iPhone 15 vs Galaxy S23
The short version
Both are compact, premium 6.1-inch flagships with different strengths. Choose iPhone 15 if you prefer iOS, top-tier video quality, longer typical OS longevity, satellite safety features, and Apple ecosystem accessories. Pick Galaxy S23 for the 120 Hz display, built-in 3x telephoto, faster wired data via USB 3, DeX desktop mode, and broader customization on Android. Photographers who zoom benefit from S23; videographers and those invested in Apple services may prefer iPhone 15.
