Pixel user here, but I feel the same way. The fact that my phones are getting heavier instead of lighter seems counterintuitive on its face.
Pixel 1 (143g)
Pixel 3 (148g)
Pixel 5 (151g)
Pixel 8 (187g)
Pixel 9 Pro (198g)
Of course the displays of these models get bigger which presumably contributes to the weight increase. But still, you'd think parts get lighter over time, not heavier.
