If you're weighing up a refurbished iPhone 17 vs iPhone 16 UK purchase in 2026, you're in exactly the right place. The iPhone 17 landed in September 2025 with some genuinely exciting upgrades — a bigger 120Hz ProMotion display, a dramatically better ultra-wide camera, and a new A19 chip — while the iPhone 16 has been available refurbished for over a year and offers strong value at a lower price. So which should you actually buy? This guide breaks down every key difference.

Display — iPhone 17 Finally Gets ProMotion

One of the most compelling upgrades on the refurbished iPhone 17 is its display. For the first time on a non-Pro iPhone, Apple has included ProMotion 120Hz adaptive refresh rate technology — previously exclusive to the Pro lineup. The result is visibly smoother scrolling, animations, and gameplay, making the iPhone 16's 60Hz panel feel noticeably dated by comparison.

The iPhone 17 also upgrades to a larger 6.3-inch Super Retina XDR OLED screen (up from 6.1 inches on the iPhone 16), with a peak brightness of 3,000 nits and the new Ceramic Shield 2 offering three times better scratch resistance. For a refurbished device that may already have seen some use, that extra scratch resistance is a real-world benefit. The iPhone 16 is still a beautiful display — OLED, vibrant, sharp — but in 2026, the 60Hz limitation is increasingly hard to overlook.

Performance — A19 vs A18

The iPhone 17 runs on Apple's A19 chip (3nm architecture), a step up from the A18 in the iPhone 16. Day-to-day, both chips feel fast and capable: apps open instantly, multitasking is smooth, and Apple Intelligence features — including on-device writing tools, Photo Clean Up, and enhanced Siri — run fluidly on both devices.

The difference becomes more meaningful when you think long-term. If you're planning to keep your refurbished iPhone for four or five years, the A19 gives you more performance headroom and may extend software support longevity. Both models are expected to receive Apple software updates into the early 2030s, but starting on the newer silicon is always a plus.

Camera System — The Ultra-Wide Revolution

Main Camera

Both the iPhone 16 and iPhone 17 share a 48MP Fusion main camera, so standard daylight and portrait shots are comparably excellent. The A19 chip improves computational photography slightly, but the output is broadly similar.

Ultra-Wide Camera

This is where the iPhone 17 genuinely pulls ahead. Apple upgraded the ultra-wide lens from 12MP to 48MP — a fourfold increase in resolution. In practice, landscape shots, architecture, group photos, and macro images are all substantially sharper and more detailed. This is the same upgrade the Pro models received a generation earlier, and it's a meaningful differentiator for anyone who regularly uses the wide-angle lens.

Front Camera

The selfie camera also improves: 18MP on the iPhone 17 vs 12MP on the iPhone 16. Portraits, video calls, and FaceTime sessions all benefit from the higher resolution and improved Centre Stage framing on the iPhone 17.

Battery Life

The iPhone 17 carries a slightly larger 3,692 mAh battery compared to the iPhone 16's 3,561 mAh. Combined with the more efficient A19 chip, the iPhone 17 edges ahead in real-world usage — reviewers found it lasting approximately 20–30 minutes longer under typical daily workloads. Both phones support USB-C fast charging (50% in 20 minutes) and MagSafe wireless charging.

When buying a refurbished iPhone 16 or 17, always check the battery health percentage. At refurb-phone.com, every refurbished iPhone is tested and any battery below 85% capacity is replaced before sale, so you can be confident in what you're getting.

Storage Options

The iPhone 17 doubles the base storage to 256GB for the same starting price as the iPhone 16's 128GB base model. In 2026, with iOS, apps, photos, and videos consuming ever more space, 128GB can feel limiting. If you do opt for a refurbished iPhone 16, we'd strongly recommend choosing a 256GB model — available alongside refurbished iPhone 17 models at refurb-phone.com.

Refurbished UK Prices in 2026

Model Storage Refurbished UK Price (from)
iPhone 16 128 GB ~£450
iPhone 16 256 GB ~£499
iPhone 16 512 GB ~£569
iPhone 17 256 GB ~£598
iPhone 17 512 GB ~£699
iPhone 17 1 TB ~£799

The price gap between the two models narrows significantly in the refurbished market. The step from a 256GB iPhone 16 (~£499) to a 256GB iPhone 17 (~£598) is just £100 — and you get ProMotion 120Hz, a 48MP ultra-wide, a better front camera, and a newer chip for that premium. As refurbished iPhone 17 supply grows through 2026, prices are expected to fall further.
