In Windows, if you want to see how much memory a program is using, checking it is as easy as opening the Task Manager. In Android, the system does not work exactly the same, but you can also see the memory use of the applications, although it is a bit more hidden.
How to know which apps use more RAM on an Android mobile 2021
If your mobile does not have much RAM and you want to identify those applications that consume the most memory, you can consult the data from the options for Android developers.
1. Activate developer options
Formerly, some layers and Android ROMs showed you the memory usage directly in the recent view, although today it is more rare to find the data. However, there is still an infallible way to see memory use and that should be available on almost all Android phones: from the developer options.

Therefore, before you can use the memory of the different applications, you must activate the Android developer options, if you have not activated them before. The way to do this has been the same for years: go to the System section of the settings, enter Phone information and quickly tap on Compilation number seven times.

Once this is done, you will see a notice indicating that the developer options have been activated. You will find them as a new menu that was not previously in the System section of the settings, although some layers include it as a separate menu. If you can’t find them, use the settings finder at the top.
2. Check memory usage
With the developer options active, the next step is to enter these options, which are generally found in the System section. Then touch on Memory, which in most cases is the first option shown, at the top.

Once this is done, you will see the general status of the mobile’s RAM, including current and average use. If you want to see the usage for each application, you need to enter Memory used by applications.
Now, you can see the average use of RAM for each application, including the system. Android gives you the option of viewing memory usage data in different time ranges: 3 hours, 6 hours, 12 hours or 1 day.
By default, Android sorts the list of applications by average use, albeit with the menu? at the top you can change so that they are ordered by maximum memory use and not the average. In this way, you will be able to identify the apps that occupy the majority of your mobile’s RAM in specific cases (such as when you are using them intensively).
