ESTIMATING AND PRESERVING BATTERY LIFE BASED ON USAGE PATTERNS

摘要

Embodiments apply user-specific usage patterns to estimate and preserve remaining battery life on a computing device. An amount of battery drain and an execution context are determined and stored for a plurality of recurring time periods. The execution context identifies operations executed by the computing device, signal strength, and other data describing the associated time period. If one of the operations is expected to be executed during a recurrence of at least one of the time periods, the expected execution is adjusted based on execution context and an estimated remaining battery life for the computing device. For example, the computing device may postpone or reschedule the operation for a time period during which the operation is expected to have a greater likelihood of completing successfully. In some embodiments, the battery preservation operations are automatically enabled at a particular threshold.

主权项

1. A system for updating battery records associated with a computing device, said system comprising:
a memory area associated with the computing device, said memory area storing a plurality of battery records each associated with one of a plurality of recurring time periods, each of the plurality of battery records including an amount of battery drain and a corresponding execution context for the computing device during the associated time period, said execution context identifying one or more operations executed by the computing device during the associated time period; and a processor programmed to:
detect a start of an execution activity and an end of the execution activity to identify one of the plurality of recurring time periods;determine data usage statistics relating to the identified time period;select one or more battery records from the plurality of battery records to store the determined data usage statistics, the one or more battery records being selected based on the identified time period; andupdate each of the selected one or more battery records with the determined data usage statistics, wherein the updated battery records represent a usage pattern for use when estimating and preserving battery life.
