How to optimize the RAM memory of an Android smartphone to make it more fluid

Unless you have a high-end smartphone with largely comfortable features, you are not immune to slowdown problems on your Android smartphone. For those who do not have a war machine, it is always possible to do with the means on board and optimize the RAM memory to make their phone more fluid.


Some high-end smartphones now blithely exceed 8 GB of RAM. We think in particular of the Pixel 6 Pro, the OnePlus 9 Pro and the Samsung Galaxy S21 Ultra which each have 12 GB of RAM. And what about the Nubia Red Magic 6S Pro gaming smartphone powered by 16 GB of RAM? Users with such flagships thus have more than enough RAM to comfortably run the most demanding applications and the operating system.

In addition, they will be able to multitask and even launch games without fear of the occurrence of lag and slowness. However, the same cannot be said about smartphones with less RAM. Fortunately, it is quite possible to optimize for a smoother experience.

How to free up RAM on Android

We would have liked to have been able to increase the RAM of our smartphones as it is possible to do for storage space with a microSD card. Except that such models are still hypothetical, Google’s Ara project is notably dead in the bud. We can still cite the 5G Fairphone 4 smartphone, several parts of which can be replaced by the user when they are defective (battery, photo module, screen, speaker, USB port). However, it is not possible to improve its performance under the hood.

Interestingly, Xiaomi recently filed a patent for modular phone. Which would allow in particular to integrate faster components after purchase. Obviously, this concept could be confined to the patent stage. But it shows that the idea of ​​a phone that could be made more powerful a posteriori is still alive.

In the meantime, many of you still own smartphones with limited performance. And some flagships may also have fluidity issues despite their high-end technical data sheet. Especially if they are getting older. If you are in this case, we strongly recommend that you proceed to a sparing management of their resources. here are some tips for optimizing the RAM memory of an Android smartphone.

Check memory usage and close running apps

First of all, it is very important to know which apps are consuming the most memory resources on your Android device. Fortunately, the OS allows you to do this check, but also to force the shutdown of a running application. You must first activate the developer options.

  • In settings, go to the My Device section (also called About phone). Tap 7 times the version number. Developer mode is now enabled.
  • Then go to the Running services (the path may differ slightly depending on the versions of the OS and the overlay).
  • On Samsung, this section will be accessible directly from the settings. On Pixels and Huawei, you’ll find it in Settings> System. On Xiaomi, you will have to go to Additional Settings.

Running services

  • You have in front of you a list of running applications and the amount of RAM mobilized.
  • Tap an app and you can force stop no problem.

Disable or remove unnecessary apps and bloatware

While closing running apps frees up RAM, this approach is only temporary as apps tend to restart in the background. This allows you to deactivate or remove almost never used apps that consume your device’s RAM. To do this, nothing simpler :

  • Go to settings and then to the Applications section.
  • Click on Manage applications.
  • Click on the application you want to delete then on Uninstall.

Uninstall an Android app

  • To confirm, press OK.

In addition, the bloatware installed by default are sometimes as annoying as they are unnecessary. They also monopolize a good part of your RAM. By nature, they cannot be uninstalled completely. But it is still possible through roundabouts. One method is to root your smartphone before using the System App Uninstaller (ROOT) application, as explained in this tutorial.

Turn off animations and transitions

Certainly, the animations and transitions on Android make the operating system more modern and sleek. But they also put a strain on RAM. Ditto for the processor. When you have a limited smartphone, it is better to do without it. Here’s how to turn off animations and transitions on Android:

  • Activate the developer options (as explained above).
  • Then go to the Developer options section.
  • Scroll down to the settings for Scales.

Disable animation scales

  • Turn off all three scales by pressing it.

Do not use live wallpapers and heavy widgets

There are wallpaper apps on the Play Store to improve the aesthetics of your OS. Like animations, they are resource intensive and result in high RAM and battery consumption. The same is true for heavy widgets. If you are concerned about optimizing the RAM memory of your device, do not use widgets, or little. And avoid live wallpapers.

Use a RAM memory optimization utility

Whether or not to use apps that promise to optimize RAM or battery usage? Not everyone likes them for the simple reason that most tend to be counterproductive. However, there are some utilities that are effective in freeing up your device’s RAM. And ultimately get better performance.

This is the case of the RAM accelerator application. Once downloaded, all you have to do is open it and press the button. Fast optimization to optimize the use of your RAM.

Among the alternatives, let us quote in particular the applications Clean Master and CCleaner which you will also find on the Play Store.
