Hitting the UK market on the 19th September 2025, Apple's iPhone 17 landed, offering users a bigger screen, a faster chip and a sharper camera setup. But is it worth skipping or upgrading the iPhone 16 for?
Before you make up your mind, let's compare the two side by side and find out why buying refurbished might be the smarter decision for you.
Design and Display
The iPhone 17 and iPhone 16 share a similar shape, but the iPhone 17 steps things up with a 6.3 inch up from 6.1 inches, and it's the first standard iPhone to get ProMotion, giving it a smooth 120Hz refresh rate, whereas the iPhone 16 is locked to 60Hz. Apple has also fitted the iPhone 17 with Ceramic Shield 2, offering three times better scratch resistance than the iPhone 16’s front glass.
Performance and Camera
Under the hood, the iPhone 17 runs on Apple's new A19 chip; this is a genuine step up from the iPhone 16/s A18. This is beneficial for gaming and non-device AI tasks.
Camera-wise, both phones use a 48MP main sensor,r but the iPhone 17 adds a fully upgraded 48MP Ultra Wide lens and an improved 18MP Center Stage front camera compared to 12MP on the iPhone 16. This is a noticeable jump for anyone who shoots a lot of video calls or selfies. You can catch the full specifications available on Apple’s official website. Whichever setup you choose, every device sold through Tech Tiger is professionally tested and data wiped before it's graded and listed.
Battery, AI Features and Software Support
Is the iPhone 17s battery better than the 16? Nominally, but independent testing shows both phones deliver similar all-day battery life, so it isn't a clear win either way. Where the iPhone 17 does pull ahead is charging speed, supporting faster 40W wired charging against the iPhone 16's slower speeds. Both support Apple intelligence, including Writing Tools and visual intelligence, though reviewers note the toolkit remains a modest feature on both rather than a reason to choose one over the other. Apple typically covers each iPhone with major iOS updates for around six years, so both models should stay current for some time yet.
Should You Upgrade?
If you already own an iPhone 15 or earlier, the iPhone 17 is a worthwhile step up, especially for the display and camera. If you're on an iPhone 16, the differences while real are incremental, so there's no urgent need to upgrade unless ProMotion or the new front camera is something that actually matters to you.
Why Buy Refurbished
This is where buying refurbished makes sense. A refurbished iPhone 17 or refurbished iPhone 16 gives you the same performance at a significantly lower price than buying new. At Tech Tiger, every device is fully tested, graded and covered by a 13-month warranty with free next-day delivery and Klarna available if you'd rather spread the cost. And it's backed by an 'Excellent' Trustpilot rating and a tree planted with every order.
Whether you want a refurbished iPhone 17 Pro Max for the best cameras and battery life, a more affordable refurbished iPhone 16 or a refurbished iPhone 16 Pro or iPhone 17 Pro in between, choosing refurbished means better value without compromising on quality and a more sustainable choice too.
