Apple iPhone 17 vs Samsung Galaxy S26 Ultra

Our Verdict: The Galaxy S26 Ultra brings the more ambitious hardware, with a 6.9-inch 498 PPI display, a 200MP rear camera and storage up to 1TB. The iPhone 17 is smaller, lighter and cheaper, and its 48MP rear camera and Apple A19 Pro chipset still put it firmly in flagship territory. Battery capacity also favours the S26 Ultra at 5000mAh versus 3692mAh, although that is not a direct battery-life comparison across Android and iOS. Pick the Samsung if you want the bigger screen and Ultra feature set; pick the iPhone if value, portability and Apple iOS matter more.

Over a full contract, the iPhone 17 works out around £801 all-in, about £155 less than the S26 Ultra.
