Confirmed all of these issues with Samsung. Mine is from T-Mobile
Have Verizon version, black, wanted to test this theory so I used a generic $5.00 charger from Big Lots (low-end retailer in the US) for "Samsung Phones".
From a full charge, turned brightness to max, added a live wallpaper and left the screen on. Then I ran it down to 98%, plugged in el-cheapo charger, left the screen on. 5 - 10 minutes later, voila, back to 100%. Didn't wait for the green light. Put it back in my Note 2 dock, which will turn the LED green when the battery is full, and indeed, it is full.
