There are the kernel level Android drivers which need system level permissions, correct permissions are easiest to deal with if these drivers were built with the Android kernel and already exist on the device. There are several components to the Intel Energy Profiler for an Android target. Screen captures were taken off a Windows host. It is assumed that the Mac* host will be similar, however the author does not have access to a Mac* host to directly verify the veracity of this claim. Some additional text provided for minor differences when running on a Linux host will be included. This guide walks through energy profiling on an Android target using tools included with Intel® System Studio as installed on a Windows host machine. Host and Target used for this Walk-Through: Host and Target used for this Walk-Through.Perform visual comparison of results to quickly quantify and demonstrate improvements.Explore CPU frequency to analyze power consumption issues.Monitor different hardware sleep states including sources of wake-ups.Power Analysis with Intel Energy Profiler: And perform visual comparison of results to quickly quantify and demonstrate improvements. Explore CPU frequency to analyze power consumption issues on your system. Monitor different hardware sleep states, including the reasons for hardware wakes-ups from a sleep state. Through analysis of power consumption one can identify the behaviors that waste energy and dramatically increase the battery life of your device. Intel® VTune™ Amplifier for Systems helps you optimize the power management of your code on Linux* embedded platforms, Android* or Windows* systems through the Intel® Energy Profile r analysis.
