Charge and connect with the USB-C connector on your iPhone 15 - Apple Support

"You can use your iPhone to charge your AirPods, Apple Watch, or another small device that supports USB Power Delivery at up to 4.5 watts."

That is correct. Since a lightening iPhone does support USB Power Delivery it can be charged using a 15 series. I mentioned that I am currently charging a 13 with my 15 Pro Max

I’m literally charging my iPhone 12 with my iPhone 15 Pro so it it’s posible I charge from 10 percent to 32 my iPhone 15 was at 98 drop down too 89 so you do lose battery even if you don’t use the phone

Currently, only iPhone 15 models can charge other devices. It needs a USB-C to USB-C or USB-C to Lightning cable depending on the receiving phone. Just plug the cables into both phones and the receiving phone will start charging, though slower than a regular charger.
