Although charging speed is no longer the shortcoming of wireless charging, if wireless charging technology is to be popularized, wireless charging of mobile phones is far from enough. Wireless charging technology is no longer a new "black technology". Since the introduction of wireless charging into smartphones, the outside world has had a very divided attitude towards it. This is actually not difficult to understand, after all, getting rid of the shackles of wires and interfaces has long been the primary goal of many digital products. However, in the face of low charging efficiency, most people's attitude towards wireless charging is really "want to say that it is not easy to love you". Just a few days ago, Huawei released a number of models of the "Flagship of the Year" Mate20 series. Among these new models, the author found that Mate 20 Pro became the first wireless fast charging model with a power of up to 15W. It is reported that the wireless flash charging solution for Huawei Mate 20 Pro is provided by IDT. From the company’s official website, I found a 15W wireless charging receiver model P9221-R3 that supports two-way data communication. I believe this receiver is the core of Huawei Mate 20 Pro wireless fast charging + reverse wireless charging. From the introduction on the official website, you can learn that this receiver supports two-way communication, integrates a 32-bit ARM Cortex®-M0 processor, and has programmable output voltage, current limit, and foreign object detection settings. This receiver also has a patented overvoltage protection scheme to ensure charging safety during 15W fast charging. Before that, some netizens also revealed that OPPO is also testing 15W wireless fast charging technology. There are indications that 15W wireless fast charging technology may soon become the mainstream of wireless fast charging. The reason why the author has always emphasized that the wireless fast charging power reaches 15W is because this power has a "milestone" meaning. You should know that the current QC2.0 fast charge charging head power is mostly maintained at 14W~18W. If the wireless charging power can reach 15W, this means that the speed of wireless charging will catch up with ordinary wired charging or even fast charging. speed. Since 15W wireless fast charging solves the biggest weakness of wireless charging, which is slow, wireless charging, which has no obvious shortcomings, seems likely to usher in a popularization. But is the "spring" of wireless charging really coming? In this regard, the author is not particularly optimistic. While wireless charging improves power, wired fast charging is actually quietly improving. It is also the Huawei Mate 20 Pro. It has achieved 40W fast charging. Its fast charging specification is 10V 4A. The Honor Magic 2 that will be released at the end of the month is also rumored to be 40W fast charging, but the fast charging specification is 5V 8A. The charging speed has reached about half an hour to fully charge 70% of the power. In addition to the "lifetime rival" wired charging, the user experience may also be a major obstacle to the popularization of wireless charging. Although wireless charging can get rid of the shackles of the wire, the charging range can only be limited to the charging board. Although it is not a good habit to play with the phone while charging, in daily life, it is charged to talk about WeChat and swipe. Bo and the like are very common. In this habit, wireless charging requires that the mobile phone be placed on the wireless charging pad to charge when charging. In other words, every time the mobile phone is picked up, the mobile phone will be disconnected from the charging. The board can continue to charge. Compared with wired charging, there is only one line to "follow" itself, wireless charging seems to be more "bound" than wired charging. Although wireless fast charging technology is still difficult to replace wired charging for smart phones for a while, the prospect of the entire wireless fast charging is still very promising. In addition to the inseparable digital products of mobile phones, there are actually many digital products that are usually used to wait for it to be charged and are very suitable for wireless charging. For example, there are more and more fully wireless Bluetooth headsets. Most of these headsets are designed with headset + charging storage box. The storage box itself can be used as a headset to charge, and the storage box can also store a certain amount of power to facilitate users to increase battery life outside. For this reason, a wireless headset charging box that supports wireless charging is obviously very suitable for wireless charging. It has been rumored that Apple will update the charging box of AirPods. It is reported that the new charging box will support wireless charging. At the same time, Apple will also release a wireless charging pad called AirPower, allowing AirPods, Apple Watch, iPhone, etc. to have wireless charging Functional devices are charged at the same time. In the Mate 20 Pro, Huawei has also launched wireless reverse charging in addition to 15W wireless fast charging. Although combined with the previous news, it can be known that this reverse wireless charging may be designed for Huawei's new generation of all-wireless headset Freebuds 2 Pro, but the emergence of this feature has soon been jokingly described as "I want to buy a Mate 20 Pro for Charge your own iPhone". But it seems to be able to see from here that if reverse wireless charging is applied to laptops and other aspects, it is not without a market. In addition, some devices that are usually only used on the desktop are also quite suitable for wireless charging to a certain extent. Just last year, Logitech launched the wireless gaming mouse G703 and G903 that support wireless charging. Along with these two mice, there is also a mouse pad POWERPLAY that supports wireless charging. The combination of the two can basically achieve the effect of making the wireless mouse uninterrupted forever. In general, the author believes that the advent of 15W wireless flash charging will still promote the popularization of wireless charging in the smartphone market to a certain extent. However, if you want to "sit on an equal footing" with wired charging or even "completely replace", not to mention the future development of technology, it seems that it is impossible to do it in terms of user experience alone. Therefore, in my opinion, wireless charging should be used as an auxiliary charging method for smart phones, and then it is the best way to penetrate into more digital products.
