Low power warning in a portable communication device based on predicted device utilization
View Patent ↗A system and method for providing a low power warning in a portable communication device based on predicted device utilization. Various aspects of the present invention may comprise monitoring power utilization for a portable communication device. A power utilization profile may be determined based, at least in part, on the results of the power utilization monitoring. Power availability for the portable communication device may be determined. Future power need for the portable communication device may be predicted based, at least in part, on the determined power utilization profile. The predicted future power need and the determined power availability may be analyzed to determine whether to generate a warning indicating a potential future power shortage. If it is determined that a potential future power shortage warning should be generated, such a warning may be generated. Such a warning may, for example, be generated in accordance with user specifications.
