A mobile electronic device is disclosed. A first display module comprises a first touch panel, and a second display module comprises a second touch panel. A battery supplies power to the first display module and the second display module, and a detection module determines whether the first touch panel and the second touch panel are viewable by a user. A setting module sets the first touch panel to a first brightness, if the battery level is below the first value and if the second touch panel is not viewable (non-viewable) by the user. The setting module sets the first touch panel and the second touch panel to a second brightness darker than the first brightness, if the battery level is below the first value and if the second touch panel is viewable by the user. |
