Oppo teases phone with upgraded Super VOOC, 4,000mAh battery for later this year

05 September 2019
There's a good chance that this is the same device Brian Shen teased earlier - the upcoming Reno flagship with a 90Hz screen.

TheWanderer, 09 Sep 2019Agreed, but I think Oppo is using some unique charging design, t... moreYou're right actually. 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

IpsDisplay, 09 Sep 2019In isolation Yes! If you only think about it on paper sure BUT... moreOh yeah, they use dual channel charging. That'll take care of the heat and would be optimized enough to still have fast charging. Still, is it better than the Power Delivery on the Note 10 series?

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




TheWanderer, 09 Sep 2019Yes, through increased heatThen higher amperes is kinda dumb then.

TheWanderer, 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

Walter C. Dornez, 08 Sep 2019I see. Don't higher amperes degrade the battery faster though?Yes, through increased heat

Walter C. Dornez, 08 Sep 2019Probably will happen with graphene batteriesHmm

TheWanderer, 06 Sep 2019Can't wait for the 120W Super FlashChargeProbably will happen with graphene batteries

IpsDisplay, 05 Sep 2019Time for the good old highway example Picture a highway, you ... moreI see. Don't higher amperes degrade the battery faster though?

IpsDisplay, 06 Sep 2019How I described it is exactly the approach that oppo does with t... morelol you're insulting me directly just because you don't know physics. How pitiful.

TheWanderer, 06 Sep 2019I didn't "isolate" anything. Nor did I agree with you, you said ... moreHow I described it is exactly the approach that oppo does with their super vooc

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

IpsDisplay, 06 Sep 2019I was wrong to flip the the formula it is indeed V x I and not I... moreI didn't "isolate" anything. 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.

TheWanderer, 06 Sep 2019Lol learn some physics, high current increases heating in wires ... moreI was wrong to flip the the formula it is indeed V x I and not I X V ( I used ampere to simplify for others)

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


CptPower, 05 Sep 2019Expecting 90 or 100W and they can do that i am sure of it. Vivo's working on 120W

Walter C. Dornez, 05 Sep 2019Maybe, though maybe they're talking about sustained 50 W? In tha... moreCan't wait for the 120W Super FlashCharge

IpsDisplay, 05 Sep 2019Time for the good old highway example Picture a highway, you ... moreLol learn some physics, high current increases heating in wires due to joule heating. And the formula is P= V x I

IpsDisplay, 05 Sep 2019Time for the good old highway example Picture a highway, you ... morethanka

Walter C. Dornez, 05 Sep 2019What's the difference exactly between increasing Voltage and amperes?Time for the good old highway example

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)
