The latest iPhone models iPhone 15 and iPhone 15 Pro are equipped with USB-C charging capabilities, allowing for a significant improvement in charging speeds. Using a USB-C cable and Apple’s standard 20W USB-C charger, these devices can be charged from 0 to 100% in under two hours.
While the maximum charging speed via the USB-C port remains the same as the previous iPhone 14 series, which could also charge via Lightning at the same speed, the introduction of USB-C brings a notable difference. The iPhone 15 is now capable of delivering up to 4.5 watts of power to accessories via USB-C, compared to the significantly lower maximum power of 0.3 watts via Lightning on previous iPhones.
This increase in performance opens up new possibilities for iPhone accessories as devices can now be powered directly from the host iPhone itself. For example, bus-powered USB-C portable hard drives can be connected directly to the iPhone to serve as external storage. Additionally, the iPhone 15 Pro’s USB-C port is USB 3, allowing data transfer speeds of up to 10Gbps.
During Apple’s keynote, it was noted that users can even charge their AirPods or Apple Watch in emergency situations by connecting them to the iPhone 15 with a USB-C charging cable.
With the introduction of USB-C charging capabilities and increased power delivery for accessories, iPhone 15 and iPhone 15 Pro offer users greater convenience and flexibility. It will be interesting to see how the world of iPhone accessories expands with these new features.
