This article claims that wire gauge in USB cables significantly impacts the charging rate of smartphones:
USB cables have a data wire and a charging wire within the cable itself. Most USB cables, probably over 99+% are 28/28. Buying after market micro USB cables will pretty much always result in getting cheap quality 28/28 cables and your device will barely break 500mah [sic] when it charges, maybe even less.
The misuse of units makes me skeptical of the claims made by the article. Furthermore, the length of cables should also impact the total resistance, and the article does not mention cable lengths at all.
Is the article correct in saying that increasing the wire gauge from 28 to 24 (which has ~40% the resistance) would allow the charging current to increase from 500mA to 2A?
