iPhone 18 vs iPhone 17: The upcoming iPhone 18 series by Apple has become the talk of the town long before its release in 2026. The speculations are rife over major overhauls that would redefine the smartphone lineup altogether-from a more intelligent design to a possible foldable model. So, here’s everything about five of the biggest upgrades that Apple is reportedly bringing over the iPhone 17 series.
New Camera Button Design
It appears that Apple is reworking the Camera Control button on the iPhone 18 to streamline the mechanism from the sapphire-covered, pressure-sensitive system on the iPhone 17, without losing gesture-based shooting controls. This could make the button more durable and cost-effective without losing Apple’s signature camera intuitiveness.
Powerful A20 Chip Built on 2nm Process
The iPhone 18 will feature, under its hood, an all-new Apple A20 chip fabricated on a 2nm process. Compared to the A19 3nm chip of the iPhone 17, it should offer stronger performance with higher energy efficiency and better AI handling, promising quicker processing, smoother multitasking, and wiser real-time image and voice recognition.
Bigger RAM for Base Model
The base model of the iPhone 18 might finally see an increase to 12GB RAM, matching that of the Pro variants of the iPhone 17. LPDDR5X memory from Samsung can really help improve the overall AI-based operations and speed of multitasking. Users can expect more responsive app handling, with better background performance even for resource-intensive tasks.
Refined Dynamic Island
The iPhone 18 series could feature an updated version of the familiar Dynamic Island design, reportedly smaller and more compact in a pill-shaped cutout. Such a design would give more screen area and offer a nearer full-screen look. This change in design will help with aesthetic goals without sacrificing the feature’s intended functionalities of showing notifications and live activities.
New Model Strategy and Foldable iPhone
Apple may launch three flagship models: the 18 Pro, 18 Air, and revolutionary iPhone 18 Fold for 2026. The foldable variant represents Apple’s entrance into a new form factor, joining premium hardware with cutting-edge hinge technology. Meanwhile, the respective releases of the regular iPhone 18 and the iPhone 18e may follow in early 2027 as part of a new staggered release cycle that reflects Apple’s evolving strategy for the future.
