Mobile terminal and method for controlling the same

1. A mobile terminal comprising:

a wireless communication unit configured to provide wireless communication;

a display;

a battery configured to supply power to the mobile terminal; and

a controller configured to:

measure a remaining charge of the battery when a pre-notice mode is activated,

measure an available time of the battery based on the measured remaining charge of the battery and a load of the mobile terminal, and

output a predetermined pre-notice event when an upcoming scheduled event is present after the available time,

wherein the pre-notice mode is activated via an input for an item for setting the pre-notice mode included in a schedule setting screen for inputting a new event,

wherein the schedule setting screen is displayed when a new schedule menu is selected, and

wherein the controller is further configured to determine a priority of the scheduled event by using a schedule information input through the schedule setting screen, and as the priority of the scheduled event increases, increase a threshold of a remaining battery power corresponding to a condition for occurring of the pre-notice event.

2. The mobile terminal according to claim 1 , wherein the controller is further configured to receive preset schedule information according to a user input.

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

check whether a specific time when the pre-notice event can be generated is reached based on a predetermined schedule time and a pre-notice time, and

measure the remaining charge of the battery when the specific time is reached.

4. The mobile terminal according to claim 3 , wherein the pre-notice time is set by a user upon setting schedule information, upon setting a pre-notice alarm mode or is set by default by a manufacturer of the mobile terminal.

5. The mobile terminal according to claim 1 , wherein the controller is further configured to output the pre-notice event when the measured remaining charge of the battery reaches a predetermined threshold.

6. The mobile terminal according to claim 1 , wherein the controller is further configured to display, on a status bar of the display, a pre-notice icon indicating that the upcoming scheduled event is present after the available time.

7. The mobile terminal according to claim 6 , wherein the controller is further configured to display, on the display, a pre-notice screen including information on a scheduled event to be pre-notified and an operation option of a user related to pre-notice, in response to pre-notice information corresponding to the pre-notice icon being selected.

8. The mobile terminal according to claim 1 , wherein the controller is further configured to output pre-notice events having different levels according to a state of the battery.

9. The mobile terminal according to claim 1 , wherein the controller is further configured to output the predetermined pre-notice event when an upcoming alarm is present after the available time.

10. A method of controlling a mobile terminal, the method comprising:

supplying, via a battery of the mobile terminal, power to the mobile terminal;

measuring, via a controller of the mobile terminal, a remaining charge of the battery when a pre-notice mode is activated;

measuring, via the controller, an available time of the battery based on the measured remaining charge of the battery and a load of the mobile terminal; and

outputting, via the controller, a predetermined pre-notice event when an upcoming scheduled event is present after the available time,

wherein the pre-notice mode is activated via an input for an item for setting the pre-notice mode included in a schedule setting screen for inputting a new event,

wherein the schedule setting screen is displayed when a new schedule menu is selected, and

wherein the method further comprises determining a priority of the scheduled event by using a schedule information input through the schedule setting screen, and as the priority of the scheduled event increases, increasing a threshold of a remaining battery power corresponding to a condition for occurring of the pre-notice event.

11. The method according to claim 10 , further comprising:

receiving preset schedule information according to a user input.

12. The method according to claim 10 , further comprising:

checking whether a specific time when the pre-notice event can be generated is reached based on a predetermined schedule time and a pre-notice time; and

measuring the remaining charge of the battery when the specific time is reached.

13. The method according to claim 12 , wherein the pre-notice time is set by a user upon setting schedule information, upon setting a pre-notice alarm mode or is set by default by a manufacturer of the mobile terminal.

14. The method according to claim 10 , further comprising:

outputting the pre-notice event when the measured remaining charge of the battery reaches a predetermined threshold.

15. The method according to claim 10 , further comprising:

displaying, on a status bar of a display of the mobile terminal, a pre-notice icon indicating that the upcoming scheduled event is present after the available time.

16. The method according to claim 15 , further comprising:

displaying, on the display, a pre-notice screen including information on a scheduled event to be pre-notified and an operation option of a user related to pre-notice, in response to pre-notice information corresponding to the pre-notice icon being selected.

17. The method according to claim 10 , further comprising:

output pre-notice events having different levels according to a state of the battery.

18. The method according to claim 10 , further comprising:

outputting the predetermined pre-notice event when an upcoming alarm is present after the available time.
