I am trying to figure out, for a constant data stream, like when streaming music or youtube videos, does it use less battery to stream over EVDO, or over wifi? Lets assume a good EVDO signal, 3-4 bars, and for the wifi, being very close tothe router, 10-20 feet with a clear line of sight.
I *seem* to get slightly better battery life over wifi, but both methods drain battery very quickly and cause the radio to heat up a lot (I took the back cover off.... the battery was not the main source of the heat). I would love to have some hard data though to know which method is better for battery!

I'll be looking at CNN News on the MediaPlayer. Bob

Initial Results from WIFI operation - Other than the phone itself, the following items were turned used: Pocket Streamer and WM Media Player. The only other active item is that the TP was operating at FULL BRIGHTNESS....so if you use a dimmer screen, the battery will last longer.
The sawtooth pics of the current are normal....gives the chips a few milliseconds to cool off rather than run at a constant rate.
Pic 18 shows the current draw.
Pic 19 - Battery Drain in the WIFI mode (Data connection OFF entire time)
I'll finish the EVDO test after recharging, and will edit this post to include the results.
Edit 2: Added EVDO test. Same config as above..Except EVDO is the one turned on. I have no explanation why the current graphs #18 and #21) are so much different. Run basically under the same conditions
