I'm not sure exactly how they do it, but I'm gonna guess that because the heat stays in the brick, they have parallel engines for the charging with circuitry to keep the great under control

Walter C. Dornez, 09 Sep 2019Then higher amperes is kinda dumb then. Agreed, but I think Oppo is using some unique charging design, thicker cables for lower resistance and probably a battery made up of cells that get charged in parallel. I wish I knew how they actually did it though.

Walter C. Dornez, 08 Sep 2019I see. Don't higher amperes degrade the battery faster though?In isolation Yes! If you only think about it on paper sure BUT!! Vivo deals with the high current issue by making wider cables to compensate
Thinking about the amperes PLUS the hardware of the charger is what will give you the entire picture
And I stress again higher ampere is no issues under this context

AnonD-454049, 06 Sep 2019Vivo's working on 120WYes i know.
But besides of that back in 2014 a 18 years old girl invented technology of super fast charging on youtube there are plenty of videos of charger which can top up your phone in less than 30 seconds or uop to 1 minute.
Just an example: https://www.youtube.com/watch?v=pdEWw1LOO2I

Alright then I guess if we increase voltage it won't have any impact on overall power and heat whatsoever
I will always have much to learn in physics so I'll take your good advice and read a physics book
We can't all be like you who've mastered the subject perhaps you've written a book of your own for me to buy and educate myself

Nor did I agree with you, you said higher voltage means more heat and that's not what I'm saying. It wasn't the order of the formula that was wrong, it's the usage of non-standard symbols. You clearly have no clue what joule heating is. Also, I know what electromotive force is. Again, go and study physics.

You jus basically agreed with me and then tell me to learn physics lol
That's exactly the point it's going to heat the WIRES that's why I mentioned the wider lanes because the cables get thicker
Voltage will direct the heat straight to the battery....
Voltage is the FORCE that pushes the current from point a to b
You isolated the rules of physics and never put in to context the battery Vs the charger

Picture a highway, you can manage traffic by making cars drive faster In a single lane( voltage)
Or you make more lanes (amperes)
Higher voltage means more heat Vs increasing "bandwidth" in the case of amperes less heat
As we know Voltage times ampere equals watts (V x A =W)
That's why even if two phones charges at 30W
(10V x 3A) is arguably worse than (3V x 10A)
