The Huawei Mate 20 Pro introduced reverse wireless charging in 2018. In 2019, Samsung added the function—called Power Share—to the Galaxy S10 series. The function transforms the back of your phone into a wireless charging pad that allows you to charge the phones of friends and family members. Additionally, you may utilise this function to charge a pair of true wireless stereo earphones while they are in a charging case.
Apple wanted to include reverse charging with the release of the iPhone 14, according to insiders familiar with the situation who spoke with 9To5Mac. The feature, according to the report, would have only been available on the iPhone 14 Pro, but the Apple's engineering problems caused it to miss the deadline for mass production.

According to rumours, Apple intended to use the function in 2019. This was found after the reverse charging function found inside the iPhone 11 Pro Max during a teardown. Even a Federal Communications Commission (FCC) filing made it clear the iPhone 12 featured wireless charging hardware but that reverse charging was inactive. However, It was also hinted at by the MagSafe Battery Pack for the iPhone 12. When the iPhone 12 was plugged in, the battery pack would have received power from the smartphone, according to 9To5Mac.
