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

Why Redmi 7 is slowing down and how it relates to RAM

Your Xiaomi Redmi 7 is slow to open apps, hang around when switching between tasks, or shut down background processes spontaneously? 90% of the time, it's because of overloaded RAM. Despite the fact that the model was produced with 2 or 3 GB of RAM, the MIUI system aggressively reserves up to 40% of memory for background services even at minimal load, a feature of firmware, not a defect in the device.

The performance of the Redmi 7 based on the Snapdragon 632 is critically dependent on free RAM. When it is less than 300 MB, the phone begins to kill active applications to free up resources. Users often confuse this with memory leaks or viruses, but the real reason lies in the architecture of MIUI and the limited hardware capabilities of a budget smartphone. Next, we will discuss how to diagnose the problem and return the device to speed without radical measures like resetting to factory settings.

How to check the current RAM load on Redmi 7

Before you clean up your memory, you need to understand how busy it is. MIUI has built-in monitoring tools, but they're hidden in the back of the menu.

1. Open the Settings. → The phone.
2. Tap 5 times on the MIUI version until the notification “You became a developer” appears.
3. Go back to the main settings menu and find a new section for developers.
4. Scroll to the Debugging block and select Memory Information.

Here you will see a real-time usage graph of RAM, including:

• 📊 Total memory (2 or 3 GB depending on the modification of the Redmi 7)
• 🔄 Used by applications (active processes)
• 🖥️ System services (background tasks) MIUI)
• 🗑️ Free (critical - if less than 200 MB, cleaning is required)

An alternative method is to use the Quick Settings widget, swipe down from top to top to open the notification bar, and find the RAM icon (if not, add it through panel editing), and tap it to show the current boot and suggest cleaning.

Manual cleaning of RAM: 3 ways without third-party applications

If there's less than 300MB of free memory, it's time to free it up, starting with the built-in MIUI methods, which don't require any additional software.

1. Quick cleaning through the notification panel

The easiest way to do this is to work even on a locked screen:

1. Swipe your finger from top to bottom to open Quick Settings.
2. Find the RAM icon (usually located next to Mobile Data or Wi-Fi).
3. Slip on it – the system will show a list of active applications.
4. Click Clean (or Clean All) to close the background processes.

This method frees up to 500-700 MB of memory, but has the drawback: after 10-15 minutes, MIUI will again load some services into the background.

2.Deep cleaning through "Safety"

MIUI firmware has a hidden tool for system optimization:

1. Open the Security app (the shield icon).
2. Go to Optimization (or Acceleration in older versions).
3. Click Memory Cleanup – the system will scan the background processes.
4. Choose Deep Cleanup and confirm the action.

This method removes not only active applications, but also the cache of system services, which gives a gain of free memory for 20-30% longer than a quick cleaning, but after the procedure, some functions (such as push notifications) can recover more slowly.

Close all important applications (save data)

Connect your phone to charge (the process consumes up to 15% of the battery)

Turn off the mobile internet (to avoid interruption)

Remember passwords from accounts (you may need to re-enter them)-->

3. Forced suspension of unnecessary services

Some MIUI system processes (e.g., com.miui.analytics or com.xiaomi.midrop) consume RAM even when you're not using them.

1. Go to Settings → Applications → Application Management.
2. Slip on the three points in the upper right corner and select Show System Processes.
3. Find apps with names miui.analytics, miui.daemon, miui.bugreport.
4. Open each and click Stop (not to be confused with Disconnect!).

⚠️ Note: Do not stop processes with the names android. or media. - this can lead to a system failure. Also avoid com.android.phone (responsible for cellular communication) and com.android.systemui (interface). MIUI).

Automatic RAM Cleaning: Configuring MIUI for Continuous Optimization

Manual methods give a temporary effect, but after a few hours the memory is clogged again. To avoid this, set up automatic optimization:

1. Enable the function "Memory Cleanup when blocked"

This option closes the background apps every time you lock the screen:

1. Open Settings → Battery and Performance.
2. Select Battery Management.
3. Activate the Memory Cleanup Switch when you lock the screen.

Once activated, the system will automatically release up to 300-500 MB of RAM when the screen is turned off.

2.Setting priorities for applications

You can manually specify MIUI, What applications should not be closed during cleaning:

1. Press the icon of the desired application on the main screen.
2. Select Application Information.
3. Slip the battery. → No restrictions.
4. Enable the option to Disable Memory Cleanup.

This method is useful for instant messengers, music players or navigation applications (such as Yandex.Maps or Google Maps) that need to work in the background.

Third-party applications for cleaning RAM: is it worth using

There are hundreds of apps on Google Play that promise to "magic" memory cleanup with one tap, but most of them are either useless or harmful.

• 🧹 CCleaner – clears the cache, but does not affect the background processes MIUI. Useful once a week to remove garbage, but not to release RAM.
• ⚡ Greenify really freezes unnecessary apps, but requires root rights to work properly.
• 🔥 Clean Master – aggressively closes processes, but often deletes important system files, leading to lags.
• 🛡️ SD Maid – useful for cleaning residual files after deleting apps, but does not optimize RAM.

⚠️ Attention: RAM cleaning applications themselves consume up to 100-200MB of memory in the background. For example, Clean Master keeps a constant com.cleanmaster.mguard process in RAM, which eats up to 15% of resources.

If you still want to use third-party software, choose Greenify (for power users) or Simple System Monitor (for real-time RAM load monitoring), but remember: no application will clean up memory better than the built-in MIUI tools.

💡

To reduce the load on RAM, disable the animation interface. To do this, activate Developer Mode (as described above) and in the developer settings set the window animation scale, transition animation scale and animation duration on No Animation. This will save up to 100 MB of RAM.

Cleaning RAM through ADB: for advanced users

If standard methods don't work, you can use the Android debugging bridge (ADB), which requires connecting your phone to your computer, but gives you complete control over the processes.

Preparation for working with ADB

You'll need:

• 🖥️ Computer with Windows, macOS or Linux
• 🔌 Cable USB Type-C (original or qualitative analogue)
• 📥 Google Platform Tools (download and unpack)
• 📱 Included Developer Mode and Debugging by USB Redmi 7

Commands for RAM cleaning

Connect your phone to your PC and execute the following commands at the Terminal (Command Prompt or Terminal):

1. Connection Check: Adb devices (Serial number of your Redmi 7 should appear)
2. Review of current processes (to see what can be closed): adb shell dumpsys meminfo
3. The Forced Release of Memory: Adb Shell Am Broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS This command simulates clicking the “Clear Everything” button in the notification bar.
4. Stopping a particular process (e.g. com.miui.analytics): adb shell am force-stop com.miui.analytics

ADB-The method is most effective, but it requires caution, and the wrong command can lead to system failure or data loss.

What to do if nothing helps: radical measures

If after all the manipulations Redmi 7 continues to slow down, and free memory is less than 200 MB, it’s time for serious steps:

• 🔄 Factory reset - deletes all data but returns the phone to a "clean" state. → Additionally. → Backup and reset.
• 📉 Retrace to the old version MIUI — If the lags started after the update, try to return the firmware to 1-2 versions back. 4PDA model-themed.
• 🔧 Thermopaste replacement – overheating of the Snapdragon 632 processor leads to trottling (decreased performance).°C, maybe it's time to serve him physically.
• 🆕 Increasing RAM through a swap file is an advanced method that requires root rights. It allows you to use part of the internal memory as virtual RAM.

⚠️ Note: Redmi 7 with 2GB of RAM is not recommended to install custom firmware like LineageOS or Pixel Experience. These builds are often optimized for devices with 4GB of RAM.+ GB of memory and can work slower than native MIUI.

💡

If the problem persists after the factory reset, it is likely that the memory chip is physically worn out, in which case only replacing the motherboard or buying a new phone will help.
