1， The basic principle of wireless charging
The basic principle of wireless charging is based on the conversion of the current into a magnetic field; this one is transmitted through the air and then converted into the current to the intelligent terminal.
The generation of a magnetic field occurs when an electric current is passed through a coil. There’s a change in the closed circuit magnetic flux and the generation of an Induced electromotive force.
The charging base is responsible for turning the current into a magnetic field, which is constantly changing.
A generation of the induced electromotive force for charging happens because of the constant change of the magnetic field and so of the magnetic flux in the coils.
There will be electrical coils behind the phone.
In addition, because metal has an electromagnetic shielding effect, this material is not usable for wireless charging to take place. Wireless charging will not work also if there are metal phone cases, or when there is metal in the transmitting coil (charging base) and receiving coil (usually the center of the back of the phone).
2， Wireless Charging Notes
Wireless charging has lower power, slower charging, and lower battery requirements than wired ones.
In addition, it isn’t handy as the classic charging method. There are some requirements to use wireless charging, for example, the distance and the accurate and fixed position of the phone. In this way, the user cannot be able to use his device while charging.
3， Advantages of Feiyu company Wireless Charging.
Feiyu company has many positive notes that will make users’ experience with wireless charging more comfortable and enjoyable.
- Innovative design between charger and phone to avoid the problem of misalignment of position using a magnetic connection.
- New closed magnetic field protection function to manage electromagnetic wave diffusion outside the coil. New charging method that allows the user to have not only horizontal charging but also every other position to use the phone. In addition, users can adjust the charging angle in different ways.
4， The impact of wireless charging on batteries.
Many people think that this way of charging phones could affect negatively their phone’s battery. Our wireless charging can make these people change completely their minds.
- Wireless charging does not harm the phone battery.
- Wireless charging reduces the use of data cables, making the charging method safer and freer.
- In exchange for slower charging than the data cable, it offers a higher power conversion rate that saves energy.
5， Does wireless charging hurt your phone?
The same issue of the battery is presented for the phone, but even in this case, our technicians will answer your doubts.
- Wireless charging will not harm the phone.
- Wireless charging operates at a frequency lower than 1M, so it will not affect the cell phone signal.
- To make sure it will not affect the phone, QI standard wireless charging, built-in wireless receiver, will have the rated voltage and current.
6， The wrong way to charge your phone.
In addition, there is some advice that our company wants to give to the user in order to list the wrong way to charge the phone.
- Do not start charging the phone until it is below 20%. An excessive discharge will seriously affect the life of the battery.
- It is dangerous to use the phone while charging. When it is being used, not only the charging speed will slow down but also the temperature of the phone will keep rising.
- Trying to avoid playing large games, watching Tiktok and making phone calls is a good way to not stress the battery because these activities increase the temperature when the phone is charging.
7， Damage of non-conforming products.
Using non-conforming products which are without overvoltage and overcurrent protection may cause unstable charging power and damage to the battery. In addition, the normal working temperature of cell phones is from 0°C to 40°C. Devices that reach a too-low or too-high temperature, beyond that range, will receive some damage to the battery. Wireless charging will produce heat loss. So it’s important to have an excellent quality product. In this way, it’s possible to have not only a high power conversion rate but also the ability to control temperature and heat dissipation. Consequently, the temperature will not be too high for the device’s standards.
8， Overuse of cell phones.
Normally cell phones should be charged once a day. If the device is charged 2/3 times a day, progressing with those who are charging cycles, the life of the battery will degrade faster. So it’s important to not overuse cell phones for the benefit of the battery.
