How to clean RAM on Xiaomi Redmi Note 7

Redmi smartphones have been leading the market for years, offering excellent value for money. However, even the time-tested Xiaomi Redmi Note 7 may start to run slower over time, especially if the amount of RAM is limited to the basic version. Have you noticed that applications are opening longer and background processes are often rebooted? This is a sure sign that the system resources are exhausted.

RAM is a critical component that stores data from running applications and system processes. When space runs out, the processor is forced to constantly unload old tasks to run new ones, which causes latency visible to the user.

In this article, we'll look at not only standard cleaning techniques, but also the hidden capabilities of MIUI, which are often ignored by owners, and you'll learn to distinguish between safe procedures and actions that can harm the stability of the gadget.

Analysis of the current RAM load

Before you start taking action, you need to assess the scale of the problem. Android provides built-in monitoring tools, but in the shell of MIUI they are often hidden or presented in a simplified form. It is important for the user to understand that free memory at 0% is not always a bad thing, as the system tries to keep frequently used applications in memory for quick start-up.

However, this changes if less than 500 MB are left free. In this case, background processes start to conflict, and the active application can “fly out” when switching. For accurate diagnosis, you can use the built-in engineering mode, which gives a more detailed picture than the standard widget.

⚠️ Warning: Don’t try to achieve 100% RAM cleanup. Android is designed to use the available resources as efficiently as possible, and total void will lead to unnecessary workload on the processor the next time you run applications.

To view detailed statistics, go to Settings → About Phone and click 7-10 times on Kernel Version (or MIUI Version depending on the firmware version) to activate the developer menu.

Here you'll see a graph of usage and a list of the hardest processes. Often, it turns out that the lion's share of resources is consumed not by games, but by Google's system services or aggressive messengers. Understanding what exactly "eats" memory is the first step to solving the problem.

Standard cleaning equipment in MIUI

The MIUI shell has a powerful built-in optimization toolkit that's in the Security app, and it's not just a shortcut, it's a full-fledged system module with deep access rights, and when you press the Cleanup button, the system forces the background processes to close and clear the cache.

However, using just one button may not be enough, and in the Security settings, you can set the level of aggressiveness of the cleanup, and you should also pay attention to the Memory Acceleration feature, which can be turned off by default in some regions.

• 📱 Open the Security app and select Cleanup section.
• ⚙️ Click on the gear in the upper right corner to access the cleaner settings.
• 🗑️ Activate Automatic Cleanup and select the interval.
• 🚀 Enable Memory Acceleration to Force Background Task Closing.

It's important to note that a standard cleaner can sometimes be too "polite" with system applications, and if you use heavy games or graphics editors, there may be a shortage of regular tools, which requires a deeper tweak to the settings.

💡

Add the Cleanup widget to the home screen for quick access, allowing you to free up one-tape memory before launching a demanding game or application.

Manual control of running applications

Automated systems don't always understand the context of use, sometimes you need to save the messenger in the background, but close the "heavy" browser or store, manual control allows you to point-free RAM resources.

In Redmi Note 7, navigation can be done in three buttons or gestures. For manual control, go to the menu of recent apps. Depending on the settings, this is done by swiping from the bottom up with a delay or pressing a square button.

To close applications, swipe the cards up. But there's a more efficient method: long-clicking on the app card opens a menu where you can choose to Secure or Clear memory. Securing useful applications (such as a bell or alarm clock) will protect them from unloading during general cleaning.

Special attention should be paid to browsers. Tabs left open in the background can take up hundreds of megabytes of memory each, and the habit of closing tabs or using incognito mode for temporary tasks will significantly unload the system.

Optimization through the Developer Menu

For advanced users, Xiaomi provides access to hidden settings that allow you to control the behavior of the system at a low level. The developer menu is a powerful tool, but requires caution.

To get into this menu, go to Settings → About Phone and quickly click 7 times on the MIUI Version. In the Advanced Settings menu that appears → For developers, find the Application section. There will be a Background Process Limit item.

⚠️ Attention: Setting too strict a limit (for example, "No background processes") can lead to incorrect notifications in messengers and loss of data in unsaved documents. 2-3 processes".

There's also a Do Not Save Action feature on this menu, which if you activate it, the system won't save the state of the application when you exit it, which will radically free up memory, but every time you open the program, it will start from scratch, like when you completely reboot it, and only use this option on devices with minimal RAM.

Disabling autoload and background activity

Many apps tend to start right after you turn on your phone, even if you're not using them right now, a phenomenon known as auto-run, and MIUI has a mechanism to control this behavior.

Go to Settings → Applications → Autorun. Here you will see a list of programs that start with the system. Ruthlessly turn off everything that is not critical (antivirus, alarm, system services). Messengers are better left on so as not to miss messages.

There is also background activity that can be limited for each application separately. Go to Settings → Applications → All applications, select the desired program and find Battery (or Energy Saving) option. Select No Limits mode only for important applications, and for the rest, set a Hard Limit or Battery Saving, which will prevent them from working in the background.

• 🛑 Turn off auto-run for gaming launchers and stores.
• 🔋 Use Power Saving Mode for Background Activity of Heavy Applications.
• 📵 Remove or freeze pre-installed apps (bloatware) that you do not use.

Regular auto-run audits help keep the system on track, and over time, the list can grow as new installed programs often prescribe themselves to start-up by default.

💡

Auto-start control is the most effective way to reduce memory consumption immediately after turning on the smartphone, without resorting to constant manual cleaning.

Radical measures and resetting settings

If none of these methods have worked, it may be the accumulated system debris or software errors that help reset the settings to the factory (Hard Reset).

This procedure will completely clear internal memory and RAM from user data and settings. Before performing the reset, be sure to back up all important data to the cloud server or computer, as they will be irretrievably deleted.

To do the reset, go to Settings → About Phone → Settings Reset → Clear all data. Once you reboot, you’ll get the device out of the box. Often this will bring back even older models like the Redmi Note 7 to the speed of their first days of use.

In rare cases, the problem may be associated with physical memory degradation or overheating of the processor, which causes the system to trottle and work with data more slowly. If the problem persists after the reset, it is worth considering diagnosing the hardware in the service center.
