One of the more useful new features in the iPhone 15 is support for the new Qi2 wireless charging standard, which enables you to charge at up to 15W on compatible wireless chargers. But you don't need to buy a brand new iPhone to use it; all you need to do is wait a few days and you'll have the same feature on any iPhone 13 or iPhone 14 too.
The feature is coming in iOS 17.2, the next point release of Apple's iPhone operating system and which is currently in the beta stage known as Release Candidate, or RC for short. RC means that the software is pretty much finished and just needs a final kick of the tyres before it's made available to everyone.
