A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

The future of mobile devices? (infosec.pub)

I wonder if the charging port on mobile devices will go the way of the 3.5mm jack and be replaced with Qi and other wireless charging protocols. I also wonder if we will be forced into Bluetooth for all extension devices we used to connect to usb-c.

The EU does not require a charging port, it only says that if you have a charging port it must be USB-C.

By the end of 2024, all mobile phones, tablets and cameras sold in the EU will have to be equipped with a USB Type-C charging port.

Idk seems like the port is a requirement.

Nope.

Look at the actual directive , not some press release. Note that this is an older directive, but the common charger directive only describes the changes that need to be made to the earlier directive. The first link is to the latest updated version of that directive.

I quote (emphasis mine):

In so far as they are capable of being recharged by means of wired charging, the categories or classes of radio equipment referred to in point 1 of this Part shall:

2.1. be equipped with the USB Type-C receptacle, as described in the standard (…)

2.2. be capable of being charged with cables which comply with the standard (…)

At the moment the directive does not prescribe a universal standard for wireless charging, but does reserve the right to do so in the future. (At the moment it doesn’t seen necessary as everyone seems to be adopting QI)

Thanks for linking the actual directive.

To be fair: it wasn't "some press release" - it was the official statement on the matter by Parliament.

Quoting from the directive:

When preparing the delegated acts referred to in this Article with respect to radio equipment capable of being recharged by means of wired charging, as well as with respect to radio equipment capable of being recharged by means other than wired charging, the Commission shall take into account the degree of market acceptance of the technical specifications under consideration, the resulting consumer convenience and the extent of the reduction of environmental waste and market fragmentation that can be expected from such technical specifications.

Given that they're focused on reduction of waste and reduction of market fragmentation there's definitely a question mark over only QI based charging. I think they've left themselves significant latitude to smack down any attempts to fully go to wireless charging without a port.

Remains to be seen if they will.

I don't see how you can get that from the text. The way I read it, wired and wireless charging are separate. There is nothing in the directive that mandates one should be used over the other. They explicitly require USB-C for wired charging, but do not put any requirements on wireless, as there doesn't seem to be any significant fragmentation on the wireless side (i.e. no need to enforce a standard if everyone already agrees on a standard).

My quote explicitly ties wired and wireless charging together into the document. They left it open in saying "we're not establishing any rules yet but these go hand in hand and we'll immediately start looking at wireless charging in the context of e-waste".

It just says they are keeping an eye on developments in both wireless and wired charging standards. Not a word on requiring either on any device.
