After unpacking the new Xiaomi Redmi Note 9 Pro, users often encounter a rich MIUI shell that requires a competent initial configuration for comfortable operation. Modern smartphones offer hundreds of options, and getting started right avoids future autonomy and performance issues. We will take all the steps from on-set to fine calibration of the display.
This model is based on the powerful Snapdragon 720G processor, but without the right software optimization, its potential may not be fully realized. Many owners miss important steps in the developer menu or battery settings, which leads to unnecessary energy consumption. Our goal is to turn the device into a perfectly debugged tool.
In this guide, we're not just going to flip through the menu, but we're going to explain what each critical function is responsible for: you'll learn how to secure your data, speed up the interface, and set up your camera for better shots. Follow the steps carefully to get the most out of your gadget.
Initial activation and security of the account
The process starts with the device being turned on and the interface language selected, and at this point, the system will suggest connecting to the Wi-Fi network, which is a prerequisite for activating Mi Account. Without the account binding, many cloud services and device search features will not be available, so don't miss this step.
Pay special attention to the biometric protection setting. Redmi Note 9 Pro features a fingerprint scanner built into the power button, making unlocking instantaneous. Face unlock is also available, although it is less secure than a finger scan and only works in good lighting.
⚠️ Note: When creating a screen unlock password, do not use simple combinations like 1234 or 0000.
Once you have entered your password, the system will suggest you set up Google Pay and other ecosystem services, you should immediately add a payment card for quick payment in stores, and you should also activate Find the device, so that in case of loss you can remotely lock your phone or erase data.
The important thing is synchronizing contacts and photos, so if you're switching from another Android smartphone, use a built-in data migration tool that allows you to move apps, settings and media files over the cable or through the cloud, saving the folder structure.
Optimization of the display and the MIUI interface
The Redmi Note 9 Pro screen has excellent color reproduction, but factory settings often require adjustments to individual preferences. → You can select the color mode. For a realistic picture, choose Standard, and for more saturated colors, choose Saturated».
The screen refresh rate in this model is fixed at 60 Hz, but the system offers a function called Adaptive Brightness Adjustment, which must be activated to allow the light sensor to respond correctly to changing environmental conditions, which also helps to save battery power in the dark.
The MIUI shell provides a wide range of desktop customization options, you can change the application grid, add widgets, and use the theme. To access the advanced theme settings, go to the Themes app and select the Profile section where your downloads are stored.
💡
Enable In-pocket mode in the screen settings to avoid accidental taps when the phone is in your bag or pocket.
Don't forget to set up the navigation. Three virtual buttons may be active by default, but most users prefer gesture control. You can switch to Settings → Full Screen by selecting Full Screen Menu. This will free up useful screen space.
| Parameter | Recommended value | Impact |
|---|---|---|
| Color scheme | Standard/SRGB | Natural colors |
| Dark subject matter | Scheduled. | Reducing the burden on the eyes |
| font | Classic (Roboto) | Readability of text |
| Size of text | Medium. | Comfort of perception |
| Frequency of update | 60 Hz (fix) | Stability of work |
| Brightness | Automobile | Energy efficiency |
Energy and battery management
Autonomy is one of the key parameters of the Redmi Note 9 Pro due to the battery capacity of 5020 mAh. However, in order for the device to work for two days without recharging, you need to properly configure the energy saving system. → Battery.
The system offers several job profiles: Performance, Balanced, and Energy Saving. For everyday use, Balanced mode is optimal, which dynamically controls the CPU frequency. Performance mode should only be enabled in heavy games, as it significantly speeds up the discharge.
⚠️ Warning: Don’t use Super-Energy Saving mode all the time. It limits the background activity of all apps, which can cause you to miss important notifications from messengers.
Special attention should be paid to the management of application background activity. MIUI aggressively “kills” processes, which can interfere with the correct operation of social networks. Go to Settings → Apps → Permissions → Autorun and allow the launch only for necessary programs such as Telegram or WhatsApp.
☑️ Optimizing the battery
Also, disable unnecessary functions that consume energy in the background, including constantly searching for Bluetooth devices, NFC (if you are not using payment right now), and geolocation for system services.
Camera and photography settings
The 64MP main camera is capable of taking detailed pictures, but only when set up correctly. By default, the camera app can use pixel binning mode (combination 4 in 1), giving a photo of 16 MP. For maximum quality, switch to 64 MP mode in the camera settings menu.
An important parameter is to turn on the framing grid, which helps you build the composition according to the rule of thirds and align the horizon, and you can find this option in the settings menu of the camera application by activating the Grid switch. It is also recommended to turn on the display of the horizon level for architectural photography.
For low-light shooting, use night mode. In the Redmi Note 9 Pro, it activates automatically or manually through the mode menu. Processing algorithms take multiple images with different exposures and glue them together to remove digital noise.
Secrets of video shooting
And remember, macro photography, a separate camera module that allows you to focus 2-4 cm away from the subject, and it opens up the possibilities for textures, fine detail, and insects, and the quality of macro shots on this device is considered one of the best in its class.
System settings and hidden functions
For advanced users, there's a developer menu that hides important debugging and acceleration tools, and you have to click seven quick clicks on the build number in About Phone to activate it, and when you get an activation message, you'll see a new "Developers" item in the menu.
Inside this menu, find the Drawing section, where you can find the window animations, transition animations, and animation durations, and changing the value from 1x to 0.5x visually speeds up the interface, making the system's responses more sharp and responsive.
Another useful feature is "Don't interrupt work." By turning it on, you're preventing the system from unloading the application from RAM while it's open, which is critical for navigators or activity tracking applications that need to run continuously.
⚠️ Attention: The developer menu also has the option to "Remember actions." Do not turn it on unnecessarily, as this can lead to increased battery consumption and overflow of the system cache.
And you also have to look at the Second Space feature, which allows you to create an isolated environment in your phone, like you have two different devices, which is convenient for separating work and personal data, or for transferring your phone to children without accessing your files.
System update and maintenance
The first thing to do after setting up is to check for updates. Xiaomi regularly releases security and stability enhancements. Go to Settings → About Phone → MIUI version and click “Check Updates.” If a new version is available, download and install it.
Regular maintenance is also required. The Security app (standard for MIUI) has a Cleanup feature that deletes temporary files, cache and remnants of deleted applications, and it is recommended to run this procedure once a week to keep it running.
💡
Regular firmware updates close security vulnerabilities and often improve camera and communication modem performance.
Use the built-in Mi Cloud or Google Drive to back up your phone. Set up automatic contact sync, SMS and call logs. If your device is lost or broken, you can recover all the data on your new phone in minutes.
