1. A method of managing charging of a battery of an information handling system, the method comprising:
determining that the battery is in a standard charging mode;
in response to determining that the battery is in the standard charging mode:
for a first time interval, charging the battery with a first power provided by a power supply unit (PSU), the first power associated with the standard charging mode;
determining that the first time interval has elapsed;
in response to determining that the first time interval has elapsed, for a second time interval after the first time interval:
determining whether the battery is in a constant voltage mode or a constant current mode;
in response to determining that the battery is in the constant voltage mode:
determining a current voltage of the battery;
determining an offset voltage based on the current voltage of the battery and a current output voltage of the PSU; and
charging the battery with a second power provided by the PSU, the second power based on the offset voltage, the second power greater than the first power,
wherein the first time interval is greater than the second time interval.
