At Mobile World Congress in Barcelona this week, Chinese phone company Oppo has shown how far it’s come in battery technology. The company demonstrated a prototype smartphone with a 2,500mAh battery that could charge in just 15 minutes.
Fifteen minutes is exceedingly fast by anyone’s standard. The device equipped with Oppo’s new SuperVOOC system was shown to charge from 5 percent to 58 percent in five minutes, which means you could get around ten hours of talk time even if you could only charge your battery when leaving home in the morning.
Oppo says the new “SuperVOOC” tech uses a low voltage pulse charging method to charge devices safely without raising their temperature too much. Custom hardware (an upgraded battery and military-grade components in the charger and phone connector) also help achieve the lighting-fast times.
The firm said that SuperVOOC maintains the low temperatures when using the phone while charging, yet still manages to top it up efficiently.
It’s an exciting new method of charging, as batteries don’t appear to be improving fast enough to provide an extended life and the small sizes necessary for mobile devices.
Oppoo says that SuperVOOC is superior to other quick-charging systems offered by companies such as Qualcomm and MediaTek, because it operates at a lower voltage and minimises the risk of overheating.
No new models have yet been announced with the tech, but Luma Lu, Oppo’s technology planning director, says he’s confident the firm will ship devices with SuperVOOC later this year.
