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 happy to do it, but 1st a couple of questions:
1) Which radio do you want me to use (although I don't think it makes a difference
2) I'll test the long term voltage drop over a 1 or 2 hr period, using each method.
For quick short term answers, you can download "BATTLOG", and watch how much current it draws in each condition. The current is going to "bounce" around, but the higher the average number, the faster the battery will drain.
Just let me know which radio to use

For anyone interested, the battery program is Pocket Battery Analyzer

Cost $6.95
I recommend it as an excellent reference tool. If anyone knows of a different one, please let me know...I'd like to try it
