How to view RAM on Xiaomi Mi A3

Owners of Android One smartphones often face the need to monitor system resources, and the Xiaomi Mi A3 model is no exception. Despite its clean interface, understanding how RAM is distributed is critical to keeping the device running in today’s applications. Many users are unaware that standard browsing methods can hide some of the technical information.

The amount of RAM available directly affects multitasking and switching speed between running programs. Unlike the MIUI shell, where the metrics are often prominent, in stock Android, you need to perform several additional actions. We will look at all the available ways to get accurate data about the state of your gadget's system.

Understanding the actual available capacity will help determine whether to close the background processes or look for the causes of sudden reboots. Often users confuse the physical amount of installed memory with what is available to the system after loading the kernel and drivers, the difference between these values can be several hundred megabytes, which is noticeable for the budget segment.

Technical characteristics of memory Mi A3

Xiaomi Mi A3 was introduced in two configurations, and the first step should always be to confirm exactly your modification. The global version is most often equipped with 4 GB of RAM type LPDDR4X, paired with the Qualcomm Snapdragon 665. However, in some markets there were options with 6 GB, which significantly changes the performance picture.

It's important to distinguish between physical volume and user-accessible resource. Part of the RAM is reserved by the system to run the Linux kernel, graphics accelerator and I/O buffers. So even if the box says 4GB, you'll see a number on the settings menu around 3.1-3.3GB, which is a perfectly normal behavior for the Android architecture.

Memory speed also plays a role, although it is fixed in this price segment. The LPDDR4X type provides sufficient bandwidth for everyday tasks, but when you start heavy games or process video, the buffer can become overflowing, and it is at these moments that the system begins aggressively unloading applications from the background processes.

Checking through standard Android settings

The easiest and safest way to find out the amount of RAM does not require installing additional software. In the pure version of Android, which is installed on the Mi A3, the information is hidden slightly deeper than in the custom shells, but it is quite real to find it.

You can select System, then you can find About Phone, and that's where the basic technical information is, but to see the detail from memory, you often have to click on the Android version multiple times in a row, activating the hidden developer menu if it's not already on.

After activating the developer mode (click 7 times on the build number), a new item will appear in the main settings menu. Going to System → For developers, you will find the Memory section. This shows not only the total volume, but also the average usage over the past 3, 6 or 24 hours.

Note that this menu doesn't update data instantly. If you've just rebooted your device, the statistics may not be complete. 15-20 minutes to collect correct data on resource consumption of running services.

Using the Engineering Menu for Diagnostics

For more in-depth analysis, which is not available in normal settings, there is an engineering menu, which is a special diagnostic interface built into the Xiaomi Mi A3 firmware, which allows you to see precise technical parameters, including memory frequency and busy addresses, which is useful when looking for hardware problems.

To get there, open the standard dialer phone and dial the combination ##4636##. If the code is entered correctly, the menu will open automatically, without having to press the call button. RAM.

⚠️ Warning: Be extremely careful in the engineering menu. Changing settings you are not sure about (for example, switching network types or resetting a radio module) can lead to loss of communication or unstable operation of the device.

Not all versions of the firmware on Mi A3 have activated access to the full engineering menu through USSD-If the code doesn't work, it doesn't mean the phone is malfunctioning.Manufacturers sometimes block that access on global versions of Android One for security reasons.

In some cases, an alternative way is to use ADB (Android Debug Bridge) via a computer, and by connecting the phone over USB and enabling debugging, you can enter the adb shell dumpsys meminfo command, which will give a detailed report on the allocation of memory for each process in real time.

Third-party applications for resource monitoring

If there is not enough built-in hardware, Google Play tools come to the rescue, and apps like CPU-Z, AIDA64, or DevCheck provide comprehensive hardware information that not only shows the size, but also the type of memory, the number of channels, and the current load as a percentage.

One of the advantages of these programs is the ability to view temperature and frequency in real time, which is especially true for the Mi A3, which can heat up when under intense load, which sometimes leads to trotting and slowing down memory, monitoring helps to identify “voracious” applications.

But remember, installing back-end services is a resource-consuming tool, and lightweight tools like Simple System Monitor are preferable to heavy combines, which take data from system logs without putting additional strain on the processor.

When choosing an application, pay attention to permissions. There are enough basic rights to read memory information, and requiring access to contacts or geolocation from such software should be alert, trust only trusted developers with a good reputation.

Analysis of memory usage in real time

It's not enough to know the total volume, it's important to understand how it's consumed. There's Running services in the developer section, which shows you a list of all the active processes and the amount of RAM they're eating right now, and that's the best way to find the brake culprit.

It often turns out that a significant portion of the resources are Google services or system sync processes. On the Xiaomi Mi A3 with its 4 GB of memory, every megabyte on the account, if you see a browser or social network occupying 500+ MB in the background, they should be optimized or limited.

There's also the concept of cached processes. Android tries to keep frequently used applications in memory so that they open instantly. It's not a memory leak, but a competent resource management. Forced cache cleaning often backfires, causing the system to waste energy restarting programs.

💡

If your phone is slowing down, don’t rush to put cleaners. Go to Settings → Apps and notifications → Show all apps, sort by size, and find heavy software that you don’t use.

Optimization and management of operational memory

Controlling RAM on pure Android is different from MIUI. There are no aggressive built-in cleaners that hang in the memory. Optimization comes down to fine-tuning the limits of background processes. You can find the background process limit item on the developer menu.

The default is the standard constraint. If you change it to "No background processes," the system will kill any application as soon as it folds. This will free up RAM, but it will kill multitasking: the navigator will recalculate the route and the music will interrupt. For the Mi A3, it is better to keep the standard values.

It's also worth checking the animation settings. Reducing the scale of window animation and transitions won't free up memory physically, but it will reduce the load on the graphics buffer, which will subjectively speed up the interface, which is especially noticeable on devices with low RAM.

⚠️ Warning: A persistent lack of free RAM (less than 200 MB in idle) may indicate a software failure or “memory leak” in a particular application that requires reinstallation.

💡

Regular memory monitoring helps to identify problematic applications, but do not fanatically clean RAM – Android itself effectively manages resources, leaving in memory often used data for performance.
