  • Flash Charging Technical Paper

    Our use of smartphones and other connected devices is constantly increasing. The number of smartphone users worldwide has reached nearly 4 billion—around half the global population at the start of 2021.

    As smartphone functions improve, they consume more electricity. This increased power demand comes from higher display resolutions, advanced processors, camera systems and more. But as users expect more from their devices, these raised expectations include better battery life—and higher battery capacities mean longer charging times. Fast charging technology was developed against this backdrop of slow smartphone recharge times.

    Fast charging technology can improve charging efficiency, reducing the time to charge devices. Several fast charging solutions have already appeared, mainly falling into two categories: high-voltage, low-current and low-voltage, high current.

    OPPO first offered a low voltage, fast charge solution in 2014, releasing the independently developed VOOC 22.5W (5V/4.5A) flash charger. This device delivered higher charging power, charging devices four times faster than normal charging technology, and 50% faster than other fast charging technologies. In 2018, OPPO made further improvements to VOOC flash charging technology, releasing SuperVOOC.

    This year, OPPO is bringing VOOC Flash Charge innovations to a wider field of applications and user devices. Fast charging technology is expected to broaden out from phones to other hardware.
