Xiaomi developers are constantly improving their proprietary firmware, thanks to which the shell boasts stable operation, interesting features, and a minimum of bugs. But some options, such as built-in optimization, are controversial and sometimes interfere with the user. Therefore, many people want to know how to disable MIUI optimization on Xiaomi phones and whether it is possible to do this on new firmware versions.
What is MIUI optimization, and what is it for?
MIUI optimization is a system tool that simultaneously performs many small tasks to improve the phone. Namely:
- automatically freeing up RAM;
- reducing CPU load during multitasking or using demanding programs;
- limiting background processes;
- turning on the power-saving mode when the battery is low;
- running some applications in parallel, so the processor is less stressed.
As we can see, the feature with the same name is responsible for optimizing the firmware and speeding up Xiaomi. The tool allows you to maintain a balance and not overload the mobile device. All this happens in automatic mode: the user does not need to clear RAM or disable unnecessary background processes.
Despite the aforementioned advantages, optimization can also harm the smartphone. The fact is thatMIUI algorithms interfere with the operation of the operating system and sometimes block certain actions that the user wants to do with his device. For example, the optimization does not allow full use of the popular application YouTube Vanced. Other third-party programs may also not work correctly.
Now you know why you need optimization. Below we’ll look at the pros and cons of this feature so you can decide if you want to turn off MIUI optimization.
Pros
The advantages are not very many, but they positively affect the phone’s performance.
- Acceleration of the smartphone.
- Charge control and increased battery life.
- Correct functioning of system applications.
- Stable and frequent updates.
Cons
Not without disadvantages. Especially MIUI optimization will not appeal to experienced users who want to experiment with their phones.
- Possible conflict between third-party applications.
- Some programs do not install.
- Issues with animations and music player.
- Forced closing of necessary background processes.
- Poor quality of screenshots if you take them with buttons.
- Limitation of Always On Display.
Optimization will be useful on phones with weak hardware. If you have a mid-range or flagship smartphone, there is little point in using this feature.
How to turn off optimization on Xiaomi with MIUI 13
Before turning off optimization on MIUI 12, read the list of possible consequences:
- Permissions for all apps will drop. Access to the requested information will need re-issued when launching the app.
- Cookies will disappear from your browser.
- The color of the status bar will turn gray.
- Some users have noted that “over the air” updates arrive less frequently or there are no updates. But these are isolated cases.
Step 1: Return the item to the settings
MIUI optimization is not displayed in the settings on the latest firmware versions. Such an item is simply missing, making it impossible for the user to deactivate the option. But it’s quite realistic to get the tool back. There are two ways: using the phone or PC.
Via smartphone
First, you need to activate the developer mode. It’s disabled. It will not be possible to enter the section with advanced parameters.
- In “Settings” open the item “About the phone” and 5 times quickly click on the line ” MIUI version “. You will be notified that you have become a developer.
- Go back to the original menu and go to “Advanced Settings” – “For Developers”.
- Scroll down to Restore Defaults. Click 4 or 5 times. After that, the line “Enable MIUI optimization” should appear at the bottom.
Interesting information! The line “Restore defaults” can be activated even if it is grayed out. To do this:
- Go to “Advanced Settings” – “Language and input”.
- In the “Autocomplete” tab, select “Google”. Confirm the selection.
Using a computer
If you can’t return an item through your phone, you’ll need access to a computer. The procedure is more complicated and time-consuming.
The method will only work on smartphones where the “Restore Defaults” line is inactive (grayed out). If the section is clickable, the PowerShell operation will cause an error. So first, go to the phone settings and try to disable optimization from there.
- Turn on USB debugging.
- Install adb drivers on the computer.
- Connect the smartphone to the PC with the original cable. Allow USB debugging.
- Go to the folder and, holding the “Shift” key on your keyboard, click on the free space with the right mouse button.
- Select “Open a PowerShell window here”.
- Type the command .adb devices. The serial number of the device should come up.
- Then type .adb shell settings and put secure miui_optimization 0 if you want to disable it. In contrast, putting secure miui_optimization 1 will enable MIUI optimization.
- Disconnect your mobile device from your PC and reboot. Done.
Step 2: Disable Optimization
To deactivate, move the slider to the inactive state. A warning will appear that doing this may harm the phone, and some data will not display correctly. If you are sure of your choice, click “Accept”. The factory optimization will then be disabled.
FAQ
Will phone performance deteriorate after disabling optimization?
You will not notice any particular difference, especially if the iron of the smartphone is up to date. Autonomy will not change much, either.
What to do if the item “MIUI optimization” disappears after each entry to the settings?
Every time you’ll have to click on the line “Restore defaults repeatedly.”
Should I turn off optimization before getting root rights?
Yes, it is advisable to turn off optimization, so there is no conflict of components. Turning it off is recommended before unlocking the bootloader or installing new firmware.
