1. A method comprising:
detecting, by a motion sensor of an information handling system, a predefined motion pattern;
providing a trigger signal as a battery charge request in response to the predefined motion pattern being detected;
requesting, by an embedded controller of the information handling system, a relative state of charge of a battery in response to the trigger signal;
receiving, by a battery management unit of the information handling system, the request for the relative state of charge of the battery from the embedded controller;
reading the relative state of charge of the battery;
providing, by the battery management unit, the relative state of charge of the battery to the embedded controller;
receiving, by the embedded controller, the relative state of charge of the battery;
providing an indication signal for the relative state of charge of the battery; and
outputting, by a battery charge indicator, an indication of the relative state of charge of the battery based on the indication signal.
