1, if the iPhone wireless charging suddenly does not charge, it may be because sometimes unpredictable errors occur in the update of the iOS system, which will cause problems with the wireless charging function, usually as long as the restart can be solved. Remove the iPhone case Sometimes the iPhone case is too thick will also cause wirelessAt this time, you can try to remove the iPhone protective case and then put it back on the wireless charging board to charge.
2, the iphone13 wireless charging flash may be the charging interface at the bottom of the phone into the gray, which causes poor contact between the interface and the power cord plug. So check the port at the bottom of the phone first to see if there are foreign objects blocked. Try to turn off and then turn on, it may be the reason of the system, resulting in the phone can not charge. There is also the problem of temperature, so that the phone is at a normal temperature.
3, hello, if you use a wireless charger, there is always an intermittent charging prompt tone,It should be that the back of your phone is not accurately placed on the wireless charging contact surface, and it may be that your phone case affects wireless charging, you can remove the phone case and try again.
4, if the iPhone vibrates when receiving a message, the iPhone may shift, which may also cause the charging station to stop charging. In order to extend battery life, if the battery overheats, the system may limit charging when the charge reaches 80%. When the temperature drops, the iPhone charges again. If your iPhone is hot, try charging itTerminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. 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 the connection of the charging base station and equipmentThe bridge.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
The way of wireless charging has electromagnetic inductionType, 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 coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Energy is transmitted by the power supply device (charger) to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation. Because the energy is transmitted between the charger and the electrical device in an inductive coupling, between the twoNo wire connection, so the charger and the electrical device can be no conductive contact exposed. Wireless charging mainly uses the principle of electromagnetic induction, magnetic resonance and radio wave technology.
1, the charging speed is slightly slower: compared with the wired charging bank, even if it has a fast charge, the charging speed of the wireless charging bank will be slightly slower, especially for devices with large capacity batteries, and the charging time is longer. compatibilityLimitations: Wireless charging banks require devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
2, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
3, the second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge on the go, compared to wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe,Faster, the disadvantage is that the charge is relatively slow.
4, wireless charging and wired charging bank compared to what is the difference? Although both are used to charge devices such as smartphones, there are some differences. Simply put, wireless charging is more convenient, does not require wire entanglement, can remove the trouble of wire; The wired charging treasure is faster in charging speed, such as the Secretary-General is a wired charging treasure, which supports PD two-way fast charging, and the charging speed is faster than the general product.
1Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

Wireless charging is fast charge or slow charge depends on the phone charger, if the charger is high voltage fast charge, wireless charging is wireless fast charge; If it is an ordinary charger, wireless charging is wireless slowCharge. The correct way to use a wireless charger: Connect the charger to a power source. Please use the charging head, charging cable and wireless charging base purchased by yourself. Place the charger on a horizontal surface or other location suggested by the manufacturer.
The second is magnetic resonance, which is also combined by a transmitting device and a receiving device. A frequency between the two devices needs to be tuned to the same stage, because only then can they resonate. But there is no way to commercialize this technology.
Wireless charging means that it is not connected to the end that needs to be charged without the traditional charging power cordThe charger on the end device adopts the latest wireless charging technology, and transmits electric energy magically by using the magnetic field generated between the coils.
