Hello again.
I spoke with the UK E-Store and Support the other day.
I'm deliberating on whether to send my replacement UCH12W charger back for a refund. They've given me that option; or have another replacement (!)
I notice they were selling it online with 30% off the past week for 'Black Friday Week' (as they call it here).The thought did cross my mind to send my replacemnt back for a refund and buy a new one at the discounted price. But why bother in the circumstances?! And in any case, it's back to it's original price again now.
Sony support have suggested I do a software repair of my XZ using the Xperia Companion app to resolve my issue.
They also confirmed that the phone should support Quick Charge 3.0 and that it didn't matter whether I had adaptive charging on or not. It wouldn't make a difference. They also said it wouldn't say "rapid charging" or "charging rapidly" on my XZ with the quick charger, just 'charging;' unlike it does when charging my Quick Charge 2.0 devices.
It's quite a big step for me to do a software repair on my phone because of it resetting so many things I use and rely on regularly so I'm not rushing into it.
Incidentally I thought I'd mention that the cables that come with the UCH12W are thicker and more robust to handle Quick Charge 3.0 than say the one that came with the phone or the previous Quick Charge 2.0 UCH10 charger. It shows you the details on the labels on the cables if you're interested.
Wishing everyone the best of luck to get this issue resolved properly.
