How to effectively clean RAM on Xiaomi Redmi smartphones

Modern smartphones Xiaomi Redmi line have impressive performance, but even powerful hardware over time begins to experience a shortage of resources. RAM (RAM) is a critical component that ensures multitasking and smooth operation of the interface MIUI or HyperOS. When free RAM volume ends, the system begins to force the background applications to close, and animations become twitchy.

Users often notice that after months of active use, the device starts to work slower than on the first day after purchase. It is a natural process of cache accumulation and background processes that do not always end correctly. Proper memory cleaning allows you to return the gadget to its former sharpness without having to do a full reset to factory settings or buy a new model.

In this guide, we will not only look at the standard methods available to every owner, but also advanced optimization techniques. You will learn how to manage processes correctly, what Android functions should be turned off to save resources and why conventional “accelerators” are not always effective. Understanding the principles of virtual memory will help you keep your smartphone in perfect technical condition.

Built-in MIUI and HyperOS optimization tools

Xiaomi shells have their own set of maintenance utilities that are in the back of the settings. The standard approach for most users is to close applications with a swipe, but this does not free RAM completely, since many services restart instantly.

Run the Safety program on the home screen and click on the Cleanup button. The system will analyze the occupied volume and suggest removing temporary files. However, to work with RAM, you need to go to the Accelerate section. This shows the list of running processes, and the cleanup button really tries to complete the tasks that consume the most resources.

• 🚀 Click the Clear button to force background tasks to be completed and megabytes freed.
• ⚙️ In the accelerator settings, you can add important applications to the exception list so that they do not unload.
• 📊 Auto Acceleration automatically cleans the memory when the occupancy reaches a certain threshold.

⚠️ Warning: Aggressive cleaning through a standard accelerator can cause important notifications from messengers to arrive with a delay, as the process will be completely destroyed by the system.

It's worth noting that constant manual cleaning isn't always helpful. Android is designed to keep frequently used apps in memory for quick start-up. If you constantly reset RAM, the processor has to reload data from the disk, which consumes battery power and creates extra load.

Managing Autoboot and Background Processes

One of the main reasons for memory overflow is the excessive number of applications running with the system. Unlike pure Android, the MIUI shell allows you to control this parameter in detail through special developer settings or built-in restrictions. Disabling excessive autoboot is the most effective way to reduce the base load on the processor and memory immediately after the device is turned on.

To manage this setting, you need to activate the developer menu if it is hidden. Go to Settings → About your phone and quickly click 7 times on the MIUI version. Once the activation message appears, the Developer section will appear in the advanced settings. You need to find the AutoStart item or use a separate Permissions application in the tool folder.

In addition to auto-run, check the battery optimization settings for each application. The system can limit the background activity of programs, which indirectly affects the amount of RAM they occupy. Go to Settings → Applications → All applications, select an unnecessary program and set a limit to background activity. This will prevent it from working in hidden mode.

Developer settings for advanced cleaning

For users who want to gain maximum control over the system, the Developer Menu provides access to hidden memory management functions, where you can forcely limit the number of background processes, which dramatically changes the behavior of the operating system, but these settings require caution, since an incorrect configuration can lead to unstable interface operation.

Find the Apps section in the developer menu and select the "Background Process Limit" option, which is the default limit, but you can change it to "No More than 2 Processes" or "No Background Processes." This will cause the Android aggressively system to unload anything that is not in the foreground, freeing up a maximum of RAM for the current occupation.

• 🛑 The “Do Not Run Services” option allows you to completely stop Google services or systems, but this can disrupt the operation of geolocation.
• 🔄 The “Do Not Save Actions” function in the “Applications” section prevents the state of activity from being saved, saving memory.
• 📉 Turning off window animations also reduces the load on the GPU and visually speeds up work.

⚠️ Note: Setting a hard limit on background processes (e.g., 0 or 1) can cause the music in the player to stop when switching to another screen and the navigator to reset the route.

Another important setting is to disable layer caching. In the "Hardware Rendering Acceleration" section, you can find the option "Disable Hardware Acceleration", but most often the item related to the cache is interested in: Reducing the size of the cache or completely cleaning it through the cache. ADB-Teams can give temporary performance gains on older Redmi models.

Memory Extension (Memory Extension)

Modern Xiaomi models with MIUI 12.5 and later, and HyperOS, have a virtual memory extension feature that allows you to reserve a portion of internal storage (ROM) and use it as additional RAM, which is based on the zRAM standard and helps keep more applications open.

To activate this feature, go to Settings → Advanced Settings → Expanded Memory. Here you will see a slider that allows you to add 2 to 7 GB (depending on the model) of virtual RAM. Once turned on, the phone will suggest a reboot. It is important to understand that the internal drive speed is lower than the speed of real RAM, so the performance gains are not noticeable in all scenarios.

The use of memory extensions has its own features and limitations. If you have a fast UFS 3.1 storage installed, the effect will be positive. On low-end models with slow eMMC memory, turning on this feature may, on the contrary, reduce the overall responsiveness of the system due to the low read/write speed when actively swapping data.

• ➕ Enable the extension if you have a lot of heavy apps and 4-6 GB of physical memory.
• ➖ Turn off the feature if you notice micro-fries interface or problems with recording video.
• 💾 The function takes up space on the internal drive, reducing the available space for photos and videos.

💡

If you are actively using the camera to shoot 4K video, temporarily disable the memory extension, which will free up the recording buffer and prevent possible file saving errors due to lack of resources.

Use of modes of operation and Game Turbo

For gamers and users who want to maximize performance at a given moment, Xiaomi has developed Game Turbo Mode, which not only clears the memory before starting a game, but also redistributes the CPU priorities, giving all the resources to the active application, which is the most effective way to ensure stable FPS in heavy games.

Add the app to the list of games through the app Security → Game Turbo. When you start the game from the side, the toolbar will appear. Clicking on the icon Clean or Bust will instantly unload all unnecessary processes. In addition, in the Game Turbo settings, you can activate the Performance mode, which ignores some of the system’s limitations for the sake of speed.

There's also a standard "Second Space" or "Guest Mode" mode, which sometimes helps isolate processes. Running a clean environment without heavy apps installed allows you to check if a particular software is causing a memory leak. If in guest mode the phone is fast, the problem lies in one of your main applications.

⚠️ Warning: Continuous use of high performance mode or Game Turbo in the background (if such an option is active globally) leads to rapid heating of the case and battery degradation.

Radical methods: Resetting and flashing

If the software cleaning methods fail and the Redmi smartphone continues to slow down even after the reboot, there may be critical errors or damage to file tables in the system. In this case, the (most effective) method is a complete reset to factory settings, which completely clears the RAM and internal memory of user debris.

Before performing a reset, be sure to back up your data via Settings → About Phone → Backup Recovery or through the Mi Cloud. The process takes time: go to Settings → Advanced Settings → Reset and Reset → Reset. Once cleaned, the phone will be like new, with standard free storage.

For advanced users, there is a method of flashing through Fastboot with Wipe All Data clean, which ensures that even system files that may have been damaged in the air update process are deleted. Clean installation of global or Chinese firmware often works wonders with the performance of older devices.

💡

Full reset is the only way to ensure that hidden system debris is removed that cannot be cleaned with standard cache cleaning tools.

After reset, take your time to install all the apps at once. Install only the necessary programs and observe the behavior of the system for a couple of days. This will help identify the “culprit” of slowdown if the problem was caused by a particular application you previously installed.
