Cleaning RAM on Xiaomi Redmi 7: from manual methods to hidden MIUI features

Why Redmi 7 is slowing down due to a lack of RAM and how to fix it

Your Xiaomi Redmi 7 is getting stuck when switching between apps, and games and messengers are constantly rebooting? The fault is filled RAM. The model with 2 GB of RAM (or 3 GB in the version of Redmi). 7A) Even standard tasks like watching YouTube and chatting on WhatsApp can lead to lags. MIUI aggressively caches background processes, and the weak Snapdragon 632 processor can not cope with multitasking.

Unlike flagships, Xiaomi's budget smartphones are not optimized for long run without cleaning RAM. The system itself tries to free up memory by killing processes, but often does so inefficiently - for example, closing the messenger instead of an unnecessary Mi Video service. As a result, you lose unsaved messages or progress in the game. Fortunately, there are ways to manually control RAM without installing questionable "boosters."

In this article, only working methods tested on Redmi 7 with MIUI 10-14 firmware, no universal tips like "buy a phone with more RAM" - only specific instructions tailored to the specifics of your model.

Method 1: Manual cleaning of RAM through the MIUI menu

The fastest and safest method is to use the built-in memory cleanup feature in MIUI, which doesn't require superuser rights and works even on locked bootloaders. Here's how to activate it:

1. Open Settings → Applications → Application Management.
2. Tap the icon of three dots (⋮) in the upper right corner and select RAM Cleanup.
3. A list of active processes will appear on the screen. Click Clear Everything (or select individual applications to close).

⚠️ Attention: Do not clean RAM too often, this can increase battery consumption. Every time you run an application, the system has to reload its data, which wastes additional energy. The optimal frequency is 1-2 times a day when you use it actively.

Save important data in open applications (e.g. draft messages)

Close your auto-save games (like PUBG Mobile or Genshin Impact)

Disconnect from important calls (cleanup may interrupt the connection)

Check the battery level (process consumes) ~1-2% charge)-->

If the RAM Cleanup button is not on the menu, then your version of MIUI is hiding it.

1. Hold the menu button (or swipe up from the bottom edge of the screen and hold it).
2. In the multitasking window that opens, tap the basket icon (or the words Clean Everything).

Method 2: Disabling Auto-Run Unnecessary Applications

Many programs (especially from Xiaomi and Google) run automatically when you turn on your phone or connect to the Internet. They take up RAM even if you are not using them. For example, Mi Browser, Mi Music or Google Play Books can consume up to 100-200 MB of RAM in the background.

To prohibit auto-start:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Mi Video) and tap AutoRun.
3. Turn off the slider Allow Auto Start.

For mass shutdown, use the filter:

• 🔍 System Applications: Leave only Settings, Phone and Messages enabled.
• 📱 Social media: Turn off auto-run for Facebook, Instagram - they already consume a lot of RAM.
• 🎮 Games: All without exception (even Candy Crush can run in the background to update events).

Social networks (Facebook, Instagram)

Messengers (WhatsApp, Telegram)

Games (PUBG, Free Fire)

System Services (Miui Daemon, Google Play Services)

Others-->

⚠️ Note: Do not disable Autoplay for Google Play and Miui Daemon Services – this may lead to sync errors (no notifications will come, geolocation will stop working).

Method 3: Limiting Background Application Activity

Even after disabling autorun, some programs continue to run in the background, consuming RAM. MIUI has a hidden setting to limit background activity for individual applications, which will reduce their impact on performance, but can disable notifications.

Instructions:

1. Go to Settings → Battery and Performance → Battery Management.
2. Select an app (such as Telegram) and set the Restricted mode.
3. For aggressive optimization, select Strict Mode (but notifications will arrive with a delay).

💡 Useful tip: For instant messengers (WhatsApp, Viber) choose Limited mode - so notifications will come almost without delay, and RAM will be saved.

Method 4: Using Light Mode (Lightened Firmware)

Xiaomi hides a special mode in the settings "Light", which optimizes the system for weak devices like Redmi 7, it turns off animations, reduces the consumption of RAM and speeds up the interface.

1. Open the Settings. → The phone.
2. Tap 7 times on the line MIUI version until the message appears You became a developer!
3. Return to the main settings menu and open Additional → for developers.
4. Find the option Light Mode and turn it on.

After the reboot, you will notice:

• ⚡ Quickly open applications (by disabling background processes).
• 🔄 Less lag when switching between tasks.
• 📉 Reduced RAM consumption by 15-20% (based on tests on Redmi 7 with 2 GB of memory).

⚠️ Note: Some functions will stop working in this mode MIUI, for example:

• Automatic theme (you will have to choose manually).
• Dynamic wallpaper.
• Voice assistant Xiao AI (if you have one installed).

Method 5: Clean RAM through an engineering menu (for advanced)

If standard methods don't work, you can use the Engineering Mode, which gives you access to hidden Qualcomm settings, including forced memory cleanups, and be careful, if you do something wrong, you can crash.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that opens, select Usage statistics.
3. Put the clear memory (clear memory) on.

This method cleanses RAM at the Android kernel level, so it is more effective than the standard MIUI function. However, after using it, some system processes can restart longer than usual (up to 10-15 seconds).

💡

If the engineering menu doesn't open, try entering the code through the Google Phone app (download it from Play Market).The standard Calls app from Xiaomi sometimes blocks service combinations.

⚠️ Note: Do not change other options in the engineering menu, especially in Battery information or Network testing:

• Reduce the battery to a quick discharge (if you change the power consumption parameters).
• Disrupt the mobile network (if you edit the settings of the Snapdragon module).

Method 6: Removing System Garbage Through Safe Mode

Sometimes RAM is clogged not only by user applications, but also by system debris — update remnants, MIUI cache, temporary kernel files. They can't be deleted in normal mode, but can be cleaned through Safe Mode.

How to run Safe Mode on Redmi 7:

1. Turn off the phone.
2. Hold the Power button until the Redmi logo appears.
3. Once the logo disappears, immediately press and hold the Volume Down button until the phone boots up.
4. In the lower left corner of the screen should appear the inscription Safe mode.

In safe mode:

• 🧹 Clear the cache: Settings → Memory. → Clear the cache.
• 🗑️ Remove unnecessary APK: Check the folder. /sdcard/Download For the presence of old update files (update.zip).
• 🔧 Reset application settings: Settings → Annexes → Reset application settings (this won’t delete data, but will clear temporary files).

After cleaning, restart the phone as normal. RAM should be free of 200-400 MB (depending on the amount of garbage).

💡

Safe mode does not delete personal data (photos, contacts, messages), but temporarily disables all third-party applications, which helps to determine which one consumes the most RAM in normal mode.

Method 7: Optimization MIUI assisted ADB-teams (no teams) ROOT)

If you're prepared for more complex manipulations, you can turn off unnecessary system services through ADB (Android Debug Bridge), which doesn't require superuser rights, but requires a computer, and is suitable for power users.

What you need:

• A computer with Windows/Linux.
• Installed Xiaomi drivers (download MIUI ROM Flashing Tool).
• USB Debugging enabled (Settings → About Phone → MIUI Version → 7 taps → For developers → USB debugging).

Commands for cleaning RAM:

adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS


adb shell pm trim-caches 1000000000 # Clears the cache of all applications




adb shell am kill-all #Closing all processes

To disable unnecessary services (e.g. MiuiDaemon, which consumes up to 150MB of RAM):

adb shell pm disable-user --user 0 com.miui.daemon

⚠️ Warning: Don't turn off services at random:

• Stop notifications from Google Play Services.
• Deactivated geolocation.
• Loss of communication with Xiaomi servers (no updates will be received).
