as the title says,
How long does it take to fully charge your Z1 from 0%?

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?

From 5% left charge to full. Three hours

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).

what you said does really make sense because quick charge 1.0 promise ~40% faster charge which I reported in my first post (+1 for that). Now is there any way to check whether the Z1 support quick charge 2.0? I know the chip S800 does, but what about the battery software or other internals (I am not really expert in this area). if it does then when new adapters are released with output more than 1500mA we will get faster charge time. I have my nexus 7 charger which says 2000mA, would this make difference and would it hurt the Z1 battery if I used it?

One last thing, if the output is 3000mA does that mean half the charging time? or there are other things to take into account?

All Snapdragon 800 chips have the QC2.0 circuit so we're good. Just have to wait for chargers.

I'm not an electrical engineer (studied mechanical) so I can't comment on things like losses within the charging process and all that technical stuff. However you have the concept right and in general that should be true. 3A charging a phone should charge it twice as fast as 1.5A

I've just made one test from 6% to 100% it take more than 2 hours i don't know if it was with qcharge 2 i've used the dk31 with a old AC to usb.
Other charge are made from 30-40% to 100%.

Mine takes an average of 2/3 hours to charge from 5% to 100%, I do however only use 1 Amp charges which are old phone chargers. I think I shall get my Note 2 plug out which is a 2 Amp charger and see how that gets on, I totally forgot I had it and I kinda annoyed me with its hissing noise...Even though I found out later it's normal!

The charge time is a joke compared to iPhone 5. The only thing that annoys me about the phone

The iPhone 5 has a battery half the size of this... I personally take about 2 -3 hours to fully charge the phone using the Sony provided charger!
