Owning a modern Xiaomi or Redmi is always a balance between impressive performance and real speed in everyday tasks. Often users wonder how to objectively assess the power of their device to understand whether to wait for lags in heavy games or multitasking. Performance testing is not just running a single program, but a comprehensive analysis of the operation of the processor, graphics accelerator, RAM and cooling system.
Standard assessment methods can only give a superficial idea of the capabilities of the gadget. To obtain reliable data, you need to use specialized tools that create a controlled load on the hardware components. In this article, we will discuss how to conduct a deep diagnosis of your smartphone using both built-in MIUI or HyperOS shell functions and third-party professional solutions.
Don’t just rely on the numbers in the specifications, because software optimization is crucial. Even a powerful chipset can run slowly due to background processes or overheating. We’ll look at techniques to help you identify hidden issues and make sure your Xiaomi delivers the power it claims.
Use of built-in diagnostic tools MIUI and HyperOS
The first step before installing third-party software should always be the use of native system tools. Xiaomi shells are equipped with a sufficiently advanced security module that can not only look for viruses, but also perform basic system optimization. This tool is available out of the box and does not require configuration, making it ideal for quick verification.
To access basic diagnostics, you need to open the Security app and select Clean or Accelerate. The system will automatically analyze running processes and memory usage, suggesting that you close background applications. However, for deeper analysis, you should use the engineering menu or hidden tests.
💡
To access the extended testing menu, dial ##64663## in the Phone app, which will open the CIT Engineering Menu, where you can check individual hardware modules, including sensors and vibration.
It's important to understand that embedded tools only show the current state of the system, not the limits of its capabilities. They're good at spotting software "latches," but they don't answer the question of the actual power of the GPU. So we're going to go to more serious tools.
💡
The built-in MIUI/HyperOS tools are suitable for quick memory cleanup and basic module health checks, but do not replace full-fledged benchmarks.
Professional benchmarks: AnTuTu and Geekbench
The gold standard in the mobile diagnostics industry has been synthetic tests for years, which load a device using specific algorithms to produce a score that compares to other models, and the most popular solution for Android smartphones, including Xiaomi, is the AnTuTu Benchmark.
This comprehensive test checks the performance of the CPU (processor), GPU (graphics), UX (user experience) and MEM (memory). After running, you get detailed statistics showing exactly where your device is strong or weak. For the CPU part, Geekbench is often used, which focuses on the speed of computing in single and multi-core modes.
- 🚀 AnTuTu: Gives a big picture of performance, including interface loading speed and image processing.
- 🧠 Geekbench 6: Perfect for comparing CPU core power between different architectures.
- 🎮 3DMark: Specializes in testing graphic performance, which is critical for gamers.
- 📊 CPU Throttling Test: Shows how quickly the device reduces frequencies when heated.
⚠️ Warning: During benchmarks, the smartphone can get very hot, this is a normal reaction to high load, but if the device gets too hot, it is better to interrupt the test to avoid damage to the battery.
When interpreting the results, it is important to consider the operating system version and security updates installed. Different versions of Android may show different performance on the same hardware.
Temperature monitoring and system trottling
One of the main reasons for the performance decline on Xiaomi smartphones is thermal trottling, a protective mechanism that forcibly reduces the clock speed of the processor when critical temperatures are reached. To test how your device copes with heating, it is not enough just to start a game.
Real-time monitoring applications such as the Throttling Test CPU or the Device Info HW. These snails display the current temperature of each CPU core in degrees Celsius. The normal operating range under load is 40–50°C, but short-term jumps to 60°C are acceptable for flagship models.
What is trolling?
If you notice that after 10-15 minutes of active operation, the smartphone starts to work slower, then the cooling system is not coping, in this case, it is worth checking whether the ventilation compartment is closed with a cover, and try to reduce the graphical settings in the applications.
Prolonged operation at temperatures above 70°C can lead to battery degradation and detachment of plumes inside the enclosure.
Checking the stability of the memory
The speed of the interface and the ability to keep applications in the background directly depend on the quality and speed of RAM. Xiaomi devices often use virtual memory expansion technology, when part of the storage is borrowed for RAM.
You can use MemTest, or some benchmarks' built-in features, to test for write and read errors, and to check for stability when filling 90-95% of the available volume, and if the system starts killing background applications too aggressively, there may be a lack of physical memory.
Note the type of memory installed. Xiaomi’s current flagships use the LPDDR5 or LPDDR5X standard, which provides significantly higher bandwidth than LPDDR4X. This is especially noticeable when running heavy games and working with the camera.
☑️ Memory diagnostics
Memory dysfunction can be manifested in random system restarts or artifacts appearing on the screen. If benchmarks show errors in this module, it is recommended to make a complete data reset or contact the service center.
Testing of the display and touch layer
Performance is not just about computing, it's about the speed of the interface response. AMOLED-It is important to check whether the sensor is working correctly in the entire area with screens and high refresh rates (90, 120 Hz and above.
There is a simple and reliable way to test: run the test through an engineering menu or download the MultiTouch Test application, which allows you to determine the number of simultaneously recognized touches. Flagship models should support 10 touch points, budget ones - usually 5.
| Parameter | Norma. | Signs of a problem |
|---|---|---|
| Sensor survey frequency | 240 Hz and higher | Delays in games, “cotton” sensations |
| Multitouch | 5-10 points | The individual screen areas are not working. |
| Brightness (threads) | 500+ (locally 1000+) | Poor readability in the sun |
| SHEAM (shimmering) | High frequency | Eye fatigue with low brightness |
Also worth paying attention to the response time of the pixel. On quality Xiaomi matrices, the transitions between colors occur almost instantly, and if you see plumes behind moving objects on the menu, this may indicate software problems or poor matrix quality.
💡
To check the uniformity of the backlight and the presence of broken pixels, download any application with monochromatic images (white, black, red) and carefully examine the screen at maximum brightness.
Real-life scenarios: Gaming and multitasking
Synthetic testing is good, but there's no substitute for real-world testing. To understand how Xiaomi will behave in combat, run a resource-intensive game like Genshin Impact, PUBG Mobile or Call of Duty. Set maximum graphics settings and turn on the FPS counter.
As you play, pay attention not only to the average frame count per second, but also to the stability of your frame output. Stuttering is a sign of optimization or overheating issues. Many modern Xiaomi smartphones have Game Turbo mode, which is worth activating to prioritize resources.
Multitasking is tested by quickly switching between 5-10 heavy applications: Open a navigator, social network, game and browser with many tabs. If it is rebooted again when you return to an application rather than being deployed from memory, then the system is running out of resources.
⚠️ Warning: Do not use memory accelerators and Cliners while playing, they can force the necessary gameplay to close, which will lead to the opposite effect - lags and long loading levels.
The final performance score is summed up by all the factors: frequency stability, temperature, response speed and memory, and only a comprehensive approach will allow you to objectively judge the state of your device.
💡
The real test in games and heavy applications is more important than the points in benchmarks, since it shows the stability of the system under a long load.
