A servo system in a disk drive in a mobile device is responsive to an environment signal from the mobile device to generate a first current profile to a head actuator when the mobile device is docked and to generate a second current profile to the head actuator when the mobile device is mobile. The second current profile requires less power than the first current profile, thus reducing current drain on a battery in the mobile device.
