You order a cheap cable off Amazon or eBay and it never appears to charge at the correct speed anymore. USB chargers can impact how fast your device's battery gets back to 100%, but they're not the only determining factor. The wrong cable can slow down charging speeds as well. Redditor Esteef explains. 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 when it charges, maybe even less.
As the temperature increases, some electrons move from valence band to conduction band. This gives rise to the conductivity. But, as the number of charge carriers are very low, covalent compounds are poor conductors.

Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of any commonly known material. Most of the best conductors of electricity are metals. The best conductors are silver, gold and copper, while the worst are mercury and certain alloys of stainless steel. As a general rule, elements with a single valence electron are better conductors than those with more.
