Apple Reportedly Planning to Limit iPhone 15's USB-C Port in the Same Way as Lightning

The iPhone 15 and ‌iPhone 15‌ Pro's USB-C port and accompanying charging cables will feature a Lightning-like authenticator chip, potentially limiting their functionality with Apple-unapproved accessories, a rumor shared on Weibo suggests.


The rumor declares that Apple has developed its own variant of USB-C for this year's ‌iPhone 15‌ lineup and comes from a user who claims to be an integrated circuit expert with 25 years of experience working on Intel's Pentium processors.

Integrated circuit (IC) interfaces are semiconductor chips used to manage the sharing of information between devices. Since their introduction in 2012, first-party and MFi-certified Lightning ports and connectors contain a small IC that confirms the authenticity of the parts involved in the connection. Non-MFi-certified third-party charging cables, for example, do not feature this chip, often leading to "This accessory is not supported" warnings on connected Apple devices.

The authenticator chip allows Apple to encourage customers to buy genuine iPhone peripherals and receive a commission on MFi-certified accessories, but it also allows Apple to tackle counterfeit and potentially dangerous accessories.

The latest rumor seems to suggest that Apple has developed a similar custom IC for the USB-C ports on the ‌iPhone 15‌ and ‌iPhone 15‌ Pro, and presumably its charging cables. As well as the ‌iPhone 15‌ lineup, the new IC is apparently destined for new MFi-certified peripherals.

It is worth noting that the USB-C interface currently used by Apple in the 10th-generation iPad, iPad mini, iPad Air, and iPad Pro, do not contain an IC chip for authentication, meaning that this would be a first for ports of this kind offered by the company.

It is unclear if this addition could have any major implications for the functionality of the new devices, but it is possible that Apple could limit features like fast charging and high-speed data transfer to Apple and MFi-certified cables.

According to Apple analyst Ming-Chi Kuo, the USB-C port on the ‌iPhone 15‌ and ‌iPhone 15‌ Plus will remain limited to USB 2.0 speeds – the same as Lightning. Only the ‌iPhone 15‌ Pro and ‌iPhone 15‌ Pro Max models will apparently get faster charging speeds. As a result, the only major difference between Lightning and USB-C on the standard ‌iPhone 15‌ models could simply be the physical shape of the connector.

The report is particularly believable since this would effectively mirror the split between the entry-level ‌iPad‌ and the ‌iPad Pro‌. While both ‌iPad‌ models feature a USB-C port, the 10th-generation ‌iPad‌ is limited to USB 2.0 speeds of up to 480 Mbps, while the ‌iPad Pro‌ offers fully fledged Thunderbolt speeds up to 40 Gbps.

The hidden cost of food delivery

Noah Lichtenstein Contributor Share on Twitter Noah Lichtenstein is the founder and managing partner of Crossover , a diversified private technology fund backed by institutional investors, technology execs and professional athletes and entertainers. More posts by this contributor What Studying Students Teaches Us About Great Apps I’ll admit it: When it comes to food, I’m lazy. There are dozens of great dining options within a few blocks of my home, yet I still end up ordering food through delivery apps four or five times per week. With the growing coronavirus pandemic closing restaurants and consumers self-isolating, it is likely we will see a spike in food delivery much like the 20% jump China reported during the peak of its crisis. With the food delivery sector rocketing toward a projected $365 billion by the end of the decade, I’m clearly not the only one turning to delivery apps even before the pandemic hit. Thanks to technology (and VC funding) we can get a ri

Technics EAH-AZ60 review: Contending in stunning fashion

Technics serves notice that everyone should notice these earbuds. Technics ventured into the wireless earbuds category to go after the big dogs in the race. Think of the likes of Sony, Bose, and Sennheiser on sound quality, as well as the best you can find on design and functionality. It's a combination that comes at a price, but if done right, it gets easier to justify spending more. That's the case Technics makes with its EAH-Z60 earbuds. Its newest pair aims to take what the company has done in the past and make it even better. The results are easy to like and are significant enough to consider them as serious contenders.

iOS 14 Favorites Widget: How to Make a Replacement With Shortcuts

In iOS 14 , Apple overhauled widgets and introduced an option for adding ‌widgets‌ to the Home Screen , but in the process, a well-loved Favorites widget that existed in iOS 13 was removed. The Favorites widget let users set certain contacts and contact methods as favorites that were easily accessible, so you could, for example, add a favorite option for messaging Eric or calling Dan, with those actions executed with a tap. Why the Favorites widget was removed is a mystery and it could be a simple oversight with Apple planning to reintroduce it later, but for now, those who relied on the widget can recreate its functionality with Shortcuts. It takes some effort, but it may be worth the time investment if you often relied on your Favorites. Creating a Favorites Shortcut Making a shortcut that replicates the behavior of the Favorites widget isn't too tough, but if you want multiple favorite options, you'll need to create a separate shortcut for each one in the Shortcuts
