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 (d) 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 (d) of the battery; determine a full charge capacity correction factor value (C) associated with the battery; determine a weighting factor (&#x3b1;); determine a difference between a full charge capacity value (FCC) and C; determine &#x3b1;&#xb7;d; determine (1&#x2212;&#x3b1;)&#xb7;d; determine a sum of d&#xb7;&#x3b1; and d&#xb7;&#x3b1;; determine a quotient value of FCC&#x2212;Cand &#x3b1;&#xb7;d+(1&#x2212;&#x3b1;)&#xb7;d; 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.

System and method of estimating time remaining for an information handling system to operate on electrical power provided by one or more batteries

The measured capacity of a rechargeable battery provides the full charge capacity of the battery, but does not reflect degradation of the battery capacity between measurements. Embodiments initiate a first measurement of a rechargeable battery capacity. Parameters of use of the rechargeable battery are monitored, such as the depth and number of discharge cycles of the battery. Until a second capacity measurement is initiated, a battery capacity correction factor is generated based on the monitored parameters of the use of the rechargeable battery. During this interval until the second measurement, a remaining available capacity of the rechargeable battery is reported based on an adjustment of the first capacity measurement using the generated correction factor. The correction factor for a particular battery may be based on learned battery degradation for a large number of batteries and also based on events and conditions of use of that particular battery.
