1. The rechargeable user equipment comprising:
- a charging circuit configured to charge a battery at a maximum charge rate or a decreased charge rate, the charging circuit comprising an input adapted for connection to a charging device;
a motion sensing circuit for sensing non-movement of the rechargeable user equipment;
an audio sensing circuit for sensing a sound level about the rechargeable user equipment;
a processor, connected to the charging circuit, the motion sensing circuit and the audio sensing circuit, the processor configured to;
enable a user of the rechargeable user equipment to set an alarm clock function to alarm at an alarm time;
determine whether the charging circuit is receiving power at the input;
determine whether the motion sensing circuit has sensed non-movement for a predetermined non-movement time; and
determine whether the audio sensing device has sensed that the sound level has been below a predetermined decibel level for a predetermined quiet time;
when the set time is more than a delta time in the future, the processor provides a decreased charge rate signal to the charging circuit when power is being received at the input, non-movement has been sensed for the non-movement time, and the sound level has been below the predetermined decibel level for the predetermined quiet time, otherwise the processor provides a maximum charge rate signal to the charging circuit.

Abstract
A rechargeable mobile terminal is provided that provides a maximum charge rate of a rechargeable battery during active user hours of the day and provides the potential for applying a decreased charge rate of the rechargeable battery when the mobile terminal determines that the user has set the alarm clock function of the mobile terminal and that the time between the present time and the set alarm time (the delta time) is greater than an amount of time required to charge the rechargeable battery at a maximum charge rate.

8. A method of charging a battery in a user device comprising:
-
sensing, by a charging circuit in the user device, that the charging circuit is receiving power from an external power source; and determining, by a processor, whether a user set alarm clock event will occur more than a minimum charge time of the battery in the future; and wherein when the user set alarm clock event is determined to occur more than the minimum charge time of the battery in the future, then charging the battery by the charging circuit at a reduced charge rate, the reduced charge rate being from 1 to 99 percent of a maximum charge rate, otherwise charging the battery at the maximum charge rate. - View Dependent Claims (9, 10, 11, 12, 13, 14)
