A significant amount of memory is reserved in mobile phones, which corresponds to the application cache, information that the operating system stores so that after reactivating the application it directly loads your cache to save time and energy at boot time. This affects both the working memory of the device and its memory. And it doesn’t hurt to know both types of caches.
There is usually some controversy about the cache memory in mobile phones: there are those who defend its abolition, especially when the memory and / or RAM memory is very fair; then there are those who defend that, since the cache improves the efficiency of the software, by eliminating it, the mobile ends up consuming more energy. In practice, both positions can be equally valid. However, in order to take action, you must first know the size of the cache.
How much cache have your mobile processes reserved?
Your Android runs constantly: In addition to the operating system itself, various internal processes help you to receive push notifications, have internet access for apps or make it easier for the surface to react to your finger touch. All this software reserves part of the cache both in the internal memory of the phone and in the RAM.
Android lets you know how much memory cache is reserved for each application and also provides information about the busy cache in RAM, the cache that the system uses to make multitasking as fast and efficient as possible. If you know this second type, you know which apps keep running even if you haven’t started them: this is an excellent way to monitor your phone. And to speed it up: Although your own Android takes care of adapting the running processes to your device’s RAM memory, you can always give it a little extra help if you notice a slowdown.
To find out which processes have a cache reserve on your Android phone, do the following:
Go to your smartphone’s settings, go to “Phone information” and enter “Android version”. The specific name may vary. Press Build Number 10 times. You have enabled developer options. Go back to Settings, go to “System” and enter the “Developer Options” you enabled with the previous process. Search for “Running Services”: Your Android will show you everything that is active on your phone. If you see an app giving you trouble, you can stop it right from there.
You can stop any process stored in RAM memory. And you also clear its cache
Now locate the top three menu items and select “Cached Processes”. Everything will appear to you as if it has reserved a place in RAM memory and it is not used in the foreground. If you want to clear the cache of any of these processes, click on it and then “Stop”: you close the app and clear its cache; This frees up space in your RAM memory.
Do not confuse the RAM cache with the cache occupied by the applications in the phone memory: the first is aimed at speeding up multitasking when switching between applications. The second collects the information downloaded by the apps during their operation. We recommend that you don’t clear the cache unless your phone is giving you trouble, but we encourage you to keep an eye on these processes in case an application is allocating too much memory for itself.
