Anonymous, 19 May 2020Where is the public statement? Any real proof?
Some Anandtech biased reporters Twitter claims... moreOk. Oppo uses more advanced, faster tech, bigger battery which doesn't overheat, or degrade as quickly so it lasts longer, Happy?
I will still buy the Sony over the oppo and I still believe Sony to be the superior phone and I also believe that the Sony will last 5 years if I need it to. I I also believe that the majority of the people on this forum think the same.
What shall we talk about next? Tell me what else is Sony overcharging and overhyping for that oppo does much better? Please feel free

Some Anandtech biased reporters Twitter claims... moreThat Twitter nerd is the one who does real world Tests. Do you belive a chinese Company lab Tests over real life Tests?? You ask for Proofs but you don't believe those Proofs. Good luck with your Obsession man.
No matter who says what, Li batteries will degrade over time with increased stress and temperatures. 65W will Always excerts more pressure compared to typical 10W or 20W. As I said Nokia,Sony, Apple are not stupid man. Wake up. People who buy These cheap mobiles Change their mobiles in 2 years. It is not biased. Reason why it makes sense to use this Ultra fast charging in These is fine but on a flagship mobiles I think, longevity is important over buy and Change.

Some Anandtech biased reporters Twitter claims?
You rely on twitterati for your info? Lol.
I rely on real world results and testing where Qualcomm quick charge being inferior lowers charging rate otherwise those Ancient charging tech phones might explode or Atleast degrade batteries. VOOC doesn't need to lower charging speeds since the technology keeps temperature in check even if you charge and use the phone at same time.
Again these tests have already been done in the Android authority link I mentioned earlier.
Real world lab test data or some twitter nerd?

Nick.B, 19 May 2020true! news is from last days. trump is so angry :( I starting to hate US just because of himI dont stay on US side but chinese try to tell people that they produce hi-end electronics but thats made on US, Europe and Japan machines and patents. They make good devices but too much copy.
Another wrong side is that chinese delay information about virus.

Iwamoto, 18 May 2020errr...it has stereo speakers and it's 4K, did you even check the specs? ;-)qHD screen is what P40Pro DOES NOT have
1200 x 2640 pixel
mate20pro 1440 x 3120 pixels
p40pro has MONO speaker. ;)))
Sorry fan boy
We have 3 huaweis but this does not make me BLIND for the reality.
mate40pro will fix all that I have big hopes

And if they admit to 70 it is probably more. Or do you think that admitting that their product will not last as long as the competition is part of their marketing strategy?

The link you gave is not for smartphones, and is thereby not applicable as it is for completely different functioning devices, different discharge rates, different surface area, heat dissipation, etc.
Unless you have scientific studies done on fast charging in last 2-3 years on all smartphone brands, don't bother wasting your time.
I am pretty sure, you still haven't fully read about VOOC, have you?
Nor did you pay attention to the thorough testing of different fast charging tech pitted against each other. Those are the true real world results. Rest is therotical garbage.

No body cares about what you think. Ultra Fast (40W+) charging even with bigger batteries is garbage compared to fast charging (15/18W) on a less battery capacity after some time.
Company who made 65W and 50W themselves confirmed it, it's all crock of bs marketing race seeking to have the bigger numbers. You're just one of those fallen pool. Apple/Sony who spend billions in R&D compared to chinese companies are not stupid to still use 18W if Ultra fast charging is available with no losses.

Its still a fact that fast charging is bad, so, unless necessary, don't fast charge.

VOOC wasn't even around then.
Qualcomm quick charge 2.0 wasn't around.
It doesn't take into account several factors.
As I said keep using ancient fast charging data and graphs without incorporating new factors and tech.
It's like comparing efficiency numbers of automobiles 10 years back to current ones not taking into consideration newer tech inside newer cars that improves fuel efficiency.
Unless you have scientific studies done on fast charging in last 2-3 years on all brands, don't bother wasting your time digging up articles from 10-15 years back.

Telephone, 19 May 2020Because you like android authority, I made sure to get you an article from them.
https://www.... moreI don't follow particular tech sites like Anandtech or Android authority or others.
Android authority was the only one to break down different fast charging tech available on market and compared them in detail with thorough tests.
I don't engage in blind brand boyism either.
I am pretty sure, you think I own Chinese phone.
In reality, I don't but I appreciate innovations and superior tech products irrespective of the fact which country they originate from.
BTW, graphene batteries still have a long way to go.
I'd say 10 years.

It turns out to be the same, but with slightly higher efficiency.
4000mah / 2 = 2000mah
30 / 3.7 = 8.10... 8.10 / 2 = 4.05 It is still 4C charging rate per battery cell.
That is still 4 times the recommended 1C charging rate.
Also degradation happens from stress. So not only heat can accelerate degradation.

NOTE: temperature of the battery is kept at room temperature (23C). Yet there is significant degradation because of fast charging.

These are tests run by actual engineers, not some article from the internet.

The phone only increased in Temps by 3-4 deg Celsius while Qualcomm quick charge was getting hot by 20 deg C.
How the heck do you expect degradation when heat is kept in check?
I'll rather believe in depth scientific studies rather than some twitter posts without proof.
You just another hater!
Few years into the future, you'll accept the same fast charging tech after Sony adopts and rebrand it.

Besides, you don't even know that the 65W on Oppo isn't one cell, it's two different cells getting charged at 30 plus Watts each.
This is what happens when therotical junkies like you fail to take into account real world factors.
VOOC is the best right now as explained through thorough testing by Android Authority.

https://www.androidauthority.com/fast-charging-stan... moreOther things to note about OPPO
Oppo claims Ace2 can handle 65W charging on the 4000mah battery (4Ah)
65W is hard to understand so lets change that into C rating.
65W / 3.7V = 17.56756...A 17.56 / 4 = 4.39.. That is 4C charging rate!
40W / 3.7V = 10.81...A 10.81 / 4 = 2.7 About 2.5C rate! (I'm underestimating so its easier to understand)
Here is a chart showing the negative effects of higher C charging. (temperature is a constant) https://i.imgur.com/8vGDFOA.png
It is a fact that charging over 1C accelerates degradation.
By the way, 1C for a 4000mah battery is 4 * 3.7 = 14.8 15W charging is 1C.

OPPO doesn't care about battery longevity. So how is VOOC better if it sacrifices long term performace?
Plus, ultra-fast charging has been around before smartphones ever existed.
I have a 50W Li-po charger. It takes 10min to charge from 0 - 80%

I have seen the degradation. It happens. That's why I will do anything to prevent it.
