My guess for the WiFi/EVDO is that those items just tell the radio how to get the info...In either case, you are not turning on another piece of hardware...The phone is always active....so it's just dialing #777. The wifi connection still has to get in thru the antenna and probably passes thru the radio that sorts it all out. I tried putting the phone in the "airplane" mode to turn it off, but it also turned off the WiFi connection, so it couldn't be tested in that fashion.
Don't know how correct I am in those assumptions, but after a couple of beers, they sound reasonable.
That's why I think alot of this battery improvement with the different radios and connections is "imaginary". Every test I have run gives nearly the same results IF THE CONDITIONS ARE KEPT CONSTANT.

Hi Bob, I really appreciate your testing...it's a royal pain in the arse to do that kind of stuff and I really appreciate it.
I'm not arguing your observations at all, but I just don't think your theory explaining them is quite accurate. From what I know of PC hardware some of it just doesn't quite jive. IC chip power usage, in general, can fluxuate a lot based on the task it is doing...especially multifunction ones like motherboard chipsets. Just because the 7500A is handling everything, it is not safe to assume the power draw will be similar.
This is mainly aimed at your radio tests. I agree with you, I think a lot of people have a placebo effect going with the 1.11 radio...you've put up a variety of numbers showing no difference, so I'm inclined to believe them over casual observation. What I do disagree with is that you seem to think no radio revision will ever make a difference because it is just software. I think it could, and this is why:
While just software (or firmware as I would imagine it is closer to) the radio software is what tells the radio chip to do anything. If it's telling it to scan for better towers, or sending data for transport, it is giving commands to the radio chip. Bugs or inefficiencies in the radio software could affect the battery and signal performance, by either not switching to another tower, sending erraneous data packets, etc. So newer versions could fix or improve upon old ones.
Basically what I'm getting at is don't stop testing
I think a future radio version could make a difference, and the kind of testing you do will prove it definitively.
