How to Free Memory on Xiaomi Redmi Note 7: Full Instruction with Proven Methods

Why Xiaomi Redmi Note 7 is fast running out of memory and what to do about it

Owners of Xiaomi Redmi Note 7 They often face a lack of space, despite the 32/64 GB of internal memory. The thing is, the system is MIUI reserve 6-8 GB is for your needs, and installed applications, cache and media files occupy the rest of the space at times faster than on flagships. 32 GB, where after updates and installation 10-15 Free applications remain critically small.

The main “eaters” of memory on the Redmi Note 7: Cache of applications (can take up to) 3-5 GB), duplicate photos (automatic backup in Google Photos) + Xiaomi gallery, residual files after deleting programs and system debris that MIUI It doesn't always clean automatically. It's supplemented with system updates (weighted to up to a maximum of one). 1.5-2 GB) and log files that are created when crashes, resulting in the user seeing a notification "Memory is full", although there are no obvious "heavy" files on the device.

12 proven ways to free up memory on Redmi Note 7 without root rights and loss of important data, including hidden features MIUI, We'll look at both standard methods (cache cleaning, file transfer) and little-known tricks like compressing system applications or disabling automatic backups.

1.Analysis of occupied space: what exactly eats memory

Before you start cleaning, you need to know exactly which files and applications take up the lion's share of memory. Redmi Note 7 has a built-in tool for this, but it's hidden in the depth of settings.

Settings → About the phone → Memory → Memory analysis

Here you will see a pie chart with the distribution of memory by category:

• 📱 Applications – weight of installed programs (including system)
• 📁 Files - documents, downloads, APK
• 📷 Media - photo, video, audio
• 🗑️ Cash - Temporary application files
• 🔄 Other - system data, logs, backup copies

Please note the “Other” section if it is more 2-3 GB is a signal of a buildup of system debris. Also check the weight of the applications: some games (such as Genshin Impact or Call of Duty Mobile) can weigh in on the weight of the app. 4-6 GB each, even if you haven’t played them in a while.

2.Cleaning the application cache: safe and efficient

Cache is a temporary file that apps create to speed up work, and over time, it grows to giant sizes, especially for instant messengers (Telegram, WhatsApp), social networks (TikTok, Instagram), and games. On the Redmi Note 7, the cache can be cleared in two ways:

Method 1: Manual cleaning for individual applications

Open the Settings. → Annexes → App management, select a program (like YouTube) and click Clear Cache. for mass cleanup:

Settings → Memory → Clean (in the "Cash" section)

Important: Don’t confuse Clear Cache with Clear Data – the second action will delete all settings and accounts in the app!

Method 2: Automatic cleaning on schedule

MIUI allows you to set up automatic cleaning of the cache:

• 🔄 Go to Settings. → Memory. → Settings (cogs at the top)
• 📅 Turn on the Auto Clean option and select frequency (weekly or monthly)
• 🗑️ Activate “Clean When Locked” – the cache will be deleted when the screen is turned off.

Select “Clear Cache” rather than “Clear Data”

Do not clear the cache of system applications (may cause crashes)

Check the weight of the cache in the Memory Analysis once a week

Use Auto Cleaning to Save Time-->

⚠️ Note: Do not clear the cache for Google Play Services apps, MIUI System or Security: This can lead to system errors, including push notifications and authorization issues in your Xiaomi account.

3. Removing unnecessary applications and “facilitating” system

The Redmi Note 7 preinstalled a lot of Xiaomi system apps that can’t be removed by standard methods, but can be disabled or compressed, such as Mi Video, Mi Music, Mi Browser and Google backup services (e.g., two calendars: from Xiaomi and from Google).

How to remove or disable unnecessary programs

List of safe applications to remove / disable:

• 🎵 Mi Music – if you use Spotify or Yandex Music
• 📺 Mi Video - if available VLC or MX Player
• 🌐 Mi Browser – if you prefer Chrome or Firefox
• 📅 Mi Calendar – if you sync with Google Calendar
• 📧 Mi Mail – when using Gmail or Outlook

To turn off:

Settings → Applications → Application Management → [select application] → Disable

To completely remove system applications (requires an unlocked bootloader), you need to ADB Without them, you just shut down, it frees up memory and stops background activity.

System Application Compression (Hidden Function) MIUI)

Little-known trick: MIUI It allows you to compress system applications, saving up to 30-50% For this purpose:

• 🔧 Turn on Developer Mode (7 times click on Version) MIUI» In Settings → The phone)
• 📦 Back to Settings → Additionally. → For developers and enable "Compression of system applications»
• 🔄 Reboot your phone, the process will take 5-10 minute

⚠️ Note: Do not compress the Google Play Services, Services Framework and MIUI System. This can disrupt Google services and push notifications, and after compression, some applications can run on the Internet. 1-2 second-long.

💡

Before disabling the system applications, check if you use their functions indirectly. For example, Mi Video is used to play video in the gallery, if you delete it, the clip in the photos will not play.

4. File transfer to memory card: nuances for Redmi Note 7

Redmi Note 7 supports microSD cards up to 256 GB, but data portability is limited. First, not all applications can be moved (especially system, MIUI The default is to store photos and videos in internal memory, even if the card is inserted.

Configure the saving of media files on the map

New photos and videos are automatically saved to SD:

Camera → Settings (cog) → Store location → Memory Map

For existing files:

• 📂 Open Explorer (or Google Files)
• 📷 Go to the folder. DCIM/Camera or Pictures.
• 🔄 Select the files → «Move it» → Select a memory card

Transfer of applications to SD-map

Not all apps support portability, but it’s worth trying:

Settings → Applications → [select application] → Memory → Change → Memory Map

Limitations:

• ❌ System applications cannot be moved
• ❌ Some games, for example, PUBG Mobile) block the transfer
• ⚠️ After the transfer, the application may work slower (SD-lower-class A1 Not optimized for this)

⚠️ Attention: If you extract SD-The card will stop working until it returns, and don’t use the card as internal memory (optional in settings) as this causes crashes after updates. MIUI.

5. Photo and video optimization: compression without loss of quality

Media files are the main memory eater on Redmi Note 7. One minute of video in 4K weight ~350 MB, and the photo's in mode. 48 MP - before 10-15 MB every one, MIUI and third-party tools allow you to compress them without any visible loss of quality.

Compression of photos via Google Photos

Google Photos offers unlimited storage for compressed photos (up to 16 MP) and videos (up to 16 MP) 1080p):

• 🗑️ After downloading, remove the originals from your phone (the option “Free space»)

Use of built-in compression in MIUI

Xiaomi Gallery can compress photos when exporting:

Gallery → Select a photo → More (three points) → Compress

Choose High (retains 80% of the original size) or Medium (up to 50% space savings).

Third-party tools for advanced compression

If you need to compress files more, try:

• 📱 Photo & Picture Resizer – compression to a given size (for example, up to 2 MB in the photo)
• 🎥 Video Compress – Reducing video resolution to 720p maintain acceptable quality
• 🔍 Files by Google – automatically finds and offers to compress large files

6. Cleaning up system debris and residual files

MIUI leaves behind a lot of unnecessary files: log files (.log), temporary update data (download_rom), Remnants of remote applications (lib folders) and duplicate media files, which will require both built-in tools and third-party utilities to remove them.

Built-in cleaning in MIUI

Launch Security (Shield Icon) → Cleanup → Deep cleaning. You can remove it here:

• 🗑️ Residual files (APK, OBB, update cache)
• 📄 Empty folders and temporary files
• 🔍 Duplicate photos (installation "Repeats»)

Manual cleaning through a conductor

Open the Explorer and manually remove:

• 📂 folder download_rom In the root of memory - here are stored old firmware
• 📄 Files with.log and.tmp extensions in folders Android/data
• 🎮 Folders. OBB and APK for remote games (e.g. com.tencent.ig for PUBG)

Third-party utilities for deep cleaning

For automated cleaning:

• 🧹 SD Maid – Finds and deletes residual files, empty folders, duplicates
• 🔍 Files by Google – offers to clear unnecessary files (including large unused apps)
• 📊 DiskUsage – Visualizes which folders occupy the most space

⚠️ Note: Do not manually delete files in folders MIUI, system or efs. This can cause the phone to break down. Android/obb For installed games, this will delete game data.

7. Disable automatic backups

MIUI By default, it creates backups of applications, settings and even SMS, what 1-2 GB of memory: Most users don't need it, especially if you don't plan on dropping your phone to factory settings.

To disable reservations:

• 📱 B Settings → Memory. → Find files with the.bak or.mbk extension
• ☁️ In Google Drive, delete the Backup folder (if sync was enabled)

💡

Turning off automatic backup frees up to 1.5GB of memory and speeds up the phone, as the system doesn’t have to constantly create copies of data.

8. Alternative methods: for advanced users

If the standard methods didn't work, try these methods. They take longer, but they give you a significant boost in space.

Reset to factory settings (last chance)

If the phone is full of unknown things, and free less than 1 GB, hard reset will help. Important: pre-copy all the data on a PC or memory card!

Settings → About the phone → Reset settings → Erase all data

After resetting, the phone will return to a “clean” state. ~20-25 GB of free space (for version) 32 GB).

Using ADB to Remove System Applications

To remove embedded applications (e.g. Mi Pay, Mi Credit) without root rights:

• 🖥️ Install. ADB on PC and connect the phone in debugging mode (Settings) → For developers → Debugging by USB)
• 📋 Execute the command: adb shell pm uninstall -k --user 0 com.xiaomi.payment (replace com.xiaomi.payment with the desired application package)

The list of system application packages can be found on the forums 4PDA or XDA Developers.

Transfer applications to the memory card through ADB

If the standard transfer does not work, use ADB:

adb shell pm move-package com.example.app /sdcard

(Replace com.example.app with the app package)

⚠️ Note: Removing system applications through ADB may disrupt MIUI, including update errors or interface failures. Before experimenting, back up with Mi PC suite TWRP (if established).
