Maybe you two can comment on this:
I wonder, does anyone have the HD ROM/Radio decomplied/dumped, yet? Take a look at these specs:
Stand-by Up to 450 h
Talk time Up to 6 h 30 min
Maybe they fixed the issue in this device? This device is using the exact same chipset, and the display is larger. Even though the device is without the keyboard, it is obviously not connected, since some people can reproduce an issue without using their phone.
I'd suggest taking a look in that Radio, and ROM, and see what differences there are, set aside from the newer build of TouchFlo3D, and the drivers and Windows Mobile files being for WVGA.

I have not seen a ripped radio rom off the HD, and I am not sure how much help it would be as it is driving a different transmitter chipset.

There are plenty of other devices that don't use the Quailcom chip set and they have the same type of battery issues which leads me to believe that this is a universal issue not just a Quailcom HTC issue. Could it be that the radios GSM or CDMA just uses a lot of power no matter what device it is? I appreciate you knowledge and hard work in testing this, I hope that there is something that can be done but I am skeptical. The bottom line and root of the discussion is, is this a defect or just the way it is? IMHO it is not a defect, we will have to learn to live with it for now.

One interesting thing to note is that the Qualcomm RFT6150 is one of the most popular CDMA Trasmitter chips used in a plethora of low to high range LG and Sanyo devices as well as the HTC devices since the release of the MSM7200 platform in '05. So if it were just the transmitter device, I would expect heat and battery issues with those phones (LG and Sanyo) as well, (I did a quick google search and didn't come up with much there). I was finally able to put my hands on an application sheet for the MSM7501A.
I may have been a bit off base on blaming it entirely on the modem (and the radio ARM Processor). One thing I learned from the MSM 7200 and MSM7500 data sheets is that they both use the PM7500 power managment module. This module controls all aspects of battery and power managment for the entire phone (including charging and thermal managment). Although the information I have found on it is limited, It may very well be an issue with it.
I have made a couple of inquires on configuration/programing of the PM7500 and will chime in when I get the information. But it is quite interesting that many of the issues that are common compaints for this and previous devices are all controlled by the PM7500. Below is a list from the Qualcomm site of what the device controls. (hope that this hasn't muddied the water too much...)
