How to Check App Memory Usage Android?

how to check how much memory an application is consuming

Apart from the processor and the brand, we compare two main numbers when buying a new smartphone. The more the storage size and RAM installed figures are, the dearer a device would typically cost. Modern apps are becoming more disk and memory consuming. If you happen to own a Xiaomi smartphone, MIUI 12, based on Android 10, can eat up to 3 gigabytes of RAM.

If you are short on any of the memory types, the device can start working sufficiently slower. While purchasing a device with 12 GB of RAM installed is not yet mandatory, having some three or even six gigabytes can be a good idea. Should you have less than that, it might be useful to learn management tricks. Let’s have a look at how to do that on your Android device.

How much space on disk does it take?

Having free disk space is as crucial as available rapid memory. If your device is working slower and asks to free some space when you try to download something, it is the high time to have a look at disk offenders. To do that, simply:

1. Go to the main Settings by pressing the gear icon from your home screen, drawer, or notification shade.

2. Tap storage.


3. Choose Apps in the list of a data type.

This will let you see all the apps installed on your drive and tell how much space they occupy. Feel free to install a disk analyzer app from the Play Store. Keep in mind, though, that most Android devices have something like this preinstalled by the manufacturer.

Using third-party apps to check available RAM

If you wish to make sure you have enough memory available, feel free to download one of the dedicated apps. To do that, simply:

1. Go to the Play Store.

2. Type CPU-Z in the search field or simply follow this link.

3. Install the application.

4. Launch it from the home screen or app drawer.

program cpu-z

5. Сhoose the Device tab, which is currently the second from the left.

Look for Total and Available RAM fields to learn the numbers you are looking for. Keep in mind, though, that information displayed can be not 100% accurate. Feel free to use any similar piece of software to compare the results.

Approximate number in Recent apps

Xiaomi fan base increases every year. If you are an MIUI user, there is a simple way to check both total and available RAM. Press the cube icon typically located on the left-hand side on the bottom of the display. You will see the information you need in the top right corner. If there is nothing there, follow these steps:

  • long press anywhere on the home screen,
  • tap the cog icon in your right bottom corner,
  • choose More,
  • scroll down to enable Display memory state slider.

If you use gestures, swipe from the bottom of the home screen and hold the finger for a second to see the recently launched apps and the numbers you need.

Unload all the apps, remember the memory number and launch the program you wish to check the RAM usage. The difference between available memory before and after you do that will give you an approximate figure.

Check exact RAM usage

If you are a stock Android user with a modern device, the only way to check the information is to become a developer. Follow these steps:

1 Open main settings.

2. Tap About the device menu item.

3. Hit build number multiple times until you see the message that you have become a developer.

4. Go to Developer options and tap Memory.

5. Choose memory used by apps to see all applications and RAM consumed by each of them.

The items will be listed by the usage. You can look through and disable or uninstall some of them. Focus only on the ones you have downloaded yourself. You can as well unload all the active RAM consuming applications by swiping them off on the recent apps panel. Keep in mind, though, that closing and reopening the programs can negatively impact battery life.

RAM and disk space available are two core components responsible for seamless user experience apart from the processor and GPU. Before buying a new device, consider these two figures. While having more than enough will not harm, smartphones with vast memory will cost dearer. It is worth choosing a figure between three and six or even eight for optimal performance. Keep in mind that this number can increase as time goes by. If you are using a device with two gigabytes of RAM or less, you will probably need to manage the memory usage quite often. Thankfully, you have all the tools available inside Android.
