One of the latest rumors say that they will come to the next model of iPhone, which currently referred to as iPhone 8, 2017 iPhone or iPhone for the tenth anniversary, is that you can charge wirelessly, i.e., away from the surface or device that generates energy. Initially it was believed that Apple would use technology from Energous, but new information leads us to believe that it will not be so.
The CEO of Energous, Steve Rizzone takes time, ensuring that your company has reached an agreement with “one of the largest electronic companies in world consumption”, which, taking into account that Samsung uses its own technology, led many people to think that that company was which leads Tim Cook, in other words, Apple. But a note for investors of Copperfield Research explains why those of Cupertino will not use a wireless charging solution of Energous WattUp radio frequency.
New rumor says that the iPhone 8 will be charged by induction
Copperfield Research examined several Apple patents regarding the charging by induction that began to occur in 2013. Right now, the number of patents on this technology overcomes the dozen, it seems a symptom that Cupertino plan using its own system for induction for their future projects.
Patent does not make clear what plans to implement Apple, but in one of them we can see as Tim Cook and company say the technology is “very inefficient”, “not practical” and dangerous:
In any case, this type of transfer by radio is very inefficient because only a small part of the energy supplied or radiated, say, that portion in direction of, and overlapping with, the receiver is collected. The great most of the energy is radiates out in all them others addresses and lost freely in the space. So inefficient energy transfer could be acceptable for the transmission of data, but it is not practical to transfer useful amounts of electricity in order to perform the work, such as charge electric devices. […]
In addition, such schemes can pose dangers to objects or people crossing the beam when you are transmitting high or modest amounts of energy.
Moreover, Copperfield Research also says that Apple is associated with Lite-On Semiconductor for use rectifiers of bridge, what is used to convert current alternating (AC) in current continuous (DC), a component necessary for the load by induction and what not would be necessary if them of Cupertino decided based is in a module all in one as the of Energous.
One of them rumors on the iPhone 8 ensures that Apple will use a housing of glass for your next phone intelligent, what also us makes think that said terminal is charged by induction: the housing of glass not would be required for it load wireless, but itself for the load by induction.
Load wireless ≠ charging by induction
Many patents on the load induced by Apple talk about improvements that have been made in Cupertino in this area and give us clues about how would run a system developed largely by the company that Tim Cook directs. According to these patents, a same charger or surface of load could charge several devices, as a table with a coil of load integrated, a station of load of desktop or even a computer of desktop or laptop could be used to provide power to an iPhone or iPad. In addition, devices could share power between them, which would mean that an iPad could charge an iPhone or vice versa.
The problem with all of this and what insurance you are thinking many of you is that the charging by induction is not the same that the wireless load which had discussed several rumors. Charging by induction requires us to have a device stood on top of a surface, while the Wireless charging would allow us to charge a device while we have him a safe distance from the transmitter’s power. For this reason, I don’t want to believe me that what will launch Apple with iPhone 8 is a system of charging by induction 2.0. Already ago years that there are devices that use the load by induction and, to lack of see what would bring the system of them of Cupertino, the iPhone would come very afternoon to include this function. In any case, we are in January and the iPhone 8, iPhone of 2017 or iPhone of the tenth anniversary is present, if not there are surprises, in September.
