I'm not sure I really trust these results as absolute, but relative might provide some insight. I used a kill a watt P4460 using the *current* measurement setting Adaptor only (not plugged into radio): 0.00A **less than 10ma Adaptor powering radio during bootup: 0.01 - 0.05 **0.01 at initial splash screen, 0.03 during boot, 0.05 when you can hear the audio amp power up (that subtle click) Radio Idle with clock screensaver 0.05 Radio Playing a FLAC file 25-75% volume 0.05 - 0.06 **I don't trust this. I changed over to wattage (120vac) and it was 3.5w @ 0% Vol, 4.3 @ 75% volume Radio power off (press and hold, blank screen) 0.00A So, if these are to be believed, there is about a 50 ma draw @ "off with clock" and <10ma draw at "press and hold off", 40ma difference So, lets assume it's a 40ma difference, I think the battery is 2000maH, that's only 50 hours, so something is wrong... I guess the one observation that might be trusted is that there is a difference between press and hold off and clock off. I think the issue with the test is measuring the ac power to the adaptor rather than the DC in line with the battery.
