1. A method for estimating charge consumed when receiving bursts of data at an electronic device, said method comprising the steps of:

  • incrementing at least one counter each time a data burst is received;

    reading at least one value from a memory, the at least one value representing an estimate of a charge consumed during reception of a burst;

    reading a value from the at least one counter, the value representing a number of bursts received since a calculation of a previous battery power estimate;

    multiplying the value read from the counter with the value read from the memory to produce an estimated charge consumption; and

    updating said previous battery power estimate using said estimated charge consumption to produce an updated battery power estimate.
