Full backlight + WiFi + GPS, average of 464.33 mA: Down to 20% in 2:59.
Full backlight + All radios + GPS, 535 mA: Down to 20% in 2:30.
(All other hardware, including the cellular radio, was off unless I stated otherwise.)
If you do the math, you'll see that my battery actually lasts a little longer than it should! However, this is assuming that the calculated (not sensed) discharge current values are accurate.

A good suggestion, but I will find it hard to allocate time to do all three. I have just embarked upon a different test, in hopes of pinning down why my Bluetooth connection draws so much power. The Ma readings tell me that I should not lose 10% per hour when Bluetooth is On. So my plan is to turn all radios off except Phone and Bluetooth. I will not pair the Bluetooth during the test and I will monitor the discharge rate periodically by turning the screen on. If I receive any calls during the test period I can adjust for that because I have learned to expect a discharge due to phone use of approximately 20% per hour. At the end of an 8 hour period, I will have learn something, I hope. The phone is charging now.
