How to Clean Memory on Xiaomi Redmi Phone Without Deleting Anything: The Complete Guide

The memory clog on Xiaomi Redmi is a problem that every second smartphone owner faces. But what if you don't want to delete photos, videos or apps? It turns out that MIUI has a lot of tools hidden in it that allow you to free up 1 to 5 GB of memory without losing personal data. In this article, we'll look at legal cleanup methods that are not written about in standard instructions, from deep cache optimization to shutting down system memory eaters.

The main difficulty is that Xiaomi actively uses background processes to speed up the interface, but they also eat precious megabytes. for example, miui.analytics can take up to 800 MB of log files, and the cache of Google Play Services easily grows to 1-2 GB. We tested all methods on models Redmi Note 10/11/12, Redmi 9/10 and POCO X3/X4 – the results in the table below.

It's important to understand that no one method will give you a magical "+10 GB", but a combination of 3-4 methods can return up to 30-40% of free space without deleting user files.

1. Deep Cache Cleanup: Hidden Folders and System Data

App cache is the first candidate for removal, but standard cleaning through Settings → Apps only touch surface data. Real garbage hides deeper:

• 📁 folder /data/log — Logs of the system are stored here (up to) 1 GB on old firmware).
• 🗑️ Google Play Services cache – can weigh up to 2GB, but doesn’t show up in the standard file manager.
• 🔄 Residual update files - after updates MIUI time-folders download_rom.

To clean them without risk:

1. Open Settings → About the phone and 5 times click on the MIUI version to activate the developer mode.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your phone to your PC, install Android Studio (or ADB Tools only), and execute the commands:

adb shell pm clear com.google.android.gms


adb shell rm -rf /data/log/*




adb shell rm -rf /cache/download_rom/*

⚠️ Warning: Do not delete files manually through Explorer - this could disrupt Google Services.The commands above are safe and approved by Xiaomi for diagnostics.

2. Disabling analytics and unnecessary system processes

Xiaomi collects a huge amount of telemetry, from app usage data to Wi-Fi connection information, which takes up to 1.5 GB and is constantly updated to turn them off:

1. Go to Settings → Privacy → Special Permits → Usage Data.
2. Turn off Use Data Send and MIUI Diagnostics.
3. In the same menu, find Advertising and deactivate Personalized Advertising.

Additionally, you can disable the background activity of system applications:

• 🛑 com.miui.analytics – analytics MIUI (up to 500MB of logs).
• 🛑 com.xiaomi.market - background updates to the Mi App Store.
• 🛑 com.miui.systemAdSolution – ad display module.

For this:

1. Install App Manager (no root required)
2. Find the listed applications and turn off background activity and Auto Start.

💡

After the analytics shutdown, restart the phone – this will apply the changes and free up an additional 200-300 MB by clearing the log buffer.

3. MIUI Optimization: Hidden Memory Saving Features

MIUI 12/13/14 has built-in deep cleaning tools that are not advertised, such as Deep Cleaning Security, which removes not only cache, but also:

• 🧹 Residual files APK after installation/deletion of applications.
• 🗃️ Duplicate files in the Download folders and DCIM.
• 📱 Unused language packs (can weigh up to 1 GB).

How to start:

1. Open the Security app (shield icon).
2. Go to the Cleanup. → Deep cleaning.
3. Click Scan and wait for analysis (may take 2-3 minutes).
4. Delete everything except the Downloads section (there may be important files).

⚠️ If photos from the gallery are missing after deep cleaning, check the.thumbnails folder in the root directory. MIUI Sometimes it is mistakenly referred to as garbage, but files can be recovered through DiskDigger.

4. Removal of language packets and unnecessary localizations

MIUI defaults language packs for all supported regions, from Arabic to Vietnamese. On the Redmi Note 11, this takes up to 700 MB, although 90% of users use only 1-2 languages.

1. Download Localize My App.
2. Select System Applications and find:

In each application, leave only the necessary languages (for example, Russian and English).

Reboot the phone.

⚠️ Note: Do not remove languages from com.google.android.gsf and com.android.vending apps – this could disrupt Google Play.

5. Cleaning up Google Play cache and Google services

Google Play Services and Play Market are Xiaomi’s main memory eaters, and their cache can grow to 3GB, but standard cleaning methods don’t touch deep data.

Method 1: Through Application Settings

1. Go to Settings → Applications → Application Management.
2. Find Google Play Services and click Storage → Clear Cache.
3. Repeat for Google Play Store and Google Play Services for AR.

Method 2: Resetting data (without deleting your account)

1. In the same app settings, select Google Play Services.
2. Click Storage → Delete Data (don’t be afraid – it won’t delete your apps!).
3. Confirm the action and restart the phone.

Once reset, the data will be automatically recovered, but the cache will be cleared, a method that frees up to 1.2 GB on devices with active use of Google services.

6. Optimization of background processes and auto-start

MIUI aggressively caches background processes to "fast-start" applications, but this eats up to 1.5 GB of RAM and 500 MB of memory.

Step 1: Limiting Auto Startup

1. Go to Settings → Applications → Permissions → Autorun.
2. Turn off auto-run for all applications except instant messengers and system services.

Step 2: Turn off background activity

1. In Settings → Battery and Performance → Battery Management.
2. Select Applications and set Restricted mode for each (except messengers and navigators).

Step 3: Set up Memory Protection (only for MIUI 14+)

1. In Settings → Memory turn on Memory Protection.
2. Choose Balanced or Memory Saving mode.

These actions will not only free up space, but also extend the battery life by 10-15%.

💡

Disabling auto-runs for 10-15 unnecessary apps can free up up to 800MB of memory and reduce battery consumption by 5-7% per day.

7 Hidden folders and debris after updates

After each update MIUI Temporary files remain in folders /cache and /data/ota_package. They can be safely removed:

Method 1: Through Recovery

1. Turn off the phone.
2. Press Volume Up + Power to enter Recovery.
3. Choose Wipe & Reset → Wipe Cache.
4. Confirm the action and restart.

It's actually available at ~85-90% of the volume claimed. For example, the Redmi Note 10 128 GB out of the box is available at ~112 GB.
