How to disable NFC on Xiaomi smartphones

Modern Xiaomi, Redmi and POCO smartphones have many wireless modules that run in the background. One of these features is NFC (Near Field Communication), which allows you to pay for purchases with a single touch, exchange data and use electronic passes. However, the constant active state of this module can consume little battery power, and also pose a potential risk of reading data in public places if the phone is unlocked.

Many users are wondering if you should keep this feature on permanently if you don't use contactless payment daily. You can turn off NFC on Xiaomi in several ways: through the Quick Access Panel or by delving into system settings. Turning off the module will not remove your cards from memory, but only temporarily stop them from working, which is convenient for saving energy.

In this article, we will take a closer look at all available deactivation methods, the nuances of the MIUI and HyperOS shells, and answer frequent questions about battery safety and impact.

Why to turn off NFC: pros and cons

The main reason users choose to turn off NFC on Xiaomi is to extend battery life. Although modern modules consume little power, in low signal conditions or with a constant search for readers, discharge can occur faster. In addition, disabling the feature increases the cybersecurity of the device, eliminating the possibility of unauthorized tag reading by attackers.

On the other hand, a complete shutdown will prevent you from instantly paying through Google Pay or Mi Pay. If you're used to paying with your phone, you'll have to turn on the module every time you buy. NFC-tags, such as switching sound profiles when bringing the phone to a specific point.

⚠️ Attention: Disconnection NFC It doesn't delete the associated bank cards from the apps, it stays in the phone's memory, but it stops sending the signal to the reader until the module is activated again.

The decision to disable the feature should be based on your use case. If you rarely use contactless payment, it makes sense to keep the module off by default.

Method 1: Quickly shut down through the notification curtain

The fastest and most convenient way to control wireless modules on Xiaomi smartphones is to use a control panel, often referred to as a “curtain,” which allows you to turn off NFC in a couple of seconds without having to go into deep settings menus.

To do this, swipe down from top to bottom across the screen. Depending on your MIUI or HyperOS settings, you'll see either a notification list or a switch bar immediately. If you see notifications, swipe again or click on the slider button to expand the full shortcut list.

Find an icon that says NFC. It usually looks like the letter "N" or the logo of the communication standard. If the icon is illuminated in blue or green, the function is active. Press it once to turn gray, which means that the module is deactivated.

☑️ Checking the shutdown NFC

Done: 0 / 4

If you don't find the right icon on the front pages of the panel, try scrolling through the list of switches left or right. Sometimes the shortcuts can be hidden in the second group of buttons. In some cases, the icon may be missing if it was removed by the user earlier from the button editor.

Method 2: Disconnection through system settings

If for some reason the icon in the curtain is missing or you need to access the advanced parameters of the module, you should use the classic path through the smartphone menu. This method is guaranteed to work on all versions of the firmware Redmi and POCO, regardless of the configuration of the quick access panel.

To get to the desired menu, follow the following steps:

  • 📱 Unlock the screen and find the Settings app (cog icon).
  • 🔗 In the list of main options, select Connection and Sharing (in older versions) MIUI It can be called "Additional Functions" or "More").
  • 📡 Find a line in the list that opens. NFC And press it.
  • ⭕ Turn the switch to the "off" position (gray).

In the same menu, you can adjust the behavior of the phone when tags are detected, for example, you can choose which application will run by default when scanning, or you can prevent automatic browser launch when reading advertising tags.

⚠️ Note: The path to settings may vary slightly depending on the version of the Android operating system and shell. If you do not find the "Connect and share" option, search by settings by entering the request "NFC".

Using Settings Search is the most reliable way to find the right option on any Xiaomi device. Simply type the word into the search bar at the top of the settings screen, and the system will redirect you to the desired section.

Configure Pay elements and payment security

Even if the NFC module is enabled, you can control which card will be used for payment by default, especially if you have multiple cards from different banks on your phone, and these settings are managed in the same menu where the module itself is enabled.

The NFC settings section often includes a Secure element or Security Item Location, where you select the encryption key store. Google Pay and its peers typically use HCE Wallet, and the wrong item can cause the phone to stop seeing payment terminals even if NFC is enabled.

What is HCE and why is it necessary?
HCE (Host Card Emulation) is a technology that allows you to emulate a smart card directly in the smartphone operating system, without using a physical Secure Element chip. It is thanks to HCE that modern payment systems on Android work, allowing you to store card data in the cloud and transfer them through NFC.> Also in this section, you can configure payment confirmation. It is recommended to set a mandatory screen unlock before a transaction. This will prevent random payment if the phone is just in your pocket next to the terminal, although modern Xiaomi smartphones have protection against such cases. For maximum security when visiting places with a large accumulation, you can also install a payment confirmation from the payment mode, you can use it in the nearest time. Impact NFC Battery consumption and performance: How much is the NFC It affects the autonomy of the smartphone, remains debatable. On the one hand, in standby mode, the module consumes minimal amount of energy while in passive scanning mode. On the other hand, with active use or a poor signal, consumption can increase. Comparison of energy consumption in different module use scenarios: Module state Battery impact recommendation Off Full deactivation No For maximum savings On (expectation) Background scanning Minimum (< 1% Daily use Active transmission Payment or data exchange Short-term spike Only when using Device search Constant active search Notable expense Avoid if not required As seen from the table, the main expense occurs only at the time of active search In standby mode, the impact on the autonomy of the Xiaomi smartphone is almost imperceptible against the background of the screen and mobile networks. 4G/5G. However, if your phone is running to its limits and you care about every percentage of charge, disable all unused modules, including the use of the device. NFC, Bluetooth and GPS, It's the right solution.

These are clears temporary system service caches. 📲 Check for system updates in the Settings menu → The phone. 🗑️ Clear the cache of the Google Play security app and system services. In rare cases, the problem may be hidden in the installed case. If the case is too thick or contains metal elements (for example, a magnetic fastener or a metal plate for attachment in the car), it can shield the signal or cause interference, which causes the module to work unstablely. ⚠️ Attention: If the icon NFC In settings, it is locked and not pressed, which may mean that the function is limited to regional settings or the device has superuser rights (Root) with modified system files. NFC You can use it when the air mode is turned on, in other configurations the system blocks all wireless interfaces simultaneously. 💡Stable work NFC Xiaomi is not only dependent on settings, but also on the physical absence of obstacles between the antenna (usually at the top of the case) and the reader.
