Vivo would be testing a new technology for fast charging smartphones, capable of delivering a power of 44 watts, the information is not official, but also comes with a logo that would show the name of this technology: FlashCharge.
Last January 24 was filed at the IPO (Intellectual Property Office) a patent related to the FlashCharge. The fast charging technology should debut on board the next Vivo smartphones, and recently @Sudhanshu also said that vivo is testing a 44W fast charging technology, named FlashCharge.
Vivo Flashcharge should therefore offer charging performance similar to those achieved by Huawei and OPPO, allowing you to achieve a full charge in a very short time and away from the ghost of remaining without energy on your smartphone.
