The speed of your smartphone and the ability to run several applications at the same time directly depend on the volume RAM. Often, users encounter lags or sudden reboots of apps, not realizing that the device has simply exhausted the available resources. Understanding how many gigabytes are available to the system is the first step towards proper operation of the device and identifying the reasons for its slow operation.
Manufacturers often indicate maximum characteristics in advertising booklets, but the actual figure available to the user may differ due to system reserves or firmware features. There are many ways to get accurate information, from built-in menus to professional engineering codes. In this article, we will analyze all verification methods, from the simplest to the most advanced, so that you can accurately assess the potential of your gadget.
Checking through standard system settings
The most obvious and safe way to find out the volume RAM is to use the built-in interface of the operating system. However, the path to this information can vary significantly depending on the manufacturer's shell. On “clean” Android or smartphones with an interface close to stock, the data is usually hidden in the “About phone” section.
You need to go to the menu Settings → About phone → Device characteristics. The total amount of memory is often indicated here, but the current load is not always displayed. Some shells, such as MIUI ot Xiaomi or One UI ot Samsungoutput this information more explicitly. For example, in the battery or device maintenance settings, you can see detailed statistics on resource usage in real time.
It is worth noting that the standard menu often shows only the total volume, ignoring how much memory is occupied right now. This is sufficient for a superficial check of the specifications upon purchase, but a more in-depth analysis will be required to diagnose performance problems. If there is no “Memory” item in the settings menu, it means that the manufacturer has hidden this option to simplify the interface.
⚠️ Attention: The settings menu interface may change after major operating system updates. If you do not find the item you need, try using the search inside the settings by entering the word “Memory” or “RAM”.
Using the engineering menu and secret codes
For more technically savvy users there is access to hidden sections of the system through special engineering codes. This method allows you to access service information that is not displayed in the regular interface. Entering a combination of characters into the dialing field activates a hidden hardware testing menu.
The most universal code for testing memory is ##4636##. After entering this combination (there is no need to press the call button), the “Check” menu will open. Select item Memory information or Memory Info. Here you will see not only the total volume, but also a detailed breakdown by process: how much the system takes up, how much is free and how much is used by the cache.
However, this method does not work on all devices. Many modern manufacturers, such as Huawei or new models Samsung, block access to the engineering menu for security reasons or to prevent the user from accidentally changing settings. If the code does not work, do not panic - this is normal practice for modern firmware.
Third-party diagnostic applications
When the built-in tools are not enough, specialized utilities from the store come to the rescue. Google Play. These applications provide comprehensive information about the hardware of your smartphone, including memory type, frequency and current load. One of the most popular and reliable tools is CPU-Z.
After installing the application, go to the Device or Memorytab. Here you will see a parameter Total RAMthat shows the physical amount of installed memory. A parameter Thresholdis also displayed, indicating the limit after which the system will begin to forcefully close background applications. This is critical information for understanding why your phone is lagging when opening heavy games. Another great option is an app that provides a detailed report in the style of a computer diagnostic utility. It will show not only the volume, but also the temperature of the components, which is useful for a comprehensive assessment of the condition of the device. Using such apps is safe and does not require superuser rights (
Another great option is the app AIDA64, which provides a detailed report in the style of computer diagnostic utilities. It will show not only the volume, but also the temperature of the components, which is useful for a comprehensive assessment of the condition of the device. Using such apps is safe and does not require superuser rights (Root).

Analysis through developer mode
In the operating system Android there is a hidden section for developers, which provides access to advanced debugging and monitoring tools. Activating this mode allows you to see processes that are usually hidden from the eyes of the average user, and understand exactly how it is distributed. RAM.
To activate the mode, go to Settings → About phone and quickly click 7 times on the item Build number. After the message “You have become a developer” appears, a new section will appear in the main settings menu For developers. Inside, find the item Running services or Running Services.
This section displays a list of all active applications and services indicating how many megabytes each of This is the best way to find the “culprit” of a memory leak. If you see an application that consumes a disproportionate amount of resources in the background, you should force it to stop or delete it.
| Parameter | Description | Normal value |
|---|---|---|
Total |
Total physical amount of RAM | 4 GB, 6 GB, 8 GB and above |
Available |
Free memory right now | 1.5 – 3 GB (depending on the model) |
Used |
Occupied by the system and applications | 50-70% of the total volume |
Cache |
Temporary data for acceleration | Can take up to 1 GB |
⚠️ Attention: Do not disable system services in the “Running Services” menu if you are not sure of their purpose. Forcibly stopping critical processes can lead to a reboot of the phone or unstable communication.
The difference between physical and virtual memory
In recent years, marketers have been actively promote memory expansion technology, calling it Virtual RAM, RAM Plus or Memory Extension. Users often confuse physical RAM soldered on the board with a virtual partition created using space on the internal storage. It is important to understand the difference so as not to overestimate the capabilities of a budget smartphone.
Physical memory (LPDDR4X, LPDDR5) operates at very high speeds and is essential for instant system response. Virtual memory uses slow flash drive (eMMC or UFS) Although this helps keep more apps in the background, the speed of their deployment will be much slower than using real RAM.
In the settings of many modern smartphones (for example, Samsung Galaxy A series or Xiaomi Redmi), you can manually adjust the amount of allocated virtual memory. However, increasing this parameter does not always improve performance; on the contrary, when actively working with heavy tasks, constant writing to the drive can even slow down the device and shorten its service life.
How. interpret the received data
Having received the coveted numbers, many users ask the question: “Is this normal?”. The answer depends on your tasks. For basic use (messengers, browser, YouTube), physical memory is quite enough. If you have less than this amount, the system will constantly unload applications from the background. 4. GB physical memory. If you have less than this amount, the system will constantly unload applications from the background.
For comfortable multitasking and modern games, the optimal volume is from 6 GB to 8 GB. In this case, you can switch between heavy applications without completely rebooting them. Flagship models with 12 GB and more are aimed at enthusiasts who keep dozens of tabs open and use them. resource-intensive software.
If you notice that the available memory is constantly low (less than 500 MB) even after a reboot, this is a signal to act. Perhaps some application has a “memory leak” or a lot of garbage has accumulated on the system. In this case, it is worth revising the installed software and clearing the cache.
- 🐢 Less than 3 GB: Budget level. Suitable only for light tasks, games will crash.
- 🚗 4-6 GB: The golden mean. Comfortable work in social networks and navigation.
- 🚀 8 GB and higher: High performance. Reserve for the future and heavy games.
⚠️ Attention: The memory characteristics indicated in the box or on the store website may not coincide 100% with reality due to rounding by the manufacturer. The system may show 3.7 GB instead of the declared 4 GB - this is a technical norm, not a defect.
Frequently asked questions (FAQ)
Why does the settings show less memory than stated in the specifications?
Part of the RAM is reserved by the system kernel and hardware drivers (video card, modem) immediately when you turn on the phone. This area is not available for user applications, so the actual available volume is always slightly less than the physical one.
Is it possible to increase the physical RAM on the phone?
No, the memory chips are soldered on the motherboard and cannot be replaced or upgraded at home. You can only increase virtual memory using the internal storage, if such a function is provided by the manufacturer.
Does the fullness of the internal memory affect the operation of the RAM?
Indirectly, yes. If the internal drive is full, the system has no place to create page files and cache, which can slow down the entire device, creating the illusion of a lack of RAM.
How to find the type of memory installed (LPDDR4 or LPDDR5)?
Standard Android settings do not show the type of memory. To obtain this information, you need to use applications like CPU-Z or AIDA64, which read data directly from the memory controller.
