#iPhone13 series wireless charging coil or will be larger

According to Max Weinbach, Apple plans to add a "larger" wireless charging coil to this year's iPhone 13 series, which will not only help to cool and boost power for wireless charging but may also pave the way for reverse wireless charging. Separately, Apple plans to offer reverse wireless charging for the next generation of iPad Pro by 2022.
Apple may find the feature more meaningful in the iPad Pro because the battery is larger.
