i know why battery life sucks so much!

What we should do is test our actual running times with different hardware usage. I've already done three tests. I don't have a lot of time right now, so I will just post a quick summary.

Full backlight + WiFi, 258 mA: Down to 20% in 5:39.
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.
