1. A method for calculating a consumed charge Q referred to a period Δ
- t in a mobile device with mains-independent power supply configured to be in different system states in the period Δ
t, comprising;
determining a period of a receiving/transmitting state in which the mobile device is in a transmitting state or in a receiving state in the period Δ
t;
reading out a stored predetermined current value for a current of the receiving/transmitting state from a memory, wherein the stored predetermined current value read out from the memory is dependent on at least one of supply voltage, temperature or component tolerances; and
multiplying the stored predetermined current value with the determined period in order to calculate the consumed charge Q for the receiving/transmitting state occurring in the period Δ
t.

Abstract
A method for calculating the power consumption of a mobile device, particularly of a mobile station of a mobile radio system, in an observation period Δt based on various possible system states sk in which the device can be in the period Δt. A value of a quantity Δk is determined system-state-dependently for the system states sk occurring in the period Δt. The power consumption in the period Δt is calculated in such a manner that the quantities Δk and state-dependent typical currents ik are taken into consideration.
