How to check memory on Xiaomi Note 8 Pro: expert guide

Modern smartphones like the Xiaomi Redmi Note 8 Pro have impressive specs, but over time even the top-end hardware can start to work slower. Often the cause of performance is overflow or errors in the drive. The owner of the device may notice that applications have become longer to load, and the system periodically hangs when switching between tasks. This is the first signal that RAM or built-in storage require attention and possibly diagnostics.

Storage checks are not just cache cleansing, but a comprehensive analysis of how a device manages data. MIUI has powerful built-in tools that allow you to assess the state of the system without installing third-party software. However, deep analysis sometimes requires more advanced testing methods that will reveal hidden sector or registry problems, and understanding these processes will help extend the life of your gadget.

In this article, we will take a look at all the ways of checking available, from standard settings menus to hidden engineering tests, how to distinguish a software failure from the physical degradation of a memory chip, and what are normal for a model with a Helio G90T processor and what should be alarming. Get ready to dive deep into the technical aspects of your smartphone.

Built-in diagnostics in MIUI

The easiest and safest way to start checking is to use the regular Security app, which is preinstalled on every Xiaomi device, which scans the system for malicious files, analyzes resources and offers optimization. Once you run the scan, you get basic information about free space and RAM load, the system automatically closes the background processes that consume excess resources, which can temporarily speed up the interface.

But the standard scanner doesn't show detailed information about the health of the drive, such as cell wear or read/write speed. To get more accurate data, you need to go to the expanded settings menu, and you can see which apps are taking up the most space and how long they've been active, which helps identify resource eaters that are quietly slowing down the Redmi Note 8 Pro.

⚠️ Warning: Don't rely on a standard cleaner.It often only deletes temporary files, leaving deep registry errors or fragmentation unaddressed.

For a deeper analysis, there is a section called Cleanup inside the Security app, where you can study the contents of folders in detail. Here, be careful: removing system logs or cache of important services can lead to unstable operation of the operating system. It is recommended to clean only user debris, such as the remnants of deleted applications or temporary messenger files. Regularly checking these partitions helps keep the device in good shape.

⚠️ Note: When you clean these apps through settings, you will lose saved passwords and game progress if you don’t make a backup.

Using CIT's Hidden Engineering Menu

Xiaomi smartphones have a special engineering menu known as CIT (Customer Integration Test) designed for factory diagnostics and allows you to check every component of the device, including memory modules. To get there, you need to open the Phone app and dial the combination ##6484##. If the code is entered correctly, a list of tests will open where you can choose to check Storage or Memory.

In this menu, the test is done automatically, and the system records the test data to the disk, reads it, and compares it for errors, and it can identify broken sectors or memory controller problems that are not visible in normal operation. If the test is successful, you will see a green "Pass" sign, and if errors are detected, the system will issue a warning, which may indicate that the storage device itself or the storage device needs to be replaced.

What to do if the CIT test does not start?
If nothing happens when you enter the code, you may have a global firmware version with a stripped menu installed or superuser rights blocking access. Try entering the code through Google's Phone app or use third-party utilities to run Activities.

It's important to understand that the tests in CIT load the device, so the phone can get hot. This is the normal reaction of the Helio G90T processor to a high computing load. Don't interrupt the verification process until it is complete, otherwise the results may be incorrect. After the test, be sure to press the exit button or restart the device to reset temporary test files.

Checking RAM through the developer settings

For advanced users who want to control RAM in real time, Android has a special option. To activate it, go to Settings → About phone and quickly click on the MIUI version seven times. Once the notification “You became a developer” appears, a new menu will open in the “Additional” section, where you need to find the item “Memory Status” or “Running Services” and activate it.

Once this feature is enabled, a floating window will appear in the list of running applications, showing how many megabytes of 6 or 8 GB are occupied right now, which allows you to monitor in real time how different programs affect RAM, for example, you can run a heavy game and see how much resources it eats up, or check if the memory is leaking in the background after the application is closed.

Having plenty of free memory isn’t always good: Android is designed to keep frequently used applications in RAM for quick launch. However, if less than 500MB of free memory is left all the time, it’s a sign that the system lacks resources to work comfortably, and it’s worth considering resetting or removing rarely used software.

💡

Use the memory statistics widget to understand which application is eating up resources. If the memory is not released after closing the browser, this is a sign of a leak.

Testing the speed of reading and writing the drive

The type of memory installed in the Xiaomi Redmi Note 8 Pro directly affects the speed of downloading games, installing applications and copying files. This model uses the UFS 2.1 standard, which is much faster than the old eMMC. To test the real speed of your instance, you can use specialized benchmarks such as AIDA64 or AndroBench. These utilities conduct a series of tests for sequential and random read/write.

Normal performance for this model should be close to the following values: sequential reading of about 500 MB / s, writing - about 400 MB / s. If your results are significantly lower (for example, reading below 300 MB / s), this may indicate severe data fragmentation, overflow of the drive or degradation of the chip.

Parameter of the testNorma (MB/s)Critical levelImpact on work
Sequential Read450 - 550< 300Downloading OS and applications
Sequential Write350 - 450< 200Saving photos and files
Random 4K Read100 - 150< 50Opening the menu, multitasking
Random 4K Write80 - 120< 40Installation of updates, cache

When performing tests, it is important that the phone is charged at least 50% and not connected to the computer via USB, as this can limit the speed of the bus. Also close all background applications before running the benchmark for the cleanest results. Repeat the test 2-3 times and take the average, as the first run can be distorted by caching.

💡

The low random read speed (4K Random Read) affects the overall smoothness of the system more than the performance of sequential writing.

Occupancy analysis and cleaning of system debris

When an internal drive is more than 90% full, its speed drops exponentially, due to the features of the memory controller, which lacks free blocks to write new data and move files. In the Xiaomi Redmi Note 8 Pro with a capacity of 64 GB, this can become critical quite quickly.

And the special attention we need to pay to folders like Telegram and WhatsApp, which tend to accumulate gigabytes of media that are often duplicated in the gallery, and the built-in storage analyzer allows you to visualize which file types are taking up the most space, and it often turns out that half of the memory is occupied by long-forgotten videos or backups.

  • 📸 Gallery: Check the cart, deleted photos are stored there for 30 days and take up space.
  • 💬 Messaging: Clear the cache of channels and groups, leaving important documents.
  • 📲 Remove games you haven’t played in more than a month.
  • 🗑️ Download: Download folder is often clogged with installers APK, which are no longer needed.

There is a myth that microSD cards slow down your phone. In the case of the Redmi Note 8 Pro, which supports fast cards, this is not quite true, but installing apps on a flash drive can really reduce their performance. It is better to store only media files on an external card, and leave the system and heavy applications on an internal fast drive.

Third-party utilities for deep diagnostics

If there's not enough built-in tools, third-party apps from Google Play come to the rescue, and one of the leaders in this field is CPU-Z or DevCheck, which provide detailed information not only about the processor, but also about the type of memory, its frequency and current load, and this data is useful for comparing it with the reference values of your model.

Another useful tool is Files by Google, which not only shows busyness, but also cleverly suggests removing duplicate photos, blurred images and old screenshots. The app's algorithms analyze content and find files that can be safely deleted, freeing up precious megabytes, and this is especially true for users who are actively taking high-resolution photos.

⚠️ Note: Avoid installing "memory accelerators» (RAM Boosters, which promise miraculous speed gains, often consume resources themselves and force the processes that the system immediately rediscovers, creating extra workload.

For professional analysis, you can use the Disk & Storage Analyzer app, which charts memory occupancy and shows which folders are growing the fastest, and it helps you find an application that, for example, caches video in the background, stealthily eating up all the free space, and regular monitoring with these tools helps prevent sudden space shortages.

Why is the memory occupied by 20 GB after reset?
System files, pre-installed Google and Xiaomi apps, and backups take up a significant amount of space. MIUI.

Frequently Asked Questions (FAQ)

Why did the MIUI update fill up the memory?
After a major update, the system backs up old settings and files, and caches new interface resources. Usually, after 2-3 days of active operation, the cache is cleared automatically, but you can speed up the process by restarting the device a couple of times.
Can I increase the memory capacity on the Xiaomi Note 8 Pro?
Physically, you can't increase your internal memory (eMMC/UFS) without soldering chips in the service center, which is difficult and expensive, but you can expand your storage for photos and videos by installing a microSD card up to 256 GB in a special slot.
How to check if your phone’s memory is dying?
Indirect signs are frequent freezes, long file write-ups, errors in installing applications and sudden reboots, and only a test in the CIT engineering menu or the AndroBench benchmark, which shows critically slow speed, will give the exact answer.
Is it safe to use memory expansion?
Newer versions of MIUI have a feature to expand RAM to internal memory, which can help with multitasking, but increases the wear and tear of the drive. If you have 6 or 8 GB of physical memory, it's best to keep this feature off to save the life of the phone.
