This paper introduces a novel sensor-less, event-driven power analysis framework called FEPMA for providing highly accurate and nearly instantaneous estimates of power dissipation in an Android smartphone. The key idea is to collect and correctly record various events of interest within a smartphone as applications are running on the application processor within it. This is in turn done by instrumenting...
A modern smartphone or tablet-PC is typically equipped a high-resolution and large-size display, which is a primary power consumer. In spite of the relatively high power efficiency of organic light emitting diode (OLED) displays, the integrated display subsystem exhibits low energy efficiency due to power losses in the battery and the boost voltage conversion. In this paper, we for-mulize the system...
