How to measure and compare battery power consumption between Linux and Windows
I am finding that on my system.. ubuntu 13.10 is consuming much more power than Windows 8... (I get about 3.5 hours of battery on Windows and 1 hour on ubuntu)
From googling, this might be as a result of a combination of factors (biggest of which, is nVidia Optimus).. I would like to try out different methods and see how my power consumption and system temperature is affected. In order to do that I need to benchmark power consumption on windows and ubuntu and see how changes i make affect the performance.
I am new to phoronix. What test cases and methods would you suggest in order to benchmark and measure power consumption and CPU/GPU temp on both my ubuntu and windows partitions.
Thanks in advance,
Measure battery percentage instead
I now understand you can't measure power consumption directly in Windows, but I still am interested in measuring and comparing battery life in Ubuntu and Windows.
Could you suggest test suite or configuration that will show the difference in battery percentage (and if possible battery life in hours) before and after running it.
Thanks for your time,
