I haven't thought about it as much as I have about sizes, but you do have an interesting point to ponder. I can only offer an explanation, but no consolation:
I guess electronics has gotten denser, and density for the same volume is what quite literally translates to larger weight. The density thing is because they're able to cram more electronics, as our fabrication technology inches forward (i.e. Intel/TSMC/Nvidia/etc trying to break the 1nm barrier for transistors).
Remember the old Nokia phones, where the plastic shell likely amounted to as much volume that a modern phone instead dedicates to the entire front camera device? The latter will weigh much more than the plastic, for the same volume. Now apply that to _every_ component in the modern phone, and the difference is multiplicative -- there's just more features in every cubic millimeter of the phone today. No wonder it's getting heavier.
