Default S3 not showing charging current and charging slow

I'm trying to find the charging current on my phone but despite whatever app I use, it doesn't tell me. I want to find out the current because I believe that my phone is charging too slowly (It takes a hour to charge 10%, and it drains when I'm using the phone and charging simultaneously).

Whenever I try to use any current detecting app, it says NaN or Null. People said to go to /sys/class/power_supply/battery/current_max to see the current, however when I check, there's nothing there.

I'm using stock 4.4.2 android and I'm using KToonsez's most recent kernel.

The S3 is not capable of reporting current.
