iPhone 16 wins on performance and longevity with A18 chip benchmarks 18% higher single-core than Snapdragon 8 Elite per Geekbench 6 and 6 years of updates versus 5. Galaxy S25 offers 120Hz display and faster 45W charging but trails in sustained battery life at 3561mAh equivalent capacity. Both score similarly on design but iPhone 16 edges value through stronger resale data.
