Memory Cleanup on Xiaomi Redmi 7: A Complete 2026 Guide

Xiaomi Redmi 7, with its modest 2/3GB of RAM and 16/32GB of internal storage, often faces space shortages. Even after switching to MIUI 14 (the latest supported version for this model), users note that the system begins to “brake” when filling up more than 80%. Unlike flagships, budget devices require regular “general cleaning” – otherwise you risk seeing the words “Insufficient memory” at the most inopportune moment.

In this article, we’ll look at 10 proven ways to clean up memory on Redmi 7, from standard MIUI tools to hidden features and third-party utilities. We’ll focus on the unique problem of this model: once upgraded to MIUI 12+, the system automatically reserves up to 3 GB of updates that are not cleared through normal settings, and you’ll learn how to safely delete unnecessary files without damaging the smartphone’s performance.

1. Diagnosis: How much memory is actually occupied?

Before you start cleaning, you need to understand what exactly takes up space on your Redmi 7.

1. Go to Settings → About the phone → Memory
2. Click on the "Inner Memory" graph.
3. Wait for the analysis to be completed (may take up to 2 minutes)

The system will show the allocation of memory into categories: Applications, Media Files, Cash and Other. Pay attention to the "System Data" section - if it takes up more than 5 GB, this is a sign of accumulated debris from MIUI updates.

An important nuance for Redmi 7: Due to the Qualcomm Snapdragon 632 chip, some of the memory is reserved for the /vendor partition (about 1.5 GB), which is not displayed in standard analysis, and can only be seen through ADB or applications like DiskUsage.

2. built-in MIUI cleaning tools

Xiaomi has integrated several memory management utilities into MIUI, and on the Redmi 7, they don’t work as efficiently as on new models, but they still help to free up 1-3 GB.

Cleaning through "Safety"

The fastest way is:

1. Open the Security app (shield icon)
2. Choose Cleaning → Deep Cleaning
3. Check all categories (especially “Residual Files” and “Large Files”)
4. Press Clean (may take 3-5 minutes)

What removes this tool:

• 🗑️ App cache (including hidden cache of Google Play Services)
• 📁 Temporary download files (section) /download)
• 🎵 Duplicate media files (only if they are completely identical)
• 📦 Residual files of remote applications (folder) /data/app-lib)

Manual control of application cache

Some apps (like Facebook or Telegram) can take up to 500MB of cache to clear it selectively:

1. Go to Settings → Applications → Application Management
2. Sort by size (click on the three dots in the upper right corner)
3. Select the app → Storage → Clear the cache

⚠️ Note: Do not clear the cache for Google Play Services, MIUI System and Android System WebView – This can cause malfunctions in Google services and system updates.

3. System garbage disposal (hidden MIUI files)

Redmi 7 accumulates specific debris that is not visible through standard tools.

• 📦 Update files (/cache/ota and /data/ota_package)
• 🔄 Logs of the system (/data/log — before 1 GB per month)
• 🎨 Cache themes for the design (/data/system/theme)
• 📡 Diagnostic files (/data/anr and /data/tombstones)

To remove them, you will need to enable debugging over USB and use ADB:

adb shell


su




rm -rf /data/ota_package/*




rm -rf /cache/ota/*




rm -rf /data/log/*




rm -rf /data/anr/*




rm -rf /data/tombstones/*

Alternatives for beginners: SD Maid (requires root rights) or Files by Google (free, but not all).

4.Storage optimization: What can be safely removed

On Redmi 7 with 16GB of memory, every megabyte counts. Here's what you can delete without risking to the system:

Professional advice: Use Storage Analyzer to visualize occupied space, and it will show the largest files and folders that are not visible in a standard Explorer.

5. Data transfer to SD-map (with limitations)

Redmi 7 supports microSD up to 512GB, but with important caveats:

• ✅ You can transfer: photos, videos, music, documents
• ❌ Applications cannot be transferred (except for individual data via Adoptable Storage)
• ⚠️ Limit: speed of reading/writing to a class map UHS-I into 2-3 less than in the internal memory

How to set up:

1. Put it in. SD-map (format) FAT32 exFAT)
2. Go to Settings. → Warehouse → SD-map
3. Select Format as internal memory (all data will be deleted!)
4. After formatting, select Transfer Data

⚠️ Note: After formatting SD-As internal memory, it cannot be read on other devices without full formatting, and Redmi 7 does not support Adoptable Storage for applications, you can only transfer media files.

6.Reset to factory settings: when justified

If you have less than 1GB of memory left after all the manipulations, and the system is slowing down, you should consider hard reset. On Redmi 7, this is done in two ways:

Through settings (soft reset)

1. Create a backup through Settings → Additional → Backup
2. Go to Settings → About the phone → Reset settings
3. Choose to erase all data
4. Confirm the action (you will need to enter a pattern lock or PIN)

Through Recovery (hard reset)

If the phone is not turned on or stuck on the logo:

1. Turn off the device.
2. Press Power + Volume Up for 10 Seconds
3. In the Recovery menu, select Wipe Data (Manage Volume Buttons)
4. Confirm the choice and wait for the completion

Critical information for Redmi 7: After reset via Recovery, the first download can take up to 20 minutes.Do not interrupt the process, even if the screen does not respond - this is normal for this model due to the slow 5.1 eMMC memory.

💡

Redmi 7 factory reset deletes ALL data, including files in internal memory, but does not affect the contents SD-cards (unless they have been formatted as internal documents).

7. Alternative methods: for advanced users

If the standard methods did not help, try:

7.1. Removal of pre-installed applications (without root)

Many MIUI system applications can be disabled via ADB:

adb shell pm uninstall -k --user 0 com.miui.analytics


adb shell pm uninstall -k --user 0 com.xiaomi.midrop




adb shell pm uninstall -k --user 0 com.miui.cloudservice

A full list of safe to remove packages for Redmi 7 can be found on the XDA Developers forum (Redmi 7 Debloat section).

Change of cache partition

For power users, you can reduce the size of the /cache partition (by default 500 MB) and reassign it to user data.

• Unlocked loader
• Installed TWRP
• Backup copies of EFS and modem

⚠️ Warning: Changing partitions incorrectly can cause a device to fail. Redmi 7 is especially risky to touch the vendor and odm partitions, as they contain drivers for the Snapdragon 632.

8.Prevention: How to avoid memory filling in the future

To avoid clearing your memory every week:

• 📵 Turn off automatic app updates on Google Play
• 📷 Set up auto-save photos in Google Photos and then delete local copies
• 🗃️ Use cloud services (Mi Cloud, Yandex Drive) to store documents
• 🔄 Regularly (once a month) clear the cache through Settings → Warehouse → Cache data.
• 🚫 Remove weather and news widgets – they constantly update the cache in the background

Hidden MIUI function: Turn on Light Mode (Settings → Special Options → Light Mode) It turns off animations and background processes, reducing memory consumption by 15-20%.

💡

If you shoot video frequently, change the camera resolution from 1080p to 720p – this will reduce the file size by 2-3 times without significant quality loss on the Redmi 7 screen (resolution 720×1520).
