How to Unload RAM on Xiaomi: Expert Guide

Modern Xiaomi smartphones, which run on the shells MIUI or HyperOS, are equipped with powerful processors and a significant amount of RAM. However, even flagship models can over time face slowdowns, long opening of applications or their sudden closure, often due not to a lack of hardware resources, but to inefficient management of software processes and accumulated “digital garbage”.

Understanding how RAM works in the Android ecosystem helps users manage device resources wisely. Unlike permanent memory, where your photos and files are stored, RAM serves as a temporary storage for running applications. The more programs open at the same time, the more the load on the system. Forced cleaning of all processes at once often leads to the opposite effect - the system spends more energy on restarting services.

In this article, we will take a closer look at optimization techniques that really work on Redmi and Poco devices, and learn how to distinguish between secure settings and marketing tricks, and understand when to intervene and when to trust built-in optimization algorithms.

Diagnostics of the current state of the system

Before you start taking action to free up resources, you need to determine exactly what consumes the memory of your smartphone. Xiaomi’s built-in diagnostics tools provide enough information, but for deep analysis, it is better to use advanced developer tools. The standard settings menu often hides real consumption figures.

To access hidden features, activate developer mode. Go to Settings → About your phone and find either MIUI Version or OS Version. Click on it 7-10 times in a row before the notification that you have become a developer appears.

In the Developer Menu, find the Memory section or use the adb shell dumpsys meminfo command to get a detailed report through your computer, and not only does it show free volume, but it also lists the processes that are consuming the most resources right now. Pay attention to high value applications PSS (Proportional Set Size).

Basic cleaning with built-in MIUI and HyperOS

Xiaomi’s shells have deeply integrated tools to maintain the system, and the easiest way is to use the standard Security app, which automatically analyzes the system’s status and suggests that temporary files be deleted or background applications be closed.

But blind trusting the Clean button is not always effective. The system often shuts down processes you need or leaves heavy services behind. For more spot work, open the Security app, go to Accelerate and click on the settings icon (cogs), where you can exclude important apps from auto-cleaning.

Also worth noting is the memory extension feature, which allows you to use part of the permanent memory (ROM) as an additional RAM (RAM), although this helps keep more applications open, the speed of this memory is lower than that of a physical RAM.

⚠️ Attention: Using the memory expansion feature increases the wear of the drive. if you have 8 GB RAM and more, it is better to keep this feature off to extend the life of the phone.

Managing Autoboot and Background Processes

One of the main reasons for the lack of free memory is the excessive activity of applications in the background: social networks, instant messengers and news aggregators tend to start their services immediately after turning on the phone, and this process can be controlled through battery settings and special permissions.

Go to Settings → Apps → All Apps. Select a demanding app (like Facebook or Instagram) and go to Energy Saving. Set a background activity limit. This won’t delete the app, but it will stop it from consuming resources when you’re not using it directly.

Also, check the AutoStart section of the Security app, which shows the list of programs that start with the system, leave only messengers (for notifications) and system services on, and other applications, such as marketplaces or games, you can safely turn off.

• 🚀 Optimize: Turn off auto-runs for apps you use less than once a day.
• 🔋 Battery: Restricting background activity will have a positive effect on battery life.
• 🔔 Notifications: With a strict background restriction, notifications from some applications may come with a delay.

Using Developer Mode for Advanced Users

For those who want to get maximum control of the system, the developer mode offers fine-tuning tools, which can limit the number of background processes that can run simultaneously, a radical but powerful method for older, low-volume RAM devices.

In the Developer menu, find the item "Background Process Limit" and the default item is "Standard Limit," and if you change the value to "No More than 2 Processes" or "No Background Processes," you force the system to unload applications from memory immediately after you fold.

Also in this section, there's the option "Do Not Stay Activated." If it's enabled, the system will destroy the active screen of the application as soon as the user leaves it. This is useful for testing, but in everyday use makes navigation twitchy and uncomfortable. Use this feature with caution.

Comparison of methods of memory optimization

There are many ways to try to speed up a smartphone, but not all are equally effective and safe. Below is a table comparing the main methods of memory offloading, their impact on performance and potential risks.

When choosing a method, start from your device model. Basic cleaning is enough for flagships with 12 GB of memory, whereas budget models with 4 GB may need a combination of several methods, including limiting background processes.

💡

Reboot your smartphone periodically (every 3-4 days) This is the only way to completely clear the system cache and reset the accumulated errors in the work of services without losing data.

Frequently Asked Questions (FAQ)

💡

The optimal strategy for Xiaomi is to disable auto-run unnecessary apps and a rare reboot, not constantly manually clean up memory.
