It's crazy how many people complain about the weight.
From Apple's comparison chart on its website:
Weight 7.19 ounces (204 grams) 13 Pro
Weight 6.66 ounces (189 grams) 12 Pro
Weight 7.13 ounces (202 grams) 8 Plus
Weight 6.14 ounces (174 grams) 13
Weight 5.22 ounces (148 grams) 8
Appears that it's the size that's throwing people off.
Maybe it's the weight distribution that's affecting the perception of the iPhone's weight.
Going from a smaller iPhone (SE/mini) to a larger iPhone (Max) is where people can tell the difference, mainly due to the bigger size; ~1~2 Ounce variance.
Going from a similar large iPhone (Plus) to another large iPhone (Max), the weight difference is negligible and immaterial; ~1 Ounce variance.
If anyone can truly feel the weight difference of an additional ounce or so and complains, one needs to exercise.
Going from an older Plus Model (6S Plus then 8 Plus), it was refreshing to downsize to the 13 Pro as it was less bulky. Have to check my pockets many times just to make sure it was there. ?.
Didn't have to do that before as the Plus models stuck out and barely fit in many pockets, sometimes falling out. Thank goodness all the iPhones were/are in cases.
13 Pro Max vs 13 [Pro] dimensions, respectively, from Apple's website:
Height 6.33 inches (160.8 mm)
Height 5.78 inches (146.7 mm)
Variance: 0.55 inches
Width 3.07 inches (78.1 mm)
Width 2.82 inches (71.5 mm)
Variance: 0.25 inches
Depth 0.30 inch (7.65 mm)
Depth 0.30 inch (7.65 mm)
Same
For those that want the extra screen space, the height & width differences seem negligible unless you're truly want the extra space along with the bulkiness esp. for gaming and video/photo- graphy.
To each their own!
The irony is that when the Plus sizes first came out, lots of people bashed Apple for the (then) huge sizes & supposedly following the larger Samsung smartphones (i.e. Samsung Note's size caused stir back then with other Android smartphones following suit).
Now, lots of people want the larger iPhone size, yet demand is still there for the smaller, regular and mini iPhone sizes.
Apple can't please everyone but is trying with 4 sizes now yet people still find something, anything to complain about.
