Why you should never install an optimizer

The above apps are the best Android cleaners you can download to your mobile right now, but are they really necessary? Subsequently, let's find out the keys for which the installation of an optimizer in the terminal is not recommended.

Find out how RAM works

Most of the GB of RAM will always be occupied.

Before installing RAM cleaner apps like crazy, have you ever thought about how it works? There RAM, as the name suggests -Random Access Memory- is a temporary memory to which the system has access at all times. It is a working memory where information relating to all the processes that the phone has to manage is loaded.

If you open WhatsApp, the data will be sent to RAM and in a subsequent opening of the app, since the process is already loaded, it will open much faster.

Applications need to run in the background as well, that you here believe or not, this does not kill the battery or something like that, as the system knows very well how to handle RAM.

A separate case is that the application has zero optimization, in which case the system itself cannot manage resources properly it requires, and this is where the problems arise.

Android follows the maxim "RAM unused, RAM wasted". Whether you have 2, 3, or 8GB of RAM, more than half of these gigs will always be busy. Android deploys processes to keep as much information as possible in RAM, as this is the best way to manage terminal performance.

The problem is that Android is free and developers can ruin it by creating applications that are too resource-intensive. Applications such as, for example, Facebook, they require resources very more than they should.

By demanding so much from the system, it has to allocate much of its RAM to processes like Facebook, and take priority off others who should be active, but which are closed so that the app can remain open.

These inconsistencies are what create problems, but the way to fix them is not to install a cleaner. You will understand this very easily, when you understand how a cleaner works and what its real purpose is.

How optimizers work

Optimizers only get a temporary improvement in mobile performance.

Cleaners are basically for cleaning… For earn money. Filled with advertising, sending information to Chinese servers to earn money (not all, but most), while consuming more resources than they promise to save. Anyway. These applications have some basic functions:

  • Clear your mobile cache (the only thing they do right, and something you can do yourself from the settings)
  • Clean large files (they also do it well, and you can too)
  • Clean RAM (severe problem)
  • Add a boost to your cellphone (God knows what to make it go faster)
  • Check your cell phone battery (they spend more than they save)

The argument is easy, Cleaner, like Clean Master, delete all applications via one "Closing force", not only remove them from multitasking.

This has an immediate consequence, applications are reopened to occupy their RAM memory space, with the consequent CPU and RAM consumption.

"The thrust they promise" is none other than the temporary increase in performance which can give a low-end phone to shut down processes. However, after a few minutes, everything will return to its normal course, so it makes little sense. So, in case you want to install a memory optimizer on your mobile, Google Files is the best app to clean your phone, among other things because it "does not touch" or the RAM and GPU of the mobile phone, but rather limits itself to remove those files that you don't use and that consume space on your mobile. Not to mention that offers all the guarantees of a giant like Google.

What to do to optimize your mobile

Optimizing your mobile doesn't mean using third-party applications, but because you you take care of it.

Do not install badly optimized applications like Facebook, take care of cleaning the cache once a month, close large games or applications which will no longer run in the background later.

This way you will save battery, you will increase the performance of your mobile and you won't have any problems whatsoever, beyond the hardware limitations of your mobile.
