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?
