Is it? There is no lithium battery out there that doesn't have a discharge slope that just falls off at the edge under high load. The alternatives are: - stop powering the device when the charge gets into the zone where sudden dropouts might happen (i.e. lose about 5% capacity) - accept sudden dropouts and have users experience devices that suddenly fail (i.e. lose about 5% of their useful charge since you can no longer depend on the device being on)
