Qualcomm's New 'Quick Charge 5' Will Charge Android Smartphones to 50% in Five Minutes

I know some companies already admit that it’s terrible. https://androidcommunity.com/oppo-admits-fast-charging-degrades-battery-life-considerably-20200511/
QC5 is supposed to be 70% more efficient by using split batteries with parallel charging that will heat the battery even less than QC4.... So no, it won't kill battery lifespan, on the contrary.... It will only work with upcoming devices, not older ones. Also, you are not obliged to use it, you can always use slow charging (as for instance I do at night...)
"In addition to offering much faster charging, Quick Charge 5 is up to 70 percent more efficient and up to 10 degrees Celsius cooler compared to Quick Charge 4 and 4+. Qualcomm says there are 12 separate voltage, current, and temperature protections included."
I'm pretty suspicious of Qualcomm's claims. Almost never is faster charging cooler. Not unless the chips are GaN based and they are talking about the charging equipment being lower temp - I find it very hard to believe the battery can charge a lot faster and be considerably cooler, that's not how the physics works - I have an MSc in this sort of stuff.
I've yet to see faster charging not resulting in lower battery longevity - in everything from Tesla's and Porsche's to smartphones.

If it does what they claim, it absolutely is innovation.
Lots of people here commenting on something they know ***** about.
Yours stands out, hats off.
Yup. P=IE and P=I^2R unless they have fairy dust in there somewhere.

Apple, please no. Unless Samsung is the first to market with solid state batteries (which would be huge) I don’t want this.
World’s Fastest Commercial Charging Solution: Qualcomm Quick Charge 5 announcement | Qualcomm
Please join Josh Warner, Direct of Product Management for Quick Charge for the exciting announcement of Qualcomm Quick Charge 5. Josh will walk through how Qualcomm created the world’s fastest commercial charging solution.
Video explaining the new system!
When Qualcomm released Quick Charge 3.0 they claimed "Quick Charge 3.0 is up to 4–6 °C cooler, 16% faster and 38% more efficient than Quick Charge 2.0". It was still hot AF.
When Qualcomm released Quick Charge 4.0 they claimed "Quick Charge 4 with Dual Charge++ is up to 5 °C cooler, 20% faster and 30% more efficient than Quick Charge 3.0 with Dual Charge+". It was still hot AF.
Forgive me for not buying the marketing for Quick Charge 5.0.

I think it's hypocritically hysterical that there's loads of mockery citing exploding android phones that skip right past this part of the article.
Also skipping that this standard has already existed and is not responsible for exploding phones...
And if we *really* want to poke fun: keep in mind that it was apple recently who "tried" to develop this little known thing called AirPower, repeatedly failed, and then scrapped it after it already went public that it was an upcoming product.
Meanwhile, Apple was the company that for many, many years kept delivering 5w power chargers, only *very recently* started including stronger chargers in the higher tier models, only to be rumored to be axing that entirely.
Despite this, one can go on Amazon and purchase mutli-port PD chargers with USB-C and USB-A ports for charging multiple devices quickly, and inexpensively, while being well built. The new one is they're all developing reliable 100W PD chargers that are significantly cheaper than Apple's bricks.
tl;dr y'all are laughing in the wrong direction.
That's pretty funny
Qualcomm could only be partially to blame though. They may have a specification that does produce the results they profess but the recommended implementation may not be followed by Android phone manufacturers for a myriad of product reasons. This is where Qualcomm could be at fault: don't over market a technology that no one is going to implement to meet its full potential.
Bye-bye battery longevity. I am sure Qualcomm is trading battery longevity for significantly quicker charging. I don't think that if you consistently use this quick charge (like every day for 2 years) that it will have the same battery life as an iPhone that uses Apple's Quick Charge adapter or even a third party quick charger that charges at 7W max.
If Apple announced this, people would be praising and drooling.
Certainly a 100W charger won't be a standard offering out of the box. That means those who want or need fast charging can consciously decide to make the longevity trade-off. Having the option when you need it is awesome, even if 95% of the time you are charging at, say, 10W.
Comment referred to OP where it’s claimed “waiting to see innovation from Apple”(sic) where innovation seems to be a personal moving definition.
I read that as saying the charger is cooler, not the battery. The charger doesn’t know the battery temperature.
This might be ok in an emergency, generally, faster charging cuts battery life.
I’m glad Apple is using industry standard USB-C + PD, not proprietary Qualcomm crap.
Same. This will be THE reason why I update my iPhone next. I just updated my Anker external batteries to this. USB C all the way now.
