Mobile terminal displaying remaining battery capacity and method thereof
First Claim
1. A mobile terminal comprising:
- a display unit for displaying remaining battery capacity information;
a battery detecting unit for determining whether an external battery is installed on the mobile terminal in a state in which an internal battery is installed on the mobile terminal;
a remaining battery capacity measuring unit for measuring total voltage of the internal battery and the external battery if the installation of the external battery is detected; and
a control unit for controlling display of total remaining battery capacity corresponding to the measured total voltage on the display unit differently from the remaining battery capacity corresponding to voltage of the internal battery.

Abstract
A mobile terminal device and method are provided for displaying remaining battery capacity. The device and method comprise internal and external batteries installed on the mobile terminal, a display unit displaying remaining battery capacity, a battery detecting unit identifying whether the external battery is additionally installed, a remaining battery capacity measuring unit measuring total recharged voltage of the internal and external batteries and a control unit displaying the total remaining battery capacity on the display unit corresponding to the measured total recharged voltage. Accordingly, a user may identify installation of the external battery more easily and avoid confusion due to rapid display changes in remaining battery capacity displayed as a recharged voltage difference between the internal and external batteries.
