Abstract

Various embodiments of methods and systems for managing battery load in a portable computing device (“PCD”) are disclosed. One such method includes tracking an active load on a battery attributable to one or more active power consuming components. Measurements associated with the battery and indicative of the battery's state of health may also be monitored. When a call for additional load on the battery is recognized, such as a user request for provision of additional functionality in the PCD, a future load on the battery that considers the newly called load can be calculated. Based on an analysis of the impact on the battery's state of health, existing, lower priority loads may be scaled or suspended to create battery load capacity for the newly called load. In this way, quality of service and user experience may be optimized while minimizing conditions that could be detrimental to the battery.

First claim

What is claimed is:

1. A method for managing battery load in a portable computing device (“PCD”), the method comprising:
tracking an active load on a battery in the PCD, wherein the active load is associated with one or more active power consuming components within the PCD;
monitoring a state of health of the battery, wherein the state of health is quantified by one or more measurements associated with the battery;
storing data in a battery load database that identifies the on…
