The result is exactly the same as the original Samsung (23awg @ 1m) usb2 cable with the original wall charger. Both charge at 1800-1900mA.

Using a Samsung wall charger rated at 2.1A (the supplied charger with my sm-g900i) and a 1m usb2 cable with a 23awg gauge (again, the same cable supplied with my phone), I am able to charge my phone at 1900mA. If I use a cheap 1m small gauge cable (32awg) the phone will draw ~900mA.

I've measured the current using a multimeter.

So, I have no idea what it is that you're disagreeing with or have trouble comprehending but with respect to the difference of using an (appropriately rated) usb2 and a usb3 cable plugged into a wall charger purely for charging purposes - THERE IS ABSOLUTELY, POSITIVELY, UNQUESTIONABLY NO DIFFERENCE!

Just to alleviate any further confusion on your part...

The 5 pins on the right pertain to a micro usb2 cable pin-out. The 5 pins on the left pertain to the additional data transmission pins for a micro usb cable. There are no additional power pins on the left, there is a 5v power and ground pin on the right which is common to both a micro usb2 and micro usb3 cable.

Case closed.

There is no difference in charging speed due to the cable. It depends on the charger. Connected to a computer it makes a huge difference, at least on mine. When phone is in usb 3.0 mode, it charges 4 x faster than in usb 2.0 mode.

sorta correct. there is no difference in usb 3.0 or 2.0, if your computer only sends 750ma when it detects 2.0 and 2.1a when it detects 3.0 then of course it will charge differently. but not because of 3.0 or 2.0 but because of your computer. my pc charges 2.0 and 3.0 at the same 2.1 amp on a high output usb, so it makes no difference.

it depends on the mb to what ampage it will supply.

my asus board for example supplies enough to charge gs5 properly but i couldnt tell you what exactly

Maybe that's the case on your computer, but not on mine. In USB 2.0, the computer is supplying 96 ma. In USB 3.0, the computer is supplying 384 ma, which is 4x as much, as I stated previously.

LOL, that's crazy... There's something seriously wrong with your computer then...

A usb2 port should supply 500mA while usb3 should supply 900mA.

Your kernel can also set charging speed and pull. See KT settings for fast charge. To use an analogy the theoretical charging speeds are the same. If your computer or power source limit the supply that's another issue altogether.
