Effective cleaning of RAM on Xiaomi Redmi Note 7

Xiaomi’s Redmi Note 7 lineup has long been a bestseller for its excellent value for money. However, over time, even powerful hardware can run into a shortage of resources, especially if you’re actively using heavy applications and multitasking. RAM is a critical component that directly affects the speed of the interface and games. When it’s full, the device starts to hang over and the background processes are forced to close.

MIUI owners often wonder how to free up resources without harming the system. There are many myths that memory needs to be cleaned all the time, but the reality is that good process management is more important than blind cleaning. In this article, we will look at proven optimization methods that really work on the Redmi Note 7 and will help extend the life of your gadget.

Before you go to radical measures like resetting, it’s worth trying software optimization methods: they’re secure, they don’t require root rights, and they only take a few minutes of your time. Understanding how Android manages memory will help you avoid mistakes and keep your smartphone stable in the long run.

Analysis of the current memory situation

The first step is diagnostics, so you don't have to guess which applications are eating up all the resources, you have to look at the facts, and the MIUI has built-in monitoring tools that show you how the system is actually loading at a given time, and that allows you to see if the memory deficit is permanent or if it only happens when certain programs are running.

Notice how your smartphone behaves after you turn it on. If you have less than 30-40% of your RAM right after you boot, you have too many processes in your autoload. This is typical of Xiaomi devices with a lot of services pre-installed. You can use an engineering menu or third-party utilities to accurately evaluate, but often standard tools are enough.

It is important to distinguish between cached data and active processes. Android is designed to keep frequently used applications in memory for quick start. Forced cache cleaning can even slow down as the system will have to re-load data from the disk. However, “heavy” applications that hang in the background and are not used, you need to delete from memory manually.

⚠️ Warning: Don't use the Play Market accelerators with dubious reputations. They often consume more resources than they free up and display intrusive advertising.

Standard cleaning tools in MIUI

The MIUI shell on the Redmi Note 7 has powerful built-in functionality to maintain the system, and the main tool here is the Security app, which is pre-installed on all devices of the brand, and it can not only scan for viruses, but also effectively manage RAM.

To clean up quickly, you just run a scan through the main menu of the application, and the system automatically closes the background processes that are not system or critical, and this is the easiest way to quickly make room before launching a demanding game or heavy application.

• 📱 Open the Security app on the desktop.
• 🧹 Press the Clean or Accelerate button in the center of the screen.
• ⚙️ Wait for the analysis to be completed and press the clean button if the system suggests doing so.
• 🔄 For more in-depth settings, go to Settings inside the security application.

In the accelerator settings, you can set automatic cleaning when you reach a certain memory loading threshold. This is a useful feature, but it can be aggressive: if you like to keep multiple applications open at once, it is better to turn off auto-cleaning or set it to a higher threshold.

Manual control of running applications

Manual control allows you to pinpoint the applications that consume the most resources. On the Redmi Note 7, this can be done through the multitasking menu. The swipe up the application card completely closes it, freeing up occupied RAM.

But just closing apps isn't enough. You need to set limits for programs that you don't use very often, but that are constantly hanging in the background. You have a memory saving feature in your battery settings and MIUI applications, or a background activity restriction.

Go to Settings → Applications → Application Management. Select a voracious app and find Autostart. Turn it off for all programs except messengers and alarms. This will prevent them from starting immediately after the phone is turned on.

Also worth paying attention to is the app freeze (App Twin or embedded restrictions). MIUI You can freeze the app completely when the screen is off, and that drastically reduces memory consumption, but you won't get notifications until you open the app again.

Set-up of Developer Parameters

For advanced Redmi Note 7 users, there is a hidden section called "Developers" that contains subtle system settings that can significantly affect memory management, and to get there, you need to click 7 times on the build number in the About Phone section.

In the developer menu, find the item "Background Process Limit"; the default is "Standard Limit", but you can change it to "No More than 2" or "No More than 3 processes", which will severely limit the number of applications that can remain in memory after leaving them.

Another important setting is "Do Not Stay Activated." If you turn on this option, the system will destroy the activity of the application as soon as the user leaves it, which will free up RAM as much as possible, but can cause applications to boot again every time they open, which is not always convenient.

• 🔧 Go to Settings. → Advanced settings → For developers.
• 📉 Find the "Applications" section».
• 🚫 Select “Background Process Limit” and set a reasonable limit.
• ⚡ Optionally turn on “Do not remain active” for maximum performance.

⚠️ Attention: Changing the settings in the For Developers section can cause some applications to work in an unstable way.Be careful and change the settings one by one, checking the result.

Use of MIUI Developer Mode and Debugging

The latest versions of Xiaomi firmware have added additional optimization tools hidden in deep menus, such as Game Turbo, which not only improves game performance, but aggressively unloads background processes, freeing up maximum RAM for running a game.

Also worth considering is the use of ADB (Android Debug Bridge) to remove system debris that cannot be removed by standard methods, which requires a connection to a computer, but gives root-like rights without the need to unlock the bootloader.

adb shell pm list packages | grep "name packet"


adb shell pm disable-user --user 0 com.example.bloatware

With these commands, you can disable MIUI system applications that are always in memory, but you only need to do this if you know exactly what the package is for. Disabling critical system components can lead to a cyclical reboot of the Redmi Note 7.

💡

Before removing system applications via ADB, make sure to make a full backup of the data. Recovering a remote system package without resetting can be very difficult.

Cardinal measures: Resetting and flashing

If the software methods don't work and the smartphone keeps slowing down, maybe the problem is the accumulated system debris or conflicts after the updates, in this case, a complete factory reset, which will return RAM to the "out of the box" state.

Before reset, be sure to save all important data to the Mi Cloud cloud service or computer.The cleaning process will completely destroy user files, settings and installed applications.

After reset, take your time to install all the apps at once. Install them one at a time and monitor memory consumption. This will help identify the brake culprit if there was a problem in a particular application. Also consider installing custom firmware (like LineageOS or Pixel Experience), which often work lighter and faster than stock MIUI on older devices.

💡

Factory Reset is the most radical, but often the only way to completely clean up RAM from software errors and accumulated debris that is not cleaned up by other methods.
