Dynamic reduction of current drain for antenna tuner of a communication device

A communication device, method and computer program product provide improved performance of one radio frequency (RF) conduction path using an antenna tuner of another RF conduction path while dynamically reducing current drain by the antenna tuner. A determination is made that a first RF conduction path is active in using a first portion of a multiple band antenna system for at least one of: (i) transmitting; and (ii) receiving a signal. An antenna tuner of a second RF conduction path that uses a second portion of the multiple band antenna system is activated. The antenna tuner is configured to tune the second portion of the multiple band antenna system to isolate the second portion from the first portion used by the first RF conduction path. The antenna tuner is deactivated in response to determining that both the first and second RF conduction paths are inactive.
