1. A computer implemented method comprising:
transmitting an energizing signal from an external antenna, coupled to a local external device (LED), to an implanted antenna of an implanted medical device (IMD), the energizing signal transmitted while the external antenna is at first and second positions;
receiving, at the external antenna, first and second energy transfer characteristic (ETC) values associated with the first and second positions, respectively;
under control of one or more processors configured with program instructions,
analyzing the first and second ETC values to determine a change therebetween over a select time interval;
estimating a current level of available power of the IMD based on at least a predetermined value of power consumption of the IMD for at least one IMD operation and the change between the first ETC value and the second ETC value over the select time interval; and
initiating or delaying a select IMD operation based on the current level of available power of the IMD.
