Intel® Energy Profiler 2016 Beta for Systems - Windows* Host
In this article I give a brief overview of power and performance optimization methodology on mobile devices. I hope it will help you better understand the challenges involved. I also provide instructions for how to measure device power consumption from the battery controller on Android.
Why is power and performance optimization so challenging on mobile devices? Let’s quickly review how power and performance optimization is performed in HPC (High Performance Computing).
The important metrics regarding power consumption in HPC are:
Sometimes when technology changes, you can't really see yourself using the new features, especially in a business setting. However, I don't think anyone will have that problem with the move to wire free PCs. (Or why to care about Wi terms: WiDi, WiGig/WiDock, Wireless Charging, )

How about the future? Have we reached the pinnacle of power management?
Unlike a lot of previous recent blogs, this series is about power management in general. At the very end of the series, I’ll write specifically about the Intel® Xeon Phi™ coprocessor.
I have talked incessantly over the years about power states (e.g. P-states and C-states), and how the processor transitions from one state to another. For a list of previous blogs in this series, and well as other related blogs on power and power management, see the article at [List0]. But I have left out an important component of power management, namely the policy.
