Xiaomi Redmi 9C: from unpacking to optimization

Xiaomi Redmi 9C is a popular budget model that requires a competent initial configuration for comfortable operation after unpacking. Many users face intrusive advertising in the system and a quick battery discharge if they ignore important steps of initial configuration. Proper preparation of the device for operation allows you to unlock its potential and avoid typical problems with the MIUI shell.

In this guide, we will discuss each step in detail: from activation to activation. SIM-You'll learn how to turn off the advertising services that are on by default in firmware, and how to adjust energy saving to extend battery life. Careful implementation of these steps will turn the standard device into a convenient tool for daily use.

Don’t rush to install heavy applications immediately after turning on, first make sure that the basic security and data synchronization settings are set up correctly, which ensures the safety of your personal information and the stability of the Android operating system in conjunction with the manufacturer’s proprietary shell.

Primary activation and basic parameters

Once the device is turned on, the system will suggest selecting an interface language and connecting to a Wi-Fi network. This step is critical, since without the Internet, you will not be able to log into a Google account and activate Mi Account. If you do not have a home network, you can distribute the Internet from another phone, but a stable connection is preferable for downloading updates.

Signing in to your Mi Account is required for Xiaomi cloud services, finding a lost device through Find a Device and synchronizing contacts, and it is not recommended to ignore creating or logging in to this profile, as it is key to the brand ecosystem.

  • 📱 Choose the right time zone to automatically adjust the time.
  • 🔒 Come up with a strong pattern lock or pin code to lock the screen.
  • 👤 Sign in to your main Google account to access the Play Market.
  • 📡 Allow contact synchronization so you don’t lose phone numbers.

⚠️ Warning: When setting up your screen lock, make sure to write or remember the pattern lock. Reset it without losing data on modern versions of Android is almost impossible.

In the initial setup process, the system may suggest installing additional applications or enabling cloud services, where it is important to be vigilant and uncheck unnecessary options to avoid clogging the device's memory with unnecessary software. The basic configuration ends with setting the date and time, which are usually automatically pulled up from the network.

Customization of the screen and interface MIUI

The Redmi 9C screen has a resolution of 720×1600 pixels, which is the standard for the budget segment. To improve text readability and usability, you should immediately adjust the font size and image scale. Go to Settings → Screen to adapt the picture to your vision.

MIUI offers flexible customization options, you can change the theme, you can set up live wallpapers or change the look of app icons, but it’s worth remembering that complex themes with live animations can be more battery-intensive, which is critical for devices with a MediaTek Helio G35 processor.

Pay special attention to the frequency of the touch screen survey. Although this model does not have high hertz, calibration of the sensor can improve responsiveness. If you think the phone responds to late touch, try turning off the option "Increase the touch" in special features, or, conversely, turn it on if you have a protective glass of high thickness.

To protect your eyes in the evening, be sure to activate the reading mode or "Vision Protection"; this blue light filter makes the screen colors warmer, reducing eye strain, and you can set the automatic activation of this mode on a schedule, for example, from 20:00 to 07:00.

Optimization of autonomy and battery

The 5000mAh battery is one of the main advantages of the Redmi 9C. However, in order for it to hold the charge for a really long time, you need to properly configure the energy saving system. By default, the system can aggressively unload background processes, which can cause notifications from messengers to arrive with a delay.

Go to Settings → Battery → Energy Saving. You can choose Balanced mode for everyday use. Economy mode limits background activity and brightness, which is useful when there is no charge at hand, but it is not suitable for constant operation.

It is important to configure specific applications, and if you use your navigator or messenger all the time, set background activity limits in No Limits mode, which will prevent the system from killing the process and ensure instant messaging.

💡

For maximum charge savings, turn off keyboard vibration and unnecessary system sounds in the Sounds and Vibrations section.

It's also worth checking battery usage statistics after a couple of days of use, and if you find an application that consumes energy disproportionately, try updating it or removing it. Often, poorly optimized applications from third-party sources are the culprits.

Security and Disabling Advertising

One of the most annoying features of the MIUI shell is the built-in advertising that can appear in standard applications like Explorer, Music, or when you unlock the screen. Fortunately, most ad modules can be manually disabled through system settings.

The first step is to turn off the msa service (MIUI System Ads). Find the settings for Passwords and Security → Access to Personal Data. In the list, find the msa service and turn off the switch. The system will ask multiple times and wait 10 seconds before turning off — that's okay, you just have to wait.

  • 🚫 Turn off “Receive recommendations” in the Security app settings».
  • 🚫 In the “Themes” application, remove the “Show Advertising” box in the profile settings.
  • 🚫 In Explorer, turn off "Receive Content" in the "About Application" section».
  • 🚫 In the Tools folder on your desktop, turn off "Get recommendations».

⚠️ Note: Complete removal of system applications through ADB It can disrupt the system and take away your warranty. Use built-in ad switches.

In addition to advertising, it is important to configure security. In the Security app, run the initial scan, it is also recommended to turn on fraud protection in call settings to block spam calls. Redmi 9C is relevant to install security updates that close the system vulnerabilities.

Memory and application management

The Redmi 9C model often comes with 32 or 64GB of internal memory, part of which is occupied by the system. To avoid problems with space shortages in the future, immediately set up the use of cloud storage and transfer media files. The built-in cleaner in the Security app will help remove temporary files.

It is recommended to immediately transfer the storage of photos and videos to the Google Photos or Mi Cloud cloud, enabling the “Free space” function. This will remove copies from the device that are already stored on the Internet.

☑️ Memory check

Done: 0 / 4

If you plan to use a microSD card, format it as a portable storage, not as part of internal memory, and this will ensure compatibility with other devices and reduce the risk of data loss when you reset your phone, and move music, videos and documents to the map.

Camera and multimedia setup

The camera in Redmi 9C is easy to control, but has hidden settings to improve quality. In Photo mode, turn on the framing grid to follow the rule of thirds when shooting. For portraits, use Portrait mode, which programmatically blurs the background.

In the camera settings, look at the save format. If the memory card allows, you can enable higher-resolution save, although there are enough standard settings for social networks. Also useful is the Face Improvement feature, but use it carefully to make the photos look natural.

For multimedia, you should set up an equalizer. Connect your headphones, go to the sound settings and select a profile that suits your music genre, or create your own. This will greatly improve the experience of listening to tracks through a standard 3.5 mm connector.

The secret of night photography
Use a tripod or wrap your phone around a stationary object, then turn on Night Mode and keep your phone still for 3-4 seconds, which dramatically improves detail.

Remember to wipe the camera lens before shooting, and the fatty finger marks create a soapy image and a glare from the light sources, which is especially noticeable on the budget matrixes installed in this model.
