What is PowerInformer?
Have you ever noticed a sudden drop in the battery life of your laptop, and suspect it’s the result of the application you installed last week?
Have you ever wondered whether your application satisfies that 2-hour while-on-battery runtime requirement?
Have you ever tried to use Perfmon to gather power related statistics and given up after suffering serious information overload?
PowerInformer is a tool developed to provide basic power relevant statistics to a developer. They can use these statistics to optimize their application such that it matches battery life constraints (e.g. the game must run for at least 90 minutes on a notebook with a 56 W hr battery) while also meeting performance requirements.
