HW-149P Improving battery life and energy efficiency Charu Agrawal Program Manager Microsoft Corporation
Agenda • Overview of Energy Efficiency Assessment • Demo of Energy Efficiency Assessment • Energy Efficiency Results You’ll leave with examples of how to • Measure battery life using Energy Efficiency Assessment • Identify Energy Efficiency issues to improve battery life
“Measure, analyze and improve Energy Efficiency/Battery Life of your system”
Battery Life Measurement is difficult • Lack of diagnostic capabilities • Destructive nature of tool sets • Lack of flexibility
Highlights of Energy Efficiency Assessment • Non destructive test • Flexible and customizable • Wide range of data [Ranging from duration to CPU/Disk metrics ] • Idle energy efficiency issues
Value Proposition • OEM/Developer/End user • Consistent and yet flexible way to understand, improve, and compare Energy Efficiency • App Developer • Measure the impact of various applications on the Energy Efficiency
Impact • End users making well informed decisions • OEMs configuring system for better battery life • Developers improving applications and drivers for better power consumption
Assessment Configuration Idle Streaming Media File Handling • Select workloads • Select the execution mode • Define start and end condition Photo Handling
Assessment Execution • Verifies the pre requisite conditions • Prepares for Energy Efficiency test • Execute the workloads, until the specified • battery end condition is met
Results • Key metrics on battery consumption and diagnostics • Issues causing poor energy efficiency during idle • WPA analysis capability • Ability to compare different results; Across same or different machines
Dos & Don’t Close all the open applications Do not start any other applications or jobs Do not interact with the machine once the assessment starts
