After unpacking the new smartphone Xiaomi Poco X3 NFC before the user opens up a huge potential that requires a competent initial configuration. Standard factory settings are often focused on conservative power consumption and demonstration of advertising content, which may not satisfy the experienced owner. Proper preparation of the device in the first minutes of operation can significantly extend the battery life and improve the overall responsiveness of the interface.
In this guide, we will go into detail about the activation process, the hidden capabilities of MIUI, and the critical steps to ensure data security. Ignoring some of the initial settings can lead to quick battery drain or inconvenience in everyday use. Let's turn a standard gadget into a powerful tool for work and entertainment.
Initial activation and setting up of Google account
The process of turning on the device triggers a sequence of system checks, followed by language selection and Wi-Fi connection. At this stage, the system will suggest updating, but for a clean installation it is better to skip the update right now and perform it later through the settings menu to avoid possible bugs of a fresh patch.
When you sign in to a Google account, the system will suggest you recover data from the cloud or other device. Choose carefully which apps and settings you want to move so that you don’t load your phone with unnecessary garbage. It’s often more useful to set up your smartphone as new by manually installing only the necessary software, which will ensure a cleaner and faster operating system.
⚠️ Note: When recovering from a backup, don’t agree to install all applications at once, which can cause the processor to overheat and put a heavy strain on the battery in the first hours of use.
An important point is to set up Google Pay (now Google Wallet).In order for contactless payment to work properly, you need to have an original certified security key installed in the system, and a reliable lock screen setting was set in the lock screen settings. PIN-Biometric data such as a fingerprint is added separately in the security section after the initial setup is completed.
☑️ Primary account setting
Screen optimization and refresh rate
One of the key features of the Poco X3 NFC is the high refresh rate display. By default, the system can use adaptive mode or standard 60 Hz to save energy, but to get a smooth picture, you need to manually activate the maximum frequency. To do this, go to Settings → Screen → Update frequency and select 120 Hz.
You also need to pay attention to the resolution of the screen. → Screen. → Screen resolution available in two modes: HD+ and FHD+. Use of the regime FHD+ (Full HD) It significantly improves the clarity of fonts and images, although it consumes battery power a little faster. For everyday use, the difference in autonomy is minimal, and visual comfort is significantly higher.
💡
Turn on the function "Increased contrast" in special features, if you often read text in bright sun - this will improve readability without increasing the brightness of the backlight.
Remember to calibrate color reproduction. In the color profile settings, you should choose Standard or Saturated mode depending on your personal preferences1, since the factory Auto mode can distort colors when viewing photos. Correct color balance adjustment reduces eye strain during long reading.
Managing Notifications and Disabling Advertising
MIUI, the system on which the Poco Launcher shell is based, is known for its aggressive marketing and built-in advertising. To get rid of intrusive recommendations in standard applications, you need to consistently disable the MSA service (MIUI System Ads). Go on the path of Settings → Passwords and security → Access to personal data, find in the msa list and turn off the slider, confirming the action for 10 seconds.
Next, you'll have to go through system applications like Explorer, Downloads, Music and Security, and find "Get Recommendations" or "Recommendations" in your settings and deactivate it, and this action will clear the interface of pop-ups and news feeds, turning your smartphone into a working tool.
- 📢 Turn off personalization of ads in your Mi Account through your browser by going to the privacy settings on the Xiaomi website.
- 🔒 In the Security app, turn off receiving updates and news to remove unnecessary tabs in the main window.
- 📵 Configure the notification filter by preventing the display of pop-ups for minor applications in the Notifications and Status bar section".
Once you do this, the interface will be much cleaner, and it's important to understand that some system updates can bring these settings back to their defaults, so it's not going to be superfluous to check these points periodically.
Setup of biometrics and security
The Poco X3 NFC fingerprint scanner is integrated into the on button, which ensures a high unlock speed. For the best result, when you first set up your biometrics, it is recommended to add the same finger twice as two different fingerprints, which will increase the likelihood of successful unlocking even if the finger is slightly wet or applied at a non-standard angle.
It also offers face unlock, which is not completely secure from a data protection perspective, as it uses a conventional front-facing camera with no infrared backlight. Face ID is recommended only for quick access to the desktop, but not for confirmation of payments or login to banking applications.
| Protection method | Speed of operation | Level of security | Working in the dark |
|---|---|---|---|
| Finger scanner | Tall. | High-pitched | Stable. |
| Face unlocking | Very high. | Low. | Requires lighting |
| pattern lock | Medium | Medium. | Stable. |
| PIN-code | Low. | High-pitched | Stable. |
To increase privacy, activate Hiding Notification Content on a locked screen, which will prevent message text and confirmation codes from being displayed before unlocking your device, and it’s also helpful to set up a second space or guest mode if you plan to transfer your phone to other people for calls or games.
What if the scanner stops recognizing the finger?
Battery Optimization and Application Management
The 5160mAh battery in the Poco X3 NFC offers excellent autonomy, but only with the right setup of background processes. MIUI has an aggressive power saving mechanism that can prematurely close the applications you need, such as messengers or navigators. To avoid this, you need to adjust the restrictions for each important application individually.
Go to Settings → Applications → All apps, select the desired application (such as Telegram or WhatsApp), go to Battery and select No Limits mode. This will allow the application to run in the background without interruptions, guaranteeing instant messaging. For games and heavy apps, you can enable acceleration via Game Turbo.
- 🔋 Turn on “Optimize Night Charging” to extend battery life when charging at night.
- ⚡ Use the original 33W charger to activate fast charging and avoid overheating.
- 📉 Turn off auto-run for apps you don’t use daily via the Permissions menu. → Auto-start".
Dark Mode not only reduces the strain on the eyes at night, but also saves the energy of the display, as black pixels on the screen are not only used. AMOLED-screens (although here) IPS, Savings are still due to the reduction of overall brightness and contrast, consume less resource. Set up automatic theme switching on schedule for maximum comfort.
💡
The correct setting of background constraints is a balance between autonomy and functionality: do not let the system “strangle” important messengers.
Additional features and hidden capabilities
In addition to basic settings, the Poco X3 NFC has a number of features that you should activate immediately, such as one-handed control, which is convenient for users with small palms, activates a swipe down the bottom bar of navigation, and the feature "Increased menu", which allows you to quickly switch the flashlight, screenshots and voice recorder without unlocking the screen.
Special attention should be paid to the vibration settings, you can choose from a variety of tactile response modes in the sound menu, or even create your own rhythm. The quality of the keyboard vibration response makes the printing much more pleasant and allows you to type faster, feeling the confirmation of each click.
Make sure the NFC settings are on, and Google Pay or MI Pay is the default payment app, and you can also set up an emulation of access cards in this section if your intercom or work pass supports standard frequencies, which will turn your smartphone into a universal key.
⚠️ Warning: Do not install applications for "acceleration" or "cooling" from unverified sources. They often contain viruses and, conversely, land the battery while running in the background.
The final touch is the gesture setting, and if you're used to button navigation, it allows you to keep the classic look. However, the switch to gesture control frees up the usable area of the screen and makes your smartphone experience more modern and smooth. Try both to choose the one that's most convenient for you.
