SMART POWER SCHEDULING FOR USER-DIRECTED BATTERY DURATION

摘要

The systems and method described herein provide smart power scheduling for an electronic device. A user can specify a desired battery duration for the electronic device. Smart power scheduling can modify operation of the electronic device, when appropriate, so that the desired battery duration is met. The user may, for example, know that she will be unable to charge her smartphone for 10 hours and specify a desired battery duration of 10 hours. If during the 10 hours, the user plays a game on the smartphone that drains the battery too fast to meet the 10-hour desired battery duration, the smartphone can modify its operations, for example, by lowering the graphics resolution, to achieve the user-specified desired battery duration. When smart power scheduling modifies operations, it may limit the impact on the user experience, for example, background tasks may be modified before foreground tasks are modified.

主权项

1. A method for power scheduling in an electronic device including a plurality of cores operable in a plurality of power states, the method comprising:
receiving a user-defined battery duration; receiving activity information from the plurality of cores; determining, based on the activity information, whether the user-defined battery duration is supported; and in the case that the user-defined battery duration is not supported, determining a new power state for at least one of the plurality of cores.
