Monitoring and managing processor activity in power save mode of portable electronic device

摘要

An electronic device and a method operative therein monitor automatic wakeup events that occur during a power save mode. Wakeup events are monitored for respective applications executable within the electronic device. Applications with processing activity during the power save mode are then listed, on the basis of at least the monitored wakeup events. An indication of which apps are consuming battery power during the power save mode can then be obtained.
