That is basically what a protection diode is - except they do not use zener diodes. They have one diode connected to ground and one to VCC. If the voltage drops below ground, one diode conducts clamping the voltage to ~-0.7v. If the voltage increases beyond VCC, the other diode conducts and clamps the voltage at VCC+0.7v. This is effective when dissipating a small charge that could potentially be at a high voltage - think ESD. But if you have prolonged current the diode will blow and short.
So you have a short (blown diode) but you still have a significant amount of energy to dissipate. This results in a large current that will cause the diode to physically explode or possibly blow a trace. USB data lines typically use very thin traces and can not conduct much power. If a trace goes then USB is screwed but the rest of the computer will probably function correctly. If the diode explodes your protection is gone and the high voltage will now cause all sorts of damage.
Many people like Trump because he appears to be honest and genuine in what he says. This always made me laugh because I view him as the exact opposite. He says what he does to appeal to those whom he is speaking to. He is the least honest of all those who ran for the Republican nomination. A complete BS artist. I am willing to bet there is never a complete wall, Mexicans are not all deported, and Obamacare is not repealed - in name possibly but not in practice.
What is really depressing is that by spewing this crap, Trump was able to get sufficient votes to be elected.
Unfortunately every products costs the amount it costed t produce it plus the margin the producer wants to make. And that has nothing to do with what "the market" is willing to pay for it.
The margin the producer wants to make is based on the number of sales the producer wants and what "the market" is willing to pay. If sales are too low, the producer typically lowers the price. If sales are too high the producer either increases the price or increases production. Increasing production generally increases the unit cost over the short term so producers try to avoid this. But everything is based on what "the market" is willing to pay. Should production cost exceed what "the market" is willing to pay the producer ceases production and drops out of the market. So the production cost only determines if a product is produced in the first place.
You can safely forget about that after the calls are concluded
This is the point of encryption. They never have the unencrypted data so there is nothing to forget. If they have the information at any point in time, authorities produce a warrant requiring them to remember that information. This is why the metadata is fair game - the provider (Apple in this case) requires it to operate. But the data contents (email, documents, etc.) are never decrypted by the provider and remain secure.
Hell no. We are not talking about a 100W CPU/GPU, we are talking about a touch controller IC that uses almost no power. Thermal cycling due to regular use is not an issue. I am not saying that the solder connection is not to blame, just that the cause of the problem is not thermal cycling. If one is having repeated failures then they are obviously carrying the phone in such a way that it bends. The back pocket is the worst place to carry a phone, but the front pocket can also be bad. Some people do not even realize they are doing it. But one thing is certain, if you have 9 successive failures, it's you. Better odds of winning a lottery then having 9 successive failures -- or at least it is close.
I noticed that the iPhone 7 is not any thinner then the 6+. A tiny bit thicker even. This bodes well for the durability of the 7 so it is possible Apple learned from their mistake. Not that the 6+ is defective, but it could definitely be stronger.
