How to clean RAM on Android Xiaomi Redmi 7

Redmi smartphones are famous for their availability, but models of the past, such as the Redmi 7, often face a shortage of RAM, which leads to constant reboots of applications, long interface loads and noticeable friezes when switching between tasks. Owners of devices with 2 or 3 GB of RAM are especially acutely feeling the lack of resources when the system begins to aggressively unload processes from the background.

RAM (Random Access Memory) cleaning is not just a way to free up megabytes, but a necessary procedure for the stability of MIUI. Unlike the permanent memory where your photos and applications are stored, RAM works with data that the processor is processing right now. The less junk in this fast buffer, the more responsive the Xiaomi Redmi 7 works.

In this guide, we will not only break down standard cleaning methods, but also the hidden developer settings that allow you to actually increase the amount of memory available, learn how to manage background processes that consume resources invisibly, and understand which system services can be safely turned off to speed up work.

Analysis of the current state of memory and search for "eaters"

Before you start to take action, you need to understand what your RAM is doing. The standard MIUI interface doesn't always show the full picture, so it's important to look at the engineering menu or use built-in monitoring tools. It often turns out that the lion's share of resources is not the applications you run, but system services or heavy social networks.

To start, use a standard dispatcher. Swipe down to open the notification curtain and tap the broom icon or go to the Security app. This shows the total load percentage, but the detail is often lacking. More in-depth analysis requires the developer mode to be enabled.

To activate hidden features, go to Settings → About Phone and quickly click on the MIUI version seven times. Once the notification “You are a developer” appears, go back to the main settings menu and select “Additional Settings → For Developers.”

⚠️ Attention: The developer menu contains critical system settings, changing the settings associated with window scaling or debugging. USB, Without understanding their purpose, it can lead to incorrect display of the interface on Redmi 7.

In the "Memory Statistics" or "Memory Use" section, you'll see a list of processes sorted by consumption. Notice the applications that you haven't used in recent hours, but they're still hanging in the background, and they're the main candidates for forced shutdown.

Standard cleaning methods through MIUI interface

The easiest and safest way to free up resources is to use a regular optimizer, which is integrated deep into the MIUI shell and can close processes more efficiently than a standard task manager of pure Android. However, just clicking the "Clean" button is not enough.

You should set up automatic cleaning. Go to the Security app, click on the three dots in the top right corner and select Settings. In the Memory Cleanup section, activate Auto Cleanup, which will allow the system to unload heavy applications on its own when free RAM becomes critically scarce.

• 🧹 Click on the Memory widget on your desktop for quick cleaning.
• ⚙️ Set up the exclusion of important apps from the White List menu so they don’t close.
• 🔄 Use the “Close All” button in the menu of running apps, holding your finger for mass closing.

It's important to understand that MIUI has a peculiarity: once cleaned, memory fills up quickly again. It's normal for a system to keep frequently used applications ready to run. If you see 80-90% of memory filled up, it's not always bad as long as the interface is running smoothly.

For owners of Redmi 7 with 2 GB of memory, it is recommended to set an aggressive cleaning mode. In the battery settings, you can limit background activity for applications that do not require constant connection, such as games or office suites, this will significantly extend battery life and reduce the load on the processor.

To quickly clean running applications on Redmi 7, you can use double pressing the Menu button (square), if the corresponding function is enabled in the settings of additional buttons.

Advanced settings for developers

For a deeper optimization of Xiaomi Redmi 7, you need to address hidden parameters in the menu for developers, here you can forcefully limit the number of background processes, which radically changes the behavior of the system on devices with low RAM.

Find the "Background Process Limit" option. The default is "Standard Limit." Change the value to "No More than 2 Processes" or "No More than 3 Processes." This will force the system to hard-download old applications from memory, making room for the current task. The interface will become noticeably more responsive, but notifications from closed applications may come with a delay.

Another important parameter is animation scaling. Go to the Windows animation, transition animation, and animation duration sections. Set a 0.5x value or turn off animation completely (without animation). Visually, this won't clear the memory, but it will reduce the load on the GPU and create a sense of faster device operation.

⚠️ Warning: A complete shutdown of animations can cause transitions between screens to become twitchy and sharp. On Redmi 7, the optimal value is 0.5x, It keeps the response smooth, but speeds up the response.

You should also pay attention to the "Do Not Activity" option, which, if you turn it on, will destroy the app as soon as the user switches to another screen, which is an extreme measure for cases where the phone is running at its limit, but it makes multitasking impossible.

Managing Autoboot and Background Services

One of the main problems with MIUI is the abundance of pre-installed and third-party applications that are prescribed for autoboot, which start with the inclusion of Redmi 7 and stealthily "eat" precious megabytes of RAM.

To manage your boot, go to Settings → Apps → Permissions → Autorun. Here you will see a list of programs that are allowed to run themselves. Leave only messengers (for notifications to come) and system services on. All games, stores and rarely used utilities safely turn off.

Also, many apps have their own settings in the background. Go to Settings → Battery and Performance (or just Battery). In the upper right corner, click on the gear to open the settings. Here you can customize the behavior of each application individually. For "heavy" programs, set "No Limits" only if you need instant notifications, otherwise select "Energy Saving" or "Background Activity Limiting".

Regularly checking this list helps keep the Redmi 7 in good shape. New installed apps often try to sign up for the boot without the user’s knowledge, so it’s worth a monthly review.

Using Developer Mode to Clean Cache

Although the application cache is stored in permanent memory, its excess can indirectly affect the speed of the system and the occupancy of data buffers. MIUI has a hidden feature that allows you to clear the cache of all applications directly through the developer menu.

In the Developer menu, scroll down to "Enable Cache Cleanup" (or similar name, depending on the version of MIUI) and activate this switch will add a new option to the smartphone switch-off menu (long press of the power button) - "Clean Cache".

This feature is especially useful before running “heavy” tasks, such as navigation or games. Freeing up space in permanent memory often gives the system more room to maneuver when working with RAM, since virtual memory (swap) also depends on free disk space.

Don't fanatically clean the cache every day. Do this only when you notice strange app behavior or when the storage is more than 90% full. For Redmi 7 with its limited internal storage capacity, this is a critical parameter.

Third-party solutions and radical measures

If Xiaomi's built-in tools fail, you can turn to third-party launchers or utilities, but on weak devices, installing heavy memory cleaners can do more harm than good, and they consume the resources they're trying to free up.

The best solution is to install lightweight launchers, such as Nova Launcher or Microsoft Launcher in their lighter versions, which consume significantly less RAM than the standard MIUI shell, which gives an increase in 100-200 MB of free memory, which is quite noticeable for the Redmi 7.

The radical measure is to completely reset the settings to factory settings. Before this procedure, make sure to back up all the important data. After resetting, do not restore all the applications immediately from the backup, but set only the minimum necessary, which will allow the system to work in "sterile" conditions.

⚠️ Note: When you reset, all data, including photos, contacts and files, will be deleted. Make sure you have an up-to-date copy on your computer or in Mi Cloud storage.

Custom ROMs such as LineageOS or Pixel Experience are devoid of the heavy MIUI shell and work much faster on older hardware, but they require skill and are unwarranted (if they are still relevant).

💡

Integrated approach: The combination of limiting background processes, disabling auto-start and using lightweight alternatives to heavy applications gives the maximum effect on the Redmi 7.
