1. A mobile information device comprising:
- a power source;
an operation unit which detects a mobile device operation by the user,a detection unit which detects a user handholding state of the mobile device according to a probe current measurement based upon the user, when the mobile device is operated by the user according to the mobile device operation; and
a control unit which controls such a transition point as to transit from a first state to a second state in accordance with whether the user handholding state is detected,wherein said control unit cuts off said power source when said operation unit does not detect the mobile device operation by the user for duration of a first period in the user handholding state, and also cuts off said power source when said operation unit does not detect the mobile device operation by the user for duration of a second period if not in the user handholding state.
