Your new iPhone 15 has a ton of cool features on board, including a way to charge other devices like the Apple Watch, a pair of AirPods, or even another iPhone.

The iPhone 15 series ditched Apple’s Lightning port with a new USB-C port. The change has been rumored for a long time for the 2023 iPhones and is one of the rumors that came true in September.

The switch to USB-C allows the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max to charge various other devices. This is useful if the battery life of your AirPods, Apple Watch, or other device is about to run out and you need a fast charge to extend the battery.

Fortunately, charging another device with an iPhone 15 is extremely easy with a USB-C connector or a USB-C to Lightning cable.

How To Charge Devices with iPhone 15

Apple says you can use your iPhone 15 to charge AirPods, Apple Watch, or other small devices that support USB power delivery up to 4.5 watts. It doesn’t mention that you can charge larger devices like another iPhone.

Now, keep in mind that charging is limited to 4.5W, which is enough for smaller devices like a watch or a pair of AirPods but only a little for larger devices like an iPhone. You can expect much slower upload speeds for large devices.

The iPhone 15 USB-C Port Can Charge Your AirPods Or Your Apple Watch

If, instead of a power source, you connect the charging box for your AirPods or the mini wireless charging pad for your Apple Watch to an iPhone, the iPhone’s battery will charge those devices. It’s the first time we’ve seen bi-directional charging on an iPhone. Of course, you will need a USB-C to USB-C cable or an Apple Watch charging pad with a USB-C at the other end, and you can choose when you bought the watch.

This is one of the new advantages of having a USB-C port on the iPhone, even if it is for 480 Mbit USB 2.0 data transfer only in the case of the iPhone 15 and 15 Plus, although it is 10 Gbit USB 3.0 in the case of the iPhone 15 Pro and 15 Pro Max, thanks to the A17 Pro’s USB 3.0 controller. 

All models will charge your AirPods or Apple Watch on the go, and we are sure that this will be a widely used functionality by millions worldwide because running out of charge on an Apple Watch is, unfortunately, very common.

iPhone 15 With Magsafe And Attached Wireless Charging Pad

Apple could have enabled the wireless charging receiver on the back of the iPhone to charge AirPods with a wireless charging case. Still, it has never released something like that, although there have been rumors of iPhone prototypes with this capability in the past.
