Apple AirPower, the base wireless charging announced by Apple even in the distant 2017, to be then cancelled about a year ago, is recently back on track. The same source that had reported publicly, the youtuber Jon Prosser, is back on the topic with a series of new tweets and a video on his official channel.

Apple is trying to redesign the charging base in order to avoid the technical problems that led to the sinking of the first iteration – which, remember, had been presented as different from all other mats on the market: allows you to charge multiple devices simultaneously, without necessarily placing them in very specific areas. Apparently, The temperature problems were mainly caused by the Apple Watch, which uses a charging technology proprietary Apple requires more energy than traditional standard Qi. In most cases, the test of charging the interior of the smartwatch and ended up in the overheating of the entire block, often so intense as to generate a fire.

Using the A11, this new prototype has the ability to route power to specific coil regions and can dynamically wait for temperatures to drop before applying more power – preventing it from overheating.

The technology is kind of incredible.

The idea would be to use a smaller number of coils, but of much larger size. But not only that: a new prototype would be equipped with the same SoC of the iPhone X, Apple A11, which is able to dynamically manage the temperature and energy consumption. The chip can decide which coils to send energy, avoiding, for example, those that are too hot. Note that the AirPower original was an Apple A10.

While working from home, engineers on Apple’s ‘Sharing and Proximity’ team are receiving the prototype units of something called “C68“.

This prototype would have been sent to a small number of Apple employees, forced under the circumstances to work from home, additional tests and insights. The code name would be simply C68, and even if one does not speak expressly of AirPower is easy to perceive.

AirPower(2) update:

Apple believes is “necessary to push portless iPhone”

Codename “Callisto” (same as original)

Less but larger transmitter coils than V. 1 (trying to solve overheating w/less overlap)

Apple keeps a lot to AirPower because it believes it is an essential accessory for the advent of an iPhone without doors, the concept on which the company is thinking for a long time – and actually easy to guess as a “next step” for the sector in general, with obvious advantages of robustness, space-saving and water-resistance. For the moment it is not clear how much faster the charging, however, is expected to launch around the fourth quarter of 2020 or in the first of 2021. The price could be around 250 dollars.

Below the video, for those who are interested: the summary on the question of AirPower began around the fifth minute.
