Vivo has also been working on a futuristic concept phone that has no bezels, and no notch for a selfie camera.
It's unclear when we'll see Vivo's fast-charging solution in a commercially available product — but be warned: fast charging is believed to expedite the deterioration of your phone's battery.
The long-term effects of fast-charging are still unclear, but some studies say that fast-charging your batteries make them die a lot faster.
Our recommendation: As cool as fast-charging is, you should only use it when you need it. Otherwise, using traditional "slow" chargers at night or during the day to top off your device will help it last a lot longer.
