Memory Cleanup on Xiaomi Redmi 7: A Complete Guide to Freeing Up Place

Why is Redmi 7 slowing down and what does it have to do with memory?

Xiaomi Redmi 7, released in 2019, is still a popular budget device, but over time, many owners face slowdowns, sudden hang-ups and the message “Not enough memory” – often due to a full internal storage or overloaded RAM, and even with a microSD card, the system can slow down due to cache of applications or fragmented files.

The main symptoms indicating the need for cleaning:

• 🐢 Applications open long or suddenly close
• 📱 The phone is heating up for no apparent reason.
• 🔄 The screen "stutters" when scrolling the menu
• 🚫 Unable to install updates or new programs

In this article, we will discuss 5 proven ways to clean up memory on Redmi 7, from basic to radical. It is important to understand that some methods can delete personal data, so it is recommended to create a backup before starting.

Method 1: Cleaning the application cache manually

Cache is a temporary file that applications create to speed up work. Over time, they accumulate and take up gigabytes of memory. On Redmi 7 with MIUI 10/11/12, the cache is cleaned through the settings menu:

1. Go to Settings → Applications → Application Management
2. Select an app (like Google Chrome or Facebook)
3. Click "Clear Cache" (not to be confused with "Clear Data"!)
4. Repeat for all "heavy" programs (messengers, social networks, games)

For mass cleaning:

1. Go to Settings → Storage
2. Select "Cache Data"
3. Confirm the removal (the system will show the total amount of vacated space)

Cache of browsers (Chrome, Mi Browser)|Cash messengers (WhatsApp, Telegram)|Social media cache (Facebook, Instagram)|Cash cards (Google Maps, Yandex.Maps)-->

⚠️ Note: Do not clear the cache of system applications (e.g. com.android.systemui) – this can cause shell malfunctions MIUI.

This method is safe and doesn't delete personal data, but it has a temporary effect, and it takes additional steps to clean up the data.

Method 2: Delete unnecessary files through built-in cleaner

MIUI has a built-in cleaning tool that analyzes the system and suggests that you remove the garbage.

1. Open the Security app (shield icon)
2. Select the "Cleaning" tab.
3. Click "Scan" and wait for the analysis to be completed.
4. Check the category boxes for removal: 🗑️ Unnecessary files (remains of deleted applications) 📁 Duplicate files (repeated photos/video) 🔍 Large files (forgotten downloads, logs)

Clean up

Unlike manual cache cleaning, this method finds hidden files that a user would not normally see.Redmi 7, for example, often accumulates log files from Google services up to 1-2 GB in size, which are safely deleted through a cleaner.

💡

If the cleaner finds files larger than 500MB in the Download category, check the /storage/emulated/0/Download folder – forgotten archives and installers (APKs) often accumulate there.

Method 3: Transfer data to a memory card

Redmi 7 supports microSD up to 512 GB, but by default, applications and files are saved to internal memory.

For photos and videos:

1. Open the Gallery.
2. Select an album or individual files
3. Press "More" → Move it"
4. Indicate. SD-map

For applications (for part of the programs only):

1. Go to Settings → Applications
2. Select an app (such as Spotify or Netflix)
3. Press "Storage" → Change. → SD-map"

⚠️ Note: Not all applications support portability SD-System programs and most games (e.g, PUBG Mobile or Genshin Impact will remain in internal memory, and the speed of the class 10 card will be lower than the built-in eMMC 5.1 drive.

If the memory card is not determined:

• 🔄 Reboot the phone.
• 🔧 Check the format (should be) FAT32 exFAT)
• 🛠️ Format the card via phone (Settings) → Warehouse → SD-map → Format)

Method 4: Removing System Garbage Through ADB

For power users, there is a deep cleaning method through Android Debug Bridge (ADB), which allows you to delete files that are not available through the standard interface.

• 🖥️ Computer with Windows/Linux/macOS
• 🔌 USB-cable (original)
• 🛠️ Utility. ADB (download from the official website)

Step-by-step:

1. Enable Developer Mode on your phone: Go to Settings → About the phone 7 times click on "Version" MIUI"

USB debugging

Settings → Additional → For Developers

adb shell


pm clear com.miui.cleanmaster # Cleaning up the cleaner cache




pm clear com.android.providers.downloads # Clean up downloads




rm -rf /data/local/tmp/* # Delete temporary files

⚠️ Attention: Misuse of the right ADB It can cause data loss or system failure.Do not delete files in folders /system or /vendor — It'll knock out the phone!

Once you have completed the commands, restart the device, a method that frees up to 1-3GB of hidden debris, but requires caution.

Method 5: Reset to factory settings (last resort)

If the previous methods didn't work, and the phone is full, it's a complete reset, and it will delete all the data, including:

• 📱 Installed annexes
• 📷 Photos and videos (if not saved to the map)
• 👤 Accounts and settings
• 📄 Messages and Contacts (unless synced with Google)

How to perform the reset:

1. Create a backup through Settings → Additional → Backup
2. Go to Settings → About the phone → Reset settings
3. Select "Erase all data"
4. Enter your password (if set) and confirm

Once reset, the phone will reboot to its original state, a method that is guaranteed to free up all user memory but requires reconfiguration of the device.

💡

Resetting to factory settings is the only way to get performance back out of the box if the phone is clogged with viruses or corrupted files.

Additional tips for memory optimization

To avoid re-filling the memory:

• 📵 Limit the background activity of applications in Settings → Battery → Choice of battery mode
• 🚫 Turn off automatic download of media in messengers (WhatsApp, Telegram)
• 🔄 Regularly (once in) 1-2 Clean the Download folder from unnecessary files
• 📊 Use lightweight alternatives to heavy apps (e.g. Facebook Lite instead of the main client)

To monitor the free space, install the applications:

• Files by Google – Shows large and unnecessary files
• SD Maid – Deep cleaning of system debris
• DiskUsage – visualization of occupied space

On Redmi 7 with 2/3 GB of RAM and 32/64 GB of ROM, it is critical to leave at least 10-15% free space for stable operation. When the memory is filled by more than 90%, the system begins to slow down due to lack of space for temporary files.
