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.

First claim

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.

2. The mobile terminal of claim 1 , further comprising a wireless communication unit configured to communicate with an external terminal, wherein the controller is further configured to cause the wireless communication unit to transmit a first control signal for executing the content at the external terminal and terminate execution of the content at the mobile terminal when the selected content operating mode corresponds to a first content operating mode.

3. The mobile terminal of claim 2 , wherein the controller is further configured to resume executing the content when the battery swap mode is terminated.

4. The mobile terminal of claim 3 , wherein the controller is further configured to resume executing the content starting from at a first time point when the content execution was terminated in response to the first control signal.

5. The mobile terminal of claim 2 , wherein the controller is further configured to determine whether the external terminal is executing the same content as the mobile terminal.

6. The mobile terminal of claim 5 , further comprising a camera, wherein the controller is further configured to:
receive information via the wireless communication unit of a recording standby mode of the external terminal while recording a video via the camera of a first view angle which includes a first object;
detect whether a second view angle of a camera of the external terminal in the recording standby mode includes the first object;
cause the wireless communication unit to transmit a second control signal to the external terminal for starting recording of video of the first object at a first time point which corresponds to termination of recording video by the camera of the mobile terminal.

7. The mobile terminal of claim 6 , wherein the controller is further configured to receive recorded video data ending at a second time point from the external terminal via the wireless communication unit.

8. The mobile terminal of claim 7 , wherein the controller is further configured to resume recording video of the first object via the camera starting from the second time point when the recorded video data is received from the external terminal.

9. The mobile terminal of claim 8 , wherein the controller is further configured to cause the wireless communication unit to transmit a third control signal for deleting the recorded video data at the external terminal when the battery swap mode is ended.

10. The mobile terminal of claim 5 further comprising a microphone, wherein the controller is further configured to:
receive information via the wireless communication unit of a recording standby mode of the external terminal while recording specific audio via the microphone;
detect whether a microphone of the external terminal is capturing the specific audio in the recording standby mode;
cause the wireless communication unit to transmit a second control signal to the external terminal for starting recording of the specific audio at a first time point which corresponds to termination of recording the specific audio by the microphone of the mobile terminal.

11. The mobile terminal of claim 10 , wherein the controller is further configured to receive the recorded specific audio data ending at a second time point from the external terminal via the wireless communication unit.

12. The mobile terminal of claim 11 , wherein the controller is further configured to resume recording the specific audio via the microphone starting from the second time point when the recorded specific audio data is received from the external terminal.

13. The mobile terminal of claim 12 , wherein the controller is further configured to cause the wireless communication unit to transmit a third control signal for deleting the recorded specific audio data at the external terminal when the battery swap mode is ended.

14. The mobile terminal of claim 1 , wherein the controller is further configured to cause the display to change a content display screen of the executed content to a minimal version of the content display screen when the selected content operating mode corresponds to a second content operating mode.

15. The mobile terminal of claim 1 , wherein the controller is further configured to maintain execution of the content when the selected operating mode corresponds to a third content operating mode.

16. The mobile terminal of claim 1 , wherein threshold levels of the battery status corresponding to selection of different content operating modes vary based on the type of content being executed at the mobile terminal.

17. The mobile terminal of claim 1 , wherein the controller is further configured to cause the display to display an indicator indicating the mobile terminal being switched to the battery swap mode when a battery status of at least the primary battery or the secondary battery is less than or equal to a threshold level.

18. A method of controlling a mobile terminal, the method comprising:
executing content;
switching the mobile terminal to a battery swap mode while executing the content, wherein the battery swap mode allows for a primary battery of the mobile terminal to be uncoupled from the mobile terminal;
detecting a battery status of a secondary battery of the mobile terminal when the mobile terminal is switched to the battery swap mode;
selecting a content operating mode from a plurality of operating modes based on the detected battery status of the secondary batter;
sensing a residual quantity of a backup battery; and
determining a content operating mode based on the sensed residual quantity of the backup battery.

19. The method of claim 18 further comprising transmitting, to an external terminal, a first control signal for executing the content at the external terminal and terminating execution of the content at the mobile terminal when the selected content operating mode corresponds to a first content operating mode.

20. The method of claim 18 further comprising changing a content display screen of the executed content to a minimal version of the content display screen when the selected content operating mode corresponds to a second content operating mode.
