HyperCharge, the company also claimed, could deliver a 50 per cent charge in three minutes. To preserve battery health, charging speeds typically decelerate as a device reaches full capacity.

The company claimed the fast-charging tech would allow a 120W charger to fully recharge a 4,000 mAh battery in 15 minutes.
Xiaomi has not confirmed whether HyperCharge will eventually make its way into a production device.

The technology was demoed on a modified version of the [10]Xiaomi Mi 11 Pro handset , which typically comes with 67W wired and wireless charging, and 10W reverse charging.
The company's fastest charging on a production device can be found on the [11]Mi 10 Ultra , which supports 120W wired charging.
Vendors swimming in the choppy waters of the Android space often struggle to differentiate their devices from those made by their competitors.
[12]
Phones are, effectively, bundles of components made by a handful of downstream vendors. It doesn't matter whether you buy a Xiaomi or a Realme, what you're getting is a chipset from Qualcomm, a camera module from Sony or Samsung, RAM from SK Hynix, and so on.
There are very few avenues of differentiation available to manufacturers. Software is one. Charging is another. Over the past few years, we've seen a lot of competition in this space, with Xiaomi, [13]OPPO and OnePlus trying to best each other.
In the case of OPPO, it's also started licensing its own VOOC fast "flash" charging IP to other tech companies, most notably Anker, which has said it will use the tech [14]across its line-up .
[15]
Nonetheless, there are some major problems with fast charging. It has a tendency to increase the wear and tear on the battery, shortening longevity.
It's for that reason why some vendors – including Apple – opt for slower charging speeds when the device is plugged in at night. Others, such as [16]ASUS , also offer the option to manually reduce charging speed. ®

Re: Stupid lab tricks
If you're going to pick holes in things because you're so clever, at least have the courtesy to explain to us mere mortals what "1C" actually means, given there's no mention of such a unit anywhere in the article??
Re: Stupid lab tricks
Using a little Google Foo I discovered that it is the rate to charge a battery of 1Ah (1000mAh).
Which means a 4Ah battery would literally be 4 hours to charge.
Note: the little I read on it mentioned that 1Ah should be able to discharge at 1A for 1h.
Re: Stupid lab tricks
Thinking my above sounded a little weird I investigated some more.
C=Capacity[Ah]/1[ℎ] (See IEC_61434)
Re: Stupid lab tricks
er... so "C" is another way of saying Ampere? [1] !C is charging at 1 amp?
Thank goodness, that old "amps" unit was way gnarly and old-fashioned.

[1] No, surely I must be wrong. I must've misunderstood. Surely...?
Is this really useful for anyone?
What's the actual use case here? I can see it for EVs, but not really for phones.
If I'm going out for the day, then I'll stick the phone on charge in advance of leaving the house. If I have to leave first thing, I'll stick it on overnight, and it can trickle top up while I sleep.
I don't really see a use case, at least not for myself, where 200W charging would be useful!
Even if I get an unexpected call to head off somewhere at short notice, my now rather ancient OnePlus 3 can stick a decent amount of charge (about 30-40%) in the phone in the 10-15 min it would likely take me to grab a shower and throw some clothes on, and that's assuming I'm on foot. If I'm in the car, I can charge it there.
This just seems to be a case of bigger number = better marketing, i.e. I can pee higher than you!
Anyone out there who'd find it actually useful? The charging, not the pee ;-)

Re: Is this really useful for anyone?
Numbers sell phones
Numbers users understand: Camera megapixies, big = good, Charging time, small = good.
Other numbers are for the sort of nerds who agonize about specs and then buy Google/Apple
Re: Is this really useful for anyone?
Yep. Solution looking for a problem.
I can remember my first analogue mobile, nearly 30 years ago. 8hr battery life (so long as you didn't use it much) and 8 hrs to recharge. 10 minute charging would have been great.
But now? My Android Honor thingy can run for a couple of days on a full charge (depending on usage) and fully recharges from 20% in under an hour. I charge it at night.
And it doesn't need a separate charger - just a standard USB-C plug.
Stupid lab tricks
This is great, but when you charge a Li-ion battery at faster than 1C, it roasts that puppy, and battery life goes straight into the trash.
> To preserve battery health, charging speeds typically decelerate as a device reaches full capacity
Not true. Charging speeds typically decelerate because the Battery Management System stops charging cells with higher voltages to let lower charged cells catch up and level out mismatches.
To preserve battery health, you simply don't charge faster than 1C, especially when the battery is hot.
