Oppo and OnePlus Promise 150W Charging
OnePlus will introduce a phone this year using a new technology from Oppo that can entirely charge a 4,500mAh battery in 15 minutes, the companies announced at Mobile World Congress on Monday.
"150-watt SuperVOOC is a technology which will debut on a OnePlus device in the second quarter of this year," OnePlus head of product strategy Chris Shu said in a roundtable discussion.
Oppo's 150-watt SuperVOOC charging outputs 20 volts at 7.5 amps. It works with phones that have two battery cells, splitting the power into two charge pumps that supply 5 volts at 15 amps to each cell.
Oppo promises that the charge adapter will use gallium-nitride technology to be only slightly larger than existing 65-watt adapters, at about 2.3 inches long and 2.2 inches deep.
One of the concerns about super-fast charging tends to be whether it will wear out cells quickly, but Oppo says it has that under control. The company's "battery health engine" will keep a battery at 80% maximum charge level after 1,600 recharge cycles, the company says.
A "battery health algorithm" and "battery healing technology" control the charging current and protect the electrodes against degradation, according to Oppo.
The phone's fast charger will also support USB-C PD and Qualcomm QuickCharge protocols, letting it charge other devices quickly, Shu said.
The BBK companies, which include Iqoo, OnePlus, Oppo, and Vivo, have been on the cutting edge of fast charging for a while. The OnePlus 9 Pro's 65-watt "warp charge" is currently the fastest-charging phone in the US.
So far, the fastest charging I've seen overall is 120 watts on Iqoo's weird, BMW Motorsport-branded Iqoo 9 Pro. It got the phone's battery to 24% in five minutes and to a full charge in 25 minutes.
