Hi guys, this may be a possible solution:
I have narrowed the problem down to the actual charging cable that you use.
I too have an S3, which used to charge super slow, so what i did was the following:
- borrowed my brothers S3 charging cable to check if that makes a difference; tried it, no difference at all!!
- used my HTC ONE SV cable, and it worked!!

- i use a battery charging monitor for the phone, while using the original s3 charging cable, id get a reading of 200 to 300 ma provided to the phone, but when i used the HTC cable the reading shot up to 1000 ma, in other words 1A, i know this monitor isn't 100% accurate, but it tells you that there is a difference made when you change the cable.

- Also, when you look at the S3 charging cable's micro-usb port, it only consists of 4 golden pins, but the HTC cable has 5 pins, so the extra pin may make a difference.

WARNING: do not throw away your original S3 charging cable because that is the only cable you can use to sync your S3 with your computer.

You tried to see if you're using correct charger? If your phone requires a 1.2a but are using a 1a charger, speed of charge will drastically go down. Also if you're using an extender, or a ****tier quality cable, it will slow down the charge. I use a 1a charger with an extender to the original USB cable while charging overnight and it takes about 6 hours to fully charge. This is an advantage cause it charges slowly and battery temperature stays low.
