Apple has already officially introduced the iPhone 15 last week, where in addition to coming with USB-C based charger support, it also offers the ability to charge other devices through the use of a cable.
By offering this feature, it simultaneously allows users to charge other devices – for example, wireless earphones using the battery power available on the iPhone.
According to documents published by Apple, the iPhone 15 offers this reverse charging at a rate of 4.5W. With this support, it simultaneously allows users to charge electronic devices or accessories easily when there is no battery outside the house, and share the iPhone's energy to charge it.
