In the run up to the launch of the 12 models, many were concerned at the physical attributes. Comparing the existing Samsung phone against a 12, we can see:
Samsung Fold 2
Dimension (HxWxD, mm)
160.9 x 117.9 x 6.9
Dimension when folded (HxWxD, mm)
160.9 x 62.8 x 15.7-17.1
Weight (g)
276
Apple iPhone 12 Pro
Dimension (HxWxD, mm)
146.7 x 71.5 x 7.4
Weight (g)
187
1) Fold is 14.2 mm taller.
2) 12 Pro is 8.7 mm wider.
3) Open, the Fold manages to be 0.5 mm thinner, but folded that changes to being 8.3 to 9.7 mm thicker - more than double.
4) Fold is 89 grams heavier.
To me, they make the Fold unattractive. Too tall for my pockets (the 12 Pro is just about as tall as I am comfortable with.)
The extra width of the 12 Pro allows for a slightly wider screen and still fits in my pockets.
The thickness of the Fold is a total killer. With a case, my 12 Pro is at the limit for my pockets. The Fold would be unbearable.
Many criticised the 12 Pro for being too heavy (being 25 grams more than the 12 - and even that being called out as too heavy by some). I find the 12 Pro acceptable but wouldn't want any more weight. The Fold is almost fifty percent heavier than the 12 Pro! 70% more than the 12.
Obviously any potential foldable iPhone could be a very different design, and would be exploiting all sorts of technological enhancements. But do we really expect sufficient changes in the next two years?
