My nexus 7 2012 edition is charging 5% for an hour Via USB. It seem to charge fine via its adapter but damn slow via USB. I am using my desktop as the charging station.
USB 2.0 only offers 500 mA @ 5 Volts (2.5 Watts) whereas USB 3.0 offers 900mA (4.5 Watts), which is bad for any device's battery which is designed to charge at higher rated current. Not good for battery life.
