Because of the technology and cost of wireless charging, generally low-end models do not support wireless charging, only those high-end flagships have wireless charging function. This means that only users who can afford high-end flagship have the opportunity to use wireless charging, the target group is limited, and it is still a relatively small part of the market, which cannot be popularized.
Disadvantage 2: Charging speed is not faster than line charging In charging speed, wireless charging compared to wired charging is still oneSet the gap. Experiments have shown that, taking the iPhone X as an example, in the same environment with the same power and current of the wireless charger to a full charge of only 1% of the battery is nearly half an hour slower than the wired charger. It greatly reduces the work efficiency.
There is also the function of wireless charging is not much high-tech. This idea is very good, but now the technology may not reach our expectations, that is, unlimited charging, the actual need for data cable, but not connected to the phone, but connected to the charger, in fact, still can not get rid of wired charging, so the phone's noThe limited charging function is now not supported by technology, and it will not feel good in actual use.
Some people say that mobile phone wireless charging is chicken ribs, the principle of wireless charging is to get rid of the trouble of cable. The principle of wireless charging is that the phone must be placed on a charging board when charging, and it can be charged as long as it is in the specified area. This is a kind of charging method with advantages and disadvantages, and some young people will choose to install such a charging seat at the bedside. If no one is home for a long time, there may also be some fire risk.Support wireless charging for the factory flagship machine, the price is too expensive, thisShould be an important factor. Looking at all the models that support wireless charging on the market at present, most of them belong to the flagship positioning and are expensive, such as Samsung Galaxy series, Apple iPhone X, iPhone8 series, the price of these products is often five or six thousand yuan, or even higher, which is destined to have a relatively small audience.
1, no good. The charging efficiency and charging distance of wireless charging are correspondingly limited, and wireless charging is not equipped with fast charging function.The charging speed is relatively slow, and the mobile phone can not be used when charging, and can only be placed on the charging station, so wireless charging is not good.
2, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
3, low charging efficiency, battery loss. Low charging efficiency: Wireless charging technology can reduce the use of data lines, and its charging efficiency is lower than that of wired charging. Battery loss: Heat generated during wireless charging can cause

Limited charging power Technology wireless fast charging , charging technology between different brands is not interworking now Technology Wireless Fast charge mobile phone power update quickly, a day to increase the power, from the original technology wireless fast charge 18W fast charge to Technology wireless fast charge now a variety of fast charge power, There are 30W, 45W, 65W, and now 120W super fast charging power, which also leads to a lot of wireless charging boards in the current world, and if you choose the wrong one, you can't experience the full charging power.
Due to the presence of electromagnetic conversion processHeating problems, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, wired fast charge has developed to 120W, and the fast charge carried by most mobile phones is more than 60W, which has surpassed the wireless fast charge, so wireless charging has gradually opened the gap with wired fast charge because of the technical requirements of the equipment.
In addition to the trouble of charging, wireless charging also has a serious defect, that is, the charging efficiency is too low (early products). There is also a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factorsThe merchant has to control the power.
Because of the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, in 2021, China's Ministry of Industry and Information Technology issued a technical requirement for wireless charging equipment, which has a clear provision: wireless charging rated power shall not exceed 50W. In order to comply with this regulation, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging.
