Apple iPhone 17 vs Samsung Galaxy S26 Ultra

Our Verdict: Apple iPhone 17 and Samsung Galaxy S26 Ultra suit different priorities. The Samsung is stronger for display quality, helped by a larger 6.9-inch screen, a sharper 498 PPI display, and its Dynamic LTPO AMOLED 2X panel, while the iPhone is better suited to its LTPO Super Retina XDR OLED panel, a higher-resolution 18MP front camera, and a lighter 177g body. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Software may decide it too: the iPhone keeps you in Apple's iOS ecosystem, while the Samsung is the Android choice. Choose the Samsung for display quality; choose the iPhone if portability matters more.

Over a full contract, the iPhone 17 works out around £785 all-in, about £139 less than the S26 Ultra.
