Apple iPhone 15 vs Apple iPhone 17 Pro Max

Our Verdict: Comparing Apple iPhone 15 and Apple iPhone 17 Pro Max, the choice mostly comes down to display quality versus portability. The Pro Max gives you a larger 6.9-inch screen, its LTPO Super Retina XDR OLED panel, and a higher-resolution 18MP front camera, while the 15 is more appealing for its Super Retina XDR OLED panel and a lighter 171g body. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Choose the Pro Max for display quality; choose the 15 if portability matters more.

The 15 5G is the cheaper one to own: around £525 over a typical contract, £640 less than the 17 Pro Max.
