Mobile terminal and controlling method thereof

Abstract

Disclosed are a mobile terminal and controlling method thereof. The present invention includes a battery unit including a main battery and a backup battery, a sensing unit, a display unit, and a controller configured to sense a residual quantity of the backup battery if entering a battery swap mode in the course of running a content, wherein the battery swap mode comprises a state that the main battery is separated from the mobile terminal and wherein the controller is further configured to determine a content operating mode based on the sensed residual quantity of the backup battery.

What is claimed is: 
     
         1 . A mobile terminal, comprising:
 a primary battery and a secondary battery;   a display; and   a controller configured to:   detect a battery status of the secondary battery when the mobile terminal is changed to a battery swap mode while executing content; and   select a content operating mode from a plurality of operating modes based on the detected battery status of the secondary battery;   wherein the battery swap mode allows for the primary battery to be uncoupled from the mobile terminal.
