In September 2012, when Apple introduced the Lightning connector alongside the iPhone 5, it was hailed as a revolution in phone charging and data transfer. Fast forward a decade, and the world of smartphones has changed dramatically. So, it’s only natural to wonder: Will Apple stick with the tried-and-true Lightning port, or will they finally make the switch to the industry-standard USB Type-C?

The big news at Apple’s September 2023 event was the unveiling of the iPhone 15 and iPhone 15 Pro models, both sporting the USB Type-C port. While iPads and MacBooks had already embraced USB-C, this marks the first time Apple’s flagship iPhone series has joined the USB-C club. It’s a significant step, and it’s worth noting that Apple has also been working on a portless iPhone, proving they’re committed to innovation.

The Evolution of iPhone Connectors

Remember the old 30-pin “dock” connector that anchored iPod docking stations? That’s where it all began. Then came the Lightning connector in 2012, making charging and syncing more compact and efficient. With the iPhone 7, it even took on the role of an audio connector after the 3.5mm headphone jack’s removal.

Why the Delay in USB-C Adoption?

You might wonder why Apple took so long to adopt USB-C. The primary concern was electronic waste, as users would have to replace their Lightning cables and accessories. However, the European Union (EU) directive, set to begin in 2024, mandates that all devices sold in the region must feature USB Type-C exclusively. So, Apple had no choice but to comply, and they couldn’t have different ports for different regions.

Charging Speeds and USB-C Variations

While USB-C is a standard port, charging speeds vary depending on the generation. The iPhone 15 and iPhone 15 Plus sport a USB-C port based on USB Gen 2 specs, which may not sound too impressive, as USB 2.0 is an older technology with slower data transfer speeds (up to 480Mbps). Charging speeds for the iPhone 15 are expected to reach around 30 watts, but we’re eagerly awaiting more concrete results.

In contrast, the iPhone 15 Pro models use USB Gen 3, offering theoretical charging speeds of up to 100W and 10Gbps data transfers. While Apple doesn’t specify the exact generation, it aligns with at least USB 3.1 Gen 2, known as “SuperSpeed USB 10Gbps.”

However, rumors suggest that the iPhone 15 Pro models may only support a maximum charging rate of 35W, a slight increase from the previous model. The standard iPhone 15 might be limited to around 30W, requiring an Apple charging brick rated at 45W or higher to achieve these speeds.

What’s in the Box?

Apple surprised us by including an older USB 2.0 cable in the iPhone 15’s box instead of a USB Gen 3 cable for faster charging and data transfer. This move appears to contradict Apple’s commitment to reducing electronic waste, but the included cable is likely to be more durable than the Lightning counterpart.

Thunderbolt Support: Yes or No?

Unlike MacBook and iPad Pro models, the iPhone 15 Pro doesn’t seem to support Thunderbolt, which offers even faster charging and data transfer speeds. Although there’s an image hinting at Thunderbolt support, it’s not confirmed. To fast charge the iPhone 15, Apple’s $29 USB-C to USB-C cable should work, but for a more durable cable that also supports fast charging on other devices, you’ll need to invest at least $69 in a cable with Thunderbolt 4 support.

Apple is expected to introduce new accessories and cables for the iPhone 15 under its Made For iPhone (MFi) program. These options may offer a more budget-friendly alternative for faster charging.

While Thunderbolt support might be limited, all iPhone 15 models can project 4K video at 60Hz onto larger displays thanks to DisplayPort support. To make this happen, you can grab Apple’s $69 USB-C Digital AV Multiport Adapter. Alternatively, you can use a generic USB-C to HDMI adapter, but it might be limited to a 30Hz output on larger screens. If your TV or PC monitor supports DisplayPort functionality, consider a USB-C to DisplayPort cable.

For those who want to use their older Lightning cables or accessories, Apple offers a dongle priced at $29 — a solution that sparks its own debates.


With the iPhone 15 lineup’s shift to USB-C, Apple opens up new possibilities for connectivity and versatility. While there might be questions about charging speeds and included accessories, it’s clear that Apple is adapting to industry standards while keeping an eye on innovation. As we explore this USB-C journey further, users will uncover new opportunities and appreciate the enhanced capabilities of their beloved iPhones. So, get ready for a new era in iPhone connectivity!
