1, wireless charging mobile phoneWhy are wireless charging phones rare? On the one hand, the inconvenience of its use form is an important factor. Although the early Nokia Lumia 920 has built-in Qi wireless charging technology, it requires a special case and base, which is not convenient to use. The base's size and charging distance limits also limit the user experience. 2, wireless charging mobile phone is not popular there are many reasons, the use of inconvenient form is the first reason, as early as three years ago, Nokia launched Lumia 920 built-in Qi wireless charging technology, and random equipped with wireless charging board, some third partiesManufacturers have also launched accessories that can be used for wireless charging, although it looks very high-end in form, but this type of equipment needs to install a special shell, and it is not very convenient to use.
3, wireless charging application scenarios limited mobile phones want to wireless charging must use the charging base, if off the base, the mobile phone can not charge, which is the same as the wired fast charge to rely on the charging line and charging head. The phone must be static, and it is impossible to play a game while charging.
4, wireless charging from the once popular to today's depression, I think there are mainly the following reasons: First, charging speedDegree is slower than wired charging. Now mobile phones are popular fast charging, 40 or 50 watts, 50 or 60 watts of output power, basically more than half an hour can be charged to more than 80%, which is wireless charging can not be compared. Second, portability and versatility are worse than wired charging.
5, the author thinks that there are several important reasons why wireless charging is difficult to popularize. First of all, practical considerations, although any mobile phone design, configuration technology are not the same, but basically the mainstream functions of everyone has, especially the user's favorite is not left behind, so the functions of smart phones are basically the same.What is different is the comfort of the experience and the micro-innovation.
6, for most ordinary mobile phones, the speed of wireless charging is still tolerable, after all, there is no data line directly inserted into the phone, and the speed can not be expected to be like the data line fast charging. But even in this way, the loss of the battery can not be ignored. It is important to know that wireless charging does not match or not match, and any mobile phone treatment is the same. The size of the current will directly affect the service life of the battery, so it needs to be improved.
Wireless charging mobile phone popularity limited factors Wireless charging mobile phone Why rare? On the one hand, the inconvenience of its use form is an important factor. Although the early Nokia Lumia 920 has built-in Qi wireless charging technology, it requires a special case and base, which is not convenient to use. The base's size and charging distance limits also limit the user experience.
Wireless charging mobile phone is not popular there are many reasons, the use of inconvenient form is the first reason, as early as three years ago, Nokia launched Lumia 920 built-in Qi wireless charging technology, and withThe machine is equipped with a wireless charging board, some third-party manufacturers have also launched accessories that can be used for wireless charging, although it looks very high-end in form, but this type of equipment needs to install a special shell, and it is not very convenient to use.
The main reason is that the wireless charging current is too small. Wireless charging is limited to material problems and technical problems resulting in low efficiency. Wireless charging is only suitable for use when sleeping, while watching and charging can not keep up. In addition, the wireless charger charger is too large, it is better to plug in the charger directly. The last one is that modern fast charging technology is unmatched by wireless charging.
Mainly because the wireless charging current is too small. Wireless charging is limited to material problems and technical problems resulting in low efficiency. Wireless charging is only suitable for use when sleeping, while watching and charging can not keep up. In addition, the wireless charger charger is too large, it is better to plug in the charger directly. The last one is that modern fast charging technology is unmatched by wireless charging.
In addition to inconvenient charging, there is also a drawback that can not be ignored, that is, the charging efficiency is too slow! This is most likely due to the presence of heat in the electromagnetic conversion processTaking into account the safety of electricity and other factors, manufacturers have to control the power.
Although wireless charging is the research and development direction of mobile phone manufacturers in the future, the charging efficiency of wireless charging is still less than that of wired charging. Coupled with the charging trouble, the cost is too high, so that this once popular charging method has become less popular. But anyway, with the continuous change of technology, I believe that one day wireless charging can solve the problem of low conversion rate. And now most of the mobile phones on the market are metal back cover, wireless charging needs glass or potterySuch a porcelain back cover cannot meet the needs of most people in a large range.
Wireless charging Charging speed is extremely slow, which is hard. Now is the world of high-power fast charging, although each fast charging solution is not the same, but the power is basically maintained at about 18w, high and even to 24w, accustomed to an hour and a half full, but now to return to the past, 5w 8w maximum 10w charging speed, really can not letPeople accept, and can't move, the position is sideways, the speed is lower. Second, the speed of wireless charging is really very slow, extremely low efficiency, its power is mostly within ten watts, and our mobile phone now wired charging power is generally more than 18 watts.
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 controlControl power. This is also a reason for the gradual disappearance of wireless charging.
Mobile phone wireless charging is not popular, mainly because the wireless charging experience is very rubbish. Of course, the high price is also a very important factor. In terms of experience, mobile phone wireless charging has shortcomings. Compared with wired charging, wireless charging of mobile phones is not only slow, but also very inconvenient to use wireless charging. Slow charging speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturers.
The main reason is that the wireless charging current is too small. Wireless charging is limited to material questions and technical questionsThe problem leads to low efficiency. Wireless charging is only suitable for use when sleeping, while watching and charging can not keep up. In addition, the wireless charger charger is too large, it is better to plug in the charger directly. The last one is that modern fast charging technology is unmatched by wireless charging.
1, first of all, the wireless charging efficiency is slightly low, the early equipment heating problem is serious, resulting in the back of the mobile phone hot, manufacturers have to make power controlCompromise. (Balancing safety and efficiency was a challenge in the early days of wireless charging.) Second, wireless charging bases often require additional purchases and are expensive, sacrificing portability. (The trade-off between extra cost and convenience is a big consideration for users.
2, the shortcomings of mobile phone wireless charging although the technical content of the equipment is high, the economic cost of the equipment is high, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
3, convenience: mobile phoneWireless charging eliminates the need for a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
