an internal storage (settings) → storage → map SD → three-point → storage settings → memory)

Backup important data from the card

Check the free space on the map (need 1.5-2 times more than the weight of the application)

Reboot the phone after the transfer-->

3. Advanced Cleaning: Hidden Functions MIUI

Now, let's move on to methods that few people know about, which require precision, but allow you to free up up to 2 to 5 GB of extra space.

3.1. Clearing the folder. /data/log (system-log)

MIUI It keeps detailed logs of the system that are rarely needed:

1. Connect your phone to your PC and enable debugging. USB (Settings → The phone. → Version. MIUI → tap 7 times → Return to the Additional Settings → For developers → Debugging by USB).
2. On the PC, install it. ADB Tools (download from the official Android website).
3. Open the command line in the folder with adb.exe and type: adb shell su rm -rf /data/log/* exit exit

Warning: this method requires superuser rights. Without them, the command won't work. If you don't have root rights, skip this paragraph.

Removal of old updates MIUI

After updating the firmware in memory remain files of the old version (update.zip). They can be removed manually:

1. Open any file manager with access to root folders (such as MiXplorer or Solid Explorer).
2. Move to the /data/ota_package.
3. Delete all files with the.zip extension.

If the folders /data No, that means you don't have root rights. Alternative: Use Settings. → The phone. → Updating the system → Three points. → Remove the downloaded package.

3.3 Cleaning up the Google Play Services cache

2. Find Google Play Services → Storage → Clear the cache.
3. Don't click Clear Data! This will cause your Google account to sync to failure.

4.Working with multimedia: how to make room without losing photos

Photos and videos usually take up the lion's share of memory, but you don't have to delete them -- there are ways to compress, optimize or migrate without loss.

4.1 Automatic optimization through Google Photos

If you are using Google Photos:

1. Open the app. → Profile → Settings → Make room.
2. The app will find photos and videos that have already been uploaded to the cloud and prompt you to delete local copies of them.
3. Confirm the action – this will free up to 50-70% of the space occupied by multimedia.

Before deleting, check that the files have actually been uploaded to the cloud (the cloud icon must be green).

4.2. compression of photo without loss of quality

You can reduce the weight of the photo by 2-3 times without any visible loss of quality:

• 📱 Through MIUI Gallery: Open the album → Choose a photo → More. → Squeeze.
• 💻 On PC: use RIOT FileOptimizer for packet compression.

Example: Photo from Redmi Note 7 (12 MP) ~4 After compression in the Gallery, its weight will decrease to 1–1.5 MBT while retaining permission 4000×3000.

4.3. transfer the photo to a memory card or cloud

If you have a microSD:

1. Open the Gallery → select the album → More. → Move it.
2. Specify the folder on the memory card (for example, DCIM/Camera).

For cloud services:

• 🌥️ Mi Cloud: Settings → Accounts. → Mi Cloud → gallery → Synchronize.
• 🌥️ Google Photos: Enable autoboot in the app settings.

💡

Don't just store your original photos in the cloud! Periodically download backups to your PC or external drive. In 2023, Google Photos stopped providing free unlimited storage, and Mi Cloud only gives 5GB.

5.Memory Cleansing Through Recovery: When Nothing Helps

If the phone is full and doesn't respond to standard methods, you can use recovery mode. It's a last resort, but it's guaranteed to make room.

Cache reset (wipe cache partition)

This operation deletes temporary system files without losing personal data:

1. Turn off the phone.
2. Press the Power button + Volume up until the Mi logo appears.
3. In the recovery menu, select Wipe & Reset → Wipe Cache (use volume buttons for navigation, power button for confirmation).
4. After cleaning, restart the phone (Reboot → System).

This method helps if the phone is slowing down due to overcrowded cache, but does not solve the problem of lack of space for user files.

5.2. Hard discharge (factory reset)

If you want to free up the maximum space, but you are ready to lose all data:

1. Make a backup of important files (photos, contacts, messages).
2. Go to recovery (as in the previous paragraph).
3. Choose Wipe & Reset → Wipe All Data.
4. Confirm the action and wait for the reboot.

⚠️ Warning: After a hard reset, the phone will return to factory settings, all apps, photos, messages and accounts will be deleted, and if you don't back up, it won't be possible to restore data!

Alternative: If you don't want to lose data, try transferring it to your PC and then reset it. After you set up your phone, copy the files back.

6.How to prevent memory filling in the future

To avoid clearing your memory every couple of months, set up the Redmi Note 7 to auto-optimize:

• 🔄 Autocleaning the cache: Settings → Warehouse → Automatic cleaning (enable and set a schedule).
• 📸 Photo quality restriction: in camera settings, select 9 MP resolution instead of 12 MP – this will reduce the weight of the photo by 30%.
• 🎮 Game cache restriction: on Google Play, disable auto-update games or set a traffic limit.
• 📂 Regular Storage Check: Launch Security once a month → Cleaner.

Also useful:

• 🚫 Remove unnecessary system applications through Settings → Annexes → Application management → Delete (e.g. Mi Music, Mi Video, if you don't use them).
• 🔍 Use the file manager to find large files: Settings → Warehouse → Files. → Sort by size.

💡

The most common mistake users make is to ignore notifications of memory shortages, so when less than 10 percent of storage is available, the phone starts to slow down, and the system creates even more garbage, optimally keep 15 to 20 percent of memory free.

7. Frequent mistakes and how to avoid them

Many Redmi Note 7 users make the same mistakes when cleaning up their memory.

Another common problem is that after cleaning, the memory is refilled in a few days, and it's because of:

• 🔄 Automatic download of application updates.
• 📥 Background synchronization of messengers (Telegram, WhatsApp).
• 🎵 Download music and podcasts in offline mode.

Solution: Turn off autoload media in the messenger settings and limit the background activity of applications in Settings → Battery → Energy management.
