How to use my IPhone to charge another phone

iPhone doesn't have the ability to charge another phone at this time. Whether Apple will offer reverse charging at some point in the future, no one here would know as this is a user to user only forum.

If you have an iPhone 15 series iPhone you can use it to charge an older lightening port iPhone (you would need an USB-C to Lightening cable. I think it can also charge another iPhone 15 series in certain situations. But if you don’t have a 15 series you can’t do this at all.

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."

You are indeed able to charge another iPhone with the 15 series. I know for sure you can charge a lightening port iPhone with the 15 Pro Max (charging an iPhone 13 Pro with my 15 Pro Max now). I think I read where you can charge another 15 series iPhone in some circumstances where the phones will detect which one has the lower battery and the other will then charge it but I’m not sure if the one charging needs to have a specific amount of battery charge before it can do it. Can’t test it right now because the other 15 Pro Max in the house is fully charged too.

I wasn't aware one could do this with an iPhone 15. And I own iPhone 15 Pro and 15 Pro Max. Learn something new everyday!

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 stumbled across the ability about a week after launch when my son forgot to fully charge his phone before we went to my other son’s football game. Out of curiosity I tried it and it worked. I then did a google search later that night and saw that others had figured it out. Technically the Apple article says it without actually saying it could charge other iPhones because it said it could charge another small device that supports USB Power Delivery. Just scanning through that article you would think it was saying only stuff that wasn’t another iPhone but when I thought about what it actually said it technically included at least the older iPhones.

It's good to know. Not something I'll likely ever have a need to use though. I have MagSafe at my desk at work and MagSafe at home. Pretty much everything I use, uses Qi charging and I'm really good at keeping everything charged up. But I'm glad to know this so I won't misguide anyone in the future.

Thanks

How to charge another iPhone with this phone

You need an iPhone 15, but if you do have an iPhone 15 model, see this --> Charge and connect with the USB-C connector on your iPhone 15 - Apple Support

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.
