While true, that's like saying i++ is more efficient than i = i + 1 in an application that makes several SQL queries per run. You can micro optimize areas of code for better CPU (and thus battery) efficiency, but the largest use of power in a phone is the cellular radio, WiFi, bluetooth, screen, digitizer, and other bits of hardware. The CPU makes a difference, but most likely not in a noticeable way
