Performance

Higher benchmark score = faster

Apple iPhone 18 Pro3,402,829
Apple iPhone 15 Plus1,385,649

Benchmark score — a measured indicator of raw performance, not a guarantee of real-world speed.

Battery capacity

Larger cell — a hardware spec, not battery life

Apple iPhone 18 Pro4,056 mAh
Apple iPhone 15 Plus4,383 mAh

Capacity is the raw battery size. Real-world battery life depends just as much on the processor, software and display.
