The company did not manage to turn the concept into a working device.
A pad for wireless charging AirPower will not be released in the near future due to a number of problems in its operation. Apple can abandon the original idea and release a completely different product under the same name. This is reported in the blog Sonny Dickson, which is known for the publication of reliable leaks about Apple.
The site noted that there were three separate problems with AirPower. According to sources Sonny Dickson in Apple, first it turned out that the device overheats – rumors about this went for a long time. The high temperature of the mat during operation affected the charging speed of the devices on it, and also led to an overload of the internal chip that controlled the process.
In addition, the AirPower communication software was not working correctly – the mat did not transmit actual data on charging activation and device power levels. As noted in Sonny Dickson, a beautiful animation on the iPhone with the use of a rug was one of the main elements of its promotion, so for Apple this is a serious problem.
The third problem was the very idea of AirPower as a rug, on which you can charge three devices at once. As noted in Sonny Dickson, this is not offered by any other company, apparently, not just.
Apple decided to make it so that the devices could be placed on any part of the rug and they still charged. For this purpose, engineers used from 21 to 24 induction coils of different sizes, located close to each other in the entire area of the AirPower.
However, this solution gave rise to problems: due to the tight arrangement between the coils, interference appeared, and their efficiency decreased. The layout could also cause excess heat to be generated. According to Sonny Dickson, coil isolation is a particularly difficult task for engineers.
Sources of the site did not tell what will happen to the rug further. Journalist John Gruber said that Apple could either start work on it from scratch, or abandon the project. However, according to him, the company can use the name AirPower for some other device with wireless charging, but with a different concept. The journalist believes that to expect the appearance of AirPower in one form or another is not worth before the spring of 2019.
The AirPower rug was announced in September 2017 with the iPhone X and the Apple Watch Series 3. Apple promised that it will be available “in 2018”, but in June 2018, Bloomberg reported that the company faced difficulties and the project was moved to the fall.
During the September presentation about the rug never remembered from the scene, and from the site of Apple, his references were missing . Also, the company did not announce new AirPods, the case of which was supposed to be able to charge wirelessly.
