🔍 Overview: iPhone 17 vs iPhone 16 — What’s New in 2025?

Each year, Apple refines its design, cameras, and chip performance — but 2025 introduces one of the biggest upgrades for non-Pro iPhones in years.

Where the iPhone 16 built on reliability and minor improvements, the iPhone 17 finally receives Pro-level features, including:

• 120 Hz ProMotion on base model

• Brighter 6.3-inch OLED display

• A19 chip with AI-enhanced efficiency

• Dual 48 MP cameras (including ultra-wide)

• Upgraded 18 MP selfie camera

• Longer battery life

• Full Apple Intelligence access in iOS 26

For many users, this is the most meaningful upgrade cycle since the iPhone 13 era.

📱 Design & Display: The Biggest Upgrade Ever for Base iPhones

🔹 iPhone 17 Display Upgrades

The most dramatic improvement is the 120 Hz ProMotion refresh rate, which makes:

• Scrolling smoother

• Animations more fluid

• Games more responsive

• Everyday use far more premium

The iPhone 16’s 60 Hz display now looks noticeably outdated in comparison.

🔹 Screen Size Increase

• iPhone 17: 6.3-inch OLED

• iPhone 16: 6.1-inch OLED

A slightly bigger canvas makes content consumption, gaming, and typing more comfortable.

🔹 Design Refinement

Apple also introduced a sleeker camera island — now with a flattened plateau that reduces wobble on desks.
