Hi I have the same problem with my i9505, I got it second hand with 4.2.2 stock if I remeber correctly, I dont know if it was previously rooted but I flashed the latest stable version of Cyanogenmod 11 4.4.4 on it, then tried 2 different stock firmwares (current is stock I9505XXUGNG8) and that didnt change nothing. I charged it with a black Samsung charger 2.0A then tried an 2.1A ipad charger, I bought a new U2 Samsung microusb data cable. Still 8 to 9 hours for a full charge.
Did you find a solution to the problem?
