Systems and methods manage use of rechargeable battery power of Information Handling Systems (IHSs). In managing power draws from the batteries of an IHS, use of software applications of the IHS is monitored and use is detected of a software application that has been designated as prioritized for use of the IHS batteries. A power throttling factor is selected for use in drawing power from the rechargeable batteries of the IHS while the prioritized software application remains in use. The selected power throttling factor is transmitted to an embedded controller of the IHS and the embedded controller is notified when the prioritized software application is no longer in use by a user of the IHS. The embedded controller receives the power throttling factor and, while the prioritized software application remains in use, the embedded controller limits power drawn from the IHS rechargeable batteries according to the power throttling factor.
