I have seen several people do something technically unusual. They repeatedly use the "Close all" function of the cell phone (or the "garbage can" button on the recent apps screen), " so that it is not slow " or to " save battery "..
This procedure closes all open applications on the phone, but what these people do not know (and they are not few) is that instead of speeding up the cell phone they are finishing it faster. Not only that. By closing the applications repeatedly, they are obtaining the opposite result to the desired one: slower and higher battery consumption. Crazy!
Managing applications on the cell phone
An application goes the following path when you launch or open it for the first time: Storage> Memory (RAM)> Processor. If you leave it (by tapping the start button or when switching to another app), it will return to the halfway point, which is RAM. Being in RAM, an application will be closer to the processor. Therefore, it will open faster when you run it in future times.
But if you close the application (remove it from recent apps from the multitasking button), the application will return to storage. When you reopen it, you are going to force the app to go down the road from the beginning. This means that the application will open slower. Not only because it is a longer "path", but also because storage processes data slower than RAM..
Closing everything increases battery consumption
Obviously the indicated error implies more work for the cell phone. The processor will have additional load and it will consume more battery. Imagine what it means for your cell phone to close all applications at once using the "Close all" button. You will multiply the battery consumption X times when you reopen all those applications.
Do not believe what I tell you. Test it. Open an app. Press the start button. Reopen the application and see how long it takes to open and display the information. Now close the application (from the multitasking button, bottom left, remove it by sliding to the side). Open it again and see how long it takes this time..
But I have many applications open!
This is a situation that you should only be concerned with on Windows. Here you must close the programs that you are not using, because if you have many open, the RAM will fill up. The computer will slow down and you will not be able to open a new program.
In Android this is not a problem because this system manages the RAM memory automatically. When memory reaches a certain limit, it removes older applications to keep your phone running smoothly and to make room for new applications to run.
When to close an application?
Sure enough, Android phones offer the option to close apps for some reason. The problem is not using it, but abusing it.
Closing an application is an excellent solution to refresh your information or when it does not work as it should. For example, if you are consuming a lot of battery . Although in this case it is better to uninstall it or look for an alternative.
Even the "Close All" option is recommended when the phone is very slow or something is not right. But if you do it repeatedly during the day, don't complain about poor battery life or slow apps to open. If the cell phone is always slow, consider real solutions .
