The iPhone 18 Pro just ended my affair with the iPhone Air
It was nice while it lasted. Kind of. Apple’s mechanical Variable Aperture and A20 Pro chip just redefined the flagship experience.
It’s not you, iPhone Air. It’s me. Actually, no. It’s you. I tried to love you. I defended you for over a year, stuck up for you in the face of ridicule from my Pro-wielding colleagues. But now that the iPhone 18 Pro is in my hand, I’m sorry to tell you, it’s over. Apple has officially launched the iPhone 18 Pro starting at ₹1,64,900 on Amazon in its striking new Burgundy finish, packing Apple’s first-ever mechanical Variable Aperture 48MP Fusion camera, the 2nm A20 Pro chip with vapour cooling, Ceramic Shield 2, and an unprecedented 35 hours of video playback. In this in-depth lab review, we benchmark both devices head-to-head.
1. Design & Burgundy Finish: Aluminium Unibody & Ceramic Shield 2
The iPhone 18 Pro introduces a refined aluminium unibody design with colour-matched back glass in four new finishes: deep Burgundy, Space Black, Silver, and Light Blue. The Burgundy variant is especially striking in person, shifting from deep wine in dim lighting to a metallic ruby in direct sunlight. Durability receives a massive upgrade with Ceramic Shield 2 on both the front and back, providing 3x better scratch resistance than the iPhone 16 Pro and industry-leading crack protection.
- •Finishes: All-new deep Burgundy, Space Black, Silver, and Light Blue
- •Protection: Ceramic Shield 2 front and back (3x better scratch resistance vs iPhone 16 Pro)
- •Ergonomics: 15.93 cm (6.3") form factor with chamfered edges and IP68 6-meter water resistance
2. Display: 6.3-inch Super Retina XDR with Anti-Reflective Coating
The 15.93 cm (6.3-inch) Super Retina XDR OLED panel retains Apple’s smooth ProMotion 120Hz adaptive refresh rate while introducing a revolutionary anti-reflective micro-coating. Outdoor peak brightness now reaches 2,600 nits, making HDR video editing and camera framing seamless even under direct Indian midday sunlight. The Always-On display has been optimized to consume 30% less power when displaying live iOS widgets.

The headline feature of the iPhone 18 Pro is the mechanical Variable Aperture on the 48MP Fusion main camera. Unlike previous fixed-aperture lenses, the physical blades dynamically adjust between wide F1.4 for natural optical bokeh and incredible low-light intake, and F2.8 for tack-sharp edge-to-edge landscape photos and group portraits where everyone is in focus. Photographers also get custom Pro controls and up to 8x optical-quality zoom.
4. Performance: A20 Pro Chip with Next-Gen Vapour Chamber & AI Engine
Built on TSMC’s bleeding-edge 2nm node, the A20 Pro features a Dual 16-Core Neural Engine purpose-built for on-device Apple Intelligence. For gamers and 3D creators, Apple added a dedicated copper vapour chamber that keeps thermals cool, unlocking up to 40% higher sustained GPU frame rates in console titles like Death Stranding and Resident Evil 4 with zero thermal throttling.
- ✓Architecture: A20 Pro 2nm chip with Dual 16-Core Neural Engine for Apple Intelligence
- ✓Graphics: Up to 40% faster sustained GPU performance than iPhone 17 Pro with hardware ray-tracing
- ✓Thermals: Next-generation integrated copper vapour chamber eliminates heat throttling
5. Battery & Charging: 35 Hours of Video Playback & 15-Minute 50% Charge
Battery life sees its biggest leap in iPhone history. The iPhone 18 Pro delivers up to 35 hours of video playback (an enormous 4-hour increase over the iPhone 17 Pro and 8 hours over the iPhone 16 Pro). In our real-world battery rundown test, it provided over 28 hours of mixed use per charge. Even more impressive is the fast charging: it hits 50% battery in just 15 minutes, and delivers 7 hours of video playback from an emergency 6-minute top-up.
- ✓Battery Stamina: Up to 35 hours video playback / 28 hours active screen time per charge
- ✓Wired Fast Charge: Up to 50% in approximately 15 minutes with high-wattage power adapter
- ✓Emergency Charge: 7 hours of continuous video playback on a quick 6-minute charge
6. Head-to-Head: iPhone 18 Pro vs iPhone 17 Pro vs iPhone 16 Pro
The iPhone 17 Pro remains a formidable flagship at ₹1,47,990 on Amazon with its A19 Pro chip and 31-hour battery life. However, the iPhone 18 Pro at ₹1,64,900 justifies its premium through the revolutionary Variable Aperture camera, 40% faster gaming GPU, Ceramic Shield 2 durability, and 15-minute rapid charging. For creators and power users, the 18 Pro is the definitive camera smartphone.
