Buying a new Xiaomi smartphone is always the start of an exciting but sometimes confusing initial configuration process. Immediately after unpacking, the user is faced with a lot of system offers, requests for account installation and intrusive recommendations that can confuse even an experienced owner of equipment. Proper initial configuration of a device based on MIUI or HyperOS is critical, because this is the stage where the foundation of stability, autonomy and security of the entire system in the future is laid.
Many ignore subtle privacy settings or skip screen calibration steps, relying on factory installations that aren’t always perfect for real use. Deep customization allows you to turn a standard gadget into a unique tool that fully meets your habits and needs. In this guide, we will examine in detail every step from activation. SIM-maps to covert optimization of background processes so you get the most out of your device.
Special attention should be paid to creating and binding Mi Account, as it is the key to the ecosystem, cloud storage and the function of finding the device in the event of loss. Without a proper configuration of this element, many smartphone features will remain blocked or will not work correctly. Next, we will move on to eliminating system “garbage” and advertising that are included in the shell by default, which will significantly improve the user experience.
Primary activation and basic system configuration
The initial launch process starts immediately after the power is turned on, when the system suggests choosing a language and region. It is important to carefully consider the choice of region, as this depends on the set of pre-installed applications and the availability of certain system functions, such as themes or specific widgets. After selecting a language, the system will offer to connect to the Wi-Fi network, which is a prerequisite for activating most services of Google and Xiaomi.
In the lock screen and biometrics settings phase, the system strongly recommends creating a pin or pattern lock. Biometric data such as a fingerprint or a face scanner should be configured in good lighting and in different angles for maximum unlock accuracy. Don't skip this step relying on a password alone, as biometrics greatly speeds up access to banking applications and secure folders.
The next step is to sign in to your Google account and Mi Account. Contacts, calendars, and notes are synced at that point, so make sure you're using a stable Internet connection. If you're switching from another Android smartphone, the system will suggest moving data over a cable or cloud, saving hours of manual app installation.
After you have completed the master setup, take your time to install third-party launchers or heavy games. Give the system 15-20 minutes to index files and optimize application databases. During this period, the device may warm slightly, which is absolutely normal behavior for the processor during intensive work.
Advertising removal and privacy optimization
One of the first things to do after activation is to turn off system advertising. In MIUI and HyperOS shells, the ad modules are built deep into the system and regulated by the MSA (MIUI System Ads) service, disabling this service is the first step to a clean interface without pop-ups in standard applications.
To deaktivate the ad, go to Settings → Passwords & Security → Access to Personal Data. Find the msa and turn off the switch. The system will try to dissuade you by running a countdown of 10 seconds, then click on the shutdown again. Sometimes this procedure has to be repeated 2-3 times, since the server may not respond the first time.
⚠️ Note: After disabling the msa service, banner ads in system applications may disappear within 24 hours, rather than instantly.
Next, you need to go through the built-in apps and turn off recommendations in each of them. In the Security app, click on the gear and remove the tick from "Receive recommendations." Similar actions are required in the Music, Video, Explorer and Downloads applications, which will remove intrusive news feeds from the interface.
💡
For quick navigation on settings, use the search at the top of the Settings menu by entering keywords like “advertising” or “access”.
In the privacy section, you should restrict applications from accessing your location data. Many programs request geo-location without real need, which not only violates privacy, but also consumes battery power. Go through the permission list and set "Only when using the application" for all services except navigators and taxis.
Setting up the screen, interface and navigation
The screen is the main element of interaction, and its correct calibration significantly affects comfort. In the Settings menu → The screen is recommended to immediately select the appropriate refresh rate. For models with support for 120 Hz or 144 Hz, it is better to leave the default or Maximum mode, so that the interface feels as smooth as possible.
Color rendering is also customizable. Saturated mode makes colors bright and flashy, which many people like when watching media, but distorts real shades. For photo or document reading, you better switch to Standard or Professional mode, where you can manually adjust the color temperature in Kelvins.
Navigation in modern Xiaomi smartphones uses gestures by default, but many users prefer the classic three buttons. You can change this in the Settings → Additional settings → System navigation. Here you can also customize the hidden area (" bangs"), which allows you to visually mask the cutout under the camera with a black bar interface.
| Parameter | Recommendation | Impact on the system |
|---|---|---|
| Frequency of update | Maximum (120 Hz+) | Smooth animations, increased battery consumption |
| Reading mode | Insert on schedule | Reduced load on the eyes, warm shade |
| Dark subject matter | Automatically (at sunset) | Energy savings on AMOLED, comfort at night |
| Type size | Standard or Medium | Screen capacity, text readability |
Remember to activate Adaptive Brightness, which learns your preferences and automatically adjusts the backlight depending on the lighting, which is not only convenient, but also helps save energy in the dark.
☑️ Checking screen settings
Battery and background process management
The Android Aggregate Optimization in conjunction with Xiaomi’s shell creates an aggressive background management system, which prolongs battery life, on the one hand, and can prevent notifications from coming from instant messengers in a timely manner, so that important messages are not lost, you need to manually adjust the behavior of key applications.
Go to Settings → Applications → All apps, select the right messenger (such as Telegram or WhatsApp) and go to the section "Battery Savings." Set the value No restrictions. This will prevent the system from "sleeping" the application when it is not in use, providing instant delivery of messages.
⚠️ Note: Setting “No Limits” mode for dozens of applications can lead to a noticeable decrease in device autonomy in one day.
For a general battery diagnosis, use the built-in Safety app, which allows you to see flow statistics and identify parasitic programs, and it is also useful to activate Adaptive Charging (if available in your model), which slows the battery filling process after 80% at night, to extend the life of the cell's chemistry.
In the Battery section, you can configure scenarios, for example, Battery mode (or Savings) limits background activity and synchronization, which is useful at the end of the working day, while Performance mode keeps the processor at high frequencies, which is necessary for gaming, but not necessary for social networks.
Working with memory and file system
Modern Xiaomi smartphones use a file system that requires proper maintenance to maintain high write and read speeds. Periodic cache cleaning and deletion of residual files is a mandatory procedure. The Security app has a "Cleanup" tool that automatically finds garbage, but its operation can be adjusted more finely.
It's important to set up the right microSD card if your model supports installation, and the system will suggest using the card as an internal storage device or as a portable storage device, and the choice of the internal storage format will encrypt the card, and it will only work with this phone, but will allow you to install applications on it.
To manage files, use the standard Explorer, which can sort files by type and clear duplicates. Regularly check the DCIM/.thumbnails folder, where gigabytes of thumbnails of photos can accumulate, and the Android/data folder, where game and instant messenger caches are stored.

Remember the Extension feature available in newer models. It uses a portion of the permanent storage as RAM. While this sounds tempting, it may be redundant for high-speed UFS 3.1/4.0 drives, and even slightly reduce memory life. Only enable this feature if you really feel a lack of RAM in multitasking.
Security, Backup and Services
The final stage of setting is data security. In addition to the unlock password, be sure to activate the Find Device function in your Mi Account. This will allow you to remotely lock your phone, erase data or play back sound if the gadget is lost. You can check the status in the Settings menu → Mi Account → Find the device.
Backup is a safety net against any failures. Set up automatic data storage in Google Drive or Xiaomi Cloud. Under Settings → About Phone → Backup and Restore, you can create a full copy of the system to an external media or computer, including Wi-Fi passwords and desktop icons.
To make payments and personal data more secure, use the Second Space, which is a function of creating an isolated environment inside your phone, as if you had two different smartphones, where you can take out work apps or hide personal photos with a separate password or fingerprint.
💡
Regular backups to external media are the only way to guarantee data retention in case of breakage or failures when updating the firmware.
Check your payment security settings. Make sure that the Security app has activated antivirus and anti-malware site protection. Periodically update the virus signature database by pressing the appropriate button in the antivirus interface.
