Full MIUI optimization on Xiaomi and Redmi phones in 2022

Nowadays, more and more different services are moving into electronic format. The number of different gadgets people have is also increasing. But no one teaches you how to use them thoroughly. People figure out all the devices themselves as best they can.

But such behavior can now be dangerous, due to the increasing incidence of fraud. If a person himself does not know what he can do with his device, and what will lead to other people having access to it, then it will be easy to deceive him into various tricks.

So you should always carefully study what you are installing on your computer or smartphone and what it can lead to.

How to optimize MIUI 12 on Xiaomi and Redmi

We have prepared detailed instructions, using which you will completely optimize your mobile device. The following procedures do not require root access or an unlocked bootloader. All actions can be quickly carried out in the phone settings.

Removing unnecessary applications

The first thing to do is remove useless applications . Xiaomi smartphones come pre-installed with many programs that are not needed for everyday use. Most of these applications are removed in the standard way, but some software can only be disabled or removed using additional software. Let's look at standard deletion:

Open “Settings” and go to the “Applications” section - “All applications” .
Click on the orange “Delete” and check the boxes of the programs that you want to get rid of. Then click on the blue “Delete” button. The number of free megabytes will also be displayed there.
We return to the previous menu and again go to the “All applications” tab. Now we carefully review the full list of installed programs, and open unnecessary applications one by one. If the software was not removed using the method described above, click "Close" and confirm the action. Before doing this, you can clear the cache. The application will now be disabled.

If you want to completely remove system applications, use separate instructions. You will need access to a PC and the Xiaomi ADB Fastboot Tools utility installed.

Disabling system advertising

The next step to speed up your Xiaomi phone is to get rid of built-in advertising . Due to the huge number of advertisements, the smartphone may freeze. Also, spam is annoying and interferes with the normal use of the device. Most of the advertising is concentrated in system applications, such as Explorer, Theme Store, Browser, Downloads, Music, Video.

To turn off advertisements, you need to go into each application in turn, open the settings and deactivate the slider next to the “Receive recommendations” line. You can also set a region with a minimum amount of advertising, for example, the UK. More detailed information is provided in this article.

Clearing storage

Optimizing system memory is also a must. You can clear your phone of unnecessary files using the pre-installed Security application.

Open the program and click “Cleaning” . Once the check is completed, the garbage size will be displayed (this includes data files, useless files, packages, data remains and memory). At the bottom, click on the red “Clear” button.
In the upper right corner, click on the gear icon and activate the cleaning reminder. We set the following parameters: garbage size - 100 MB, scan schedule - every day.
If your smartphone’s memory is overloaded, go to the “Deep cleaning” . Duplicate photos and videos are displayed here, as well as useless installation packages and large files. We remove unnecessary materials by checking them.
Go to “Settings” - “Applications” - “All applications”. Open each program in turn and click “Clear cache” .

Setting up autorun

Autorun, as the name suggests, allows applications to launch automatically after the smartphone is rebooted. Because of this, the phone takes longer to turn on and runs slower. Autorun does not affect the functionality itself: all notifications arrive on time, even if the application is not running in the background. Therefore, we recommend removing all programs from startup.

In “Settings” open the “Applications” item.
Go to the “Permissions” tab - “Autorun” .
Click on the three dots in the upper right corner and click “Show system applications”.
Turn off the sliders next to all autorun applications.

Checking background connections

Next, visit the “Data Transfer” section. Unnecessary applications may be connected to the network in the background, and this increases the amount of traffic consumed.

We look for the “Security” application on the desktop and open it.
Scroll down the page to the “Data transfer” item.
Open the “Traffic consumption” tab.
Go to the “System Applications” section and deactivate background connections for useless programs. You can safely disable connections in the background for applications such as «Analytics», «Mi Coin», "Activation service Xiaomi SIM», "Print spooler" And "System print service". If you don't use Facebook, turn it off as well. "Facebook Services" And "Facebook App Manager".
We return to the previous page and go to “Network Connections”. Here we prohibit access to mobile Internet or Wi-Fi for applications that we do not use.

Selecting your preferred network type

The preferred network type must be specified if coverage problems are observed. For example, 4G does not work well in your area, but your smartphone is constantly trying to connect to this network. Because of this, the battery drains quickly.

Open “SIM cards and mobile networks” and select a specific SIM card.
In the “Operator Network” section, look for the “Preferred network type” .
We set “3G Preferred”.

Turn off unnecessary Wi-Fi features

There are several options in the settings that actively discharge the smartphone. Therefore, they must be disabled.

Open the “Wi-Fi” item and go to “ Wi - Fi ” . We turn off two functions - “Select the best network automatically” and “Wi-Fi prioritization”.
We return to the main menu and go to “Connection and sharing” - “Print”. We disable the system print service if we do not use the printer from a smartphone. We also deactivate the “Mi Share” tool if it is not needed.

Restricting access to personal data

Another important procedure for fully optimizing MIUI 12. We need to open “Passwords and Security” - “Access to Personal Data”. Uncheck the following applications: Mi Video, msa, MiuiDaemon, Report and Xiaomi SIM Activation Service (optional).

Charge optimization

Now let's start optimizing the battery:

Go to the “Power and Performance” section.
Click on the gear in the upper right corner.
In the “Clear memory” , indicate “In 10 minutes.” This is the most optimal interval.
We go down to the point "Activity Control". If we rarely use some applications, we set it to “Hard Restriction”. In my case it's Duo, Google Play Movies and Google Photos. Please note that if the restriction is hard, the application may not work at all.

If your phone runs out of power quickly, we recommend activating the Energy Saver . What will it give:

System applications will be limited. Also, programs will not be able to run in the background.
Energy-consuming functions such as automatic synchronization, vibration response, turning on the smartphone when picked up, and the fingerprint icon on phones with an under-screen scanner will be disabled.
The memory will be cleared every time the mobile device is locked.

The “Ultra-energy saving” option should be enabled only in extreme cases when it is not possible to charge the smartphone. Because the restrictions are very strict.

Permission management

The “Location” resolution consumes battery power quite actively, so this parameter needs to be configured separately. To do this, go to “Privacy Protection” - “Location”. We check which applications have constant access to geolocations. By default, these are “Maps”, “Compass”, “Google” and “Mi Browser”. Instead of the “Allow in any mode” parameter, set it to “Allow only while using the application” .

Next, click on the three dots in the upper right corner. Select "Show system processes". Here you can deny access to the location for the MIUI Desktop and System Print Service programs. There is no need to change other applications, otherwise there is a risk of harming the operation of the smartphone.

Configure confidential settings

The Privacy section has many features that add advertising to the device. Let's look at which options need to be turned off:

Location history - for many users, this is a useless option that negatively affects battery life and allows Google to track your movements. We recommend disabling this feature to reduce spam.
— here we activate the line “Disable ad personalization”, and on the contrary, disable the “Keep a debug log for ads” item.
Use and diagnosis — deactivate this tool so that data is not automatically sent to Google servers.

Getting rid of unnecessary widgets

For your smartphone to work smoothly, you need to optimize your home screen. The desktop may slow down due to the widget ribbon. This element contains a huge number of information announcements, including advertising. To turn off the feed, you need to:

Go to “Settings” and open the “Desktop” item.
Deactivate the slider next to the line “Widget Ribbon” .
Confirm the action by clicking the blue “Disconnect” button.

Now go to the “Screen Lock” section. We set the sleep mode to turn on after one or two minutes of inactivity. To save battery as much as possible, turn off the “Wake up when picked up” and “Wake up to show notifications” .

Disabling automatic updates

Automatic updates sometimes start at the wrong time, so it's best to turn them off. Also, some system applications begin to malfunction after installing new versions.

In “Settings” we look for the item "Component Update". Click on the gear in the upper right corner, and in the “Automatic updates” line indicate “Do not update.”
Go to the Google Play application and click on the account icon. We go along the path “Settings” - “Connection settings”. Click “Auto-update applications” and set “Disable”.

Google Play also has a rather dubious function - Play Protection. The tool checks installed applications for viruses, which creates an additional burden. The fact is that viruses are extremely rare on Android devices, especially in programs. You can disable the option as follows:

Open the app store and click on the account icon.
Select the “Play protection” tab and click on the gear.
Move the toggle switch to the inactive state next to the inscription “Scan applications using Play Protection.” Confirm your choice.

Using the above instructions, you can set up any Xiaomi or Redmi phone quickly and efficiently.

Description of the Xiaomi proprietary application

MiDrive is classified as system software. The software is designed to organize easy access to the Mi cloud data storage. It can be integrated into Explorer to facilitate the use of cloud functionality. The purpose of the appearance is to replace the analogue of the same name from Google, because the companies are prevented from cooperating by the imposed sanctions.

The application is capable of fully managing all popular file formats in Xiaomi Cloud. The user can create, view, and delete any files without much difficulty. The program can be uninstalled, since its absence does not negatively affect the performance of the operating system, but it is preferable to simply block the operation using the privileges of the root account.

Why do you need built-in MIUI optimization?

Xiaomi smartphones have a system function that improves the performance of the mobile device. Let's briefly explain what MIUI optimization does:

clears RAM;
closes background processes;
reduces the load on the processor and graphics accelerator;
includes energy saving.

We recommend using this option on phones with poor performance. There is no need to activate built-in optimization if the device is equipped with a current mid-range or flagship processor. In a separate article, we talked about how to disable MIUI optimization.

How to unlink a device from Mi cloud

This manipulation will be useful if you do not use a smartphone connected to the cloud (you decided to sell, lost it, broke down, etc.). In this case:

Follow the link i.mi.com
Enter Mi Account details
Click “ Settings ”, here select our device and click “ Delete ”

Steps to reinstall or return removed malware

However, if you deleted any app by mistake, you can install it again or get it back on your phone by following these steps.

ads

Download the Xiaomi Virus File and then extract it using a ZIP extraction tool.
You will then see a file called "MIUI Bloatware File".
Then change the file extension from ".txt" to ".bat" and save it.
Copy the file and paste it exactly into the ADB and Fastboot (Platform Tools) folder.

This way, you can easily remove or uninstall bloatware (pre-installed apps) from your Xiaomi devices running on MIUI 10/11/12/12.5.

How to use Mi Drop technology

In order to exchange files via Xiaomi Mi Drop, you do not need to download anything. Everything is very simple:

Open the notification shade and enable the function by clicking on the Mi Drop icon (a circle with an arrow inside).
Open the file manager and find the file you want to send. Click on it and hold until the menu appears. Here select the “Send” option - Mi Drop.
This function must also be enabled on the smartphone that receives files. After the connection is made, a notification will pop up on the second phone, where you need to choose whether you want to download this file to your device or refuse to receive data.

Backup or “Backup”

“Backup” (Reservation) - creates a copy of the desktop, applications, wallpapers, alarm settings, MIUI settings and the system as a whole. Vital for saving personal data and transferring it to a new device.

How to enable backup

To enable backup:

Go to “Settings ”
Find the item “ Synchronization ”
Select “ Mi Cloud ”
Go to “ Reservation ” and enable “ Auto-reservation ”

Main functions of Mi Cloud

The menu is designed in an intuitive style, all icons are labeled:

Contacts - data from the phone book
Messages - incoming/outgoing SMS messages. In addition to viewing, we can also write an SMS and send it to the recipient
Gallery - photos and videos from the gallery
Notes—Notes from the built-in Notes app
Dictaphone recordings - Dictaphone recordings and recorded conversations
Find device—allows you to locate your smartphone on the map. In addition, here you see a few more points:

Briefly about the main thing

The short abbreviation encapsulates the long words - Software Development Kit (or set of developer programs). Many people think that any software development program can be called an SDK, that it is, for example, a Pascal or Delphi compiler. However, just as you can’t judge a book by its cover, you can’t judge a product by its name. An SDK is a set that expands the functionality of a program, game, or set of products; it makes it possible to create your own program, level or add-on, but only using the developments of the original one.

Annoying notifications

You are sitting, not touching anyone, and then the phone plays a notification sound and shows it on the screen. Do you think there's something useful in there? No matter how it is.

MIUI constantly bombards you with pop-up messages asking you to buy something, open something, or download something. They always promise you some surprises and gifts, send you emoticons and other dubious things.

When you explain to your wife where these “three unread messages from your lover” come from, you will probably be struck by the thought that you should have bought an iPhone.

Solution: Learn how to set up mobile notifications and turn off any you don't need. When you receive another “chain letter” from Xiaomi, do not swipe it to the right as usual. Swipe left and turn off the Show Notifications toggle to prevent the app from annoying you in the future.

Note: We recommend that you first disable individual bloatware on your Xiaomi device and then check whether the device is working properly or not. You should not start the removal process right away. Write down the name of the specific malware package from the list in a notepad before disabling or uninstalling it so that you can re-enable or reinstall it (if necessary).

DO NOT DELETE: com.miui.securitycenter | com.miui.securityadd | com.xiaomi.finddevice (Do not uninstall these three apps or services from your Xiaomi device. Otherwise, you may experience device lock or boot problems.)

Free cheese only in a mousetrap?

It happens that developers create a newsletter in which they inform everyone about the development of their tools and new versions. On the forum you can almost always find a thread with detailed documentation, which is constantly updated and supplemented. Add to this the articles by the SDK authors, their communication with ordinary community members and the round-the-clock work of technical support staff, and it immediately becomes clear that the community is not a community of free SDK testers, that this is an attempt to make the product better and of higher quality.

The proprietary shell of Xiaomi smartphones requires the presence of an application such as MIUI Daemon. Users have natural questions about what this program is and whether it is spyware. In our article you will find information about what functions the application performs and how you can remove it.

Three pillars of the SDK

An SDK most often consists of three main components. The most important thing is the program itself or a set of libraries that allows you to develop a new product based on an existing one.

The second part is documentation. Moreover, everything is described in it briefly, concisely and simply. It includes a Tutorial (a step-by-step tutorial in the style of "Creating the World in Six Easy Steps") and a Reference section, which provides a reference section on what can be done with the SDK.

The third piece of the puzzle is the most favorite among those who often use the product - ready-made examples. Moreover, they almost always cover all the features of the development kit. Thanks to their presence, you can often skip any Reference without trying to delve into the software environment. The samples quickly introduce the user to what can be created in the provided software package.

There are people who are too lazy to read even a short Tutorial. And this is not required! Take an example, edit it, adjust it to your criteria - and the new program component is ready.
