Today to share with you why there is no universal knowledge of mobile phone wireless charging, which will also explain why mobile phone wireless charging is so slow, if you happen to solve the problem you are now facing, don't forget to pay attention to this site, start now!
< ul>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 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, is not acceptable, but also can not move, the position is off, the speed is lower.
The disadvantage of wireless charging is thatThe efficiency of most wireless charging is relatively low. Because relying on electromagnetic induction to charge, often the speed is relatively slow, and sometimes the phone needs to be quickly filled, then it is obvious that wireless charging is not as fast as directly using the phone to charge the data line.
Wireless charging support for the factory flagship machine, the price is too expensive, which should be a very 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, iPhonid=' Why has wireless charging been slow to spread? '> Why has wireless charging been slow to spread?
1, 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.
2, wireless charging application scenarios limited mobile phones want to wireless charging must use the charging baseIf you leave the base, the phone can not be charged, 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.
3, wireless charging from the once popular to the current depression, I think there are mainly the following reasons: First, the charging speed is slow compared with 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.

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 randomly equipped with wireless charging board, some third-party manufacturers also launched can be used for wireless charging accessories, although the form looks very high-end, but this kind of equipment need to install a special shell, the use is not very convenient.
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 cannot be charged on one sideWhile playing video games.
1. First, the charging speed is slower than that of 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. Wired charging can be simple to take a charger, or even notBring, borrow a colleague's or sweep a power bank to meet your needs.
2, most mobile phones do not support wireless charging mobile phone wireless charging concept basically everyone knows, but support wireless charging mobile phones are not many, most support wireless charger mobile phones are high-end flagship. According to the latest purchase report, most people now use mobile phones are about 2000 yuan, the cost of wireless charging is generally more expensive, and mobile phones in this price segment generally do not have wireless charging technology.
3, although wireless charging is the future research and development direction of mobile phone manufacturers, but the current developmentFrom the point of view, 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. 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.

But anyway, with the continuous change of technology, I believe that one day wireless charging can solve the problem of low conversion rate.
2, in addition to charging noConvenient, there is also a drawback that can not be ignored, that is, the charging efficiency is too slow! This is likely due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power.
3, charging power is limited, charging technology is not interoperable between different brands of the current mobile phone power update quickly, a day to increase a power, from the original 18W fast charge into a variety of fast charge power, 30W, 45W, 65W, and now there are 120W super fast charge power, This has also led to a lot of wireless charging boards in the worldMiscellaneous, if the wrong choice will not be able to experience the full charging power.
4, wireless charging from the once popular to today's depression, I think there are mainly the following reasons: First, the charging speed is relatively slow compared with 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.
1, wireless chargingThe reasons for the lack of widespread popularity of electrical technology are: the number of terminals is less two years ago, Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers followed up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
2, wireless charging board is not cheap mobile phone power has been rising, even the price of wired charger has increased a lot, the cost of wireless charging board is of course not cheap.
3, becauseThere is a heating problem in the electromagnetic conversion process, 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.
4, mobile phone wireless charging is not popular, mainly because the experience of wireless charging is very rubbish. Of course, the high price is also a very important factor. In terms of experience, wireless charging of mobile phones is shortBoard. 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.
