Hi!Maybe you using usb cable which not support fast charge?Try use original cable and adapter from box

If your phone can be fully charged in up to 3 hours when is switched off this is indicating that hardware working correctly and you have some system bug. In this situation please perform factory reset and check for updates.
Otherwise you have hardware issues as USB port or USB cable. Please check USB port and USB connector for any damage and alien objects.

Also please open calling dialler and type in *#*#33#*#* go to single test - battery and check charging voltage. When is charging fast should be at around 12V. Also you can install 3c battery widget and check charging current which should be around :
