PROBLEM TO BE SOLVED: To detect deterioration of a battery with high precision in an electronic apparatus which is driven by a battery and performs specific operation, and a power consumption measurement support system for measuring power from this battery. SOLUTION: The electronic apparatus fitted with a plurality of devices and the battery for supplying currents to these devices respectively attached or detached, is provided with a storage means which stores a current from the battery in each mode, a control means which controls currents to the devices from the battery respectively according to each mode, a time measuring means for measuring the duration of each mode, during an interval until the voltage of the battery decreases from the first voltage to the second voltage, and a deterioration detecting means which detects the deterioration of the battery by the comparison of the sum of the product of the measured duration of each mode and a current value of each mode stored in the storage means with a specified value. |
