I always wondered why it is possible to simply switch off a stolen phone. If it would require the PIN to switch it off you have the remaining battery time to find your phone.

It would be better if iPhones embedded the airtag tech so on a flat battery, you would still have about a year of tracking time via airtags. Also the power button hold overrides the OS so you can shut down a frozen OS

Would love this on AirPods too

Even if there were a PIN code to power off regularly, you could always force cut the power (like pressing power for 10s on a computer). I think this has to be possible by law for emergencies.

Requiring a pin to switch it off might just cause someone to invent a device that can be inserted into the Lightning port to cause a shutdown without affecting the for-parts resale value of the phone. (For example, the device could cause a short circuit or apply an unexpected voltage, causing the power controller to shut off power to the device.) If the attacker has physical access, there's not much you can do.

Here's an easier way - dump the phone in a freezer or ice pack.
