How to find out what occupies RAM on Xiaomi: a complete analysis

Owners of Xiaomi, Redmi and POCO smartphones often face a situation where the device suddenly starts to work slower, applications open longer than usual, and the system spontaneously unloads background programs. The main reason for this behavior in most cases is a lack of RAM. Unlike built-in storage, where photos and applications are recorded, RAM works with temporary data, and its overflow critically affects performance.

MIUI shells and the new HyperOS have resource management features that differ from pure Android. The system can aggressively close the background processes to save power, but sometimes “gluttonous” applications or system failures block the release of resources. To understand exactly where gigabytes of RAM go, you need to conduct deep diagnostics that go beyond the standard “About the phone” screen.

In this article, we will take a closer look at the built-in developer tools, third-party analysis tools, and manual cleaning techniques. You will learn to distinguish between system processes and user processes and understand when high memory load is the norm and when it requires intervention. Proper management of RAM will prolong the life of your gadget and ensure smooth interface operation.

Basic diagnostics through system settings

The first step for any user is to check the standard diagnostic tools that are already built into the firmware. Xiaomi provides the basic Security tool, which shows the overall picture of the load, but hides the details. To see more accurate numbers, go to the Settings menu → About phone → Memory. This shows the total amount of available and occupied memory, but the list of processes is often missing.

For detailed information, you need to activate a hidden menu. In the Memory section, some versions of the firmware have a Memory Use button that opens a list of running applications, sorted by consumption. However, this list does not always display system services that can consume a significant resource. System cache and Google Play services are often left behind.

If the standard menu doesn't answer, check the "Memory Extension" section, which uses a portion of embedded storage (ROM) as an addition to RAM. While this helps keep more applications open, using slow flash memory instead of fast RAM can cause micro-freezes, and turning it off sometimes frees up real resources for mission-critical tasks.

💡

On newer versions of HyperOS, the path to statistics may be hidden. Try quickly tapping 7-10 times on either MIUI Version or OS Version in the About Phone menu to open additional engineering tests if they are not blocked by the operator.

It's important to understand that standard settings only give a superficial view: they show which applications are running right now, but they don't explain why memory isn't released when they're closed.

Developer mode activation and real-time monitoring

The most effective way to see what is eating your memory is to use the built-in process monitor. This requires activating the developer mode. Go to Settings → About your phone and quickly click 7 times on the MIUI Version (or OS Version). Once the notification “You became a developer” appears, return to the main settings menu.

Now, the "Developers" section will appear in the "Advanced Settings" section, and search the "Running Services" option in the list, which shows the full picture: you'll see not only applications, but system processes like System Server, Media Scanner, or Xiaomi Cloud services, and you'll see how long the service lasts and how much RAM it consumes.

The menu also includes the "Background Process Limit" feature, which is the default "Standard Limit", but you can forcefully limit the number of background tasks, but artificially limiting background processes to 1-2 pieces can disrupt messengers and system notifications, so use this feature with caution, only for diagnostics.

⚠️ Warning: Do not disable processes with names that contain "System", "Android" or "Qualcomm" even if they consume a lot of memory.

Real-time monitoring allows you to capture the moment you surge memory, for example, if you open the camera, and you see what process dramatically increases consumption, it helps to identify the culprit of the brakes, which is not visible in the normal task manager.

Use of third-party analyzers and ADB

If built-in tools aren't enough, Google Play apps come to the rescue, programs like DevCheck, CPU-Z, or 3C Toolbox provide detailed statistics, and they can plot memory usage over time, allowing them to track leaks as the application gradually swells without freeing up the resources they're using.

For advanced users, the ADB (Android Debug Bridge) method is available to connect to a computer, which allows access to system logs without installing unnecessary applications on the phone. The adb shell dumpsys meminfo team gives a detailed report on the allocation of memory across all packets, the most accurate diagnostic method used by engineers.

adb shell dumpsys meminfo | grep -A 5 "Total PSS by process"

This command will filter out the output and show only a list of processes sorted by consumption, so you can see the exact values in kilobytes and megabytes for each component you run, which is especially useful when you need to find a hidden process that is not displayed in the interface.

Using third-party software requires attention to permissions. Many cleaners consume a lot of resources themselves. It is better to choose one high-quality analyzer than to keep five background boosters, which only exacerbate the problem of lack of RAM.

Google’s System Processes and Services: Who is to blame?

Often, the top of the consumer list is not the games you installed, but the system components. Google Play Services and Google Services Framework are an integral part of Android. They are responsible for synchronization, geolocation, notifications and store operation. On Xiaomi devices, their consumption may be higher due to constant background synchronization with the Mi Cloud.

Another frequent eater is the Media Scanner, which, after updating the system or downloading a large amount of photos, begins to index files, creating thumbnails, at which point it can take up a significant portion of the RAM and load the processor, usually a temporary phenomenon that lasts from 30 minutes to several hours.

System Server manages all the basic functions of the phone. If it consumes an abnormally large amount of memory (more than 1-1.5 GB for no apparent reason), this may indicate a driver conflict or damage to system files after a failed update, in which case a reset or firmware reflash helps.

You can’t shut down your system processes completely, but you can limit them, such as disabling synchronization of unused accounts or banning background activity for heavy applications reduces the burden on RAM. However, it is not recommended to completely get rid of Google services on global firmware versions to avoid unstable work.

💡

High memory consumption by system processes immediately after the upgrade is normal, and the system performs optimization, which will be completed in 1-2 days of active use.

The Impact of App Cache and “Heavy” Programs

Social networks and instant messengers are the main enemies of free memory on modern smartphones. Telegram, VK, Instagram and TikTok tend to accumulate huge amounts of cache. Images, videos, temporary files are all stored in RAM for quick access, but often not unloaded correctly.

Check through Settings → Applications → All apps let you see the cache size for each program. If you haven’t cleaned the messenger cache in a long time, it can take several gigabytes. Clearing the cache (not data!) is safe and frees up space, but doesn’t always immediately reduce your RAM consumption while the application is running.

Special attention should be paid to widgets and live wallpaper. Beautiful animated wallpaper on the desktop constantly keeps graphic buffers in mind. On devices with 4-6 GB of RAM, this can be a significant fraction.

⚠️ Note: When you clean these applications (not to be confused with cache), you will lose all correspondence, logins and settings within this application».

Regularly rebooting your smartphone (at least once a week) helps to completely clear RAM of the “junk” processes that hang in the background, which is more effective than any cleaners, which are themselves complementary processes.

Optimizing MIUI and HyperOS for memory savings

Xiaomi’s shells have built-in optimization mechanisms that can be customized. The Security app has an Advanced Cleanup feature that finds remnants of deleted apps and large files. Also useful is the Acceleration feature, which forcibly closes background processes.

In the battery settings, you can select No Limits or Hard Limits for each application. For instant messengers, you need to set No Limits to keep them running in the background, and for games and heavy applications that you rarely use, you can choose Hard Limits, which will prevent them from running in the background and consuming RAM.

Memory Extension, mentioned earlier, on fast memory devices UFS 3.1 works well, but on budget models with eMMC can cause lags. If you notice that after turning on this feature, the phone has become worse, turn it off. RAM It's always better than virtual.

It’s also worth disabling unnecessary system services like Getting Recommendations or Usage Analysis if they’re present in your firmware version. They collect telemetry and hang in the background, consuming precious megabytes.
