Yes they have. It's why we have 10+ hour thin & light laptops. The quad-core i5 in a macbook air runs at 10W, that's comparable per-core power draw to an A13.
Controlling the CPU will give Apple more controls to tune total-package power, particularly on the GPU / display side of things, but CPU compute efficiency isn't going to be radically different, and that's not going to translate into significant battery life differences, either, since the display, radios, etc... all vastly drown out low-utilization CPU power draw numbers.
