Exactly how quickly do you need your smartphone to charge? Oppo is setting new records for smartphone charging speeds, both for commercial smartphones and in a lab setting.
The headline-grabber today is the company's unbelievably fast 240 W "SUPERVOOC" charging prototype, which can power a 4500 mAh smartphone battery to 100 percent in nine minutes and hit 50 percent in just 3.5 minutes. That's 1 percent about every four or five seconds of charging time. The prototype Oppo brought to Mobile World Congress has a battery percentage readout that goes to two decimal places, so you can watch those numbers really fly upward.
240 W is just for a prototype phone, though, and there's no telling what these kinds of charging speeds would do to your battery after a few charging cycles. For a speed that Oppo is ready to commercialize while still balancing battery longevity, it's also announcing a 150 W charging scheme that will make it into phones this year, including a phone from Oppo's BBK sibling company, OnePlus. (The OnePlus 10 Pro, which launched earlier this year in China, is up to 80 W.)
Oppo's "150W SUPERVOOC flash charge technology" is "capable of charging a 4500mAh battery from 1% to 50% in 5 minutes and all the way to 100% in 15 minutes," the company writes. Oppo is fudging the numbers a bit by starting from 1 percent, but those figures are still blazing fast.
The company says it can do this without destroying your battery thanks to the "Battery Health Engine (BHE)." Oppo says it has built a "customized battery management chip" for monitoring heat and other health factors, along with a new battery formula. Oppo says, "Battery Health Engine is able to keep a battery at 80% of its original capacity after as many as 1,600 charge cycles, effectively doubling the lifespan of batteries under current industrial standards (keep a battery at 80% of its original capacity after as many as 800 charge cycles)." You would need to charge your phone every day for four years to reach 1,600 cycles.
As we've said in just about every OnePlus review, these quick-charging schemes are the best features to come to smartphones lately. When you can plug in a phone for a few minutes to get a ton of charge, it changes user behavior and makes overnight charging a thing of the past. Oppo, OnePlus, and Xiaomi have been doing this for about four years now, and all Google and Samsung have done in response is to start fudging their charger wattages to make them seem faster than they really are. The rest of the industry needs to catch up, but Oppo also notes it has already been granted over 1,300 patents for its charging technologies.
