Techniques are described for battery management in a computing device. The described techniques may be implemented by a battery offline module that provides functionality to control utilization of a battery such as determining whether the battery is available to receive power from a power source. For instance, the battery offline module may receive an input requesting that a battery be taken offline, determine whether system conditions for taking the battery offline are met, and take the battery offline when the system conditions are met such that the battery is not capable of receiving power from a power source of the computing device. In some instances, the battery offline module may cause different powering and charging arrangements between multiple batteries of the computing device. By implementing the battery offline module in the computing device, battery utilization is controlled to improve battery life.

Offline battery management in a device

A system for battery current monitoring includes a system power throttle stored in memory and executable by the one or more processors to place a battery of an electronic device into a state of expected zero-drain throughout a time interval while the electronic device remains active, and a battery leakage monitor stored in the memory and executable by the one or more processors to detect a battery charge leak based on a series of time-separated parameter measurements for the battery collected during the time interval.

Techniques for battery management of a device having multiple batteries are described herein. In one or more implementations, management for increased battery reliability involves assessing a combination of factors that influence a control policy for multiple batteries in a battery system. Based on the assessment, values of control parameters for power management of the battery system are set to reflect a tradeoff between performance and reliability. Then, at least one of battery utilization or charge current distribution is controlled in dependence upon the values that are set. Control of the battery system can be based in part upon differences in cycle counts for multiple batteries of a battery system for a device, such that cycle counts of the multiple batteries are managed for improved reliability.
