In 2020, Apple introduced MagSafe wireless charging support in the iPhone 12 series powered by magnetic charging coils at the back of the smartphones. Since then, it is claimed that Apple was working on iPhone reverse wireless charging tech based on patents, and FCC listing.
Although the tech didn’t debut in iPhone 12 series (2020), iPhone 13 series (2021), and iPhone 14 series (2022), the company is still working on the iPhone reverse wireless charging tech, reportedly.
Apple to release iPhone reverse charging feature via new wireless power-out the firmware
The alleged iPhone reverse charging tech would not only support MagSafe wireless charging but also power Qi-enabled accessories like AirPods by placing them on the back of the smartphone.
Now, 9to5Mac reports that the tech giant is developing a “unique” wireless power-out firmware for iPhone reverse wireless charging tech which is being tested internally. The main challenge in the development of the feature is to manage heat dissipation when reverse charging another device.
Internally, Apple is developing a unique “wireless power out” firmware as the basis for the feature. The work on this firmware is a major aspect of the ongoing testing and engineering of the reverse wireless charging hardware. One of the key aspects of bilateral charging is managing the charging speeds between the iPhone and the other device, including heat dissipation and charging efficiency.
The tech giant is also working on creating a new interface for the upcoming feature including animations, sound effects, and more.
Apple is also developing a special user interface for reverse wireless charging, similar to what is currently used for MagSafe chargers and accessories. This would include on-screen animations that help teach users how to use the feature, as well as a sound effect to indicate that bilateral wireless charging had been initiated.
Having said that, the publisher’s source cautioned that the feature might be delayed or shelved if the heat management issue is not resolved.
Apple was also allegedly building a wireless charging mat, AirPower which was eventually scrapped because the company could not resolve an overheating issue when charging Apple Watch on the wireless charging mat, along with AirPods and an iPhone.
