Check out this cable, I remember it was popular on this subreddit. http://www.amazon.com/gp/aw/d/B00WJE31QK/ref=mp_s_a_1_7?qid=1441949407&sr=8-7&pi=AC_SX110_SY165_QL70&keywords=micro+usb+cable+10ft&dpPl=1&dpID=31ynDmfEZZL&ref=plSrch

I have the same case, but on the regular S6 I will be buying myself this cable soon as my original one started to rip.

I'm not sure if it supports quick charge or not, but I love these cables. They are long as shit, don't tangle, and look nice:
