I tested this a while ago with my Neo1973, and the noise did get quieter 
as the RF level went down. I can't quantify this - it was just 
subjective observations.

The test was a cheap Radio Shack microwave leakage tester and the phone 
sitting next to each other on my desk (not moved during the test). I 
covered both of them with a metal mixing bowl to block some of the RF 
signal. After I removed the bowl, the RF level stepped down a few times 
(a couple of seconds between steps) and the buzzing got quieter at each 

I didn't look at the battery current. The Neo was transmitting audio 
throughout this test.
