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.

What do you mean? I have 3 connected to mine

Do you have to use that displaylink software with terrible framerate and latency compared to native? I tried to get 3 monitors working on a work Mac with a new triple DisplayPort dock and had a terrible time, I went back to my Linux desktop since I can easily get smooth 165hz native performance on three monitors

I have a 4K monitor connected via usb3 displaylink and it gets 60fps.

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…

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?

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 SBU voltage. During the SBU voltage monitoring, if the liquid/short is no longer present the TPS25751 takes action to return to normal operation."

In other words, it's not actually detecting "liquids" but more of any conductive short. Non-conductive liquids, like oils and many other petroleum products, won't be detected.

My iPhone 13 mini was IP rated and died after the first dunk. All of my Android Galaxy SXX phones have survived tons worse.. repeatedly. I treat the new iPhone I had to buy as if it were made of porous glass. Edit: Thanks everyone for the additional data points!

My 13 Pro has drowned at least 3 or 4 times, still working. Also worth mentioning it's been case free and survived countless drops. I don't understand why people put cases anymore.

My 14 Pro's back, plus one camera, completely shattered in one drop. It's luck of the draw (or nearly indistinguishable from it). I still go caseless, though.

A lot of people said the same things about DRM and many other predictions that turned out to be true.

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…

Funnily enough, my Sony Xperia 5 III does this if I plug in a Thunderbolt 4 cable. Charges extra-slowly, and complains about liquid in the USB port.

It's probably a not-entirely-compliant USB implementation on the phone.

They'll save money on warranty repairs in that case - by blaming your mom for a water spill - so it'll all work out for them.

It's not even a new trick, some scammy repair companies here in Europe loved to claim water damage to avoid warranty repairs.

I wonder the same. We used to take cell phones not being waterproof as standard. Now everybody expects them to be waterproof. The idea that is single spilled coffee can cause $1000 of damage or more to a laptop is ridiculous.

Spill proof should be possible reasonably. Think pad used to have channels for water drainage not sure they still have them. Dunking proof laptop would be possible but tradeoff not worth it.
