The previous Android OS version the Android Lollipop is designed such that users can check the RAM status of their phone and the memory used by each of the apps. This feature still plays a big role and many users doing intensive multi-tasking need to monitor as to how much memory is gulped by some of their heavier apps. The latest Android M aims to improve this functionality by proving a more comprehensive way in order to check the average and the maximum RAM that each app can occupy.
However, in order to access the Memory section in Android M what it seems in the recent M Developer Review is that you need to navigate to Systems > Apps and then touch the three-dot menu at the upper right corner after that open Advanced and tap on Memory.
After accessing this and getting inside, users would be getting information about the per-app breakdown of the average and maximum RAM used by each of their apps, both pre-installed (system) and user installed. The dark green shade shows the average reading while the lighter green shade would show the absolute amount of operational memory occupied by the app. Users can even see that the app in question is rarely running or constantly running in the background. Tapping on the app would reveal all of its running process along with the amount of RAM they occupy. The apps that are trivial can be stopped by tapping of the “X” button to the right. The “Force Stop” button will allow you kill all the misbehaving apps.
Thus these changes coming from Android M we surely optimize the RAM usage to a great extent. Check the images below to get the idea.
