Android Marshmallow comes with a new memory management feature. If you’re one of the lucky early adopters who has the Marshmallow update, then you should take a few minutes to peek through this settings menu.
What is Memory Manager?
Memory manager is a new settings menu that describes how memory is used on your device. It gives you app-by-app breakdowns as well as total RAM usage, peak performance, etc.
Basically, it’s an at-a-glance overview of your phone’s memory usage for the past 3 to 24 hours. You can also see the percentage of memory currently in use and the amount of memory remaining.
You can find the new memory manager at Settings > Memory.
Using the Memory Manager
Open the memory manager by going to Settings > Memory. Then, tap the downward-facing arrow next to the “3 hours” icon to choose your desired time span.
I recommend choosing the 24 hours timeframe to give yourself the longest average time to analyze your data.
However, if you just recently ran a performance-intensive app that caused your device to lag, then you may want to select a shorter timeframe. You can choose from 3, 6, 12, or 24 hours.
Once you’ve chosen your timeframe, you can view app-by-app average memory usage. The worst RAM users will be at the top of the screen.
Want to get a closer look at each app’s memory usage? Just tap on each individual app to view its:
-Average memory usage
-Maximum memory usage
-Frequency (how often the app runs, based on percentage)
How to stop a Problematic App
You can also use this memory manager to stop a problematic app. If you notice your device is running slow, for example, then you may want to tap the three dots in the top right of the screen, then tap Force stop.
Most people will be happy to trust Android to use RAM in the best possible way – which means you probably won’t access this menu very often.
But if you’ve noticed performance slowdowns and other problems in recent weeks, then you can easily use this menu to identify the problematic app and prevent it from damaging performance further.
