If I understood this correctly, this is based on a higher (but unknown to consumers?) chance that the Galaxy Note 7 's battery could explode during flight and catch fire. Then, what would be considered a chance high enough that a laptop battery's explosion would not be a concern? Would it be safer to lock these phones into an explosion-proof box before they onboard the flight?

The risk is only while the Samsung device is charging (as I recall?). As for other devices, I suppose they could issue the warning "please do not hit your device with a hammer during flight". Fun fact I read recently: more than a million people are in the air at any one time, globally. If laptop batteries exploded even rarely, we'd hear about it.

It depends on the mode of failure, but these problems happen when a battery is stressed. Charging or discharging at a high rate especially with high temperatures and during/after physical stress can cause runaways.

Protection circuitry is supposed to prevent runaways, something is obviously failing. It could be an overheating component or faulty high voltage protection circuits or simply just bad thermal design.

This is actually my #1 fear in flying in 2016. Some rough baggage packing under the plane that damages a laptop battery in the gate checked bag. Every time I fly I watch people gate check bags with laptops and more even after the announcement to "remove all lithium batteries & electronics". I wish more people understood how dangerous this could be and would take 3 minutes to take electronics out and carry them on boa…

It seems unwise to gate-check a bag with a laptop anyway, given the way the luggage handlers throw bags around. Gate-checking a roller board suitcase with clothing is one thing, but I wouldn't check anything fragile or particularly expensive.

Is this a Samsung-specific problem, or is it more generally, a lithium ion battery problem (the regulations have always been in place for lion batteries on planes)?

I suspect it's the latter -- in which case, it's pretty unfair to single out Samsung.

On another note, I've always felt paranoid about keeping my phone in my pocket or having my laptop on my lap, especially if it starts to heat up. I might as well stick an M-80 in my pocket right next to my crotch.

The Galaxy Note 7 is being recalled over fires that have actually occurred.

So I don't think it's unfair to single them out in this case.

A Samsung Galaxy Note 7 problem to be even more specific.
