Abstract
A system and method for predicting remaining battery life for a portable information handling systems include determining power consumption for an OLED display based on an on pixel ratio (OPR) for each pixel. When a user starts a session of an application and a file, file metadata may be used to search a database storing OPR profiles, with each OPR profile including one or more time series associated with one or more instances of the application executing the file. For static files, a time series in an OPR profile may be used to predict power consumption and calculate battery life. For dynamic files, periodically measuring OPR data may be used to predict power consumption. For some dynamic files, historic OPR values and periodic measurements may be used to predict power consumption. The user may be provided with a list of files usable during the calculated battery life.
