Oppo says that's about how much time it'll take to charge a dead 2,500mAh battery to 100 percent, and that the technology will work over traditional micro-USB and USB Type-C cables. That's even faster than what we've seen out of Qualcomm's most recent Quick Charge 3.0 demos — the fast-charging technology baked into chipsets like the Snapdragon 820 can get a smartphone from bone-dry to 80 percent in around 35 minutes. Of course, it's sort of no surprise that Oppo can squeeze better performance out of their system — it's more or less proprietary Oppo, so the company has full control over the battery, silicon and software involved. That's the sort of end-to-end control that helped Huawei figure out how to supercharge smartphones, too.

In some cases, you'll be able to get a full charge in less than 15 minutes. An Oppo hype man plugged a metal-encased reference device into a charger and continued his spiel in Mandarin. Less than ten minutes later — after he discussed an algorithm that varies current to maximize charging efficiency while keeping temperatures low — the phone was back up to 100 percent. Our natural skeptics can't help suspect this was just a staged demo for the show, so here's hoping we soon get to test a SuperVOOC phone for ourselves.
