Abstract
In one or more embodiments, one or more systems, one or more methods, and/or one or more processes may determine a historical discharge rate (dh) from multiple discharge rates a battery of an information handling system (IHS) while the IHS operates on electrical power provided by the battery; receive a current discharge rate (dc) of the battery; determine a full charge capacity correction factor value (Cfcc) associated with the battery; determine a weighting factor (α); determine a difference between a full charge capacity value (FCC) and Cfcc; determine α·dh; determine (1−α)·dc; determine a sum of dh·α and dc·α; determine a quotient value of FCC−Cfcc and α·dh+(1−α)·dc; scale the quotient value based at least on a relative state of charge of the battery to determine an estimated time remaining for the IHS to operate on the electrical power provided by the battery; and display the estimated time remaining.
