I'm hearing a few inaccurate takes, so I'll attempt to clarify for people:
- The EU mandate is for devices introduced after the given date. Phones introduced before 2024 do not need to suddenly be redesigned to have USB-C to continue to be manufactured.
- It would be feasible that Apple would not need to upgrade to USB-C to release a new product until the 'iPhone 17', e.g. the September 2025 phone.
- They could also hypothetically just not release a lightning-based 'iPhone 17' in Europe, continuing to sell previous models for some period of time. It would be somewhat interesting to see what the market reaction to this would be (in particular, how much or little it would impact EU sales)
- The mandate is to support a standard set of chargers and cables, utilizing the USB-C style port and USB Power Delivery. There is no mandate that requires or forbids any other use of that port. For instance, Apple could decide not to support data at all outside of what is needed to negotiate power delivery.
- Continuing the prior point - there are rumors that if the base iPhone 15 has a USB-C port, that the Axx SoC used might not have support for USB 3.x speeds and it would be limited to USB 2.0 speeds.
- There is no mandate to eliminate other charging-capable ports as long as USB-C charging is one of the options. It is unlikely Apple would release a phone with both USB-C and lightning ports for the EU market. However, when USB-C is mandated for new laptops, this will not require the elimination of the magnetic MagSafe port. Likewise, it shouldn't impact the iPad Pro and its Smart Connector.
- USB4 is a different protocol than you would expect from prior versions of USB. The 4 is part of the name and not a version number. USB4 1.0 will eventually be replaced by a USB4 2.0.
- A USB4 device AFAIK does not have to support USB 3.x and earlier.
- Thunderbolt4 is not really a separate protocol anymore, but a licensed certification tied to a set of higher minimum requirements on top of USB4 1.0 (and Thunderbolt 3, and USB 3.2). You'll never buy a Thunderbolt4-certified cable then find out it can only support USB 2.0 speeds.
- Because of this, a device could meet all the requirements for Thunderbolt 4, but decide not to use the brand or pay for certification/licensing.
- So far, Apple has only used the Thunderbolt 4 mark on the Mac Studio.
- Thunderbolt 5 will likewise be USB4 2.0 with extra requirements, certification, and licensing terms/fees on top.
