Similar story in Australia. Ultimately it doesn’t matter what a manufacturer says the official warranty is (for a consumer purchase), they can’t reduce the statutory rights to be less just because it’s in the warranty fine print. Though there’s also not an official list of “this device has a statutory warranty guaranteed of X years”, it’s left to be whatever is determined to be a reasonable expectation based on the price of the item, expected use, and a handful of other factors. I’ve not had to test it with an iPhone specifically, but I’d suspect it that a >$2000 device would be an easy case to make for a reasonable expectation of working beyond 2 years.
