This CL adds logging to areas which are possible suspects for the slowdown some people have been reporting in the PowerUsageAdvanced screen. It times the time it takes for various battery stats methods as well as the time it takes to draw things. Test: still build (only adds logging) Bug: 62959645 Bug: 63442960 Change-Id: I7e6c5e83e33a931057c9fdef14d3bef84f514940
