The present invention provides a mobile communication device comprising a battery and a plurality of hardware and software components and a charge conserving system capable of defining one or a number of charge thresholds, wherein the or each charge threshold corresponds to a quantity of remaining electrical charge in the battery and the charge conserving system is further capable of determining a remaining electrical charge in the battery, and automatically broadcasting a charge status notification to at least one of a predefined group of the hardware and software components when the remaining electrical charge in the battery falls below the or each charge threshold. The notification may be provided to a different set of the predefined group of components when a different threshold is passed and each hardware or software component may be capable of reducing its charge demand on the battery on receipt of the notification and/or the charge conserving system may comprise a decision engine that may instruct shutdown when charge falls below a threshold. A charge status notification may also be provided when charge rises above a threshold and the components may increase their charge demand and/or be instructed to start-up. The charge thresholds may be defined at least in part by user input and at least part of the predefined group may be defined at least in part by user input and/or by which components have registered with the charge conserving system. Preferably the components that are shut down are those not required for a telephony function. |
