Xiaomi Redmi Note 9 Pro is one of the most popular mid-range smartphones, equipped with a module NFC for contactless payments and data. However, not all users actively use this feature: some are afraid of accidental write-offs, others want to save battery power, and still others simply do not see the need for it. In this article, we will discuss all possible ways to disable NFC on your device, from standard settings to hidden chips MIUI.
It is important to understand that NFC deactivation does not affect the operation of other wireless modules (Wi-Fi, Bluetooth), but can limit the functionality of some applications, such as Google Pay, Mi Pay or contactless transport systems. If you use a smartphone for fare or purchases, it is better to leave NFC on, but configure it correctly.
We tested all methods on the Redmi Note 9 Pro with the latest MIUI 12/13/14 (including global and European firmware) and the instructions are valid for other Redmi Note 9 models, but may vary slightly depending on the software version.
1. Disable NFC through the phone's basic settings
The most obvious and safe way to do this is to use a standard settings menu, which is suitable for all versions of MIUI and does not require any additional knowledge.
- Open the Settings app (the gear icon on the home screen).
- Go to Connections and Sharing (or Network and Internet in some firmware).
- Slip on the NFC item β itβs usually located next to Bluetooth and Wi-Fi.
- Turn the slider to the off position (grey).
After that, the NFC module will be completely deactivated and the icon in the notification panel will disappear. If you use contactless payments, the system can request a confirmation of disconnection - that's fine.

β οΈ Attention: On some firmware MIUI post-off NFC The background process of com.android.nfc may remain active. It consumes a minimum amount of energy, but if you want absolute savings, use the methods in the following sections.
2. Quick shutdown via notification panel
If you need to temporarily deactivate NFC (For example, to avoid accidental payments in transport, the most convenient way to use the quick settings panel is to use it only if the icon is used. NFC already added to the curtain:
- Swipe your finger down to open the notification panel.
- Find the NFC icon (usually stylized as the letter "N" or the contactless card icon).
- Slap it once β the module will turn off, and the icon will turn grey.
If the NFC icon is not in the curtain, it can be added:
- Deploy the notification panel in its entirety (swipe twice from top to bottom).
- Click on the pencil icon (Edit).
- Find the NFC in the list of inactive icons and drag it to the top bar.
This method is convenient for those who periodically turn on/off NFC, for example, you can turn off the module at night or in places where contactless payments are not used.

3. Disconnect NFC through Power Saving Modes
The NFC module consumes power even in the background, so it is often turned off to save battery life. MIUI has two modes that automatically deactivate NFC:
- π Ultra mode β disables all background processes, including NFC, Wi-Fi and mobile data: Activated at critical charge level (typically below 5%).
- π Sleep mode β limits the operation of communication modules at night (from 23:00 to 7:00 by default). NFC shuts down with Bluetooth.
To adjust energy saving:
- Go to Settings β Battery and Performance.
- Select Power Saving Modes.
- Activate Ultra Mode or set up a schedule sleep mode.
β οΈ Attention: In the ultra-economic mode NFC It is forced to shut down and cannot be turned on until you exit this mode or connect the charger.
| Regime. | Shutting down NFC? | Impact on other functions |
|---|---|---|
| Ultra mode. | Yes. | Shuts down everything except calls and SMS. |
| Sleep regimen | Yes (night) | Limits background activity |
| Regular regime | No. | NFC is working by default |
4. Completely disable NFC through developer settings
For power users who want to block NFC from working at the system level, there is a way through the developer settings, which will come in handy if the standard shutdown does not help (for example, the module spontaneously activates).
First, you need to turn on the developer mode:
- Go to Settings. β The phone.
- Tap 7 times on the MIUI version (you will be notified "You became a developer!").
Now turn off NFC at the system level:
- Back to Settings β Additionally. β For developers.
- Find the Network section and select Disable NFC (or NFC-option).
- Check the checkbox. NFC-chip and confirm the action.
What to do if there is no "disconnect" item NFC-chip"?
This method is guaranteed to shut down NFC until the next reboot or manual activation, but beware: wrong actions in the developer settings can disrupt the phone.

If the module is activated after disabling NFC through the developer settings, check if it is enabled in the Second Space profile (to do this, go to Settings β Special Options β Second Space).
5 Problems After NFC Disconnection and Their Solutions
Sometimes users face unexpected consequences after deactivating NFC, and here are the most common problems and ways to fix them:
- π³ Contactless payments do not work: If you have disabled NFC, but Google Pay or Mi Pay still donβt work, check if the module is locked at the bank level (some apps require re-associating the card after rebooting).
- π± Phone does not read tags: Make sure NFC-The tag is compatible with the Redmi Note 9 Pro (some tags require special applications, such as the Redmi Note 9 Pro). NFC Tools).
- π NFC spontaneously switched on: This may be due to automatic rules in Settings β Check the Automation section for triggers for NFC.
If the phone starts to drain faster after the NFC shutdown, it may not be the module itself, but the background processes of the applications that try to activate it.
- Go to Settings β Applications β Application Management.
- Find apps like Google Pay, Mi Pay, SberPay.
- Limit their background activity or turn off autostart.
6.Alternatives to a complete NFC shutdown
If you donβt want to fully deactivate NFC but are worried about safety or battery consumption, consider these options:
- π Disable payments by default: In settings NFC (Settings β Connections β NFC) You can remove the tick from the default use of payment, so the module will work, but not activate when you accidentally bring it to the terminal.
- π΄ Use the blacklist: Some firmware MIUI This allows you to block specific NFC-Devices (e.g. terminals in transport) need applications like NFC ReTag.
- β‘ Limit background activity: C Settings β Battery β Using the battery find the process NFC Service and limit its work in the background.
Another useful lifehack: If youβre afraid of random payments, but want to leave NFC for other tasks (like reading tags), turn off Google Pay:
- Open the Settings β Applications.
- Find Google Pay and select Disable.
- For Mi Pay, do the same in the System Applications section.

Shutdown NFC It does not affect Bluetooth or Wi-Fi, but it may disrupt some smart devices (e.g., the device, NFC-Smart home key fobs or contactless car keys).
