ngress in Barcelona today, China-based Oppo Electronics took the wraps off a new technology it said can fully charge a smartphone battery in just 15 minutes. Now in the “final stages of reliability testing,” the Super VOOC Flash Charge will be available commercially in the near future, Oppo said.
Since VOOC’s introduction, fast charging technology has rocketed in popularity. Qualcomm and MTK followed OPPO with their own fast-charging technologies: Quick Charge and Pump Express, respectively. These technologies have extended the reach of fast-charging technology, but their underlying principles are actually quite different from VOOC’s. They both apply high-voltage fast-charging, whereas VOOC Flash Charge relies on a low-voltage solution.
Super VOOC Flash Charge can give a full charge in just fifteen minutes.
Secondly, a VOOC-enabled phone maintains a lower temperature during charging than phones using high-voltage charging systems.High-voltage systems rely on a voltage converter to decrease voltage before power is supplied to the battery. This process, however, is relatively inefficient, and it gives off lost energy in the form of heat, which is the enemy of electronic devices. VOOC Flash Charge however, offers an alternative. By keeping voltage at 5 volts, VOOC eliminates the need for a converter, effectively cutting out the middle man, and making for a more efficient and much lower temperature charging process.
Finally, VOOC’s low-voltage charging system is perfect for using your phone while you charge. For instance, you can Flash Charge your smartphone while making phone calls, watching HD videos, or playing games. However, if you try to use your smartphone while using another fast-charging technology, the charger will revert to a standard charging speed, due to the temperature spikes caused by quick charging and screen brightening simultaneously.
