Color circle battery when charging

[chenasraf]

While the rotation animation is pretty and all, it's hard to notice from afar or at a glance, whether the phone is charging properly from looking at it. Especially with little to no battery charge, when the bar is significantly smaller. I'd love to be able to have it green for example, or maybe surrounded with a small outline, so that we can look at it with a glance. I always have to wait 3-4 seconds to notice if it's turning, or put the phone closer.

Thanks!
