Owners of the popular Xiaomi Redmi Note 7 smartphone often face a situation when the device starts to work slower, applications open longer than usual, and the system periodically hangs. The main reason for this behavior is a lack of free RAM, which is filled with background processes and temporary files. Timely cleaning of RAM allows you to instantly return the gadget to its former speed and responsive interface.
The modern MIUI shell has many built-in optimization tools, but not all users know how to use them properly. It is important to understand the difference between photo storage and RAM, because the methods of cleaning them are radically different. In this article, we will discuss in detail all ways to free up resources, from regular funds to advanced settings for power users.
Analysis of current memory status
Before you start to take action, you need to understand what your RAM is doing. Unlike permanent storage, RAM (memory-only) only works with data when you use applications. The more programs you run at the same time, the less resources you have left to run the system.
You can check your current download through the standard developer menu or third-party monitoring tools. Pay attention to processes that consume resources even in the background. Often these are social networks or messengers that constantly update content.
If less than 15-20% of the total memory is left, the system begins to force the closure of active tabs and applications. This is the Android security mechanism, which prevents a complete system failure, but it negatively affects the user experience.
Use of the built-in MIUI cleaner
The easiest and safest way to free up resources is to use the standard “Security” application, which is preinstalled on every Xiaomi Redmi Note 7. This tool is designed specifically for working with the MIUI shell and correctly closes processes without violating the stability of the system.
To start the procedure, go to the menu and select the appropriate application. Click on the large green Clean button. The system will automatically analyze the processes running and suggest that the processes that consume the most resources be closed.
⚠️ Warning: Don’t use third-party accelerators from the Play Market if you have enough functionality, which often put extra strain on the processor, constantly running and stopping services to demonstrate activity.
Once you have finished scanning, you will see a list of applications that you can close, and it is recommended to run this procedure periodically, especially before starting heavy games or resource-intensive tasks, but it is worth remembering that completely cleaning up all background processes can lead to longer launch of frequently used programs the next time you access them.
💡
For quick cleaning, run the game in Game Turbo mode - the system itself optimizes the allocation of memory for the gameplay.
Manual control of running applications
App control allows the user to decide for themselves which processes should run in the background and which can be completed, especially for the Redmi Note 7, which, despite good optimization, has limitations on the amount of RAM available in the basic versions.
To access the list of active applications, you need to open the menu of recent tasks, usually done by swiping from the bottom up with a delay or pressing the Menu button at the bottom of the screen.
- 📱 Press and hold your finger on the app card to see additional control options.
- 🔒 Use the “Clock” function for important applications so that the system does not close them when automatically cleaning them.
- 🗑️ Click the Clear button (cross or broom) at the bottom of the screen to close all unlocked processes.
It's important to distinguish between apps that you use all the time and apps that hang in the background for no reason, like a navigator or music player, if you're planning to use them soon, but heavy games or photo editors can be safely closed after use.
☑️ Background process verification
Cleaning cache and temporary files
Cached data is one of the main reasons for space shortages and smartphone slowdowns. Cache is temporary files that apps save to load content faster when re-accessed. Over time, this data can take up gigabytes of space and load the system.
Cleaning can be done both through the menu of each individual application and globally through the system settings. For selective cleaning, go to Settings → Applications → Application Management. Select the desired program (for example, a browser or a social network) and click Memory.
In the menu that opens, you'll see two buttons: Clear cache and Clear everything. The first one deletes only temporary files without affecting your personal data, logins and passwords. The second button completely resets the app to factory settings, removing all local information.
| Type of data | What's removed | Impact on the account | Recommendation |
|---|---|---|---|
| Cash. | Temporary files, thumbnails | No. | It is safe to remove regularly |
| Application data | Settings, logins, saves | Exit from account | Only when the software is in trouble. |
| Cookies | Tracking, authorization on websites | Entry to the sites is required | Periodic cleaning |
| Media cash | Viewed photos / videos in chat rooms | No. | Clean through messenger |
Pay particular attention to messengers like Telegram or WhatsApp, which have built-in memory management tools that are often more effective than the system, and you can find the Memory Use section in chat settings and clear the media cache, freeing up a significant amount of resources.
Disabling Visual Effects and Animation
MIUI’s graphics shell is famous for its beautiful animations, but they also consume RAM and CPU resources. Disabling or accelerating these effects can dramatically improve the performance of the Redmi Note 7, especially on older versions of firmware.
To access these settings, activate the developer mode. Go to Settings → About Phone and quickly click on the MIUI version seven times. After the message “You became a developer” appears, go back to the main settings menu and find the “Advanced Settings” → “For Developers”.
Inside the menu, find the section that's responsible for drawing, and zoom in on the animation of the windows, transitions, and animator duration. Set a value of "No animation" or "0.5x" instantly speeds up the interface response, and it doesn't free up memory directly, but it reduces the load on the system when you switch between tasks.

Removing Bloatware (Bloatware)
Xiaomi smartphones often come with a pre-installed set of apps that the user may never use.These programs, known as bloatware, can run in the background, consuming precious RAM.
Not all system applications can be removed in the standard way. For some, only the "Disable" feature is available, which hides the icon and prevents the process from starting, enough to stop the application from taking up space in RAM. Go to application management and carefully study the list.
If standard methods to remove unnecessary software fail, you can use tools for PCs such as ADB (Android Debug Bridge), which requires connecting the phone to the computer and typing commands, but allows you to remove almost any system components without obtaining superuser rights.
adb shell pm uninstall -k --user 0 name.packet.applicationsBe extremely careful when removing system packages through ADB. Removing critical components can result in a cyclical reboot or loss of functionality of the smartphone. Always check the purpose of the package online before removing it.
⚠️ Note: Before removing system components through ADB Make sure to make a complete backup of the data. Recovering remote system applications can be a difficult task for a beginner.
Optimization of the browser
Web browsers are among the most voracious consumers of RAM. Each open tab, especially with "heavy" media content or scripts, takes up a separate process in RAM. On devices with limited memory, this quickly leads to brakes.
It is recommended to set a limit on the number of tabs open or close them regularly. Most browsers (Chrome, Mi Browser) have a “Close all tabs” function or the ability to group tabs to save resources, and it is also worth turning off page preloads if this option is active.
Using lightweight browser versions like Chrome Go or Opera Mini can be a great solution for the Redmi Note 7.These versions are optimized for running on devices with modest specs and consume significantly less RAM when surfing.
💡
Regularly cleaning browser tabs is the easiest way to instantly free up to 30-40% of RAM without using third-party utilities.
Energy saving as a way to optimize
Power saving is not only a way to extend battery life, but also an effective way to clean up memory, and when activated, MIUI forces applications to limit background activity and reduces processor frequency.
This causes many background processes to simply not start or be terminated immediately by the system, and for tasks that do not require high performance (book reading, listening to music, simple calls), this mode is ideal for maintaining stable operation.
There is also a Super-Energy Saving mode that turns a smartphone into a basic phone with a limited set of features, with a minimum number of applications available in this state, which guarantees maximum interface speed even with a heavily loaded system.
