Abstract

Embodiments of the present invention are related to a mobile terminal, the mobile terminal including: first and second batteries for supplying driving power to parts of the mobile terminal; a display for displaying an operational state of the mobile terminal to a user; and a controller for notifying the user of charged levels of the first and second batteries.

Claims

1. A mobile terminal comprising:

first and second batteries configured to supply driving power to the mobile terminal;

a display unit configured to indicate an operational state of the mobile terminal to a user; and

a controller configured to control the display unit to display charged levels of the first and second batteries.

2. The mobile terminal of claim 1, wherein the controller controls the display unit to display the charged levels of the first and second batteries using two battery icons in an indicator area.

3. The mobile terminal of claim 1, wherein the controller is further configured to:

control the display unit to display the charged levels of the first and second batteries using electrode images each having an anode and a cathode; and

control the display unit to indicate use, charging and status of the first and second batteries using a direction toward which the anode of the respective electrode image protrudes.

4. The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to display a first user interface screen when the mobile terminal is operating under a normal mode and to display a second user interface screen when the mobile terminal is operating under an emergency mode, wherein the second user interface screen is simpler than the first user interface screen.

5. The mobile terminal of claim 1, wherein the controller is further configured to control the mobile terminal to operate under an emergency mode if the mobile terminal is positioned at a designated location.

6. The mobile terminal of claim 4, wherein the controller is further configured to control the display unit to display a mode set-up window for selecting functions to be activated in the emergency mode.

7. A mobile terminal comprising:

first and second batteries for supplying driving power to the mobile terminal;

an display unit for displaying content to a user;

a user input unit for receiving a command from the user; and

a controller configured to inform the user of charged levels of the first and second batteries, and to perform an inter-charging between the first and second batteries upon receiving the command from the user.

8. The mobile terminal of claim 7, wherein the controller is further configured to control the display unit to indicate the charged levels of the first and second batteries using graphical representations of water levels in a vessel, the water levels corresponding to the charged levels of the first and second batteries.

9. The mobile terminal of claim 8, wherein the controller is further configured to perform the inter-charging in response to the water levels in the vessel.

10. The mobile terminal of claim 7, further comprising:

a motion sensor for detecting a movement of the mobile terminal,

wherein the controller is further configured to perform the inter-charging in response to a tilting of the mobile terminal detected by the motion sensor.

11. The mobile terminal of claim 7, wherein the controller is further configured to inquire of the user whether a charge-completed battery is to be designated as a main battery, if charging of one of the first and second batteries is completed.
