Slow charging with better Sony cable (UCB20 vs UCB30)

[Sapphirus]

Hello guys,

I compared these two cables:

UCB30 with charging output upto 15,0 V / 3,0 A

UCB20 with charging output upto 12,0 V / 3,0 A

So I decided to upgrade UCB20 cable which came together with UCH12 charger (with XZ1 phone) and purchased UCB30 which is faster in terms of data transfer and should charge faster as well.

But from 70% of the battery charging with UCB20 phone says 30 minutes to 100% and with UCB30 1h 50m.

What´s the problem here, can anyone explain, please?

Thanks.

T.

I don´t know why the charger switch from normal charging to QC 3.0 when connected via attached UCB20 only..

There are more things I don´t underestand tbh. UCB30 is the USB 3.1 Gen 2 cable capable 10 Gb/s but phone has only USB 3.1 Gen 1 (which I underestand doesn´t matter - it will just work 5 Gb/s).

Is there someone else who can confirm me the same results with UCB30 cable?

When charging a device with UCH12,always use the UCB11 micro USB cable.

but the XZ1 owns a USB-C port.

you can't use the UCB11 cable.

Yes,there are two chargers,UCH12 and UCH12W. First is with UCB11,second with UCB20(type C) cables.

actually there is only one charger : its name is UCH12.

UCH12W is a pack which contains the quick charger UCH12 et two cables UCB11 (micro USB) & UCB20 (USB type C).

I think the 'W' in 'UCH12W' stands for Wire(s).
