Random Access Memory (commonly known as RAM) is another important hardware feature that determines how smoothly your Android smartphone performs common operations.
It stores data and processes used by active applications and enables faster performance and multitasking. When your device is slow, apps keep crashing, or you plan to upgrade, checking RAM usage is essential to identify the problem.
Knowing how much RAM your phone has and how much is left is extremely important. In this tutorial, we will show you how to check RAM on your Android smartphone.
What is RAM & Why It Matters on Android?
Your Android device has a short-term working area, known as the RAM (Random Access Memory), where the data that is currently being used by the processor is stored, similar to a desk top that contains open files available with easy access.
RAM allows everything to load fast and without any delay when you move between apps, load games, and even watch videos. The more RAM, the more apps can be open in the background without reloading, i.e. the faster you can switch between tasks and the less disruptions you have.
Different Android skins have various approaches to RAM. To cite an example, Stock Android (as used on Google Pixels) has been reported to have leaner, more effective RAM management, keeping fewer background processes and less bloat, than heavier skins.
MIUI or One UI, on the other hand, can pre-load additional processes or have layers such as memory extension (swap-like virtual RAM) that aids in background multitasking but adds overhead.
How to Check RAM on Your Android Smartphone
It is possible to examine RAM of your Android smartphone in several ways depending on the model of the device and software version. This is how it can be done utilizing inbuilt features and trusted third-party applications.
Method 1: Using Android Settings (Universal Method)
Open Settings → Click “About phone”.
In some phones (such as Samsung), press Battery and device care > Memory to see the used and free RAM.
In other devices (such as Xiaomi or Realme), you can visit Additional Settings > Memory or under Storage.
Note: This design could be a little different according to your Android version. In Android 10 and 12, memory information may be under storage or hidden; in Android 13/14, it is often more convenient to find under device care or system tools.
Method 2: Using Developer Options
Open Settings → About phone.
Tap Build number 7 times to activate the Developer Mode.
Repeat the steps above and go back to Settings > System > Developer options > Running services or Memory.
In this case, you can see average usage of memory and actual RAM used by applications in real-time.
Method 3: Using Third-Party Apps
Reliable apps such as AIDA64, CPU-Z, and Device Info HW provide detailed RAM information, live graphs, and hardware dissection.
Advantages: Additional information, history of use, and diagnostics of the device.
Disclaimer: such applications might need access to the system data, make sure to download them only through the trusted sources (such as Google Play), and pay attention to the permissions required.
Tips to Free Up RAM and Improve Performance
These are the best tips to free-up RAM and improve Android performance:
Uninstall unused apps: Uninstall the apps that you do not use anymore. A lot of them run in the background and use RAM.
Background or behaving apps close: Navigate to use Settings > Apps > Force stop, or swipe them off in the Recent Apps screen. However, be not too greedy, Android does not need too much RAM and quitting applications you do not need is battery consuming as well as time-consuming on reopening.
Switch to Lite versions: Such applications as Facebook Lite or Instagram Lite occupy much less memory.
Use your phone’s built‑in optimizers: On Samsung, in Settings find the Battery and Device Care section then the Memory, tap Clean Now (or turn on Auto Optimization); the Security app on Xiaomi has Boost Speed; OnePlus has Battery and Performance, and then tap Ram Boost.
Expert tip: Third‑party RAM booster apps are a bad idea, they tend not to work, may cost you battery life, and may even slow your system down, as they induce reloading when it is not necessary. The in-built memory management of android is usually better.
When to Consider Upgrading Your Phone Based on RAM
Most of the modern apps, background functionality, and even simple multitasking can be a problem on your phone with 3GB of RAM or less. 6GB of RAM is now the gold standard in usability, supporting social media, browsing, and basic multitasking without issues.
But it is suggested that 12GB RAM or more is ideal when you are a gamer, a heavy multitasker, or you want your phone to serve several years. It offers smoother gameplay, less frequent reloads of apps, and it is more future-proof. In case you have a phone that constantly lags or closes apps there is a possibility that you need to upgrade depending on your RAM requirements.
Final Word
Learning how to check RAM on your Android smartphone is an easy but effective trick to learn how your device works. Monitoring RAM usage can provide useful information whether you are trying to determine the cause of slowdowns or whether you are planning a future upgrade. You can be informed through built-in settings, trusted apps, and so on. Monitoring your RAM can help you get the most out of it, multitask, and better understand when it is time to upgrade your phone.
