Charging my phone doesn't seem to work properly

[Kryptonian1]

The Xperia XZ Premium comes with a quick charger 3.0 and a typ c usb cable, so all that means that the phone should get charged fast, correct? 

Well, it takes me to charge it from 50% to 100% two hours, which can't be right at all. The charging process gets EXTREMELY slow once it reaches 80%, but that could be just a throttling implemented by Sony, dunno.

Regardless, I have tested the original charger and another one from Amazon; same result. I've charged with the phone being off and on by the way. So, the phone itself has a defect? Battery performance is very good and it doesn't get hot at all, though.

Nice to see a fellow German guy! Anyway, yes, it is indeed a quick charger, for I just called the customer support and they confirmed it. According to that gentleman, it'll take maybe a week or something until that charger starts charging faster; in the beginning, it's all about getting used to and stuff. 

That it gets very slow starting from 80℅ is also normal; that's a precaution thing, so the battery won't get damaged etc. It does charge fast when the battery percentage is very low, yeah.

To the other guy: there is no notification when using a quick charger; it's a Sony thing.

I got a German model too also included a quick charger - interestingly almost every German review I saw so far complained that there was no quick charger.

Items in a box vary per region and even in the same country with different carrier networks.
