Operational mode-based battery monitoring for a battery-powered electronic device
First Claim
1. A method of monitoring a remaining charge level of a battery in an electronic device after an operational mode is performed by the device, the operational mode comprising one or more operations of the device, the device obtaining at least some power from the battery, the method comprising:
- waiting a mode-specific period of time after the performed operational mode before determining the remaining charge level of the battery, the mode-specific period of time being based on a recovery time for the battery, the recovery time being specific to the operational mode.

Abstract
A method and an electronic device monitor a battery of the device with respect to device operational mode in one or both of battery charge level monitoring and battery cut-off determination. Mode-based monitoring employs a mode-specific wait period prior to performing a measurement used to determine a remaining charge level of a battery. The mode-specific wait period depends on the operational mode immediately preceding the measurement and therefore, accounts for battery recovery effects on measurement accuracy. Mode-based cut-off determination employs information regarding an impending operational mode to determine whether or not a remaining charge level of the battery is sufficient to support the mode. Only those operational modes for which there is sufficient remaining charge are enabled while operational modes for which there is insufficient remaining power are disabled.

10. A method of determining a cut-off point of a battery used in an electronic device, the electronic device obtaining at least some power from the battery, the cut-off point being a point in a discharge profile of the battery at which there is insufficient power to perform an operational mode of the device, the method comprising:
determining whether a remaining charge level of the battery is insufficient to perform an operational mode, the remaining charge level being insufficient when the operational mode utilizes more power than that associated with the remaining charge level. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
