If CPU support Qualcom Quick Charge 3.0 , does the phone also has it?

[Altin Guberi]

Alright the example is with Snapdragon 435. Redmi 4x has such CPU but the company says it support Fast charge 2.0.

So I want to know can I use a quick 3.0 charger?

If the answer is yes,

In order to enable Quick charge 3.0 is there required additional hardware support except CPU or just software update?

Thank you.
