ABSTRACT:
Battery current is indicated on a display element of a portable computing apparatus. Real time changes in battery current show the effects on the battery for given operations and configurations of the computing apparatus. The battery current is displayed as an icon. In various embodiments the icon indicates an absolute battery current value (e.g., in ampere or micro-ampere units), or a relative battery current value (e.g., a percentage relative to a predetermined reference current level). The icon appears on a display screen of the computing system or is a built-in dedicated indicator mounted into the apparatus case. A battery charge icon accompanies the battery current icon.
