Mobile terminal with multiple batteries
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.
1. A mobile terminal comprising:
first and second batteries for supplying driving power to the mobile terminal;
a display unit for displaying content to a user, the content indicating an operational state of the mobile terminal;
a user input unit for receiving a command from the user; and
a controller configured to:
control the display unit to display charged levels of the first and second batteries;
perform an inter-charging between the first and second batteries upon receiving the command from the user;
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.
2. The mobile terminal of claim 1 , 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.
3. The mobile terminal of claim 2 , wherein the controller is further configured to perform the inter-charging in response to the water levels in the vessel.
4. The mobile terminal of claim 2 , 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.
5. The mobile terminal of claim 3 , 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.
6. The mobile terminal of claim 4 , 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.
7. A method of operating a mobile terminal, the method comprising:
supplying, by first and second batteries, driving power to the mobile terminal;
displaying, by a display unit, content to a user, the content indicating an operational state of the mobile terminal;
receiving, by a user input unit, a command from the user; and
controlling, by a controller, the display unit to:
display charged levels of the first and second batteries;
perform an inter-charging between the first and second batteries upon receiving the command from the user;
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.
