Actually PTBoater, there's a bit more to this sadly-obsessive "green glow" yarn... The 411 is, from the "glow initiated crowd", is that you only get the real glow when that last sliver on the right is gone, the whole battery is green and the "charged" plug icon appears in the center of the green battery. At that point, and only at that point, will the green battery glow more brightly than before. Kind of like the most holy of grails. I kid you not...
'-)
I tried to convince them that it was only a bug, that didn't actually affect the charge of the iPhone (only the indication on the screen), but they shooed me away for being a non-believer.
...And that's the whole 411 on the infamous green glowing battery.
All you kids to bed now...
