It is possible to provide a mobile electronic device which can accurately and clearly display a cell service life and a method for controlling the device. The mobile electronic device includes: a charge cell (32); a voltage measuring unit (system IC 64) which is connected to the charge cell (32) and measures a voltage of the charge cell (32); an output unit (display 21) which outputs various information; a memory (63) which stores a weighting value for each of voltage values; and a control unit (system IC 64) which measures a voltage of the charge cell (32) by the voltage measuring unit upon each start and end of charge of the charge cell (32), extracts a weighting value corresponding to the measured voltage value from the memory (63), successively adds the extracted weighting values so as to identify information on a number of charge times, and stores the information in the memory (63). The control unit causes the output unit to output information on a service life of the charge cell (32) according to the information on the number of charge times stored in the memory (63).
