More hints — On Twitter, @EverythingApplePro also tweeted this photo and noted, "Yup. Official iPhone 12 cases will also have this magnet system built in. Likely for perfect alignment with Apple's wireless chargers."
What does this all mean? — So far, there is no official news of Apple reintroducing AirPower. In the past, issues around quality concerns seemingly stopped it in its tracks, but it didn't stop people from sharing fake photos just to quench their wireless charging thirst.
EverythingApplePro's info sounds very similar to what analyst Ming-Chi Kuo hinted at in January. At that time, he said that the company might release a small-sized wireless charging pad in the early half of 2020. With magnets, Apple may have solved the AirPower's overheating issues that led to its embarrassing cancellation. Instead of using as many as 24 overlapping coils, Apple could (in theory) use the magnets embedded in the iPhone 12 to align perfectly with the charging coil in its wireless charging pad. Mis-aligned charging solved!
Tame your hopes — Ming-Chi Kuo has a great track record and he's rarely wrong so we wouldn't put AirPower returning in smaller form past him. But also: Apple's prototyping team is constantly experimenting with concepts, designs, and devices. In 2019, a patent filing showed charging coils on a mat, indicating that Apple was playing around with the idea of a wireless pad that could charge without heating up. But it never materialized. For now, take the news with a pinch of salt. EverythingApplePro's photos are just speculation. We're going to have to go back to our charging cables or third-party wireless chargers for now.
