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.
