Have you guys try this?
Guys I was having the same issue with the charger that came with the phone, sometime is fast charging and other just regular, I found a work around, if you plug the phone to the cable and is not fast charging, leave the cable plug to the phone, unplug the cable from power terminal and then plug it back in, it will start charging fast, the key is not to remove the cable from the phone and the leave power connected to the outlet, only removing the cable from the terminal, I thought my cable was bad, but found that works around. Let me know if it work for you
