Unlock the phone Locate and open the Settings in the phone. 2, find the charging Settings open, and then find wireless charging in the charging Settings. Click on wireless charging, and change the wireless charging inside to wired charging.
Open Settings and click Battery.On the battery page, tap Wireless charging Settings. The function will always be on. Precautions for wireless charging: Choose the right charger to pay attention to the use of brand certified chargers, otherwise the device will be charged into the unstable, too high, too low current, resulting in damage to the device. At present, there are many different brands and quality wireless chargers on the market, and you should choose the right charger according to your needs.
Enter the phone Settings menu, select "Battery", and then click "More Settings", in this interface to enable the "wireless reverse charging" function. When this feature is turned on, your phone can provide up to 1 for other devices0W charging power to achieve emergency charging. Please note: - If you have not charged another device for a long time, this feature will automatically turn off. - This function cannot be enabled when the phone battery is less than 15%.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply equipmentThe transfer of energy to an electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
Wireless charging means providing electrical power to electronic devices wirelessly. Wireless charging is a modern technology that does not require a traditional physical cable connection to charge electronic devices. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to transfer power. There are many ways to implement the specific principles and technologies of wireless charging.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Wireless charging refers to the technology of providing electrical energy to electronic devices through wireless technology. Wireless charging mainly relies on wireless induction technology to achieve energy transmission. With the rapid development of electronic technology, the traditional wired charging method can not meet the needs of users gradually due to its problems such as inconvenient insertion and removal and limited equipment locationThe emergence of wireless charging technology has solved these problems.
Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
1, electric field coupled wireless charging, the principle is to transmit power by coupling two groups of asymmetric dipoles along the vertical direction of the induced electric field generated. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power.
2, wireless charging methods are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized lineWhen the coil (the charged coil on the phone) is close to the magnetic field, it generates an electric current, which charges the phone.
3, the first is electric field coupling charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
4, the principle of wireless charging is that through near-field induction, wireless charging equipment will conduct energy to the end of chargingThe terminal device converts the received energy into electrical energy, which is stored in the device's battery. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
5, wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signal, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to charge the battery, can be simply understood as a no magnetic core5W wireless charging power. iPhone 12, manufacturer number A2402, Qi certification ID 21491, supports 15W wireless charging power. iPhone 12 Pro, manufacturer number A2406, Qi certification ID 21492, support 15W wireless charging power.
