Why choose each?

Different strengths. Your call.

REASONS TO CONSIDER

iPhone 17 Pro Max

  • Longer native telephoto reach

    4× vs 3.5× native telephoto. Lens reach, not digital zoom or an image-quality verdict.

    Verified hardware; Camera is not scored for this pair.
  • More screen, if you want it

    6.9″ vs 6.78″ diagonally. Larger is a preference, not an automatic win.

    Preference, not included in the match score.
Sources behind these differences 2

Published facts, not hands-on recommendations. These preferences do not add extra points to the match score; no tested battery gains are inferred.

Relative specification comparisonComparing iPhone 17 Pro Max and OnePlus 15. The outer edge is the higher published value in this pair. Unknown metrics are omitted. Manufacturer test methods vary; larger does not always mean better.Pixel densityNative zoomVideo timeRefresh rateRelative published specs · outer edge = higher value
Display explainedNot enough evidence to score

iPhone 17 Pro Max: Scores Apple-published 3,000-nit outdoor peak brightness, 460 ppi and adaptive refresh up to 120Hz. Peak brightness is not independently measured.

OnePlus 15: The UK specification publishes 1,800 nits in high-brightness mode, while launch wording calls it peak brightness. These measurement labels are not interchangeable, so v1 peak-brightness scoring is withheld. Verified pixel density and refresh limits remain visible.
