Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing a user with feedback regarding power consumption in a battery-operated electronic device. In one aspect, a method performed by data processing apparatus includes identifying, using the data processing apparatus, usage of a hardware component of a battery-operated electronic device that includes the data processing apparatus, attributing the usage of the hardware component to the hardware component or to a software application that uses the hardware component, recording, using the data processing apparatus, a power consumption resulting from the usage, and presenting power consumption feedback to a user using the data processing apparatus. The power consumption feedback identifies the hardware component or the software application of the electronic device and the power consumption resulting from the usage.
