The knife test is basically ASMR horror at this point, but was originally to identify plastic vs metal in frames and buttons, and also plastic vs glass on cam lenses.

The lighter test was originally to identify lcd vs led as they behave differently, but afaik nobody is even doing lcd anymore...

The point is a destructive test to failure.

Watch the new iphone tests and you will see the point.

The phone still works at the end.

>Not sure if I see the point of using a craft knife to scratch the case though. Nor the point of using a lighter to kill pixels on the screen. More for the sheer horror of it than anything.

His videos of scratching up phones with razor knifes and breaking them and such get views. It's a bit of a shame, because his other content is actually pretty good, but he built his channel doing those sorts of videos and they continue to pay the bills.

A cheap lighter if it cracks could potentially cause a small fire. But still it would be astronomically unlikely that your phone is also present with it and then even more unlikely it burns long enough to cause damage without one stopping it.

It would make a lot more sense if it were keys or an electrical plug's blades or other objects likely to be found in a pocket/bag alongside my phone.

the knife is a hardness test - shows you it's not stainless steel in the frame

7:20 for anyone who just wants to see the failure. I have to respect someone committed to the content: Not only does he flip it with his bare hands while it's still sizzling, he makes sure to hover over it while the plume of battery smoke wafts up lol.

scratches aluminium with knife - me: "stop, stop!"

pours dirt and makes crunchy hinge noises - me: "stop, stop!"

holds lighter to screens - me: "stop, stop!"

bends phone backwards, it breaks at the antenna line - me: "stop, stop!"

smoke comes out - me: "pretty... I wonder when the smoke detector is going to... ah about 20s"

There's nothing like getting your product problem exposed on a channel with 9+ million subscribers...

Watch his test of the new apple phones, he tortures the device far beyond this test and it still works.

A google pixel going up in smoke because you bent it by hand is completely unacceptable.

I suspect we aren't too far from the FAA wanting to certify every battery bank. I don't blame them either.

The entire world would come to a stop if you could no longer transport LiPos on a plane. International travel will no longer be possible as smartphones are necessary for everything these days.

I know you're joking but truth be told, he did fold it wrong.
