How to check the memory status on Xiaomi Redmi: from basic settings to hidden features

Xiaomi Redmi smartphones are famous for their excellent price-performance ratio, but over time, even the most powerful devices can start to work slower. Often the root of the problem lies in overflowing system memory or incorrect work of the operational buffer. Users notice lags, sudden drops of applications and long switching between tasks, which significantly reduces the comfort of using the gadget. Understanding how resources are allocated is the first step to optimize the operation of your device.

Android, which runs the MIUI or HyperOS shell, has many hidden processes that consume resources in the background. Standard monitoring methods don’t always give a complete picture of what’s happening, hiding important technical details from the user. In this article, we’ll go through all the diagnostic tools available, from simple built-in tools to advanced methods for power users who want to gain full control of their device.

Basic verification through storage settings

The easiest and most affordable way to assess internal storage capacity is to use the regular settings menu, which is to go to Settings → About Phone → Storage, where the system provides a graphic diagram showing how much space is occupied by the system, applications, images, videos and other files, and it's the primary tool to quickly understand if the free space limit is not exhausted, which is often the main cause of brakes.

But you have to consider that the standard MIUI interface can aggregate data in ways that are not exactly accurate, by merging some system caches into a bunch of "Others." If you see that the "Other" category is a suspiciously high gigabyte, that's a signal that you need to clean up more deeply. System debris can accumulate for months, especially if you're actively using messengers like Telegram or WhatsApp that cache media files.

💡

Use the built-in Security app to quickly clean up garbage, but don’t rely on it completely – it often leaves deep app caches intact.

It is important to monitor this partition regularly, as filling up more than 90% of the storage can lead to serious failures in the file system. Android requires free space to create temporary files and normal operation of virtual memory mechanisms. Ignoring these indicators can lead to situations where the phone will stop accepting calls or updating applications.

Monitoring of RAM (RAM) in real time

Unlike permanent storage, RAM only works with data while the device is on. To see how much RAM is available right now, you can use the developer menu or floating windows. In standard mode, Recent Tasks (the menu button or swipe at the bottom) often display a clearing button and current free memory, such as "5.2 GB free." This is a basic level of control.

For more detailed analysis, you need to activate the developer mode. → About the phone and quickly press 7 times on the item "Version" MIUI" or "Version." OS". After that, a new section will appear in the menu called "Additional" or "Extended settings" where you can find "Developers" and inside this section, you can find "Memory" or "Running Services" which will show you a detailed list of processes and the amount of work they take. RAM.

⚠️ Warning: Do not try to force system processes to close down in the developer menu unless you are sure of their purpose. UI Google Play Services may result in a reboot of the interface or loss of communication with servers.

Also worth noting is the memory extension feature that is available on many modern Redmi models, which allows you to use part of the permanent storage as virtual RAM, and check its status under Additional → Expansion of Memory. Enabling this option can help if you have little physical RAM, but can slightly reduce the speed of the drive due to additional write cycles.

Using the CIT Engineering Menu for Diagnostics

The most accurate information about the state of hardware components, including memory, is provided by the CIT (Customer Integration Test) engineering menu, a hidden section designed for factory testing, but also accessible to ordinary users. To enter it, you need to open a standard telephone dialer and dial the command ##6484##. If the code is entered correctly, the list of tests will open.

The list of tests should look for items related to Memory, Storage or RAM. It shows not just volume numbers, but the results of checking the integrity of memory cells and the presence of read / write errors. This is the only way to see raw data about the health of memory chips without installing third-party software. If the test shows errors (Fail), this may indicate physical degradation of the drive.

Sometimes the menu can be blocked by a carrier or firmware, and in such cases, use alternative codes like ##4636##, which opens the test menu, and you can find uptime and resets in the "Statistics" section, which indirectly indicates the stability of the system, but for deep memory diagnostics, CIT is the most authoritative source.

Analysis of occupancy through computer and ADB

For users who aren’t afraid of the command line, there is a powerful Android Debug Bridge tool available (ADB). Connecting the smartphone to the computer through USB-cable and switching on debugging USB, You can get a detailed report on the state of the memory partitions. The adb shell dumpsys meminfo team provides detailed usage statistics. RAM each process, including hidden system services that are not visible in the interface.

adb shell dumpsys meminfo | grep -i"Total RAM"

This command will allow you to quickly see the total volume and free space. Moreover, with ADB you can analyze the use of storage by the adb shell df command, which will show the occupancy of all parts of the file system, including the system partition, which is usually hidden from the user. This is useful for detecting anomalies when the phone says "Memory is full", although the gallery is empty.

Using ADB requires a lot of preparation: installing Xiaomi USB Drivers and SDK Tools on a PC, and while it’s complicated, it gives you the most transparent picture of what’s going on inside Android, and you can see if a particular log file or cache has bloated, taking up gigabytes of space.

Third-party applications for in-depth analysis

If the built-in tools don’t seem informative enough, Google Play’s dedicated apps come to the rescue, with CPU-Z or DevCheck Device & System Info being the leader in this field, providing comprehensive information about the type of memory (LPDDR4X, LPDDR5), its frequency and current real-time loading with graphs.

Another powerful tool is DiskUsage, which visualizes the contents of your storage as a block map, and you can immediately see which folder or application takes up the most space, even if it's a hidden cache that doesn't show up in the standard settings. Visualization helps you instantly find "eaters" of space that may have been lost in the depths of the file system.

⚠️ Warning: Be careful with the "2x speed" software that promises to "boost the phone" -- many of them only aggressively unload apps from the phone. RAM, causing the system to reboot them, which consumes battery and processor resources.

Optimizing and Resolving Memory Problems

After a diagnosis, the question often arises: what to do with the data received? If the storage is full, the first thing to do is to clear the cache of heavy applications (YouTube, TikTok, Instagram). In MIUI, this is done through Settings → Apps → All Apps → [Select App] → Memory → Clear cache. Don’t confuse it with Clear all data, as this will delete your logins and settings.

For RAM, setting up a startup is an effective method. Go to the Security app → Permissions → Auto Start and leave only the most necessary applications (messengers, alarm clock) on. The rest of the programs do not need to work constantly, consuming precious megabytes of RAM.

Regularly restarting the device also helps to reset accumulated memory management errors. Xiaomi has a “Planned on and off” feature that can be configured at night, which ensures that every morning the phone starts working from a “clean sheet”, without any hanging processes.

💡

Regularly cleaning the messenger cache and disabling auto-run of unnecessary applications solve 80% of memory problems on Redmi.
