iPhone 15 Pro's Titanium Frame Makes It Feel Lighter Than Ever

The iPhone 15 Pro weighs less than the iPhone 14 Pro, with a 9% reduction from 206g to 187g due to the switch from stainless steel to titanium.
Analysis suggests the iPhone 15 Pro likely feels even lighter than its actual weight reduction because of a reduced moment of inertia.
Reducing mass at the phone's perimeter with titanium lowered moment of inertia more than just reducing total mass.
Estimates show moment of inertia reduced by 14-15% for iPhone 15 Pro, making it feel more agile.
Lower moment of inertia means the phone resists rotation less, amplifying the feeling of lightness.
