How to see the consumption of RAM Xiaomi: full instructions

Modern Xiaomi and Redmi smartphones have a huge amount of RAM, but even 8 or 12 GB can be fully loaded in the process of active work. Users often face a slowdown in the interface, sudden closure of background applications or friezes in games, without understanding the reason. RAM is a critical resource on which the speed of switching between tasks and the overall responsiveness of the MIUI or HyperOS system depends.

Many device owners mistakenly believe that the built-in cleaner always shows the real picture, but system widgets often hide details of the background. To conduct a full diagnosis and understand why the phone is slowing down, you need to look deeper than the standard interface. There are several proven ways to access detailed resource usage statistics, including hidden engineering menus and debugging tools.

In this article, we’ll look at all the monitoring methods available, from simple built-in features to advanced analytics tools, learn to distinguish between system consumption and voracious applications, and understand when to really worry about a lack of resources. It’s important to understand that filling in RAM on Android is a regular situation, not always a sign of a malfunction or a virus.

Using built-in monitoring in settings

The most accessible way to get your primary memory status information is in your device’s standard settings menu. MIUI’s Android system provides a basic but useful tool for assessing your current load. To use it, go to Settings → About Phone → Memory (the path may vary slightly depending on the firmware version).

This shows the total amount of memory available and the amount of space occupied in real time, but this screen only shows the tip of the iceberg and does not detail which application is consuming the most resources right now.

If a standard desktop widget shows critically low free memory values, it doesn’t always mean a problem. The memory algorithms in modern Android versions are designed to maximize the available volume to speed up the launch of frequently used programs. Forced cleaning can even harm performance by forcing the processor to reload data to RAM cells.

• 📱 Go to Settings and find the Advanced Settings item.
• 🔍 Open the Memory section to view basic statistics.
• ⚙️ Pay attention to the usage schedule for the last hour or day.
• 🧹 Use the “Clear” button only when the interface is clearly frozen.

⚠️ Warning: Don't blindly rely on the percentage of free memory. If the system is running smoothly, fill in 70-80% RAM is the normal mode of operation of caching.

For most users, built-in monitoring is enough to assess the overall condition of the device, but if you notice strange behavior, you should resort to more professional analysis tools.

Activation of the developer mode and advanced statistics

To get detailed information about how many megabytes each application is eating, you need to activate the hidden developer menu. This is a standard procedure for Android smartphones that gives access to dozens of useful diagnostic features. You need to find the MIUI version (or OS version) in the About Phone menu and quickly click on it 7-10 times in a row.

After the “You’ve become a developer” notification appears, a new section will appear in the settings menu Additional → For Developers. We are interested in the Memory or Running Services item, which displays a list of all active processes with an exact indication of the amount of RAM occupied. Here you can see not only user applications, but also system services that often go unnoticed.

This menu also includes a back-end limiting feature, which means you can force the system to prevent more than a certain number of applications from being stored, and be careful: an aggressive restriction can disrupt messengers, alarms, and system notifications, which will cause important calls to be missed.

Analysis of the list of running services reveals “parasitic” processes that are not visible in a normal task manager, often hanging after removing games or using heavy editors, gradually “eating” resources and causing the case to heat up.

Engineering menu and testing of CIT equipment

One of the most reliable ways to check the technical condition of RAM is to use the CIT (Customer Integrated Test) engineering menu, a diagnostic tool built into the firmware in the factory to test components before sale, accessed through a special code in the Phone application.

To enter the menu, dial the combination ##6484## or ##4636##. If the code does not work, it is possible that your version of the HyperOS shell blocks direct access, and then you will need to install a special activator application from the GetApps store. In the CIT menu, you need to select the item associated with memory testing (usually called Memory or RAM Test).

RAM will be loaded with cyclic data to check for read and write errors, which can take anywhere from 5 to 15 minutes depending on the amount of RAM you have, and you will get a report at the end: if the test is successful, the physical memory modules are in good working order and the problem is in the software.

If the test shows errors, it indicates a hardware malfunction of the memory controller or the chips themselves, in which case software optimization methods are useless, and you need to contact a service center to replace the motherboard or solder the chips.

Third-party applications for in-depth analysis

When built-in tools are scarce, Google Play offers specialized tools, applications like CPU-Z, AIDA64 or DevCheck that provide comprehensive information about the specifications of a smartphone, not only current consumption, but also memory type (LPDDR4X, LPDDR5), frequency and number of channels.

The use history feature in these applications is particularly noteworthy, and it allows you to plot memory usage over the past hours or days, and it helps you identify patterns: for example, you notice that after you run a particular social network, memory is not released even after it is closed, which is a sign of a memory leak in the application code.

Using third-party cleaners often does more harm than good, aggressively unloading processes from memory, forcing the system to restart them, which increases battery consumption and processor load, and using monitoring tools rather than automatic cleaning.

It is recommended to install a CPU-Z or analogue to check the characteristics and compare them with the manufacturer's declared, this is especially true when buying a used device to make sure that you are not sold a re-energized clone with less memory.

Use of debugging by USB and ADB

For advanced users with access to a computer, the most accurate tool is USB debugging. ADB (Android Debug Bridge) allows you to get raw data directly from the kernel of the system, bypassing the interface limitations, you need to connect your smartphone with a cable to the PC and execute a command in the terminal.

First, you need to activate USB debugging in the Developer menu, then, after installing the platform tools on your computer, type a command to get a detailed memory report:

adb shell dumpsys meminfo

This command will show you a huge list of all processes, with their memory in kilobytes, and you'll see the division into Private Dirty, Shared Dirty, and PSS, which is the most professional way to find the culprit for the lack of resources.

Analyzing dumpsys meminfo output may seem difficult to a beginner, but the key numbers are at the top of the report, where the sum of memory usage by the system and applications is summarized. If the amount is very different from the physical volume of RAM, perhaps some of the memory is reserved for the needs of the GPU or other hardware modules.

⚠️ Attention: When working with ADB Be careful with commands containing the words "kill" or "stop." Incorrectly completing the system process can lead to a phone restart or loss of unsaved data.

Using ADB is especially useful when the phone is unstable but the interface is still responsive.You can remotely see what process is causing the load, even if the smartphone screen is getting stuck.

Optimization and Memory Management in MIUI

Once you've identified memory problems, you need to set up the system to work smoothly. MIUI and HyperOS shells have aggressive background management policies that you can flexibly adjust. The first step is to turn off Virtual RAM if you already have so much physical memory.

The Memory Extension feature takes a portion of the built-in storage and uses it as RAM. While this sounds useful, the speed of flash memory is well below the speed of RAM chips. Enabling this option on devices with 8GB or more can even reduce overall performance and increase wear and tear on the drive.

Also, check the power saving settings for specific applications, if you care about a program (such as a navigator or messenger), set background activity limits for it in the “No Limits” mode, which will prevent the system from ending the process prematurely in order to save charge.

💡

Turn off the memory extension feature in the settings if you have 8GB of RAM or more, which will reduce the load on the built-in drive and can speed up the interface.

Regularly restarting your device (at least once a week) also helps to reset accumulated system errors and free up fragmented memory blocks, a simple but effective preventive measure for any smartphone.

💡

Competent setting of background activity restrictions is more important than manual memory cleaning through widgets.
