There’s a lot to like about the iPhone 7, but is it worth upgrading to? It is if you care about performance and battery life. The iPhone 7 boasts the A10 Fusion, a four-core 64-bit processor with two high-efficiency cores and two high-performance cores. With the processor comes 40-percent faster processing over the A9 and two times processing over the A8. It’s a big jump in processing performance over the iPhone 6s, and is especially faster than older models — in fact, Apple says it is 120x faster than the original iPhone.
