On the other hand, when my iPhone suddenly would connect with a caller, but neither party could hear the other, redialing didn't help, turning it off/on didn't work, I remembered the ancient trick of "cold boot". Which resolved the problem.

You put an iPhone in the freezer and booted it, and that fixed it? Wow. I thought that was just for saving spinning disk drives and preserving the contents of RAM for an attack.

A cold boot means shut off all power to the device. The normal "off" button the iPhone puts it in standby mode, not off. This is so it can still listen for calls.

I tried to power off an iPhone today for 5 minutes, failed, and just gave up. Why Apple, why would you make this simple action so damn obscure.

My iPhone 10 locked up hard a few days and I couldn’t get it to turn off using the standard method.

After some digging, I found a new trick that I guess is implemented at a lower level: press and release volume up, then volume volume down, then press and hold the main button until it powers off.

Wait, is it not press-and-hold power like on Android?

No, on the newer iPhones press and hold simply brings up Siri. Gotta press and hold main button and either volume button simultaneously. If that doesn’t work you should be able to use the trick I describe above.

you have to press the "power" button and a volume button afaik
