I think in some cases "improved" efficiency for mobile has actually harmed subjective performance, because it encourages trading latency for throughput. I care more about how fast software feels than how fast it benchmarks. Worst cast latency matters. I'd happily accept a thicker and heavier device if it meant I never had to wait for it.
