Guess-timating Battery Usage: wi-fi or 3G

[hakr100]

Just curious.

Let's say that I'm just using my droid as a normal cell phone, with a few calls out and a few calls in each day. Wi-Fi is off and 3G is off.

Let's call that (1) Ordinary Usage.

Now, let's turn on Wi-Fi for, oh, an hour of internet stuff at the local coffee shop.

Let's call that (2) Ordinary Usage + Wi-Fi.

Now, let's turn off Wi-Fi and turn on 3G for an hour of 36 usage.

Let's call that (3) Ordinary Usage + 3G.

Now, the question.

Assuming one starts with the battery at 100%, after a day of usage, what would be the battery percentage levels for

(1)

(2)

(3)

Has anyone done this? Is there an app that displays "base" and "base +" usage of the battery?

I'm led to believe WiFi uses less battery than 3g. But it would be nice to see some sort of accurate way of testing this via a decent app.
