I don't know about it turning green all the time but it would be nice to have the plug back to see when it is sort of probably fully charged. The only way to know for sure is for me to go I to battery detective and see when it is finally starting to drain a little then I know it's done charging. It was kind of like this before on ios 6 but at least then it showed a plug once it was up to full capacity. Now it shows 100% even before it hits the full capacity. It will sit on 100% for up to 35-45 minutes till it's done trickle charging. When I wait this long after the supposed 100% fully charged I always have longer battery life.
