1, such a low charging power want to charge the mobile phone must be wait until the monkey year, BiHowever, NFC is not designed for charging, so this wireless charging solution is more for low-power IoT devices, such as smart watches, fitness trackers, wireless headphones, digital pens and other consumer devices. It doesn't make much sense for high-consumption electronic devices like phones or pads.
2, then, what is the significance of NFC wireless charging? NFC wireless charging can be used for wireless charging of small battery-powered devices (such as IoT devices, wireless headphones, smart watches, smart bracelets, etc.), and there is no need to redesign the charging unit separately.
3, I think that NFC support wireless fast charge on the mobile phone is more likely to affect the mobile phone integration NFC module, in the future, there are more supporting devices can achieve charging life through the mobile phone, greatly enrich the application scenario of the mobile phone.
1, we open the phone, click Settings. On the phone's Settings screen, we tap the battery. In the battery Settings screen, we tap Battery Health. In the battery health screen, we turn on the wireless charge switch. Just put your phone on thereIt's charging.
2, iPhone to turn on wireless charging method is as follows: Make sure your iPhone supports wireless charging function. Wireless charging has been built into the iPhone since the iPhone 8, and you only need to update the corresponding software version. Make sure your phone supports wireless charging by checking Apple's website or the phone's manual. Get a compatible wireless charging pad.
3. Open Settings to enter the phone Settings screen. On the battery Settings screen, tap Battery Health. On the Battery Health Settings screen, tap to enable wireless charging mode. Wireless charging technology introductionWireless charging technology, that is, the technology of transmitting electrical energy to the device by wireless means, is mainly divided into two ways of low-power wireless charging and high-power wireless charging.
4. First, make sure you have a compatible Apple device and a wireless charger. The Apple Wireless Charger is suitable for Apple devices that support wireless charging, such as iPhone 8 and newer versions, AirPods with charging cases, etc. At the same time, you need an Apple original wireless charger or a third-party wireless charger certified by Apple. The steps to prepare for use are fairly simple.
5, the use of Apple wireless chargingThe method is: first plug the Apple wireless charger into the power socket, then plug in the wireless charger will be powered on. Then you need to put the back of the phone on the wireless charger and the phone can start charging.
1, NFC is high frequency, used to transmit signals. Wireless charging has a low frequency and is used to transmit power. So there's no connection. NFC, the Chinese name is near Field communication. Is a short range high frequency radio technology made by non-contact radio frequencyIdentification RFID evolved from the joint development of Philips Semiconductor, Nokia and SONY, which is based on RFID and interconnect technology.
2, it does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large. Wireless charging and reverse wireless charging have become a common feature on high-end mobile phones, which use dedicated coils for radio energy transmission. Now the NFC Forum has announced the approval of a wireless charging specification that will allow users to wirelessly charge devices via NFC chips.
3, no, mobile phone wireless chargingHas nothing to do with NFC. The parts in the wireless charging of the mobile phone are called wireless collars, and only the mobile phone with the wireless collar can be charged wirelessly.
4, Conclusion: The magnet structure of the iPhone 12 magnetic wireless charger was exposed, showing its innovative design, taking into account the NFC function, wireless charging and NFC use do not affect each other. The following is a more detailed introduction: iPhone 12 back magnet layout iPhone 12 back uses 36 magnets, magnetic poles staggered, to provide a strong and accurate adsorption force for magnetic wireless charging.
5, NFC and wireless charging two powerIt seems that there is no relationship, in fact, there is not much difference in principle, in essence, they all use the principle of electromagnetic induction. For example, take the NFC access card for example, the mobile phone can sense the current and encrypted data in the card, the card does not need additional power, and the data exchange of this part of the communication is provided by the electromagnetic field established by the NFC component.
6, not through NFC, wireless charging technology from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi side of mobile phone chargingHow to recharge fc
Scan and recharge: Use a mobile phone or other NFC-supported device, open the corresponding payment application, scan the recharge QR code, enter the recharge amount as prompted to confirm the payment. NFC tag recharge: Place the NFC tag at the recharge point or designated place, use the mobile phone or device that supports the NFC function to sense the proximity, the system will automatically pop up the recharge page, enter the recharge amount according to the prompt to confirm the payment.
Open the phone, find a setting item on the desktop of the phone, and click to enter. After entering Settings, go down to the menu to find Wallet with Apple Pay column, click to enter. Once in your wallet and Apple Pay, tap Add a credit, debit or transit card. After entering the Add type, select Shanghai Transit Card or Beijing Card. After selecting the card type, select the recharge amount, and the NFC function can be used after successfully recharging.
Ensure that the NFC function of the mobile phone is enabled. Find and click "wechat". Click on "Me" - "Settings". Click and select "General". Click "Enable NFC Function". Attach your "bus pass" or "Metrocard" to the back of your phone. The wechat recharge page is displayed. Select the correct oneTo complete the "bus card" or "Metro card" recharge, click on the above denomination.
Users need to ensure that their mobile phones have NFC function, if there is no way to recharge the bus card. Open the NFC function of your mobile phone, and then open the Alipay of your mobile phone, there is a column of convenience life, and there is a "city card" option in convenience life, click directly to enter.
