How to set up Xiaomi Redmi 9A: from unpacking to optimization

Xiaomi Redmi 9A has become one of the most popular budget devices on the market due to its excellent value for money. However, out of the box, the MIUI operating system installed on the device often contains many pre-installed software and advertising modules that can annoy the inexperienced user. Proper initial configuration allows you to turn this budget device into a convenient tool for everyday tasks, games and communication, significantly improving the speed of its work.

The configuration process begins immediately after the device is turned on and the interface language is selected. Many users miss important steps or, conversely, agree with all the system proposals, which subsequently leads to reduced autonomy and unnecessary visual noise. A competent approach to the initial setup will take no more than 15-20 minutes, but will save hours of nerves in the future, ensuring stable operation of the gadget.

In this guide, we will take a look at everything from connecting your account to fine-tuning your interface, how to turn off intrusive advertising, optimize battery consumption, and adjust security, and let you unlock the full potential of your Redmi 9A to make it as comfortable as possible.

Initial activation and configuration of accounts

Once you have chosen a language and Wi-Fi connection, the system will prompt you to log in to a Google account and create a Mi Account. Google profile is critical because it syncs your contacts, calendar and installed apps, and without this step, you will not be able to fully use the Google Play store and most of the company’s services.

As for Mi Account, it is not strictly mandatory for basic phone use, but it is highly recommended that you have this account, which allows you to use the Find Device function, cloud storage and the registration theme, be sure to include your real phone number and valid email address when registering, as they will be required to restore access in case of loss of password.

When activated, the system may suggest recovering data from the cloud or from another device. If you are switching from an old Android smartphone, it is a convenient way to quickly transfer all contacts and photos. However, if the device is new or you want a clean installation without unnecessary debris, you better choose the option of setting up as a new device.

Special attention should be paid to setting the time and date. Although they are usually pulled up automatically from the network, in some regions or when using specific carriers, manual adjustment may be required. Make sure that the Settings menu → Additional → Date and Time activates the "Use Network Time" switch to avoid the clocks being out of sync in applications.

Security and biometrics setting

Personal data security in a modern smartphone comes first. Xiaomi Redmi 9A features a fingerprint scanner located on the back, and also supports face unlock. Biometrics is set up via the Settings menu → Passwords and security. The fingerprint scanner works fast enough for the budget segment, but requires clear calibration when first used.

When you add a fingerprint, the system will ask you to put your finger on the scanner repeatedly, changing the angle of inclination. Don't ignore this step and try to touch the scanner with different parts of the finger pad. This will increase the accuracy of recognition in the future, especially if your hands are wet or dirty.

⚠️ Attention: Face unlock on Redmi 9A It's software-based through the front camera, not through the infrared sensor, which means that in total darkness, the function will not work, and there may be an error if you have a big change in appearance or use masks.

In addition to biometrics, you should also have a reliable PIN-This will be used as a backup login method and will be required to confirm payments to Google Pay or Mi Pay. Avoid simple combinations like “1234” or “0000” as they are easily picked up by attackers. SIM-cards when rebooting the device.

Optimizing the interface and removing advertising

One of the main features of the MIUI shell is that it has built-in ads that can be displayed in system applications. To get rid of them, you need to manually change several settings. The first thing you do is turn off the msa service (MIUI System Ads), which is responsible for displaying advertising materials. To do this, go to Settings → Passwords and Security → Access to data, find the msa application in the list and deny it access to the network.

Next, you should disable personalized recommendations in the applications themselves. In Music, Video, Explorer and Downloads, you need to find the settings (usually in the menu “three dots” or gear) and turn off the options “Receive recommendations” or “Show ads”, which will make working with system software much more enjoyable and cleaner.

You should also set up your desktop. Redmi 9A uses the Apple interface style by default, but the classic Android style (all the icons on the desktop) is more familiar to many. You can change this from Settings → Desktop. You can also remove unnecessary widgets and folders there, leaving only the necessary shortcuts.

Management of Notifications and System Applications

Chinese firmware versions and even global MIUI builds often have too many notifications from system applications. To keep your screen from burning up constantly because of weather news or app store promotions, you need to set up a notification center. Go to Settings → Notifications and Status bar → Application Notifications.

Here you'll see a complete list of all the installed programs. Go through the list and turn off notifications for apps that don't matter in real time. For example, the GetApps store or the system cleaner doesn't need to send push notifications about garbage every five minutes. Keep only messengers, emails and social networks active.

Special attention should be paid to the Tools folder where MIUI puts system utilities, many of which, such as the Scanner, Calculator or Dictophone, are useful, but their background activity may be limited. In the battery settings for each such application, you can choose the No Limits mode if you are critical to get data instantly, or the Battery Savings mode if the application is rarely used.

Battery setting and energy saving

The Redmi 9A features a 5,000mAh battery, which is a great indicator for a budget class. However, the processor and screen also consume energy, and the right setup will help extend battery life. The Settings → Battery menu has a "Battery Savings" mode that limits background activity and reduces processor performance.

For everyday use, a balanced mode is best. If you plan a long trip without charging, you can activate Ultra-Savings, but keep in mind that this mode will only work with calls, messages and basic functions. Also in this section, you can set a schedule for turning on and off power, which is useful for automatically restarting the device at night.

An important aspect is adjusting the brightness of the screen and timeout. Automatic brightness adjustment in the Redmi 9A works quite correctly, but sometimes can underestimate the values in the room. It is recommended to adjust the slider manually to your comfort and set the screen to auto-turn off for 30 to 60 seconds to save charge when the phone is idle.

💡

Use a dark theme of design. AMOLED-It saves energy on the screen, but even on the IPS-redmi matrix 9A It reduces the load on the eyes and visually hides the frame around the display, making the interface more pleasant.

Advanced system settings and performance

For those who want to make the most of Redmi 9A, there are hidden developer capabilities available. To activate this mode, you need to quickly click 7 times on the build number in the About Phone menu, and then the "For Developers" option will appear in the "Additional" section.

You can find animation speed settings here. Changing the scale of the window animation, transition and animation duration from 1x to 0.5x will visually speed up the interface. The phone will seem more responsive, although the physical power of the processor will not change. It is a simple and effective way to improve the perception of performance.

You can also limit the number of background processes in the developer menu. By default, the system manages the memory itself, but if you notice that applications are constantly being unloaded from memory (for example, music stops when the camera is opened), check the setting "Limit of background processes." For Redmi 9A with its RAM capacity, it is better to leave the value "Standard limit" or "No more than 4 processes".
