MWC 2016: Smartphone to fully charge in 15 minutes
China’s Oppo claims its new fast-charging technology will boost battery power in 15 minutes
Chinese smartphone manufacturer Oppo revealed at Mobile World Congress it has invented a technology which will charge a smartphone's battery from zero to 100 in just 15 minutes.
Oppo claims its Super Voltage Open Loop Multi-step Constant-Current Charging or Super VOOC Flash Charge technology would charge a 2,500 milliampere-hour (mAh) battery within 15 minutes using a low-voltage pulse-charge system, operating at 5 volts (v). Oppo said this would enable a lower battery temperature and a five minute charge will result in 10 hours of talk time.
In comparison, Qualcomm's Quick Charge technology can charge a smartphone with a 2,750mAh battery from zero to 80% in 35 minutes using up to 12v. However the chargers are only compatible with devices that have Qualcomm Snapdragon processors.
Oppo stated its technology is safer and better for battery longevity as it operated on 5v, and can adjust the current to maintain the fast charge rate without damaging the battery.
The Super VOOC Flash Charge technology is likely to feature on forthcoming smartphones released from Oppo, but will not be compatible with non-Oppo smartphones.
Oppo sold 50m smartphones globally in 2015 and is one of the largest Chinese smartphone manufactures behind Huawei and Xiaomi.
