Apple iPhone 17 vs Samsung Galaxy S23

Our Verdict: This is a straightforward iOS-versus-Android choice, but the hardware differences are big enough to matter. iPhone 17 is sharper at about 458 PPI versus 422, while the main-camera figures are close at 50MP and 48MP; iPhone 17 stretches further on storage, topping out at 512GB rather than 256GB. S23 is clearly cheaper over a contract, which puts pressure on iPhone 17 to justify the extra spend. Pick iPhone 17 only if its upgrades are important to you; otherwise S23 is the better-value buy.

The S23 5G is the cheaper one to own: around £544 over a typical contract, £237 less than the iPhone 17.
