Apple iPhone 17 Pro vs Samsung Galaxy S26 Ultra

Our Verdict: The Galaxy S26 Ultra pulls ahead on the big-ticket hardware differences: a 6.9-inch display instead of 6.3 inches, a sharper 498 PPI panel and a 200MP rear camera. The iPhone 17 Pro is still the more compact phone, just 206g compared with 214g, and it keeps the Apple A19 Pro, iOS and an 18MP front camera. Storage tops out at 1TB on both, so this comparison is really about Android's Ultra hardware and price advantage versus Apple's smaller Pro format and ecosystem. For most spec-led buyers the Samsung is stronger; for iOS users who want a smaller flagship, the iPhone remains the better fit.

The S26 Ultra is the cheaper one to own: around £956 over a typical contract, £163 less than the iPhone 17 Pro.
