The iPhone 15 Pro’s Body Is Question of Distribution, Not Just Mass

Dr. Drang:

Finally, we come to Jason Snell’s surprise at how light the 15 Pro seemed when he played with it in the hands-on area. He mentioned this not only in his Macworld article, but also in the post-keynote episode of Upgrade. You wouldn’t expect a change from 206 g for the 14 Pro to 187 g for the 15 Pro would be that noticeable, but Greg Joswiak mentioned it in the keynote and Jason confirmed it. How can that be?

Drang questions if where the mass is distributed within the iPhone’s body could play a role in how much lighter the phone feels — apparently, more than its specs suggest. But most people upgrading to a new iPhone will probably have a phone much older than last year’s model. The iPhone 15 Pro weighs just two grams less than my 12 Pro, according to Apple’s spec sheet, which is a negligible difference. If the weight distribution plays a role, it is possible it will feel much lighter than it actually is.

The last time I can remember commentators remarking upon the weight savings of a new iPhone was with the iPhone 5, which was 112 grams compared to its predecessor’s 140 grams, and the iPhone 5 spread that weight across a taller body. The weight difference then was 28 grams compared to just 19 between the 14 Pro and 15 Pro.

Update: I feel obligated to mention that the iPhone 4S to iPhone 5 weight savings was the result of two materials changes: the iPhone 4S’ stainless steel band and back glass panel were both replaced with aluminum.
