Markets with comparatively lower smartphone taxes can therefore offer Apple's latest flagships at lower retail prices.A20 Pro chip and larger cooling system headline the upgradesThe iPhone 18 Pro and Pro Max introduce Apple's A20 Pro processor, which the company describes as its most capable iPhone chip so far. Apple says it can deliver up to 40% better sustained performance than previous generations.The chip combines a six-core CPU with a seven-core GPU. Each GPU core also includes dedicated neural accelerators aimed at improving AI processing.Apple has paired the processor with a next-generation vapour chamber cooling system. The company has introduced its largest such cooling system yet for the flagship lineup, with the aim of maintaining performance during demanding activities such as gaming and intensive multitasking.120Hz displays and a redesigned colour approachThe iPhone 18 Pro features a 6.3-inch Super Retina XDR display with ProMotion support up to 120Hz. The Pro Max gets a larger 6.9-inch version with the same display specifications.Both models use Ceramic Shield 2 for protection.Apple has also moved away from the earlier two-tone styling for the Pro series, opting instead for a single-tone colour scheme. The phones retain the full-width camera plateau on the rear.Variable aperture brings the biggest camera changeThe camera system receives one of the most notable additions this year. Both Pro models feature three rear cameras comprising a 48MP main camera, a 48MP ultrawide camera and a 48MP telephoto camera.For the first time, the main camera on both models uses variable aperture technology. This allows users greater control over how much light enters the lens, with potential benefits for photography and video shooting in different conditions.Both phones ship with iOS 27, which brings a refined Liquid Glass interface along with various Apple Intelligence features.iPhone 18 Pro and Pro Max price in IndiaIn India, the iPhone 18 Pro starts at Rs 1,64,900 for the 256GB model.
