I just bought the Aukey Turbo Charger PA-U28 off Amazon in an attempt to improve my battery charging times. With the normal OEM charger supplied with the phone it used to take around 2 hours to charge 0-100. Recently the USB cable became unreliable and in order to charge it had to be at a certain angle and kept disconnecting while charging, not to mention taking about a hour longer to charge. I tried using the Aukey charger with the supplied cable it charged approximately from 5-60% in a hour. I was expecting somewhere around a charging time of 30 mins for a 60% increase. For a full charge it took around 1 hour and 30 mins. Does anyone know why quick charge feature isn't working and what I can do to try resolve this?
