Owners of the popular Xiaomi Redmi 8 Pro smartphone often face a lack of resources when running heavy applications or multitasking. The device's RAM is limited by factory parameters, and over time, accumulated cache and background processes begin to slow down the system. Many users are looking for ways to free up or even physically expand the available amount of RAM to return the gadget to its former aspiration.
There are several proven methods to optimize the use of RAM resources, some of which are secure and built into the MIUI shell, others require deeper intervention in system files, and it is important to understand the difference between real volume increases and software emulation, which can only create the appearance of improvements.
In this guide, we’ll take a look at all the options available, from standard developer settings to third-party utilities, and learn how to properly configure a swap file and whether it’s worth doing it on modern Snapdragon processors.
Analysis of current RAM load and diagnosis
Before making changes to the system, you need to evaluate the actual resource consumption. The MIUI shell has a built-in memory management mechanism that does not always display the full picture. For detailed analysis, you should use an engineering menu or third-party monitors.
Click the status bar in the Security app five times in a row to open the hidden menu, and you can see which processes take up the most space, and it often turns out that the background social media and messenger services consume up to 40 percent of the available volume.
⚠️ Warning: Do not force system processes to stop through the developer menu without understanding their functions, which can lead to unstable interface operation or cyclical device reboot.
For more accurate diagnosis, install the DevCheck app or use it. ADB-In the terminal, type adb shell dumpsys meminfo to get a detailed report on each application you run.
Use of the memory extension function in MIUI
Newer versions of MIUI firmware for a number of devices, including some Redmi 8 Pro modifications, have introduced a native memory extension feature that allows you to reserve some of your internal flash memory for the system, creating a virtual buffer.
To activate this option, go to Settings → Advanced Settings → Expanded Memory. If your firmware region supports this feature, you will see a volume slider. Usually 1 to 3 GB of additional space is available.
- 🚀 Includes fast switching between heavy applications without fully unloading them.
- 💾 Uses a high-speed portion of internal memory UFS data-buffering.
- ⚙️ Operates at the core level, which provides greater stability compared to third-party solutions.
It is worth noting that using this feature can slightly reduce the life of internal memory due to frequent overwriting of cells.
💡
If the Memory Extension option is not on the menu, try changing the region in the “Additional” settings to “India” or “Global”, then restart the device.
Set up developer parameters to optimize
The hidden developer menu contains tools that directly affect how the system manages RAM, and if you set these parameters correctly, you can free up a significant amount of RAM without installing additional software.
Turn on Developer Mode by quickly clicking seven times on the build number in the About Phone section. Then, in the Developer Menu, look for Apps. Here we are interested in the "Background Process Limit" item.
Set a value of “No More than 2 Processes” or “No Background Processes” if you want maximum performance in games. It is also recommended to turn off window animation by going down the Painting → Windows Animation Scale and selecting “0.5x” or “Disabled”.
☑️ Optimization through the Developer Menu
Creating a Swap File through Root Rights
For advanced users who are ready to take full control of the device, there is a method of creating a swap partition, which requires the presence of superuser rights (Root) and the installation of specialized software, such as SWAP No Root or KSWAP.
The method is to create a file on internal memory, which the system perceives as additional RAM, which allows more applications to run simultaneously, although the speed of access to such a "RAM" will be lower than to physical memory.
⚠️ Warning: Getting Root rights automatically voids warranty on Xiaomi device. Misconduct when modifying system files can turn a smartphone into a brick».
The process of creating a swap file usually takes a few minutes. After activation, you need to restart the device and check the status through the terminal with the free -m command. If everything goes well, you will see an increased value of available memory.
Risks of using a Swap file
Comparison of methods for increasing productivity
The choice of optimization depends on your technical skills and the goals of using the smartphone. Native MIUI tools are safe, but give less gain, whereas Root methods are more powerful but riskier.
The table below compares the main characteristics of the different approaches to increasing the available memory on the Redmi 8 Pro.
| Method | Security | Efficiency | Difficulty |
|---|---|---|---|
| Native expansion | Tall. | Medium | Low. |
| Developer settings | Tall. | Low. | Low. |
| Swap through the Root | Low. | Tall. | Tall. |
| Third-party boosters | Medium | Low. | Low. |
💡
Native memory expansion is the middle ground for most users, which does not require deep knowledge and retains a guarantee.
Cleaning the system and removing bloatware
Often the problem is not a lack of physical volume, but a cluttered system. Xiaomi smartphones are pre-installed with a lot of advertising modules and unnecessary services that are constantly hanging in RAM.
Use ADB AppControl on your PC to safely remove system debris without getting Root permissions. Connect your phone over USB, enable debugging and start scanning. The program will show you which packets can be removed without harming the system.
- 🗑️ Remove apps with names MSA, Daemon, Analytics are advertising trackers.
- 📉 Turn off auto-run for all applications except instant messengers in the Security menu».
- 🧹 Clean the app cache regularly through a standard cleaner, but don't abuse "accelerators».
After removing the excess software, restart the device, and you will notice that there is much more free memory, and the interface works smoother even without using swap files.
