Chinese smartphone maker Oppo did hint at having some major innovations in store for MWC, and the surprises it unveiled are downright impressive. First off, the company showed off its new Super VOOC quick-charging technology. With it, Oppo claims it's able to charge an empty 2,500mAh battery to 100% in just 15 minutes over MicroUSB and USB Type-C cables. That's pretty crazy, considering high-profile competing solutions such as Qualcomm's QuickCharge 3.0 — present in its latest chipsets, such as the Snapdragon 820 — take up to 35 minutes to fill up a battery to 80 percent.
Moreover, Super VOOC's low-voltage charging allows for fast-charging your smartphone while using it. Other fast charging technologies revert to a standard charging speed while the handset is in use, due to temperature spikes caused by the simultaneous quick charging and screen brightening.
Oppo's Super VOOC tech is proprietary and unless they license it to other manufacturers, it will be a mainstay of its own smartphones. The company can pull off its fast charging magic off thanks to an all-new low-voltage pulse-charge system, in combination with a customized battery. The system uses a new algorithm to dynamically regulate the current, ensuring the fastest charging time possible while maintaining current within the battery's safe range. To complete its solution, Oppo redesigned the Super VOOC Flash Charge adapter, cable, and connector with military-grade materials to make them reliable and rugged.
Besides Super VOOC, OPPO showcased a proprietary image stabilization technology called SmartSenor. This is supposed to be a first in world pixel-level OIS (Optical Image Stabilisation) solution. SmartSensor employs a sensor-based 3-axis stabiliser, while most (though not all) lens and motor-based solutions are 2-axis and usually implemented in flagship smartphones only. Oppo's tech takes just 15 milliseconds to achieve "comprehensive" image stabilisation for blur-free shots and shake-less video. According to their expertise, traditional lens-based stabilizers take at least 50 milliseconds to react to camera movements, which means Oppo's solution is about three times faster. It's also touted as more practical and being able to compensate for a greater range of motion.
Moreover, SmartSensor is said to greatly reduce power consumption, which helps avoid lens heating. Traditional lens-based image stabilization modules use an electrically powered voice coil motor, which consumes over 500mW of power with each photo, and quickly heats up when taking photos for extended periods of time, which impacts lens performance and lowers image quality. SmartSensor uses a voltage-driven sensor, which reduces electricity consumption to as low as 10 milliwatts.
OPPO did not reveal which smartphones will carry its latest technologies, but they could become staple features of its upcoming, and long in the making Find 9 flagship smartphone. The company is taking its technological research seriously, coming up with ways to make our smartphones even more awesome than they are now.
