Samsung wireless charging can but nfc can not use NFC function Nokia 920 wireless charging , it is recommended that you: verify whether the phone supports NFC function. Check whether the phone is using the original battery Nokia 920 wireless charge , because the NFC contact point of some models of mobile phones is connected to the phone battery Nokia 920 Wireless charging ; Individual models (such as Note2) NFC contacts on the shell Nokia 920 wireless charger , please confirm whether the phone is using the original back shell.
Confirm whether to use the original charger; 【 Tip 】 Include charger plug and data cable; Some mobile phones have accelerated charging switch: setting - battery - accelerated wired charging - sliding open; Check whether the system has a new version and upgrade the system. If no, back up important data (contacts, SMS messages, photos, etc.) and try to restore factory Settings.
The steps to use are as follows: Place the phone or device on the charger that supports NFC wireless charging, and ensure that there is enough contact area between the device and the charger. The charger sends an NFC signal to the device, and the device receives and recognizes the signal. The device sends a request to the charger to start charging. The charger will start sending a wireless charging signal to the device, which will receive it and start charging.
Not via NFC Wireless charging technology; Wireless charge technology is derived from radio energy transmission technology, which can be divided into two ways of low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
Wireless charging and NFC do not conflict, first to Nokia 920 wireless charging Your mobile phone supports wireless charging. NFC stands for Near Field Communication. It's by Fei LiPu Company initiated a wireless technology jointly promoted by Nokia, SONY and other famous manufacturers. Like RFID, NFC information is also transmitted through electromagnetic induction coupling in the wireless frequency part of the spectrum, but there are still big differences between the two.
Nokia 920 can be charged wirelessly Nokia 920 wireless charge , using Nokia920 Wireless charging is the QI wireless charging standard. Nokia Lumia 920 built-in wireless charging, just put the phone on the wireless charger tray, you can start charging the phone.
This wireless charging technology is based on the principle of electromagnetic induction, by embedding induction coils on the back of the phone, and a special wireless charging pad or wireless charging base for contact charging. When the Nokia 920 is placed on a wireless charging pad or charging dock, a magnetic field is generated between the induction coil and the charging device, and electrical energy is transmitted through changes in the magnetic field.
Nokia 920 Supported NoneLimited charge. Need to buy a wireless charging base, when you need to charge, put the phone back shell attached to the charging base to charge. During the wireless charging process, the phone will heat up, pay attention to safety.
If the Nokia 920 wants wireless charging, it needs to be placed on the corresponding wireless charging board, wireless charging headrest, and wireless charging speaker. Once moved away from a certain distance (more than 2cm in theory) can not charge Nokia 920 wireless charge , so in this case Nokia 920 wireless charge we still needThere is a loss of energy conversion and transmission during charging, so the charging speed may be slightly slower than that of wired charging. At the same time, in order to ensure the charging effect and safety, it is recommended to use regular brands and quality wireless charging equipment.
Nokia 920 can be charged wirelessly, using the QI wireless charging standard. Nokia Lumia 920 built-in wireless charging, just put the phone on the wireless charger tray, you can start charging the phone.
The Nokia 920 supports unlimited charging. Need to buy a wireless charging base, when you need to charge, put the back shell of the phone against the charging baseIt can be charged. During the wireless charging process, the phone will heat up, pay attention to safety.
If the Nokia 920 wants wireless charging, it needs to be placed on the corresponding wireless charging board, wireless charging headrest, and wireless charging speaker. Once moved away from a certain distance (more than 2cm in theory) can not be charged, so in this case we still need some wireless charging board and other devices, the distance is still very close.
1, represented by Nokia 920 Nokia 920 wireless charge The specific principle of electromagnetic induction wireless charging is that there is a coil at the transmitter and receiver. The coil at the transmitter is connected to a wired power supply to generate an electromagnetic signal Nokia 920 wireless charge , and the coil at the receiver senses the electromagnetic signal at the transmitter to generate a current to charge the battery. If the Nokia 920 wants wireless charging, it needs to be placed on the corresponding wireless charging board, wireless charging headrest, and wireless charging speaker.
2In short, the wireless charging technology of Nokia 920 provides users with a more convenient and flexible charging experience through wireless inductive charging. When using, it is necessary to pay attention to the special wireless charging equipment, and pay attention to the charging speed and safety.
3, Nokia 920 battery generally within 2 years will not appear too large durability decline, wireless charging has less impact on battery life, the better way to charge is to use the original charger, try not to let the battery completely exhausted and do not charge while using the phone. First of all, the Nokia 920 uses lithium-ion batteries, which are used in current smartphonesIn terms of lithium batteries, there will be no obvious insufficient power within 2 years of normal use.
Hi! The wireless charger needs to be connected to the power socket through the charging cable, and then the phone can be charged directly in the corresponding position of the charger. If it is a DC-50 portable wireless charging board (that is, a mobile power supply that supports wireless charging), openAfter starting, the phone can be directly placed in the corresponding position to charge.
There is a charging pad, one end of the socket, one end of the table. The charging of the phone is placed on the board, and it starts charging. I'll get you a map. It must be placed on the top, the advantage is that it can be put on at any time, such as the office, a lot of phones, 920 battery life is poor, so that you can finish the phone and put on the charge. It keeps the charge. Not much use. I don't have it.
It should be noted that the wireless charging function of the Nokia 920 needs to be used with a special wireless charging board or charging dock to achieve wireless chargingElectricity. In addition, due to the loss of energy conversion and transmission during wireless charging, the charging speed may be slightly slower than that of wired charging. At the same time, in order to ensure the charging effect and safety, it is recommended to use regular brands and quality wireless charging equipment.
