Apple’s iPhone 15 lineup has transformed the third-party accessory landscape, offering unprecedented flexibility with its shift from the Lightning port to USB-C.
This change has unlocked a host of new possibilities for Apple users, from gaming controllers to professional microphones, making the iPhone more versatile than ever.
One of the iPhone 15 series’ standout features is its ability to charge other Apple devices, including the Apple Watch and AirPods.
This seamless inter-device charging capability is a game-changer for Apple enthusiasts who are always on the go. Here’s a closer look at how this works and what you need to take advantage of this feature.
Charging Your Apple Watch with an iPhone
To take advantage of this feature, you’ll need an iPhone 15, iPhone 15 Plus, iPhone 15 Pro, or iPhone 15 Pro Max.

These models are currently the only ones capable of charging an Apple Watch, but we expect the upcoming iPhone 16 series will continue this trend.
Here is how to charge your Apple Watch using your iPhone:
- Ensure your iPhone 15 has enough charge, as it prioritizes its own battery life.
- Use a USB-C to Apple Watch MagSafe cable. Plug the USB-C end into your iPhone’s port.
- Attach your Apple Watch to the MagSafe connector, and watch as it starts charging.
The new iPhones can charge your Apple Watch really well, no matter which model you have.
They can also charge other small gadgets, like older iPhones, but not as quickly as some other devices.
So, while it’s great for charging your watch and other stuff, don’t expect lightning-fast charging for your phone.
Wrap Up
The iPhone 15 series’ USB-C port is a pivotal upgrade, providing not just faster charging but a plethora of new functionalities.
Whether you’re charging your Apple Watch on the fly or connecting to an external display, the iPhone 15 has you covered.
