2025 vs 2015 iPhone: 10 Years of Unbelievable Growth
If you compare Apple’s 2015 iPhone 6s to the 2025 iPhone 17, the performance jump is staggering. In just one decade, Apple has reportedly increased the iPhone’s multi-core performance by over 1,000% and GPU performance by a jaw-dropping 1,600%, according to recent benchmark data.
A19 Pro Chip Powering the iPhone 17
At the heart of this revolution is Apple’s latest A19 Pro chip, built on a 2nm process. This chip delivers breakthrough efficiency and power, with multi-core Geekbench scores exceeding 14,000 — a level once reserved for professional desktops.
In comparison, the iPhone 6s’s A9 chip scored just over 2,400 in the same test. That’s a tenfold jump in processing power, making the iPhone 17 a true supercomputer in your pocket.
Graphics Power: 1,600% Faster GPU Performance
The graphical performance leap is even more dramatic. Apple’s shift to its Pro-class GPU architecture has resulted in a 16x increase in graphics power compared to 2015 models.
This means console-level gaming, professional 3D editing, and even AI-based rendering are now possible on iPhone — something unimaginable ten years ago.
Battery and Efficiency Leap
Despite the massive boost in power, Apple’s efficiency gains are just as impressive. The iPhone 17 offers up to 40% longer battery life than older models, thanks to the A19’s adaptive performance cores and Apple’s advanced cooling and optimization.
From 2GB to 12GB RAM: A Memory Revolution
In 2015, the iPhone 6s had just 2GB of RAM. Fast forward to 2025, and the iPhone 17 comes with up to 12GB LPDDR5X memory, supporting multitasking, ProRAW editing, and real-time AI computing.
A decade ago, the iPhone 6s introduced 3D Touch and Live Photos — groundbreaking at the time. Today, the iPhone 17 brings AI-driven photography, spatial video, and ray tracing graphics.
From hardware to software, Apple’s decade-long innovation shows just how far the iPhone has come — and how much further it can go.
