Method and device with enhanced battery capacity savings

摘要

An enhanced battery saving capacity device (200) and method (300) is disclosed. In its simplest form, the method (300) includes the steps of: detecting (310) an off state by detecting a load current below a threshold; and entering (320) a battery saver mode including a duty cycle test period, by: providing a periodic test signal; disconnecting a battery for a first interval of time; and reconnecting the battery for a second interval in synchronization with the periodic test signal, to determine whether the load current exceeds the threshold. The method (300) can reduce power drain when an electronic device is off or stored for an extended period of time. It can also extend the shelf life and minimize the possibility of damage to the life cycle of a battery, by lowering the possibility of severe discharge of a battery.

1. An enhanced battery saving method of an electronic device including a battery, the method comprising:
detecting an off state of a host associated with the electronic device by detecting a load current below a threshold while the electronic device is not connected to an external power source; and entering a battery saver mode including a duty cycle test period having a plurality of first time intervals and a plurality of second time intervals, by:
providing a periodic test signal;disconnecting the battery from the host for a first interval of time of the plurality of first time intervals; andreconnecting the battery to the host for a second interval of time of the plurality of second time intervals in synchronization with the periodic test signal to determine whether the load current exceeds the threshold.
