Abstract: A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

Abstract: A method of enabling a battery hot swap in a mobile device includes detecting when a removable first battery will be removed. The removable first battery may power the mobile device. The method includes reducing a system current to a predetermined level in response to the detecting. The method may further include sourcing current from a second battery when the removable first battery is removed.

Abstract: Techniques and apparatus for providing battery protection. One example technique for providing battery protection generally includes monitoring a voltage of a battery node during an off mode of a device having a battery coupled to the battery node, determining that the voltage of the battery node is below a first threshold voltage, and disconnecting a path between the battery node and a power supply node of the device in response to the determination.

Abstract: Faster charging of a battery, including: opening a first switch disposed between an input node of the battery and an input node of a load to decouple the input node of the battery from the input node of the load; and charging the battery using a first charging source coupled to the input node of the battery while the load is being powered through the input node of the load via a second charging source having a charge rate slower than the first charging source.
