iPhone 15 vs iPhone 16: What’s Really Changed?

Apple continues its tradition of annual iPhone upgrades with the launch of the iPhone 16 series. While the iPhone 15 introduced notable improvements like the Dynamic Island across all models and a switch to USB-C, the iPhone 16 focuses on refining performance, enhancing camera capabilities, and introducing AI-driven features. At first glance, both phones may look similar, but under the hood, the iPhone 16 offers meaningful upgrades—especially for power users and content creators.

One of the biggest changes is the introduction of the new A18 chip in the iPhone 16 lineup, delivering faster processing and improved energy efficiency. Apple has also made subtle tweaks to the display brightness, battery optimization, and rear camera system—especially in the Pro models, which may include a dedicated “Capture Button” for improved photography control. If you’re wondering whether it’s worth upgrading, the table below offers a side-by-side comparison to help you decide.
