The breakability of the new iPhone 6s and iPhone 6s Plus has been put to the test by MMA fighter Luke Rockhold.

In a demonstration for gadget insurer SquareTrade, the world's No. 1-ranked middleweight fighter compared the strength of Apple's new designs against last year's models.

Using his famed "Rockhold Submission" as well as a devastating roundhouse kick, the former Strikeforce middleweight champion showed the devices no mercy.

While none of them were able to survive Rockhold's attack for long, the new iPhone 6s Plus did provide significantly more resistance.

So if you needed to see a UFC fighter brutally destroy Apple's new device before you were totally convinced, there you go.
