Battery sharing has become a more widely used feature for smartphone users (especially on Android) who want to use their phones to charge other mobile devices they use. While Apple was rumored to be considering reverse wireless charging for the iPhone 15 lineup, it never happened. Said another way – no iPhones support reverese wireless charging at this time. But there were some big updates with the iPhone 15 series when it comes to charging and in particular with iOS 17. Obviously the iPhone 15 brought a new charging port into the picture with the transition over to USB-C and iOS introduced new ways to manage and conserve battery life, not just within the device but across other Apple products as well.
While iPhone 15 doesn’t have any reverse wireless charging capabilities, you can still use it to charge other compatible devices through a wire connected to the USB-C port. Here are just a few examples:
- AirPods
- Other iPhones
- Small electronics that accept USB-C charging (Up to 4.5 watts)
- Some Audio Devices
These connections take advantage of the USB-C port’s ability to handle both data and power over the same connection, offering flexibility and utility for various purposes.
