17 Air - 2025 - 156.2mm x 74.7mm x 5.64mm, 165g

Sony Xperia Z2 - 2014 - 172mm x 266mm x 6.4 mm - 439g

Sony made nearly equally thin but lighter devices 11 years ago.

Again, not nearly the same screen size, so weight is irrelevant. But also, 439g? Wow! If that number wasn’t completely wrong, that would be impressive.

6.4mm is nowhere near as thin as 5.6mm, but I’m actually seeing 8.2mm for thickness on reliable websites, not 6.4mm: https://m.gsmarena.com/sony_xperia_z2-6144.php

Did an LLM hallucinate those specs that you quoted? I honestly don’t know how the thickness and weight you quoted could be that far off if you did the research yourself.

But, even if you were right, which you don’t seem to be, it’s all moot. No one is cross-shopping a 2014 phone to a 2025 phone. But even if they were, the real numbers speak for themselves.
