Owners of budget smartphones often face a lack of computing resources when working with modern applications. Xiaomi Redmi 8 model came to the market as an affordable solution, but over time, the regular 3 or 4 GB of RAM becomes insufficient for comfortable multitasking.
Increasing the available RAM is not just a way to speed up the device, but also an opportunity to extend its active life. Current versions of the MIUI shell are quite resource-intensive, and standard optimization tools may not be enough. In this article, we will examine both software and hardware methods of expanding memory, and also assess the real risks of each approach.
It is worth noting that physically adding a memory chip to a phone is impossible without the sophisticated hardware and skills of soldering BGA. However, there are proven software algorithms that allow you to redistribute system resources. Using a paging file on an internal drive is the only safe way to emulate additional RAM without losing warranty.
Analysis of the current situation and limitations of Redmi 8
Before you start modifying the system, you need to clearly understand the architecture of your device. Xiaomi Redmi 8 is built on the basis of the Snapdragon 439 processor, which has certain limitations on memory bandwidth. RAM here is like LPDDR4X, and its volume is strictly limited by the processor controller.
MIUI's regular optimization tries to keep the most commonly used applications in mind. However, data compression algorithms don't always work efficiently. When the free RAM volume is exhausted, the system begins to aggressively reset background tasks, manifested in the form of delays when switching between windows and long reboots of "heavy" programs.
It's important to distinguish between physical and virtual memory. Physical memory is chips soldered on a board. Virtual memory is created by software by reserving space on an internal drive. Virtual memory is much slower than it is, so there's no miracle of turning a public-sector into a flagship, but there's more stability.
⚠️ Note: Any manipulation of system files and obtaining superuser rights may result in loss of warranty.Be sure to save data in the cloud or on external media before starting any actions.
Users often confuse a lack of RAM with a lack of storage space for files. Freeing up disk space will not add megabytes to RAM, but can improve overall system responsiveness. Use the developer's built-in tools to diagnose the current state.
Cleaning and optimization with MIUI staff funds
The first step to freeing up resources is to set up the system properly, with the MIUI shell having many built-in tools that users often ignore, and the proper management of background processes allows you to release up to 20-30% of RAM without third-party software.
In the settings menu, you need to find the App section and go to managing boot, disable startup for all applications that you don't use daily, and this will prevent them from running hidden in the background and consuming CPU resources.
- 🚀 Open the Settings. → Advanced settings → For developers, find the limit of background processes by setting the value of "No more than 2".
- 🗑️ Use the built-in Cleanup utility regularly, but don’t rely on it alone – it often doesn’t unload system services.
- 📉 Remove or freeze system applications that you do not use (e.g. Mi Video, Mi Music, if there are analogues).
There's also Extension Memory, which came out in newer firmware versions, which allows you to reserve some of your internal memory for RAM. Check if this option is available in the Additional → Extension Memory section. If the switch is active, turn it on and restart the device.
The effectiveness of the standard methods depends on the version of Android and MIUI. On older builds, the cleaning algorithms work worse. So updating the firmware to the latest available version is also a way to optimize memory management, as Xiaomi engineers constantly improve the work of the task scheduler.
Use of a swap file (SWAP) without Root rights
Creation SWAP-Partitioning is a classic method of increasing the available amount of memory in Linux-like systems, which includes Android. On modern versions of Android without superuser rights (Root) to create a full-fledged system. SWAP-The section is complicated, but there are emulator applications that work to bypass the restrictions.
One popular solution is to use booster applications that emulate memory work. However, most of them simply clear RAM. The real extension requires a dedicated container file. Some launchers and optimization utilities offer this feature in premium versions.
Without Root access, Android security blocks direct access to low-level kernel commands, so methods without administrator privileges are often temporary or less efficient, and can help in a critical situation when you need to run a heavy game, but will not solve the problem globally.
💡
Before installing any memory apps, check their rating and the date of the last update. Older utilities may conflict with newer versions of Android 9 and 10.
If you’re not ready to get Root rights, focus on using Lite versions of apps. Social networks and instant messengers have lightweight counterparts that consume significantly less RAM. Replacing the main Facebook with Facebook Lite can save up to 150 MB of RAM in the background.
Getting Root Rights and Installing SWAP through Magisk
To solve the problem, you need to unlock the bootloader and get the Root rights. This is the most effective, but also the most risky method. Unlocking the bootloader on Xiaomi devices requires waiting 168 hours (7 days) after you associate your Mi Account in the Mi Unlock application.
After unlocking Bootloader, you need to install custom recavers (for example, TWRP) And the Magisk. Magisk Manager patch allows you to get Root rights in a system-safe way, and it's the presence of superuser rights that gives you access to the creation of real life. SWAP-file.
- 🔓 Unlock the bootloader through the official Mi Unlock Tool utility on PC.
- 📲 Install a custom Recovery TWRP, Compatible with Redmi 8 (codename: olive).
- 🔐 Please. ZIP-Magisk archives through recavities to obtain superuser rights.
- ⚙️ Install the Swap module or Swap No Root app (in Root mode) to create a swap file size 2-4 GB.
After setting up SWAP-The system will use internal memory as an addition to the RAM. Read and write speed on the internal drive Xiaomi Redmi 8 is quite high (eMMC 5.1), so the performance gains will be noticeable. SWAP It can reduce the life of flash memory of the phone.
☑️ Checklist before receiving Root
⚠️ Attention: Getting Root rights makes it impossible to work with banking applications and Google Pay. To get around you will need a complex setup of Root hiding through Magisk Hide, which does not guarantee 100% success.
Comparison of methods of memory expansion
The choice of method depends on your skills and willingness to risk the stability of the system. Below is a comparison table that will help determine the best way to solve the problem of resource shortages on the Redmi 8.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Cleaning and settings MIUI | Low. | Medium | Absent. |
| Booster applications | Low. | Low. | Advertising, data collection |
| SWAP without a Root | Medium | Medium | Instability of work |
| Root and SWAP-file | Tall. | Tall. | Loss of warranty, brick |
As you can see from the table, for the average user, the most reasonable trade-off is to deeply customize the regular funds and use Lite versions of applications. The method with Root rights should be chosen only by experienced enthusiasts who understand the risks.
Snapdragon 439 processor will remain the same and in heavy 3D-play-off FPS The main goal is to improve multitasking and speed of switching between applications.
