BARCELONA, Spain — Imagine charging your phone in 15 minutes or less. At Mobile World Congress 2016, Oppo said it can do it. When I went to their booth to see it for myself, that’s pretty much exactly what happened.
To make the demo, Oppo modified one of its Find 7 smartphones to have a 2,500-mAh battery and installed a bit of tech wizardry that it calls Super VOOC Flash charging (Voltage Open Loop Multi-Step Constant-Current Charging). The acronym doesn't quite work, but I digress.
The reps drained the battery till it was almost dead (8 percent), then turned on the power, and sat back while electricity floods into the phone’s battery like the tsunami from Armageddon. According to Oppo, to accurately time the charging, you can't start the test at absolute zero charge.
Oppo’s Super VOOC pushed 2,285 mAh of electricity into the phone is in just under 11 minutes and 30 seconds. But really, the charging is faster than that, because Super VOOC slows down quite a bit when it hits about 85 percent of the battery’s capacity, so as to prevent any damage to the device. And because Oppo is using low voltages for Super VOOC, it says there won't be any negative impact on the life of the battery.
Oppo says that Super VOOC probably won't make it onto its next phone, but the tech will definitely make an appearance sometime in 2017, with an outside chance of showing up in late 2016 if everything goes perfect.
At rates like this, Super VOOC is even faster than the Quick Charge 3.0 tech that’s been featured on a number of Qualcomm’s Snapdragon-equipped phones such as the LG G5 and HTC One A9. In fact, Super VOOC may even finally silence those who constantly berate phone makers for not making devices with removable batteries, although I wouldn’t count on it.
