iPhone 18 Pro vs iPhone 17 Pro: Is it worth the upgrade?
Apple’s iPhone 18 Pro arrives with a faster A20 Pro chip, variable‑aperture camera and longer battery life, but the changes are incremental over the 17 Pro. The new model is £100 more expensive and offers only modest improvements, making the 17 Pro a strong value option for most users.
Apple’s latest flagship, the iPhone 18 Pro, launched on 12 September with a pre‑order price of £1 199 for the 256 GB base model. The device arrives a full year after the iPhone 17 Pro, which was priced at £1 099 at launch. The new model carries a £100 price increase, but Apple has promised a handful of upgrades that could justify the extra cost for power users and photography enthusiasts.
What’s New on the iPhone 18 Pro?
The most headline‑making change is the introduction of a variable‑aperture main camera. Unlike the fixed f/1.8 aperture on the 17 Pro, the 18 Pro’s 48‑MP sensor can physically adjust its opening to four settings – f/1.48, f/1.8, f/2.8 and f/4.0 – allowing users to trade light intake for depth of field or vice versa. Apple also claims the wider f/1.48 setting delivers 50 % better low‑light performance. The camera system remains a triple‑lens setup (48 MP main, 48 MP ultra‑wide, 48 MP telephoto), but the new sensor and computational pipeline give photographers more manual controls, including shutter speed, white balance and a live histogram.
Under the hood, the iPhone 18 Pro runs Apple’s A20 Pro chip, a step ahead of the A19 Pro that powers the 17 Pro. The upgrade is expected to improve gaming, augmented‑reality experiences and overall system responsiveness. Battery life also sees a boost, with the 18 Pro offering up to 34 hours of video playback compared to 31 hours on the 17 Pro.
Design changes are subtle. Both phones share a 6.3‑inch Super Retina XDR OLED display with a 2622 × 1206 pixel resolution, 120 Hz adaptive refresh rate and 1 600‑nit peak HDR brightness. The aluminium unibody, Ceramic Shield 2 and camera plateau remain unchanged, but the 18 Pro’s Dynamic Island is slightly smaller and can now show three live activities simultaneously instead of two. The colour palette has been refreshed: the 18 Pro comes in burgundy, glacier blue, black and silver, while the 17 Pro’s cosmic orange has been dropped.
How Does It Compare to the iPhone 17 Pro?
In terms of size and weight, the two models are identical – 150 mm × 71.9 mm × 8.75 mm – but the 18 Pro is 7 g heavier (211 g vs 204 g). The display, camera resolution and battery capacity are also the same, making the 18 Pro an incremental upgrade rather than a redesign.
Performance gains from the A20 Pro are noticeable in high‑end gaming and multitasking, but everyday tasks such as browsing, messaging and social media use are unlikely to feel significantly faster. The variable‑aperture camera is the most tangible benefit for photography enthusiasts, offering better low‑light shots and more creative control.
What About Pricing and Deals?
Apple’s pricing strategy has left the 17 Pro as a compelling alternative. The 17 Pro now retails at £1 099, but many retailers offer discounts that bring the price down to the low‑hundreds. Trade‑in programmes from Apple, Amazon, Currys and John Lewis can reduce the cost by up to £615, depending on the device you hand in. Retailers also offer 0 % finance, allowing the cost to be spread over 24 months.
Carrier deals add another layer of savings. Sky Mobile, EE, O2 and Vodafone all provide discounted data plans and contract options for the 17 Pro and 17 Pro Max. For example, Sky Mobile offers the 17 Pro for £31.50 per month over 36 months with a £12 upfront fee, while Giffgaff and Smarty provide low‑cost SIM‑only plans that pair well with a new iPhone.
Is the Upgrade Worth It?
For most users, the incremental improvements of the iPhone 18 Pro – a faster chip, variable‑aperture camera and slightly longer battery life – do not justify the £100 price hike. Photographers who need the new camera controls may find the upgrade worthwhile, but casual users and those on a budget can still get a powerful device with the 17 Pro, especially when combined with trade‑in or carrier discounts.
Apple has not announced a standard iPhone 18 yet, so the 17 Pro remains the most affordable flagship option. The 18 Pro’s launch also coincides with Apple’s first foldable, the iPhone Duo, which may shift attention away from the Pro line for a while.
In summary, the iPhone 18 Pro offers a few high‑end upgrades, but the 17 Pro remains a strong value proposition for the majority of buyers. If you’re looking for the best price‑to‑performance ratio, the 17 Pro – especially with a trade‑in or carrier deal – is the smarter choice.
