mine takes 2.5 - 3 hours, I do think that this is quite a lot although it is faster than my old xperia S which took ~2 hours with almost half the battery size. But I was expecting more improvement from the promised 70% with quick charge 2.0. This is around ~40% improvement, or am I missing something?
I don't think Quick Charge 2.0 adapters are out till early 2014. Even if they are, the one that came with my Z1 doesn't support it. Only Quick Charge 1. You can tell because the output is listed on the adapter (mine is 1500 mA).
Quick Charge 1 works on .7 to 2.5 A. Quick Charge 2 is 4+ A. (Standard USB 2.0 port will provide 500 mA while USB 3.0 will provide 900 mA).
So my 1.5 Amp Z1 charger isn't even at the top end of Quick Charge 1. With that said, I haven't tested a full charge. But if plugged into a USB 2.0 port, it barely charges while phone is on (few percent an hour maybe).
