Abstract:
A method for reserving and using reserve power in a mobile radio communication terminal, said terminal including a plurality of functional units and a power supply unit, wherein the power supply unit is the sole common electrical charge storing unit for use by the functional units, said method comprising the steps of:sensing an electrical charge level of the power supply unit;generating a reference signal for indicating whether reserve power in the electrical charge storing unit is to be reserved or used by selecting a first reference signal level for the reference signal if the reserve power in the electrical charge storing unit is to be reserved and selecting a second, lower reference signal level if the reserve power is to be used;comparing the electrical charge level to the reference signal; andallowing operation of the terminal if the electrical charge level is higher than the reference signal.
