Consumer Reports has a history of being hard on Apple. They famously refused to recommend the iPhone 4 because of a so-called “flawed” antenna design.

To test the Apple Watch, though, Consumer Reports is being harder on Apple than ever. They’ve run a gamut of torture tests on Apple’s new wearable to see just how hard the sapphire display actually is. Here’s a spoiler: You won’t be able to scratch it with anything short of a nuke. And even the Apple Watch Sport’s display is nearly unscratchable (although it can be cracked).

We’ve seen a lot of iPhone 6 torture tests in our day. But this guy dropping his iPhone 6 in a lava lamp has to be the grooviest.

I’ll be the first to admit I don’t really like it when people buy new iPhones just to destroy them on camera. It’s extraordinarily wasteful, not just of money but of the craftsmanship Apple puts into every device.

That said, even I have to admit this iPhone 6 torture test is awesome. Dude took an iPhone 6, froze it with liquid nitrogen, and then disintegrated it with a sledgehammer, like some cryogenic Thor.

Samsung has had to defend the Galaxy S4’s plastic form factor quite a bit since the device was announced back in March, and one of the ways it has done that is by touting the handsets durability. Plastic, Samsung claims, makes the device much more robust than competing smartphones because it bends and absorbs impact.

But as we suspected all along, aluminum is stronger. In a smartphone torture test performed by warranty provider SquareTrade, the Galaxy S4 fails to beat the iPhone 5 in drop tests, and even proved to be more fragile than its predecessor, the Galaxy S III.
