How to see the load of Xiaomi phone: full diagnosis

Xiaomi, Redmi and Poco smartphone owners often face situations where the device starts to run slower, heat up or discharge quickly. The first step in solving these problems is to accurately diagnose the current state of the system. Understanding how resources are allocated helps to identify background processes that consume energy and computing power without the user’s knowledge.

The MIUI operating system and its new version of HyperOS provide many monitoring tools, but some of them are hidden from the eyes of the average user. Standard settings do not always give a complete picture of what is happening under the hood of the gadget. For deep analysis, you need to use additional features, engineering menus and third-party utilities, which we will discuss in detail below.

In this article, we’ll take a look at all the available ways to check RAM, CPU and disk space loads. You’ll learn to use the hidden capabilities of Android to keep your device’s performance under full control and prevent possible crashes.

Standard Monitoring Tools in MIUI and HyperOS

It's always a good idea to start with the built-in tools, because they're the safest and don't require any additional software. Xiaomi's shell already has a Security app that aggregates the system's performance data, and it shows basic information about free RAM and free space on the internal drive.

To access more detailed statistics, you need to go to the settings menu, and here you can see a list of the applications that consume the most resources in the last day, which allows you to quickly identify the "gluttonous" programs that slow down the interface. Note the section "Battery", where you can often see a correlation between active CPU use and charge consumption.

⚠️ Note: The data in the standard menu is updated with a delay. If you just closed the heavy app, the statistics may show a few more minutes of high load, although the process is already completed.

To access advanced information right on the desktop, you can use widgets. They allow real-time tracking of free space in RAM. This is especially useful for models with a small amount of memory, where every megabyte is in account. However, standard widgets are usually not enough to view the CPU load.

Engineering menus and hidden codes for diagnostics

One of the most powerful tools for checking the load is the engineering menu, available through special tools. USSD-In Xiaomi phones, the main code for entering the test mode is ##64663##. Once you enter this combination, you will open a list of hardware tests where you can check the operation of the sensor, speakers and, importantly for us, see the status of the various modules.

However, to view the actual CPU load and memory, another code that opens the debugging menu is more useful: ##4636##. In the Test menu that appears, select Usage statistics. This displays detailed information about which applications and how much time they spent in active or background mode.

The interface of this menu may vary depending on the Android version and firmware, and in some cases, you can see the current device uptime and the number of reboots, which helps you understand how long it has been since the system hasn't been updated or reset, which directly affects the speed of work.

Using the engineering menu is safe if you do not change the settings, but only view the data. It is not recommended to reset usage statistics (Usage stats reset) without the need, as this will delete the history of the application, which you could analyze later.

Developer Mode: Real-time Monitoring

To get really relevant data on the download CPU In percentage, you need to activate Developer Mode. This is the standard Android feature, which is hidden by default. To unlock it, go to Settings. → About the phone and quickly press 7 times on the item "Version" MIUI" or “OS version".

Once activated, a new section will appear in the settings menu, "Additional" or "Extended settings", where you will find "Developers". We are interested in the item "Show CPU usage", when it is turned on in the upper right corner of the screen, a graph will appear showing the current load on the CPU cores in real time.

This tool is indispensable for finding the causes of lags, and if you see a graph jumping to 100% even on a desktop, it means that there is some kind of heavy process going on in the system, and there is also the option on this menu called Process Statistics, which shows how much RAM each application is running right now.

So after the diagnosis, the Display CPU Load function should be turned off, so it will return the interface to its standard view and save battery life.

Using ADB for detailed system analysis

For users who don’t have the standard methods, there is an advanced way to diagnose via computer using the ADB tool (Android Debug Bridge), which allows you to access system logs and see the load on each processor core separately, as well as the temperature of each module.

To get started, you need to enable debugging over USB in developer mode and connect the phone to the PC. Once you install drivers and platform tools, you can execute commands. For example, the command to view the total load of the processor is as follows:

adb shell top -m 10

This command will list the 10 processes that consume the most resources right now, and you'll see the process PID, username, CPU load percentage, and memory usage, and this is the most accurate way to understand what's eating your Xiaomi resources.

You can also get information about the temperature of the sensors, which is critical in diagnosing trottling (decreased performance due to heating).

adb shell cat /sys/class/thermal/thermal_zone*/temp

⚠️ Attention: Working with ADB Introducing the wrong root commands (if any) can cause the system to run in an unstable way. Use only get, cat, top commands if you are not an experienced user.

The advantage of ADB is that it doesn't load the phone with additional monitor apps, and it's all on the computer side, and the smartphone is just transmitting data, and it's the cleanest test results, excluding the effects of third-party software on the system.

Third-party applications for resource monitoring

If you don't want to mess with code and computer, Google Play's specialty apps will come to the rescue, with CPU-Z, AIDA64, and System Monitor leading the niche, providing a user-friendly graphical interface to display all the device's parameters.

The CPU-Z app is ideal for quickly checking the CPU model, its current frequency and number of active cores. It also shows the boot of each core individually, which is useful for assessing multitasking. Thermal tab (if supported by the device) can show temperature.

A more advanced tool is AIDA64, which is a real harvester that will tell you everything about the phone, from the battery voltage to the exact model of the screen matrix, and there's a separate "System" section to monitor the load, where you update the graphs in real time.

Installing these applications is a trade-off between convenience and resource consumption, and monitors themselves use CPU time to update data, so don't keep them running all the time unless you have to.

💡

Install only one monitoring application. Simultaneous operation of CPU-Z and AIDA64 can create a conflict of access to system files and cause additional battery drain.

Analysis and optimization after verification

Once you know how to see the load of Xiaomi phone and get the data, the analysis phase begins. If you see that RAM is 80-90% full in plain, that's a signal to action. In modern versions of Android, filling RAM is the norm for speeding up application launches, but critical filling leads to brakes.

High CPU load in the background is often associated with data synchronization, application updates, or malfunctioning of a particular service. In the process list (via ADB or developer mode), find an application with a high CPU percentage and try to clear its cache or reinstall it.

If memory overflow is the problem, use the built-in cleaning function in the Security app or manually delete the cache of heavy apps such as Telegram, Instagram or TikTok. These messengers and social networks tend to accumulate gigabytes of temporary files.

💡

Regularly restarting your smartphone (at least once a week) is the easiest and most effective way to reset accumulated errors in memory management and stop the hanging background processes.

In conclusion, constant monitoring is not always necessary, since Xiaomi’s healthy system is able to manage resources efficiently, but if you experience symptoms of a malfunction, the methods described above will help quickly localize the problem and fix it without going to the service center.
