How to Clean RAM on Xiaomi Redmi 7: The Complete Guide

Xiaomi Redmi 7, which is based on the Snapdragon 632 processor, is still popular due to its balance between price and performance. However, over time, owners begin to notice that the MIUI interface begins to slow down and applications load longer than usual, the main reason for this behavior lies in the overflow of RAM, which on this model is only 3 or 4 GB depending on the modification.

When free space in RAM runs out, the system is forced to constantly unload background processes, which leads to sharp spikes in delays and even a complete freeze of the device. Understanding how to properly manage Android resources allows you to significantly extend the comfortable use of the gadget without the need to immediately purchase a new flagship. In this material, we will analyze proven cleaning methods that will help return the Redmi 7 to its former froliction.

It’s important to note right away that a simple reboot doesn’t always solve the problem radically if hidden processes or heavy app caches have accumulated in the system. Competent optimization requires a comprehensive approach, from standard MIUI shell tools to deeper customizations through the developer menu. Let’s take a look at each step in detail so you can choose the most suitable option for your situation.

Use of the built-in Security application

The easiest and safest way to free up resources is to use the standard tools that are preinstalled in every Xiaomi smartphone.Security has a cleaning module that automatically scans the system for temporary files and inactive processes. Launch it from the home screen and click on the large green scan button.

Once the check is complete, the system will suggest removing the garbage. However, to work with RAM, you need to go to the Boost Speed section, which shows the current percentage of RAM downloads and a list of processes that can be completed. Pressing the cleaning button forcibly closes the background services, instantly freeing up space for the programs you run.

Consider that aggressive cleaning through this tool can lead to the re-run of important system services, which will again load the processor. Use this feature before running resource-intensive games or heavy applications, but do not make it a habit every five minutes. Android itself knows how to allocate resources efficiently, if it is not interfered with by constant interventions.

💡

For quick cleaning, you don’t need to open the app: on the home screen, just swipe down to open the widget bar and click the “Clean” button (broom icon).

Regular use of the standard accelerator helps maintain stability, especially on models with 3 GB of RAM. However, if the memory is refilled after cleaning in a matter of minutes, the problem may lie in a specific consumer application, which requires special attention and customization.

Manual control of running applications

Often users are unaware of how many programs are hidden in the background and consume precious megabytes. Unlike iOS, Android allows apps to stay active for quick launch, but on Redmi 7 with its limited RAM capacity, this can be critical. To see the full list, click the menu button (square or three bars depending on the type of navigation) or swipe from the bottom up with a delay.

In the list of running tasks that opens, you'll see cards of all active applications. At the top of the screen, there's usually a Clear* button that closes all programs at once. However, a more effective method is to selectively close heavy apps, such as social networks or marketplaces, that tend to inflate cache.

• 📱 Press and hold the app card to see additional control options.
• 🔒 Use the “Clock” function to lock important applications (such as messengers) into memory and protect them from being closed by a cleaner.
• 🗑️ Swipe the cards up to force the process you don’t need right now.

Special attention should be paid to geolocation and sync applications, as they often hang in the background and constantly update data. If you are not using the navigator right now, close Google Maps or Yandex.Maps to free up resources for other tasks. This is especially true if you notice that the phone is starting to warm.

Set up background activity restrictions

The MIUI shell provides advanced tools for controlling application behavior that do not require superuser rights. You can prevent specific programs from running automatically or running in the background, which will significantly reduce the load on RAM. Go to Settings → Applications → Application Management and select the desired software.

Inside the app card, find AutoStart and disable it for all programs except messengers. Also, under Battery and Performance (or simply Battery), you can select the mode of operation. For most applications, the optimal mode will be No Limits only if you need instant notifications, in other cases it is better to leave the standard mode or choose Charge Savings, which will limit background activity.

⚠️ Note: Do not disable auto-start for Google system services and applications from which you expect notifications (WhatsApp, Telegram, mail), otherwise messages may come with a delay or not at all.

Another effective method is to use Extended Cleaning in battery settings, where you can set up scenarios where the system will automatically close applications when the screen is locked or when the charge is low, which helps keep the Redmi 7 fast all day long without manual intervention.

Cleaning cache and deleting temporary files

Temporary file accumulation is one of the main reasons not only for the lack of storage space, but also for the indirect impact on system speed. When internal memory is filled to the fullest, Android starts to run slower, because it lacks space for swap files and temporary buffers, so cleaning the storage directly affects the availability of RAM.

Go to Settings → Memory and analyze what takes up the most space. Often it is the social network cache (VK, Telegram, Instagram) and videos viewed. In the settings of the application itself (for example, Telegram), you can find the Data Use and Storage item and clear the cache without deleting correspondence. This can free up several gigabytes, which is critical for stability.

Also, delete old download files. Go to Explorer → Downloads and delete APK installation files you already used. They are no longer needed, but continue to take up space and can sometimes run background update verification processes.

Cleaning garbage files regularly helps MIUI index content faster and less access to a slow internal drive, which eventually unloads the processor and RAM. Do this at least once a week for optimal performance.

Hiding animations and developer mode

For owners of Xiaomi Redmi 7 with a small amount of RAM, the great solution is to turn off or reduce visual effects. Animations of transitions, opening windows and zooming, although they make the interface beautiful, but consume GPU and memory resources. To access these settings, you need to activate the developer mode.

Go to Settings → About Phone and quickly click 7 times on MIUI Version. After you have the message “You became a developer”, go back to the main settings menu and open Additional settings → For developers. Find the section related to drawing or animation.

Windows animation scale: 0.5x or Disabled


Transition animation scale: 0.5x or Disabled




Duration of animation: 0.5x or Disabled

Changing the values to 0.5x will make the interface visually faster, and completely disabling (Disabled) will minimize the system. Also in this menu you can find the item "Limit of background processes." Set the value "No more than 2 processes" or "No more than 4 processes" so that the system tightly controls the number of programs running simultaneously.

After making the changes, it is recommended to restart the device, and you will immediately notice that the transitions between the screens have become instantaneous, and the applications have stopped “flying out” from memory when switching, this is one of the most effective ways to “rejuvenate” an old smartphone by software.

Third-party utilities and radical measures

If standard methods don't work, you can turn to third-party software, but you need to be careful. Many cleaners consume a lot of resources and show intrusive advertising that Redmi 7 can be worse than the problem itself.

Apps like Files by Google or SD Maid (in the paid version) are well-established, which can find deep debris and residual files from remote programs. But remember, no program works wonders: if physical memory is scarce, no accelerators will make the phone fly if ten heavy games are running.

⚠️ Warning: Avoid installing “antivirus” and “boosters” from unknown developers from advertising. They often contain miners or themselves are the source of load on the battery and processor, masquerading as useful tools.

The most radical measure is a complete reset to the factory settings (Hard Reset), before you save all the important data to the cloud or to the computer. A clean system without accumulated years of garbage, old settings and conflicts of programs is much faster and more stable.

💡

Full reset (Factory Reset) is a last resort, but it returns the smartphone state “out of the box”, freeing up the operational and permanent memory from digital junk.

In extreme cases, if the problem is caused by a particular firmware version, it is worth considering rolling back on a more stable version of MIUI or installing a custom lightweight build (for example, LineageOS), but this requires high technical skills and removes the warranty (if it is still valid).
