Smartphones that charge slowly suck. And in a world where battery capacities are getting larger by the month, long charge times could become a legitimate gripe. But Qualcomm has apparently been on the case for quite a while now, quietly implementing a technology it calls Quick Charge 1.0 into some of its Snapdragon chipsets.
Quick Charge is actually a physical circuit built into the chipset that interfaces with the USB connector, so this isn't some kind of firmware voodoo. Qualcomm acquired the tech when it bought Summit Microelectronics last June.
Qualcomm claims QuickCharge allows you to charge your smartphone up to 40% faster than one without Quick Charge.
