The camera is taken right up to the bore. You’re right, it wouldn’t be 3T, but it’s getting close and it’s way inside the 5g line. The iPhones I have seen go in have not had a lot of pull and can be held, even close to the bore (less than 1m). The service instructions require photographs of various component - I watched a cold head get photographed recently. I’ve also seen an engineer take a laptop pretty close. It t…

Ah, service tech makes sense. Most others aren't going see anything interesting in the photo that close. Laptop is pretty crazy, what where they (not) thinking? I guess was imagining "normal" camera not phone, but you are right that modern attempts to make phones light have removed most of the magnetic material. It doesn't take much to make it a problem (e.g. steel screws). Typical rooms are going to over 20g acceler…

Absolutely. The engineer with the laptop had a brain fade - his area was usually CT.

As magnets have got better control over their fringe fields, the issue has got worse. The field goes from nothing to 3T in a very short distance, so 10+ T/m rate of change is not uncommon.

It's very dangerous especially in France due to old ordinance. Google magnet fishing

"Ordinance" is legislation. "Ordnance" is the explosive stuff. Old ordinance can also be troublesome, but is rarely deadly.

And just to confuse things a little more we have in the UK:

Which is not a survey of explosive devices.

That seems like pretty bad luck! In the early months of the pandemic I washed my iPhone 11 daily with no ill effects.

It was likely damaged. A fall, for instance, can damage a smartphone enough to break its seal while being almost imperceptible to humans. Making electronics water resistant is always a very tricky endeavor.

Oh probably. But a lot of people drop their phone once in a while. I just read about a guy dropping it into a Berlin canal! The thing is that if it dropped once you can’t rely on your phone being waterproof anymore.

iPhones 7 through 11 felt increasingly easy to destroy with the slightest touch - not so the iPhone 12.

Interesting. I skipped from an iPhone 6 to an 11 Pro, and when I pick up my old 6 now it is both so thin and light as to feel very fragile, whereas the 11 Pro has a dense, hefty, solid feel in comparison. I have briefly used someone else's iPhone 12 and it didn't feel any different from my 11 Pro, to me. YMMV and all that.

> I would have just given up and bought a new iPhone If people didn't already realize that most of people hanging around on HN have the top 10% of the world's wealth, this made things clearer than ever (the phone in question costs around 1000 EUR) Makes all the conversations around finance here make so much more sense.

If you are making €200,000 per year, your time is worth around €100 per hour. Thus if this is going to take more than 10 hours, it is not worth your time.

That's very flawed and naive method for measuring value of one's time.

This is, of course, only true if you can bill someone for those ten hours.

And even if you could, you should be billing them at a substantially higher rate than your normal salary already consuming your full-time bandwidth. These extra hours are precious and increasingly scarce bandwidth for self, and fast overlap into exceedingly inconvenient territory.

How much volume of air must be inside a standard phone these days to make it buoyant?

An iPhone 12 weighs 164g [1], so, through the magic of the metric system, it needs to displace a minimum of 164ml of water to float. The iPhone has an external volume of 14.67cm * 7.15cm * 0.74cm = 77.62cm^3 = 77.62ml. So it would need to be about 2x the volume to float. [1] https://www.apple.com/iphone-12/specs/

Time to roll back this innovation and release the new iphone with 2x volume so that it'd float.
