That's because it's a warranty - it covers faults, not damages. If you want apple to fork out for a new one because you've dived into the sea with the phone on an armband then you need to pony up for Apple Care +

If you sell a device as waterproof and then it gets damaged by water, that’s obviously a fault: it wasn’t waterproof like it was meant to be.

Who is selling a waterproof phone. Because it’s not Apple.

Sony phones with headphone jacks, ten years ago were capable of all waterproof things you wanted to do. It's been a massive gaslighting campaign.

Same thing with the Samsung S5 from 2014. IP67 waterproof with headphone jack and removable battery.

I really am super pissed that we let go of removable batteries

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…

I had my S22 upside down in my pocket and happened to splash water directly into the USB port and nowhere else. The precision was honestly kind of impressive. I only knew about it because my phone freaked out. I let it dry overnight rather than charge it, and everything has been good since then.

FWIW, you can still charge it wirelessly.

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.

The binary is at "/System/Library/CoreServices/liquiddetectiond". I took a quick look at disassembly, it has some functions for getting voltage, an amusingly named selector called "setIsWet". There's an "AnalyticsSendEvent" in there (and some corresponding obj-c methods). Maybe marcan will do a deeper disassembly one day. There's some reference to TI stuff in the selector names so you're probably right about that.

But you still can’t connect two monitors.

Nope you can connect four: https://support.apple.com/en-gb/HT213503

It's 2023 and finally can connect more then one... what is their justification for not being able to do this before.

We didn't let them go, they were taken from us by force

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?

> Dumb question: wouldn't non-conductive liquids be harmless? Mostly yes, except for things like concentrated sulfuric acid which is highly corrosive but a bad conductor.

Agree: bad conductor - https://chemistry.stackexchange.com/questions/153107/why-doe...

I'll keep that in mind.

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…

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.

The "liquid" detection just measures conductivity between certain pins that should not have any. Sounds like the extension cable was damaged/faulty?
