Upgraded to the Stylo 2 recently only to find that it charges absurdly slow. When it's not in use, the Stylo 2 charges in about 3 hours which is decent. However, when the screen is on, the estimated charge time shoots up to 9 hours. It'll often take 10-20 minutes to go up 1 percent. I am definitely sure it is neither the AC Adapter nor the wire as they both once charged my original stylo quickly and still continues to charge my old Galaxy SIII quite fast. Does anyone else have this problem?
