Wireless charging once so cow, why manufacturers "abandoning treatment"? -Wireless charging-IT information

Wireless charging come out at the beginning, everyone is full of hope, to get rid of annoying cables and Chargers, after all, is a good thing. However, after the appearance of the final product to make people disappointed: complicated standard, the location of the phone demanding, slow charging, Wireless charging as a function of little value in the end. Of course, the new phones such as the Samsung S7 continues to support Wireless charging, but many vendors have "give up treatment." So, Wireless charging is there opportunity universality?

A tangle of wireless charging experience

This year, including LG, HTC's flagship phone, Wireless charging function is not supported. Even if Samsung S7 support many users without wireless charging as the absolute requirement of purchase. Although there are several mainstream standard, but Wireless charging basically for the Induction coil design, which will not only increase the thickness of the phone, but also need to phone back material not for metal, so more and more companies started charging for mobile phones equipped with wireless capabilities.

Fast charge is a better solution?

In the case of wireless charging has not yet been developed, Qualcomm presents a different way: quick charging, you can the phrase "charge for 10 minutes, calling the two-hour" are already familiar with. But it is clear that wireless and fast, in fact, are two different concepts, which pursues a more convenient and free of charge, and fast charge is not conflict. However, due to poor wireless experience, long time, so lets charge quickly became another selling point, but essentially, we still look forward to the real emergence and popularity of easy to use, efficient wireless power technology.

Is in the development of new technologies

Despite the negative development, but some companies are still working on wireless charging problems, we'll look at the promising ones.

First of all, is Qualcomm WiPower technique, it is compatible with standard Rezence, but the difference is not based on resonant coil induction technology, so you don't have to worry about insulating metal material interference in charging, charging position, also has better standard.

Another standard, it is multi-mode wireless charging. A4WP and PMA two wireless-charging standard after the merger, began to develop the technique, has been cooperating with NuCurren, Broadcom, developing multimode antenna. But instead of resonance, multimode just upgrade compatibility, still are dozens of coil technology, so it was more like a "band-aid".

Otherwise, Energous WattUp technology sounds interesting, it uses a new type of long-range RF technology, has now 4 metres can be achieved across the Wireless charging device does not need to be placed on the charging pad (cell phones need to be fitted with a mobile phone, of course). If Energous technology in the future supported by the mobile phone manufacturer, directly into the device, are very promising.

Summary

We are still unable to determine when wireless charging will be spread over a period of time, the underlying demand is still people buy smart phones is a beautiful, powerful, and easy to use. But what is certain is, Wireless charging is still in development, will one day meet consumer demand.

无线充电曾经那么牛，为何厂商纷纷“放弃治疗”？ - 无线充电 - IT资讯

无线充电问世之初，所有人都充满期待，毕竟能够摆脱各种烦人的线缆和充电器，是一件很棒的事情。然而，最终产品问世后则让人们无比失望：繁杂的标准、对手机放置位置的苛刻要求、缓慢的充电速度，最终让无线充电成为一种鸡肋功能。当然，如三星S7等新款手机依然支持无线充电，但很多厂商已经“放弃治疗”。那么，无线充电是否还有机会普及呢？

令人纠结的无线充电体验

今年，包括LG、HTC的旗舰手机，都不支持无线充电功能。即便三星S7支持，想必很多用户也没有将无线充电作为购机的绝对要求。虽然存在几种主流标准，但目前无线充电基本上均为感应线圈设计，这种形式不仅会增加手机厚度，同时也需要手机背部材质不能为金属，所以越来越多厂商开始不再为手机配备无线充电功能。

快速充电是更好的解决方案？

在无线充电一直未能发展起来的情况下，高通提出了一种不同的思路：快速充电，你可以对那句“充电10分钟、通话两小时”已经非常熟悉。但显然，无线和快速，其实完全是两个不同的概念，前者追求的是一种更方便、没有束缚的充电形式，与快速充电其实并不冲突。只是，由于无线充电体验差、时间长，所以让快速冲电成为了另一个卖点，但本质上，我们仍期待真正好用、高效的无线充电技术出现并普及。

正在发展中的新型技术

尽管发展不利，但一些企业仍在致力于解决无线充电的种种问题，我们来看看其中颇有前景的几种。

首先，是高通的WiPower技术，它兼容Rezence标准，但不同之处是基于共振而不是线圈感应技术，所以不必担心绝缘的金属材质干扰，另外在充电速度、充电位置等方面也有更好的标准。

另一种标准，则是多模无线充电。A4WP和PMA两大无线充电标准合并后，开始大力发展这种技术，目前已经与NuCurren、Broadcom合作，研发多模天线。不过，相比共振技术，多模仅仅是提升兼容性，几十方面依然是线圈技术，所以它更像是一个“创可贴”。

其他方面，Energous公司的WattUp技术听上去很有趣，它采用了新型的远距离射频信号技术，目前已经可以实现4米的隔空无线充电，设备不需要放置在充电板上（当然手机需要装上一个手机壳）。如果Energous的技术能够在未来获得手机厂商的支持，直接内置于设备中，无疑是极具前景的。

小结

我们仍无法确定无线充电究竟会在何时普及，在一段时间内，人们购买智能手机的根本需求依然是美观、强大、易用。但可以肯定的是，无线充电仍在不断发展中，会在某一天真正符合消费者的需求。
