Why choose each?
Different strengths. Your call.
REASONS TO CONSIDER
OnePlus 15
Longer native telephoto reach
3.5× vs 3× 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
6.78″ vs 6.2″ diagonally. Larger is a preference, not an automatic win.
Preference, not included in the match score.
REASONS TO CONSIDER
Galaxy S25
53 g lighter
162 g vs 215 g, before a case. Also 6.2 mm narrower.
Preference, not included in the match score.
Published facts, not hands-on recommendations. These preferences do not add extra points to the match score; no tested battery gains are inferred.

Relative published specs · outer edge = higher value
Display explainedNot enough evidence to score
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.
Galaxy S25: Uses Samsung's 2,600-nit peak claim, pixel density calculated from 2340×1080 over 6.2 inches and maximum adaptive 120Hz. This models published capabilities, not independently tested display quality.

Your weighted scoreNot availableSelected categories: None.
Comparable evidence is missing in one or more selected categories.
DisplayNot scored
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.
Selected weight: 1.
Missing: Unambiguous peak-brightness measurement definition.
CameraNot scored
Verified camera hardware is shown separately. The complete v1 pro-workflow audit is not available, so no camera-quality or capability score is inferred.
Selected weight: 1.
Missing: Complete model-specific verification of the four pro-workflow inputs.
BatteryNot scored
The 31-hour video claim does not establish the local-playback protocol required by v1. The published video duration and charging claims remain visible without an inferred battery score.
Selected weight: 1.
Missing: Verification that the 31-hour claim uses local-video playback.
PerformanceNot scored
No comparable independent cross-platform CPU, GPU and sustained-performance tests are included.
