Don't know about you but my S5 chargers incredibly fast compared to my SIII and Nexus 7. Even with fast charge on.

I use an app which reports charging current. With a standard micro usb cable i never morw than 1200 mA (and about 450 mA from a PC/mac usb plug)

It already charges from under 10% to 100% in a mere 2 something hours (bundled charger and USB 3 cable). You want something much faster than that???

While it's true that the phone ships with a 2A charger, the charging current does not exceed 1.2A AFAIK.
Yes I think in the end it is something around this current. What the apps report is more "charging in 1800mA mode" and not really charging with continous/real 1800mA. If you like to know more exactly what the current is you may write down time/percentage values for e.g. every 5% of battery power starting with an nearly empty battery. Then you can draw an line of the effective loading current.

With the original charger you should be able to get stable 1800mA but if the loading circuit of the S5 really goes this high I did not check.

Sorry to awaken this post.
As most of you, my S5 reported charging at stable 1200 mA with wall charger, probably 1800mA when turned off.
But, I can say a custom rom unleash battery charging in the same conditions as stock rom. I get stable 1800 mA with LineageOS, even screen on, with original charger and usb 2 or usb 3 cable.
