20100050009BATTERY VOLTAGE SAF AVOIDANCE ALGORITHM FOR A WIRELESS HANDHELD DEVICE - A method and system for power source management of a portable device, A power source used to supply electrical energy for a portable device should ideally operate with a constant terminal voltage. However, the terminal voltage of a cell or group of cells used as a source of electrical energy can be expected to reduce in amplitude over its operational lifetime. Near the end of operational lifetime, the terminal voltage of such a source can be expected to decrease rapidly. Furthermore, the source terminal voltage will also exhibit significant variations in amplitude in response to changes in electric current demands on the source.
