Will it have any effect if NFC is turned on all the time?

Always turning on NFC has an impact, mainly affecting battery life. Turning on the NFC function will increase the power consumption of the mobile phone. When NFC is always turned on on the phone, the NFC chip is in standby mode, which will increase the power consumption of the phone. However, the NFC function will be temporarily turned off after the phone is turned off. In addition to increasing power consumption, NFC has no other harm to mobile phones.

Many mid-to-high-end mobile phones support the NFC function. There are many introductions to NFC on the Internet. I believe everyone has a preliminary understanding. In daily life, NFC is mainly used to simulate transportation cards, access control cards, and bank cards. It can indeed provide convenience to life. But many netizens have doubts. NFC is bound to assets, such as simulating bank cards. Is it risky to leave NFC on all the time? Or, is always-on NFC also bad for phone performance?

First of all, leaving NFC on all the time does have an impact on the phone, mainly affecting battery life. When NFC is always turned on on the phone, the NFC chip is in standby mode, which will increase the power consumption of the phone, but the NFC function will be temporarily turned off after the phone is turned off. Aside from increased power consumption, NFC does no harm to mobile phones. Although the NFC function will increase power consumption, it consumes less power than components such as screens and external speakers.

Secondly, leaving NFC on has no risk to property. Can NFC be stolen? If it is a simulated bank card, then NFC is the function of a bank card, and you need to enter a password when swiping the card. Another issue that everyone is concerned about is the radiation issue. NFC is a high-frequency electromagnetic signal. There is definitely some radiation, but compared to WiFi and mobile phone signals, it is small and can be ignored.
