Power save mode

Currently i am setting sampleRate to 1e6, oversample to 2 (in order to get lock) and:
EnableChannel(true, 0, false);
EnableChannel(true, 1, false);
EnableChannel(false, 0, false);
EnableChannel(false, 1, false);
This provides reasonable power usage reduction.

Is there anything else i could try to save more power? While active my application uses only RX0, while “Power save” everything could be off.
