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

OnePlus 15T7,500 mAh
Samsung Galaxy S23 Ultra5,000 mAh

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