Speculation is mounting that Apple’s wireless charger AirPower is in a lot of trouble: not only was the charging pad completely absent during Wednesday’s iPhone event, Apple has also declined to discuss the product and scrubbed most, if not all, references to it on their official website. Some say it could have been scrapped entirely. I wrote about AirPower’s absence earlier this week. What I’ve heard, third-hand but from multiple little birdies, is that AirPower really is well and truly f*cked. Something about the multi-coil design getting too hot — way too hot. There are engineers who looked at AirPower’s design and said it could never work, thermally, and now those same engineers have that “told you so” smug look on their faces.
