Predictive reader power management
First Claim
1. An electronic reader, comprising:
- at least one processor;
a display driver coupled to the at least one processor to render content on a display of the electronic reader; and
memory coupled to the at least one processor and containing power control instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising;
predicting when a user'"'"'s next interaction with the electronic reader will occur based on the user'"'"'s past interaction with the electronic reader, the user'"'"'s interactions comprising electronic page turns of an electronic book stored in the memory of the electronic reader; and
controlling an amount of power consumed by the electronic reader based on the predicting, the controlling comprising;
initiating a first power state to control an amount of power consumed by the processor, the display driver, and the memory when content has previously been rendered and is currently being displayed by the electronic reader;
initiating a second power state different from the first power state to control an amount of power consumed by the processor, the display driver, and the memory when loading a next electronic page of content in the memory, andinitiating a third power state different from the first and second power states to control an amount of power consumed by the processor, the display driver, and the memory when rendering the next electronic page of content on the display of the electronic reader.

Abstract
Power management features of a reader device control an amount of electrical energy supplied to the reader device. The power management features include several power control categories that a user may select to affect an amount of power consumed by the reader device. One power control category controls power consumption based on a genre of an electronic book being processed by the reader device. Another power control category controls power consumption based on a time of day an electronic book is being processed by the reader device. Power control instructions that control how much power a reader device consumes may also be generated based on a characteristic of a user'"'"'s interaction with the device.
