Note that in Redmi Note 7 with MIUI 10-12, the path may be slightly different. If you don’t have Memory in About, try the alternative route: Settings → Applications → Application Management → Memory.

Hidden Memory Analysis Features: Engineering Menu and ADB

Few people know, but Redmi Note 7 has advanced memory diagnostic tools that are not available through the standard interface, one of which is an engineering menu that allows you to see detailed information about /data partitions and identify junk files that are not displayed in normal analysis.

To get there:

How to transfer applications to SD-The map (and why it doesn’t always work)

One of the most popular functions is the transfer of applications to SD-Redmi Note 7 has this option, but it works with reservations:

First, check if your device supports this feature:

1. Go to Settings → Applications → Application Management.
2. Select the appropriate application.

• ⚠️ After porting, the application may run slower due to read speed. SD-map.
• ⚠️ Some features (widgets, notifications) may stop working.

The alternative way is to use SD-Card as internal memory (Adoptable Storage function in Android:

1. Put it in. SD-map (preferably class) UHS-I U3 speed).
2. When a notification appears, select Use as internal memory.
3. Follow the instructions of the system (the map will be formatted!).

⚠️ Note: After formatting SD-The card as internal memory cannot be used in other devices without being completely cleaned, and it can also shorten the life of the card due to frequent recording operations.

Cache Cleaning: What Can Be Deleted and What Cannot Be Deleted

Application cache is a temporary file that is created to speed up its work, and over time, it can take up gigabytes of memory, but not all of it can be safely deleted.

Here’s what you can clean without risk:

• 🎮 Cash games (especially if you haven’t run them in a long time).
• 📷 Cash galleries and photo processing applications.
• 🌐 Cache of browsers (Chrome, Mi Browser).
• 📺 Cache of streaming services (YouTube, Netflix).

Here is what is not recommended to be removed:

• 🚫 Cache of system applications (com.android.systemui, com.miui.home).
• 🚫 Google Cache (com.google.android.gms).
• 🚫 Cache of applications for working with bank cards or payments.

To clean the cache safely:

1. Go to Settings → Applications → Application Management.
2. Select the app and tap Clear the cache.
3. For mass cleaning, use Settings → Memory → Clear the cache.

Choose apps that have not been used in a long time|Check the cache size (if less than 100MB, you can skip it)|Do not clean the cache of system services|Restart your phone after cleaning.-->

⚠️ Attention: Clearing the cache of Google Play Services or Mi Account can lead to authorization errors and push notification issues.If there are failures after cleaning, restart the device.

How to find and remove duplicate files

One of the main reasons for memory loss is duplicate photos, videos and documents, and MIUI has a built-in tool to find them, but it's hidden in a non-obvious place.

To find duplicates:

1. Open the Files app (folder icon).
2. Go to the Analysis tab (or Cleanup in new versions).
3. Select Duplicate File Duplicates.
4. The system scans the memory and shows groups of identical files.

For deeper cleaning, you can use third-party applications like Files by Google or CCleaner, but note:

• 🔍 These apps require storage access, which can be a privacy risk.
• 📁 They often find “false duplicates” (like similar photos with different resolutions).
• 🗑️ Delete files selectively, not in bundles, so you will avoid losing important data.

Pay special attention to the folders:

• DCIM/.thumbnails – there are thumbnails of photos that can be safely deleted.
• Download – often contains outdated APK-file.
• Android/obb is a game cache that can be cleared if the games are removed.

Optimizing Memory with Developer Mode

Redmi Note 7 has hidden settings for developers to allow more flexibility in memory management.

1. Go to Settings. → The phone.
2. Tap 7 times on the line version of MIUI.
3. You will see a message that you have become a developer.

• 📱 Inactive Apps – Shows a list of apps that can be disabled.

You can also enable USB Debugging, which will allow you to use ADB for deep cleaning, for example, the command:

adb shell pm trim-caches 1000M

Will forcefully clear the cache of all applications that occupy more than 1 GB.

⚠️ Warning: Turning on Do Not Save Action will cause all applications to close when they leave, which can be inconvenient if you switch between tasks frequently.

What to do if your memory is full and cleaning doesn’t help

If you delete all the files you don't need, if you clear the cache, but the memory is still full, it could be system processes or corrupted files.

1. Check hidden files and folders

Some applications (especially pirated or modified ones) create hidden folders that don't appear in standard Explorer to see them:

• Use a file manager with root access support (such as Root Explorer).
• Or connect your phone to your PC and enable the display of hidden files in Windows Explorer settings.

2. Reset the settings to factory

If the system files are the problem, a full reset will help.

Make a backup of contacts and photos|Write down logins/passwords from accounts|Make sure you know the details from the Mi Account (linked to the phone)|Out. SD-map, if used-->

For discharge:

1. Go to Settings → Additional → Recovery and Reset.

1. Connect your phone to a PC with USB debugging enabled.
2. Enter in the command line:

adb shell


su




rm -rf /data/log/*




exit




exit

4. Update firmware

Some versions of MIUI for the Redmi Note 7 had bugs that filled the memory with “junk.” Check for updates in Settings → About Phone → System Update.

💡

If the memory continues to disappear after all the manipulations, the problem may be the hardware wear of the flash memory, in which case only replacing the chip in the service center will help.
