Design and Display Comparison: Difference Between iPhone 18 Pro and iPhone 17 Pro
With no major changes in display and design, the iPhone 18 Pro, however, is ready to introduce advanced features and techniques.
1. iPhone 18 Pro vs iPhone 17 Pro Display
| Display Features At A Glance | ||
|---|---|---|
| Specifications | iPhone 18 Pro | iPhone 17 Pro |
| Display Size | 6.3-inch | 6.3-inch |
| Live Activities | 3 Live Activities | 2 Live Activities |
| Face ID cutout | Smaller | Usual |
The iPhone 18 Pro retains almost all the same display features as the iPhone 17 Pro, including:
- 6.3-inch Super Retina XDR display
- Wide Colour, HDR, and True Tone
- ProMotion Technology With Adaptive Refresh Rates Up to 120 Hz
- 2 Million-to-1 Contrast Ratio
- Typical 1000 nits brightness, 1600 nits for HDR content, and 3,000 nits peak outdoor brightness.
One of the major changes in the iPhone 18 Pro is the “Dynamic Island”. Apple has engineered the camera to take up less space; that is, the Dynamic Island is expected to be reduced by 30-35% and display up to 3 live activities instead of 2 in the iPhone 17 Pro. However, it retains full capability for secure face unlocking, payments, and sign-ins.
2. iPhone 18 Pro vs iPhone 17 Pro design
Similar to the iPhone 17 Pro, iPhone 18 Pro retains the camera plateau on the back of the phone and uses aluminium instead of titanium for improved heat dissipation.
However, the Cosmic Orange colour of the iPhone 17 Pro will be replaced by more sophisticated colours of the iPhone 18 Pro, including:
- Burgundy Red
- Glacier Blue
- Silver
- Deep Black
Key Takeaway:
Which iPhone Pro has Better Design: iPhone 17 Pro Vs iPhone 18 Pro
There are NO major changes in design and display. The only change in the iPhone 18 Pro is the shrinkage of the Dynamic Island and the new colours, such as Burgundy Red, Glacier Blue, Black, and Silver.
Performance Comparison: A20 Pro Vs A19 Pro
The iPhone 17 Pro runs on Apple’s A19 Pro chip, featuring a 6-core CPU, 6-core GPU, and 16-core Neural Engine. It also supports hardware-accelerated ray tracing, which is designed to handle demanding gaming, video editing, and AI workloads. The A19 Pro chip is ideal when you:
- Record 4K videos and edit them on the device
- Play demanding games
- Run heavy local AI tools
The iPhone 18 is expected to introduce the A20 Pro chip, the first Apple chip manufactured using TSMC’s 2nm technology. It is believed to be 18% faster and 30% more power-efficient than the A19 Pro. It is expected to feature a seven-core GPU, up from six cores in the A19 Pro, offering strong graphics performance.
The A20 Pro is also expected to adopt TSMC’s Wafer-Level Multi-Chip Module (WMCM) packaging, which shortens the data paths and reduces thermal coupling between CPU and memory, helping improve heat management.
Key Takeaway:
The iPhone 18 Pro is a clear winner in terms of better performance because of its new A20 chip, which is faster and power-efficient.
Camera Comparison: iPhone 18 Pro Vs iPhone 17 Pro
| Camera Difference At A Glance | ||
|---|---|---|
| Specifications | iPhone 18 Pro | iPhone 17 Pro |
| Camera Specs | 48 MP Fusion Main with Variable aperture, 48 MP ultra-wide, 48 MP telephoto with 8x optical-quality zoom, camera control, 18 MP Centre Stage | 48 MP Fusion Main, 48 MP ultra-wide, 48 MP telephoto with 8x optical-quality zoom, camera control, 18 MP Centre Stage |
The iPhone 17 Pro camera features a 48 MP Pro Fusion triple-camera system, an upgraded 48 MP 4x telephoto lens, a 48 MP ultra-wide sensor, and an 18 MP square-sensor front selfie camera with Centre Stage.

- High-Resolution Photography
- 4x Optical Zoom and 8x centre-crop optical quality zoom
- Simultaneous Video Recording
- Horizontal and Vertical Frame Capture Without Physically Turning the Phone
The major changes in iPhone 18 Pro include a variable aperture system and camera controls. It is expected to launch variable aperture on its 48MP Fusion Camera, which uses a physical six-blade system (f/1.78 and f/4.0), giving you better control over depth of field and light.
Also, the external camera control system is expected to be replaced by the swipe actions introduced in the iPhone 16/17 with press-based actions.
Improved features of iPhone 18 Pro include:
- Manual control over photography settings (adjusting aperture, setting specific shutter speed, etc)
- Advanced photography styles, cinematic, and video improvements
- Apple reference verification framework for authenticity
Key Takeaway:
The iPhone 18 Pro offers a massive upgrade ONLY for photographers and users who create cinematic photos and videos.
For general users, it may NOT be a massive upgrade.
