The iPhone 15 and iPhone 15 Pro models feature the same overall design as the iPhone 14 with flat sides. However, they include tweaks like more rounded edges, and the new Pro models are made with titanium frames.

The iPhone 15 Pro and Pro Max are barely thicker than their predecessors at 0.32 inches (8.25 mm) and the iPhone 15 and 15 Plus are the same thickness as the 14 and 14 Plus at 0.31 inches (7.8 mm).

And with the switch to titanium, the 15 Pro models are 8 to 9% lighter than the 14 Pro devices. While earlier rumors suggested we could see battery capacity increases of 10% and higher, it turns out the iPhone 15 lineup has almost identical mAh capacities – and the exact same battery life ratings as the 14 lineup as measured by Apple.
