Rumor: "iPhone 8" would have charging by induction, but not completely without contact

It's been a long time since we started hearing rumors about the possibility of "IPhone 8" have some kind of wireless and contactless charging. This idea intensified even more after the company Energous, creator of WATT technology, entered into a partnership with one of the largest consumer electronics companies in the world.

However, going in the opposite direction, new research by Copperfield Research for investors suggests that the Apple considers this type of technology “inefficient, complicated and dangerous”. Thus, they analyzed and compiled possible reasons for Ma to discard wireless and contactless charging, preferring wireless charging by induction.

This type of radioactive transfer is very inefficient because only a small portion of the power supplied or irradiated, i.e., that portion that would be in the direction or superimposed on the receiver, is collected. The vast majority of the energy radiated away, in all other directions, and is lost in free space. Such inefficient energy transfer may be acceptable for data transmission, but it is not practical to transfer useful amounts of electrical energy for the purpose, for example, of charging electrical devices.

() In addition, such schemes can pose hazards to objects or people that cross or cross the beam when modest or high amounts of energy are being transmitted.

To give more weight to this argument, the research is still looking at a 2013 patent, which may have evolved considerably since then and may indicate that Apple would be opting for a domestic inductive charger instead of radio waves.

Another argument used was that Apple would be relying on the help of Lite-On Semiconductor to supply chips for the next iPhones, which would enable faster charging by induction.

And, contrary to what was suggested by analyst Ming-Chi Kuo (from KGI Securities), the supposed completely glass case of the “iPhone 8” would not be to facilitate wireless and contactless charging, but an evidence that Ma I would be planning to use wireless induction charging.

It is a big mistake by tech blogs and WATT investors that Apple's move to a glass housing in no way confirms the inclusion of WATT's charging technology. This is ridiculous. The efficiency of wireless RF charging (WATT technology) is not affected by aluminum or plastic housings.

Apple patents also show a charging concept with several objects that could provide power, such as a table top with a built-in charging coil, a desktop charging station or even a desktop or notebook computer; everyone could carry both iPhones and iPads. Even, as the image below illustrates, the devices could even share energy between them.

Despite the theories, Copperfield is not unaware that there may be a partnership between Ma and Energous, but with the aim of researching wireless charging by radio waves; even so, it hits the key that there is an “overwhelmingly conclusive” picture that the technology used in the “iPhone 8” will be that of domestic induction charging.

As we know, a company having a patent does not necessarily mean that we will see something like that in the near future. Especially if we are going to analyze that, if the technology works as we saw in the first image above, where would anyone rest their hands on the MacBook? Either way, the two options look better than thousands of strands scattered everywhere.
