Possibly not related, but my past two Samsungs have had this feature and it drives me crazy. Usually they seem to trigger when using non standard cords and from 0% battery life. This means that I get a very loud warning sound triggering when trying to charge my phone from a battery pack or borrowing someone's cord. Oddly, charging when on (ie not completely dead), this feature doesn't trigger the alarm. I really disl…

This seems like fake outrage at a restriction that exists only in a hypothetical that nobody on earth would ever implement if for no other reason than the fact that it would be incredibly hard and complicated. If some future despot actually wanted to forbid dirty power wouldn't they just do that instead of making your phone not charge?
A lot of people said the same things about DRM and many other predictions that turned out to be true.
(Also, your basic claim is false. Who ever said DRM was never going to exist? That would have been an absurd claim to make at any time. Long before personal computers or the internet, the music industry was already trying to make cassette tapes illegal because they facilitated home recording. It was a no-brainer that they would attempt to extend this same control into the digital realm)
I wonder if Apple will ever make a waterproof laptop or tablet. It seems like they could easily make the macbook air waterproof at this point, if they were so inclined. What do people who want use their macs out in the field do?
Making the ports waterproof would be pretty easy, since they can do that on iPhones. But what about the ventilation areas? That's much trickier, I'd think. Making a waterproof iPad should be trivial since it has the same ports as an iPhone.
iPhones are not waterproof, they're IP68 water resistant. Apple even describes the port as being a liquid egress (and thus ingress) point in their public "oops I dunked my phone in water" support documentation.
Dry your iPhone:
1. Tap your iPhone gently against your hand with the connector facing down to remove excess liquid. Leave your iPhone in a dry area with some airflow

MacBook Airs no longer have ventilation

That’s honestly kind of crazy. It’s only an IP68 rating. It’s meant for prevention of damage during quick submersion accidents, not snorkeling. >the waterproof aspect of modern phones is one of my absolute favorite developments. IP68 is water resistant, not waterproof.
I think water resistant is underselling what IP68 is a bit. The test to pass ip68 is to completely submerge the device in water up to 30 minutes. Sure that’s not water proof, but when people think water resistant they probably think “should survive water getting spilled nearby”, which is a level below “able to be completely submerged in water for up to a half hour”. For most cases where it matters the device is water…
This is a feature of newer usb-c pd chipsets. See, e.g., https://www.ti.com/product/TPS25751 in the features section. Apple has historically used TI chipsets for their USB power controllers. The feature likely comes from this.
How it works (on page 52): "The TPS25751 supports liquid detection by measuring the voltage level across the SBU pins of the Type-C connector. When a short occurs across the SBU pins to another Type-C pin(s), the TPS25751 takes action to protect the the Type-C port by disabling the power paths and notifies the embedded controller when applicable. Once liquid has been detected, the TPS25751 continuously monitors the S…
I wonder how reliable this will be. Back in the summer, my mom plugged her iPhone in to charge, and it gave a warning saying that it couldn't charge because there was liquid in the charging port. However, the port was bone-dry, and there was no liquid anywhere near the phone. It turned out that the charger didn't like the extension cord that it was plugged into. I took the extension cord away, and the phone started c…

Dumb question: wouldn't non-conductive liquids be harmless? i.e., the USB port can in theory work even if it is immersed in some non-conductive liquid, no?
