How to enable or disable MIUI Optimization

There is no doubt that the Xiaomi layer is one of the most advanced options that exist in mobiles and in which we can make countless decisions about the operation of our mobile just by knowing the steps. Among these possibilities, one of the ones that makes the most changes to our terminal is the optimization of MIUI , an option designed for developers, but which we can take advantage of.

This new feature that was integrated with MIUI 12 has gained some popularity because of how quickly it can be put into operation and what it can achieve on Xiaomi smartphones. The large number of Chinese layer bugs led many to discover this utility to solve their problems. Although, on the contrary, other different errors may appear that we are going to explain to you.

What does this option do

As its name suggests, this MIUI tool is a possibility integrated into the mobiles of the Chinese firm to improve their performance. This tool will give us a series of variations when activated and will remove other possibilities with the intention of improving the power of the phone.

To be more clear about what the changes in this option consist of, we will first see what we will gain by having this Xiaomi customization layer software tool active. Although, later we will see if it is really worth having it enabled on our phones or not.

And what do we gain from it? In most Xiaomi mobiles, we will find this improvement within its ‘hidden’ settings. In this way, we will be able to enjoy a series of positive points:

  • Fewer errors when opening applications .
  • It will load slower apps but with less lag.
  • No notification issues.
  • Access to all the advanced options for the mobile.
  • Greater security and stability when connecting to Wi-Fi or mobile networks.

However, by having it enabled, we can suffer from different problems , such as the smartphone battery being consumed before it is due. Well, for its correct operation, it needs a good amount of energy.

How to activate it

We are facing one of those software tools that are hidden inside mobile phones. In this case, within the ‘secret’ settings of MIUI and its developer options. Therefore, we must follow a series of steps so that the terminal shows us the option to activate this software of the Chinese mobile personalization layer:

Activar optimización de MIUI

  1. Enter the Settings of your Xiaomi mobile .
  2. Then, scroll down to the Additional Settings section and enter this section.
  3. Then, go to the last option, the one that indicates ‘Developer options’. If it does not appear, you must enable this function from Settings> About the phone> repeatedly press on MIUI version until the developer options are enabled. In addition, your phone will tell you how many times it has left to activate.
  4. When they are activated, we will enter them and go down to the option where it says ‘ Activate MIUI optimization ‘.
  5. Finally, you just have to click on the switch to enable this function.

However, this functionality of the Xiaomi software layer is enabled by default on its smartphones. However, users have reported that after updating to version 12 of this layer they have lost this functionality, or it has been disabled by itself. Therefore, by following these steps, you will be able to see whether or not you have this function activated on your mobile.

What happens if you disable it

Before we can take the step to deactivate said system tool, we have to start by activating the developer options in Xiaomi if we have not done so before. This will give us a new access to the smartphone, regardless of whether it is a high-end or a budget smartphone with this layer of Chinese customization.

  1. To begin we enter the Settings.
  2. Later it reflected in ‘On the telephone’.
  3. We repeatedly touch on the section called MIUI version.
  4. Once the developer options activated message appears, we can continue.

Once this is completed, we will have to take the step to enter the developer options found in Settings> Additional settings> Developer options. Sliding to the end of all the options, we will come across this tool to activate or deactivate MIUI Optimization . We can also help ourselves with the search bar to locate the option instantly.

As we have seen, some changes do allow us to improve aspects of the system by simply deactivating this option, but others can lead us to encounter various errors depending on the version of MIUI we have, the security patch and also the smartphone. So that you don’t get any surprises, we explain and show you the errors that users have encountered and which have been recorded in the Xiaomi forums, as well as on social networks.

The mobile can get hotter

Heat is something that will never do your mobile phone any good and these types of tools have a lot to do with it. Some users have found that turning it off makes the processor tend to get hotter than it should.

Of course, it is not an exaggerated heat. That is, you will notice that the phone is a little above its usual temperature, but it is not that you cannot even touch it, that is, it should not cause any problem immediately. But, although it is not excessive, it is true that, in the long run, it could affect the components.

Why does it get hot when you disable it? Actually, this is because the system stops limiting processes and demands maximum performance from the processor at all times. It is as if you left it free to apply maximum power to operations that, perhaps, do not require as much.

Changes to system themes

Also when we deactivate this system option , the personalization section will be compromised. This is because the part that stores the themes is reset, which causes our smartphone to return to the original configuration on some phones.

If we don’t want to lose our customization of the system, icons, and backgrounds, it would be better not to deactivate the optimization, since it is a problem that we are not going to be able to solve in any other way than re-customizing the system with the themes.

Apps will ask for permissions again

The permissions that the apps request is a great security measure for our teams. However, when we work with this Xiaomi tool, they are one of the most affected by changing this option in the developer settings.

When we do it, what will happen is that we will be asked, again, for all the permissions in each of the apps that we use and stop working until we do it. This occurs because the system, as has already happened with themes, is reset, directly affecting permissions. Of course, it only affects the configuration, nothing puts at risk what you have stored in the internal memory, such as photos or videos.

Other minor issues

If we follow the steps that we have just indicated to deactivate the improvement of the system, the phone will suffer variations like those that we have explained to you previously, but they are not the only ones. Although they are the most important, there can also be some less problematic circumstances, but they can become a nuisance. For example:

  • Some notifications may not arrive.
  • You will not be able to use some advanced options.
  • Unexpected crashes in apps.
  • Home screen freezing.
  • Other possible system and application problems.

Is it better to turn it on or off?

Now that we know all the failures that it can cause and the points that we would earn, weighing everything that this could cause us, we realize that, on very few occasions, it will be better to deactivate the optimization of your Chinese mobile. Only in those cases in which we have a serious problem with MIUI and taking into account all the negative effects that the change could have on the system, would this option be recommended.

For all other users in a widespread way, MIUI improvement is the ideal option that we can have activated, applying general corrections in the whole system and solving in all smartphones problems that in the past have been general. In addition, considering that not all smartphones include this function, it would not be surprising that sooner or later the option disappears from Xiaomi, as has already happened with previous adjustments that ended up harming rather than solving errors.

Because it does not show up?

It is possible that in some Xiaomi mobiles, especially the smartphones of the firm’s submarines, they do not have this tool available, since it is due to a limitation of the customization layer. It shouldn’t, but think that, for example, POCO mobiles have a different launcher.

In order to prevent users from modifying it, the tool is removed on some devices with this software layer, however, it could also be due to the system version. More than anything, because there have been many users who have reported that with the passing of updates this setting has disappeared from their phones.

Although, with the arrival of the update to MIUI 12.5 and MIUI 13, this option has been seen by more models so that we can use it according to our needs.
