I've had a new Galaxy S3 handset a few days and just received a desktop cradle/dock for charging during the day. The USB cable is plugged into a mains powered USB hub, but the phone itself doesn't seem to be charging; It's gone from 33% to 34% in the past 5 hours.
The phone is connected to the mobile network, with WiFi and Bluetooth enabled. Even though, I'd have thought a powered USB hub would provide enough juice to power the phone and charge it? I've been searching the net and found a few cases where the phone hasn't been charging via USB, so wondered if it was a common issue?
