Proven Shmoov'n,..they HAVE proved they can charge a phone in 9 mins! I also agree that APPLE is so slow in adopting ANY new or updated technologies. With the amount they bank, it should NOT take years to develop and test anything!

The retractable lens concept may be a different subject…😏
Meanwhile Apple with iPhone's 500 charge cycle. Tim Ca$h: - I'm going to pretend not to see that. 😏
Seriously, my 12 Pro in it's first year had the worst battery life with the capacity degrading rapidly in the first 6-8 months to 87%, it was after one of the updates did it stop and now at 85% am I getting some fair daily usage without needing charge in between.
It doesn’t matter what Apple has in the bank, if a supplier can’t physically make over 100 million in less than a year, it’s not going into an iPhone.
It would be nice if we knew what kind of battery really is in use. Li-ion batteries have some limits. It is well known that small li-ion cells wear faster at high currents than big sized ones (like in EV's). In 10 years development of li-ion hasn't really made really significant improvements. Yes, they've become more safe and there's a bit more capacity per volume, but that's basically it. The lithium material still wears down, even when sitting on the shelf. The industry still is searching for better material combinations.
But it could also be simpler. What if this Oppo phone just uses less power and has a smaller battery too? Then it will have shorter charge time (at regular currents) and still have about the same talk-time. Sounds stupid, but this has been done before.
A while ago I bought a couple of rechargeable D-size batteries off the internet that had the same kind of marketing: extreme fast charging and lightweight. While I only bought them for the physical size, soon the marketing scam became clear to me. The battery shells were actually 50% hollow!!! VARTA used a smaller NiMH core inside, comparable to a AA-size battery. So indeed they were lighter and charged faster (at standard currents), but had way less capacity. So basically a more expensive AA-battery with an D-size adapter around it.
My 13 mini does a hell of a lot faster than 50% in a half hour.
Oppo has announced a record-breaking fast charging technology that is around twelve times faster than the iPhone 13 lineup.
On the first day of 2022's Mobile World Congress (MWC) yesterday, Oppo showcased a range of technologies, including its latest Find X5 series of smartphones, the MariSilicon X custom image processor, a retractable camera system, the Air Glass extended reality monocle, and more. Among the announcements and spotlights, Oppo announced two new fast charging technologies.
The first, which Oppo calls "150W SUPERVOOC flash charge," features charge pumps and can charge a device with a 4,500 mAh battery to 50 percent in five minutes and deliver a full charge in just 15 minutes. 150W SUPERVOOC includes Oppo's Battery Health Engine, which recently debuted in the Find X5 lineup, to keep the battery at 80 percent of its original capacity after as many as 1,600 charge cycles – double the industry standard of just 800 cycles. Oppo will introduce 150W SUPERVOOC on selected OnePlus devices in the second quarter of 2022.
The company also revealed "240W SUPERVOOC flash charge" technology, which can charge a 4,500mAh battery to 100 percent in just nine minutes. 240W SUPERVOOC is the fastest-ever charging technology of its kind, surpassing Realme's 150W charging.
Oppo says that the 240W SUPERVOOC charging system contains five safety protection measures, including a custom-designed control chip that monitors voltage, current, and temperature, and conforms to standards for heat dissipation despite the very high power output. Oppo did not say when the first devices with 240W SUPERVOOC will be released.
Apple's iPhone 13 mini and iPhone 13 support wired 20W fast charging, while the iPhone 13 Pro is able to support up to 23W and the iPhone 13 Pro Max is able to support up to 27W. The iPhone 13 models do not sustain peak power for their entire charging cycle due to thermal considerations.
With a 20W power adapter and a Lightning to USB-C cable, users can charge an iPhone 13 from zero to 50 percent in half an hour, and fully charge in about two hours, which is significantly slower than either of Oppo's new charging technologies. Last week, Oppo announced plans to directly compete with Apple on a global scale with a wave of premium devices, starting with the Find X5 models.

I did the math, and, assuming USB-C charges at 5V, that gives this a current of 48 amps! The limit on North American circuits are 15 to 20 amps. My brief research suggests that USB-C still operates at 5V normally, but that the 20W Apple USB-C charger operates at 15V in fast mode, giving a current of 1.33 W. In order to give a current that won’t cause an overcurrent on most home circuits, this charger would have to be operating at somewhere between 15V and 20V minimum. Can USB-C even handle these currents?
For what it’s worth, it’s most likely charging at direct AC voltage (110V in North America), giving it a current somewhere between 1-2 amps. But this isn’t some USB power brick, this is going to be the size of a desktop CPU’s power supply, at least if it’s operating at 120V AC and outputting 120V DC.
The more I think about this, the more I question it and the more it makes my head hurt.

A big honking huge charger, for one. 120V DC output power supplies are about the size of a small PC tower! It’s either that or currents that are about as high as a space heater at full blast (imagine tripping the circuit breaker because you wanted to watch TV and charge your phone at the same time)!
I was looking at the iPhone and the port as a reason not to update to FC.
certainly impressive. iPhone certainly would be welcomed with faster charge time for sure.
Todays USB-C PD specification: 100W maximum, 5A at 20V max. With this specification a 240W delivery would only be possible using 3 USB-C PD ports. Oppo probably has extended the specification to something like 6A at 40V. This is proprietary of course and only very few devices and cables will support that. Do I smell burning cables? ??
Looking at other chargers, there are many sold on the market that claim to support 100W, but in practice very few of them can deliver 100W on one port. And only if the cable / device connected is compatible.
The extreme fast charging probably works fine, but it still takes time to see for how long this continues to work reliable and cost efficient. I wouldn't use it if the battery needs replacement every other month or so.
But why wouldn’t you charge your phone overnight? What’s the downside?
I already don’t think about battery % because my iPhone 12 Pro always lasts the entire day, as has every iPhone I’ve ever owned.
The only time I have to expend any concern over my battery - when I’m hiking/camping over night - this technology doesn’t even solve for!
It is a mind set change.
Charge as needed instead of scheduled charging.
They both have their benefits and detractions.
It’s something you will get after using it that way. +1 to the mind set change.
