Smartphone Redmi 9A from Xiaomi deservedly considered one of the most affordable devices on the market, but its budget filling often causes slow system performance. Users often face a lack of RAM, which leads to constant reboots of applications and interface lags. There is a natural desire to physically or programmatically expand available resources for more comfortable use of the gadget.
Unfortunately, the physical replacement of memory chips in modern smartphones is impossible without professional soldering equipment and deep knowledge of microelectronics. However, there are software methods that allow you to redistribute system resources and use the free space in internal storage for the needs of RAM. In this article, we will discuss in detail what real steps can be taken by the owner of the Redmi 9A to optimize performance.
You can't count on a miracle that turns a budget budget into a flagship, but a competent setup can significantly extend the life of the device. We'll look at the regular features of the MIUI shell, the capabilities of the developer and third-party software that can help solve the problem of lack of resources.
Why is there a lack of RAM on the Redmi 9A?
The main reason for the lack of resources is the architecture of the device itself. The Redmi 9A model initially features a modest amount of RAM, which in the basic versions is only 2 or 3 gigabytes. For modern versions of the Android operating system and heavy shells like MIUI, this volume is critically small, since the system itself consumes a significant part of the available space.
Compounding the situation is the ever-increasing demand for mobile apps: Social networks, messengers and browsers are becoming increasingly “heavy” with each update, requiring more RAM for background work. Even simply running a map or watching high-resolution video can lead to automatic closure of background tasks, since the system has nowhere to place new data.
⚠️ Warning: Attempts to install unofficial modified firmware to increase memory can lead to complete loss of warranty and unstable operation of the device.
It’s also worth considering the features of MIUI shell optimization, which is known for its aggressive memory management, often unloading applications from memory faster than necessary to free up resources for the current task.
Check the current RAM volume and occupied space
Before you start any optimization action, you need to know exactly how much resources you are working with. Xiaomi’s standard interface does not always show the full picture of real-time download, so you should use built-in diagnostic tools to understand how critical the lack of RAM in your particular case is.
For more detailed information, you can use an engineering menu or third-party utilities that display the system more transparently, and it's important to distinguish between shared memory and free, available to run applications right now.
Follow the following steps to verify status:
- 📱 Open the Settings menu and find the About Phone item.
- 📊 Click several times in a row on the line Version MIUI, to activate additional options (if required).
- 🔍 Go to Advanced Settings and select Developers.
- 📈 Find Memory or Launch Security Application -> Acceleration.
The developer section often provides more detailed statistics showing which processes consume the most RAM, and analyzing this information will help identify “gluttonous” applications that can be removed or restricted.
Hidden codes for diagnosis
Use of the Virtual RAM (Memory Extension) function
One of the most effective regular ways to solve this problem is to use technology that allows you to use some of the internal flash memory for the needs of RAM. In newer versions of the MIUI shell, this feature is often called Memory Extension or Memory Extension, which creates a virtual partition that the system perceives as additional RAM.
It’s worth noting that the speed of internal memory (UFS or eMMC) is well below the speed of real RAM, so the performance gains will be noticeable in multitasking (holding apps in the background), but not in the speed of opening heavy games. However, for the Redmi 9A, this can be a salvation from constant interface reboots.
Activation of this function usually occurs through the following steps:
- 🚀 Go to Settings -> Additionally -> Expansion of memory.
- 💾 Select the available amount to allocate (usually available from 1 to 3 GB).
- 🔄 Confirm the action and wait for the device to restart.
☑️ Check before expansion
If you don’t have one on your menu, it means that your firmware version or a particular Redmi 9A model didn’t have the option added by the manufacturer software, so you can try upgrading to the latest available version via the About Phone menu.
⚠️ Note: Using virtual memory increases the number of write cycles per internal drive, which could theoretically shorten its lifespan, although this is not a critical factor for modern chips.
Set up developer parameters to optimize
Deep in the Android system settings, there are tools that allow you to manually control the behavior of the system with memory. The Developer section contains options that can forcibly limit the number of background processes, freeing up precious megabytes of RAM for an active application.
But you have to be very careful about these settings, because if you change the limits, you can stop sending notifications to messengers and stop the music when you roll up the app, and the goal is to find a balance between performance and functionality.
Let’s look at the key settings available in this section:
| Parameter | Recommended value | The effect |
|---|---|---|
| Limit of background processes | No more than 2-3. | The system will store fewer applications. |
| Window animation | 0.5x or Retraction. | Visual acceleration of the interface, less load on the GPU |
| Background constraint | Standard constraint | Balance between energy and memory |
To access these settings, you need to go to Settings -> About Phone and quickly click on the MIUI Version 7 times. After the message "You became a developer" will open a new menu in the Additional section.
💡
Reducing animation to 0.5x does not add physical memory, but it does make the system subjectively faster, as less time is spent on rendering transitions.
Third-party applications for memory management
Google Play has a lot of tools that promise miraculous memory enhancement, which work by aggressively ending background processes and clearing cache, and popular examples include SWAP No Root or various Game Boosters.
Applications like SWAP attempt to create a swap file on internal memory, similar to Windows. However, on Android, with its file system and access rights, this works less efficiently and often requires root rights, which can block banking applications from working on Redmi 9A.
The main types of applications for optimization:
- 🧹 Cache cleaners: Delete temporary files, freeing up space, but do not add OZ
