Apple iPhone 12 has 'secret' reverse wireless charging

Citing a series of US Federal Communications Commission (FCC) filings first spotted by VentureBeat, the report said that the iPhone 12 "supports a built-in inductive charging transmitter and receiver."

Apple has not officially announced any such functionality yet.

"In addition to being able to be charged by a desktop WPT [wireless power transfer] charger (puck), 2020 iPhone models … also support WPT charging function at 360 kHz to charge accessories," one of the documents read.

The list includes iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max.

The FCC documents said that "currently the only accessory that can be charged by iPhones is an external potential apple accessory in future" and that reverse charging currently "only occurs when the phone is connected to an AC power outlet."

Apple has officially introduced MagSafe in iPhone 12 series phones, offering high-powered wireless charging and an all-new ecosystem of accessories that easily attach to iPhone.

The MagSafe Charger makes wireless charging a cinch. The perfectly aligned magnets attach to your iPhone 12 or iPhone 12 Pro and provide faster wireless charging up to 15W.

The MagSafe Charger maintains compatibility with Qi charging, so it can be used to wirelessly charge your iPhone 8 or later, as well as AirPods models with a wireless charging case, as you would with any Qi-certified charger.

The magnetic alignment experience only applies to iPhone 12 and iPhone 12 Pro models, according to Apple.
